Background: Following the World Health Organization declaration of COVID-19 as a pandemic, Yemen has taken preventive and precautionary measures against COVID-19 to control its spread. This study evaluated the knowledge, attitudes, and practices (KAP) of the Yemeni public regarding COVID-19. Methods: A cross-sectional study using an online survey was conducted during the period from September 2021 to October 2021. Results: The mean total knowledge score was 9.50 ± 2.12. The majority of the participants (93.4%) were aware that to prevent infection by the COVID-19 virus, going to crowded places and gatherings should be avoided. Approximately two thirds of the participants (69.4%) believed COVID-19 is a health threat to their community. However, in terms of actual behavior, only 23.1% of the participants reported that they did not go to any crowded places during the pandemic, and only 23.8% had worn a mask in recent days. Moreover, only about half (49.9%) reported that they were following the strategies recommended by the authorities to prevent the spread of the virus. Conclusion: The findings suggest that the general public has good knowledge and positive attitudes regarding COVID-19, but that their practices are poor.

Gestational diabetes mellitus (GDM) is associated with adverse maternal and foetal consequences, along with the subsequent risk of type 2 diabetes mellitus (T2DM) and several other diseases. Due to early risk stratification in the prevention of progression of GDM, improvements in biomarker determination for GDM diagnosis will enhance the optimization of both maternal and foetal health. Spectroscopy techniques are being used in an increasing number of applications in medicine for investigating biochemical pathways and the identification of key biomarkers associated with the pathogenesis of GDM. The significance of spectroscopy promises the molecular information without the need for special stains and dyes; therefore, it speeds up and simplifies the necessary ex vivo and in vivo analysis for interventions in healthcare. All the selected studies showed that spectroscopy techniques were effective in the identification of biomarkers through specific biofluids. Existing GDM prediction and diagnosis through spectroscopy techniques presented invariable findings. Further studies are required in larger, ethnically diverse populations. This systematic review provides the up-to-date state of research on biomarkers in GDM, which were identified via various spectroscopy techniques, and a discussion of the clinical significance of these biomarkers in the prediction, diagnosis, and management of GDM.

Background: Hashimoto’s thyroiditis (HT) is a chronic autoimmune thyroiditis that causes systemic inflammation in the body, leading to hypothyroidism and an enlargement of the thyroid gland. Objectives: This study aims to reveal whether there is a relationship between Hashimoto’s thyroiditis and the platelet-count-to-lymphocyte-count ratio (PLR), which is used as a new inflammatory marker. Methods: In this retrospective study, we compared the PLR of the euthyroid HT group and the hypothyroid-thyrotoxic HT group to the controls. We also evaluated the values of thyroid-stimulating hormone (TSH), free T4 (fT4), C-reactive protein (CRP), aspartate transaminase (AST), alanine transaminase (ALT), white blood cell count, lymphocyte count, hemoglobin, hematocrit, and platelet count in each group. Results: The PLR of the subjects with Hashimoto’s thyroiditis was found to be significantly different from the control group (p < 0.001), with the rankings as follows: hypothyroid-thyrotoxic HT 177% (72–417) > euthyroid HT 137% (69–272) > control group 103% (44–243). In addition to the increased PLR values, an increase in CRP values was also observed, revealing a strong positive correlation between the PLR and CRP in the HT patients. Conclusion: In this study, we found out that the PLR was higher in the hypothyroid-thyrotoxic HT and euthyroid HT patients than in a healthy control group.

