The Prevalence of Potentially Inappropriate Medications Among Patients With Diabetic Nephropathy: A Cross-Sectional Study Conducted at a Tertiary Care Hospital.

Background Diabetic nephropathy is a serious complication of diabetes that significantly increases the risk of chronic kidney disease (CKD) and end-stage renal disease (ESRD). A critical concern in managing patients with diabetic nephropathy is the prevalence of potentially inappropriate medications (PIMs), which can exacerbate kidney dysfunction and lead to adverse health outcomes. PIMs are defined as medications whose risks outweigh their benefits, particularly when safer alternatives are available.

Challenges and Outcomes of the First Stem Cell Transplant Program in Tanzania, East Africa.

Introduction: Due to the significant resources involved in creating HSCT programs there is a significant disparity in the availability of this treatment modality between the developed and developing countries. This manuscript details the process and the outcomes of the first HSCT program in East Africa which was started at Muhimbili National Hospital (MNH) in Dar-es-Salaam, Tanzania.

Materials And Methods: Information and data were collected on the processes which had been implemented for starting the HSCT program at MNH.

Production of large, defined genome modifications in rats by targeting rat embryonic stem cells.

Rats were more frequently used than mice to model human disease before mouse embryonic stem cells (mESCs) revolutionized genetic engineering in mice. Rat ESCs (rESCs) were first reported over 10 years ago, yet they are not as frequently used as mESCs. CRISPR-based gene editing in zygotes is widely used in rats but is limited by the difficulty of inserting or replacing DNA sequences larger than about 10 kb.

Efficient engraftment and viral transduction of human hepatocytes in an FRG rat liver humanization model.

Humanized liver rodent models, in which the host liver parenchyma is repopulated by human hepatocytes, have been increasingly used for drug development and disease research. Unlike the leading humanized liver mouse model in which Fumarylacetoacetate Hydrolase (Fah), Recombination Activating Gene (Rag)-2 and Interleukin-2 Receptor Gamma (Il2rg) genes were inactivated simultaneously, generation of similar recipient rats has been challenging. Here, using Velocigene and 1-cell-embryo-targeting technologies, we generated a rat model deficient in Fah, Rag1/2 and Il2rg genes, similar to humanized liver mice.

Helicobacter pylori Infection in Africa: Update of the Current Situation and Challenges.

Background: The burden of Helicobacter pylori infection (HPI) in Africa remains high with varying levels of prevalence among children and adults reported in different regions of the continent. Persistent and uneradicated HPI could result in gastric cancer, although less severe pathological outcomes have been reported among Africans - the so-called "African enigma."

Summary: Analysis of endoscopic findings of the upper gastrointestinal tract demonstrates similarities with that of patients from the West.

Hepatitis C infection at a tertiary hospital in South Africa: Clinical presentation, non-invasive assessment of liver fibrosis, and response to therapy.

Background: Hepatitis C is a viral infection that leads to chronic liver disease, resulting in significant morbidity and mortality.

Objectives: To describe the demographic characteristics and clinical presentation of patients with chronic hepatitis C infection. The aspartate aminotransferase-to-platelet ratio index (APRI) and the fibrosis index based on 4 factors (FIB-4) were assessed for prediction of liver fibrosis.

Helicobacter pylori patient isolates from South Africa and Nigeria differ in virulence factor pathogenicity profile and associated gastric disease outcome.

Helicobacter pylori is a gram-negative, spiral-shaped bacterial pathogen and the causative agent for gastritis, peptic ulcer disease and classified as a WHO class I carcinogen. While the prevalence of H. pylori infections in Africa is among the highest in the world, the incidence of gastric cancer is comparably low.

Meralgia paresthetica: Now showing on 3T magnetic resonance neurography.

Meralgia paresthetica is a neuropathy of the lateral femoral cutaneous nerve. Traditionally, the diagnosis is based on classical symptoms and signs. In cases where there is a diagnostic dilemma, the role of magnetic resonance imaging has been to exclude other causes for the patient's presentation, as the small extraspinal peripheral nerves were not well visualised at imaging.

Detection of Helicobacter pylori and its virulence genes (cagA, dupA, and vacA) among patients with gastroduodenal diseases in Chris Hani Baragwanath Academic Hospital, South Africa.

Background: The global prevalence of H. pylori approaches 50%, with prevalence rates between 20 and 40% in developed countries and up to 90% in Africa and other developing nations of the world. Development of H.

International Consensus on Guiding Recommendations for Management of Patients with Nonsteroidal Antiinflammatory Drugs Induced Gastropathy-ICON-G.

Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs), one of the most commonly used medications worldwide, are frequently associated with gastrointestinal adverse events. Primary care physicians often face the challenge of achieving adequate pain relief with NSAIDs, while keeping their adverse events to a minimum. This is especially true when long-term use of NSAIDs is required such as in patients with osteoarthritis and rheumatoid arthritis.

Hepatitis C in sub-Saharan Africa: the current status and recommendations for achieving elimination by 2030.

