Background: Studies on mice and aging human hair follicles provide compelling evidence that graying of hair results from premature differentiation of Melanocyte stem cells (MeSC) in the niche/bulge. Objective:  To analyze whether differentiation of melanocyte stem cells is responsible for premature graying of hair (PGH). Methods:  Twenty- five patients of PGH (n=25) attending dermatology department were recruited. Five unpigmented and five pigmented hairs were obtained per patient by separating individual follicles by 1 mm punch biopsies. The hairs were dissected at a distance of 2 mm from the bulb to separate the stem cells (upper segment) (US) from the melanocytes (lower segment) (LS). RNA was extracted from hair follicle segments US and LS, and expression of GP100, Tyrosinase (TYR) and Tyrosinase related protein-1 (TYRP1) genes was quantified using Qiagen one-step RT-PCR kit. Results:  We found melanogenesis gene expression in both temporary (US) and permanent (LS) segments of unpigmented and pigmented hair follicles. When compared between the US and LS of white hair, the expression of TYR and GP100 was much higher in US than LS, suggestive of melanogenesis in the bulge. Similarly, when compared between white and black US, the expression of all three genes was higher in white US than black US, although not statistically significant. Limitations: Low samples size and lack of data pertaining to the expression of genes at protein level are the limitations of current study. Conclusion: Even though this pilot study data yielded key information about the expression of GP100, TYR and TYRP-1 at mRNA level, further studies quantifying the expression of these genes at protein level are needed to provide additional clues to further address the results in detail.

Background: Future health-care professionals face stress both during education and in later professional life. Next to educational trainings, many students are forced to assume part-time employment. Objective: Applying the Job Demands-Resources Model to the educational context, we investigate which role part-time employment plays next to health-care professional students’ education-specific demands and resources in the prediction of perceived stress. Method: In this cross-sectional study, data from N = 161 health-care students were analysed, testing moderation models. Results: Education-specific demands were associated with higher and education-specific resources with lower amounts of perceived stress. Part-time employment functioned as moderator, i.e. demands were less associated with stress experiences in students who were employed part-time. Conclusion: Identifying part-time employment as a resource rather than a demand illustrates the need to understand students’ individual influences on stress. Both educators and students will benefit from reflecting these resources to support students’ stress management.

Background: The global advocacy for Direct Access (DA) and Patients’ Self-Referral (PSR) to physiotherapy is consistent with the quest for promoting professional autonomy and recognition. It was hypothesized in this study that the attainment of this clarion call in Nigeria may be hamstrung by challenges similar or different from those reported in other climes. Objective: This study assessed the perception of DA and PSR among Physiotherapists (PTs) in South-West, Nigeria. Methods: One hundred PTs from ten purposely selected public-funded out-patient facilities from South-West, Nigeria responded in this cross-sectional study, yielding a response rate of 75% (100/150).  A previously validated questionnaire for World Confederation of Physical Therapists (WCPT) on the global view of DA and PSR for physical therapy was used in this study. Data was analyzed using descriptive statistics. Results: There was a high awareness on legislation regulating practice (91%) and scope (84%) of the profession. Respondents assert that the extant legislation allows for DA (49%) and PSR (97%). However, 40% of the respondents opined that the baccalaureate qualification of PTs was inadequate for competence in DA and PSR; and a post-professional residency programme was mostly recommended (52%). Public support for DA and PSR to physiotherapy was rated more than the advocacy role of the Nigeria Society of Physiotherapy (60% vs. 40%). Physicians’ (71%) and politicians’ (65%) views were rated the major barrier to achieving DA and PSR status in physiotherapy. Similarly, physicians’ (90%) and politicians’ (88%) support was perceived as the major facilitator.  Conclusion: Physiotherapy practice in Nigeria has the semblance of autonomy in DA and PSR but is devoid of legislative support. Most Nigerian physiotherapists assume professional autonomy but were not aware of the lack of legal support for DA and PSR. The current entry-level academic curricula were considered to be deficient and inadequate for autonomous practice in Nigeria.  Physicians and politicians were the most important barrier or facilitator to achieving legal support for DA and PSR in physiotherapy in Nigeria.

