Association between body mass index, metabolic syndrome and common urologic conditions: a cross-sectional study using a large multi-institutional database from the United States.

INTRODUCTION: The study aims to determine whether body mass index (BMI), metabolic syndrome (MS) or its individual components (primary hypertension, type 2 diabetes mellitus and dyslipidemias) are risk factors for common urological diseases. MATERIALS AND METHODS: Cross-sectional study with data collected on February 28, 2022 from the TriNetX Research Network. Patients were divided in cohorts according to their BMI, presence of MS (BMI > 30 kg/m2, type 2 diabetes mellitus, primary hypertension and disorders of lipoprotein metabolism) and its individual components and its association with common urological conditions was determined. For each analysis, odds ratio (OR) with 95% confidence intervals were calculated. Statistical significance was assessed at p < .05. RESULTS: BMI > 30 kg/m2 was associated with increased risk of lithiasis, kidney cancer, overactive bladder, male hypogonadism, benign prostatic hyperplasia, and erectile dysfunction (p < .05). On the contrary, BMI was inversely associated with ureteral, bladder and prostate cancer (p < .05). In all urological diseases, MS was the strongest risk factor, with prostate cancer (OR = 2.53) showing the weakest and male hypogonadism the strongest (OR = 13.00) associations. CONCLUSIONS: MS and its individual components were significant risk factors for common urological conditions. Hence holistic approaches with lifestyle modification might prevent common urological disease.Key messagesOverall, metabolic syndrome is the strongest risk factor for all the analysed urological diseases.Abnormally high body mass index can be a risk or protective factor depending on the threshold and urological disease that are being evaluated.Metabolic syndrome and increased BMI should be considered important factors associated to the prevalence of common urological diseases.

Mortality and Urological Complications After Open Groin Hernia Repair in Local, General, and Regional Anesthesia: A Nationwide Linked Register Study.

BACKGROUND AND AIMS: The choice of anesthesia method may influence mortality and postoperative urological complications after open groin hernia repair. We aimed to investigate the association between type of anesthesia and incidence of urinary retention, urethral stricture, prostate surgery, and 1-year mortality after open groin hernia repair. MATERIALS AND METHODS: Data were linked from the Danish Hernia Database, the national patient register, and the register of causes of death. We investigated data on male adult patients receiving open groin hernia repair from 1999 to 2013 with either local anesthesia, regional anesthesia, or general anesthesia. In relation to the type of anesthesia, we compared mortality and urological complications up to 1 year postoperatively. We adjusted for covariates in a logistic regression assessing urological complications and with the Cox regression assessing mortality. RESULTS: We included 113,069 open groin hernia repairs in local anesthesia, regional anesthesia, or general anesthesia. The risk of urinary retention adjusted for covariates was higher after both general anesthesia (adjusted odds ratio = 1.64, 95% confidence interval = 1.05-2.57, p = 0.031) and regional anesthesia (odds ratio = 2.99, 95% confidence interval = 1.67-5.34, p < 0.0005) compared with local anesthesia. The adjusted risk of prostate surgery was also higher for both general anesthesia (odds ratio = 1.58, 95% confidence interval = 1.23-2.03, p < 0.0005) and regional anesthesia (odds ratio = 1.90, 95% confidence interval = 1.40-2.58, p < 0.0005) compared with local anesthesia. Type of anesthesia did not influence 1-year mortality or the risk for urethral stricture. CONCLUSION: Patients undergoing open groin hernia repair in local anesthesia experience the lowest rate of urological complications and have equally low mortality compared with patients undergoing repair in general anesthesia or regional anesthesia.

Multiple sclerosis and related challenges to young women's health: Canadian expert review.

Multiple sclerosis (MS) is among the most common chronic neurological diseases, with a highly variable degree of disability during its long-term course. The majority of patients develop significant permanent disability later in life. MS is often diagnosed in women of childbearing age, with a 3:1 ratio of young women to young men with MS. Comorbidities such as depression, anxiety, migraines and reproductive, urological and bowel issues are common and negatively impact patients' quality of life. The objective of this supplement is to review the most common comorbidities occurring in young women with MS, and to propose a multidisciplinary, holistic approach to management.

