First-time detection of Mycobacterium bovis in livestock tissues and milk in the West Bank, Palestinian Territories.

ABSTRACT:

Background

Bovine tuberculosis, bTB, is classified by the WHO as one of the seven neglected zoonontic diseases that cause animal health problems and has high potential to infect humans. In the West Bank, bTB was not studied among animals and the prevalence of human tuberculosis caused by M. bovis is unknown. Therefore, the aim of this study was to estimate the prevalence of bTB among cattle and goats and identify the molecular characteristics of bTB in our area.

Methodology/principal findings

A total of 208 tissue samples, representing 104 animals, and 150 raw milk samples, obtained from cows and goats were examined for the presence of mycobacteria. The tissue samples were collected during routine meat inspection from the Jericho abattoir. DNA was extracted from all samples, milk and tissue biopsies (n = 358), and screened for presence of TB DNA by amplifying a 123-bp segment of the insertion sequence IS6110. Eight out of 254 animals (3.1%) were found to be TB positive based on the IS6110-PCR. Identification of M. bovis among the positive TB samples was carried out via real time PCR followed by high resolution melt curve analysis, targeting the A/G transition along the oxyR gene. Spoligotyping analysis revealed a new genotype of M. bovis that was revealed from one tissue sample.

Significance

Detection of M. bovis in tissue and milk of livestock suggests that apparently healthy cattle and goats are a potential source of infection of bTB and may pose a risk to public health. Hence, appropriate measures including meat inspection at abattoirs in the region are required together with promotion of a health campaign emphasizing the importance of drinking pasteurized milk. In addition, further studies are essential at the farm level to determine the exact prevalence of bTB in goats and cattle herds in the West Bank and Israel.

Project description:Adequate patient knowledge about medications is essential for appropriate drug taking behavior and patient adherence. This study aims to assess and quantify the level of knowledge and adherence to medications among Palestinian geriatrics living with chronic diseases and to investigate possible associated socio-demographic characteristics.We conducted a cross-sectional study during June 2013 and January 2014 among Palestinian geriatrics ≥ 60 years old living with chronic disease in the West Bank and East Jerusalem. A stratified random sample was selected and a questionnaire-assisted interview was applied for data collection. T-test was applied for bivariate analyzing and one-way ANOVA test was applied for multivariate analyses.A total of 1192 Palestinian geriatrics were studied. The average age was 70.3 (SD = 8.58) years and ranged from 60-110 years. The sample comprised 659 (55.3%) females and 533 (44.7%) males. The global knowledge and global adherence scores were (67.57%) and (89.29%), respectively. Adequate levels of knowledge were 71.4%, and of adherence 75%, which were recorded for 705 (59.1%) and 1088 (91.3%) participants, respectively. Significant higher levels of global knowledge and global adherence were recorded for males, and for participants who hold a Bachelor's degree, those who live on their own, and did physical activity for more than 40 hours/week (p-value < 0.05). Furthermore, workers, participants with a higher monthly income, and non-smokers have a higher knowledge level with (p-value < 0.05). We found positive correlation between participants' global adherence and global knowledge (r = 0.487 and p-value < 0.001). Negative correlation was found between participants' global knowledge and adherence with age (r = -0.236, p-value < 0.001 and r = -0.211 and p-value < 0.001, respectively. Negative correlation between global knowledge and the number of drugs taken (r = -0.130, p-value < 0.001) was predicted.We concluded that patients with a higher level of knowledge are more adherent to their medications and that better understanding of socio-demographic factors has a clear influence on the level of knowledge and adherence to medications and thus contributes to the development of guidelines for treatment and may consequently lead to favourable clinical outcomes and savings of health care costs.

