Prevalence and characteristics of Palestine refugee mothers at risk of postpartum depression in Amman, Jordan: a cross-sectional study.

BACKGROUND: Postpartum depression (PPD) is a major public health concern because it adversely affects maternal health and children's physical and mental development. The prevalence of PPD in Arab countries is higher than the worldwide prevalence. Additionally, refugee women are more likely to develop PPD than women in the general population, but little research of refugee women in Arab countries is available. The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) have provided primary health care to Palestine refugees since 1950 and began the Mental Health and Psychosocial (MHPSS) programme in Jordan in 2017 to enhance the psychosocial and social wellbeing of Palestine refugees. We assessed the prevalence of PPD and examined associated factors among Palestine refugee women living in Amman, Jordan. METHODS: This cross-sectional descriptive study was done between April 21 and May 21, 2018. Eligible participants were Palestine refugee mothers who had given birth 3-16 weeks previously and were attending any of five UNRWA health centres in Amman that were launching the MHPSS programme. Data were gathered in face-to-face structured interviews that included the Edinburgh Postpartum Depression Scale (EPDS) to assess PPD, the Maternal Social Support Scale to assess levels of perceived social support, and a structured questionnaire about sociodemographic, obstetric or paediatric, psychological, and social factors. Participants with scores greater than 12 in the EPDS were classified as having depressive symptoms. Logistic regression was used to identify factors associated with depressive symptoms. The study protocol was approved by the Department of Health, UNRWA Headquarters, Amman, Jordan, and Nagasaki University. Each participant provided written informed consent. FINDINGS: 251 women participated in the study, with a mean age of 27·2 years (range 18-42, SD 5·43). 123 (49%) women were classified as having PPD. Logistic regression showed that factors associated with PPD were perceived low levels of social support (adjusted odds ratio 3·76, 95% CI 1·92-10·93) and experiencing stressful life events (one event 3·92, 1·51-9·91; two events 5·77, 2·33-14·27; and three or more events 14·8, 5·23-41·89). INTERPRETATION: The prevalence of PPD among Palestine refugee women in Amman was higher than that reported in a previous study of the general childbearing population (women aged 18-45 years) in Irbid in Jordan (22%, Mohammad et al. Midwifery 2011; 27: e238-45) but similar to findings in the West Bank (47%, Quandil et al. BMC Pregnancy Childbirth 2016; 16: 375) and in Syrian refugee women in Jordan (49·6%, Mohammad et al. Res Nurs Health 2011; 41: 519-245). Our findings highlight the need to address this disorder in Palestine refugee mothers. Periodical PPD screening, raising awareness about PPD, providing information to husbands and families, and building a support system for mothers could alleviate the risk of PPD. Future studies should examine whether factors of antenatal depression, which were not assessed in this study, correlate with having PPD to clarify the need for early intervention in mothers.

Assessment of physical activity and its facilitators and barriers among Syrian refugees living in Amman City, Jordan: a cross-sectional study.

BACKGROUND: Physical inactivity is one of the major risk factors for non-communicable diseases. Few studies about physical activity have been conducted among refugees from neighbouring countries. Given changes in the situation of Syrians, assessment of physical activity among Syrian refugees is required to understand their situation. This study aimed to evaluate the degree of self-reported physical activity and to identify perceived facilitators of and barriers to physical activity among Syrian refugees living in Amman, Jordan, in 2017. METHODS: This community-based cross-sectional study was conducted using a structured questionnaire and the short form of the International Physical Activity Questionnaire. Participants were eligible for the study if they were Syrian refugees aged 18-64 years, living in Amman city, and were either registered with the United Nations High Commissioner for Refugees, waiting for their registration, or had a service card issued by the Jordanian Ministry of Interior. The relationship between physical activity level and sex was assessed using the chi-square test and Cochran-Armitage tests. The Mann-Whitney U test was performed to assess the relationship between the median metabolic equivalent scores of physical activity and gender. Backward stepwise logistic regression analysis was used to analyse the association between predictors of physical inactivity and physical activity level. RESULTS: Among the 173 participants, the majority (91.9%) reported moderate to a high level of physical activity, and 8.1% were physically inactive. The metabolic equivalent scores for the walking activity of males (median: 1039.5, IQR: 0, 2772) was significantly higher than that of females (median: 396, IQR: 0, 1188) (p < 0.01). "Perceived change in the amount of physical activity" was a significant predictor of physical inactivity (adjusted OR = 3.00; 95%CI: 1.27-7.26). Common facilitators of physical activity were "psychological wellbeing"(49.7%) and "prevent diseases"(46.8%). The greatest barriers to physical activity were "time limitation"(43.4%) and "high cost"(57.8%). CONCLUSION: This study revealed the physical activity level among Syrian refugees in Amman. The perceived facilitators and barriers to physical activity identified among Syrian refugees were similar to those in previous studies conducted among non-refugees. These results provide a valuable baseline for future examinations of physical activity level and to verify its possible facilitators and barriers.

