    Background: In the past decade, Yemen has witnessed several disasters that resulted in a crumbled healthcare system. With the declaration of COVID-19 a global pandemic, and later the appearance of first confirmed cases in Yemen, there is an urgent need to assess the preparedness of healthcare facilities (HCFs) and their capacities to tackle a looming COVID-19 outbreak. Herein, we present an assessment of the current state of preparedness and capabilities of HCFs in Yemen to prevent and manage the COVID-19 outbreak. Methods: An online survey for HCFs was developed, validated, and distributed. The questionnaire is divided into five main sections: (1) Demographic variables for participants. (2) HCFs capabilities for COVID-19 outbreak. (3) Support received to face the emergence and spread of COVID-19. (4). Current practices of infection prevention and control measures in the HCFs. The last section focused on the recommendations to ensure effective and timely response to this outbreak in Yemen. Descriptive analysis was used to analyze data using statistical package for social sciences (SPSS), version 23. Results: Responses were received from healthcare workers (HCWs) from 18 out of 22 governorates in Yemen. Out of the 296 HCWs who participated in the study, the vast majority (93.9%) believed that the healthcare system in Yemen does not have the resources and capabilities to face and manage a COVID-19 outbreak. Approximately 82.4% of participants rated the general preparedness level of their HCFs as very poor or poor. More specifically, the majority of HCWs rated their HCFs as very poor or poor in term of availability of the following: an adequate number of mechanical ventilators (88.8%), diagnostic devices (88.2%), ICU rooms and beds (81.4%), and isolation rooms (79.7%). Conclusions: The healthcare facilities in Yemen are unprepared and lack the most basic resources and capabilities to cope with or tackle a COVID-19 outbreak. With the current state of a fragile healthcare system, a widespread outbreak of COVID-19 in Yemen could result in devastating consequences. There is an urgent need to provide support to the healthcare workers and HCFs that are on the frontline against COVID-19.

    Background Studies have revealed that the inclusion of a clinical pharmacist as a member in multidisciplinary medical team has been associated with improved medication use, reduced adverse drug reaction, reduced cost of treatment, and improved health outcomes. Objective The objectives of this study were to evaluate the implementation of clinical pharmacy recommendations and services, the acceptance rate by the physicians, and the anticipated outcomes of the recommendations at a hospital in Yemen. Methods Different units of the University of Science and Technology Hospital, Sana'a were included in this study. All the recommendations and services provided by the clinical pharmacist during daily activities were documented between June 2013 and November 2015. The provided recommendations were classified based on the type, acceptance rate, and the anticipated outcomes. Main outcome measure Type and quality of clinical pharmacists' recommendations, anticipated impact of the recommendations on health outcomes, and their acceptance rate. Results Throughout the study period, a total of 957 patients in different hospital units were visited and provided with a total of 3307 interventions and services. The most frequent types of clinical pharmacist's interventions were drug discontinuation (23.6%, n = 782), inappropriate dose interval or time (n = 735, 22.2%), and add medication (18.9%, n = 626). Overall, 61.8% (n = 2044) of the provided recommendations were accepted by the physicians. The most anticipated outcomes were improved the effectiveness of therapy (45.1%, n = 1909), avoid adverse drug reactions (29%, n = 1228), and decrease the cost of medications (18.8%, n = 797). Conclusion Clinical pharmacist's recommendations resulted in improving drug therapy and decreasing adverse effects for inpatients at the University of Science and Technology Hospital. This suggests that the implementation of clinical pharmacy services is essential and has a positive outcome on patient care.