Project description:ObjectiveWe investigated some aspects of menstrual health and hygiene among young female students at Birzeit University in the West Bank of the occupied Palestinian territory.DesignCross-sectional study in a large central university.ParticipantsOut of a total of 8473 eligible female students, a calculated sample size of 400 students aged between 16 and 27 years was obtained.SettingLarge central university, West Bank, occupied Palestinian territory (oPt).MeasuresAn anonymous structured international research instrument consisting of 39 questions based on the Menstrual Health Questionnaire, in addition to few questions relevant to the context, was administered.Results30.5% of participants were not informed about menstruation before menarche, and 65.3% reported that they were not ready when they got their first period. The highest reported source of information regarding menstruation was family (74.1%), followed by school (69.3%). About 66% of respondents reported that they need more information on various topics of menstruation. The most common type of menstrual hygiene products used were single-use pads (86%), followed by toilet paper (13%), nappies (10%) and reusable cloths (6%). Of the total 400 students, 14.5% reported that menstrual hygiene products are expensive, and 15.3% reported that they always/sometimes had to use menstrual products that they do not like because they are cheaper. Most (71.9%) of the respondents reported that they used menstrual products for longer time than recommended due to inadequate washing facilities at the university campus.ConclusionsThe findings provide useful evidence on the lack and the need for menstrual-related information for female university students, inadequate infrastructure to help them manage their menstruation with dignity and pointed to some menstrual poverty in accessing menstrual products. A national intervention programme is needed to increase awareness regarding menstrual health and hygiene among women in local communities and female teachers in schools and universities to enable them to disseminate information to and meet the practical needs of girls at home, at school and at the university.

Project description:BackgroundThe Covid-19 pandemic created major global health crises, with serious effects on all aspects of life. The pandemic reached the Israeli occupied West Bank of Palestine in early March 2020, and lockdown immediately ensued.ObjectivesTo assess the prevalence and predictors of distress and insecurity among Birzeit University's community during the COVID-19 pandemic and lockdown.MethodsAn online survey completed in March-April 2020 using standardized and previously validated distress and insecurity scales. The survey was placed on the University portal accessed by students, faculty and employees, and was sent by email to faculty and employees. Data were weighted to reflect the University community's distribution.FindingsThere were 1,851 participants in the study: 84% were undergraduate students, 10% graduate students, and 6% faculty and employees. Sixty two percent were women. Ages ranged from 17 to 70 years (mean 24 ± 9.7). Prevalence of moderate/high distress and insecurity were 40% and 48% respectively. Multiple logistic regression revealed that women, those under 35 years old and those with worse reported income, had significantly higher odds of distress and insecurity compared to their counterparts. Undergraduate students or living with a person at home with high risk of illness with COVID-19 were associated with higher odds of distress compared to their counterparts (OR = 1.56, 95%CI[1.13-2.15]) and (OR = 1.34, 95%CI[1.11-1.62]) respectively. A COVID-19 worry score was significantly associated with higher odds of distress and insecurity (OR = 1.77, 95%CI[1.46-2.14]) and (OR = 4.3, 95%CI[3.53-5.23]) respectively.ConclusionThis study emphasizes the need to pay attention not only to physical health but also to mental health during the COVID-19 pandemic, especially among young people, women, those with lower economic status, and those living with high risk persons during the pandemic. We hope that this study will inform the policies and interventions of the Palestinian Authority, local non-governmental organization, international groups working in the occupied Palestinian territory, and beyond.

Project description:The United States official bovine tuberculosis (bTB) eradication program has utilized genotyping for Mycobacterium bovis isolates since 2000 and whole genome sequencing was implemented in 2013. The program has been highly successful, yet as bTB prevalence has reached historic lows, a small number of new bTB-affected cattle herds occur annually. Therefore, understanding the epidemiology of bTB transmission is critically important, in order to target limited resources for surveillance and achieve eradication. This evaluation described the diversity and epidemiology of M. bovis isolates identified in the USA livestock. Isolates from animals within the bTB endemic area of Michigan were excluded. Broad diversity was found among 1,248 isolates, collected from affected cattle and farmed cervids herds and fed cattle during 1989-2018. Nearly 70% of isolates from 109 herds/cases during 1999-2018 were European clonal complex 1 and 30% were European clonal complex 2. The sources of infection based on the herd investigation were known for 41% of herds/cases and 59% were not epidemiologically linked to another USA origin herd. Whole genome sequencing results were consistent with the investigation findings and previously unrecognized links between herds and cases were disclosed. For herds/cases with an unknown source of infection, WGS results suggested several possible sources, including undocumented cattle movement, imported cattle and humans. The use of WGS in new cases has reduced the time and costs associated with epidemiological investigations. Within herd SNP diversity was evaluated by examining 18 herds with 10 or more isolates sequenced. Forty percent of isolates had not diverged or accumulated any SNPs, and 86% of the isolates had accumulated 3 or fewer SNPs. The results of WGS does not support a bTB reservoir in USA cattle. The bTB eradication program appears to be highly effective as the majority of herds/cases in the USA are unique strains with limited herd to herd transmission.
