Biochemical markers of nephrotic syndrome: An observational, cross-sectional study.

Background: Blood protein leakage, especially albumin, into the urine is the hallmark of nephrotic syndrome (NS), which poses a serious public health problem. The absence of albumin prompts the liver to produce more proteins to make up the difference. The therapeutic significance of these additional proteins in NS is not yet fully understood. Methods: In total, 99 patients with NS and 47 persons without NS (control group) were included in this cross-sectional study. Socio-demographic and clinical information were obtained from recruits utilizing a standard questionnaire and a check of the lab order forms for individuals. Each participant had a 6-mL (6 mL) sample of venous blood taken and levels of calcium, C-reactive protein (CRP), albumin, and other proteins in the serum were assayed. The proteins in serum were separated using the electrophoresis technique, and the various fractions were then measured by a densitometer. Calculations were made for the oncotic pressure. Results: The NS group had significantly greater levels of serum CRP, urea, alpha-2-globulin, gamma globulins, and M component than the control group (p < 0.05 respectively). Transferrin, total proteins, albumin, beta-1-globulins, calcium, and oncotic pressure were significantly higher in persons without NS compared to the NS group (p < 0.05 respectively). In addition, levels of CRP (odds ratio = 1.41, p = 0.005) and gamma globulin (odds ratio = 4.12, p = 0.005) in the blood were observed to be independent predictors in the occurrence of NS. These two factors increased the likelihood of developing NS by approximately 1.5 and 4 times, respectively. Conclusion: Among the proteins assayed, CRP and gamma globulin were found to be predictors of NS. Nonetheless, further studies are required to understand the mechanisms associated with these serum proteins in NS.

Effect of circulating ceramides on adiposity and insulin resistance in patients with type 2 diabetes: An observational cross-sectional study.

INTRODUCTION: Insulin resistance (IR) is one of the common chronic metabolic disorders in Africa and elsewhere. Accumulation of lipids in the body may be due to an imbalance in the metabolism of lipids, glucose and proteins. Ceramides are a sphingolipid class of lipids that are biologically active and vital in the production of more complex lipids. Circulating ceramides are thought to have a role in the development of obesity-related IR, although the precise involvement remains unclear. AIM: To investigate the impact of circulating ceramide on IR and body adiposity in people with and without type 2 diabetes mellitus (T2DM). METHODOLOGY: The study was observational and cross-sectional. There were a total of 84 volunteers with T2DM and 75 nondiabetics (control). The participants' ages, body mass indexes (BMI), waist circumferences, and blood pressure (BP) were among the clinical parameters assessed. Ceramide levels, fasting plasma glucose (FPG), lipids, basal insulin levels and glycated haemoglobin (HbA1c) were also measured. Additionally, the homeostatic model assessment for IR (HOMA-IR) and beta cell function (HOMA-ß) were computed. RESULTS: T2DM and control participants had different mean values for anthropometric parameters, BP, FPG, HbA1c, lipids, insulin, HOMA-IR, HOMA-ß and ceramide levels (p < .05 for all). HOMA-IR, HOMA-ß and cardiovascular risk were significant correlates with ceramide levels in the T2DM group (r = 0.24; -0.34; 0.24, p < .05, respectively). Further, FPG (OR = 1.83, p = .01) and ceramide (OR = 1.05, p = .01) levels were significant predictors of IR in the case group. CONCLUSION: Patients with T2DM exhibited high ceramide concentrations, which, when combined with high FPG, were associated with IR. The consequences of circulating ceramides in health and disease; however, merit further research.

Serum leptin levels in patients with chronic kidney disease and hypertensive heart disease: An observational cross-sectional study.