    Between June 2008 and March 2009, a cross-sectional study of human malaria was carried out in four governorates of Yemen, two (Taiz and Hodiedah) representing the country's highlands and the others (Dhamar and Raymah) the country's coastal plains/foothills. The main aims were to determine the prevalences of Plasmodium infection among 455 febrile patients presenting for care at participating health facilities and to investigate the potential risk factors for such infection. Malarial infection was detected in 78 (17·1%) of the investigated patients and was more likely to be detected among the febrile patients from the highlands than among those presenting in the coastal plains/foothills (22·6% v.13·9%; χ(2)=10·102; P=0·018). Binary logistic-regression models identified low household income [odds ratio (OR)=13·52; 95% confidence interval (CI)=2·62-69·67; P=0·002], living in a household with access to a water pump (OR=4·18; CI=1·60-10·96; P=0·004) and living in a household near a stream (OR=4·43; CI=1·35-14·56; P=0·014) as significant risk factors for malarial infection in the highlands. Low household income was the only significant risk factor identified for such infection in the coastal plains and foothills (OR = 8·20; CI=1·80-37·45; P=0·007). It is unclear why febrile patients in the highlands of Yemen are much more likely to be found to have malarial infection than their counterparts from the coastal plains and foothills. Although it is possible that malarial transmission is relatively intense in the highlands, it seems more likely that, compared with those who live at lower altitudes, those who live in the highlands are less immune to malaria, and therefore more likely to develop febrile illness following malarial infection. Whatever the cause of the symptomatic malarial infection commonly found in the highlands of Yemen, it is a matter of serious concern that should be addressed in the national strategy to control malaria.

    Malaria in Yemen is mainly caused by Plasmodium falciparum and 25% of the population is at high risk. Sulfadoxine-pyrimethamine (SP) had been used as monotherapy against P. falciparum. Emergence of chloroquine resistance led to the shift in anti-malarial treatment policy in Yemen to artemisinin-based combination therapy, that is artesunate (AS) plus SP as first-line therapy for uncomplicated malaria and artemether-lumefantrine as second-line treatment. This study aimed to screen mutations in the dihydrofolate reductase (dhfr) and dihydropteroate synthetase (dhps) genes associated with SP resistance among P. falciparum population in Hadhramout governorate, Yemen.

    The heavy metal (HM) pollution in sediment is of serious concern, particularly in the Red Sea environment. This study aimed to review and compile data on the concentrations of four HMs (Cd, Cu, Pb, and Zn) in the coastal surface sediments from the Red Sea, mainly from Saudi Arabia, Egypt, and Yemen, published in the literature from 1992 to 2021. The coastal sediments included those from mangrove, estuaries, and intertidal ecosystems. It was found that the mean values of Cd, Cu, Pb, and Zn in coastal Red Sea sediments were elevated and localized in high human activity sites in comparison to the earth upper continental crust and to reference values for marine sediments. From the potential ecological risk index (PERI) aspect, 32 reports (47.1%) were categorized as 'considerable ecological risk' and 23 reports (33.8%) as 'very high ecological risk'. From the human health risk assessment (HHRA) aspect, the non-carcinogenic risk (NCR) values (HI values < 1.0) of Cd, Cu, Pb, and Zn represented no NCR for the ingestion and the dermal contact routes for sediments from the Red Sea countries. The reassessment of the HM data cited in the literature allowed integrative and accurate comparisons of the PERI and HHRA data, which would be useful in the management and sustainable development of the Red Sea area, besides being a helpful database for future use. This warrants extensive and continuous monitoring studies to understand the current and the projected HM pollution situation and to propose possible protective and conservative measures in the future for the resource-rich Red Sea ecosystem.

    BACKGROUND: Previous cross-sectional studies have reported limited knowledge and practices among nurses regarding controlling nosocomial infections (NIs). Even though health institutions offer many irregular in-service training courses to solve such issues, a three year-nursing educational programme at institutions is not adequate to enable nurses to handle NIs. Therefore, this study aims to evaluate the implementation of an educational module on NIs control measures among Yemeni nurses.

    METHODS: A single-blinded randomised hospital-based trial was undertaken involving 540 nurses assigned to two intervention groups and a waitlist group. Intervention group-1 received a face-to-face training course comprising 20 h spread over six weeks and a hard copy of the module, while intervention group-2 only received the hard copy of the module "without training". In contrast, the waitlist group did not receive anything during the period of collecting data. A self-administered NI control measures-evaluation questionnaire was utilised in collecting the data from the participants; before the intervention, at six weeks and 3 months after the end of the intervention. The period of data collection was between 1st May and 30th October 2016.

