Sexual function among older men is often thought to decrease as part of normal ageing biology despite the fact that sexuality remains an important issue in the elderly. Sexual dysfunction in the aged male is likely multifactorial in nature, with the development and/or progression of medical comorbidities often resulting in decline in male sexual function and poor treatment response. At present, sexual dysfunction in the ageing male is poorly investigated and understood, and current treatment strategies aim at improving sexual desire and erectile function with limited data on ejaculatory and orgasmic dysfunctions. In addition, men are often reticent to seek help for health concerns including sexual dysfunction. The following article provides a narrative review of strategies to address various aspects of sexual dysfunction in the ageing male. Clinicians need to be educated to be sensitive when discussing sexuality issues among older men and to present practical solutions that take into account individual and cultural differences.

Abstract Background : Pneumonia remains the leading cause of death in children under five worldwide, accounting for about 1.6 million deaths a year. Streptococcus pneumonia , has proved to be the most competent bacterial pathogen causing pneumonia infections among the infants and the elderly, leading to great morbidity and mortality. Currently there are over 94 different serotypes of Streptococcus pneumonia , and quite a number have emerged as drug-resistant strains which introduce a twist to the current treatment strategies. Detailed information of current antibiotic susceptibilities, resistance and serotype distribution will be important in designing new strategies for treatment and management of pneumococcal infections. Methods: A total of 309 S. pneumoniae isolates were collected from patients attending the Kisii Teaching and Referral Hospital between 2017 and 2018. Nasopharyngeal samples collected and serotyped using PCR. The samples were cultured and their sensitivity to drugs tested using various concentrations of; Oxacilin, Erythromycin, Tetracycline, Ofloxacin, Trimethoprim/sulfamethoxazole and Chloramphenicol. Results: Out of the 309 samples collected, 235 were positive for S. pneumonia, although 10 of the samples had incomplete data. A total of 41 S. pneumonia serotypes isolated from the 309 samples with the most prevalent serotypes being; Non-typable (11%), 15B (7.6%), 19F (7.0%), 19A (6.7%), 23B (5.8%), 23F (5.3%), 6A (4.4%). All the serotypes were highly resistant to Oxacilin, and trimethoprim/sulfamethoxazole, while showing high sensitivity to Erythromycin, Ofloxacin and chloramphenicol. The rate of sensitivity to Tetracycline was 75% with the other 25% showing intermediate sensitivity. Conclusions: The data collected showed a high rate of S. pneumonia (76%) consisting of various serotypes for various ages. The various serotypes isolated showed a marked resistance routinely used antibiotics for patient samples of various ages. The isolated serotypes also consisted of serotypes 19A, 6A, and 5B that are lacking in the pneumococcal vaccine (PCV 10). This data will provide relevant information for a better approach to both clinical treatment, management and prevention of infections with S. pneumonia.

Background: The incidence of pancreatic cancer (PC) is rising in parallel with the deaths caused by this malignant disease largely due to limited improvement in current treatment strategies. In spite of aggressive PC research, for the past three decades, there has been no significant improvement in the five-year survival for this cancer. Like many other cancers, it takes several years for normal pancreatic cells to transform into pancreatic precursor lesions and to further progress into invasive carcinoma. Hence there is a scope for the development of chemo-preventive strategies to inhibit/ delay/prevent progression of this disease into an advanced stage cancer. Objective: Chemoprevention of pancreatic cancer. Method: Review of published literature. OResults and Conclusion: Availability of various genetically engineered mouse (GEM) models of PC has led to accelerated progress in understanding the disease and developing intervention strategies otherwise stalled for a long time. These GEM models spontaneously develop PC in a stepwise manner and mimic the disease etiology in humans. Understanding PC development from initiation to progression to metastasis is very important for early detection and prevention of PC. In this review, we focus on the current situation, the potential challenges, the progress in existing strategies and available opportunities as well as suggest key areas for research within the increasingly important area of pancreatic cancer chemoprevention.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor type with low patient survival due to the low efficacy of current treatment options. Cancer-associated fibroblasts (CAFs) in the tumor microenvironment (TME) create a dense fibrotic environment around the tumor cells, preventing therapies from reaching their target. Novel 3D in vitro models are needed that mimic this fibrotic barrier for the development of therapies in a biologically relevant environment. Here, novel PDAC microtissues (µtissues) consisting of pancreatic cancer cell core surrounded by a CAF-laden collagen gel are presented, that is based on the cells own contractility to form a hard-to-penetrate barrier. The contraction of CAFs is demonstrated facilitating the embedding of tumor cells in the center of the µtissue as observed in patients. The µtissues displayed a PDAC-relevant gene expression by comparing their gene profile with transcriptomic patient data. Furthermore, the CAF-dependent proliferation of cancer cells is presented, as well as the suitability of the µtissues to serve as a platform for the screening of CAF-modulating therapies in combination with other (nano)therapies. It is envisioned that these PDAC µtissues can serve as a high-throughput platform for studying cellular interactions in PDAC and for evaluating different treatment strategies in the future.