Background and Aim: Adipocytes secrete a peptide hormone called leptin, which plays a crucial role in controlling appetite and energy expenditure. Alterations in leptin concentrations are associated with CKD-related cardiovascular problems such as hypertensive heart disease (HHD). Despite the link, data on the precise function of leptin in people with CKD and HHD is scant. Methods: An observational cross-sectional study involving a total of 108 participants (72 CKD patients with HHD and 36 healthy controls). Their demographic and anthropometric information was collected using a standardized questionnaire. Certain clinical measures such as blood pressure and body mass index (BMI) were assessed. Fasting blood samples were analyzed for levels of plasma glucose (FPG), lipids, creatinine, and leptin. Data were analyzed with SPSS v23. Results: Leptin, FPG, creatinine and triglyceride levels were all significantly higher in CKD patients with HHD compared to controls (p < 0.01 for all). Furthermore, advanced CKD status (being in stage 5), having a 6-year diagnosis of HHD, being female, having a higher BMI, and elevation in levels of HDL and FPG contributed significantly to the variance in serum leptin levels in the case group (ß = 0.37, 0.22, 0.19, 0.18, 0.27, 0.28; p < 0.05 for all). In the control group, the female gender had the biggest unique effect on circulating leptin levels, followed by BMI and eGFR (ß = 0.71, 0.34, -0.22; p < 0.01 for all). Conclusion: Patients with CKD who also had HHD reported considerably higher circulating leptin levels. Significantly higher blood leptin levels were shown to be associated with CKD stage 5 in the case group. These results are consistent with the role of leptin in the metabolic complexity seen in CKD patients. There needs to be more research into treatments that aim to lower leptin levels in CKD patients with HHD.

Impact of blood perilipin A levels on obesity and metabolic health.

OBJECTIVE: Perilipin A is a common protein that coats lipid surfaces preventing them from being exposed to oxidative damage. Researchers have found little consistency in the relationship between perilipin A levels in the blood and body fat. This study was a cross-sectional observational that looked at circulating perilipin A levels and how they relate to metabolic health. RESULTS: The participants in this study were 86 individuals with a mean age of 45.5 ± 1.2 years. Multiple clinical and metabolic indicators (age, weight, BMI, total body fat mass, triglyceride, and HOMA-IR) were shown to be inversely associated with perilipin A levels (rho = - 0.32, - 0.37, - 0.40, - 0.45, - 0.33 and - 0.29; p < 0.05 respectively). Obese persons were almost six times more likely than non-obese individuals to have lower perilipin A levels (odds ratio = 6.22, CI = 2.35-11.50, p < 0.001). Our findings underscore the important role of perilipin A proteins in metabolic health.

Clinical and laboratory profile and outcomes of hospitalized COVID-19 patients with type 2 diabetes mellitus in Ghana - A single-center study.

BACKGROUND: In sub-Saharan Africa and particularly in Ghana, there is scarcity of published literature specifically on the impact of DM on outcomes in COVID-19 patients. Based on the difference in genetic makeup and demographic patterns in Africans compared to the Western world and with the rising burden of DM and other non-communicable diseases in Ghana there is a need to define the impact DM has on persons with COVID-19. This would ensure adequate risk stratification and surveillance for such patients as well as appropriate scale up of therapeutic management if needed. AIMS: This single-center study describes the clinical and laboratory profile and outcomes of COVID-19 in-patients with type 2 diabetes mellitus (DM) in Ghana. MATERIALS AND METHODS: Retrospective analysis was undertaken of the medical records of adults with COVID-19 hospitalized at a facility in Ghana from March to October 2020. Clinical, laboratory and radiological data and outcomes were analysed. Comparisons between COVID-19 patients with DM and non-diabetics were done with an independent t-test or a Mann-Whitney test when normality was not attained. Odds ratios (95% CI) were calculated using univariate logistic regression. RESULTS: Out of 175 COVID-19 patients, 64 (36.6%) had DM. Overall mean age was 55.9 ± 18.3 years; DM patients were older compared to non-diabetics (61.1 ± 12.8 vs. 53.0 ± 20.2 years, p = .049). Compared to non-diabetics, diabetics were more likely to have higher blood glucose at presentation, have hypertension, be on angiotensin 2 receptor blockers [OR, 95% CI 3.3 (1.6-6.7)] and angiotensin converting enzyme inhibitors [OR, 95% CI 3.1 (1.3-7.4)]; and be HIV negative (p < .05). Although the values were normal, diabetics had a higher platelet count but decreased lymphocytes, aspartate transaminase and alkaline phosphatase compared to non-diabetics (p < .05). There was no difference in clinical symptoms, severity or mortality between the two groups. DISCUSSION: The clinical profile of patients studied are similar to prior studies. However the outcome of this study showed that DM was not associated with worse clinical severity and in-hospital mortality. This could have been due to majority of DM patients in this study having relatively good blood glucose control on admission. Secondly, DM alone may not be a risk factor for mortality. Rather its concurrent existence with multiple co-morbidities (especially cardiovascular co-morbidities which may predispose to pro-inflammatory and pro-thrombotic states) may be driving the rise in severity and mortality risks reported in other studies. Furthermore, this study was conducted among an African population and Africa has been shown to be generally less severely hit by the COVID-19 pandemic compared to other regions outside the continent. This has been postulated to be due, among other factors, to inherent protective mechanisms in Africans due to early and repeated exposure to parasitic and other organisms resulting in a robust innate immunity. CONCLUSIONS: This study suggested that DM was not associated with more severe clinical symptoms or worse outcomes among hospitalized COVID-19 patients. Despite this, it is important that DM patients adhere to their therapy, observe the COVID-19 containment protocols and are prioritized in the administration of the COVID-19 vaccines. STUDY HIGHLIGHTS: In this retrospective, single-centre study on the clinical and laboratory profile and outcome of hospitalized DM patients with COVID-19, patients with DM did not have a more severe clinical profile or worse outcomes. They were, however, significantly older, more likely to have higher admission blood glucose, have hypertension, be on angiotensin 2 receptor blockers and angiotensin converting enzyme inhibitors; and be HIV negative compared to the cohort without DM. DM patients should be a priority group for the COVID-19 vaccines.