Background: Oral hygiene behaviours as well as dietary habits before bed can affect children’s dental health resulting in higher prevalence of dental disease. Dental disease can affect children’s health, development and even school performance. If left untreated, dental disease can progress and it can lead to extractions under general anaesthetic causing further distress for children and families. Consistent and appropriate oral hygiene behaviours and dietary habits can prevent dental diseases from occurring in the first place. Objective: This cross-sectional study examines the relationship between oral hygiene behaviours, dietary habits around bedtime and children’s dental health. Methods: A total of 185 parents with children between the ages of 3 and 7 years from deprived areas participated in the study. Data on bedtime routine activities were collected using an automated text-survey system. Children’s dental health status was established through examination of dental charts and dmft (decayed, missed, filled teeth) scores. Results: In total, 52.4% of parents reported that their children’s teeth were brushed every night. The majority of children (58.9%) had dmft scores over zero. In total, 51 (46.7% of children with dmft score over 0 and 27.5% of all children) children had active decay. The mean dmft score for those experiencing decay was 2.96 (SD = 2.22) with an overall mean dmft score of 1.75 (SD = 2.24). There were significant correlations between frequency of tooth brushing, frequency of snacks/drinks before bed and dmft scores (r = −0.584, p < 0.001 and r = 0.547, p = 0.001 respectively). Finally, higher brushing frequency was associated with a lower likelihood of a dmft score greater than 0 (Exp(B) = 0.9). Conclusions: Despite families implementing oral hygiene behaviours as part of their bedtime routines those behaviours varied in their consistency. Results of this study highlight the need for additional studies that consider bedtime routine-related activities and especially the combined effects of oral hygiene practices and dietary habits due to their potentially important relationship with children’s dental health.

Background Most older adults with comorbidities in primary care clinics use multiple medications and are at risk of potentially inappropriate medications (PIMs) prescription. Objective This study examined the prevalence of polypharmacy and PIMs using Thai criteria for PIMs. Methods This study was a retrospective cross-sectional study. Data were collected from electronic medical records in a primary care clinic in 2018. Samples were patients aged ≥65 years old with at least 1 prescription. Variables included age, gender, comorbidities, and medications. The list of risk drugs for Thai elderly version 2 was the criteria for PIMs. The prevalence of polypharmacy and PIMs were calculated, and multiple logistic regression was conducted to examine associations between variables and PIMs. Results Of 2806 patients, 27.5% and 43.7% used ≥5 medications and PIMs, respectively. Of 10 290 prescriptions, 47% had at least 1 PIM. The top 3 PIMs were anticholinergics, proton-pump inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs). Polypharmacy and dyspepsia were associated with PIM prescriptions (adjusted odds ratio 2.48 [95% confident interval or 95% CI 2.07-2.96] and 3.88 [95% CI 2.65-5.68], respectively). Conclusion Prescriptions with PIMs were high in the primary care clinic. Describing unnecessary medications is crucial to prevent negative health outcomes from PIMs. Computer-based clinical decision support, pharmacy-led interventions, and patient-specific drug recommendations are promising interventions to reduce PIMs in a primary care setting.

Maternal breastfeeding is associated with multiple health benefits, both for the child and the mother. Since breastfeeding rates are declining, finding new, future-oriented strategies to strengthen and support mothers’ positive attitudes towards breastfeeding need to be developed. In this paper, we describe how information about the presence of stem cells in breast milk can influence the willingness to breastfeed in the population of Polish pregnant women. A cross-sectional study involving a group of 150 pregnant women was conducted to assess the correlation between their knowledge about stem cells and their attitude towards breastfeeding. Among the respondents, only 6% claimed that they did not know anything about stem cells, but general knowledge about stem cells in the research group was poor. The survey results indicated that city residence, university degree, maternal experience and advanced pregnancy correlated with higher general knowledge regarding stem cells. Most respondents (77.3%) had no knowledge regarding the presence of stem cells in breast milk. Approximately two-thirds of mothers with earlier negative breastfeeding experience declared that information about the presence of stem cells in breast milk could have influenced the decision to continue and extend the time of breastfeeding. Hence highlighting the presence of stem cells in breast milk can be used to encourage breastfeeding as a unique activity.

