We aimed to establish a practical nomogram for predicting the risk incidence of prediabetes and prediabetes conversion to diabetes. METHODS: A cohort of 1428 subjects was collected to develop prediction models. The LASSO was used to screen for important risk factors in prediabetes and diabetes and was compared with other algorithms (LR, RF, SVM, LDA, NB, and Treebag). Multivariate logistic regression analysis was used to construct the prediction model of prediabetes and diabetes, and drawn the predictive nomogram. The performance of the nomograms was evaluated by receiver-operating characteristic curve and calibration. RESULTS: These findings revealed that the other six algorithms were not as good as LASSO in terms of diabetes risk prediction. The nomogram for individualized prediction of prediabetes included "Age," "FH," "Insulin_F," "hypertension," "Tgab," "HDL-C," "Proinsulin_F," and "TG" and the nomogram of prediabetes to diabetes included "Age," "FH," "Proinsulin_E," and "HDL-C". The results showed that the two models had certain discrimination, with the AUC of 0.78 and 0.70, respectively. The calibration curve of the two models also indicated good consistency. CONCLUSIONS: We established early warning models for prediabetes and diabetes, which can help identify prediabetes and diabetes high-risk populations in advance.

Therefore, this study focused on the role and associated molecular mechanism of zinc in HAART-induced sexual and erectile dysfunction. MATERIALS AND METHODS: Twenty male Wistar rats were randomly grouped into four (n = 5 rats per group); the control, zinc-treated, HAART-treated, and HAART + zinc-treated groups. Treatments were per os daily for eight weeks. RESULTS: Zinc co-administration significantly improved HAART-induced increase in the latencies of mount, intromission, and ejaculations. Zinc also attenuated HAART-induced reduction in the motivation to mate, penile reflex/erection, and frequencies of mount, intromission, and ejaculations. In addition, zinc co-treatment improved HAART-induced decline in penile NO and cGMP, dopamine, and serum testosterone. More so, zinc prevented HAART-induced rise in penile activities of monoamine oxidase, acetylcholinesterase, phosphodiesterase-5, and arginase. Furthermore, concomitant treatment with zinc ameliorated HAART-induced penile oxidative stress and inflammation. CONCLUSION: In conclusion, our present findings show that zinc improves sexual and erectile function in HAART-treated rats by upregulating erectogenic enzymes via the maintenance of penile redox balance.

MATERIALS AND METHODS: Participants aged 20-80 years from six consecutive cycles of the NHANES 2007-2018 were included in this study. According to their MetS status and BMI, the included participants were allocated into six mutually exclusive groups: metabolically healthy normal weight (MHN)/overweight (MHOW)/obesity (MHO) and metabolically unhealthy normal weight (MUN)/overweight (MUOW)/obesity (MUO). To explore the association between MetS-BMI phenotypes and the risk of kidney stones, binary logistic regression was used to determine the odds ratios (ORs). RESULTS: A total of 13,589 participants were included. It was revealed that all the phenotypes with obesity displayed higher risks of kidney stones (OR = 1.38, < 0.01 for MHO & OR = 1.80, < 0.001 for MUO, in the fully adjusted model). The risk increased significantly when metabolic dysfunction coexisted with overweight and obesity (OR = 1.39, < 0.05 for MUOW & OR = 1.80, < 0.001 for MUO, in the fully adjusted model). Of note, the ORs for the MUO and MUOW groups were higher than those for the MHO and MHOW groups, respectively. CONCLUSIONS: Obesity and unhealthy metabolic status can jointly increase the risk of kidney stones. Assessing the metabolic status of all individuals may be beneficial for preventing kidney stones.

METHOD: A comprehensive search of four electronic databases (China National Knowledge Infrastructure, PubMed, Web of Science, and Cochrane Library) was performed to identify eligible comparative studies as of April 2022. Parameters, including perioperative results and oncological and functional outcomes, were evaluated. RESULTS: Seven articles with 7575 patients undergoing RARP were included in this study. Patients with prostate cancer were grouped by age ≥ 75 years versus < 75 years. Our results demonstrated that compared with the older group, the younger group had better potency ( < .00001). However, there were no significant differences in operation time ( = .29), estimated blood loss ( = .13), length of hospital stay ( = .48), complications ( = .22), continence ( = .21), positive surgical margin ( = .28), and biochemical recurrence ( = .74) between the groups. CONCLUSION: Our study revealed that the perioperative, oncological, and functional outcomes in men aged over 75 years undergoing RARP were not significantly different from those of their younger counterparts. RARP is feasible in men aged over 75 years.