    RESULTS: The results from collecting and analysing the data showed a statistically significant difference in the mean knowledge scores between the intervention groups that were detectable immediately post-intervention with a mean difference (MD) of 4.31 (P Yemen.

    TRIAL REGISTRATION: Nosocomial infection educational module for nurses ISRCTN19992640 , 20/6/2017. The study protocol was retrospectively registered.

    Introduction: The Gallbladder stone (GBS) disease is most commonly asymptomatic that may lead to several complications such as ascending cholangitis and obstructive jaundice. In this study the frequency of gallblad- der stones among patients referred for abdominal ultrasound at the University of Science and Technology hospital (USTH), Sana’a – Yemen, have been estimated during the period between January and June 2013. Methods: This study is a record-based and conducted at the radiology department in USTH, on cases underwent abdominal ultrasound during the period from January – June 2013. Information were collected from abdominal ultrasonography reports. Results: In this study 4935 patients’ records are included. Of them, 2541 were males and 2394 were females. The frequency of patients with GBS was 5.53%. Multiple stones were observed in 3.57% of patients and 4.34% patients had large stones with size  5 mm. Females had significantly higher frequency of GBS (8.0%: 191/2394) than males (3.2%: 82/2541) (P < 0.001). It was found that, no significant difference between males and females in harboring small stones (< 5mm) (P = 0.251). However, significantly higher frequency of large GBS ( 5 mm) was found among females compared to males (P < 0.001). The frequencies of GBS, small size of GBS and large size of GBS have significantly increased with increasing age (P < 0.001). Conclusion: In this study it was found that females had significantly higher frequency of GBS than males. No significant difference between males and females in harboring small stones. There was a significantly higher frequency of large GBS was found among females compared to males. The frequencies of GBS, small size of GBS and large size of GBS have significantly increased with increasing age.

    BACKGROUND: Risk evaluation of atherosclerotic cardiovascular disease (ASCVD) remains the cornerstone of primary prevention. The cardiovascular risk assessment can guide the decision-making on various preventive measures such as initiating or deferring statin therapy. Thus, our study aimed to assess the physicians' knowledge, attitude, and practices regarding atherosclerotic cardiovascular diseases risk assessment. Also, we evaluated the physician-patient discussion and counseling practices before statin therapy initiation in concordance with recommendations from the latest clinical practice guideline.

    METHODS: A cross-sectional study was conducted between November 2020 and January 2021. A self-administered questionnaire was distributed to 350 physicians (GPs, residents, specialists, and consultants). Two trained pharmacists distributed the questionnaires in 5 major tertiary governmental hospitals and more than ten private hospitals. Also, private clinics were targeted so that we get a representative sample of physicians at different workplaces.

    RESULTS: A total of 270 physicians filled the questionnaire out of 350 physicians approached, with 14 being excluded due to high missing data, giving a final response rate of 73%. Participants had suboptimal knowledge and practices with a high positive attitude toward atherosclerotic cardiovascular diseases risk assessment. The knowledge and practices were higher among consultants, participants from the cardiology department, those with experience years of more than nine years, and those who reported following a specific guideline for cholesterol management or using a risk calculator in their practice. Notably, the risk assessment and counseling practices were lower among physicians who reported seeing more patients per day.

    CONCLUSION: Physicians had overall low knowledge, suboptimal practices, and a high positive attitude toward cardiovascular risk assessment. Therefore, physicians' training and continuing medical education regarding cholesterol management and primary prevention clinical practice guidelines are recommended. Also, the importance of adherence to clinical practice guidelines and their impact on clinical outcomes should be emphasized.

