This systematic review and meta-analysis aimed to estimate the prevalence of pregnancy- and lactation-associated osteoporosis in postpartum women within 1 year of delivery. We searched MEDLINE via PubMed and Igaku Chuo Zasshi for articles published in English or Japanese from the inception of the database to September 2021. Two researchers independently screened and included observational studies reporting the prevalence of pregnancy- and lactation-associated osteoporosis in postpartum women within 1 year of delivery. Of the 3,425 screened records, 8 articles centered on postpartum women were included in the review. Seven studies used dual-energy X-ray absorptiometry for assessing bone mineral density, while one used a quantitative ultrasound method. In the seven studies that used dual-energy X-ray absorptiometry, the parameters used to define osteoporosis were the T-score (two studies), Z-score (three studies), both T- and Z-scores (one study), and young adult mean (one study). Evaluation timeframes included 1 week (three studies), 1-2 months postpartum (three studies), and 1 week to 12 months postpartum (one study). The estimated prevalence of pregnancy- and lactation-associated osteoporosis defined by dual-energy X-ray absorptiometry was as follows: lumbar spine (six studies), 5% (95% confidence interval [CI], 0-13; heterogeneity [I 2 ] = 99%) and femoral neck (three studies), 12% (95% CI, 0-30; I 2 = 99%). Pregnancy and lactation were found to elevate the fracture risk in women, underscoring the necessity for a standardized assessment in diagnosing pregnancy- and lactation-associated osteoporosis. This imperative step aims to enable early detection and treatment of bone mineral loss among postpartum women.

Since itching without rash frequently among older adults' population, study about skin properties of itching without rash is important to develop prevention methods. Therefore, this study explored the skin properties related to itching without rash and the factors associated with them. A correlation, predictive designs study was conducted at Indonesian Long-term Care (LTC) facilities. Skin properties including skin barrier function and skin inflammation were examined by photographs (macroscopic and microscopic), stratum corneum (SC) hydration, skin Potential of Hydrogen (pH), and skin blotting. Itching experience and skincare behavior were obtained by questionnaire. The itching-related skin properties and associated factors were analyzed. A total of 405 residents participated in this study, with mean age was 74 years. The prevalence of itching on the whole body was 69.1%, and 50.3% of those manifesting itching on the left forearm involved itching without macroscopic abnormalities (itching without rash). SC hydration, skin pH, albumin and nerve growth factor β (NGFβ) were associated with itching without rash (p = 0.007, 0.012, < 0.001, and < 0.001, respectively). Additionally, factors associated with skin properties were age, sex, sun exposure experience, skincare, and hygiene care in the linear regression analysis. Measurement of skin biomarkers using skin blotting was a possible objective measurement of itching skin properties without rash regardless of the environmental condition.

Nocturia and its related arousal may impair the quality of life and increase the risk of falls in older adults. This study aimed to clarify the change in urination status during the main sleeping period within 1 year. We also aimed to examine the effects of a consultation for voiding behavior in addition to the traditional behavioral therapy on urination status during sleep in a group of independent community-dwelling older adults. A single-arm intervention study was conducted in 10 older adults, with a mean age of 80.1 years and nocturia frequency of 1-4 times/day. Natural changes in urination status were observed between 2016 and 2017. Participants received traditional behavioral therapy and a consultation related to voiding behavior four times from summer 2017 to spring 2018. Urination status was monitored using sensing devices placed in the participant's home. The average time staying in the toilet significantly increased after 1 year. Although this parameter significantly decreased after the first consultation in 2017, this change was not observed with the subsequent consultation. A combination of traditional behavioral therapy and consultation for voiding behavior may be effective in improving urination status during the main sleeping period.