Interventional therapies using angioplasty and stenting of symptomatic stenosis of the proximal supraaortic vessels have evolved as safe and effective treatment strategies. The aim of this paper is to summarize the current treatment concepts for stenosis in the subclavian and brachiocephalic artery with regard to clinical indication, interventional technique including selection of the appropriate vascular approach and type of stent, angiographic and clinical short-term and long-term results and follow-up. The role of hybrid interventions for tandem stenoses of the carotid bifurcation and brachiocephalic artery is analysed. A systematic review of data for angioplasty and stenting of symptomatic extracranial vertebral artery stenosis is discussed with a special focus on restenosis rate.

: Fabry disease is an X-linked disorder of glycosphingolipid metabolism that results in progressive accumulation of neutral glycosphingolipids, predominantly globotriaosylsphingosine (Gb3) in lysosomes, as well as other cellular compartments of several tissues, causing multi-organ manifestations (acroparesthesias, hypohidrosis, angiokeratomas, signs and symptoms of cardiac, renal, cerebrovascular involvement). Pathogenic mutations lead to a deficiency of the lysosomal enzyme alpha-galactosidase A (GLA). In the presence of high clinical suspicion, a careful physical examination and specific laboratory tests are required. Finally, the diagnosis of Fabry’s disease is confirmed by the demonstration of the absence of or reduced alpha-galactosidase A enzyme activity in hemizygous men and gene typing in heterozygous females. Measurement of the biomarkers Gb3 and Lyso Gb3 in biological specimens may facilitate diagnosis. The current treatment of Anderson-Fabry disease is represented by enzyme replacement therapy (ERT) and oral pharmacological chaperone. Future treatments are based on new strategic approaches such as stem cell-based therapy, pharmacological approaches chaperones, mRNA therapy, and viral gene therapy. : This review outlines the current therapeutic approaches and emerging treatment strategies for Anderson-Fabry disease.

Background: Arginine is considered a semi-essential amino acid in healthy adults and the elderly. This amino acid seems to improve the immune system, stimulate cell growth and differentiation, and increase endothelial permeability, among other effects. For those reasons, it has been theorized that arginine supplementation may be used as an adjuvant to conventional cancer therapy treatments. Objective: This review aims to evaluate the existing knowledge of the scientific community on arginine supplementation in order to improve the efficacy of current cancer treatment. Results: Despite the continued efforts of science to improve treatment strategies, cancer remains one of the greatest causes of death on the planet in adults and elderly people. Chemo and radiotherapy are still the most effective treatments but at the cost of significant side effects. Conclusion: Thus, new therapeutic perspectives have been studied in recent years, to be used in addition to traditional treatments or not, seeking to treat or even cure the various types of cancer with fewer side effects.

The treatment of meniscus injuries has recently been facing a paradigm shift toward the field of tissue engineering, with the aim of regenerating damaged and diseased menisci as opposed to current treatment techniques. This review focuses on the structure and mechanics associated with the meniscus. The meniscus is defined in terms of its biological structure and composition. Biomechanics of the meniscus are discussed in detail, as an understanding of the mechanics is fundamental for the development of new meniscal treatment strategies. Key meniscal characteristics such as biological function, damage (tears), and disease are critically analyzed. The latest technologies behind meniscal repair and regeneration are assessed.
