RESUMO

We detected malaria vector Anopheles stephensi mosquitoes in the Al Hudaydah governorate in Yemen by using DNA sequencing. We report 2 cytochrome c oxidase subunit I haplotypes, 1 previously found in Ethiopia, Somalia, Djibouti, and Yemen. These findings provide insight into invasive An. stephensi mosquitoes in Yemen and their connection to East Africa.

RESUMO

BACKGROUND: Cervical cancer (CxCa), although preventable, is still among the most prevalent cancers in women. Mortality from this cancer is high, especially in low-income countries where preventive strategies are often lacking. We studied the knowledge, attitudes, and practices regarding CxCa among Yemeni women. METHODS: This cross-sectional study was conducted in 2019 among 399 women in five major hospitals in Sanaa, the capital city of Yemen. Data were collected through face-to-face interviews using structured questionnaires. We used logistic regression models to analyze the likelihood of hearing about CxCa, believing that CxCa is treatable and preventable, awareness of the Pap smear test, and ever having this test, in relation to participant's age, education level, working outside the household, and family history of CxCa. RESULTS: Only 66.7% of the women had heard of CxCa. Women with higher education, working outside the household, and with a family history of CxCa were more likely to be aware of CxCa. Working outside the household was the only variable related to a higher likelihood of knowing that CxCa is a treatable and preventable. Furthermore, women with a family history of CxCa were more likely to have knowledge about Pap smear test and were more likely to have Pap smear test in the past. CONCLUSION: This study identified a low awareness of CxCa and its prevention among Yemeni women. In order to reduce the burden of CxCa in Yemen and save women's lives, it is necessary to raise women's awareness of this disease, especially among those with lower education and those not involved in work outside their homes.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) is highly contagious and causes a series of health problems, particularly in Yemen, which has a fragile healthcare system and cannot handle public health emergencies. AIMS: This analysis aimed to determine the epidemiological status of COVID-19 in the Taiz governorate between April 2020 and December 2023. METHODS: A retrospective study based on surveillance data from the Taiz governorate was used. The required data were gathered from the Ministry of Health and Population in Aden and analyzed using SPSS. RESULTS: Out of 5826 suspected of COVID-19 cases, 1933 (33.18%) cases were positive for COVID-19 infection. The high rates of COVID-19 cases were reported at 35.40% in males, 37.80% in people aged 35-44 years, 47.20% in 2020, 72.73% in Dhubab district, and 27.78% in March 2021. The overall incidence rate of cases was reported at 6.2 per 10,000 people in Taiz governorate (8.85 in males and 3.80 in females). In addition, the high incidence rate of COVID-19 was observed among age groups ≥ 65 years, in 2021, and in Al-Mukha districts. In total, the rate of fatality cases was 14.12%, the higher rate of fatality cases was 15.46% among males and 32.23% among individuals aged ≥ 65 years, and 26.97% in 2020. CONCLUSION: In this finding, the incidence rate of COVID-19 is high. It is necessary to increase the public's awareness of the transmission and prevention methods of COVID-19, as well as implement appropriate strategies to protect populations from infectious diseases.

RESUMO

BACKGROUND: The outbreaks of circulating Vaccine Derived Polio Viruses (cVDPVs) have emerged as a major challenge for the final stage of polio eradication. In Yemen, an explosive outbreak of cVDPV2 was reported from August 2021 to December 2022. This study aims to compare the patterns of cVDPV2 outbreak, response measures taken by health authorities, and impacts in southern and northern governorates. METHOD: A retrospective descriptive study of confirmed cases of VDPV2 was performed. The data related to cVDPV2 as well as stool specimens and environmental samples that were shipped to WHO-accredited labs were collected by staff of surveillance. Frequencies and percentages were used to characterize and compare the confirmed cases from the southern and northern governorates. The average delayed time as a difference in days between the date of sample collection and lab confirmation was calculated. RESULTS: The cVDPV2 was isolated from 227 AFP cases reported from 19/23 Yemeni governorates and from 83% (39/47) of environmental samples with an average of 7 months delayed from sample collection. However, the non-polio AFP (NPAFP) and adequate stool specimen rates in the north were 6.7 and 87% compared to 6.4 and 87% in the south, 86% (195) and 14%(32) out of the total 227 confirmed cases were detected from northern and southern governorates, respectively. The first and second cases of genetically linked isolates experienced paralysis onset on 30 August and 1st September 2021. They respectively were from Taiz and Marib governorates ruled by southern authorities that started vaccination campaigns as a response in February 2022. Thus, in contrast to 2021, the detected cases in 2022 from the total cases detected in the south were lower accounting for 22% (7 of 32) of compared to 79% (155 of 195) of the total cases the north. CONCLUSION: A new emerging cVDPV2 was confirmed in Yemen. The result of this study highlighted the impact of vaccination campaigns in containing the cVDPV2 outbreak. Maintaining a high level of immunization coverage and switching to nOPV2 instead of tOPV and mOPV2 in campaigns are recommended and environmental surveillance should be expanded in such a risky country.