Has the double burden of malnutrition reached pupils in rural western Kenya?

BACKGROUND: Undernutrition and overnutrition have been considered separate challenges caused by the distinct factors in distinct settings. The double burden of malnutrition is defined as the coexistence of both undernutrition and overnutrition, which has now spread globally, especially in low- and middle-income countries. In Kenya, the double burden of malnutrition is present in the capital city but the situation in rural areas currently remains unknown. The aim of this study was therefore to analyze nutritional status in rural Kenya. METHODS: Data from height and weight measurements conducted by teachers in the third term of school year 2013 were collected from primary schools. Teachers were trained by experts before starting the measurements. The Z-scores of height-for-age, weight-for-age, and body mass index-for-age were calculated using AnthroPlus, and nutritional status was defined according to the World Health Organization guidelines. RESULTS: Data analyzed from 7,447 pupils (3,763 boys and 3,684 girls) showed that 12.4% were stunted and 7.8% were underweight among those ≤120 months old, and 11.7% were thin among those >120 months old. Boys were more likely to be stunted than girls. Boys were more likely to be underweight and girls were more likely to be overweight in the older age group. CONCLUSION: The double burden of malnutrition was not found, and undernutrition was still common among schoolchildren in the study area. However, it is important to monitor nutritional status due to adverse effects of rapid urbanization. Height and weight measurements in schools may be useful for monitoring the nutritional status of schoolchildren.

Depression and its associated factors among people with multidrug-resistant tuberculosis in Myanmar.

BACKGROUND: Depression is an important potential comorbidity in persons with tuberculosis (TB), yet data in many settings are scarce. OBJECTIVE: To estimate the prevalence and risk factors of depression in persons with multidrug-resistant tuberculosis (MDR-TB) in Myanmar. METHODS: A cross-sectional survey among MDR-TB participants at Aung San MDR-TB treatment centre in Yangon during routine clinic follow-up visits. Patients Health Questionnaire-9 (PHQ-9) in the local language was used to screen for depression and structured questionnaires conducted. Univariable and multivariable logistic regression models were performed to identify associations. RESULTS: Three-hundred and twenty-nine participants were enrolled between 19th December 2019 and 31st January 2020; 33% (111/329) in the intensive treatment phase. The prevalence of depressive symptoms (PHQ-9 ≥ 10) was (34/329) 10.33%. Multivariable analysis indicated financial hardship as a result of MDR-TB symptoms/treatment (aOR = 2.63, 95%CI: 1.12-6.67), suffering ≥1 respiratory symptoms (aOR = 6.72, 95%CI: 2.41-18.76), high education level (aOR = 4.26, 95%CI: 1.70-10.70), reported diabetes (aOR = 3.05, 95%CI: 1.16-7.99) as associated with depressive symptoms, with weak evidence of an association in females (aOR = 2.09, 95%CI: 0.94-4.65). CONCLUSION: Depressive symptoms are more common in those with comorbidities/TB symptoms. Further research is required to determine the effects of interventions to support persons with depressive symptoms identified using simple, standardised validated tools like PHQ-9.

Validation of serum apolipoprotein A1 in rabies virus-infected mice as a biomarker for the preclinical diagnosis of rabies.