Prevalence of Hypertension in Ghana: Analysis of an Awareness and Screening Campaign in 2019.

Introduction: Hypertension is an important public health menace globally and in sub-Saharan Africa. The prevalence of hypertension is on the rise in low- and lower-middle-income countries (LMIC) such as Ghana. This rise led to the adoption of the May Measurement Month (MMM) initiative, a global blood pressure screening campaign. We aimed to create awareness and present the findings of the 2019 MMM screening campaign in the Ashanti region of Ghana. Methods: Ghana was 1 of 92 countries that participated in this global community-based cross-sectional study in May 2019. Participants (⩾18 years) were recruited by opportunistic sampling. The blood pressures of participants were measured 3 times and the mean of the last 2 was used for the analysis. Summary statistics were used to describe the data. Simple and multiple logistic regression models were used to determine the predictors of hypertension. Results: We screened 3080 participants with a mean age of 39.8 ± 16.8 years. The prevalence of hypertension was 27.3% among participants. Two-thirds of the hypertensives were unaware of their condition and only 49.5% of participants with a history of hypertension on medication were controlled. Predictors of hypertension in a multiple logistic regression were increasing age (OR = 1.05 (CI 1.04-1.06), P < .001) and high body mass index (OR = 1.06 (1.02-1.10), P = .005). Conclusion: The MMM initiative is highly commendable and of huge public health importance in LMICs like Ghana. Population-based health programs such as the MMM initiative is encouraged to shape appropriate public health policies to reduce the prevalence of hypertension.

Predictors of rapid progression of estimated glomerular filtration rate among persons living with diabetes and/or hypertension in Ghana: Findings from a multicentre study.

