Despite the worldwide increase in frozen embryo transfer, the search for the best protocol to prime endometrium continues. Well-designed trials comparing various frozen embryo transfer protocols in terms of live birth rates, maternal, obstetric and neonatal outcome are urgently required. Currently, low-quality evidence indicates that, natural cycle, either true natural cycle or modified natural cycle, is superior to hormone replacement treatment protocol. Regarding warmed blastocyst transfer and frozen embryo transfer timing, the evidence suggests the 6 day of progesterone start, LH surge+6 day and hCG+7 day in hormone replacement treatment, true natural cycle and modified natural cycle protocols, respectively. Time corrections, due to inter-personal differences in the window of implantation or day of vitrification (day 5 or 6), should be explored further. Recently available evidence clearly indicates that, in hormone replacement treatment and natural cycles, there might be marked inter-personal variation in serum progesterone levels with an impact on reproductive outcomes, despite the use of the same dose and route of progesterone administration. The place of progesterone rescue protocols in patients with low serum progesterone levels one day prior to warmed blastocyst transfer in hormone replacement treatment and natural cycles is likely to be intensively explored in near future.

Introduction: the main treatment for people with autism spectrum disorder (ASD) corresponds to cognitive behavioral therapy in conjunction with pharmacotherapy. Together they seek to attenuate the behavioral symptoms of these patients, as well as to increase their social functionality. However, other strategies have become popular to achieve the same goal of classical treatment. Particularly, nutritional interventions are positioned above others, and it is necessary to investigate their effectiveness, considering that children with ASD present a marked food selectivity, as well as gastrointestinal alterations. Objective: to evaluate the effectiveness of nutritional interventions in the behavioral symptomatology of infants with ASD. Methods: a systematic search was carried out in the Scopus and PubMed databases, in Spanish and English. The filters of clinical studies and original articles were used, choosing only nutritional interventions in children under 19 years of age and who had had at least 4 weeks of intervention. Results: evidence was found on gluten- and casein-free diets, ketogenic diet, omega-3 supplementation, prebiotics/probiotics, and vitamins/minerals presenting positive results in most of the articles analyzed; however, the heterogeneity presented requires a greater body of evidence to promote its use. Conclusion: the five types of nutritional interventions evaluated show varied evidence that does not allow defining the degree of effectiveness between one or the other in terms of behavioral improvements in the population with ASD.

The modified Dietary Approaches to Stop Hypertension (DASH) diet was a potentially effective treatment for pre-hypertensive and hypertensive patients. The evidence for the effect of the modified DASH diet on blood pressure reduction was inconsistent. The study was designed to assess the effects of the modified DASH diet on blood pressure (BP) in hypertensive and pre-hypertensive adults. We searched Medline, Embase, CENTRAL, CNKI, VIP, Wanfang Data, SINOMED, Google Scholar, the World Health Organization's International Clinical Trials Registry Platform, and Clinicaltrials.gov from inception to July 1st, 2021. Randomized controlled trials (RCTs) assessing the effects of the modified DASH diet on systolic and diastolic BP, cardiovascular risk factors (body weight, body mass index, waist circumference, fasting glucose, blood lipids), cardiovascular events, and all-cause mortality were included. Statistical analysis was performed using Stata software. Risk of bias was assessed with the Cochrane tool and quality of evidence with GRADE. A total of 10 RCTs were included. Compared with control diet, the modified DASH diet could reduce mean systolic (-3.26 mmHg; 95% confidence interval -5.58, -0.94 mmHg; = 0.006) and diastolic (-2.07 mmHg; 95% confidence interval -3.68, -0.46 mmHg; = 0.01) BP. Compared with the controlling diet, the modified DASH diet could reduce systolic BP to a greater extent in trials with a mean baseline BP ≥ 140/90 mmHg compared with <140/90 mmHg. Diastolic BP reduction was greater when the mean body mass index was ≥30 kg/m2 than <30 kg/m. Diastolic BP reduction was more marked in trials with a follow-up time of >8 weeks compared with ≤8 weeks. The modified DASH diet could affect mean waist circumference (difference: 1.57 cm; 95% confidence interval -2.98, -0.15) and triglyceride concentration (difference: 1.04 mol/L; 95% confidence interval -1.47, -0.60). The modified DASH diet can reduce BP, waist circumference, and triglyceride concentration in hypertension patients. A higher baseline BP is associated with more marked systolic and diastolic BP reduction. PROSPERO registration number: CRD42020190860.

