Abstract:

Background: Lao PDR still has challenges in preventing and managing health against risk of emerging and re-emerging diseases, particularly HIV/AIDS, tuberculosis and malaria among pregnant women. Community-based intervention for mothers requires more evidences on awareness of such diseases and access to rapid diagnostic tests. The study aims to determine the awareness of pregnant women regarding HIV, TB and Malaria, the access to rapid diagnostic test of such diseases among pregnant women of local community and their factors related. Method: This is a cross sectional study using quantitative approach to explore the awareness of pregnant women on HIV/AIDS/TB and Malaria in Savannakhet province, Lao PDR in three remote districts (Phin, Thapangthong and Atsaphone) of Savannakhet province. The study targeted group was pregnant women at the community level. Sample size for primary data collection of pregnant women was 189. Face-to-face administered questionnaires were applied. Descriptive and inferential statistics were applied to determine the associated factors with awareness of pregnant women on HIV/AIDS/TB and Malaria. This study is under the HEALTH project/ Expertise France. Result: Most of our participants were pregnant at 28 – 42 weeks (50.3%); ranged 4 – 38 weeks. Mean age of pregnant women was 24.3 years old (range: 14 - 48 years old); 15.9% of whom were at age below 19 years. Around 94.2% of respondents works were farming, 54.5% were illiterate, 74.0% were Mon-Kmer ethnic, and 60% had income lower than average. Only 56.6% that have access to ANC, 39.1% started the access to ANC during the first trimester and only 19.6% had visited the ANC for at least four times. Almost pregnant women (and 92.1% and 93.1%) had low to moderate knowledge of HIV and TB respectively, while three-fourth of pregnant women (74.6%) had low to moderate knowledge of malaria. Slightly higher than half of participants (53.4% and 52.9%) had easy access to HIV and TB respectively ; while 72.5% had easy access to malaria. Majority of participants knew where to get tested for malaria (73.5%) and TB (54.5%), but 73.5% did not know where to get tested for HIV. Very few pregnant women (1.6%, 2.1% and 8.5%) experienced having tested for HIV/TB/malaria. respectively. Factors associated with awareness on HIV were occupation as staff, business (OR:5.9; 95% CI:1.2-28.1), upper secondary education (OR: 14.6; 95% CI:3.1-69.2); Mone-Khmer ethnic (OR: 0.4, 95% CI: 0.2-0.8); and attending ANC more than 4 times (OR:4.1, 95%:1.7-9.7). Factors associated with awareness on TB were occupation as staff, business (OR:2.4; 95% CI: 0.7-8.0), upper secondary education (OR: 6.2; 95% CI: 1.9-20.5); Mone-Khmer ethnic (OR: 0.5, 95% CI:0.3-0.9); attending ANC more than 4 times (OR:2.8, 95%:1.2-6.4). Factors associated with awareness on malaria were upper secondary education (OR: 18.1; 95% CI: 2.3-142.9); Mone-Khmer ethnic (OR: 0.2, 95% CI:0.1-0.4); attending ANC more than 4 times (OR:3.6, 95%:1.5-8.8). Conclusion: A very low awareness on HIV, TB and malaria among pregnant women in rural community of Savannakhet triggers the requirement of comprehensive public health intervention on awareness and access to prevention against emerging diseases for all pregnant women. Future intervention should focus on providing more knowledge to pregnant women during ANC and encouraging them to attend ANC more than 4 times.

Abstract:

The objective of this study is to examine the factors influencing consumer purchasing decisions about healthy food. This model consists of two latent variables: Consumer Perception relating to NCDs and Consumer Perceived Product Value. The study was conducted in the northern provinces of Thailand, which are popular with tourists and have received support from the government for health tourism. A survey was used as the data collection method, and the questionnaire was applied to 385 tourists. An accidental sampling method was used to identify the sample. The statistics of frequency, percentage, mean, and structural equation model were used to analyze the data obtained. Additionally, all factors had a significant positive influence on healthy food purchasing decisions (p<0.01) and were predictive of healthy food purchasing decisions at 46.20 (R2=0.462). Also, these findings seem to underline a supposition that consumer perceptions of NCDs and perceived product value are key variables that strengthens the competitive effects of a healthy-friendly business entrepreneur. Moreover, reduce the country's public health costs for treating patients with the disease of NCDs in Thailand.