Rabies is a type of acute fetal encephalitis caused by rabies virus (RABV). While it becomes incurable after symptom onset, it can be prevented by post-exposure prophylaxis (PEP) during the long incubation period. While preclinical diagnosis aids the appropriate PEP administration, it is mostly nonfeasible owing to the absence of viremia or a specific antibody response during the incubation period. Here, an attempt was made to identify a serum biomarker for the preclinical diagnosis of rabies. Using the serum from a mouse inoculated intramuscularly (i.m.) with 5 × 105 focus-forming units (FFU) of recombinant RABV expressing red firefly luciferase (1088/RFLuc) immediately before symptom onset, two-dimensional differential gel electrophoresis was conducted, followed by mass spectrometry, and it was confirmed that apolipoprotein A1 (ApoA1) was up-regulated. ELISA showed that the serum ApoA1 and specific antibody levels increased during the incubation period and on the day of symptom onset. Since a lower infectious dose can be used to induce the unstable and long incubation period generally observed in natural infection, the ApoA1 level in mice inoculated i.m. with 103 FFU of 1088/RFLuc was examined by monitoring viral dynamics using in vivo imaging. The serum ApoA1 and specific antibody levels were up-regulated in 50% and 58.3% of mice exhibiting robust RABV replication, respectively, but not in mice exhibiting weak RABV replication. In addition, it was reported that ApoA1 was found to be a biomarker for neuronal damage. Additional biomarker candidates will be needed for the effective preclinical diagnosis of rabies.

Current situation of children with disabilities in low- and middle-income countries.

Global child mortality has more than halved for the last three decades. Without a decrease in morbidity corresponding to that in mortality, this increased survival is likely to increase the number of children with disabilities, especially in low- and middle-income countries (LMICs). While population-based data on children with disabilities have been scarce in LMICs, it is estimated that among 52.9 million children with disabilities under 5 years worldwide, 95% live in LMICs. Sequelae of postnatal disease continue to be the major cause of child disability in LMICs; however, disability is increasingly the result of perinatal conditions. The Convention on the Rights of the Child and the Convention on the Rights of Persons with Disabilities promote the rights of children with disabilities, but limited resources in LMICs have prevented the translation of policies reflecting these Conventions into practice. Because health care for children with disabilities is limited in LMICs, most of them are cared for at home. This places heavy physical and mental burden on family caregivers and affects the allocation of time and financial resources in the family. Simple interventions can dramatically improve the clinical condition of disabled children and should be applied in care at home. Legally recognized members of society, children with disabilities remain excluded from public support. Disabled children must be empowered to overcome this inequity. This is the focus of the "Nothing About Us Without Us" campaign. Society, including professionals, can further redistribute power by "putting the first last" to empower individuals with disability.

Implementation of Kenyan comprehensive school health program: improvement and association with students' academic attainment.

There is growing evidence supporting the effectiveness of a comprehensive school health program. However, implementation in developing countries is a challenge. Furthermore, the available information on the association between a comprehensive school health program and students' academic attainment is limited. In Kenya, a project to verify the effects of a comprehensive school health program was carried out in Mbita sub-county, Homa Bay County from September 2012 to August 2017. This study aimed to clarify the improvement of school health during the project years and the association between school health and students' academic attainment. Primary schools in Mbita sub-county were selected as study sites. We assessed 44 schools' scores on a school health checklist developed from the Kenyan Comprehensive School Health Program, the students' mean score on the Kenya Certificate of Primary Education (KCPE), and absenteeism during the project years (2013-16). The mean school health checklist score (n = 44 schools) was 135.6 in 2013, 169.9 in 2014, 158.2 in 2015 and 181.3 in 2016. The difference of the mean score between 2013 and 2016 was significant. In addition, correlation analysis showed a significant association between mean KCPE score in the project years and school health checklist score (Pearson's coefficient was 0.43, p = 0.004). The results of this study suggest improvements of school health by the implementation of the Kenyan Comprehensive School Health Program and students' academic attainment.

Hepatitis B serologic survey and review of immunization records of children, adolescents and adults in Fiji, 2008-2009.

BACKGROUND: In Fiji, hepatitis B (HB) vaccine was introduced into childhood immunization program in 1989 and has been administered as a pentavalent since 2006. This study aimed to: (i) survey and examine the extent to which HB infection continue to occur in children, adolescents and adults in Fiji, and (ii) determine HB coverage rates and timeliness of vaccine administration to children. METHODS: Serum samples of children, adolescents and adults (aged 6 months to <5 years, 16-20 years, and 21-49 years, respectively) collected between 2008-2009 were tested for serologic markers of HB virus infection namely, HB surface antigen (HBsAg), anti-HBs and anti-HB core antigen (anti-HBc). Health record card of each child was reviewed. RESULTS: None of the participating children (0/432) was positive for HBsAg. Overall prevalence of HBsAg among adolescents and adults was 5.6% (7/124) and 3.2% (12/370), respectively. High prevalence (98.1%) of anti-HBs was observed in children. An estimated 17.4% of adolescents and adults had evidence of past HBV infection (anti-HBc positive), of which 87.2% recovered from infection but the remaining 12.8% developed chronic infection. Percentage of children who completed at least 3 doses of HB immunization was 99.3%, and who received them on schedule was 58.5%. CONCLUSION: Although sample populations for this study is less robust compared to 1998, the prevalence of HBsAg and anti-HBc in children and adults before and after the implementation of the immunization program is much lower. The findings are a positive step in showing that Fiji's HB vaccine control program is achieving its objectives.

