Meta-Analysis
BACKGROUND
Immune-mediated melanocyte-related pathogenesis in alopecia areata (AA) may cause sensorineural hearing loss (SNHL). However, the relation between AA and SNHL has been unclear. Therefore, we aimed to investigate this association between AA and SNHL.
METHODS
We performed a systematic review and searched MEDLINE and Embase on July 25, 2022, for cross-sectional, case-control, or cohort studies that examined the association of AA with SNHL. The Newcastle-Ottawa Scale was used to evaluate their risk of bias. A random-effects model meta-analysis was performed to obtain the mean differences in frequency-specific hearing thresholds between AA patients and age-matched healthy controls and the pooled odds ratio for SNHL in relation to AA.
RESULTS
We included 5 case-control studies and 1 cohort study, with none of them rated with high risk of biases. The meta-analysis showed AA patients had significantly higher mean differences in pure-tone hearing thresholds at 4,000 Hz and 12,000-12,500 Hz. The meta-analysis also found increased odds for SNHL among patients with AA (OR: 3.18; 95% CI: 2.06-4.89; I2 = 0%).
CONCLUSIONS
AA is associated with an increase of SNHL, especially at high frequencies. Otologic consultation may be indicated if AA patients present with hearing loss or tinnitus.

Meta-Analysis Review
OBJECTIVE
Alopecia is one of the most common adverse effects of chemotherapy, having a significant impact on the quality of life of patients who suffer from it. Among the interventions available for its prevention, scalp cooling (SC) is the most widely used. The aim of this study was to assess the efficacy and safety of the use of SC systems during chemotherapy sessions for the prevention or the reduction of the extent of chemotherapy-induced alopecia.
METHODS
A systematic review of the literature published up to November 2021 was carried out. Randomized clinical trials were selected. The main outcome measure was alopecia (hair loss>50%) during and after chemotherapy treatment. When possible, a quantitative synthesis of the results was performed through meta-analysis using the Stata v.15.0 software. The risk ratio (RR) of the variable alopecia, was estimated using a random effects model following the Mantel-Haenszel method. Statistical heterogeneity of the results was evaluated graphically and through the test of heterogeneity χ and the Higgins I statistic. Sensitivity analyses and subgroup analyses were performed.
RESULTS
13 studies were included, with a total of 832 participants (97.7% women). In most studies, the main chemotherapy treatment applied was anthracyclines or the combination of anthracyclines and taxanes. The results obtained indicate that SC prevents alopecia (loss>50%) by 43% compared to the control group (RR=0.57; 95% CI=0.46 to 0.69; k=9; n=494; I=63.8%). No statistically significant difference was found between the efficacy of automated and non-automated cooling systems (P=0.967). No serious short- or medium-term adverse events related to SC were recorded.
CONCLUSIONS
The results suggest that scalp cooling contributes to the prevention of chemotherapy-induced alopecia.

Review
Androgenetic alopecia is a condition that results in hair loss in both men and women. This can have a significant impact on a person's psychological well-being, which can lead to a decreased quality of life. We conducted a systematic review to evaluate the efficacy of using stem cells in androgenic alopecia. The search was conducted in MEDLINE via PubMed, Web of Science, and Scopus databases. The review was performed on data pertaining to the efficacy of using different types of stem cells in androgenic alopecia: quantitative results of stem cell usage were compared to the control treatment or, different types of treatment for female and male androgenetic alopecia. Of the outcomes, the density of hair was analyzed. Fourteen articles were selected for this review. During and after treatment with stem cells, no major side effects were reported by patients with alopecia. The use of stem cells in androgenic alopecia seems to be a promising alternative to the standard treatment or it could play the role of complementary therapy to improve the effect of primary treatment. However, these results should be interpreted with caution until they can be reproduced in larger and more representative samples.

Review
A systematic review of clinical trials using single or combination therapy of oral or topical finasteride for women in reproductive age and postmenopausal women with hormonal and nonhormonal androgenetic alopecia.
Female pattern hair loss (FPHL) is a hereditary form of hair loss in women and the most common patterned progressive hair loss in female patients with androgenetic alopecia (AGA). One of the best methods for treating hair loss in women is the finasteride treatment. This systematic review includes a summary of the pharmacology of finasteride and the effect of the drug on women, especially those in the menopausal age group, and is aimed at elucidating methods of preventing systematic side effects. A search of all published literature from 1999 to 2020 has been conducted with the use of PubMed/MEDLINE, Embase, PsycINFO, TRIP Cochrane, as well as Cochrane Skin databases. A total of 380 articles were found, of which 260 articles were removed and 87 review studies were excluded. Lastly, full texts of 33 original articles were reviewed and 14 articles that met the inclusion criteria were selected. Ten out of the 14 articles reported a high rate of alopecia recovery in women taking finasteride. Based on the results, it can be stated that 5 mg of oral finasteride per day could be an effective and safe treatment in normoandrogenic women with FPHL, especially when used in combination with other drugs, such as topical estradiol and minoxidil. We also found that topical finasteride is more effective than other topical formulas for treating hair loss.