Abstract:

The oral cavity is home to a wide variety of microorganisms that lead to various diseases and even oral cancer. Despite advancements in the diagnosis and detection at the initial phase, the situation hasn’t improved much. Saliva-on-a-chip is an innovative point-of-care platform for early diagnosis of oral cancer and other oral diseases in live and dead cells using a microfluidic device with a current perspective. Some of the major challenges, like real-time imaging of the oral cancer microbes, high throughput values, obtaining a high spatiotemporal resolution, etc. were faced by the scientific community. Integrated microfluidics and microscopy provide powerful approaches to studying the dynamics of oral pathology, microbe interaction, and the oral microenvironment. Here we have developed a saliva-on-chip (salivary microbes) device to monitor the effect on oral cancer. Adhesion of cancer-causing F. nucleatum; subsp. Nucleatum and Prevotella intermedia in the device was observed. We also observed a significant reduction in the oral cancer growth rate when mortality and morbidity were induced. These results show that this approach has the potential to transform the oral cancer and early diagnosis study.

Abstract:

Carotenoids comprise a group of isoprenoid pigments. Carotenes, xanthophylls and their derivatives have been found to play an important role in all living beings through foods, neutraceuticals and pharmaceuticals. α-carotene, β-carotene and β-cryptoxanthin play a vital role in humans to provide vitamin A source for the growth, development and proper functioning of immune system and vision. They are very crucial for plants and humans as they protect from photooxidative damage and are excellent antioxidants quenching singlet molecular oxygen and peroxyl radicals. Diet including more intake of carotenoids results in reduced threat of various chronic diseases such as cancer (lung, breast, prostate, colorectal and ovarian cancers) and coronary heart diseases. The blue light filtering efficiency of the carotenoids in liposomes have been reported to be maximum in lutein followed by zeaxanthin, β-carotene and lycopene. Lycopene play a vital role for the protection from CVD. Lycopene in serum is directly related to reduced risk of osteoporosis in postmenopausal women. Carotenoids have the major role in the treatment of skin disorders. There is a need to identify and isolate novel carotenoids from diverse natural sources for human health benefits.

Abstract:

Leishmaniasis is a collection of zoonotic infections that affect the viscera, skin, and mucous membrane and are spread by several species of female sandflies in the subfamily phlebotominae. The study's goal was to assess the prevalence of Cutaneous Leishmaniasis in District Kurram using descriptive and cross-sectional methods. From December 2022 to May 2023, the study was carried out at Tehsil Head Quarter (THQ) Hospital, Sadda, District Kurram in the Dermatology Department. The disease was identified using a laboratory method based on clinical manifestations of leishmaniasis. A clean slide's surface was applied to the scraped-off portion of the lesions and rubbed over the blood to make a smear on the slide. The slides were methanol-fixed, stained with traditional Giemsa, and meticulously examined at high magnification to search for LD bodies. The necessary information, such as residence area, lesion kind and location, age, sex, and the total number of lesions, was meticulously acquired. During the time of the investigation, 393 instances of cutaneous leishmaniasis were observed. 1 year to 70 years old was the age range (mean age: 35.45). The age group that was most severely impacted, 16 years and older, had 23 (11.67%) children with this condition. Male to female ratio was 9.7:10. Most of the cases (n=52, 26.29%), were reported in the month of May. Majority of the patients 102 (51.77%) had lesion on face. 42 (16.73) patients had multiple lesions on their body. Face was the most common site followed by lower limbs 93 (37.05). Weekly intralesional injections of sodium stibogluconate (glucantime) were administered to all patients. Without any noticeable adverse effects, all patients had positive responses to the treatment. The condition affects adults more commonly than children, according to analysis of the combined results, and it is more common in women than in men.

Abstract:

Background: Dietary fat is implicated in the increasing development of chronic diseases in developing countries while dietary fibre plays a major role in the management of these diseases. Accurate nutrient composition data for composite dishes unique to a population is essential for the development of a nutrient database and the calculation of dietary intake. Methods: Representative samples of standardized Nigerian soups and dishes were analyzed for fatty acids using gas chromatography-mass spectrophotometry (GC-MS) and dietary fibre using an enzymatic-gravimetric standard method of AOAC. Results: The total Saturated Fatty acids (SFAs) ranged from 0.74+0.3g/100g to 73.82+0.07g/100g. The total monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) ranged from 2.16+1.13g/100g for Yam pottage to 22.25+0.58g/100g for Okazi soup and eba, and from 0.42+0.10g/100g for Yam pottage to 10.22+0.1g/100g for Pounded yam with egusi ball soup, respectively. Trans fat was observed in Alapafubu and Tuwo shinkafa (2.80+0.2g/100g), Yam pottage (0.20+0.15g/100g), Steamed bean pudding (1.28+0.53g/100g) and Ikokore (5.33+0.41g/100g). The Total Dietary Fibre (TDF) contents of the dishes ranged from 12.95+2.99g/100g in Jollof rice to 62.00+0.94g/100g in Melon seed and vegetable soup, the Soluble Dietary Fibre (SDF) ranged from 2.05+0.32g/100g in Steamed bean pudding to 7.81+0.74g/100g in Ikokore while the Insoluble Dietary Fibre (IDF) ranged from 8.20+0.43g/100g in Jollof rice to 57.91+4.69g/100g in melon seed and vegetable soup. Conclusions: The study has indicated that some Nigerian dishes are characterized by high SFAs, TFAs and dietary fibre, moderate MUFAs and very low levels of PUFAs. High levels of SFAs in some soups and dishes are a major public health concern.

Abstract:

Introduction: Currently, there has been an increasing concern about the provision of palliative care in non-oncological patients in both professional literature and clinical practice. However, there is not much scientific information on how to provide neurological and palliative care together. The main objective of the project is to create and to verify a concept of neuro-palliative and rehabilitative care for patients with selected neurological diseases in an advanced stage of the disease and also to evaluate bio-psychosocial and spiritual needs of these patients and their caregivers related to the quality of life using created standardized tools. Methodology: Triangulation of research methods (qualitative and quantitative) will be used. A concept of care and assessment tools will be developed by analyzing interviews and focus groups. Qualitative data will be analyzed using grounded theory. The concept of care will be tested in the context of the intervention study. Using quantitative analysis, we will assess the effect of an intervention provided on the saturation of needs, quality of life, and quality of care. A research sample will be made up of the patients with selected neurological diseases (Parkinson´s syndrome, motor neuron disease, multiple sclerosis, Huntington’s disease), together with patients´ family members. Based on the results, educational materials and a certified course for health care professionals will be created. Findings: Based on qualitative data analysis, we will propose the concept of integrated care model combining neurological, rehabilitative and specialist palliative care for patients with selected neurological diseases in different settings of care and services. Patients´ needs related to quality of life will be described by newly created and validated measuring tools before the start of intervention (application of neuro-palliative and palliative approach) and then in the time interval. Conclusion: Based on the results, educational materials and a certified course for doctors and health care professionals will be created.

Abstract:

The poor oral bioavailability of resveratrol (RSV) due to presystemic metabolism can be avoided via dermal route of administration. The hydrophilic-lipophilic nature of resveratrol-phospholipid complex (RSVPs) favors the delivery of resveratrol via the skin. The RSVPs embedded polymeric patch with moderate adhesiveness was developed for dermal application for sustained anti-inflammatory effect. The prepared patches were evaluated for various physicochemical properties, surface morphology by SEM, TEM, and compatibility of patch components by FT-IR and DSC studies. The dermal flux of the optimized patch formulation was found to be at 4.28 ± 0.48 mg/cm2/24 h. The analysis of skin extract after permeation study revealed the presence of resveratrol, which confirmed the localization of RSVPs in the skin. The stability of RSVPs in the polymeric patch and the physiologic environment was confirmed by FE-SEM studies on the patches after drug release and skin permeation studies. The RSVPs particles released from the polymer matrix maintaining the structural integrity and permeate the keratinized horney layer of skin. The optimized patch formulation showed sustained anti-inflammatory effect (84.10% inhibition of inflammation at 24 h) in carrageenan-induced rat paw edema model compared to marketed diclofenac sodium gel (39.58% inhibition of inflammation at 24 h). The CLSM study confirmed the localization of RSVPs for a longer period, thus enabling drug targeting to the dermis for sustained anti-inflammatory effect. Histological studies with phase contrast trinocular microscope suggested no alteration of skin integrity and no evidence of the presence of inflammatory cells after exposure to the permeants. The patch was found to be safe for skin application as evaluated by Draize method for skin irritation scoring in a rabbit model. These results suggest the therapeutic efficacy of the developed patch in both acute and chronic inflammatory diseases.