Caregivers' understanding of pediatric medication in central Malawi.

OBJECTIVE: To investigate caregivers' understanding of prescriptions of antibiotics and antimalarials for children in Malawi. METHOD: A cross-sectional study using interviews with 513 caregivers was undertaken in three different medical settings in two districts in Malawi for their understanding of medication defined as comprehension of dosage, frequency and duration immediately after receiving medicine, and its association with their sociodemographic characteristics. RESULTS: Nearly half (49%) of the caregivers understood medication on the day of prescription. Understanding varied by type of drug. Sixty-five percent understood medication for antimalarials, LA (lumefantrine and artemether), while only 38% understood medication for amoxicillin syrup. Multivariate analysis showed that caregivers with higher education and older children had greater understanding. CONCLUSIONS: Caregivers' understanding of pediatric medication was differentially related to kinds and types of medicine as well as their education level. The instruction to caregivers on how to administer medication should be evaluated especially when they are less educated.

Factors associated with health-related quality of life among pulmonary tuberculosis patients in Manila, the Philippines.

PURPOSE: Health-related quality of life (HRQOL) among pulmonary tuberculosis (PTB) patients has not been investigated in the Philippines. This study aimed to describe HRQOL among PTB patients and to determine factors that are associated with HRQOL. METHODS: A cross-sectional survey was conducted at 10 public health centers and 2 non-government organization clinics in District I, Tondo, Manila. Face-to-face interviews using a structured questionnaire including Short Form-8, Duke-UNC Functional Social Support Questionnaire, and Medical Research Council (MRC) dyspnea scale were performed with 561 PTB patients from September to November 2012. RESULTS: HRQOL among PTB patients was generally impaired. Factors associated with lower physical component summary were exposure to secondhand smoke (SHS) (P = 0.038), positive sputum smear result (P = 0.027), not working (P = 0.038), lower education level (P < 0.01), number of symptoms (P < 0.01), number of adverse drug reactions (ADRs) (P < 0.01), higher score on the MRC dyspnea scale (P < 0.01), and low perceived social support (P = 0.027). Lower body mass index (P = 0.016), non-SHS exposure (P = 0.033), number of symptoms (P < 0.01), number of ADRs (P < 0.01), low perceived social support (P < 0.01), and negative perception for waiting time in the clinic (P = 0.026) were identified to be factors significantly associated with lower mental component summary. CONCLUSION: Socioeconomic status including SHS exposure and low perceived social support, in addition to clinical factors, may be associated with poor HRQOL. Further study would be needed to assess our findings.

Village health volunteers' social capital related to their performance in Lao People's Democratic Republic: a cross-sectional study.

BACKGROUND: Improving the performance of community health workers (CHWs) is a global issue. The relationship between CHWs and their community may impact their performance. In Lao People's Democratic Republic (Lao PDR), CHW are called village health volunteers (VHV). Lao PDR has a problem with VHV inactivity, especially in rural areas. This study focused on which aspects of social capital are related to VHV performance. METHODS: This research represents a cross-sectional study with a quantitative survey based primarily on interviews using a semi-structured questionnaire. Interviews were conducted with 149 VHVs living and working in the Sepon District. VHV performance evaluation was measured with scores on a 5-point scale, and the cutoff point for designating performance as good or poor was set at the median score. This evaluation of VHV performance was conducted as a self-evaluation by VHVs and by health center staff who were supervisors of the VHVs. Measurement of social capital was accomplished using the short version of the Adapted Social Capital Assessment Tool (SASCAT). For statistical analyses, logistic regression was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI). RESULTS: The results of multiple logistic regression adjusted by moderator variables showed that citizenship activities in the structural social capital component of SASCAT were significantly related to performance in self-evaluation by VHVs (adjusted OR: 2.10, 95% CI: 1.19-3.71) and the evaluations by health center staff (adjusted OR: 1.67, 95% CI: 1.01-2.77). Support from groups (adjusted OR: 1.87, 95% CI: 1.27-2.76) and cognitive social capital (adjusted OR: 7.48, 95% CI: 2.14-26.10) were found to be significantly associated but only for VHV self-evaluation. CONCLUSIONS: The results suggest that individuals who interact with important figures in the community and who cooperate with other villagers whenever problems arise, i.e., have social capital, exhibit good performance as VHVs. These findings suggest that increasing citizenship activities could increase the retention rate of CHWs and help improve their performance. Citizenship activities could also be used as a predictive indicator when selecting new CHWs.