Review
High-grade gliomas are the most common intracranial malignancies, and their current prognosis remains poor despite standard aggressive therapy. Charged particle beams have unique physical and biological properties, especially high relative biological effectiveness (RBE) of carbon ion beam might improve the clinical treatment outcomes of malignant gliomas. We systematically reviewed the safety, efficacy, and dosimetry of carbon-ion or proton radiotherapy to treat high-grade gliomas. The protocol is detailed in the online PROSPERO database, registration No. CRD42021258495. PubMed, EMBASE, Web of Science, and The Cochrane Library databases were collected for data analysis on charged particle radiotherapy for high-grade gliomas. Until July 2022, two independent reviewers extracted data based on inclusion and exclusion criteria. Eleven articles were eligible for further analysis. Overall survival rates were marginally higher in patients with the current standard of care than those receiving concurrent intensity-modulated radiotherapy plus temozolomide. The most common side effects of carbon-ion-related therapy were grade 1-2 (such as dermatitis, headache, and alopecia). Long-term toxicities (more than three to six months) usually present as radiation necrosis; however, toxicities higher than grade 3 were not observed. Similarly, dermatitis, headache, and alopecia are among the most common acute side effects of proton therapy treatment. Despite improvement in survival rates, the method of dose-escalation using proton boost is associated with severe brain necrosis which should not be clinically underestimated. Regarding dosimetry, two studies compared proton therapy and intensity-modulated radiation therapy plans. Proton therapy plans aimed to minimize dose exposure to non-target tissues while maintaining target coverage. The use of charged-particle radiotherapy seems to be effective with acceptable adverse effects when used either alone or as a boost. The tendency of survival outcome shows that carbon ion boost is seemingly superior to proton boost. The proton beam could provide good target coverage, and it seems to reduce dose exposure to contralateral organs at risk significantly. This can potentially reduce the treatment-related dose- and volume-related side effects in long-term survivors, such as neurocognitive impairment. High-quality randomized control trials should be conducted in the future. Moreover, Systemic therapeutic options that can be paired with charged particles are necessary.

Review
BACKGROUND
Woodhouse-Sakati syndrome (WSS) is a rare, autosomal recessive genetic disorder with variable clinical manifestations mainly affecting the endocrine and nervous systems. The aim of this study was to systematically review the genetic basis of WSS and report the genetic variants and clinical phenotypes associated with the disease.
METHODS
PubMed, Science Direct, Scopus, and Web of Science databases were searched from the time of inception until June 2022. Broad search terms were used to capture the literature describing all genetic variants associated with WSS. The search keywords used are "Woodhouse Sakati" along with the term "mutation" OR "gene" OR "variant" OR "polymorphism".
RESULTS
Twenty-five eligible studies were included in this study. One hundred and eighty-five patients in 97 families from 12 different countries were diagnosed with WSS. In patients from the Greater Middle East (GME) region, consanguineous marriages were common (67%). Thirteen different DCAF17 variants were associated with WSS development (including 8 identified in the GME region). The most frequent variant was a frameshift deletion variant (c.436delC, p.Ala147Hisfs*9) unique to Arabs that was reported in 11 cases from Tunisia, Kuwait, Qatar, Bahrain, and Saudi Arabia. There were no clear genotype-phenotype correlations for the different variants.
CONCLUSIONS
This systematic review highlights the molecular basis and clinical manifestations of WSS globally, including the GME region, where the disease is prevalent due to consanguinity. Additional studies are now needed to understand the genotype-phenotype correlation for different DCAF17 variants and their impact on the phenotypic heterogeneity observed in WSS patients.

