RESUMEN
BACKGROUND & AIMS: Studies have shown evidence of gut dysbiosis in individuals with autism spectrum disorder (ASD). Various microbiome-modifying treatments, including probiotics, have been proposed. This review systematically assessed the evidence on the effects of probiotics on core autism symptoms in children with ASD. METHODS: We performed a comprehensive literature search in Medline, Embase, CENTRAL, PsycInfo, and clinical trial registries, up to March 2023, and updated on January 10, 2024. Randomized controlled trials (RCTs) of parallel-group and cross-over designs were eligible. The population included individuals below 20 years of age diagnosed with ASD. Trials evaluating the effects of probiotics (any strain or dose) compared to placebo, no treatment, or another intervention were included. The outcomes of interest included the core autism symptoms: deficits in social skills, communication skills, and restricted, repetitive behaviors. No language restrictions were applied. Studies were excluded if an additional active compound was administered. The risk of bias was assessed using the Revised Cochrane Risk of Bias tool (RoB 2). This review was registered in PROSPERO (CRD42023393000). RESULTS: In total, 12 RCTs assessing 630 participants were included. A borderline significant beneficial effect of probiotics on core ASD symptoms was found (8 RCTs, mean difference -0.21; 95% CI -0.39 to -0.03). Subgroup analysis according to study type showed a significant positive effect in parallel group trials (6 RCTs, mean difference -0.26; 95% CI -0.48 to -0.05). The pooled effect estimates for the other outcomes didn't reveal significant differences between the groups. Importantly, the risk of bias was high in nine studies. CONCLUSIONS: Available data do not provide high-quality evidence supporting the use of probiotics for ASD symptoms in children.
RESUMEN
OBJECTIVE: The dogma of probiotic strain-specificity is widely accepted. However, only the genus- and species-specific effects of probiotics are supported by evidence from clinical trials. The aim of this rapid review was to assess clinical evidence supporting the claim that the efficacy of probiotics in the pediatric population is strain-specific. METHODS: The Cochrane Library, MEDLINE, and EMBASE databases were searched (up to August 2022) for randomized controlled trials (RCTs) conducted in children aged 0-18 years evaluating the effects of prophylactic or therapeutic administration of probiotics (well-characterized at the strain level) for conditions such as antibiotic-associated diarrhea, acute diarrhea, necrotizing enterocolitis, respiratory tract infections, Helicobacter pylori infection, and atopic dermatitis. To allow evaluation of strain-specificity, a trial could only be included in the review if at least one additional RCT assessed the effect of a different strain of the same species against the same comparator. RCTs without proper strain-level data were excluded. In the absence of identifying head-to-head strain versus strain RCTs, indirect comparisons were made between interventions. RESULTS: Twenty-three RCTs were eligible for inclusion. Out of the 11 performed comparisons, with 1 exception (two Lacticaseibacillus paracasei strains in reducing atopic dermatitis symptoms), no significant differences between the clinical effects of different strains of the same probiotic species were found. CONCLUSIONS: Head-to-head comparison is an optimal study design to compare probiotic strains, but such comparisons are lacking. Based on indirect comparisons, this rapid review demonstrates insufficient clinical evidence to support or refute the claim that probiotic effects in children are strain-specific.

BACKGROUND: Alopecia areata (AA) is an autoimmune form of hair loss, which may affect any hair-bearing area. It has been suggested that AA is associated with an increased risk of metabolic and cardiovascular comorbidities. AIM: To evaluate the early predictors of cardiovascular disease [endothelial function (EF) and arterial stiffness (AS)] in patients with AA without prior cardiovascular disease, and compare with healthy controls (HCs). METHODS: In total, 52 patients with AA (38 women and 14 men; mean age 41 years, range 30-52 years) and 34 HCs, matched for age, sex and body mass index, were enrolled in the study. EF, expressed as reactive hyperaemia index (RHI), and AS, identified by augmentation index at 75 beats/min (AI@75) were assessed with the use of the Endo-PAT 2000 device. Endothelial dysfunction (ED) was defined as RHI value ≤1.67. RESULTS: ED was observed in 22 of 52 patients with AA (42%) and in 4 of 34 HCs (12%) (P < 0.01). Moreover, mean RHI was lower in patients with AA compared with HCs (1.90 ± 0.31 vs. 2.11 ± 0.45; P = 0.03). There was no significant difference in AI@75 between patients with AA and HCs. CONCLUSIONS: Patients with AA show abnormalities in early predictors of cardiovascular diseases. Regular cardiovascular screening might be appropriate for patients with AA.