    Introduction An Analysis of a Survey Questionnaire on health care workers’ knowledge and practices regarding of infection control and complains them to apply universal precautions. Health care workers are at substantial risk of acquiring blood borne pathogen infections through exposure to blood or other products of patients. To assess of infection control among health care workers in Sana'a healthcare centers, Yemen.
    Methods A cross-sectional study was conducted in the health center to assess knowledge and practices regarding of infection control among 237 health workers in Sana,a city. A structured self-administered questionnaires were used and data was analyzed using SPSS version 20 and the associations were tested with chi-square, with p-value of < 0.05.
    Results The health care workers in public centers ware (51.1%) and (48.9%) of them works in private centers. One hundred and seventeen (49.4%) respondents had poor infection control knowledge, 113 (43.5%) had fair knowledge, and 17 (7.2%) had good knowledge. The knowledge was significantly associated with type of center (P < 0.018), such that the public center had the highest proportion with poor knowledge. And nurses and midwife having the highest proportion with fair knowledge of infection control. Eight (3.4%) respondents had a poor practice of universal precautions, 93 (39.2%) had fair practice, and 136 (57.4%) good practice. The practice was significantly associated with the profession, level of education and work experience (P < 0.001), (P < 0.006), (P < 0.001) respectively, and nurses and midwives as the profession with the highest proportion with good practice.
    Conclusion We conclude that the practices and knowledge of universal precautions were low and that's need for intensive programmes to educate health care workers on various aspects of standard precautions and infection control programmes and policies.

    Few studies have explored diagnosis delay by tuberculosis (TB) patients and its effects on the rate of infection among their close contacts. A cross-sectional study of the close contacts of 505 newly diagnosed TB patients was conducted in a TB referral centre in Sana'a, Yemen from 2008 to 2010. Only the close contacts of 89 new TB patients agreed to participate and completed the tuberculin skin test (TST). Of the 239 close contacts investigated, 133 (55.6%) had a positive TST result. Index patients were classified as long or short diagnosis delay (above or below the median). There was no significant difference in the number of infected close contacts between long and short delay index patients (Mann-Whitney U-test). A larger sample size, with more incentives for patients to participate and the use of other investigative tools could provide a better picture of the pattern of TB transmission among all contacts.

    OBJECTIVES: This study aimed to determine the level and factors contributing to burnout among doctors in Sana'a City, Yemen and to determine the relationship between burnout and psychological morbidity.

    METHODS: This was a cross-sectional study of 563 working doctors in the four main hospitals in Sana'a City, Yemen. The 12-item version of the General Health Questionnaire (GHQ12) was used as a measure of psychological morbidity and the 22-item Maslach Burnout Inventory (MBI) was used to measure emotional exhaustion, depersonalization, and personal accomplishment. Sources of job stress were determined using a 37-item scale questionnaire. The questionnaire elicited information about socio-demographic and work characteristics.

    RESULTS: On the MBI, 356 doctors showed high emotional exhaustion (63.2%), 109 showed high depersonalization (19.4%) and 186 showed low personal accomplishment (33.0%). Sixty six doctors (11.7%) were identified as experiencing a high degree of burnout (high emotional exhaustion and depersonalization and low personal accomplishment). The prevalence of high degree of burnout was significantly higher in those with duration of work or=40 h/wk (OR=2.1, 95% CI 1.25-3.62) and in those who had psychological morbidity (OR=5.3, 95% CI 2.22-12.39). Thirteen out of 37 sources of stress were significantly associated with high degree of burnout. In multivariate analysis, the significant predictors of high burnout were: dealing with patient's psychosocial problems, feeling of isolation, disturbance of home/family life by work, not chewing khat, long working hours and psychological morbidity.

    CONCLUSION: The prevalence of high degree of burnout as well as emotional exhaustion in Yemeni doctors was higher than those reported internationally and was associated with psychological morbidity and many important sources of job stress.

    The first case of COVID-19 in Yemen was confirmed on 10 April 2020. Having faced with a six-year long conflict that has destroyed half of its healthcare facilities and displaced millions, predictions of infections and mortality in Yemen suggested a looming healthcare catastrophe. Difficulty in implementing coordinated lockdowns and preventive measures due to the daily labor working nature of the majority of the population, provided the perfect breeding ground for the SARS-CoV-2 virus. However, official figures of infections and mortality are very low and there have not been confirmed reports of excess mortality. This could indicate that Yemen is silently marching towards forced herd immunity. Seroprevalence studies will provide useful insight into the COVID-19 transmission trajectory in Yemen, which can serve as a guide in planning vaccine distribution strategies and allocating the limited funds wisely.

    BACKGROUND: This cross-sectional survey aimed to assess the knowledge, attitudes and practices (KAP) towards schistosomiasis among rural schoolchildren in Taiz governorate, southwestern Yemen.