Introduction: Conjunctivitis is a common health problem in Nepal. It is inflammation of conjunctiva presenting as red eye. It is a communicable eye disease. Health education to the students and proper management can help spread of the disease. Knowledge of conjunctivitis among school students will help in prevention of the disease. So the study was carried out to assess the knowledge of conjunctivitis among high school students in Pokhara valley of Western Nepal. Materials/ Methods: A school based cross sectional study was performed among six government schools in western Nepal from May 2019 to June 2019. Students from grade eight, nine and ten were included in the study. Data was collected using structured questionnaire including demographic data, knowledge regarding sign symptoms of conjunctivitis, treatment, prevention, complication of conjunctivitis. Data was analysed using SPSS version 11.6. Result: A total of 523 students were included in the study. The mean age of the students was 14.7 ± 1.2 years with majority of females (53%). Nearly 2/3rd of the students (61.6%) had heard of conjunctivitis. Majority of the students (87.4%) of the students mentioned that it is communicable while 80.3% of the students correctly mentioned its etiology. Majority of the students (97.9%) mentioned that it is curable with treatment as first option (97.5%). Majority of the students (98.3%) correctly responded to the preventive measures but majority of the students (83.2%) wrongly mentioned mode of transmission. Conclusion: Secondary school students in Western Nepal have poor knowledge of conjunctivitis. Appropriate eye health education should be given to school students to prevent rapid spread of infective conjunctivitis.

OBJECTIVES: The objective of this study was to compare working length calculated with conventional radiographs and an electronic apex locator (IPEX II) during the root canal treatment of mandibular anterior teeth. METHODOLOGY: A cross-sectional study was done in the Department of Operative Dentistry, Sardar Begum Dental Hospital, Peshawar during February and March 2018. A consecutive sampling technique was used for sampling. Only 30 patients fulfilled the inclusion criteria of our study. Detailed medical and dental history was taken. Only patient fulfilling inclusion criteria were enrolled in the study. Data were analyzed using SPSS version 20. RESULTS: The mean age for patients was 45.33±5.16. 33% out of 30 patients (10) were male and 20 were females. The mean working length calculated from radiographs was 22.25±1.29 (min 20.09-max 24.10). The mean working length calculated by the electronic apex locator (IPEX II) was 22.17±1.28 (min 20.00-max 24.07). The mean difference between working length calculated by radiograph and electronic apex locator was -0.084mm, which means the working length determined by radiographs and by electronic apex locator has no difference in mandibular anterior teeth with single canals. CONCLUSION: Both the methods can be used effectively in endodontics for single-rooted mandibular teeth, but if both are used in combinations can lead to an improvement in the working length accuracy, which may significantly reduce the number of radiographs exposure, and increase the success and comfort for endodontic patients. KEYWORDS: Working Length, Apex Locator, Conventional Radiograph