Evaluation of the efficacy and safety of deferiprone compared with deferasirox in paediatric patients with transfusion-dependent haemoglobinopathies (DEEP-2): a multicentre, randomised, open-label, non-inferiority, phase 3 trial.

BACKGROUND: Transfusion-dependent haemoglobinopathies require lifelong iron chelation therapy with one of the three iron chelators (deferiprone, deferasirox, or deferoxamine). Deferasirox and deferiprone are the only two oral chelators used in adult patients with transfusion-dependent haemoglobinopathies. To our knowledge, there are no randomised clinical trials comparing deferiprone, a less expensive iron chelator, with deferasirox in paediatric patients. We aimed to show the non-inferiority of deferiprone versus deferasirox. METHODS: DEEP-2 was a phase 3, multicentre, randomised trial in paediatric patients (aged 1 month to 18 years) with transfusion-dependent haemoglobinopathies. The study was done in 21 research hospitals and universities in Italy, Egypt, Greece, Albania, Cyprus, Tunisia, and the UK. Participants were receiving at least 150 mL/kg per year of red blood cells for the past 2 years at the time of enrolment, and were receiving deferoxamine (<100 mg/kg per day) or deferasirox (<40 mg/kg per day; deferasirox is not registered for use in children aged <2 years so only deferoxamine was being used in these patients). Any previous chelation treatment was permitted with a 7-day washout period. Patients were randomly assigned 1:1 to receive orally administered daily deferiprone (75-100 mg/kg per day) or daily deferasirox (20-40 mg/kg per day) administered as dispersible tablets, both with dose adjustment for 12 months, stratified by age (<10 years and ≥10 years) and balanced by country. The primary efficacy endpoint was based on predefined success criteria for changes in serum ferritin concentration (all patients) and cardiac MRI T2-star (T2*; patients aged >10 years) to show non-inferiority of deferiprone versus deferasirox in the per-protocol population, defined as all randomly assigned patients who received the study drugs and had available data for both variables at baseline and after 1 year of treatment, without major protocol violations. Non-inferiority was based on the two-sided 95% CI of the difference in the proportion of patients with treatment success between the two groups and was shown if the lower limit of the two-sided 95% CI was greater than -12·5%. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with EudraCT, 2012-000353-31, and ClinicalTrials.gov, NCT01825512. FINDINGS: 435 patients were enrolled between March 17, 2014, and June 16, 2016, 393 of whom were randomly assigned to a treatment group (194 to the deferiprone group; 199 to the deferasirox group). 352 (90%) of 390 patients had ß-thalassaemia major, 27 (7%) had sickle cell disease, five (1%) had thalassodrepanocytosis, and six (2%) had other haemoglobinopathies. Median follow-up was 379 days (IQR 294-392) for deferiprone and 381 days (350-392) for deferasirox. Non-inferiority of deferiprone versus deferasirox was established (treatment success in 69 [55·2%] of 125 patients assigned deferiprone with primary composite efficacy endpoint data available at baseline and 1 year vs 80 [54·8%] of 146 assigned deferasirox, difference 0·4%; 95% CI -11·9 to 12·6). No significant difference between the groups was shown in the occurrence of serious and drug-related adverse events. Three (2%) cases of reversible agranulocytosis occurred in the 193 patients in the safety analysis in the deferiprone group and two (1%) cases of reversible renal and urinary disorders (one case of each) occurred in the 197 patients in the deferasirox group. Compliance was similar between treatment groups: 183 (95%) of 193 patients in the deferiprone group versus 192 (97%) of 197 patients in the deferisirox group. INTERPRETATION: In paediatric patients with transfusion-dependent haemoglobinopathies, deferiprone was effective and safe in inducing control of iron overload during 12 months of treatment. Considering the need for availability of more chelation treatments in paediatric populations, deferiprone offers a valuable treatment option for this age group.

Glutamine-enriched enteral nutrition in very low birthweight infants and allergic and infectious diseases at 6 years of age.