In Ghana, the prevalence of chronic kidney disease (CKD) is 28.5% in diabetic hypertensive patients, 26.3% in hypertensives, and 16.1% in those with diabetes only. Trajectories of estimated glomerular filtration rate (eGFR) among patients with hypertension and diabetes are important for monitoring and instituting prompt interventions to prevent the development of CKD, especially in the face of limited access to renal replacement therapy. In this prospective multi-center study conducted at five hospitals in Ghana, we assessed predictors of rapid eGFR progression among adults with hypertension and/or diabetes. Serum creatinine at baseline and 18 months were taken and eGFR determined using the CKD-EPI formula. eGFR trajectory was defined as fast when the decline of GFR was ≥ 5 ml/min/1.73 m2 per year. A multivariable logistic regression model was fitted to identify predictors of the fast progression of eGFR. Total 13% of 1261 participants met the criteria for rapid decline in eGFR. The adjusted odds ratio, aOR (95%CI), of four factors adversely associated with fast progression of eGFR were: increasing age 1.20 (1.03-1.14), partial health insurance coverage for medications 1.48 (1.05-2.08), history of smoking 1.91 (1.11-3.27), angiotensin-receptor blockade use 1.55 (1.06-2.25) while metformin use was protective .56 (.35-.90). Proportion with eGFR <60 ml/min increased from 14% at baseline to 19% at month 18. Effective health insurance policies to improve medication access and avoidance of smoking are interventions that may mitigate the rising burden of CKD in individuals with diabetes mellitus and/or hypertension.

Long-term determinants of death after stroke in Ghana: Analysis by stroke types & subtypes.

BACKGROUND: Determinants of long-term mortality after stroke by mechanistic type and subtype are unknown in sub-Saharan Africa (SSA). Such data are crucial for targeting specific pathophysiologic pathways to improve stroke outcomes in the region. PURPOSE: To evaluate rates and predictors of mortality up to 8 years after stroke, by type and subtype, in Ghana. METHODS: We prospectively collected data on stroke patients presenting at a tertiary medical facility in Ghana between 2013 and 2018 who were followed up until October 31, 2021. Stroke diagnosis was confirmed using a Computerized Tomography scan; ischemic strokes were mechanistically typed using the TOAST classification while intracerebral hemorrhages were subtyped using the SMASH-U scheme. Demographic and clinical predictors of stroke mortality were evaluated using Cox proportional hazards regression modelling. RESULTS: Of 564 patients encountered during the study period, data on vital status were available for 556 (98.6%) subjects at discharge and 442 (78.4%) on follow-up. Mean age was 61.1 ±15.1 years, and 223 (53.1%) were male. Mortality rates at 1, 3, 12, 36, 60 and 96 months were 37.5%, 43.2%, 49.7%, 57.4%, 62.9%, and 73.7% respectively. Three (3) factors remained significantly associated with risk of death namely age, adjusted hazard ratios (aHR) of 1.12 (95%CI: 1.04-1.20), no formal education 1.36 (95% CI: 1.02-1.81) and modified Rankin score 1.67 (95%CI: 1.42 - 1.98) for each unit rise. For ischemic stroke the four (4) factors associated with long-term mortality were low formal education, low monthly income, having diabetes mellitus and higher functional score on admission. For intracerebral hemorrhage, the two factors were increasing age and high functional score. CONCLUSION: Stroke severity is the key predictor of long-term mortality after an index stroke in Ghana, regardless of the underlying pathophysiologic mechanism. Instituting acute stroke systems of care to facilitate timely reperfusion efforts may greatly improve long term survival outcomes after stroke in SSA.

Voluntary Counseling and Testing, Antiretroviral Therapy Access, and HIV-Related Stigma: Global Progress and Challenges.

To date, about 37 million people are living with the human immunodeficiency virus (HIV) and an estimated 680,000 people have died from acquired immune deficiency syndrome (AIDS) related illnesses globally. While all countries have been impacted by HIV, some have been significantly more impacted than others, particularly countries in sub-Saharan Africa. The purpose of this paper was to identify progress made in HIV prevention globally, particularly in the areas of voluntary counseling and testing (VCT) uptake, access to antiretroviral therapy (ART), and HIV-related stigma. With the development of ART, a cocktail of medications for the treatment of HIV, VCT uptake increased, as it became apparent that the medication would only be prescribed after an HIV diagnosis through testing. Widely considered a critical gateway to HIV prevention and treatment, VCT is being implemented in many countries, and as a result, about 38 million people living with HIV in 2018 had access to ART. Regardless of this success, major challenges still remain. We did an electronic search of 135 articles in English related to global HIV progress and challenges indexed in PubMed, ResearchGate, Google, and other search engines from 1998 to 2021. Sixty articles met the inclusion criteria for this paper. Data on trends in ART coverage were obtained from the Joint United Nations Programme on HIV/AIDS (UNAIDS) website. These data were used to show ART coverage globally in World Health Organization (WHO) regions. It was found that while global successes have been chalked in the areas of VCT uptake and ART coverage, HIV-related stigma has impeded greater success. This paper summarizes and discusses global successes and challenges in HIV prevention efforts in the past four decades with a focus on VCT, ART, and HIV-related stigma.

