INTRODUCTION
Soil-transmitted helminthiasis (STH) are a major public health problem in Sub-Saharan Africa. In Kenya, the National School Based Deworming Program (NSBDP) was launched in 2012 with a goal of reducing STH prevalence in school-aged children (SAC) to <1%, however monitoring and evaluation results have consistently showed > 20% prevalence in Narok County. We conducted a study to investigate factors associated with STH infections among SAC in Narok County.
METHODOLOGY
A cross-sectional study was conducted among 514 SAC from five schools in Trans Mara West sub-county, Narok County. The sub-county was selected because it had participating schools within the NSBDP with a high prevalence of STH infection. Participants were selected using systematic random sampling. Stool samples collected from participants were examined for STH eggs using Kato-Katz technique. An open data kit questionnaire was used to collect socio-demographics, household, and STH knowledge information from 139 of the 514 SAC. Descriptive statistics was used to summarize the data, prevalence and mean intensity of infections were calculated, and logistic regression used to determine factors associated with STH infections.
RESULTS
The overall prevalence of any STH infection was 24.6% (95%CI: 21.1-28.6). Trichuris trichiura 14.4% (95%CI: 11.7-17.8), Ascaris lumbricoides 12.5% (95%CI: 9.9-15.7) and hookworm 0%. From multivariable analysis the only factors significantly associated with increased risk of STH infection were, children attending Karda and Nkarano schools with aOR = 5.29 (95%CI: 1.45-19.24); p = 0.011 and aOR = 4.53 (95%CI: 1.29-15.97); p = 0.019 respectively. For A. lumbricoides, children attending Nkarano School were associated with a significant risk of infection with aOR = 7.81 (95%CI: 1.81-33.63); p = 0.006.
CONCLUSIONS
Despite the ongoing work of NSBDP, the STH prevalence is still ≥ 20% in Trans Mara West sub-county Narok County, among SAC. This underscores the need for continued annual MDA. Additionally, if possible, drug combinations may effectively manage T. trichiura, the region's most common helminth. The study found a correlation between children attending specific schools and STH infection risk, suggesting the importance of health education and improved water, sanitation, and hygiene practices holistically both in schools and associated catchment areas that can act as STH reservoirs to alleviate the burden of STH.

BACKGROUND
The worldwide distribution and occurrence show that more than 1.8 billion people, accounting for 28% of the global population, are infected with infection due to poor hygiene. The World Health Organization aims to eliminate morbidity from infection in children by 2030 by at least 75%. Surveys in the Pwani Region of Tanzania have shown poor hygienic risk factors due to high population and lack of sufficient toilets/latrines, poor sewage waste disposal, and insufficient clean drinking water that encourages the reproduction, transmission, and reinfection of No study has been conducted in Pwani Region to determine the extent of infection among the population. This research tends to explore more about the status of infection in Kibaha District in the Pwani Region, Tanzania.
METHODS
A cross-sectional study was done on 400 children (170 males and 230 females) who were under the age of 5 years old at Kongowe Health Centre. Collected data for infection measured were analyzed using Microsoft Excel, while data for sociodemographic findings and risk assessment were subjected to bivariate and multivariable analysis using Statistical Package for Social Sciences version 28.0.1.0 software (SPSS Inc., USA) at the level of significance of < 0.05.
RESULTS
Of the 400 children who participated in the laboratory testing of infection, 194 were found positive for infection. Amongst the 194 children who were found to be positive, 4.1%, 38.7%, and 57.2% were found to be in the age group of below 1 year old, 1 to 2, and 3 to 4 years old, respectively. The tabulated responses on the social demographic responses showed that 81.8% of the responses at = 0.041 and 80.6% at = 0.101 knew that infection is acquired from faeces and uncooked food, respectively, as 61.8% at = 0.132 and 63.2% at = 0.085 respondents did not accept that soil and dirty water, respectively, were not sources of infection. At = 0.612 and = 0.022, 64% and 91.2% of the respondents showed the importance of using latrines/toilets and washing fruits, respectively. Further results showed that 69.8% and 37.6% of the respondents reacted with no importance of washing hands with soap after using a toilet/latrine and no need to treat or boil water before drinking, respectively.
CONCLUSIONS
infection has a high prevalence in infants of the Kibaha District of Tanzania, especially in Kongowe village. The infection is dominant in males compared to female children. The prevalence is due to risk factors such as inadequate sanitation, low level of education, knowledge, and awareness of prevention strategies.