When CaP progressed to castration-resistant CaP (CRPC), the prognosis is poor. Although CaP/CRPC and BPH frequently coexist in prostate, the inter-relational mechanism between them is largely unknown. METHODS: Single-cell RNA sequencing, bulk-RNA sequencing, and microarray data of BPH, CaP in the Gene Expression Omnibus database were obtained and comprehensively analyzed. Weighted Gene Co-Expression Network Analysis (WGCNA) and lasso regression analysis were performed to explore the potential biomarkers. RESULTS: With WGCNA, five modules in BPH, two in CaP, and three in CRPC were identified as significant modules. Pathway enrichment analysis found that the epigenetics and chromosomal-related signaling were dominantly clustered in the CaP group but not in BPH and CRPC. Lasso regression analysis was used to analyze further the mutual genes between the BPH module and the CRPC module. As a result, DDA1, ERG28, OGFOD1, and OXA1L were significantly correlated with the transcriptomic features in both BPH and CRPC. More importantly, the role of the four gene signatures was validated in two independent anti-PD-1 immunotherapy cohort. CONCLUSION: This study revealed the shared gene signatures and immune microenvironment between BPH and CRPC. The identified hub genes, including DDA1, ERG28, OGFOD1, and OXA1L, might be potential therapeutic targets for facilitating immunotherapy in prostate cancer.

METHOD:...INTRODUCTION: Various approaches are required to prevent and treat heterogeneity-based prostate cancer. Here, we analyzed the anticancer effects of metformin, which has a good toxicity profile and is inexpensive. METHOD: From January 2010 to December 2019, analysis was conducted retrospectively in a cohort from the National Health Insurance Service database. The wash-out period was set for cancer diagnosis in 2010 and 2011, and subjects (105,279) diagnosed with prostate cancer (ICD C61) from 2012 to 2014 were excluded The final subjects (105,216) were defined as the metformin administration group when they took metformin for 180 days or more from January 2012 to December 2019. The non-metformin group was defined as those who took less than 180 days from January 2012 to December 2019. The prevalence of prostate cancer according to metformin administration and the risk according to the cumulative duration of metformin were analyzed. RESULTS: A total of 105,216 people were included in this study, with 59,844 in the metformin group and 45,372 in the metformin non-administration group. When calculating HRs (Hazard Rate) according to the cumulative period of metformin administration, metformin administration period length was inversely associated with prostate cancer risk (Q2 HR = 0.791 95% CI: 0.773-0.81, Q3 HR = 0.634 95% CI: 0.62-0.649, Q4 HR = 0.571 95% CI: 0.558-0.585). HRs tended to decrease with the cumulative duration of metformin administration. CONCLUSION: This study confirmed that prostate cancer risk decreased with increasing duration of metformin administration. Metformin should be considered as a new strategy in the treatment and prevention of prostate cancer characterized by heterogeneity.

Surgical and medical co-management (SMC) is a new strategy to improve patients' healthcare outcomes in surgical settings. METHODS: We reviewed the clinical data of older patients with chronic diseases who were cared for with SMC undergoing RRP in our hospital in the past 3 years and compared them with the clinical data from the general urology ward. Preoperative conditions and related indicators of recovery, and incidence of postoperative complications with the Clavien Grade System were compared between these two groups. RESULTS: The indicators of recovery were significantly better, and the incidence rates of complications were significantly reduced in the SMC group at grades I-IV ( < 0.05), as compared to the general urology ward group. CONCLUSIONS: The provision of care by SMC for older patients focused on early identification, comorbidity management, preoperative optimization, and collaborative management would significantly improve surgical outcomes. The SMC strategy is worthy of further clinical promotion in RRP treatment in older men with chronic diseases and complex medical conditions.

METHODS: This is a descriptive case report of a 54 year male with a spontaneous fracture and osteoporosis in the presence of what many consider a normal male testosterone level. RESULTS: After discovering and documenting osteoporosis by DXA scan, the patient was shown to reverse the diagnosis of osteoporosis in a year on pelleted testosterone therapy. Consistent levels of 943 ng/dL were achieved; the patient also experienced improvements in quality of life and sleep apnea. CONCLUSION: Testosterone deficiency (TD) is a clinical syndrome and osteoporosis can be found in levels above standard "criteria" of 300. This patient did not realize a benefit on injections both physical and clinically and both improved on pelleted testosterone. This should be further studied and considered for TD in men.