Meta-Analysis
IMPORTANCE
Two recent meta-analyses reported a high prevalence of both anxiety and depression in patients with alopecia areata (AA), as well as a positive association of AA with anxiety and depression, without distinguishing between disorders and symptoms. Yet, depression and anxiety can manifest either as symptoms identified in questionnaires or as specific diagnoses defined by Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision criteria.
OBJECTIVE
To perform a large meta-analysis separating the prevalence of depressive and anxiety disorders from that of depressive and anxiety symptoms in patients with AA.
DATA SOURCES
PubMed, ScienceDirect, the Cochrane Library, Embase, and PsycINFO databases were searched from inception through August 1, 2020.
STUDY SELECTION
Studies that contained data on the prevalence of depressive or anxiety disorders or symptoms were included.
DATA EXTRACTION AND SYNTHESIS
The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines were used. Pooled prevalence was calculated with a random effects model meta-analysis that took into account between- and within-study variability. Meta-regressions were used to study the association between variations in prevalence and study characteristics.
MAIN OUTCOMES AND MEASURES
The prevalence of depressive and anxiety disorders and symptoms in patients with AA.
RESULTS
Thirty-seven articles (29 on depression and 26 on anxiety) that met the inclusion criteria were identified. By distinguishing between disorders and symptoms, the prevalence of both depressive disorders (9%) and unspecified anxiety disorders (13%) in patients with AA was shown to be greater than that in the general population. The prevalence and odds ratio (OR) of depressive disorders (prevalence, 9%; OR, 1.38) and anxiety disorders of which each category had been specifically studied (prevalence, 7%-17%; OR, 1.51-1.69) were markedly lower than that of depressive symptoms (prevalence, 37%; OR, 2.70) and anxiety symptoms (prevalence, 34%; OR, 3.07). Meta-regressions showed that variations in prevalence were mainly associated with methodological differences between studies.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, the separate analyses showed that 7% to 17% of patients with AA had depressive or anxiety disorders that require psychiatric care, including specific medication. Additionally, more than one-third of patients had symptoms that are warning signs and that need monitoring because they can develop into disorders.

Meta-Analysis
The aim of this study was to compare the efficacy and safety of treatment with Janus kinase inhibitors for alopecia areata, measured by change in Severity of Alopecia Tool (SALT) score. A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was performed using Medline, EMBASE and Cochrane library. All studies investigating the efficacy of treatments for alopecia areata were included. Primary outcomes were the proportion of patients with alopecia areata achieving 30%, 50%, 75%, 90% and 100% improvement in SALT score after treatment with a Janus kinase inhibitor. A meta-analysis was performed including all randomized controlled trials investigating Janus kinase inhibitors. A total of 37 studies matched the inclusion criteria and were included. Meta-analysis was performed based on 5 randomized studies. Regarding patients with alopecia areata defined as ≥ 50% scalp hair loss, baricitinib 4 mg once daily demonstrated the highest efficacy. However, among patients with alopecia areata defined as a SALT score ≥ 50, oral deuruxolitinib 12 mg twice daily demonstrated the highest efficacy. Deuruxolitinib and baricitinib appear to be promising drugs for the treatment of alopecia areata. However, the response depends on the dosage of the drug. More randomized trials, with identical inclusion criteria and dose and duration of treatment, are required to confirm these findings.

Review
INTRODUCTION
Scalp cooling (SC) aims to prevent chemotherapy-induced alopecia. The goal of this systematic review is to tackle ethical, legal, organizational and social issues related to SC.
METHODS
A critical appraisal of the literature was carried out using a systematic review design. MEDLINE, Embase and Web of Science databases were searched up until 2 June 2021. Studies addressing these aspects in English or Spanish were considered. Representatives of both patient associations and professional scientific societies related to the topic participated in the design of the protocol and the review of the findings.
RESULTS
A total of 17 studies were included. Articles were critically appraised using the MMAT and SANRA. Findings were organized into four categories: (1) ethical aspects focused on equal access, gender equity and doctor-patient communication supported by Patient Decision Aids (PtDAs); (2) patient perspective and acceptability; (3) professional perspective and acceptability; (4) organizational aspects focused on accessibility and feasibility.
CONCLUSION
Cancer patients' expectations when using SC need to be adjusted to reduce the potential distress associated with hair loss. PtDAs could help patients clarify their values and preferences regarding SC. Equal access to technology should be guaranteed.
PATIENT OR PUBLIC CONTRIBUTION
In this systematic review, the representatives of the patient associations (Ms. María Luz Amador Muñoz of the Spanish Association Against Cancer [AECC] and Ms. Catiana Martinez Cánovas of the Spanish Breast Cancer Federation [FECMA]) participated in the review of the study protocol, as well as in the results, discussion and conclusions, making their contributions. In the type of design of these studies (systematic reviews), it is not usual to have the direct participation of patients, but in this one, we have done so, as it is a systematic review that is part of a report of the Spanish Network of Health Technology Assessment Agencies (ETS).