BACKGROUND
Appendicitis is one of the most common causes of acute abdominal surgeries. The importance of parasitic etiologies in the pathogenesis of appendicitis is not well known in appendectomy specimens on a large scale in southwestern Iran. The current study aimed to retrospectively assess the demographic data and histopathological records of appendicitis in a 28-year period in Fars province, southwestern Iran.
MATERIALS AND METHODS
Histopathological records of 13,013 patients who had undergone surgeries for appendicitis at Dr. Ali Shariati Hospital, affiliated with the Fasa University of Medical Sciences from December 1993 to January 2021 were reviewed and data concerning the patients' demographic data and histopathological records were retrieved from each record. More than 6800 archived microscopic glass slides were also reviewed.
RESULTS
From a total of 13,013 histopathological records of surgical excisions of appendicitis that were reviewed over a 28-year period, 8,189 (62.9%) were male and 4,842 (37.1%) were female. Patients' age ranged from 2 to 98 years, with a mean age of 24.68±19.87 years. The most common inflammatory changes were 5,687 (43.7%), 1,228 (9.4%), 670 (5.1%), 522 (4%), and 363 (2.8%) cases of acute appendicitis, suppurative appendicitis, early acute appendicitis, gangrenous appendicitis, and perforated appendicitis respectively. Microscopically, no viral inclusions, fungal elements, and histopathologic findings of bacterial causes were found. Parasitic infections such as helminthiasis were detected in 74 (0.6%) cases aged from 6 to 63. Enterobiasis (Syn. oxyuriasis, pinworm infection) accounted for 73 (98.6%) of the 74 helminthiases, while ascariasis accounted for 1 (1.4%). Out of 74 cases, 29 (39.2%) showed evidence of appendicitis.
CONCLUSION
The results suggest that although parasitic agents are minor causes of appendicitis, these agents should be kept in mind during differential diagnosis. However, whether every parasitic infection leads to appendicitis is controversial.

BACKGROUND
Food-borne infections continue to be a major public health problem at the international level. The issue becomes more serious in developing countries like Ethiopia.
OBJECTIVE
This study aimed to examine the prevalence of and species and intestinal parasites, as well as antimicrobial resistance patterns and associated factors among food handlers at the University of Gondar cafeteria in northwest Ethiopia.
METHODS
An institutional-based cross-sectional study was conducted from February to June 2021 in the University of Gondar cafeterias. Data related to the socio-demographic characteristics and hygienic practices of study participants were collected using structured questionnaires. A total of 290 stool samples were collected from food handlers. Culture and conventional biochemical tests were used to isolate the and the species. Wet mount, Formol-ether concentration, and Kato Katz techniques were applied to identify intestinal parasites. Additionally, drug susceptibility tests were performed using the disk diffusion method. Statistical analysis was done using SPSS version 26.
RESULTS
Of 290 food handlers' stool samples analyzed, Twenty-seven 27 (9.3%) were positive for both and species. The prevalence of and species was 16 (5.5%) and 11 (3.8%), respectively. Most of the isolated pathogens were resistant to tetracycline 19 (70.4%), and trimethoprim/sulphamethoxazole 19 (70.4%). The overall rate of multi-drug resistant and isolate was 59.3%. Besides, Fifty-seven 57 (19.7%) of the participants were positive for one or more intestinal parasites. The most prevalent intestinal Parasitosis was 22 (7.6%), followed by 13 (4.5%), and 11 (3.8) not washing hands after using the toilet (AOR: 4.42, 95% CI: 1.57, 10.56), and consuming unpasteurized milk (AOR: 3.14, 95% CI: 1.65, 3.96), were factors significantly associated with the prevalence of Salmonella, and Shigella infection. Similarly, not washing hands after using the toilet (AOR: 2.19, 95% CI: 1.0, 1.4), and consuming unpasteurized milk (AOR: 10.4, 95% CI: 3.8, 28.8), were factors significantly associated with the prevalence of intestinal parasites infection.
CONCLUSION
The prevalence of intestinal parasites, , and species was high. Therefore, it is imperative to implement a public health policy that includes ongoing microbiological surveillance.