Abstract:

In the precision agriculture area, one of the main tasks is the automated detection of diseases in crops. Machine Learning algorithms have been studied in recent decades for such tasks in view of their potential for improving economic outcomes that automated disease detection may attain over crop fields. The latest generation of deep learning convolution neural networks has presented significant results in the area of image classification. In this way, this work has tested the implementation of an architecture of deep learning convolution neural network for the detection of diseases in different types of crops. A data augmentation strategy was used to meet the requirements of the algorithm implemented with a deep learning framework. Two test scenarios were deployed. The first scenario implemented a neural network under images extracted from a controlled environment while the second one took images both from the field and the controlled environment. The results evaluated the generalisation capacity of the neural networks in relation to the two types of images presented. Results yielded a general classification accuracy of 59% in scenario 1 and 96% in scenario 2.

Abstract:

The mechanisms underlying the association between obesity and asthma may be related to a decreased immunological tolerance induced by a defective function of regulatory T cells (Tregs). The aim of this study is to establish the potential link between these diseases and CD4+, CD25+ FoxP3+ Tregs as well as T helper cells (Ths) in children. This is a prospective case control study. Obese (n:40), asthmatic (n:40), asthmatic obese (n:40), and healthy children (n:40), who don't have any acute or chronic diseases, were included in this study. Obese children were evaluated according to WHO criteria. Asthmatic patients were chosen based on GINA criteria. Parents were asked to fill up the questionnaire. Informed consent forms were taken. Blood samples were marked with CD4+, CD25+ and FoxP3+ in order to determine Tregs and Ths by flow cytometric method. Statistical analyses were performed. p≤0.05 was chosen as meaningful threshold. Tregs exhibiting anti-inflammatory nature were significantly lower in obese (0,16%; p≤0,001), asthmatic (0,25%; p≤0,01) and asthmatic obese (0,29%; p≤0,05) groups than the control group (0,38%). Ths were counted higher in asthma group than the control (p≤0,01) and obese (p≤0,001)) groups. T cell immunity plays important roles in obesity and asthma pathogeneses. Decreased numbers of Tregs found in obese, asthmatic and asthmatic obese children may help to elucidate some questions in pathophysiology of these diseases. For HOMA-IR levels, any significant difference was not noted between control and obese groups, but statistically higher values were found for obese asthmatics. The values obtained in all groups were found to be below the critical cut off points. This finding has made the statistically significant difference observed between Tregs of obese, asthmatic, obese asthmatic, and control groups much more valuable. These findings will be useful in diagnosis and treatment of these disorders and future studies are needed. The production and propagation of Tregs may be promising in alternative asthma and obesity treatments.

Abstract:

Background: Sarcoidosis and Tuberculosis are both considered granulomatous chronic diseases with some similar pulmonary and extra-pulmonary manifestations. It is hypothesized that given these morphological similarities, the genome of mycobacterium could have an impact on the development of Sarcoidosis. Identifying the potential correlation of these diseases may assist in the management of sarcoidosis. Herein, we aimed to inspect the lymph node biopsy of sarcoidosis patients for the existence of the HSP-65 mycobacterium DNA sequence. Methods: This cross-sectional survey was conducted on 1188 Sarcoidosis patients without active/latent tuberculosis infection who were diagnosed in Masih Daneshvari Hospital in Tehran, Iran, from January 2020 to January 2022. Trans-bronchial needle aspiration (TBNA) was performed due to bilateral hilar lymphadenopathy to take a specimen. Results: The under-evaluated patients were mainly women (N=815 (68.6%)), none-smoker (N=1016 (85.5%)), and middle-aged (50.1 (SD=4.22)) with average angiotensin-converting enzyme (ACE) index of 75.6 (SD=6.42). Dyslipidemias (n=314 (26.4%), Hypertension (n=295 (24.8%)), Diabetes mellitus (n=131 (11.0%)), and chronic heart diseases (n=97 (8.2%)) had the highest prevalence between comorbidities. Skin lesions (n= 655 (55.1%)), ophthalmic (n=341 (28.7%)), and cardiac involvement (n=229 (19.3%)) were obtained as the most common extra-pulmonary characteristics of the patients. Amongst 1188 enrolled patients who were not afflicted with Mycobacterium tuberculosis based on smear/culture essay, clinical symptoms, and Chest x-ray screening, 121 (10.2%) cases had detectable amplified DNA for Mycobacterium Tuberculosis extracted from mediastinal lung lymph nodes. Conclusion: In this survey, the mycobacterium genome was detected in almost 1 per 10 case biopsies of sarcoidosis. The remarkable number of cases (n=1188) evaluated in this study was the strength of this study which supported the hypothesis regarding sarcoidosis and mycobacterium genome correlation. Further investigation, such as case-control surveys, is required to better clarify this association.