RESUMO

BACKGROUND: Effective management of antiretroviral therapy (ART) is crucial in combating the global HIV pandemic. This study, the first of its kind in Yemen, investigates the rate and determinants of switching from first-line to second-line ART among people living with HIV (PLWH) in Aden City, Yemen. METHODS: A retrospective cohort study was conducted using data from PLWH who started first-line ART at Al-Wahda Hospital from 2007 to May 2022. PLWH in prevention of mother-to-child transmission (PMTCT) programs, those already on second-line ART at enrollment, and those with less than 3 months of follow-up were excluded. Cumulative incidence curves and multivariable proportional hazards models were used to identify factors associated with switching, considering death and loss to follow-up as competing risks. Analyses were carried out using IBM SPSS version 26. RESULTS: Out of 149 PLWH, 18 (12.1%) switched to second-line ART with a cumulative incidence rate of 1.8 per 100 person-years. Significant factors for switching included being older than 33 years (HR: 1.45, 95% CI: 1.12-1.89), having WHO stage 3 disease (HR: 1.58, 95% CI: 1.21-2.06), and being on a TDF-FTC-EFV-based first-line regimen (HR: 1.35, 95% CI: 1.03-1.77). This switching rate is consistent with rates observed in other resource-limited settings, indicating it is neither exceptionally high nor low compared to similar contexts​. CONCLUSIONS: The study highlights key factors associated with switching to second-line ART in Yemen, emphasizing the need for targeted interventions and continuous monitoring to enhance treatment outcomes. These findings are consistent with regional data from other resource-limited settings.

RESUMO

BACKGROUND: The current cancer epidemiological profile in Yemen suffers from a lack of locally representative data and resources, posing a challenge in determining the real incidence, prevalence, survival and mortality rates, particularly data extracted from national hospitals. This study aims to provide a comprehensive overview of the cancer burden and trends in Yemen for 2020, including incidence and mortality rates. METHODS: The current study provides cancer statistics and their trends in Yemen, including incidence and mortality, in 2020 by using descriptive statistics. The data was obtained using the Global Cancer Observatory (GCO) 2020 online database. RESULTS: According to the (GCP) database in 2020, the crude incidence rate (CIR) of all cancers in Yemen was 55.2 per 100.000. The age-standardized rate (ASR) was 97.0 per 100.000, and the cumulative risk (0-74) was 22.0 per 100.000. The age-standardized rate (ASR) was 76.5 per 100.000, and the cumulative risk (0-74) was 19.6 per 100.000. Furthermore, the crude mortality rate (CIR) of all cancers was 40.6 per 100.000. Breast cancer was most prevalent in Yemen across all age groups and genders (31.1%), followed by colorectal cancer (7.7%) and leukemia (5.7%). Breast cancer also ranked as the primary cause of mortality at an estimated percentage of 13.5%, followed by colorectal cancer (8.8%) and stomach cancer (7.1%). CONCLUSION: Cancer has become a significant life-threatening illness in Yemen with an increase in the disease burden of breast cancer in women. Furthermore, leukemia in children and colorectal cancer in both sexes have experienced a more significant burden as well. Therefore, it is imperative for initiatives for cancer control and prevention to be prioritised at national and regional levels.