. Soil-transmitted helminth (STH) infections are a common global health issue that affects underprivileged communities without adequate access to clean drinking water, sanitation, and hygiene. is the main species that infects humans. Among varied presentations, intestinal obstruction is common among children. Early detection of intestinal obstruction due to STH is critical to prevent severe complications. Here, we present the case of a 10-year-old child with acute intestinal obstruction due to roundworms. . A 10-year-old boy presented to the emergency department with recurrent abdominal pain, distention, and vomiting for three months with signs of peritonitis on examination. CT scan of the abdomen revealed roundworms in the distal ileum and a cocoon formed by adhesions of small bowel loops. Intraoperatively, worm balls were found in the proximal jejunum and ileum, causing small bowel obstruction, and a diseased segment of ileum had to be resected. The worms were removed, and an ileostomy was created. The patient was treated with albendazole and intravenous antibiotics such as ceftriaxone and metronidazole. An early closure of ileostomy was performed after 20 days. Histopathology showed roundworm eggs in the appendix and small bowel mucosa. . infestation is a common cause of intestinal obstruction in children, and early detection is critical for avoiding severe complications. Prompt and appropriate treatment with antihelminthics and antibiotics is necessary to achieve a good outcome. In rare cases, surgical intervention may be required to treat intestinal obstruction caused by STH infections. In conclusion, the prevalence of STH infections highlights the need for public health interventions, such as improving access to clean water, sanitation, and hygiene, and for early detection and treatment to prevent severe complications such as intestinal obstruction.

Ascariasis is a common helminthic infection, especially in India. Though it is known to inhabit the jejunum of the small intestine, it may invade the hepato-biliary and pancreatic ducts, causing a spectrum of clinical manifestations. We present a case of idiopathic recurrent acute pancreatitis in a 61-year-old female patient who was later diagnosed with pancreatic ascariasis using endoscopic ultrasound. This emphasizes the possibility of ascariasis as one of the causes of acute pancreatitis and the use of endoscopic ultrasound as an initial diagnostic tool for the evaluation of idiopathic acute pancreatitis.

BACKGROUND
Soil-transmitted helminthic (STH) infections are the leading cause of stunting among children. To lessen the burden, the World Health Organization (WHO) recommended a periodic deworming program through the use of single-dose therapy in the endemic regions. Therefore, the purpose of this study was to synthesize evidence about the efficacy of anthelminthic drugs against STH infections among preschool and school-age children.
METHODS
The Preferred Reposting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria were followed in this study. Relevant electronic databases, including PubMed, Scopus, Embase, DOAJ, Science Direct, the WHO Clinical Trials.gov library, Google Scholar, and AJOL databases, were searched for relevant publications. Randomized controlled trials (RCTs) and non-randomized interventional studies focused on the efficacy of albendazole and mebendazole against STHs in children were included in the study. Review Manager was used to analyze the data. A random effects model was used to obtain the pooled estimated efficacy. To evaluate heterogeneity, the I test and Cochrane Q (χ) were employed. The risk of publication bias was investigated using Egger's test and the funnel plot. The protocol of this review was registered at the PROSPERO international prospective register of systematic reviews (CRD42023401196).
RESULTS
Of the 69 publications selected for the systematic review, 66 with complete data were included in the meta-analysis. Single doses of albendazole and mebendazole have shown satisfactory efficacy [egg reduction rate (ERR)] against Ascaris lumbricoides [95.54% (95% CI: 88.75-102.34%) and 98.69% (95% CI: 97.68-99.65%), respectively. The effectiveness of these two drugs against Trichuris trichiura and hookworms was comparatively low (< 80% ERR), except for albendazole, which showed high ERRs [93.44% (95%CI: 92.39-94.49%)] against hookworms. The cure rate (CR) of albendazole against T. trichiura, A. lumbricoides, and hookworms were 50.8%, 91.3%, and 78.32%, respectively. Likewise, mebendazole showed CRs of 48.15%, 92.8%, and 49.32% against T. trichiura, A. lumbricoides, and hookworms, respectively. Subgroups such as studies conducted after 2000, diagnostic type (McMaster), and longer follow-up weeks significantly reduced the efficacy of the two drugs against T. trichura. While the combination of albendazole or mebendazole with other drugs and RCT showed significantly improved efficacy against T. trichura. The count of eggs per gram of stool (EPG) was identified as one of the variables that negatively and significantly influenced the efficacy of albendazole or mebendazole against A. lumbricoides.
CONCLUSION
Despite the wide range of ERRs and CR reported in the different articles included in this review, the pooled estimated efficacy of albendazole and mebendazole against STHs falls in the satisfactory category of WHO recommendations. Further evaluation of the combination of anthelminthic drugs as a preventive chemotherapy option and routine drug efficacy testing are necessary to prevent the emergence and widespread use of drug-resistant STHs.