Protocol for a Randomized Control Trial for Tungiasis Treatment in Homa Bay County, Kenya: Dimeticone versus Sodium Carbonate.

Tungiasis, a World Health Organization neglected tropical disease, is caused by the female sand flea. Most clinical trials for tungiasis use expensive or impractical drugs, which are difficult for residents to use. However, in western Kenya, communities successfully treat tungiasis with sodium carbonate. We hypothesise that the topical risk-difference of 5% sodium carbonate is no more than 10% non-inferior to dimeticone (NYDA®) for tungiasis treatment. This is a protocol for a non-inferiority study, which will be randomised and with an observer-blinded control. The study will have two arms: 5% sodium carbonate and NYDA®, one on each foot, and will take place at state primary schools in Homa Bay County, Kenya. Fleas identified among school children aged 8-14 years with sand-flea lesions will be enrolled in the study. For each participant, the viability of the embedded fleas, clinical signs including inflammation, and symptoms will be monitored for seven days after treatment. The proportion of dead fleas will be compared in the primary analysis. All adverse events will be monitored throughout the study period. We expect to identify the most effective treatment between sodium carbonate and NYDA® for tungiasis, which can be adopted in the community.

Lifestyle Risk Behaviours and Nutritional Status Associated with Mental Health Problems among Myanmar Adolescents: Secondary Analysis of a Nationwide 2016 School Survey.

Engaging in unhealthy lifestyles may be considered a risk factor for mental health problems, but there is limited evidence. This study aimed to identify the relationship between unhealthy lifestyles and mental health problems among Myanmar school-going adolescents. Global School Based Student Health Survey (GSHS) data from 2838 school-going adolescents from Myanmar were analysed. Bivariable and multivariable logistic regression analyses were applied. After adjusting for confounding variables, adolescents who were seated for more than three hours per day had higher odds of loneliness, anxiety-induced sleep disturbance, suicide ideation, and suicide attempts compared to others. Moreover, students who ate fruit less than one time per day were more likely to experience anxiety-induced sleep disturbance and suicidal ideation. Being a current drinker was significantly associated with suicidal ideation and attempt. Obese students were more likely to feel lonely compared to normal weight students. Our study indicates there is a strong association between unhealthy lifestyle behaviours and mental health problems among school adolescents in Myanmar.

The clinical characteristics, etiologic pathogens and the risk factors associated with dehydration status among under-five children hospitalized with acute diarrhea in Savannakhet Province, Lao PDR.

BACKGROUND: Acute diarrhea is a common health problem in children, especially those under five years of age (U5). The mortality rate due to acute diarrhea among U5 children accounted for 11% in Lao PDR in 2016. No study has been done to investigate the etiologic pathogens of acute diarrhea and the risk factors associated with dehydration status among U5 children hospitalized with acute diarrhea in this region. OBJECTIVES: The study aimed to evaluate the clinical characteristics, etiological agents and associated factors of dehydration status of acute diarrhea among hospitalized U5 children in Savannakhet Province, Lao PDR. METHODS: This retrospective study reviewed paper-based medical records with available stool examination results of 33 U5 children hospitalized with acute diarrhea in Savannakhet Provincial Hospital, Lao PDR between Jan. 2018 and Dec. 2019. Descriptive statistics were used to describe clinical characteristics and etiologic agents of acute diarrhea of the children. Nonparametric test, Pearson's Chi-square test and Fisher exact test were used to determine the risk factors associated with level of dehydration of the participants. RESULTS: Vomiting was the most common symptom (66.6%), followed by fever (60.6%). Dehydration was found in 48.4% of subjects. Rotavirus was the most common identified pathogen with a prevalence of 55.5%. Bacterial enteric infection was identified in 15.1% of patients. There is a significantly higher prevalence of dehydration among children with acute diarrhea caused by rotavirus compared to those with negative rotavirus testing (70.0% vs. 12.5%, p = 0.02). CONCLUSIONS: Rotavirus was the most prevalent pathogen of acute diarrhea among U5 children. Pediatric patients with acute diarrhea caused by rotavirus had a higher prevalence of dehydration compared to those with negative rotavirus testing.