Several studies have reported on the negative implications of elevated neutrophil-to-lymphocyte ratio (NLR) and elevated platelet-to-lymphocyte ratio (PLR) levels associated with outcomes in many surgical and medical conditions, including cancer. In order to use the inflammatory markers NLR and PLR as prognostic factors in disease, a normal value in disease-free individuals must be identified first. This study aims (1) to establish mean values of various inflammatory markers using a healthy and nationally representative U.S. adult population and (2) to explore heterogeneity in the mean values by sociodemographic and behavioral risk factors to better specify cutoff points accordingly. The National Health and Nutrition Examination Survey (NHANES) of aggregated cross-sectional data collected from 2009 to 2016 was analyzed; data extracted included markers of systemic inflammation and demographic variables. We excluded participants who were under 20 years old or had a history of an inflammatory disease such as arthritis or gout. Adjusted linear regression models were used to examine the associations between demographic/behavioral characteristics and neutrophil counts, platelet counts, lymphocyte counts, as well as NLR and PLR values. The national weighted average NLR value is 2.16 and the national weighted average PLR value is 121.31. The national weighted average PLR value for non-Hispanic Whites is 123.12 (121.13–125.11), for non-Hispanic Blacks it is 119.77 (117.49–122.06), for Hispanic people it is 116.33 (114.69–117.97), and for participants of other races it is 119.84 (116.88–122.81). Non-Hispanic Blacks and Blacks have significantly lower mean NLR values (1.78, 95% CI 1.74–1.83 and 2.10, 95% CI 2.04–2.16, respectively) as compared with that of non-Hispanic Whites (2.27, 95% CI 2.22–2.30, p < 0.0001). Subjects who reported a non-smoking history had significantly lower NLR values than subjects who reported any smoking history and higher PLR values than current smokers. This study provides preliminary data for demographic and behavioral effects on markers of inflammation, i.e., NLR and PLR, that have been associated with several chronic disease outcomes, suggesting that different cutoff points should be set according to social factors.

Background: The literature reports that catering workers are exposed to various occupational health hazardsé. Objective: This study aims to assess a cohort of catering workers in relation to upper limb disorders, thus contributing to the quantification of work-related musculoskeletal disorders in this occupational sector. Methods: Here, 500 employees, of which 130 were males and 370 were females, with an overall mean age of 50.7 years and an average length of service of 24.8 years, were examined. All subjects completed a standardized questionnaire: the medical history questionnaire of diseases of the upper limbs and spine proposed in “Health surveillance of workers”, third edition, EPC. Results: The obtained data enables the following conclusions to be drawn. Musculoskeletal disorders affect a wide range of catering workers. The most affected anatomical region is the shoulder. These disorders increase with advancing age, specifically shoulder, wrist/hand disorders and daytime and nighttime paresthesias. Employment seniority in the catering sector increases the likelihood of all considered conditions. An increase in weekly workload exclusively affects the shoulder region. Conclusions: This study aims to serve as an impetus for further research that seeks to better analyze musculoskeletal problems in the catering sector.

The German Institute for Quality and Efficiency in Healthcare (IQWiG) recently published its draft report to the government about myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The IQWiG concluded that graded exercise therapy (GET) and cognitive behavioral therapy (CBT) should be recommended in the treatment for mild and moderate ME/CFS based on two CBT and two GET studies. In this article, we reviewed the evidence used by IQWiG to support their claims, because their conclusion is diametrically opposed to the conclusion by the British National Institute for Health and Care Excellence (NICE) in its recently updated ME/CFS guidelines. Our analysis shows that the trials IQWiG used in support suffered from serious flaws, which included badly designed control groups; relying on subjective primary outcomes in non-blinded studies; alliance and response shift bias, including patients in their trials who did not have the disease under investigation, selective reporting, making extensive endpoint changes and low to very low adherence of treatments. Our analysis also shows that the report itself used one CBT and one GET study that both examined a different treatment. The report also used a definition of CBT that does not reflect the way it is being used in ME/CFS or was tested in the studies. The report noted that one study used a wrong definition of post-exertional malaise (PEM), the main characteristic of the disease, according to the report. Yet, it ignored the consequence of this, that less than the required minimum percentage of patients had the disease under investigation in that study. It also ignored the absence of improvement on most of the subjective outcomes, as well as the fact that the IQWiG methods handbook states that one should use objective outcomes and not rely on subjective outcomes in non-blinded studies. The report concluded that both treatments did not lead to objective improvement in the six-minute walk test but then ignored that. The report did not analyze the other objective outcomes of the studies (step test and occupational and benefits status), which showed a null effect. Finally, the report states that the studies do not report on safety yet assumes that the treatments are safe based on a tendency towards small subjective improvements in fatigue and physical functioning, even though the adherence to the treatments was (very) low and the studies included many patients who did not have the disease under investigation and, consequently, did not suffer from exertion intolerance contrary to ME/CFS patients. At the same time, it ignored and downplayed all the evidence that both treatments are not safe, even when the evidence was produced by a British university. In conclusion, the studies used by the report do not provide any evidence that CBT and GET are safe and effective. Consequently, the report and the studies do not provide any support for the recommendation to use CBT and GET for ME/CFS or long COVID, which, in many cases, is the same or resembles ME/CFS, after an infection with SARS-CoV-2.