Abstract:

Based on the fact that more than 85% of the labor force and 90% of the export earnings are taken by agriculture in Ethiopia and it can be said that it is the backbone of the overall socio-economic activities in the country. Among the cereal crops that the agriculture sector provides for the country, wheat is the third-ranking one preceding teff and maize. In the present day, wheat is in higher demand related to the expansion of industries that use them as the main ingredient for their products. The local supply of wheat for these companies covers only 35 to 40% and the rest 60 to 65% percent is imported on behalf of potential customers that exhaust the country’s foreign currency reserves. The above facts show that the need for this crop in the country is too high and in reverse, the productivity of the crop is very less because of these reasons. Wheat disease is the most devastating disease that contributes a lot to this unbalance in the demand and supply status of the crop. It reduces both the yield and quality of the crop by 27% on average and up to 37% when it is severe. This study aims to detect the most frequent and degrading wheat diseases, Septoria and Leaf rust, using the most efficiently used subset of machine learning technology, deep learning. As a state of the art, a deep learning class classification technique called Convolutional Neural Network (CNN) has been used to detect diseases and has an accuracy of 99.01% is achieved.

Abstract:

Adult black flies (Diptera: Simuliidae) are small (1.5-6.0 mm long), two-winged insects, and are well known as one of the biting flies of medical and veterinary importance. Female of certain species, when they bite and take blood, not only cause severe skin diseases to human and cattle but also play a role as vectors of viral, protozoan and filarial diseases in humans and animals. Black flies also attract environmental biologist and ecologist because their immature states breed only in clean running fresh waters, and larvae are one of the principal processors of plant debris in streams. All these researches on medical and ecological aspects of black flies could not be reliably proceeded without sufficient basic knowledge of the fauna of black flies established by traditional but still important morphotaxonomy. Previously, only 39 species of black flies were recorded from Peninsular Malaysia, all of which are classified into four subgenus (Daviesellum, Gomphostilbia, Nevermannia and Simulium) of the genus Simulium. We carried out faunal surveys and taxonomic works of black flies in Peninsular Malaysia since November 2010. A total of 17 new species and 4 newly recorded species were collected. This increased the number of the described species of black flies in Peninsular Malaysia from 39 to 60. Our results suggest that a much higher diverse nature of black flies in Peninsular Malaysia will be clarified by further extensive surveys.

Abstract:

Asthma and Chronic obstructive pulmonary disease (COPD) are common lung diseases that have a significant global impact. Pressurized metered dose inhalers (pMDIs) are widely used for treatment, but they can have limitations such as high medication release speed resulting in drug deposition in the mouth or oral cavity and difficulty achieving proper synchronization with inhalation by users. Spacers are add-on devices that improve the efficiency of pMDIs by reducing the release speed and providing space for aerosol particle breakup to have finer and medically effective medication. The aim of this study is to optimize the size and cylindrical shape of spacers to enhance their drug delivery performance. The study was based on fluid dynamics theory and employed Ansys software for simulation and optimization. Results showed that optimization of the spacer's geometry greatly influenced its performance and improved drug delivery. This study provides a foundation for future research on enhancing the efficiency of inhalation therapy for lung diseases.

Abstract:

Probiotics have health-giving effects on the human body, so by stimulating the immune system, they prevent many occurrences they are diseases and food allergies in humans. There are various bacteria in the human digestive system; some are useful, some are harmless, and other groups of bacteria are harmful to human health. These bacteria should be in balance in the body of people in a normal state. In certain conditions, such as a person's high stress, aging, continuous use of antibiotics, or improper diet, the intestinal microbial flora has changed, and these changes cause some diseases in people. Probiotics have health benefits for the human body and are often found in the digestive system of healthy people. Nevertheless, fermented foods such as fermented dairy products such as yogurt, cheese, buttermilk or fermented pickles contain some species of these bacteria that are useful. But the important point that should be noted is that due to modern and industrial life, high fat and high protein diets, and excessive use of antibiotics, the number of these bacteria in people's bodies has decreased, and it is necessary to consume probiotics either in the form of probiotic foods or in the form of supplements. Probiotics with mild stimulation of the immune system increase the immunity level of the body and prevent the occurrence of food allergies in people.