In this study, we aimed to investigate the relationship between the T, M category and the erector spinae muscle area (ESMa). MATERIAL AND METHODS: The initial first thorax and high-resolution computed tomography (CT) of patients with lung cancer between 2015 and 2019 were retrospectively screened. After exclusion criterias remaining 226 male patients constituted the study group. ESMa was measured manually in the section taken from the T12 vertebra spinous process level as previously described in the literature and its relationship with the T and M stage were evaluated. RESULTS: The mean ages of patients were 70 ± 9.57 years. The T stage was T1 in 34 (15%) patients, T2 in 46 (20.4%), T3 in 59 (26.1%), and T4 in 87 (38.5%). Metastasis was detected in 83 (36.7%) patients. The mean ESMa of the patients was 34.15 ± 7.21 mm and did not differ according to the T stage ( = .39). ESMa was lower in the metastatic group (mean 30.42 ± 6.38 mm) than the non-metastatic group (mean 36.32 ± 6.78 mm) ( = .0001). CONCLUSIONS: ESMa, one of the indicators of sarcopenia, is lower in patients with metastatic lung cancer than in nonmetastatic.

However, the literature on eating disorders in men is still very limited, and the actual extent is not known. Even less is known about the epidemiology of eating disorders in older individuals. In this focused review, we will present an update of the available data on disordered eating and eating disorders in middle-aged and older males. In addition, we will highlight the relationship of eating disorders with excessive sports as a purging method of choice for this age group and discuss the impact of age-related hormonal imbalances in aging men.

MATERIALS AND METHODS: This study examined the effect of daily low-dose tadalafil (5 mg) on patients' quality of life (including that of sex life) and blood circulation. Erectile dysfunction questionnaires were administered to 20 patients with type 2 diabetes (T2DM) and ED. The safety and efficacy of tadalafil were evaluated using laboratory tests, and the effect on blood circulation was measured through nail fold capillaroscopy. RESULTS: Daily tadalafil use by patients with T2DM and ED showed a statistically significant increase in the erectile reliability score from of 1.15 to 3.20 ( < .00012). Capillary blood circulation improvement tests showed a statistically significant increase in apical limb width from 13.1 to 14.64 µm ( = .04829) and flow from 9035 to 11946 μm/s ( = .04405). Although not significant, increased capillary width and speed (rate of blood flow) confirmed improved blood circulation. There were no significant changes in the cardiac indicators (troponin, prostate-specific antigen, or electrocardiogram tests) before and after tadalafil administration, supporting the safety of its low-dose daily administration. CONCLUSIONS: A small dose of daily tadalafil was shown to safely improve erectile dysfunction and peripheral blood flow in patients with T2DM, in which peripheral arterial diseases should not be considered separately but rather as complex entities.

MATERIALS AND METHODS: Medical records were obtained from a health promotion center database between 2021 and 2022. Men without a history of treatment for LUTS were evaluated using the International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), transrectal ultrasonography. RESULTS: Of 1345 individuals, 603 (44.8%) had MetS. Older age, higher IPSS values, higher prevalence rates of BPH and overactive bladder, higher triiodothyronine, and lower testosterone and sex-hormone binding globulin were observed in individuals with MetS than in individuals without MetS. The severity of LUTS significantly increased in the individuals with MetS ( = .002). In individuals with MetS, age, HbA1c, and cerebrovascular disease (CVD) were associated with IPSS. For OABSS, age, HbA1c, thyroid-stimulating hormone (TSH), coronary artery occlusive disease, and CVD were identified as predictors. CONCLUSIONS: We confirmed the positive correlation between MetS and BPH/LUTS in Korean. Factors including TSH and atherosclerosis affected LUTS in individuals with MetS. These findings suggested a potential role of thyroid hormones and atherosclerosis in the etiology and treatment of BPH/LUTS in patients with MetS.

Previous studies indicated that the relative length of the index and ring finger (2D:4D ratio) of AGA patients was lower than control. However, the correlation between 2D:4D ratio and disease severity is unclear. In this study, we sought to evaluate the relationship between digit ratio of the right hand and AGA severity in male patients. The cross-sectional study was performed. Hamilton-Norwood scale was used to assess severity. The finger lengths of the right hand were measured using a digital caliper. Our study found that the lower the right-handed 2D:4D ratio, the greater the risk of developing AGA and that the severity of AGA increases with age. Patients with moderate and severe AGA (grade 3 and above) had lower 2D:4D ratios and higher average age compared with patients with mild AGA (Norwood grade 2). Patients aged ≥37.5 with a 2D:4D ratio <0.947 were six times more likely to have moderate-to-severe androgenetic alopecia compared with the reference group (OR: 6.11; 95% CI: 1.96-19.04). Combining 2D:4D ratio and older age may help predict the severity risk of AGA, and offer a clinically accessible, non-invasive approach for patients to easily predict their future severity.

