ObjectiveSurgical site infections (SSIs) are among the most common healthcare-associated infections occurring following 1%–3% of all surgical procedures. Their rates are the highest following abdominal surgery. They are still associated with increased morbidity and healthcare costs despite the advancement in the medical field. Many risk factors for SSIs following abdominal surgery have been identified. The aim of this study is to comprehensively assess these risk factors as published in peer-reviewed journals.DesignA systematic review was conducted with accordance to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.SettingThe databases for search were PubMed and Cochrane Library, in addition to reference lists. Studies were retrieved and assessed for their quality. Data were extracted in a designed form, and a stratified synthesis of data was conducted to report the significant risk factors.ParticipantsPatients undergoing general abdominal surgery.InterventionThe intervention of general abdominal surgery.Main outcome measuresTo identify and assess the risk factors for SSI following abdominal surgery.ResultsLiterature search yielded 813 articles, and the final screening process identified 11 eligible studies. The total number of patients is 11 996. The rates of SSI ranged from 4.09% to 26.7%. Nine studies were assessed to be of high quality, the remaining two studies have moderate quality. Stratified synthesis of data was performed for risk factors using summary measures (OR/risk ratio, 95% CI, and p value). Male sex and increased body mass index (BMI) were identified as significant demographic risk factors, and long operative time was among the major significant procedure-related risk factors.ConclusionsMale sex, increased BMI, diabetes, smoking, American Society of Anesthesiologists classification of >2, low albumin level, low haemoglobin level, preoperative hospital stay, long operative time, emergency procedure, open surgical approach, increased wound class, intraoperative blood loss, perioperative infection, perioperative blood transfusion, and use of drains are potential independent risk factors for SSI following abdominal surgery.

Background Upper respiratory tract infections (URTIs) are among the most common diagnoses resulting in antibiotic prescriptions. Reducing unnecessary antibiotic use is critical to avoiding irrational use and antimicrobial resistance; one of the top 10 global public health concerns facing humanity. As monitoring and administering therapy for children’s ailments are mostly the responsibility of their parents, their perception will have a significant effect on whether or not it is administered appropriately. Methods This cross-sectional hospital-based study was conducted at 2 major children teaching hospitals (Ibrahim Malik and Jaafar Ibn Auf) in Khartoum, Sudan. A simple random sampling was applied and a questionnaire adapted from a previous study was used to collect the data. Data was analyzed using a statistical package for social sciences (SPSS). Ethical clearance was obtained from the Department of Community Medicine, Faculty of Medicine, University of Khartoum, the ministry of health, and the hospitals in which the study was conducted. Results Two hundred and eleven out of two hundred thirty-nine randomly selected parents participated in the study (response rate of 88.3%). Although, 63.5% of parents were aware that antibiotics should not be administered for every case of fever, only 39.3% of respondents were aware that URTIs are caused by viruses and do not require antibiotic therapy. 60% (60%) believed that antibiotics cure URTI symptoms faster and 70.6% were unaware that inappropriate antibiotic administration leads to bacterial resistance. The most prevalent symptom that prompts parents to seek medical assistance was earache (80.6%), followed by fever and sore throat (68.2% and 64.5%, respectively). When they went to the doctor, 73.3% expected antibiotics to be prescribed, and more than 65% wanted antibiotics to be administered if their child had cold or nasal drainage. Only 28.4% of parents said they never administer antibiotics without consulting a doctor. Conclusions Parents should be educated about the duration of URTIs, the self-limiting nature of such infections in children, and how to use antibiotics safely and effectively. The provision of such knowledge may minimize parents’ fears and concerns regarding URTIs, hence reducing antibiotic use.