RESUMO

BACKGROUND: In Yemen, morbidity and malnutrition are major public health problems. The Community Health and Nutrition Volunteers (CHNVs) program was launched to tackle these problems through providing services to mothers and their children residing in remote villages. Since establishment of the CHNVs program in Yemen, its outcome has never been evaluated. Therefore, the aim of this study was to assess the role of CHNVs in improving the immunization, morbidity and nutritional status of infant and young children (IYC). METHODS: A comparative cross-sectional study design was conducted in Al-Maghrabah and Bani-Qais districts, Hajjah governorate. It was carried out between January and April 2023. A three-stage cluster sampling method was used. A total of 926 IYC with their mothers were interviewed using a pre-tested questionnaire. SPSS 26 was used for data analysis. The multinomial logistic regression and chi-square or fisher exact tests were used to compare the vaccination, morbidity and nutritional status of IYC between the volunteer and non-volunteer villages. Odds Ratio (OR) with 95% Confidence Interval (CI) were calculated. A p value < 0.05 was considered statistically significant. RESULTS: The IYC in volunteer villages were more likely to be fully or partially vaccinated compared to those in non-volunteer villages [OR = 2.3, 95% CI: 1.5-3.7, p < 0.0001, and OR = 1.9, 95% CI: 1.3-2.8, p = 0.001, respectively]. The specific coverage rates for BCG, and the 1st and 2nd doses of OPV/Pentavalent/Pneumo/Rota vaccines were significantly higher in the volunteer compared to non-volunteer villages [(OR = 1.8, 95% CI: 1.3-2.5, p < 0.0001), (OR = 1.5, 95% CI: 1.2-2.1, p = 0.003), and (OR = 1.5, 95% CI: 1.2-2.0, p = 0.002), respectively]. Moreover, the prevalence of diarrhea and fever among IYC was significantly lower in the volunteer compared to non-volunteer villages [(OR = 0.7, 95% CI: 0.5-0.9, p = 0.004) and (OR = 0.7 95% CI: 0.5-0.9, p = 0.045), respectively]. CONCLUSIONS: The study found that CHNVs play a significant role in improving vaccination status and the coverage rate for BCG, and 1st and 2nd doses of OPV/Pentavalent/Pneumo/Rota vaccines, and reducing the prevalence of diarrhea and fever among IYC in their villages compared to non-volunteer villages, in Hajjah governorate. Future follow-up study and expansion to other settings in different governorates is recommended.

RESUMO

Cutaneous leishmaniasis (CL), a neglected tropical disease, is a major public health concern in Yemen, with Leishmania tropica identified as the main causative agent. This study aims to investigate the occurrence and distribution of Leishmania parasites in domestic and wild animals in CL endemic areas in the western highlands of Yemen. A cross-sectional study was conducted in the Utmah District of western Yemen. Blood and skin scraping specimens were collected from 122 domestic and wild animals and tested for the Leishmania DNA using internal transcribed spacer 1 (ITS1) nested polymerase chain reaction. Phylogenetic analyses were performed on 20 L. tropica sequences obtained from animals in this study and 34 sequences from human isolates (collected concurrently from the same study area) retrieved from the GenBank. Overall, L. tropica was detected in 16.4% (20/122) of the examined animals, including 11 goats, two dogs, two bulls, one cow, one donkey, one rabbit, one rat and one bat. None of the examined cats and sheep was positive. The animal sequences were segregated into four different L. tropica haplotypes, with the majority of the animal (15/20) and human (32/34) sequences composed of one dominant haplotype/genotype. These findings represent the first confirmed evidence of natural L. tropica infections in different kinds of domestic and wild animals in western Yemen, suggesting these animals potentially have a role in the transmission of CL in Yemen. Therefore, a One Health approach is required for the effective prevention and control of this devastating disease among endemic populations.