Abstract:

A six-point-two-magnitude earthquake rocked Mamuju District, West Sulawesi Province, Indonesia, on 15 January 2021, causing significant health issues for the affected community, particularly among vulnerable populations such as neonates and children. The aim of this study is to examine and describe the diseases diagnosed in the pediatric population in Mamuju 14 days after the earthquake. This study uses a prospective observational study of the pediatric population presenting at West Sulawesi Regional Hospital, Mamuju Regional Public Hospital, and Bhayangkara Hospital for the period of 14 days after the earthquake. Demographic and clinical information were recorded. One hundred and fifty-three children were admitted to the health center. Children younger than six years old were the highest proportion (78%). Out of 153 children, 82 of them were male (54%). The most frequently diagnosed disease during the first and second weeks after the earthquake was respiratory problems, followed by gastrointestinal problems that showed an increase in incidence in the second week. This study found that age has a correlation with frequent disease in children after an earthquake. Respiratory and gastrointestinal problems were found to be the most common diseases among the pediatric population in Mamuju after the earthquake.

Abstract:

In December 2019, a coronavirus, currently identified as SARS-CoV-2, produced a series of acute atypical respiratory illnesses in Wuhan, Hubei Province, China. The sickness induced by this virus was named COVID-19. The virus is transmittable between humans and has caused pandemics worldwide. The number of death tolls continues to climb and a huge number of countries have been obliged to perform social isolation and lockdown. Lack of focused therapy continues to be a problem. Epidemiological research showed that senior patients were more susceptible to severe diseases, whereas children tend to have milder symptoms. In this study, we focus on other possible side effects of COVID-19 and more detailed treatment strategies. Using bioinformatics analysis, we first isolated the gene expression profile of patients with severe COVID-19 from the GEO database. Patients' blood samples were used in the GSE183071 dataset. We then categorized the genes with high and low expression. In the next step, we uploaded the genes separately to the Enrichr database and evaluated our data for signs and symptoms as well as related medication regimens. The results showed that 138 genes with high expression and 108 genes with low expression were observed differentially in the severe COVID-19 VS control group. Symptoms and diseases such as embolism and thrombosis of the abdominal aorta, ankylosing spondylitis, suicidal ideation or attempt, regional enteritis were observed in genes with high expression and in genes with low expression of acute and subacute forms of ischemic heart, CNS infection and poliomyelitis, synovitis and tenosynovitis. Following the detection of diseases and possible signs and symptoms, Carmustine, Bithionol, Leflunomide were evaluated more significantly for high-expression genes and Chlorambucil, Ifosfamide, Hydroxyurea, Bisphenol for low-expression genes. In general, examining the different and invisible aspects of COVID-19 and identifying possible treatments can help us significantly in the emergency and hospitalization of patients.

Abstract:

Numerous mushroom bioactive metabolites, including polysaccharides, eritadenine, lignin, chitosan, mevinolin, and astrakurkurone have been studied in life-threatening conditions and diseases such as diabetes, cardiovascular, hypertension, cancer, DNA damage, hypercholesterolemia, and obesity attempting to identify natural therapies. These bioactive metabolites have shown potential as antiviral and immune system strengthener natural agents through diverse cellular and physiological pathways modulation with no toxicity evidence, widely available, and affordable. In light of the emerging literature, this paper compiles the most recent information describing the molecular mechanisms that underlie the nutraceutical potentials of these mushroom metabolites suggesting their effectiveness if combined with existing drug therapies. The findings raise hope that these mushroom bioactive metabolites may be utilized as natural therapies considering their therapeutic potential while anticipating further research designing clinical trials and developing new drug therapies while encouraging their consumption as a natural adjuvant in preventing and controlling life-threatening conditions and diseases.

Abstract:

Corneal diseases are one of the main causes of visual impairment and affect almost 4 million, and this study assesses the effects of deep anterior lamellar keratoplasty (DALK) with porcine corneal stroma and postoperative topical treatment with tacrolimus in patients with infectious keratitis. No patient was observed with clinical graft rejection. Among the cases: 2 were positive to fungal culture, 2 with Aspergillus and the other 8 cases were confirmed by bacteriological culture. Corneal diseases are one of the main causes of visual impairment and affect almost 4 million. This study assesses the effects of deep anterior lamellar keratoplasty (DALK) with porcine corneal stroma and postoperative topical treatment with tacrolimus in patients with infectious keratitis. Receiver bed diameters ranged from 7.00 to 9.00 mm. No incidents of Descemet's membrane perforation were observed during surgery. During the follow-up period, no corneal graft splitting, IOP increase, or intolerance to tacrolimus were observed. Deep anterior lamellar keratoplasty seems to be the best option to avoid xenograft rejection, and it could help new surgical techniques in humans.