Background Plasmodium falciparum malaria is a public health problem worldwide. Malaria treatment policy has faced periodic changes due to emergence of drug resistant parasites. In Sudan chloroquine has been replaced by artesunate and sulfadoxine/pyrimethamine (AS/SP) in 2005 and to artemether–lumefantrine (AL) in 2017, due to the development of drug resistance. Different molecular markers have been used to monitor the status of drug resistant P. falciparum . This study aimed to determine the frequency of malaria drug resistance molecular markers in Southeast Sudan. Methods The samples of this study were day zero dried blood spot samples collected from efficacy studies in the Blue Nile State from November 2015 to January 2016. A total of 130 samples were amplified and sequenced using illumina Miseq platform. The molecular markers included were Pfcrt , Pfmdr1 , Pfdhfr , Pfdhps , Pfk13 , exonuclease and artemisinin resistant (ART‐R) genetic background ( Pfmdr2 , ferroredoxine , Pfcrt and Pfarps 10). Results Resistance markers for chloroquine were detected in 25.8% of the samples as mutant haplotype Pfcrt 72-76 CVIET and 21.7% Pfmdr1 86Y. Pfdhfr mutations were detected in codons 51, 59 and 108. The I C N I double-mutant haplotype was the most prevalent (69%). Pfdhps mutations were detected in codons 436, 437, 540, 581 and 613. The S GEG A triple-mutant haplotype was the most prevalent (43%). In Pfdhfr / Pfdhps combined mutation, quintuple mutation I C N I/S GEG A is the most frequent one (29%). Six of the seven treatment failure samples had quintuple mutation and the seventh was quadruple. This was significantly higher from the adequately responsive group (P < 0.01). Pfk13 novel mutations were found in 7 (8.8%) samples, which were not linked to artemisinin resistance. Mutations in ART‐R genetic background genes ranged from zero to 7%. Exonuclease mutation was not detected. Conclusion In this study, moderate resistance to chloroquine and high resistance to SP was observed. Novel mutations of Pfk13 gene not linked to treatment failure were described. There was no resistance to piperaquine the partner drug of dihydroartemisinin/piperaquine (DHA-PPQ).

Background The present study aimed to evaluate the management of severe malaria at Gezira State hospitals in Sudan by assessing hospital readiness, health care provider knowledge and the care received by severe malaria patients. Methods A cross-sectional descriptive study was performed to assess the severe malaria management practices at hospitals level in Gezira State. The study population included hospitals, health care providers and patients. Data was collected using checklists and structured questionnaires. Results A total of 20 hospitals, 158 health care providers and 370 patients were included in the study. Out of the total hospitals, 95% (19/20) were providing 24 h outpatient services, 65% (13/20) had ICU units, while triage system was found in only 35% (7/20) of hospitals. From all hospitals evaluated, 90% (18/20) were suffering from shortage of staff, especially doctors. About half of the health care providers (46.7%) did not receive severe malaria management training. The average knowledge score among health care providers was 55.4%. Microscopy was available in all hospitals (100%), while rapid diagnostic test, complete blood count and renal function test were available in 15 hospitals (75%). Fever was the most presenting symptom (97.8%) followed by repeated vomiting (51.4%), convulsion in children (24.3%) and prostration in adult (57.9%). Correctly diagnosed patients were 68.9%. Essential tests were done for only 11.1% of patients. Majority of patients (91.7%) were treated with quinine, 5.9% received artemether, while 2.4% were treated with artemether–lumefantrine. Those who received both the correct dose and dosing regimen were 53.8%. The overall compliance to guidelines was 2.2%. Conclusion This study highlights the fact that management of severe malaria at hospital level was suboptimal with serious shortcomings in the different aspects of care particularly in specialized hospitals. Technical staff was inadequate, hospitals were anguish from defective emergency services, and most patients were not treated according to the national guidelines.

Children and adolescents account for a small proportion of confirmed COVID-19 cases, with mild and self-limiting clinical manifestations. The distribution and determinants of COVID-19 among this group in Sudan are unclear. This study used national COVID-19 surveillance data to study the epidemiology of COVID-19 among children and adolescents in Sudan during 2020–2021. A cross-sectional study was performed to estimate the reported incidence of children and adolescents with COVID-19; the clinical features; and the mortality among those who tested positive for COVID-19. A total of 3150 suspected cases of COVID-19 infection fulfilled the study criteria. The majority of cases were above 10 years of age, 52% (1635) were males, and 56% (1765) were asymptomatic. The reported incidence rates of COVID-19 among children and adolescents in Sudan was 1.3 per 10,000 in 2021. Fever, cough, and headache were the most frequent symptoms reported among the suspected cases. The case fatality rate was 0.2%. Binary logistic regression revealed that loss of smell was the most significantly associated symptom with a positive test. We recommend further study to identify risk factors. Additionally, we recommend including these age groups in the vaccination strategy in Sudan.