DATA SOURCES: We searched the electronic databases of Pubmed, Embase, Cochrane, and web of science. Published studies have been collected from these databases. Search terms include RE PCa, with a deadline of 31 March 2022. MAIN RESULTS: These studies showed significant improvements of body composition(Lean body mass MD: 1.12 95% CI [0.48, 1.76], < 0.01; Body fat rate MD: -1.12 95% CI [-1.99,-0.24], < 0.05; Appendicular skeletal mass MD: 0.74 95% CI [0.45, 1.03], < 0.01) and physical function (leg press MD: 77.95 95% CI [38.90, 117.00], < 0.01; stair climb MD:-0.30 95% CI [-0.49, -0.12], < 0.01). In addition, the improvement of Body fat mass (MD: -0.21 95% CI [-0.79, 0.37], > 0.05), 400 m walk (MD: -21.74 95% CI [-45.53, 2.05], > 0.05) and times up and go (MD: -0.50 95% CI [-1.03, 0.03], > 0.05) were not obvious. Subgroup analyses showed that RE for ≥ 6 months (compared with RE intervention for < 6 months) and starting exercise immediately after androgen deprivation therapy (ADT) (compared with delayed exercise after ADT) resulted in more significant improvements in body composition. Furthermore, the results showed that the exercise intensity of 8-12 RM significantly improved body composition. CONCLUSIONS: RE seems to be a promising approach in order to improve body composition and physical function in PCa patients to offset their treatment-related side effects. RE should be used as a means of rehabilitation and care for PCa. Starting exercise immediately after ADT and extending exercise time while choosing the right intensity can better improve the patients' body composition and function.

Bone turnover markers C-telopeptide of type I collagen (CTX) and procollagen I N-terminal propeptide (PINP) were assessed at baseline, 12 and 24 months. Bone mineral density (BMD) changes were evaluated after 24 months using dual-energy X-ray absorptiometry. Group T ( = 28) received TU both years. Group P ( = 27) received placebo first year and TU second year. RESULTS: CTX decreased in group P from 1055 (676-1344) to 453 (365-665) pmol/L ( < 0.001) and from 897 (679-1506) to 523 (364-835) pmol/L ( < 0.001) in T. PINP decreased by 4.30 ± 8.05 μg/L in group P ( = 0.030) and 4.64 ± 8.86 μg/L in T ( < 0.023) after first year of therapy. No femoral neck BMD changes were observed in 32 patients from both groups ( = 16 per group). Lumbar spine BMD increased (by 0.075 ± 0.114 g/cm; = 0.019) in group T following two years of treatment. CONCLUSIONS: We observed decreased CTX, decreased PINP and increased lumbar spine BMD after two years of testosterone treatment. CLINICAL TRIALS: NCT03792321; retrospectively registered trial on 4 January 2019.

Human brucellosis is quite uncommon in Elderly in Qatar. CASE REPORT: This report describes a case of Brucellosis in acute geriatric unit under Rumailah Hospital in Qatar. The patient was an 81-year-old Qatari Gentle man, functionally able to walk with minimal assistance and had mild cognitive impairment who presented with high-grade fever with chills, anorexia, low back pain and arthralgia for 10 days. The above complaints occurred often for 1 month and had fever intermittently. Lab investigations revealed as high CRP 117 mg/l, low Hb 9.1 g/dl and mild elevation in ALP (151 µ/l) with normal leukocyte and platelet count. His blood culture positive for with high brucella Antibody titter 1:1280. The diagnosis made as Brucellosis. DISCUSSION: The clinical manifestations of Brucellosis are fever, night sweating, chills, arthralgia and loss of appetite. It seems pyrexia of unknown origin without other symptoms is most common presentation of Brucellosis in old age. The confirmation of Brucellosis made with serological tests, with significantly high titer, in the presence or absence of blood culture. Brucella antibody titers (≥1:160) are suggestive of active infection. Anemia and raised CRP and liver enzymes were the most prominent laboratory abnormalities in our patients. Previous study from Qatar reported that 41.7% had a history of raw milk consumption and 12.5% had a history of animal contact. The objectives of Brucellosis treatment include the prevention of complications and relapse. CONCLUSION: Our case presented with classical symptoms and received appropriate treatment on time. However, atypical clinical presentation and lack of specific history taking can delay diagnosis and treatment; it leads to serious clinical disease progression with increased complications. From this case study, we would contribute to optimal assessment and to keep differential diagnosis for unknown cause of fever can be Brucellosis in geriatric population.