Nonalcoholic fatty liver disease (NAFLD) is common among Saudi patients with type 2 diabetes (T2DM). However, recommended clinical procedures to detect it are unavailable in many locations. Therefore, better and more available diagnostic biomarkers for NAFLD are needed. Various serum parameters were suggested, and algorithms that employ routine measurements in clinical practice have been developed for the prediction of fat stores in the liver in different populations. However, no such studies have been conducted on Saudis. We aimed to compare selected biochemical markers and calculated indices in T2DM patients diagnosed with NAFLD and patients without NAFLD to find the best markers associated with NAFLD. A cross-sectional study was employed to recruit 67 people with T2DM from endocrine outpatient clinics at King Abdul-Aziz University Hospital. NAFLD was detected by ultrasonography in 28 patients. Demographic information, anthropometric, and blood pressure (BP) measurements were taken. Fasting blood samples were obtained to measure glucose, glycated haemoglobin, lipid profile, liver function tests, and highly sensitive C-reactive protein. Fatty liver index, hepatic steatosis index, NAFLD-liver fat score, and triglyceride and glucose index were calculated. Following stepwise forward likelihood ratio regression with independent variables included in one model using binary logistic regression with age and waist circumference (WC) entered as covariates, elevated diastolic BP and low high-density lipoprotein- cholesterol remained significantly associated with NAFLD (p = 0.002 and 0.03, respectively). However, none of the investigated indices could be used to diagnose the disease adequately due to low specificity, even after calculating new cut-off values. Investigating novel markers and adjusting existing equations used to calculate indices to improve sensitivity and specificity in our population is needed.

Background: A recent study reported that papillary thyroid carcinoma (PTC) was associated with increased adrenergic nerve density. Meanwhile, emerging evidence suggested that tumor-innervating nerves might play a role in shaping the tumor microenvironment. We aimed to explore the potential interaction between neuronal markers and tumor microenvironmental signatures through a transcriptomic approach. Methods: mRNA sequencing was conducted using five pairs of PTC and adjacent normal tissues. The Gene Set Variation Analysis (GSVA) was performed to calculate enrichment scores of gene sets related to tumor-infiltrating immune cells and the tumor microenvironment. The potential interaction was tested using the expression levels of a series of neuronal markers and gene set enrichment scores. Results: PTC tissues were associated with increased enrichment scores of CD8 T cells, cancer-associated fibroblasts, mast cells, and checkpoint molecules. The neuronal marker for cholinergic neurons was positively correlated with CD8 T cell activation, while markers for serotonergic and dopaminergic neurons showed an inverse correlation. Conclusion: Distinct neuronal markers exerted different correlations with tumor microenvironmental signatures. Tumor-innervating nerves might play a role in the formation of the PTC microenvironment.