Background Dengue fever (DF) is now a major concern for world public health. Despite the government's reactionary measures, dengue incidences in Yemen are on the rise. Therefore, having adequate knowledge, a positive mindset, and appropriate dengue management techniques are critical for eradicating dengue. This study aims to evaluate people's knowledge, attitudes, and practices (KAP) about dengue fever (DF) and determine their correlation with sociodemographic factors. Methods This was a cross-sectional facility-based study; participants were selected using a multistage sampling technique out of patients who were seeking healthcare services in Seiyun, Hadhramaut, Yemen. Data was collected using a validated closed-ended questionnaire and analysed using SPSS version 28. Both descriptive and inferential statistics were applied with a considered P value ≤ 0.05 significant in all tests. Results This study included 415 participants. The study found that 98.80% of participants had good knowledge about dengue fever, while 27.2% had good attitudes and 28.4% had good practices. There was a correlation between knowledge scores and educational level (P = 0.008), with university-educated participants displaying the highest mean rankings. Knowledge scores were higher for individuals who had previously contracted dengue (P = 0.003). Participants who received information from social media, healthcare providers, and the neighbouring community had the highest mean scores across all domains (P = 0.001). Conclusion The findings suggest that individual characteristics, such as sex and education, as well as the source of dengue-related information and previous infection, can influence knowledge, attitudes, and practices. Targeted interventions addressing these factors may help improve dengue prevention and control in the community.

Background Preeclampsia is a serious pregnancy-related disease which may lead to adverse health effects to the mother and fetus. Besides many publications on the association of red cell distribution width (RDW) and preeclampsia, there has been no published meta-analysis. This necessitated the present systemic review and met-analysis to assess the RDW in relation to preeclampsia. Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed. Relevant published studies were searched in PubMed, Cochrane library, Google scholar, Scopus, Embase and CINAHL using the term “Preeclampsia OR eclampsia AND red cell distribution width OR red blood cells). Modified Newcastle – Ottawa quality assessment scale was used for critical appraisal of retrieved studies. Pooled Meta logistic regression was computed using OpenMeta Analyst software. Subgroup and meta-regression methods were performed to analyse the heterogeneity. Results Eleven case control studies were included in the met-analyses with a total of 951 cases (preeclampsia) and 2024 controls. The mean (SD) of the RDW level was significantly higher in women with preeclampsia compared to controls [15.10 (2.48) % vs. 14.26(1.71) %, P < 0.001]. The mean difference was 0.85, 95% CI = 0.26–1.43. Due to a high heterogeneity (I2 = 90.45, P < 0.001), the continuous random effect model was used. Eight studies compared RDW level in the mild (N = 360) with severe cases (N = 354) of preeclampsia. The RDW level was significantly higher in women with severe preeclampsia compared to those with mild preeclampsia [15.37 (2.48) % vs. 14.037(1.79) %, P < 0.001]. The mean difference was 1.07, 95% CI = 0.45–1.70. Since there is a high heterogeneity [I2 = 76.67, P < 0.001], the continuous random effect model was used. Through the met-regression model, except for the region of the study (P < 0.001), none of investigated variables (age, parity, quality of the study) was significantly associated with the investigated heterogeneity. The outliers (3studies) were removed to reduce the heterogeneity. The pooled meta-analysis of the remaining 8 studies showed a significant difference in the RDW between preeclamptic women compared with the controls. The mean difference was 0.93, 95% CI = 0.56–1.31, P < 0.001. Because of heterogeneity [I2 = 69.6, P = 0.002], the continuous random effect model was used. Conclusion RDW level was significantly higher in women with preeclampsia compared to controls. Similarly, women with severe preeclampsia had significantly higher RDW than those with the mild form.

Background Artemisinin-based combination therapy (ACT), together with other control measures, have reduced the burden of falciparum malaria in sub-Saharan countries, including Sudan. Sudan adopted ACT in 2004 with a remarkable reduction in mortality due to falciparum malaria. However, emergence of resistance to the first-line treatment artesunate and sulfadoxine/pyrimethamine (AS/SP) has created new challenges to the control of malaria in Sudan. A search for an alternative drug of choice for treating uncomplicated malaria has become inevitable. The objective of this study was to evaluate the therapeutic efficacies of dihydroartemisinin/piperaquine (DHA–PPQ) and AS/SP in an area of unstable transmission in Blue Nile State, Sudan in 2015–16. Methods A total of 148 patients with uncomplicated malaria were recruited in the study from November 2015 to end of January 2016. Seventy-five patients received DHA–PPQ while 73 received AS/SP. Patients were monitored for clinical and parasitological outcomes following the standard WHO protocol for a period of 42 days for DHA–PPQ and 28 days for AS/SP; nested PCR (nPCR) was performed to confirm parasite re-appearance from day 7 onwards. Results Fifty-five patients completed the DHA–PPQ arm protocol with success cure rate of 98.2% (95% CI 90.3–100%) and one late clinical failure 1.8% (95% CI 0.0–9.7%). The AS/SP showed adequate clinical and parasitological response (ACPR) of 83.6% (95% CI 71.9–91.8%), early treatment failure was 1.6% (95% CI 0.0–8.8%) and late parasitological failure (LPF) was 14.8% (95% CI 7–26.2%). The respective PCR uncorrected LPF was 20%. Conclusion DHA–PPQ is an efficacious ACT and candidate for replacement of first-line treatment in Sudan while AS/SP showed high treatment failure rate and must be replaced.