The Efficacy and Safety of Hemospray for the Management of Gastrointestinal Bleeding: A Systematic Review and Meta-Analysis.

GOALS/BACKGROUND: Hemospray is a new hemostatic powder recently approved for endoscopic hemostasis in gastrointestinal (GI) bleeding. Data are limited in terms of its clinical outcomes, and its role in the treatment algorithm of GI bleeds. We conducted a systematic review and meta-analysis to study the clinical performance of Hemospray in the management of GI bleeding. STUDY: We searched multiple databases from inception through March 2019 to identify studies that reported on the clinical outcomes of Hemospray in GI bleeding. The primary outcome was pooled rates of clinical success after the application of Hemospray in GI bleeding. The secondary outcomes were pooled rebleeding rates and adverse events after use of Hemospray. RESULTS: A total of 19 studies, 814 patients, of which 212 patients were treated with Hemospray as monotherapy, and 602 patients were treated with Hemospray with conventional hemostatic techniques. Overall pooled clinical success after the application of Hemospray was 92% [95% confidence interval (95% CI), 87%-96%; I2=70.4%]. Overall pooled early rebleeding rates after application of Hemospray was 20% (95% CI, 16%-26%; I2=54%). Overall pooled delayed rebleeding rates after the application of Hemospray was 23% (95% CI, 16%-31%; I2=34.9%). There was no statistical difference in clinical success (RR, 1.02; 95% CI, 0.96-1.08; P=0.34) and early rebleeding (RR, 0.89; 95% CI, 0.75-1.07; P=0.214) in studies that compared the use of Hemospray as monotherapy versus combination therapy with conventional therapy. CONCLUSIONS: Hemospray is highly effective in achieving immediate hemostasis in gastrointestinal bleeding. However, due to significantly high rebleeding rates, Hemospray is not suited for definitive long-term therapy.

SARPPIC: Exploiting COVID-19 Contact Tracing Recommendation through Social Awareness.

Globally, the current coronavirus disease 2019 (COVID-19) pandemic is resulting in high fatality rates. Consequently, the prevention of further transmission is very vital. Until vaccines are widely available, the only available infection prevention methods include the following: contact tracing, case isolation and quarantine, social (physical) distancing, and hygiene measures (washing of hands with soap and water and using alcohol-based hand sanitizers). Contact tracing, which is key in preventing the spread of COVID-19, refers to the process of finding unreported people who maybe infected by using a verified case to trace back possible infections of contacts. Consequently, the wide and fast spread of COVID-19 requires computational approaches which utilize innovative algorithms that build a memory of proximity contacts of cases that are positive. In this paper, a recommender algorithm called socially aware recommendation of people probably infected with COVID-19 (SARPPIC) is proposed. SARPPIC initially utilizes betweenness centrality in a social network to measure the number of target contact points (nodes/users) who have come into contact with an infected contact point (COVID-19 patient). Then, using contact durations and contact frequencies, tie strengths of the same contact points above are also computed. Finally, the above algorithmic computations are hybridized through profile integration to generate results for effective contact tracing recommendations of possible COVID-19-infected patients who will require testing in a healthcare facility. Benchmarking experimental results in the paper demonstrate that, using two interconnected relevant real-world datasets, SARPPIC outperforms other relevant methods in terms of suitable evaluation metrics such as precision, recall, and F-measure.

NTCP gene polymorphisms and hepatitis B virus infection status in a Ghanaian population.