RESUMO

A precursor for effective root canal treatment (RCT) is a complete understanding of the internal anatomy of teeth. In this study, the authors aimed to classify the root canal morphology of anterior teeth in the Yemeni population and identify gender-based variations among them. In addition, the symmetry among adjacent quadrants was also evaluated. Cone beam computed tomography (CBCT) scans of 2935 anterior teeth, 1502 maxillary, and 1433 mandibular were analyzed for root canal morphology and symmetry. Comparison between groups and among different genders was done using the Chi-square test. All the maxillary teeth were single-rooted and had a predominantly 1TN1 (Vertucci Type I) canal morphology. In addition to 1TN1, the presence of 1TN1-2-1 (Vertucci type III) and 1TN1-2-1-2-1 (not classified NC according to Vertucci) morphologies were noticed in the maxillary canines. Among the mandibular anteriors, the canal morphologies identified include 1TN1 in majority of the scans followed by 1TN2-1 (Vertucci II), 1TN1-2-1, 1TN1-2 (Vertucci V), 1TN1-2-1-2 (Vertucci VII) was seen only in incisors and newer canal types like 1TN2-1-2-1 (NC Vertucci) and 1TN1-2-1-2-1 (NC Vertucci) was seen in canines and lateral incisors. Two roots were only seen in the mandibular canines and classified as 2TN1-2 (NC Vertucci). Variations in root and root canal morphologies were seen among both genders. However, the results were not significant. All the maxillary teeth except 0.8% were bilaterally symmetrical. In mandible, symmetry ranged between 84.5 and 86.5%. In conclusion, single-rooted teeth with 1TN1 classification are most commonly seen in all the anterior teeth. Gender-based differences were non-significant, and bilateral symmetry was high. Ahmed et al. classification could precisely represent the root canal morphology in two rooted teeth.

RESUMO

OBJECTIVES: This study aimed to comprehensively analyze the prevalence and influencing factors of Zygomatic Air Cell Defects (ZACD) among pediatric and adolescent populations in Saudi Arabia and Yemen. MATERIALS AND METHODS: A cross-sectional retrospective study was conducted, utilizing digital panoramic radiographs of dental outpatients aged 6 to 18 years. The data were collected from registered digital databases of dental clinics in Al-Qassim, Saudi Arabia, and an oral and maxillofacial radiology center in Sana'a, Yemen, covering the period from July 2018 to September 2022. The radiographs were evaluated based on inclusion and exclusion criteria, and ZACD was assessed using standardized descriptions. Statistical analysis, including logistic regression, was employed to examine the impact of the associated factors. RESULTS: The study encompassed a total of 3,169 participants, revealing an overall ZACD prevalence of 28.5%. Age emerged as a significant predictor (p ≤ 0.0001), with the likelihood of ZACD increasing as the age of the individual advances. Gender and geographic region did not exhibit statistically significant differences in ZACD prevalence. CONCLUSION: This study provides crucial insights into the prevalence of Zygomatic Air Cell Defects among pediatric and adolescent populations in Saudi Arabia and Yemen. It underscores the prevalence of ZACD and the notable influence of age on its occurrence. Additionally, the research challenges prior notions of gender and regional variations in ZACD prevalence, emphasizing the complexity of the factors involved. Early detection is essential to avoid unwanted complications during any surgical intervention in this area.

RESUMO

BACKGROUND: Tibial shaft fractures are common injuries that can be treated with various methods, including interlocked intramedullary nail (IMN). However, there is limited data on the clinical outcomes of IMN for tibial shaft fractures in Yemen. OBJECTIVE: To evaluate the clinical outcomes of primary IMN for tibial shaft fractures in Yemen. METHODS: This was a prospective study of 134 patients who underwent primary IMN for tibial shaft fractures et al.-Thawra Modern General Hospital in Sana'a, Yemen, between June 2016 and June 2020. The patients were between 18 and 70 years old, and the fractures were classified according to the AO classification system. The fractures were treated with IMN using a standard technique. The patients were followed up for a minimum of 2 years. The outcome measures included union time, complications, and functional scores. RESULTS: The mean union time was 17 weeks. The overall complication rate was 18.7%. The most common complications were infection (8.2%), delayed union (6.7%), and nonunion (3.7%). The mean functional scores at the final follow-up were 91.4 for the Knee Society Score and 90.2 for the American Orthopaedic Foot and Ankle Society Score. CONCLUSION: Primary IMN is an effective and reliable method for treating tibial shaft fractures in Yemen, with acceptable union time, complication rate, and functional outcomes.