In a previous randomised controlled trial, we found that glutamine-enriched enteral nutrition in 102 very low birthweight (VLBW) infants decreased both the incidence of serious infections in the neonatal period and the risk of atopic dermatitis during the first year of life. We hypothesised that glutamine-enriched enteral nutrition in VLBW infants in the neonatal period influences the risk of allergic and infectious disease at 6 years of age. Eighty-eight of the 102 infants were eligible for the follow-up study (13 died, 1 chromosomal abnormality). Doctor-diagnosed allergic and infectious diseases were assessed by means of validated questionnaires. The association between glutamine-enriched enteral nutrition in the neonatal period and allergic and infectious diseases at 6 years of age was based on univariable and multivariable logistic regression analyses. Seventy-six of the 89 (85%) infants participated, 38 in the original glutamine-supplemented group and 38 in the control group. After adjustment, we found a decreased risk of atopic dermatitis in the glutamine-supplemented group: adjusted odds ratio (aOR) 0.23 [95% CI 0.06, 0.95]. No association between glutamine supplementation and hay fever, recurrent wheeze and asthma was found. A decreased risk of gastrointestinal tract infections was found in the glutamine-supplemented group (aOR) 0.10 [95% CI 0.01, 0.93], but there was no association with upper respiratory, lower respiratory or urinary tract infections. We concluded that glutamine-enriched enteral nutrition in the neonatal period in VLBW infants decreased the risk of atopic dermatitis and gastrointestinal tract infections at 6 years of age.

Diagnóstico y evolución de las malformaciones congénitas del riñón y vías urinarias: 1999-2005: Holguín 2007 / Diagnosis and evolution of congenital malformations of the kidney and urinary tract

Con el objetivo de evaluar la experiencia clínica en los Servicios de Nefrología y Urología del Hospital Pediátrico Provincial Docente Octavio de Concepción y de la Pedraja de Holguín se realizó un estudio descriptivo de 351 pacientes atendidos entre enero 1999 y diciembre 2005. En esta serie de 351 pacientes fueron diagnosticadas 535 malformaciones congénitas del riñón y vías urinarias de 19 tipos. El reflujo vesico ureteral primario, la estenosis de la unión ureteropiélica y el doble sistema excretor fueron en ese orden, las malformaciones más frecuentes, siendo la edad más común de diagnóstico durante el primer año de vida. La mayoría de los pacientes se presentaron con infección del tracto urinario y un número importante fueron asintomáticos. La ultrasonografía y la uretrocistografía miccional convencional resultaron una combinación efectiva para el diagnóstico de estas. La mayoría de los pacientes a los que se les realizó diagnóstico prenatal tenían una Hidronefrosis Congénita. La valva de uretra posterior fue la principal causa de insuficiencia renal crónica. Los grados I, II y III de reflujo vesico ureteral primario casi siempre desaparecen espontáneamente, siendo el tratamiento médico o conservador la piedra angular en el manejo de estos pacientes. Apreciamos una relación directa entre la nefropatía de reflujo y el grado de esta entidad.

Low ratios of sodium to potassium in the serum of 238 dogs.

Serum sodium:potassium (Na:K) ratios are often reported in biochemical studies of dogs, although their value has not been assessed. The aims of this study were to identify diseases associated with a low Na:K ratio in dogs and to compare their prevalence with the prevalence in dogs from the same referral hospital with normal Na:K ratios. A total of 238 dogs with a Na:K ratio less than 27 were identified from medical records. Sample contamination with edta was suspected in 74 cases (31 per cent) and these and two cases that had been supplemented with potassium were removed from the analysis. The remaining 162 cases and 147 control dogs were divided into five categories depending on the organ system affected. Among the cases there were significantly more in the endocrine category than among the control dogs. Hypoadrenocorticism was the most single common cause of a low Na:K ratio and affected 27 (16.7 per cent) of the cases. Other clinical problems associated with low Na:K ratios included different urogenital, cardiorespiratory and gastrointestinal diseases.

Lower urinary tract symptoms and erectile dysfunction; links for diagnosis, management and treatment.