Household survey on owned dog population and rabies knowledge in selected municipalities in Bulacan, Philippines: A cross-sectional study.

BACKGROUND: Despite the effort to eradicate rabies in the Philippines, human rabies cases have not decreased in the past decade. Rabid dogs pose the most significant hazard in the countries with the highest burden of rabies, and 70% rabies vaccine coverage is recommended for dogs in high-risk areas. Ascertaining the owned dog population and community knowledge on rabies can help improve vaccine coverage and information campaigns. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cross-sectional survey in six randomly selected communities (five urban, one rural) in Central Luzon, Philippines. We first conducted the complete mapping of 9,173 households and then randomly selected 727 households. More than half (54.1%) of the households owned dogs (1.21 dogs/household). In the 727 households, we identified 878 owned dogs and 3256 humans. According to these results, the dog-to-human ratio was approximately 1:3.7. Only 8.8% of households reported a history of dog bite in 2019. Among dog-owning households, 31% reported that they allow their dogs to roam freely. Of the recorded dogs, 35.9% have never been vaccinated, and only 3.5% were spayed or castrated. Factors associated with lower rabies knowledge include (1) no education aOR: 0.30 (0.16-0.59), and (2) only primary school education aOR: 0.33 (0.22-0.49). In contrast, factors associated with higher knowledge include (1) owning a dog and not allowing them to roam freely aOR: 2.01 (1.41-2.87) and (2) owning a dog and allowing them to roam freely aOR: 1.84 (1.17-2.92), when compared to those with no dogs. CONCLUSIONS/SIGNIFICANCE: We identified a larger dog population in the community than the usual estimates (1:10), suggesting that annual vaccine needs in the Philippines must be reassessed. Our survey shows a relatively good understanding of rabies; however, awareness of the concept of rabies as a disease, and how animals and humans can acquire it, is lacking.

Lateral flow devices for samples collected by straw sampling method for postmortem canine rabies diagnosis.

The direct fluorescent antibody test (dFAT) using brain sample after opening the skull is the standard rabies diagnostic test in animal rabies. However, it is not feasible in many resource-limited settings. Lateral flow devices (LFD) combined with a simple sampling methodology is quicker, simpler, and less hazardous than the standard test and can be a useful tool. We conducted a prospective on-site study to evaluate the diagnostic accuracy of the LFD with the straw sampling method compared with that of the dFAT with the skull opening procedure for post-mortem canine rabies diagnosis. We collected 97 rabies-suspected animals between December 1, 2020 and March 31, 2021. Among the 97 samples, 53 and 50 cases were positive tests for dFAT and LFD, respectively. The sensitivity and specificity of LFD with straw sampling method were 94.3% (95% confidence interval [CI], 84.3-98.8%) and 100% (95% CI, 92.0-100%), respectively. The performance of LFD by the straw sampling method showed relatively high sensitivity and 100% specificity compared with that of dFAT performed on samples collected after opening the skull. This methodology can be beneficial and is a strong tool to overcome limited animal surveillance in remote areas. However, because of our limited sample size, more data using fresh samples on-site and the optimizations are urgently needed for the further implementation in endemic areas.

Background and descriptive features of rabies-suspected animals in Central Luzon, Philippines.