RESUMO

Immunity to malaria has a major role in controlling disease and pathogenesis with cytokine production being involved in almost every phase of the immune response. The present study aimed to assess hematological variables and to measure plasma levels of TNFα, IFNγ and IL10, their ratios, and their relation to parasitemia among patients with uncomplicated falciparum malaria in Hodeidah, Yemen. Forty patients with uncomplicated P. falciparum monoinfection and 40 healthy age and sex-matched controls were enrolled in the study. Parasitological diagnosis was confirmed, and parasite density was estimated. Plasma cytokine levels, hematologic parameters, and the presence of gametocytes were determined. Results revealed higher TNFα, IFNγ and IL10 in patients than in controls. A relatively higher IL10 production was demonstrated by the significantly lower TNFα/IL10 and IFNγ/IL10 ratios in patients than in controls. TNFα and IL10 correlated positively with parasite density. Lower Hb levels, RBC, lymphocyte and platelet counts, and higher neutrophil and reticulocyte counts were observed in patients compared to controls. Reticulocyte count was higher and IFNγ level was lower in the presence of gametocytes. Conclusively, uncomplicated falciparum malaria is associated with the ability to regulate the production of pro-inflammatory and anti-inflammatory cytokines. This mediates parasite clearance while simultaneously avoiding severe pathology.

RESUMO

BACKGROUND: Declines in global malaria cases and deaths since the millennium are currently challenged by multiple factors including funding limitations, limits of, and resistance to vector control tools, and also recent spread of the invasive vector species, Anopheles stephensi-especially into novel urban settings where malaria rates are typically low. Coupled with general increases in urbanization and escalations in the number of conflicts creating rapid and unplanned population displacement into temporary shelter camps within host urban areas, particularly in the Middle East and sub-Saharan Africa, increased urban malaria is a major threat to control and elimination. METHODS: Entomological monitoring surveys (targeting Aedes aegypti) of water containers across urban areas hosting internally displaced people (IDP) communities in Aden city, Yemen, were performed by The MENTOR Initiative, a non-governmental organisation. As part of these surveys in 2021 23 larvae collected and raised to adults were morphologically identified as An. stephensi. Twelve of the samples were sent to Liverpool School of Tropical Medicine for independent morphological assessment and genetic analysis by sequencing the ribosomal ITS2 region and the mitochondrial COI gene. RESULTS: All twelve samples were confirmed morphologically and by sequence comparison of the single ITS2 and COI haplotype detected to the NCBI BLAST database as An. stephensi. Phylogenetic analysis with comparable COI sequences indicated close relationship to haplotypes found in Djibouti and Ethiopia. CONCLUSION: The study results confirm the presence of An. stephensi in Yemen. Confirmation of the species in multiple urban communities hosting thousands of IDPs living in temporary shelters with widescale dependency on open water containers is of particular concern due to the vulnerability of the population and abundance of favourable breeding sites for the vector. Proactive monitoring and targeted integrated vector management are required to limit impacts in this area of typically low malaria transmission, and to prevent further the spread of An. stephensi within the region.

RESUMO

BACKGROUND: Female genital mutilation/cutting (FGM/C), a violation of human rights, remains common in the coastal areas of Yemen. OBJECTIVE: This study aimed to identify the prevalence of FGM/C and its risk factors among the youngest daughters in families in the Yemeni coastal areas, as well as the knowledge and attitudes of the local population towards FGM/C. METHODS: A cross-sectional survey was conducted among 646 women and 345 men from six districts in three Yemeni coastal governorates between July and September 2020 using a structured questionnaire. Categorical data were described by proportion. The chi-square test was used to identify factors associated with FGM/C. All factors with a p-value of ≤ 0.05 were included in the multivariate analysis. Adjusted odds ratios (AORs) and 95% confidence intervals (CIs) were calculated in the multivariate logistic regression analysis. RESULTS: The prevalence of FGM/C in Yemeni coastal areas was 89.0% (95% CI 84.0%-92.5%) among women and 79.8% (95% CI 73.5%-84.8%) among the youngest daughters in the surveyed families. Nearly two-thirds of women and half of the men recorded a poor knowledge level about the harms of FGM/C. Furthermore, almost two-thirds of both women and men would like to continue the practice of FGM/C. Among women, significant predictors of FGM/C among youngest daughters included advanced maternal age of ≥ 40 years (AOR 7.16, 95% CI 2.73-18.76), mother's desire to continue FGM/C (AOR 8.07, 95% CI 3.64-17.89), and living in a rural area (AOR 3.95, 95% CI 1.51-10.30). Daughters of mothers who did not undergo FGM/C were more protected from FGM/C than those whose mothers had undergone FGM/C (AOR 0.04, 95% CI 0.02-0.09). Among men, the father's desire to continue FGM/C (AOR 15.10, 95% CI 6.06-37.58) was significantly associated with FGM/C among the youngest daughters. CONCLUSION: This study confirmed that FGM/C is still prevalent among communities in Yemeni coastal areas. Thus, community-based interventions with a focus on the rural population are vital to improving the awareness of various harms of FGM/C.