Recent large-scale epidemiological studies have documented a strong association between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). This observation has two important scientific and clinical aspects: (i) to reveal the pathomechanism linking LUTS and ED and (ii) to consider this fact in the individual approach for diagnosis and management of these two disorders. The following hypotheses are under investigation to explain the relation between LUTS and ED: (i) an increased Rho-kinase activation, (ii) an alpha-adrenergic receptor imbalance, (iii) a decrease of NOS/NO in the endothelium, (iv) atherosclerosis affecting the small pelvis and (v) an autonomic hyperactivity, each affecting simultaneously bladder, prostate and penis. According to a recent randomized trial, sildenafil has a positive effect on LUTS yet not on uroflowmetry in men with LUTS and ED. Although further trials are mandatory, phosphodiesterase-5 inhibitors might play a role in the management of LUTS in the future. alpha-Blockers have no relevant effect on erectile function, tamsulosin leads to retrograde ejaculation in up to 10%. 5alpha-Reductase inhibitors are associated with ED, loss of libido and reduction of ejaculate volume in up to 10%. Transurethral and open prostatectomy induce retrograde ejaculation in up to 90% of patients while their impact on erectile function is still controversially discussed. Minimal invasive treatment options (laser prostatectomy, transurethral microwave thermotherapy) have a lower rate of retrograde ejaculation in the range of 20-70%. LUTS and ED are strongly linked although the exact mechanism is poorly understood. Men seeking for help for LUTS/benign prostatic hyperplasia should be assessed for different aspects of sexual dysfunction and informed regarding the impact of medication and surgery on sexual health.

[Primary prevention, health promotion, and compression of morbidity. Perspectives for urology]. / Primärprävention, Gesundheitsförderung und Morbiditätskompression. Perspektiven für die Urologie.

Prevention and health promotion are interventions which achieve compression of morbidity. This is well-advised from the viewpoints of both health economics and quality of life in an aging society. Only when preventive and health-promoting strategies have become a matter of course in the health care system can the challenges posed by the altered disease spectrum be met. Because of the frequency of age-associated diseases encountered in urological practice and the considerable influence it wields on quality of life, urology is a focus of attention. Prevention and health counseling will prove to be major tasks in the practice of urology, especially in the private sector. Viewed systematically, primary prevention is more medical and individual in character while health promotion is an aspect of health science geared toward a specific echelon or group. The mission of health policy and medical associations must be to design and evaluate programs for prevention and health promotion. This is uncharted territory for urology. Economic aspects specific to professional groups should not constitute the sole center of attention, even though these interests are legitimate. It is essential that the approach to primary prevention efforts be directed at specific echelons and groups to also reach fringe groups and socially weak groups in the population.

Endourologic procedures combined with other surgical and urologic interventions--early experience.

OBJECTIVES: To assess the feasibility of performing endourologic interventions combined with other operations during the same operative session. METHODS: Eighteen patients underwent simultaneous operations endourologically for upper urinary tract pathologic findings and other surgical and urologic indications. The operating time, technical feasibility, operative success, complications, hospital stay, and patient satisfaction were analyzed. RESULTS: The average patient age was 63 years (range 40 to 83). Five patients underwent percutaneous nephrolithotomy combined with either contralateral laparoscopic nephrectomy, contralateral open nephrectomy, radical retropubic prostatectomy, inguinal/umbilical hernia repair, transurethral resection of prostate, or cystolithotripsy. Thirteen patients underwent 15 retrograde endoscopic procedures (13 for stone disease and 2 for diagnostic purposes) that were combined with open contralateral nephrectomy, inguinal hernia repair, circumcision, closure of ileostomy, transurethral resection of bladder tumor, excision of lymphoma of thigh, drainage and sclerozation of hydrocele, or percutaneous gastrostomy. All procedures were successfully completed without complications. The average hospital stay was 5 days (range 3 to 6) in the percutaneous nephrolithotomy group and 2 days (range 1 to 5) in the retrograde endoscopic procedure group. The duration of hospitalization was related to the more complex operation; combining the procedures did not prolong it. The average follow-up was 11 months (range 3 to 24). All patients were highly satisfied because they were spared the need for more than one surgical session. CONCLUSIONS: Our results support the concept of performing simultaneous endourologic procedures and other operations during one surgical session. This approach obviates the need for repeated anesthesia, patient inconvenience, the psychological stress related to multiple operations, and reduces the total hospital stay.

Acaroid mite, intestinal and urinary acariasis.