The definition of acute kidney injury (AKI), despite improvements in criteria, continues to be based on the level of serum creatinine and urinary output that do not specifically indicate tubular function or injury, or glomerular function or injury that is not significant enough to warrant acute hospitalization of the patient. Finding novel biomarkers of AKI has become a major focus nowadays in nephrology to overcome the further complications of end stage renal disease (ESRD). Many compounds, such as KIM 1, IL 18, NGAL, uromodulin, calprotectin, vanin 1, galactin 3, platelet-derived growth factor (PDGF), urinary Na+/H+ exchanger isoform 3 (NHE3), retinol binding protein (RBP) and Cystatin C, are released from the renal tubules and thus any alterations in tubular function can be detected by measuring these parameters in urine. Additionally, glomerular injury can be detected by measuring immunoglobulin G, nephrin, podocalyxin, podocin, transferrin, netrin-1, pyruvate kinase M2, etc. in urine. These novel biomarkers will be useful for timing the initial insult and assessing the duration of AKI. According to available research, these biomarkers could be applied to assess the onset of AKI, distinguishing between kidney injury and dysfunction, directing the management of AKI, and enhancing disease diagnosis. Therefore, we intend to present recent developments in our understanding of significant biomarkers implicated in various aspects of renal damage. Numerous biomarkers are implicated in various pathophysiological processes that follow renal injury, and can improve prognosis and risk classification.

Obesity is a chronic multifactorial disease that has become a serious health problem and is currently widespread over the world. It is, in fact, strongly associated with many other conditions, including insulin resistance, type 2 diabetes, cardiovascular and neurodegenerative diseases, the onset of different types of malignant tumors and alterations in reproductive function. According to the literature, obesity is characterized by a state of low-grade chronic inflammation, with a substantial increase in immune cells, specifically macrophage infiltrates in the adipose tissue which, in turn, secrete a succession of pro-inflammatory mediators. Furthermore, recent studies on microbiota have postulated new possible mechanisms of interaction between obesity and unbalanced nutrition with inflammation. This intestinal “superorganism” complex seems to influence not only the metabolic balance of the host but also the immune response, favoring a state of systemic inflammation and insulin resistance. This review summarizes the major evidence on the interactions between the gut microbiota, energetic metabolism and host immune system, all leading to a convergence of the fields of immunology, nutrients physiology and microbiota in the context of obesity and its possible clinical complications. Finally, possible therapeutic approaches aiming to rebalance the intestinal microbial ecosystem are evaluated to improve the alteration of inflammatory and metabolic states in obesity and related diseases.

There is growing evidence of the association of Microscopic Colitis (MC) with the use of specific medications such as proton pump inhibitors (PPIs), Selective serotonin reuptake inhibitors (SSRIs), Non-Steroidal anti-inflammatory drugs (NSAIDs), Statins and H2-receptor antagonists (H2RA). In our study, we calculated the pooled odds of MC in patients using these drugs. We performed a detailed search of major databases, including PubMed/Medline, Scopus, web of science, and Embase, to include the studies in which odds of MC were reported after using above mentioned drugs. A random-effects model was used to pool the estimates. Thirteen studies were included in our analysis consisting of 304,482 patients (34,194 cases and 270,018 controls). In eight studies, the control group consisted of a random population selected based on age, gender and same birth year, whereas 3 studies recruited patients who presented with diarrhea and underwent colonoscopy and biopsy to rule out MC. Two studies reported odds of MC for both diarrhea and random control groups. Patients taking PPIs were more likely to develop MC, AOR 2.65 (95% CI 1.81–3.50, I2 98.13%). Similarly, higher odds of association were found in patients taking SSRIs (OR 2.12, 95% CI 1.27–2.96, I2 96.46%), NSAIDs (OR 2.02, 95% CI 1.33–2.70, I2 92.70%) and Statins (OR 1.74, 95% CI 1.19–2.30, I2 96.36%). No difference in odds of developing MC was seen in patients using H2RA compared to the control group (OR 2.70, 95% CI 0.32–5.08, I2 98.67%). We performed a subgroup analysis based on the control group and found higher odds of MC in patients on PPIs compared to the random control group (OR 4.55, 95% CI 2.90–6.19, I2 98.13%). Similarly, higher odds of MC were noted for SSRI (OR 3.23, 95% CI 1.54–4.92, I2 98.31%), NSAIDs (OR 3.27, 95% CI 2.06–4.48, I2 95.38%), and Statins (OR 2.23, 95% CI 1.41–3.06, I2 98.11%) compared to the random control group. Contrary lower odds of MC were seen in the PPI and H2RA group compared to the diarrhea control group (OR 0.68, 95% CI 0.48–0.88, I2 7.26%), (OR 0.46, 95% CI 0.14–0.78, I2 0%) respectively. We found no difference in odds of MC in patients on SSRIs (OR 0.96, 95% CI 0.49–1.42, I2 37.89%), NSAIDs (OR 1.13, 95% CI 0.49–1.76, I2 59.37%) Statins (OR 0.91, 95% 0.66–1.17, I2 0%) and H2RA (OR 3.48, 95% CI −0.41–7.36, I2 98.89%) compared to the diarrhea control group. We also analyzed the association use of PPIs and NSAIDs with the development of collagenous colitis (CC) and lymphocytic colitis. Only the use of NSAIDs was associated with increased odds of developing collagenous colitis (OR 1.61, 95% CI 1.50–1.72, I2 0%). No increased odds of CC and LC were seen in PPI users. PPIs, NSAIDs, SSRIs, and Statins are associated with an increased risk of MC compared to the random control group. On the contrary, the use of PPIs, NSAIDs, SSRIs, and Statins is not associated with an increased risk of MC when compared to the diarrhea control group.