In 2016, WHO adopted a strategy for the elimination of viral hepatitis by 2030. Africa, and more specifically, sub-Saharan Africa, carries a substantial portion of the global burden of viral hepatitis, especially chronic hepatitis B and hepatitis C virus infections. The task that lies ahead for sub-Saharan Africa to achieve elimination is substantial, but not insurmountable.

Hepatitis B in sub-Saharan Africa: strategies to achieve the 2030 elimination targets.

The WHO global health sector strategy on viral hepatitis, created in May, 2016, aims to achieve a 90% reduction in new cases of chronic hepatitis B and C and a 65% reduction in mortality due to hepatitis B and C by 2030. Hepatitis B virus (HBV) is endemic in sub-Saharan Africa, and despite the introduction of universal hepatitis B vaccination and effective antiviral therapy, the estimated overall seroprevalence of hepatitis B surface antigen remains high at 6·1% (95% uncertainty interval 4·6-8·5). In this Series paper, we have reviewed the literature to examine the epidemiology, burden of liver disease, and elimination strategies of hepatitis B in sub-Saharan Africa.

Focused process improvement events: sustainability of impact on process and performance in an academic radiology department.

Purpose: To evaluate sustainability of impact of rapid, focused process improvement (PI) events on process and performance within an academic radiology department.

Methods: Our department conducted PI during 2011 and 2012 in CT, MRI, ultrasound, breast imaging, and research billing. PI entailed participation by all stakeholders, facilitation by the department chair, collection of baseline data, meetings during several weeks, definition of performance metrics, creation of an improvement plan, and prompt implementation.

Insights into the development of alcoholic chronic pancreatitis at Soweto, South Africa: a controlled cross-sectional study.

Objective: We asked why so few working-class Africans of Soweto have chronic pancreatitis (CP) when alcoholism is the norm.

Methods: Twenty-one alcoholics with acute psychosis but normal pancreas were investigated for lifestyle, micronutrient status, electrophilic stress, and iron overload.

Results: Alcoholics consumed more ethanol daily than did 14 previously studied patients with CP (P = 0.

Novel 180- and 480-base-pair insertions in African and African-American strains of Helicobacter pylori.

Helicobacter pylori is a genetically diverse bacterial species that chronically infects human stomachs and sometimes causes severe gastroduodenal disease. Studies of polymorphic DNA sequences can suggest geographic origins of individual strains. Here, we describe a 180-bp insertion (ins180), which is just after the translation stop of a gene of unknown function, near the promoter of jhp0152-jhp0151 two-component signal transduction genes in strain J99, and absent from this site in strain 26695.

Detection of a putative novel Wolinella species in patients with squamous cell carcinoma of the esophagus.

Background: Certain regions of South Africa exhibit an extraordinarily high incidence of esophageal carcinoma that develops via an esophagitis-dysplasia-carcinoma sequence. Bacteria belonging to the family Helicobacteraceae are candidates for involvement in the initiation of the esophagitis. We investigated patients with esophageal carcinoma for the occurrence of Helicobacter-related species.

Agonist- and protein kinase C-induced phosphorylation have similar functional consequences for gastrin-releasing peptide receptor signaling via Gq.

Acute desensitization of many guanine nucleotide-binding protein-coupled receptors (GPCRs) requires receptor phosphorylation and subsequent binding of an arrestin. GPCRs are substrates for phosphorylation by several classes of kinases. Gastrin-releasing peptide receptor (GRPr) is phosphorylated by a kinase other than protein kinase C (PKC) after exposure to agonist and is also a substrate for PKC-dependent phosphorylation after treatment with 12-O-tetradecanoylphorbol 13-acetate (TPA).

Major differences in the IgG subclass response to Helicobacter pylori in the first and third worlds.

Background: Studies in developed countries would suggest that the immune response to Helicobacter pylori infection is a T helper cell I predominant response. Unlike subjects from developed countries, those resident in developing countries are subject to infection with a myriad of gastrointestinal pathogens from early in life. Given that H.

Gastric cancer in sub-Saharan Africa.

Gastric cancer has a variable but generally low prevalence in black populations of sub-Saharan Africa, despite a high prevalence of Helicobacter pylori (the 'African enigma'). Evidence from Soweto indicates that the host response to H. pylori may be protective against a virulent organism and that, in most people, H.

Helicobacter pylori--an African perspective.

Helicobacter pylori is ubiquitous in Africa, with acquisition in childhood the rule. Despite the prevalence of a virulent strain (in Soweto, most H. pylori organisms are cagA- and vacAS(1)-positive) H.

A randomized, double-blind, double-dummy, multicenter trial of voriconazole and fluconazole in the treatment of esophageal candidiasis in immunocompromised patients.

The efficacy, safety, and tolerability of voriconazole and fluconazole were compared in 391 immunocompromised patients with mycology- and biopsy-proven esophageal candidiasis. Primary efficacy analysis (256 patients) of esophageal treatment as assessed by esophagoscopy revealed success rates of 98.3% with voriconazole and 95.