BACKGROUND: SLC10A1 gene codes NTCP, a receptor through which the hepatitis B virus (HBV) gets access into hepatocytes - a stage of the viral cycle necessary for replication. Polymorphism variants of SLC10A1 play roles in HBV infection, viral clearance, treatment outcome, and complications, in diverse ethnic groups and countries. However, no such study has been conducted in the Ghanaian population, a country with HBV endemicity. Therefore, an exploratory study was conducted to investigate the presence of three (3) single nucleotide polymorphisms (SNPs) in the SLC10A1 gene (rs2296651, rs61745930, and rs4646287) and assessed the risk of HBV infection among the Ghanaian population. METHOD: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to determine the presence of the SNPs among 292 participants comprising 146 HBV infected persons as case-subjects and 146 HBV non-infected persons as control-subjects. RESULTS: The minor allele frequency (T) of rs2296651 was present in a significantly high proportion of cases compared with the control group (11.6% vs. 3.1%, p < 0.0001). The homozygote recessive variant of rs61745930 was present in 2.7% of the control group and 5.5% of the case group. Moreover, the minor allele frequencies of rs4646287 were 9.3 and 8.2% among the control and the case group, respectively (p = 0.767). Under the dominant (CC) genetic model of inheritance, rs2296651 was found to be protective of HBV infection [OR = 0.18 (0.07-0.44)], whereas under the co-dominant and additive model, rs2296651 was a potential risk factor for HBV infection [OR = 5.2 (95%CI: 2.1-12.8); 3.5 (95%CI: 1.6-7.6], respectively. Variants of rs61745930 and rs4646287 were not associated with HBV infection (p > 0.05). Polymorphisms in SLC10A1, however, did not show any significant association with HBV infectivity (p > 0.05). CONCLUSION: The study highlights some polymorphism proof that variants rs2296651, rs61745930, and rs4646287 exist in HBV-infected individuals in Ghana. Although variant rs2296651 was found to be associated with HBV infection, this association warrants more studies. Polymorphisms in SLC10A1 were not associated with HBV infectivity among the Ghanaian population. Further investigation is warranted to assess the offensive role of the relationship between rs2296651 and HBV infectivity.

Clostridioides difficile infection in US hospitals: a national inpatient sample study.

BACKGROUND: Hypervirulent strains of Clostridioides difficile have altered the landscape of hospital and community outbreaks. We aim to examine and compare spatiotemporal trends, incidence, hospital teaching status, mortality, and cost associated with hospital-acquired Clostridioides difficile infection (HCDI) and community-acquired Clostridioides difficile infection (CCDI). METHODS: Retrospective cohorts were studied using data from the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) from 2006 to 2015. RESULTS: A total of 76,124 cases of HCDI and 190,641 cases of CCDI were identified within the study period. The incidence of HCDI decreased from 8555 in 2006 to 7191 in 2015. Mortality also decreased during the same period (5.9% in 2006 to 1.4% 2015, p < 0.0001). Conversely, CCDI cases increased from 13,823 in 2006 to 20,637 in 2015. CCDI mortality decreased during the same period (4.3% in 2006 to 1.9% 2015, p < 0.0001). Rural hospital centers experienced the sharpest decline in HCDI mortality compared to urban and urban teaching centers (3.8%, p < 0.0001 vs 2.8%, p < 0.0001 vs 2.1%, p < 0.0001). Multivariate logistic regression indicated that increasing age (p = 0.0001), increasing hospital length of stay (p = 0.0001), and Medicare insurance (p = 0.002) were significant predictors of mortality for CDI mortality. Geospatial mapping of CCDI and HCDI revealed that the Eastern and Southern US experienced the largest incidence of CDI over 10 years. CONCLUSION: The incidence of HCDI has decreased in the past decade while the incidence of CCDI hospitalization is sharply on the rise. While hospital length of stay and mortality has decreased over time, the cost of treating CDI remains high.

Minor Papillary Relief in a Type IA Choledochal Cyst: A Case Report and Review of the Literature.

Choledochal cysts are an anatomical conundrum as they present with nonspecific symptoms generally delaying diagnosis and treatment. Its lag time remains critical, as cholangiocarcinoma, a fatal sequelae, contributes to its morbidity and mortality. Herein, we present a case of a type 1A choledochal cyst. We hope that its review on presentation, classification system, diagnosis, and management prevent complications and cataclysmic results.