Background: The normal tissue structure of the respiratory system is necessary to provide adequate protection of the airways and lungs. Prolonged exposure to trigger factors can result in adaptive mechanism activation and lead to the development of chronic pulmonary diseases or even dysplastic changes. Materials and methods: Respiratory system material with a pseudostratified ciliated epithelium was obtained from 12 patients (aged 16 to 95), and material with a stratified squamosa epithelium was obtained from six patients (aged 23 to 93). Routine staining was performed, and an immunohistochemistry was conducted for MUC-2, MUC-6, NAPE-PLD, IL-6 and IL-13. Results: Inflammatory processes were not detected in any of the specimens. A number of correlations were identified, with the most important being a strong positive correlation for IL-13 between the alveolar epithelium and alveolar macrophages and a strong positive correlation for IL-6 between the alveolar epithelium and alveolar macrophages in the stratified squamous epithelium group. We also detected a statistically significant difference in IL-6 in alveolar macrophages. Conclusions: There were no signs of dysplastic changes in either group. Increased secretion of IL-13 in the stratified squamous epithelium group shows its involvement in metaplastic changes in the bronchial epithelium. The secretion of atypical factors by hyaline cartilage demonstrates its plasticity and adaptability.

In many host–parasite systems, overdispersion in the distribution of macroparasites leads to parasite aggregation in the host population. This overdispersed distribution is often characterized by the negative binomial or by the power law. The aggregation is shown by a clustering of parasites in certain hosts, while other hosts have few or none. Here, I present a theory behind the overdispersion in complex spatiotemporal systems as well as a computational analysis for tracking the behavior of transmissible diseases with this kind of dynamics. I present a framework where heterogeneity and complexity in host–parasite systems are related to aggregation. I discuss the problem of focusing only on the average parasite burden without observing the risk posed by the associated variance; the consequences of under- or overestimation of disease transmission in a heterogenous system and environment; the advantage of including the network of social interaction in epidemiological modeling; and the implication of overdispersion in the management of health systems during outbreaks.

Upper gastrointestinal (GI) malignancy is a leading cause of cancer-related morbidity and mortality. Upper endoscopy has an established role in diagnosing and staging upper GI cancers, screening for pre-malignant lesions, and providing palliation in cases of advanced malignancy. New advances in endoscopic techniques and technology have improved diagnostic accuracy and increased the therapeutic potential of upper endoscopy. We aim to describe the different types of endoscopic technology used in cancer diagnosis, summarize the current guidelines for endoscopic diagnosis and treatment of malignant and pre-malignant lesions, and explore new potential roles for endoscopy in cancer therapy.