Scale-up of insecticide-based interventions has averted more than 500 million malaria cases since 2000. Increasing insecticide resistance could herald a rebound in disease and mortality. We aimed to investigate whether insecticide resistance was associated with loss of effectiveness of long-lasting insecticidal nets and increased malaria disease burden. This WHO-coordinated, prospective, observational cohort study was done at 279 clusters (villages or groups of villages in which phenotypic resistance was measurable) in Benin, Cameroon, India, Kenya, and Sudan. Pyrethroid long-lasting insecticidal nets were the principal form of malaria vector control in all study areas; in Sudan this approach was supplemented by indoor residual spraying. Cohorts of children from randomly selected households in each cluster were recruited and followed up by community health workers to measure incidence of clinical malaria and prevalence of infection. Mosquitoes were assessed for susceptibility to pyrethroids using the standard WHO bioassay test. Country-specific results were combined using meta-analysis. Between June 2, 2012, and Nov 4, 2016, 40 000 children were enrolled and assessed for clinical incidence during 1·4 million follow-up visits. 80 000 mosquitoes were assessed for insecticide resistance. Long-lasting insecticidal net users had lower infection prevalence (adjusted odds ratio [OR] 0·63, 95% CI 0·51–0·78) and disease incidence (adjusted rate ratio [RR] 0·62, 0·41–0·94) than did non-users across a range of resistance levels. We found no evidence of an association between insecticide resistance and infection prevalence (adjusted OR 0·86, 0·70–1·06) or incidence (adjusted RR 0·89, 0·72–1·10). Users of nets, although significantly better protected than non-users, were nevertheless subject to high malaria infection risk (ranging from an average incidence in net users of 0·023, [95% CI 0·016–0·033] per person-year in India, to 0·80 [0·65–0·97] per person year in Kenya; and an average infection prevalence in net users of 0·8% [0·5–1·3] in India to an average infection prevalence of 50·8% [43·4–58·2] in Benin). Irrespective of resistance, populations in malaria endemic areas should continue to use long-lasting insecticidal nets to reduce their risk of infection. As nets provide only partial protection, the development of additional vector control tools should be prioritised to reduce the unacceptably high malaria burden.

Background Malaria remains a major public health problem especially in sub-Saharan Africa. Despite the efforts exerted to provide effective anti-malarial drugs, still some communities suffer from getting access to these services due to many barriers. This research aimed to assess the feasibility and acceptability of home-based management of malaria (HMM) strategy using artemisinin-based combination therapy (ACT) for treatment and rapid diagnostic test (RDT) for diagnosis. Methods This is a study conducted in 20 villages in Um Adara area, South Kordofan state, Sudan. Two-thirds (66%) of the study community were seeking treatment from heath facilities, which were more than 5 km far from their villages with marked inaccessibility during rainy season. Volunteers (one per village) were trained on using RDTs for diagnosis and artesunate plus sulphadoxine-pyrimethamine for treating malaria patients, as well as referral of severe and non-malaria cases. A system for supply and monitoring was established based on the rural health centre, which acted as a link between the volunteers and the health system. Advocacy for the policy was done through different tools. Volunteers worked on non-monetary incentives but only a consultation fee of One Sudanese Pound (equivalent to US$0.5). Pre- and post-intervention assessment was done using household survey, focus group discussion with the community leaders, structured interview with the volunteers, and records and reports analysis. Results and discussion The overall adherence of volunteers to the project protocol in treating and referring cases was accepted that was only one of the 20 volunteers did not comply with the study guidelines. Although the use of RDTs seemed to have improved the level of accuracy and trust in the diagnosis, 30% of volunteers did not rely on the negative RDT results when treating fever cases. Almost all (94.7%) the volunteers felt that they were satisfied with the spiritual outcome of their new tasks. As well, volunteers have initiated advocacy campaigns supported by their village health committees which were found to have a positive role to play in the project that proved their acceptability of the HMM design. The planned system for supply was found to be effective. The project was found to improve the accessibility to ACTs from 25% to 64.7% and the treatment seeking behaviour from 83.3% to 100% before- and after the HMM implementation respectivly. Conclusion The evaluation of the project identified the feasibility of the planned model in Sudan's condition. Moreover, the communities as well as the volunteers found to be satisfied with and supportive to the system and the outcome. The problem of treating other febrile cases when diagnosis is not malaria and other non-fever cases needs to be addressed as well.