RESUMO

In this article, we describe in detail the health and general living conditions resulting from the ongoing armed conflict in Yemen, including the historical and geopolitical underpinnings. In addition to mere reporting, we use Yemen as a case study to examine the responsibility of bioethicists in general. We find it unacceptable that bioethics neglects the largest humanitarian crisis taking place in the world at the moment as well as the largest Cholera outbreak in history. We argue that bioethicists should do more to address armed conflicts and their resulting basic human rights violations. We end with a few recommendations to prevent such neglect.

RESUMO

BACKGROUND: Respondent-driven sampling (RDS) refers both to a chain-referral sampling method and an analytical model for analysing sampled data. Web-based respondent-driven sampling (webRDS) uses internet-based recruitment coupled with an electronic survey to carry out RDS studies; there is currently no commercially available webRDS solution. We designed and developed a webRDS solution to support a research study aimed at estimating conflict-attributable mortality in Yemen. Our webRDS solution is composed of an existing survey platform (i.e. ODK) and a bespoke RDS system. The RDS system is designed to administer and manage an RDS survey cascade and includes: (1) an application programming interface, (2) a study participant client, and (3) an administrator interface. We report here on the design of the webRDS solution and its implementation. RESULTS: We consulted members of the Yemeni diaspora throughout the development of the solution. Technical obstacles were largely the result of: WhatsApp's policies on bulk messaging and automated messaging behaviour, the inherent constraints of SMS messaging, and SMS filtering behaviour. Language support was straight-forward yet time consuming. Survey uptake was lower than expected. Factors which may have impacted uptake include: our use of consumable survey links, low interest amongst the diaspora population, lack of material incentives, and the length and subject matter of the survey itself. The SMS/WhatsApp messaging integration was relatively complex and limited the information we could send potential participants. CONCLUSION: Despite lower-than expected survey uptake we believe our webRDS solution provides efficient and flexible means to survey a globally diverse population.

RESUMO

Increasing women's knowledge about maternal health is an important step towards empowering them and making them aware of their rights and health status, allowing them to seek appropriate health care. In Yemen, the ongoing conflict has hampered the delivery of health information to women in public health facilities. This study examined rural women's knowledge of, and attitude towards, maternal and child health in Yemen and identified the factors associated with good maternal health knowledge. The study was conducted between August and November 2018. A sample of 400 women aged 15-49 years who had delivered in the 6 months prior to the survey were systematically selected from selected public health facilities in Abyan and Lahj. Women were interviewed using a structured questionnaire to gather data on their demographic and economic characteristics, obstetric history and responses to health knowledge and attitude questions. Women's knowledge level was assessed as poor or good using the mean score as a cut-off. Chi-squared test and multiple logistic regression analysis were used to identify statistically significant factors associated with good maternal health knowledge. The percentage of women who had good knowledge was 44.8% (95% CI: 39.8-49.8). Women's attitude towards maternal health was negative in the areas of early ANC attendance, managing dietary regime and weight during pregnancy, facility delivery, PNC visits, cord care and mother and child health management. Women with primary education, whose husbands had received no formal education, who had their first ANC visit from the second trimester of pregnancy and who had fewer than four ANC visits were more likely to have poor health knowledge. Conversely, those with higher household income and only one child were more likely to have good maternal health knowledge. Overall, women's knowledge on maternal and child health care in rural areas of Yemen was low. Strategies are needed to increase rural women's knowledge on maternal and child health in this conflict-affected setting.