Hepatobiliary strongyloidiasis presenting as an ampullary lesion on esophagogastroduodenoscopy/endoscopic ultrasound.

Strongyloidiasis is an intestinal infection caused by the parasitic nematodes of the Strongyloides species, most commonly Strongyloides stercoralis. We report a case of a 66-year-old immigrant male from Haiti who presented with complaints of diarrhea and an unintentional 80-lb weight loss over the past 5 years. Stool examination was positive for strongyloidiasis. Following albendazole therapy, esophagogastroduodenoscopy (EGD) showed a unique ampullary lesion. Histopathology of the ampullary lesion showed reactive epithelium with Strongyloides larva. In addition, endoscopic ultrasound (EUS) detected a large pancreatic cyst. Both these findings were absent on EGD 5 years previously, prior to the onset of his symptoms. This paper documents a rare case of an ampullary lesion and pancreatic cyst secondary to hepatobiliary strongyloidiasis in a non-Human Immunodeficiency Virus (HIV) patient. We review the epidemiology, life cycle, clinical presentation and treatment of strongyloidiasis.

Evaluation and Management of Premalignant Conditions of the Esophagus: A Systematic Survey of International Guidelines.

Esophageal cancer represents one of the most lethal forms of malignancy. The growing incidence of esophageal adenocarcinoma represents an emerging public health concern. This review article summarizes current diagnostic, management, and therapeutic practices of premalignant conditions of the esophagus including Barrett's esophagus, tylosis, granular cell tumors, achalasia, and the ingestion of caustic substances. Our report provides clinicians and academics with a global clinical perspective regarding presentation, surveillance guidelines, and therapeutic management of these esophageal conditions.

Practice measures for controlling and preventing hospital associated Clostridium difficile infections.

Clostridium difficile (CD) is the most common cause of nosocomial diarrhea. We aim to highlight practice measures for controlling and preventing Clostridium difficile infections (CDI) in the hospital setting. Electronic databases including PubMed, MEDLINE, Google Scholar, ClinicalTrials.gov, and Cochrane Databases were searched for human studies that assessed strategic measures for the prevention of CDI. Bundled interventions can effectively reduce the rates of CDI. Current evidence support the implementation antibiotic stewardship programs, hygiene enhancement, dietary management with probiotics, use of copper surfaces, and the cautious use of PPIs. However, current guidelines do not advocate the use of copper, probiotics, or the discontinuation of PPIs as a means for reducing CDI. We review these practical and evidence-based approaches.

Clinical characteristics of males with systemic lupus erythematosus (SLE) in an inception cohort of patients in Ghana.

BACKGROUND: Systemic Lupus Erythematosus (SLE) is said to be rare in Sub-Saharan Africa and even rarer in males worldwide. SLE is mostly considered a disease of women, though men may also be affected, and this may lead to a delay in diagnosis in men. The result is a greater burden of inflammation and subsequent organ damage over time. METHOD: Data from the medical records of 13 male patients diagnosed with SLE at the Rheumatology Clinic of Korle- Bu Teaching Hospital between January 2014 and January 2017 was retrospectively analyzed. RESULTS: A total of 13 male patients out of a total of 134 SLE patients were included in our analysis. The mean age was 30.62 ± SD 8.47 years (range of 17 to 46 years). All of them (100%) presented with constitutional features. The most common ACR criteria observed was 61.5 % rash, 54.5 % oral ulcers, 92.3% arthritis, 61.5 % serositis and 38.5% renal involvement, 46.2 % CNS involvement. Looking at their serological profile, 91.7 % had a positive antinuclear antibody (ANA). 33.3 % had positive anti-dsDNA and 58.3 % extractable nuclear antigens. The mean duration from onset of symptoms to diagnosis was 21.31 months. Five patients were diagnosed with lupus nephritis, all at the time of diagnosis. There were no mortalities. CONCLUSION: Male SLE patients in Ghana are comparable to other populations, with arthritis and constitutional features being predominant early features and lupus nephritis being the main early indicator of organ damage. This should warrant aggressive management in male patients. FUNDING: None declared.