Abstract:

Plasma-derived medicinal products are vital categories of biological therapies. These products are used to treat rare, chronic, severe, and life-threatening conditions, such as bleeding disorders (Hemophilia A and B), hemolytic disease of the fetus and newborn, severe infections, burns and liver diseases, and other diseases caused by the absence or malfunction of certain proteins. In addition, they improve the patient’s quality of life. The process of producing plasma-derived medicinal products begins with the collection of human plasma from healthy donors. This initial stage is complex and is monitored with high precision and sensitivity by global authorities to maintain the quality and safety of the final products as well as the health of the donors. The amount of manufactured plasma-derived medicinal products depends on the availability of its raw material, human plasma, so collecting enough plasma for fractionation is essential. Therefore, adopting a suitable national policy regarding plasma donation, establishing collection centers, and increasing public awareness of the importance of plasma donation will improve any country’s conditions regarding the timely and sufficient supply of these medicines. In this study, we tried to briefly examine the importance of sustainability of the plasma industry and its situation in our beloved country of Iran.

Abstract:

Despite an increase in the number of cancer programs and partnerships in cancer care provision, the burden of cancer in Zambia is increasingly having a significant impact on morbidity and mortality rates. The increase in cancer morbidity and mortality rates has given rise to psychological and psycho social implications (PPsI) in cancer care. Cancer patients, care givers and health care providers are faced with a multitude of PPsIs in cancer care that mainly impact negatively on the management of cancer patients. The study adopted a case study design and was purposively conducted at the Cancer Diseases Hospital in Lusaka (Zambia) after obtaining ethical clearance from the Ethics committee. The sample for this study included 70 cancer patients, 20 care givers and 5 hospital staff (4 nurses and 1 doctor). Data was collected using interviews guides, focus group discussion guides and questionnaires respectively. The qualitative data was analysed thematically. The various psychological and psychosocial challenges that conspire to deter the provision of effective cancer care nursing and improved methods of minimizing the psychological and psychosocial implications in cancer care are the products of this study.

Abstract:

Birth defects are morphological abnormalities and functionally represent the main causes of morbidity and neonatal mortality. The aim was to analyze a number of maternal and newborn traits, assess the main causes and risk factors of abnormalities and describe the clinical aspects and different types of birth defects at the maternity of Batna. Our rate of congenital malformations is 19% of hospitalized newborns; mono malformations are the most common, mainly 28% neurological malformations predominated by Spina Bifida and hydrocephalus. Poly malformations accounted for only 15% of our study. 39,61% of newborns are premature. We found a male predominance. The sex ratio is 1.33 male to one girl, most by mothers over 35. The analysis of the pathological history has shown that the diseases encountered in mothers are pregnant HTA and diabetes, these are the most common diseases with a percentage of (19%, and 21%). The percentage of people who use medicine is 28%. In terms of diagnosis, prenatal ultrasounds are performed in 12% of cases, and the death rate is often fairly high at 45%. Congenital malformations remain a problem in terms of treatment and prognosis; this will make it possible to investigate other factors, to better understand the causes of congenital malformations and to develop effective prevention and treatment strategies.

Abstract:

Objectives: The purpose of this paper is to investigate the social policy of preventive genetic medicine in Iran, by following the legalization process of abortion law and the factors affecting the process in wider Iranian contexts. In this paper, ethical discussions of prenatal diagnosis and selective abortion in Iran will be presented, by exploring Iranian social policy to control genetic diseases, especially a genetic hemoglobin disorder called Thalassemia. The ethical dilemmas in application of genetic medicine into social policy will be focused. Method: In order to examine the role of the policy for prevention of genetic diseases and selective abortion in Iran, various resources have been sutudied, not only academic articles, but also discussion in the Parliament and documents related to a court case, as well as ethnographic data on living situation of Thalassemia patients. Results: Firstly, the discussion on prenatal diagnosis and selective abortion is overviewed from the viewpoints of ethics, disability rights activists, and public policy for lower-resources countries. As a result, it should be noted that the point more important in the discussion on prenatal diagnosis and selective abortion in Iran is the allocation of medical resources. Secondly, the process of implementation of national thalassemia screening program and legalization of ‘Therapeutic Abortion Law’ is analyzed, through scrutinizing documents such as the Majlis record, government documents and related laws and regulations. Although some western academics accuse that Iranian policy of selective abortion seems to be akin to eugenic public policy, Iranian government carefully avoid to distortions of the policy as ‘eugenic’. Thirdly, as a comparative example, discussions on an Iranian court case of patient’s ‘right not to be born’ will be introduced. Along with that, restrictive living environments of people with Thalassemia patients and the carriers are depicted, to understand some disabling social factors for people with genetic diseases in the local contexts of Iran.