Review
The aim of this review was to describe the changes in the microbiota of patients with Behçet's disease (BD) and the mechanisms involved in the relationship between the microbiome and immunity in BD. A systematic search for relevant articles was made on PubMed and the Cochrane Library database using the following terms: "microbiota AND Behçet's disease" or "microbiome AND Behçet's disease". Sixteen articles were included in a qualitative synthesis. This systematic review on the microbiome and Behçet's disease underlines the presence of gut dysbiosis in BD patients. This dysbiosis is marked by (i) a decrease in butyrate-producing bacteria, which could affect T cell differentiation and epigenetic regulation of immune-related genes, (ii) a modification of tryptophan-metabolising bacteria, which could be linked to dysregulated IL-22 secretion, and (iii) a decrease in bacteria known to have anti-inflammatory properties. Regarding oral microbiota, this review underlines the possible role of Streptococcus sanguinis through molecular mimicry and NETosis. Clinical studies of BD have shown that (i) need for dentistry is associated with a more severe course in BD, and (ii) antibiotic-supplemented mouthwash reduces pain and ulcers. Fecal transplantation of BD patients' microbiota into mouse models led to decreased SCFA production, neutrophil activation, and Th1/Th17 responses.Recipient mice showed exacerbated experimental autoimmune uveitis (EAU) and experimental autoimmune encephalomyelitis (EAE). In Herpes Virus Simplex-1 (HSV-1) infected mice mimicking BD, administration of butyrateproducing bacteria improved symptoms and immune variables. The microbiome may thus be involved in BD through immunity regulation and epigenetic modifications.

Review
Papilliferous keratoameloblastoma (PKA) is a rare entity, and not much is known about its clinicodemographic features or biological nature. This review aimed to provide clarity regarding the characterisation of the demographic, clinical, radiological and histopathological features of PKA. Case reports of PKA were identified through a systematic search across multiple databases. The search yielded a total of 10 cases, half of which were of Indian origin. All the cases invariably occurred in the mandibular posterior region and involved the right side; only one case primarily involved the left side of the mandible. PKA should be considered a variant of the conventional ameloblastoma that is towards the more aggressive end of the spectrum. It tends to occur in older individuals (in their fifth decade or older), with a marked propensity to occur in the right mandibular posterior region. Surgical resection with diligent follow-up is warranted in the treatment of PKA.

Meta-Analysis Review
The current evidence on the association of leukocyte telomere length (LTL) with age-related structural and cognitive changes in the brain is mixed. Herein conforming to PRISMA 2020 guidelines, we performed a systematic review and meta-analysis using data from 27 observational studies in non-demented individuals. We used effect size and p-value based meta-analysis methods considering marked heterogeneity among studies. We found that the longer LTL was associated with higher brain volume (β = 0.43, 95%CI: 0.36-0.50%, p = 0.008, N = 1102) and with higher global cognition (β = 0.01; 95%CI: 0.00-0.02, p = 0.03, N = 19609) by effect size based meta-analysis and with brain volume, hippocampal volume, global cognition, cognitive domains of attention/speed as well as executive functions by p-value based meta-analysis. No significant association of LTL with brain white matter hyperintensities was detected. Furthermore, the evidence strongly suggests a subgroup-specific canonical effect of telomeres, notably in older individuals and females. In conclusion, we provide meta-analytic evidence on the beneficial effect of telomeres on brain structure as well as cognition and advocate for a beneficial subgroup-specific effect that warrants further attention.