RESUMO

BACKGROUND: Research is an important element in the improvement of the quality of health services provided to the public. It is documented that globally; medical students apply research in their school life. In Hadhramaut University, medical students work on research in groups, and it is an important part of the curriculum. There is a formal assessment of the student's research, but there is still a gap regarding individual viewpoints and challenges faced. This study aimed to assess perception, attitude, and practice toward research among medical students at Hadhramout University. METHODS: This is a cross-sectional descriptive study which was conducted among medical students. This study was undertaken in Hadhramout University in Al-Mukalla district, Yemen, during the academic year 2016-2017. A self-administered pilot-tested questionnaire was used for data collection to assess perception, attitude, and practice toward the research during the educational year 2016-2017. RESULTS: A total of 265 completed responses were received. The majority had a low Knowledge score (72%). However, the majority had a positive attitude toward research (90.9%). Eighty-three students reported participation in research work. However, (44.4%) expressed research interest. Many barriers were highlighted by students including a lack of time (78.4%) and a lack of training in statistics (75.9%). CONCLUSION: The study identified several barriers for undergraduate medical students to undertake research. It is important that these barriers should be addressed in curriculum development, so that students can retain their motivation to engage effectively in research.

RESUMO

BACKGROUND: The "Knowledge, attitude, and practice (KAP)" approach is crucial in health system. Appreciating the current KAP status will reveal the extent of the efficiency of applied health strategies, and subsequently help to determine the appropriate health policy to be employed for improving the health indicators of a given disease/condition, including Oral Cancer (OC). This large-scale cross-sectional study aimed to assess knowledge, attitude, and practice on OC among senior dental students in Yemen. METHODS: A pre-validated online questionnaire was used for data collection. It consisted of a series of close-ended questions on knowledge, attitudes and practices related to OC. Yemeni dental students in clinical levels (4th and 5th years) from nine dental schools based in four major cities were invited to complete the survey. The SPSS Version 28.0 was used for data analysis. Differences by different grouping factors were assessed by Chi-squared and Mann Whitney-U tests, as appropriate. RESULTS: A total of 927 students completed the questionnaire: a response rate of 43%. While the majority identified smoking (93.8%), and smokeless tobacco (92.1%) as potential risk factors of OC, only 76.2% recognized sun exposure as a risk factor for lip cancer and only 50% were aware of old age as a risk factor of OC. Regarding clinical signs of OC, 84.1% reported that OC can present as non-healing ulcer, but only two thirds of the participants recognized that OC can present as a white and/or red lesion. With respect to practices, although 92.1% reported asking their patients regarding oral habits, only 78% reported they regularly carry out a soft tissue examination. Only 54.5% of the participants considered themselves to be well-trained to provide smoking cessation advice, and 21% were confident regarding their knowledge on OC. The 5th year students showed significantly better knowledge and practices than the 4th year students did (p < 0.01). CONCLUSION: The study suggests significant gaps in knowledge, attitudes, and practices of senior dental students in Yemen regarding OC. The findings also underscore the urgent need to improve OC teaching and training of undergraduate dental students, and to provide periodic well-structured continuing professional development activities for dental professionals.

RESUMO

Background: Intestinal parasitic infections in pregnant women have been associated with severe adverse outcomes such as anemia, low birth weight, and mother and fetus morbidity and mortality. This study aimed to determine the prevalence of intestinal parasitic infection and its associated risk factors among pregnant women in Taiz, Yemen. Methods: A cross-sectional study was conducted between July 2022 and January 2023. Sociodemographic and other explanatory variables were obtained via face-to-face interviews using a structured questionnaire. The wet-mount and formol-ether concentration techniques were applied to identify the IPIs. Data were analyzed using SPSS, version 20, and p-values < 0.05 were considered statistically significant. An analysis of descriptive statistics and multivariate logistic regression was conducted. A p-value < 0.05 was deemed statistically significant. The study included a total of 393 pregnant women. Results: Of the 393 pregnant women screened for intestinal parasites, 144 (36.6 %) had at least one parasite. The most common intestinal parasite was Giardia lamblia (12.2 %), followed by Ascaris lumbricoides (10.9 %), Entamoeba histolytica/dispar (7.4 %), Enterobius vermicularis (14.3 %), and Hymenolepis nana (1.8 %). Being a farmer (AOR = 2.7, 95% CI: 1.69-4.26, p = 0:003) and drinking from unsafe water wells, streams, rain, and dams (AOR = 2:6, 95% CI: 1.68-4.25, p ≤ 0:001) were significantly associated with IPIs. Conclusion: Pregnant women in the study area still face a severe health burden due to intestinal parasitic infection. Therefore, it is recommended that health education should be improved, and safe tap water should be provided to pregnant women to reduce the incidence of IPIs.