Background: With the advent of the COVID-19 pandemic caused by SARS-CoV-2, protocols such as social distancing and upscaling of hygiene practices were implemented to limit the spread of the disease. Meanwhile, along with COVID-19 came stress due to restrictions on movement, trade and transport, and closure of schools, among others. Aim: This study compared the prevalence of hygiene-related gastrointestinal infections and stress-related diseases before (March 2019–February 2020) and during (March 2020–February 2021) the COVID-19 pandemic. Methodology: This was a retrospective single-center review of deidentified patient data from the Korle Bu Polyclinic, Accra, Ghana. Results: Comparing the pre-COVID-19 era to the COVID-19 era, there was a statistically nonsignificant change in the number of cases and prevalence of gastroenteritis and enteric fever (p = 0.084 and 0.081, respectively), although for gastroenteritis, the prevalence was higher for the pre-COVID-19 era compared to during COVID-19 by 1.8 per 1000 cases, while that of enteric fever was higher during the COVID-19 era compared to the pre-COVID-19 era by 1.0 per 1000 cases. Of the stress-related diseases, statistically significant increases in the prevalence of anxiety disorders (p = 0.028), insomnia (p = 0.001), and headache (p = 0.010), were noted, with 2.3, 5.5, and 2.4 per 1000 cases, respectively. There were more female cases than male cases recorded for depression (p = 0.001), headache (p = 0.010), and hypertension (p = 0.001) during the pandemic, and these were statistically significant. Conclusion: During the pandemic, a significant increase in the prevalence of stress-related diseases was observed. However, a statistically nonsignificant change was recorded for gastrointestinal infections, with females reporting more of these disorders. Consequently, it is important to strengthen the capacity for managing stress-related conditions alongside diseases that cause pandemics when they arise.

Various mind–body fitness modalities such as Pilates, yoga, Tai Chi, and Qigong have become an accepted part of the physical activity, exercise, and leisure sector, serving several populations eligible for meditative movement activities. However, no robust evidence is present in the current literature supporting the efficacy of these meditative movement activities on health, fitness, and well-being markers among obese adults. Interestingly, the feasibility and safety of mind–body fitness programs in this cohort are still questionable. However, the limited available data show the beneficial role of such alternative exercise options in improving numerous physical fitness and cardiometabolic health-related indicators. The major role of mind–body fitness in obese individuals is to promote muscle control, body functionality, flexibility, and balance while reducing physical limitations, chronic pain, and stress through sessions integrating body postures, efficient breathing patterns, meditation, and relaxation. Such a bodily movement-based approach may be associated with increased physical performance and improved cardiometabolic as well as mental health. However, data on anthropometric characteristics, body composition and cardiovascular disease risk factors modification are somewhat equivocal. Future studies are needed to investigate a wider spectrum of physical fitness and cardiometabolic health parameters, since obese people are likely to demonstrate poor functional capacity, impaired glucose control, lipid disorder, and abnormal blood pressure levels.

Introduction: Anastomotic leakage (AL) following oesophageal surgery is the most feared complication. Therefore, it is of utmost importance to diagnose it in a timely and safe manner. The diagnostic algorithm, however, differs across institutions world-wide, with no clear consensus or guidelines. The aim of this study was to analyse whether computed tomography (CT) or upper endoscopy (UE) should be performed first. Material and Methods: Records of 185 patients undergoing oesophageal surgery for underlying malignancy were analysed. All patients that developed an AL were further analysed. Results of CT and UE were compared to calculate sensitivity. Results: Overall, 33 out of 185 patients were diagnosed with an AL after oesophagectomy. All patients received a CT and a UE. The CT identified 23 out of 33 patients correctly. Sensitivity was 69.7% for CT, compared to 100% for UE. Conclusion: If patients are clinically suspicious regarding development of an AL after oesophagectomy, UE should be performed prior to CT as it has a sensitivity of 100%. In addition, treatment by means of endoluminal vacuum therapy (EVT) or self-expanding-metal stents (SEMS) can be initiated promptly.