AIM: To investigate epidemiology and pathogenic mite species of intestinal and urinary acariasis in individuals with different occupations. METHODS: A total of 1994 individuals were tested in this study. History collection, skin prick test and pathogen identification were conducted. The mites were isolated from stool and urine samples by saturated saline flotation methods and sieving following centrifugation, respectively. RESULTS: Among the 1994 individuals examined, responses to the skin prick test of "+++", "++", "+","+/-" and "-" were observed at frequencies of 3.96 % (79), 3.21 % (64), 2.31 % (46), 1.25 % (25) and 89.27 % (1780), respectively. A total number of 161 (8.07 %) individuals were shown to carry mites, with 92 (4.61 %) positive only for stool samples, 37 (1.86 %) positive only for urine samples and 32 (1.60 %) for both. The positive rate of mites in stool samples was 6.22 % (124/1994), being 6.84 % (78/1140) for males and 5.39 % (46/854) for females. No gender difference was observed in this study (chi(2)=1.77, P>0.05). The mites from stool samples included Acarus siro, TyroPhagus putrescentiae, Dermatophagoides farinae, D. pteronyssinus, Glycyphagus domesticus, G. ornatus, Carpoglyphus lactis and Tarsonemus granaries. The positive rate of mites in urine samples was 3.46 % (69/1994). The positive rates for male and female subjects were found to be 3.95 % (45/1140) and 2.81 % (24/854) respectively, with no gender difference observed (chi(2)=1.89, P>0.05). Mites species in urine samples included Acarus siro, Tyrophagus putrescentiae, T. longior, Aleuroglyphus ovatus, Caloglyphus berlesei, C. mycophagus, Suidasia nesbitti, Lardoglyphus konoi, Glycyphagus domesticus, Carpoglyphus lactis, Lepidoglyphus destructor, Dermatophagoides farinae, D. pteronyssinus, Euroglyphus magnei, Caloglyphus hughesi, Tarsonemus granarus and T. hominis. The species of mites in stool and urine samples were consistent with those separated from working environment. A significant difference was found among the frequencies of mite infection in individuals with different occupations (chi(2)=82.55, P<0.001), with its frequencies in those working in medicinal herb storehouses, those in rice storehouse or mills, miners, railway workers, pupils and teachers being 15.89 % (68/428), 12.96 % (53/409), 3.28 % (18/549), 2.54 % (6/236), 5.10 % (13/255) and 2.56 % (3/117), respectively. CONCLUSION: The prevalence of human intestinal and urinary acariasis was not associated with gender, and these diseases are more frequently found in individuals working in medicinal herb, rice storehouses or mills and other sites with high density of mites. More attention should be paid to the mite prevention and labor protection for these high-risk groups.

[The problem of paramedicine and the therapy of urologic patients]. / Otnosno problema parameditsina i terapiia na urologichno bolnite.

A questionnaire study covering a large number of urological patients is carried out in an attempt to establish the extent to which the services of paramedical healers are sought, as well as the underlying motivation involved. It is demonstrated that 13.12 per cent of the inquired refer to alternative medicine specialists. Usually it is a matter of patients with chronic and incurable conditions, such as nephrolithiasis, adenoma of the prostate gland, oncourological diseases, chronic prostatitis and cystalgia. Of the vast variety of healers, herbalists and extrasensory perception therapists appear to be the most attractive. Nearly one-third of the patients appear to be the most attractive. Nearly one-third of the patients attain temporary effect of a varying degree, estimated subjectively. All patients with some improvement have undergone parallel treatment by urologist and healer. The problem is comprehensively discussed.

[Incidence of urinary tract diseases among workers in the Masovian Refining and Petrochemical Plants in Plock 1978-1981]. / Czestosc wystepowania chorób narzadów ukladu moczowego u pracowników Mazowieckich Zakladów Rafineryjnych i Petrochemicznych w Plocku w latach 1978-1981.

The studies were aimed at estimation of the incidence rate of genito-urinary tract diseases among employees of the Mazovian Refining and Petrochemical Plants in Plock. In 1978-1981, 873 employees were examined, including 244 females and 629 males. Most of them, namely 572 (65%), were employed in those plants for more than 5 years. In 190 persons (21.8%) either history of urologic diseases (41 persons) or current diseases (149 persons) were found. The incidence rate of genito-urinary tract diseases was similar to that observed in general population. The studies are continued.
