Purpose: The purpose of this study is to retrospect and summarize clinical efficiency and experience of the free superficial palmar branch of radial artery (SPBRA) flap for soft-tissue reconstruction in distal digital injury. Method: 13 patients with soft-tissue defect of finger, reconstructed by the free superficial palmar branch of radial artery (SPBRA) flap in our department from January 2020 to January 2022, were reviewed. After 6–12 months of follow-up, evaluated the treatment effect of the fingers reconstructed by SPBRA flap. Results: All the flaps in our series application were survival uneventful, and all the donor sites were closed primarily without complications or obvious scarring. The flaps were soft in texture and satisfactory in appearance and function. The flaps with the median nerve palmar cutaneous branch had a good sensation recovery. Measurement of two-point discrimination (TPD) ranged from 6 to 10 mm. All patients were satisfied with the aesthetic appearance. According to the Evaluation Trial Standards of Upper Limb Partial Function of Hand Surgery of Chinese Medical Association, the results were graded as excellent in 11 cases and good in 2 cases. Conclusion: The SPBRA perforator flap has the advantages of simple operation, soft texture, good appearance and function, and is credible and useful for reconstructing various finger injuries.

Objective: The protective role of Lactobacillus iners in the vaginal microbiota has been questioned. Recent studies have shown that L. iners is the dominating taxon in a large subset of women worldwide. The aim of this study was to identify sociodemographic, behavioural and clinical variables associated with L. iners-dominated community state type (CST) III in Brazilian women of reproductive age.Participants and Methods: This study leveraged microbiota compositional data generated by sequencing of the V3-V4 16S rRNA gene from vaginal samples collected from 442 participants enrolled in a previous cross-sectional study that included 609 women in five geographical regions of Brazil. A total of 167 (27.4%) participants were excluded from the current study as they did not present a Lactobacillus-dominated vaginal microbiota. Data on sociodemographic and behavioural characteristics of the study population were obtained through face-to-face interviews. Participants were assigned to two study groups: those with L. iners-dominated CST III (n=222) and those with three distinct CSTs (I, II or V) dominated by another Lactobacillus spp. (n=220). Logistic regression analysis using a stepwise method was performed to test association between CST III and participants' characteristics, considering their OR and 95% CIs.Results: Among the population characteristics assessed, L. iners-dominated CST III was independently associated with having two or more sexual partners (OR 3.27; 95% CI 1.50 to 7.11) and microscopic detection of Candida sp. on vaginal smears (OR 2.24; 95% CI 1.02 to 4.89). Other characteristics were inversely associated with CST III, including condom use (OR 0.59; 95% CI 0.38 to 0.91), higher educational level (OR 0.61; 95% CI 0.41 to 0.91) and diet containing milk/dairy intake (OR 0.43; 95% CI 0.20 to 0.90).Conclusion: Unprotected sex practices, number of sexual partners and lower educational levels may be useful for identifying women with L. iners-dominated microbiota and its suboptimal protective properties. L. iners microbiota does not seem to provide optimal protection against Candida sp. colonisation, warranting further investigation. [ABSTRACT FROM AUTHOR]