Abstract:

Accurate segmentation of the optic disc is very important for computer-aided diagnosis of several ocular diseases such as glaucoma, diabetic retinopathy, and hypertensive retinopathy. The paper presents an accurate and fast optic disc detection and segmentation method using an attention based fully convolutional network. The network is trained from scratch using the fundus images of extended MESSIDOR database and the trained model is used for segmentation of optic disc. The false positives are removed based on morphological operation and shape features. The result is evaluated using three-fold cross-validation on six public fundus image databases such as DIARETDB0, DIARETDB1, DRIVE, AV-INSPIRE, CHASE DB1 and MESSIDOR. The attention based fully convolutional network is robust and effective for detection and segmentation of optic disc in the images affected by diabetic retinopathy and it outperforms existing techniques.

Abstract:

Cardiovascular disease is the cause of the highest mortality rates in the world. The number of cardiovascular disease patients is increasing every year. Data obtained from World Health Organization (WHO) that 17,5 million people died from this disease. The condition of cardiovascular diseases such as atrial fibrillation, myocardial infarction, venous thromboembolism, and several other conditions need anticoagulant therapy. Results of the anticoagulant therapy are measured not only by the effectiveness of International Normalized Ratio (INR) value but also by the quality of life of the patients. The purpose of this study was to determine the quality of life of patients on oral anticoagulant therapy in outpatient cardiac department Dr. Hasan Sadikin central general hospital, Bandung, Indonesia. This is a cross-sectional study with collecting data from the quality of life questionnaire and medical record of the patients. The results of this study showed that 28 patients (46,7%) had a good quality of life, 30 patients (50%) had a moderate quality of life, and 2 patients (3,3%) had a poor quality of life with no significant differences in quality of life based on age, gender, diagnosis, and duration of drug use.

Abstract:

In the last few years, due to the misuse of antibiotics and an increasing incidence of immunodeficiency-related diseases, the development of microbial drug resistance has become more and more of a pressing problem. Recently, natural products from medicinal plants represent a fertile ground for the development of novel antibacterial agents. Plants essential oils have come more into the focus of phytomedicine. The present study describes antimicrobial activity of Rosmarinus officinalis L. essential oil known medicinally for its powerful antibacterial properties. The essential oil of rosemary obtained by hydrodistillation (using Clevenger type apparatus) growing in Algeria (Djelfa city of south Algeria) was investigated by GC-MS. The essential oil yield of the study was 1.4 %. The major components were found to be camphor, camphene, 1,8-cineole. The essential oil has been tested for antimicrobial activity against eight bacteria (Gram-negative and Gram-positive), and three fungi including Candida albicans. Inhibition of growth was tested by the agar diffusion method based on the determination of the diameter of inhibition. The oil was found to have significant antibacterial activity and therefore can be used as a natural antimicrobial agent for the treatment of several infectious diseases caused by those germs, which have developed resistance to antibiotics.

Abstract:

The efficacy of Defender 2% WS (tebuconazole) and Imidal 70 WS (imidacloprid) to control damping-off diseases and early insect pests in sesame crop under rain fed conditions at Damazine and Gedarif areas was evaluated. Defender 2% WS with dosage rates 0.5, 0.75, 1.0 and 1.25 g/kg of seeds and Imidal 70 WS at 2.25, 3.0, and 3.75 g/ kg of seeds were tested singly and as a mixture during 2010/2011 and 2012/013. Sesame seeds treated with Defender at the rates of 0.5 g and 0.75 g/ kg of seeds gave a high significant increase in percent seedlings emergence (84% and 85%) respectively. Imidal 70 WS at rate of 3g/kg seed showed the least percent damaged leaves by sesame webworm (1.7%). However, the mixed Defender at rate 0.75g with Imidal at 3 g/kg seed, significantly gave a highest percentage of sesame seedling emergence (85.1%) and reduced the incidence of post-emergence damping off and percent damaged leaves to the least per cent (2.1% and 0.4% ) respectively, compared to other treatments. Consequently, the mixed treatment of 0.75 g of Defender + 3 g of Imidal improved the crop stand and significantly gave the highest yield (405.2 kg and 418.8 kg/fed) respectively in both sites compared to the other treatments.