BACKGROUND: The Philippines is one of the major endemic countries for canine rabies in Southeast Asia. However, detailed description and analysis of laboratory-confirmed animal rabies are limited. Highly accurate surveillance requires a thorough understanding of the target area-specific problems and obstacles. Therefore, we aim to describe and analyze the rabies suspect animals in Central Luzon, Philippines, to clarify the characteristics of management and clinical signs by conducting interviews with the owners. METHODS: We prospectively collected information on the rabies suspect animals submitted to the Regional animal laboratory in Central Luzon through passive laboratory-based rabies surveillance between 1st April 2019 and 30th September 2020. We performed active interviews directly or telephonically with the owner. The direct fluorescent antibody test was performed on the hippocampus, brain stem, and cerebellum for laboratory confirmation. Descriptive statistics were used to characterize the number of rabies cases according to management methods and characteristics of suspected animals during the observation period. Clinical symptoms of suspected rabid animals were analyzed by univariate logistic regression analysis. RESULTS: There were 292 sample submissions during the study period. Of these, 160 were positive for dFAT. Samples of pet animals (85.3%) provided by owners or their acquaintances (59.2%) accounted for the majority of laboratory confirmed cases. Case mapping showed that more rabies-suspected cases were sent from areas near the regional laboratory than from those far from the laboratory, despite the incidence of rabies being high in these areas. The management and clinical symptoms of 227 animal cases showed that most owners were managing their animals at home and were allowing them to roam outside (69.6%) and be unvaccinated (78.9%). Rabid animals were more likely to manifest aimless running, restlessness, and agitation. CONCLUSIONS: Our study provided some features of animals with laboratory-confirmed rabies in Central Luzon. However, most of the samples were submitted from areas near the rabies diagnosis laboratory, and the number of samples submitted from remote areas was low. To improve the surveillance capacity, it is necessary to increase sample submissions from remote areas.

HIV infection, and overweight and hypertension: a cross-sectional study of HIV-infected adults in Western Kenya.

BACKGROUND: Non-communicable diseases (NCDs) are increasing in Kenya, where HIV/AIDS remains a leading cause of death; however, few studies have investigated obesity and hypertension among adults with HIV infection. We conducted a cross-sectional study in Homa Bay, Western Kenya, during 2015 to determine the prevalence of overweight/obesity and hypertension among HIV-infected adults and to identify their risk factors. RESULTS: Anthropometric measurements and a structured questionnaire were administered to adults with HIV infection receiving care at Mbita Sub-county Hospital. A total of 251 HIV-positive individuals were enrolled. More women were overweight (17.2%) and obese (3.6%) than underweight (8.3%). The prevalence of abdominal obesity was high in women (62.7%), especially those aged 30-39 years. The prevalence of hypertension was 9.8% and 11.8% in men and women, respectively. Male participants tended to develop hypertension at an early age. Multivariate analysis showed that female sex was significantly associated with abdominal obesity. Regarding clinical factors, we identified an association between overweight and a history of opportunistic infections, as well as between hypertension and World Health Organization clinical stage. Sixty percent of HIV-infected participants assumed that a very thin body size indicated HIV infection. CONCLUSIONS: The main findings of this study include a greater prevalence of overweight than underweight as well as a high prevalence of abdominal obesity among women. Social perception toward body size among people with HIV infection might remain problematic. Individuals living with HIV in Kenya should receive preventive intervention for overweight and abdominal obesity, with consideration of relevant social and cultural aspects.

Evaluation of the diagnostic accuracy of lateral flow devices as a tool to diagnose rabies in post-mortem animals.

Implementation of lateral flow devices (LFDs) for rabies antigen detection is expected to improve surveillance through the efficient detection of rabid animals in resource-limited settings; however, the use of LFDs for diagnosis remains controversial because some commercially available kits show low sensitivity. Therefore, we compared the diagnostic efficacy of three LFDs (ADTEC, Bionote, and Elabscience kits) paralleled with the direct fluorescent antibody test (dFAT) using fresh samples and investigated the diagnostic accuracies. To do so, we evaluated rabies-suspected samples submitted to the Regional Animal Disease Diagnostic Laboratory III, Philippines. Furthermore, we conducted real-time RT-PCR and sequencing to measure the accuracy of field laboratory diagnosis. The total number of animals submitted during this study period was 184 cases, including negative control samples. Of these, 53.9% (84 cases) were positive in the dFAT. Dogs were the most common rabies-suspected animal (n = 135). The sensitivities of the ADTEC and Bionote kits were 0.88 (74 cases) and 0.95 (80 cases), respectively. The specificity of both kits was 1.00 (100 cases). Furthermore, the sensitivity and specificity of the ADTEC kit after directly homogenizing the samples in assay buffer without dilution in phosphate-buffered saline (ADTEC kit DM) were 0.94 (79 cases) and 1.00 (100 cases), respectively. By contrast, there were no positive results using the Elabscience kit among all dFAT-positive samples. The sensitivity and specificity of LFDs make these tests highly feasible if properly used. Therefore, LFD tests can be used to strengthen the surveillance of rabies-infected animals in endemic and resource-limited settings.