Parasitic infections continue to be a burden for developing countries-the lack of hygiene measures and clean water results in dangerous scenarios that can lead to challenging problems. Most infections are usually mild; nonetheless, in rare cases in endemic regions, they can migrate to the bile duct and cause severe complications requiring surgery. We present the case of a 43-year-old woman who had severe cholangitis due to . The worm migrated from the bowel and obstructed the bile duct; after surgery, the patient fully recovered.

Tropomyosin (TM) is a pan-allergen with cross-reactivity to arthropods, insects, and nematodes in tropical regions. While IgE epitopes of TM contribute to sensitization, T-cell (MHC-II) epitopes polarize the Th2 immune response. This study aimed to identify linear B and T consensus epitopes among house dust mites, cockroaches, , shrimp, and mosquitoes, exploring the molecular basis of cross-reactivity in allergic diseases. Amino acid sequences of Der p 10, Der f 10, Blo t 10, Lit v 1, Pen a 1, Pen m 1, rAsc l 3, Per a 7, Bla g 7, and Aed a 10 were collected from Allergen Nomenclature and UniProt. B epitopes were predicted using AlgPred 2.0 and BepiPred 3.0. T epitopes were predicted with NetMHCIIpan 4.1 against 10 HLA-II alleles. Consensus epitopes were obtained through analysis and Epitope Cluster Analysis in the Immune Epitope Database. We found 7 B-cell epitopes and 28 linear T-cell epitopes binding to MHC II. A unique peptide (residues 160-174) exhibited overlap between linear B-cell and T-cell epitopes, highly conserved across tropomyosin sequences. These findings shed light on IgE cross-reactivity among the tested species. The described immuno-informatics pipeline and epitopes can inform in vitro research and guide synthetic multi-epitope proteins' design for potential allergology immunotherapies. Further in silico studies are warranted to confirm epitope accuracy and guide future experimental protocols.

OBJECTIVES
Kenya has implemented a national school-based deworming program, which has led to substantial decline in the prevalence of soil-transmitted helminths (STHs), although some pockets of infections remain. To effectively design an STH control program that leads to significant reductions of there is a need to understand the drivers of persistent infection despite ongoing treatment programs.
METHODS
This study was conducted between July and September 2019 at the south coast of Kenya, using a two-stage sampling design. First, a school-based cross-sectional survey was conducted in 2265 randomly selected school children from selected schools in areas known to be endemic for . After this, we conducted a nested case-control study wherein all children positive for (142) were matched to 148 negative controls based on age and village. A household survey was then conducted with all household members of cases and controls. In addition, a subsample of 116 children found to be infected with were followed up to assess the efficacy of albendazole at day 21 post-treatment. The predictors of presence of were investigated through multilevel logistic regression, considering clustering of infection.
RESULTS
Overall, 34.4% of the children were infected with at least one STH species; was the most common (28.3%), 89.1% of those with had light-intensity infections. The prevalence of was significantly higher in male children and was positively associated with younger age and number of people infected with in a household. The parasitological cure rate and egg reduction rate of were 35% and 51%, respectively. Other STHs identified were hookworm (9.6%) and (5.7%).
CONCLUSIONS
remains a significant public health challenge in the study area with albendazole treatment efficacy against the parasite, remaining lower than the World Health Organization-recommended thresholds. Because of the observed focal transmission of in the current area, control efforts tailored to local conditions and targeting lower implementation units should be used to achieve optimal results on transmission.