Previous studies have proposed that pelvic misalignment may be associated with stress urinary incontinence through a decrease in the contractile function of the pelvic floor muscles; however, this relationship remains unclear. This study aimed to clarify the relationship between low back pain, an indication of pelvic misalignment, and stress urinary incontinence at 3 months postpartum. We conducted a cross-sectional study of women who gave birth to full-term babies between July 2008 and July 2009. Stress urinary incontinence was defined as urinary leakage when coughing, sneezing, or exercising. Low back pain was defined as pain between the ribs and gluteal sulcus in the preceding 2 months. Of the 228 subjects included in the study, the prevalence of stress urinary incontinence was 22.8% (n = 52). The prevalence of low back pain in the stress urinary incontinence group was significantly higher than that in the non-stress urinary incontinence group (78.8% [n = 41] vs. 57.4% [n = 101]; p = 0.005). Stress urinary incontinence was associated with older age, primiparity, vaginal delivery, and low back pain at 3 months. In conclusion, low back pain was associated with stress urinary incontinence after adjusting for pregnancy and delivery factors, suggesting pelvic misalignment contributes to the development of stress urinary incontinence. We propose that including care for pelvic misalignment in pelvic floor muscle training, the treatment of choice for stress urinary incontinence, could be beneficial.

Persistence of urinary incontinence (UI) after robot-assisted radical prostatectomy (RARP) is a bothersome problem because of its negative effect on the patient's quality of life (QOL). This study aimed to evaluate the effect of transperineal ultrasound (TPUS)-guided pelvic floor muscle training (PFMT) on prolonged UI after RARP. Thirty men with stress UI persisting for > 1 year after RARP underwent biofeedback PFMT using TPUS once every 2-3 weeks for 3 months. The frequency and duration of sustaining pelvic floor muscle (PFM) contractions were assessed using ultrasound imaging. The severity of UI and UI-related QOL were evaluated using a 24-hour pad test and the incontinence quality of life (I-QOL) questionnaire. Twenty-four men (mean age, 72.2 years) completed the TPUS-guided PFMT. The mean duration from RARP to PFMT was 1,228.9 days. The mean cumulative session and the total duration of TPUS-guided PFMT were 4.6 times and 73.3 days, respectively. Compared with the data before TPUS-guided PFMT, the frequency of PFM contractions and duration of sustaining contraction significantly improved after TPUS-guided PFMT (p < 0.05). Additionally, the total amount of urinary leakage after TPUS-guided PFMT was reduced significantly (248.6 ± 280.6 g vs. 397.0 ± 427.0 g, p = 0.024). The I-QOL score was significantly increased after TPUS-guided PFMT (72.1 ± 16.8 vs. 61.0 ± 19.0, p < 0.001). TPUS-guided PFMT may be effective in improving prolonged UI occurring > 1 year after RARP.

We described fecal retention during the defecation cycles of adults with functional constipation via ultrasonography (US) of the large intestine. US was performed continuously after the last defecation until the next defecation. We defined the fecal finding level on US as follows: weak fecal retention, a marginally high echo in the colonic lumen; or strong fecal retention, a strongly echoic colon lumen with showing a crescent-shaped acoustic shadow on transverse images and haustrations on longitudinal images. The findings confirmed weak fecal retention in the colon throughout the defecation cycle and a pattern of strong fecal retention in the descending and sigmoid colon and over the colon, including the transverse colon and ascending colon, in patients with functional constipation.

The aim of this study was to assess rectal feces storage condition by a pocket-size ultrasonography (PUS) in healthy adults so as to define normal rectal defecation desire. Participants were first assessed rectum by PUS imaging immediately after defecation desire (pre-defecation). Nurses checked the amount and quality of the participants' feces using King's Stool Chart and Bristol stool scale. Finally, PUS was performed for defecation with no defecation desire (post-defecation). Pre-defecation PUS detected high echo area in all patients. All of the post-defecation PUS did not detect high echo area (perfectly no recognizable high echo area in 54.5%, high echo line in 36.4%, and low echo of entire circumference in 9.1% of the patients). Average diameter of rectal crescent was 4.22 ± 0.8 cm. Bristol Stool Scale 1 or 2 (indicating hard stool) of pre-defecation PUS indicated high echo area and acoustic shadow in 100% of the patients. This study showed that healthy adult with defecation desire had high average rectal echo area of 4.0 cm in diameter. PUS may be able to define the rectum diameter for defecation desire of elderly people. PUS is capable of assessing fecal retention of the rectum for point-of-care examinations in home care.