Background: Several risk factors have been identified for postpartum hemorrhage, one of which being the duration of the third stage of labour. This stage refers to the interval between the expulsion of the fetus to the expulsion of the placenta. Some bleeding occurs in this stage due to the separation of the placenta Objective: This study aimed to identify the factors associated with the length of the third stage of labour. Methods: In this cross-sectional study, 300 women hospitalized for vaginal birth were selected via convenience sampling. The study data were collected using a researcher-made questionnaire. Then, the data were analyzed using univariate and multivariate linear regression analyses. Results: The mean (SD) age of the participants was 26.41 (6.26) years. Investigation of the relationship between the study variables and the time of placental separation indicated that a minute increase in the length of membranes rupture caused a 0.003minute decrease in the time of placental separation. However, this time increased by 2.75, 6.68, and 2.86 minutes in the individuals without the history of abortion, those with the history of stillbirth, and those who had not received hyoscine, respectively. The results of multivariate analysis indicated that suffering from preeclampsia or hypertension, history of stillbirth, not receiving hyoscine, and not receiving misoprostol increased the length of the third stage by 4.40, 8.55, 2.38, and 6.04 minutes, respectively. Conclusion: Suffering from preeclampsia and having the history of stillbirth increased and using hyoscine and misoprostol decreased the length of the third stage of labour. However, no significant relationship was found between the length of the third stage of labour and mother’s age, gestational age, parity, mother’s body mass index, mother’s chronic disorders, history of manual placenta removal, length of the first and second stages, membranes rupture, induction, amount of oxytocin after delivery, and infant’s weight and gender.

Abstract Objectives One Health approach to health considers human, animal, and ecosystem health as a whole and advocates cooperation across disciplines to reach the highest level of health. The aim of the study is to determine the attitudes of the medical interns’ toward the One Health approach and to evaluate related factors. Methods This cross-sectional study targeted all interns of the Faculty of Medicine of 2019–2020 academic year (n=356). Sociodemographic characteristics, health status, habits, and attitudes toward One Health were asked in the questionnaire, which was created by the researchers using the literature. The study data were collected based on self-report during occupational health and safety training, before the COVID-19 pandemic. Chi-square and logistic regression analyses were also performed. Results The study group included a fair gender distribution (47.8% female), and the average age was 23.6 ± 1.2. Out of the 316 participants, 40.2% had not heard the One Health concept before. In total, 85.4% of them declared a positive attitude toward the concept. The probability of high attitude was found to be 5.03 times (95% CI 1.10–23.12) higher in those with above-average success status and 4.08 times (95% CI 1.15–14.52) higher in those who had kept animals. In students’ responses to the attitude questionnaire items, the epidemic sub-dimension had the highest level as 86.1%, and the antibiotic resistance sub-dimension had the lowest level as 77.2%. Conclusions The current study revealed that the awareness on One Health concept among medical interns is limited, however, students’ attitudes are positive. Recent SARS-CoV 2 pandemic showed us the urgent need for proper implementation of’ One Health approach in the medical education curriculum. Meanwhile, One Health focused courses should be introduced into the curriculum of final year medicine and related programs.

Introduction: The primary attachment figure is mostly defined as the mother, and studies focus on the mother. However, in many babies, basic attachment is just as good with the father as with the mother. It is seen that there are very few studies in the literature investigating the correlations of father-infant attachment relationships.. The aim of this study is to determine the father-infant attachment status and to determine the factors affecting attachment. Method: The population of the cross-sectional study consisted of the spouses of all puerperant women hospitalized in the Gynecology and Obstetrics Clinic between September 1, 2018 and October 1, 2018. The sample size consisted of 156 fathers who agreed to participate in the study. Father identification form and father-infant attachment scale were used to collect the study data. The analysis of the data obtained from the research was carried out on the computer using the SPSS 16.0 package program. Results: 156 fathers participated in the study. The mean age of the fathers is 33.64±6.49, and 38.5% of them have a bachelor's degree. 91.0% of fathers stated that they felt ready for fatherhood. The fathers' Father-Infant Attachment Scale mean score was 82.60±7.72 In the analysis, the difference between the variables and the total score of the scale was found to be statistically insignificant (p>0.05). Discussion and Conclusion: At the end of the study, the bonding process of fathers participating in the study with their babies and the factors affecting this process were evaluated and it was seen that the father-infant attachment scale mean scores of the fathers participating in the study were high and were similar to other studies. In addition, when the basic factors affecting father-infant attachment were compared with the attachment scale mean score, it was found that there was no statistically significant difference.