    METHODS: A total of 406 children were screened for urogenital and intestinal schistosomiasis. A pretested questionnaire was used to collect the children's demographic and socio-economic information and their KAP towards schistosomiasis.

    RESULTS: Overall, 73 children (18%) were found to be infected by Schistosoma mansoni. None of the children were positive for Schistosoma haematobium. The prevalence of intestinal schistosomiasis was significantly higher among boys than girls (22.1% vs 12%; p=0.010). Approximately two-thirds (63.3% [257/406]) of the children had heard about schistosomiasis, however, only 38.5%, 53.6%, 28.4% and 38.1% had correct knowledge concerning the causes, symptoms, transmission and prevention, respectively. A significantly higher level of knowledge was observed among boys and Schistosoma-infected children compared with girls and non-infected children (p<0.05). However, a better level of knowledge does not seem to translate directly into the performance of hygienic practices. Multivariate logistic regression showed that sex and infection status were the significant predictors of good knowledge.

    CONCLUSIONS: Intestinal schistosomiasis is prevalent among schoolchildren in rural Yemen. The findings reveal that children's knowledge about schistosomiasis is inadequate. Therefore, besides mass drug administration, integrated control programmes should also include health education and the provision of improved drinking water and proper sanitation.

    Background: Low birth weight can lead to infant death, especially during the first year of life.

    Aims: To assess risk factors related to low birth weight babies in Sana'a, Yemen.

    Methods: We conducted an unmatched case-control study of 252 women who came for delivery at Al Thawra Hospital, Sana'a, Yemen, between August and October 2016.

    Results: Significant risk factors for low birth weight were: birth interval < 2 years; history of pre-eclampsia during current pregnancy; preterm gestational age < 37 weeks; and khat chewing or smoking during pregnancy. After controlling for all the confounders, only birth interval < 2 years was significantly associated with low birth weight.

    Conclusion: Shorter birth interval is an important risk factor for low birth weight; therefore, improving maternal awareness of this should be emphasized during postnatal follow-up.

    BACKGROUND: Cutaneous leishmaniasis (CL) is a major health problem in Yemen and is endemic in many rural areas across the country.

    METHODS: A community-based cross-sectional survey followed by unmatched case-control comparisons was conducted among 612 participants in Utmah district, western Yemen. A total of 223 participants were included in the case-control analysis to identify the significant risk factors. Skin scrapping samples were examined by microscopy and internal transcribed spacer 1 nested polymerase chain reaction.

    RESULTS: Overall, 33% (202/612) of the participants had active skin lesions and/or scars that met the clinical criteria for CL. A total of 90 (14.7%) participants had suspected active CL lesions; however, a prevalence of 8.7% (53/612) was obtained based on molecular and parasitological examination, with Leishmania tropica being the only causative agent identified. Multivariable logistic regression analyses showed that being ≤10 y old, being female, living in houses with cracked walls, living in the presence of other family members with typical ulcerating skin diseases and sleeping outside were factors significantly associated with an increased likelihood of having CL. Moreover, keeping livestock on the ground floor of the house was significantly associated with a decreased likelihood of having CL.

    CONCLUSION: The study reveals an alarmingly high prevalence of CL among the studied population. Therefore there is an urgent need for effective control measures and improved treatment efforts against this devastating disease.

    Pollens and seeds of Hypoestes and Rhinacanthus collected from different field localities in Taiz and Soqotra Island, Yemen were investigated by using light and scanning electron microscopes. Pollen grains of Hypoestes were prolate in equatorial view, lobate trigonal to lobate circular in polar view whereas those of Rhinacanthus were subspheroidal and rounded trigonal in polar view. The aperture was tricolporate and exine ornamentation was coarsely reticulate for all species in the two genera. Scanning electron microscopy and morphological observations showed that mature dry seeds of Hypoestes and Rhinacanthus have various sizes and shapes, the surface ornamentations observed were reticulate to cristate, an addition to the tuberculum and papillae. The three Hypoestes species differ in the seed structure which are useful for identification and their high structural diversity provides an important taxonomic value for species differentiation.
