Does Sexual Intercourse Position Have a Role in Occurrence of Coital Urinary Incontinence?

INTRODUCTION AND HYPOTHESIS: This study was aimed at investigating the hypothesis that sexual intercourse positions may have an impact on the occurrence of coital urinary incontinence (CUI) in women. METHODS: This case-control observational study enrolled 360 married, heterosexual, sexually active female participants with CUI. Each patient was evaluated using medical and sexual histories, questionnaires, physical examinations, and laboratory tests, including urodynamics. Participants were asked whether or not their intercourse positions had an impact on the occurrence of their CUI. Patients with intercourse position-dependent CUI were included in group 1, and those independent of it were allocated to group 2. The clinic and laboratory findings of the patient groups were compared. RESULTS: The patients' mean age was 47.24 ± 0.57 years. Of these women, 28.9% (n = 104) were in group 1, and 71.1% (n = 256) were in group 2. Group 1 had a lower mean age, body mass index, Charlson comorbidity index, number of urinary incontinence episodes, severity of CUI and incontinence, and pad weight than group 2 (p < 0.05). The rates of detrusor overactivity and penetration type of CUI were higher in group 1 than in group 2 (p < 0.0009, p = 0.009 respectively). According to logistic regression analysis, the likelihood of sexual position-related CUI was 3.5 times higher in women with detrusor overactivity. CONCLUSIONS: In certain patients, intercourse position is associated with the occurrence of CUI. This condition seems to be related to detrusor overactivity and is inversely associated with incontinence severity. However, further studies are necessary to explain this phenomenon.

Diagnostic value of voiding scores of the "International prostate symptom score" and the "Bristol female lower urinary system symptoms-short form" questionnaires in women with voiding dysfunction.

Introduction: We aimed to investigate the diagnostic value of International Prostate Symptom Score voiding symptom score (IPSS-VS) and Bristol Female Lower Urinary Tract Symptoms-short form voiding score (BFLUTS-VS) in female patients with urodynamically diagnosed voiding dysfunction. Methods: The medical records of female patients who underwent urodynamic examination between May 2007 and November 2021 for lower urinary tract complaints were retrospectively evaluated. A total of 1858 female patients were included in the study. Patients investigated between 2007 and 2014 were asked to fill the IPSS, and patients investigated after 2015 were asked to fill the BFLUTS-SF. Results: The mean age of the patients was 49.06 ± 0.33 in the IPSS group and 50.02 ± 0.47 in the BFLUTS group. On the pressure flow study, voiding dysfunction was found in 14.8% (n = 95) in the IPSS group and 15.1% (n = 183) in the BFLUTS group. The area under curve value was found to be 0.58 for IPSS and 0.64 for BFLUTS. Threshold values were found as >9 for IPSS-VS and >4 for BFLUTS-VS. The sensitivity, specificity, false negative, and false positive rates for IPSS-VS were 33.3%, 78.8%, 66.7%, and 21.2%, respectively. The same parameters were 45.5%, 78.9%, 54.5%, and 21.1% for BFLUTS-VS, respectively. Conclusion: The diagnostic performance of both the questionnaires was found to be low for diagnosing voiding dysfunction in female patients according to our data. Therefore, the assessment of the voiding phase in women should not solely rely on the current questionnaires. However, further studies using questionnaires including all voiding symptoms are required.

Primary coenzyme Q10 Deficiency-6 (COQ10D6): Two siblings with variable expressivity of the renal phenotype.

Primary coenzyme Q10 deficiency-6 (COQ10D6) is a rare autosomal recessive disorder caused by COQ6 mutations. The main clinical manifestations are infantile progressive nephrotic syndrome (NS) leading to end-stage renal disease and sensorineural deafness. A 7-year-old girl was diagnosed with steroid-resistant NS (SRNS) and an audiological work-up revealed bilateral sensorineural deafness. A renal biopsy demonstrated focal segmental glomerulosclerosis. Despite immunosuppressive therapy, her serum levels of creatinine increased and haemodialysis was indicated within 1 year after the diagnosis. Living-donor kidney transplantation was performed in the eighth month of haemodialysis. A diagnostic custom-designed panel-gene test including 30 genes for NS revealed homozygous c.1058C > A [rs397514479] in exon nine of COQ6. Her older brother, who had sensorineural hearing loss with no renal or neurological involvement, had the same mutation in homozygous form. COQ6 mutations should be considered not only in patients with SRNS with sensorineural hearing loss but also in patients with isolated sensorineural hearing loss with a family history of NS. The reported p.His174 variant of COQ8B was suggested to be a risk factor for secondary CoQ deficiency, while p.Arg174 appeared to improve the condition in a yeast model. Family segregation and the co-occurrence of biallelic p.Arg174 of COQ8B in a brother with hearing loss implied that the interaction of the altered COQ8B with the mutant COQ6 alleviated the symptoms in this family. CoQ10 replacement therapy should be initiated for these patients, as primary CoQ10 deficiency is considered the only known treatable mitochondrial disease.

Creating Individualized Education Material for Diabetes Patients Using the eDiabetes Platform.

Diabetes mellitus (DM) is a chronic disease that affects many people in Switzerland and around the world. Once diagnosed, a patient has to continuously monitor blood glucose, manage medications or inject insulin. Technical skills and competencies as well as knowledge on disease management have to be acquired right after being diagnosed. Diabetes consultants support patients in this process and provide educational material. While the process of generating patient-tailored material is currently complex and time consuming, in future, the eDiabetes platform can help. The platform developed in cooperation with the consulting section of the Swiss Diabetes Society offers the opportunity to create individual patient information and instructions to teach technical skills and knowledge on diabetes. Further, an integrated forum allows exchanging information and discussing issues regarding diabetes counselling on a secure platform. Usability tests showed that eDiabetes is easy to use and provides benefits for diabetes consultants and patients.

Synthesis and characterization of polycaprolactone for anterior cruciate ligament regeneration.

Anterior cruciate ligament (ACL) is the most frequently torn ligament in the knee, and complete healing is unlikely due to lack of vascularization. Current approaches for the treatment of ACL injuries include surgical interventions and grafting, however recent reports show that surgeries have 94% recurrency, and that repaired tissues are biomechanically inferior to the native tissue. These necessitate the need for new strategies for scar-free repair/regeneration of ACL injuries. Polycaprolactone (PCL) is a biodegradable and biocompatible synthetic polymer, which has been widely used in the connective tissue repair/regeneration attempts. Here, we report on the synthesis of PCL via ring opening polymerization using ε-caprolactone as the monomer, and ammonium heptamolybdate as a catalyst. The synthesized PCL was characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. It was then processed using electrospinning to form nanofiber-based scaffolds. These scaffolds were characterized in terms of surface as well as mechanical properties, and compared to the properties of commercially available PCL, and of native ACL tissue harvested from sheep. In addition, scaffolds fabricated with synthesized PCL were evaluated regarding their cell attachment capacity using human bone marrow mesenchymal stem cells (hBMSCs). Our findings demonstrated that the synthesized PCL is similar to its commercially available counterpart in terms of surface morphology and mechanical properties. In addition, fibrous scaffolds generated with electrospinning showed weaker mechanical properties visa vis native ACL tissue in terms of ultimate stress, and elastic modulus. Also, the synthesized PCL can accommodate cell attachment when tested with hBMSCs. Putting together, these observations reveal that the PCL synthesized in this study could be a good candidate as a biomaterial for ligament repair or regeneration.
