BACKGROUND
Injection treatments have been proposed as novel treatment options for Vulvovaginal Atrophy of Menopause (VVA) also known as Genitourinary Syndrome of Menopause (GSM). However, to date data about these treatments are poor.
OBJECTIVE
To assess all available injection treatments for VVA.
METHODS
A systematic review was performed by searching five electronic databases for peer-reviewed studies that assessed injection treatments for VVA.
RESULTS
Eight studies (7 observational and 1 randomized) with 236 women were included. Assessed injection materials were: autologous platelet-rich plasma (PRP) + hyaluronic acid (HA), not cross-linked HA plus calcium hydroxyapatite (NCLHA + CaHA), micro-fragmented adipose tissue (MFAT), hyaluronan hybrid cooperative complexes (HCC), crosslinked HA, microfat and nanofat grafting + PRP, and PRP alone. Improvement in GSM symptoms after treatment was assessed through Visual Analogic Scale (VAS) for GSM symptoms or patient satisfaction, several validated questionnaires (FSFI, VHI, FSD, SF12, ICIQ UI SF, PGI-I, FSDS-R, VSQ), symptoms severity, changes in vaginal mucosa thickness, flora, pH, and expression on vaginal mucosal biopsies of Procollagen I and III and ki67 immunofluorescence or COL1A1 and COL3A1 mRNA. Injection treatments showing significant improvement in GSM-related symptoms were: (i) HCC in terms of VAS for GSM symptoms and FSFI score; (ii) Crosslinked HA in terms of VAS for GSM symptoms, FSFI and VHI score, COL1A1 and COL3A1 mRNA expression on vaginal mucosal biopsies; (iii) NCLHA + CaHA in terms of FSFI score; (iv) PRP + HA in terms of VHI, FSD and SF12 score; (v) microfat and nanofat grafting + PRP in terms of VHI score and FSDS-R score; (vi) PRP alone in terms of VHI and VSQ scores.
CONCLUSIONS
All assessed injection treatments except for MFAT seem to lead to significant improvement in VVA symptoms on validated questionnaires. Further studies are necessary in the field.

Review
Supplementation of vitamin D isolated or calcium-associated with bone remodeling and fracture risk in postmenopausal women without osteoporosis: A systematic review of randomized clinical trials.
Menopause and vitamin D deficiency increase bone reabsorption and bone fracture risk in women in postmenopause, and vitamin D supplementation may improve bone health and decrease bone fracture risk. This study aims to discuss the effect of vitamin D supplementation, isolated or calcium-associated, on remodeling and fracture risk bone in women in postmenopause without osteoporosis. This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO database registration: CRD42022359796). A search was conducted in four databases and gray literature using MeSH and similar terms related to supplements, vitamin D, calcium, remodeling, and fracture bone, without the restriction of language and year of publication. A total of 3460 studies were identified, and nine were selected. Vitamin D supplementation increased 25-hydroxyvitamin D levels ≥10 ng/mL and decreased parathyroid hormone secretion dependent on baseline levels. The doses of 400 IU of vitamin D improved the percentage of carboxylated osteocalcin, whereas 800 to 1000 IU combined with calcium resulted in reduced, improved, or maintained bone mineral density and reduced alkaline phosphatase levels. However, 4000 IU alone or combined with calcium for 6 mo did not improve C-telopeptide and procollagen type 1 peptide levels. Additionally, 15 000 IU/wk increased the cortical area of metacarpal bone, whereas 500 000 IU of vitamin D annually for 5 y did not contribute to reducing the fracture risk and falls. Only one study found a reduction in fracture risk (dose of 800 IU of vitamin D plus 1200 mg of calcium). Thus, the vitamin D supplementation, alone or calcium-associated, improved the status of 25-hydroxyvitamin D and bone remodeling, but it was not possible to assert that it reduced fracture bone risk in postmenopausal women.

Meta-Analysis Review
AIM
The effects of vitamin D administration on bone turnover markers (BTMs) in adults are controversial. Thus, we carried out a meta-analysis of available randomised controlled trials (RCTs) to examine the impact of vitamin D supplementation on BTMs.
METHODS
To identify relevant RCTs, we searched the PubMed/MEDLINE, Web of Science, Scopus, Cochrane Library and Embase databases for manuscripts published up to July 2022. The present study was conducted in agreement with the PRISMA guidelines. Weighed mean difference (WMD) and 95% confidence intervals (CI) were used to calculate the magnitude of the effect of the intervention.
RESULTS
A total of 42 RCTs were included in the meta-analysis. The age of the participants enrolled in the RCTs ranged from 19.4 to 84 years. The pooled results depicted a decrease in deoxypyridinoline (DPD) concentrations (WMD: -1.58 nmol/mmol, 95% CI: -2.55, -.61, p = .001) following vitamin D supplementation. In addition, subgroup analyses demonstrated that vitamin D administration notably reduced procollagen type I N-terminal propeptide (PINP) levels in individuals aged >50 years and led to a pronounced decrease in alkaline phosphatase (ALP) values when the intervention lasted >12 weeks. No significant effect was observed on other BTMs, for example, collagen type 1 cross-linked C-telopeptide (CTX) and osteocalcin (OC) levels.
CONCLUSION
Vitamin D administration decreases DPD, PINP and ALP levels, indicating a reduced bone turnover following the intervention. Other BTMs, for example, CTX or OC values, were not affected by vitamin D prescription. Vitamin D supplementation may exert a positive effect on some important BTMs.

OBJECTIVE
Reference intervals for plasma P1NP and β-CTX in children and adolescents from several studies have recently been published. The aim of this study was to combine the available data into a set of reference intervals for use in clinical laboratories.
DESIGN AND METHODS
A systematic literature search for primary studies reporting reference intervals for plasma P1NP and β-CTX in infants, children and adolescents using the Roche methods was carried out. Reference limits were extracted. For each year of age, mean upper and lower reference limits were calculated, weighted by the number of subjects in each study, and were plotted against age. Proposed reference limits were developed from the weighted mean data with age partitions determined pragmatically.
RESULTS
Reference limits for clinical use for females to 25 years and males to 18 years, based on the weighted mean reference data, are presented. Ten studies contributed to the pooled analysis. The proposed reference limits are identical for males and females <9 years age, prior to the pubertal growth spurt. For β-CTX, the weighted mean reference limits showed relatively constant values during the pre-pubertal years but a marked increase during puberty before a rapid decline towards adult values. Those for P1NP showed high values declining rapidly in the first 2 years of life, followed by a modest increase during early puberty. Limited published information for late adolescent and young adult subjects was noted.
CONCLUSIONS
The proposed reference intervals may be useful for clinical laboratories reporting these bone turnover markers measured by the Roche assays.