Background: Endometriosis is a chronic inflammatory condition characterized by the presence of endometrial-like tissue outside of the uterine cavity. It affects approximately 6-12% among reproductive-age women. Laparoscopy is still the gold standard for diagnosing it. Since an average of couple of years elapses from the onset of symptoms to the definitive diagnosis, analysis of symptoms could serve as a non-invasive diagnostic tool. Methods: An anonymous survey was distributed online in November 2019. It contained 23 closed questions, which covered two areas: knowledge and awareness of endometriosis symptoms and its presence among respondents. Results: A total of 3319 women completed the survey, of which 328 were diagnosed with endometriosis (9.9%). The symptoms of endometriosis most often indicated by the general population were infertility and dysmenorrhea. In contrast, those least frequently indicated were painful defecation and dysuria. Respondents suffering from endometriosis indicated that they often or sometimes experienced dysmenorrhea (83%, n = 273), pelvic pain not related to menstruation (72%, n = 235), dyspareunia (68%, n = 223) and painful defecation or dysuria (40%, n = 132). Conclusions: Since the search for a non-invasive diagnostic endometriosis marker has been conducted for many years without success so far, it seems that awareness of the clinical presentation and reported symptoms may help to provide earlier diagnoses.

Noncicatricial patchy alopecia of the scalp and focal areas of skin hypopigmentation imply a diagnosis of alopecia areata and vitiligo. We present a case of a 22-year-old patient in whom these symptoms were associated with positive spirochete reactions, which allowed making a diagnosis of syphilitic alopecia coexisting with leukoderma syphiliticum. Skin lesions and hair loss resolved after the treatment with benzathine benzylpenicillin. Trichoscopy in syphilitic alopecia is nonspecific, but the absence of features typical for alopecia areata such as exclamation mark hairs may be important on an early stage of the clinical workup.
RESUMEN
OBJECTIVE: Introduction: Cervical cancer is an important issue of gynecologic oncology. The awareness of this disease, the attitude towards HPV vaccination and cytological screening play an important role in decreasing morbidity and mortality due to cervical cancer. The aim: To assess the various aspects of knowledge regarding cervical cancer, risk factors for this disease, the role of HPV infection and the attitude to primary (vaccination) and secondary (cytological screening) prevention among young women. PATIENTS AND METHODS: Materials and methods: The study was performed using CAWI method based on original questionnaire in electronic form. Online completing of the survey was voluntary and anonymous. RESULTS: Results: The study was conducted in a group of 2058 women aged 19-33. In total 98.4% of respondents came across the term "cervical cancer", 84.1% knew that cervical cancer could be prevented and the following were identified as the main risk factors: cervical cancer in closest relatives (85.3%) and HPV infection (81.9%). Although according to 82.0% of women HPV infection can be prevented by vaccination, only 18.4% of respondents were vaccinated. The main reason for non-vaccination was lack of knowledge about the availability of the vaccine (41.2%) and high price (32.0%). Of the unvaccinated people, 63.5% declare their will to be vaccinated in the future. Concerning secondary prevention, 98.6% of the respondents admitted that they knew the term "cytological examination", 89.0% indicated that this examination detected the presence of pre-cancerous lesions, and according to 58.4% of respondents, this test should be performed after sexual initiation. Despite the fact that 80.5% of respondents confirmed the fact of beginning sexual activity (44.4% of them had more than 1 partner), 17.1% of the respondents admitted that they didn't go to gynecologist yet. Approximately 84% of respondents believe that the amount of information on cervical cancer prophylaxis and HPV infections currently providing is insufficient. CONCLUSION: Conclusions: The basic terms regarding primary (vaccination) and secondary (prophylactic tests) prevention of cervical cancer have been widely known. However, the knowledge about specific risk factors, sexual behaviors contributing to HPV infection and, consequently, the ability to self-identify as belonging to higher risk group is insufficient. It is justified to conduct educational activities regarding the assessment of risks related to cervical cancer addressed to young women. Together with education, HPV vaccination and secondary prevention programs require financial support.