The right to health was enshrined in the constitution of the World Health Organization in 1946 and in the Universal Declaration of Human Rights in 1948, which also guaranteed women’s fundamental freedoms and dignity. The Declaration of Human Rights was signed by almost every country in the world. Nonetheless, gender inequalities in health and health systems continue to persist, especially in lower and middle income countries that are disproportionately affected by a litany of neglected diseases. In this paper, we focus on one of the most neglected human rights, development, and reproductive health issues globally, female genital schistosomiasis (FGS), which imposes enormous unacknowledged suffering on an estimated 56 million women and girls in Sub-Saharan Africa. Despite increasing calls for attention to FGS, no country has fully incorporated it into its health system. An appropriate response will require a comprehensive approach, guided by human rights mandates and the redress of FGS-related gender inequalities. In this paper, we propose the application of existing human rights and its clients, women, and girls affected by FGS as rights holders. Within the different components or building blocks of the health system, we propose elements of an appropriate health system response using the four components identified within the FGS Accelerated Scale Together (FAST) Package—awareness raising, prevention of infection, training of health personnel, and diagnosis and treatment. The framework is aspirational, its recommended elements and actions are not exhaustive, and countries will need to adapt it to their own situations and resource availability. However, it can be a useful guide to help health systems define how to begin to incorporate FGS into their programming in a way that responds to their human rights obligations in a gender- and culturally sensitive manner.

Background: Diabetes mellitus has some damaging effects on the genitourinary system and has been found to have adverse effects on the host immune system, resulting in higher risk of infections including urinary tract infections (UTI). Incidences of UTI caused by bacteria have been increasingly reported globally and the abuse of antibiotics leading to evolving resistant strains of antibiotics is a public health challenge for the management of this condition. Information on the difference in types of bacterial agents causing UTI in diabetic patients and non-diabetic individuals, and their susceptibility profiles, will facilitate effective management among these groups of patients. Therefore, this study aimed at determining the difference in prevalence of UTI, the causative bacteria, and their antimicrobial susceptibility profiles in diabetic patients and non-diabetic individuals at a diabetes management center. Methods: This was a prospective cross-sectional study conducted amongst 100 diagnosed diabetic patients and 100 non-diabetic individuals. Urine sample was collected aseptically and analyzed microbiologically for the presence of urinary tract bacterial pathogens. Drug susceptibility testing was conducted on the isolates by the Kirby Bauer method to ascertain the antibiotic susceptibility patterns. Results: Among the diabetic and non-diabetic individuals, urinary tract bacterial pathogens were observed in 28.0% and 26.0% of samples, respectively. The organisms were in the following proportions for diabetic and non-diabetic individuals, respectively: E. coli (14/28, 50% and 8/26, 30.7%), S. aureus (2/28, 7.1% and 4/26, 15.4%), K. pneumoniae (4/28, 14.3% and 8/26, 30.7%), K. ozoenae (2/28, 7.14% and 0/26, 0%), K. oxytoca (0/28, 0% and 4/26, 15.4%) and C. urealyticum (6/28, 21.4% and 2/26, 7.69%). The difference between the proportions of bacteria isolated was, however, not statistically significant (p-value = 0.894). Bacteria isolated from both diabetic and non-diabetic individuals were highly susceptible to most of the antibiotics tested, especially nitrofurantoin, cefuroxime, ceftriaxone, and cefotaxime. Conclusion: This study has shown that similarities exist in prevalence of UTI, the causative bacteria, and their antimicrobial susceptibility patterns amongst diabetic patients and non-diabetic individuals at a diabetes management center. These data will help in the management of UTI among these individuals.