Review
Since the onset of COVID-19, studies suggest a significant increase in online gambling, potentially facilitated by increased time at home, social isolation and boredom. This study aimed to address what is known about the impact of the pandemic on gambling behaviour by conducting a mapping review. A systematic literature search was conducted using four online databases. Additional studies were identified using reference lists. Relevant studies were quality scored and their findings synthesised in terms of overall changes at the population level and potentially vulnerable groups. The weight of evidence from 35 relevant reports across 12 countries indicated reductions of gambling during the pandemic at the level of the general population. However, marked increases in gambling amongst vulnerable sub-populations including amongst young adults and people with pre-existing at-risk gambling were also noted. The impact of COVID-19 on gambling is highly contingent on context. If policy makers examine only population level data, this could overlook profound negative effects identified in those with at-risk gambling, gambling disorder, and amongst young adults.

PURPOSE
Bariatric surgery is an increasingly common treatment for obesity and related comorbidities. This meta-analysis aimed to compare the outcomes of bariatric surgery and medical treatment (MT).
MATERIALS AND METHODS
A systematic search of articles published from January 2013 to May 2023 identified 20 studies. The treatment arms included Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), gastric banding, and MT. The assessed outcomes included body weight loss, diabetes mellitus (DM) remission, changes in dyslipidemia and hypertension markers, and adverse events.
RESULTS
Bariatric surgery resulted in significantly better short- and long-term weight loss than MT, with RYGB and SG showing the most substantial reduction. The DM remission rates were notably higher in the surgery group, with marked improvements in hemoglobin A1c and fasting glucose levels. Improvements in dyslipidemia were inconclusive, whereas hypertension showed modest improvements, particularly with RYGB. Complication rates varied, with RYGB reporting higher rates of early complications, and SG reporting increased rates of late complications. The perioperative reoperation rates were low across all surgical treatments. Specific adverse events, such as intestinal obstruction and anastomosis site problems, were more common in the RYGB group, whereas reflux symptoms were more common in the SG group.
CONCLUSION
Bariatric surgery, especially RYGB and SG, provided superior weight loss and DM remission outcomes compared to MT, although with varied complication profiles. These findings underscore the need for careful patient selection and postoperative management in bariatric surgery. Future studies should aim to refine these processes to improve patient outcomes.

Review
In recent times, novel oral anticoagulants (NOACs)/direct oral anticoagulants (DOACs) have emerged as an alternative to the traditionally used Vitamin K oral antagonists (VKA) like warfarin for the treatment of atrial fibrillation (AF). This systematic review and meta-analysis aims to evaluate the efficacy and safety of NOACs in patients with AF and, thus, the related thromboembolic risks and sequelae. Of the 131 published articles we examined, 11 were included in an in-depth systematic review. The articles we reviewed were from the past ten years, from 2013 onward. The analysis derived the efficacy and safety of NOACs in patients with AF and also included different patients' baseline characteristics and subgroups. This systematic review reiterates previous research findings of superior efficacy and safety of the use of NOACs in the AF population and also illuminates certain head-to-head comparisons of individual NOACs with warfarin. It digressed into subgroups of patients with different baseline characteristics to provide evidence and support the existing guidelines for the use of NOACs in the treatment of AF. Overall, there is marked efficacy and safety of NOACs in patients with AF, be they elderly or Asian, with decreased renal function, or with other comorbidities. Adherence to NOACs was also satisfactory. Despite such a review, there needs to be more research on vast subgroups and also on reversal antidotes like andexanet alfa and idarucizumab, as well as more head-to-head analysis between NOACs over a long duration of study, which would provide more answers and pinpoint reasons as to the differences that exist between demographics and subgroups in the usage of NOACs.

Meta-Analysis
INTRODUCTION
It is unclear whether hydrodilatation is beneficial in the management of frozen shoulder compared with other common conservative management modalities. This systematic review evaluates the efficacy of hydrodilatation for the management of frozen shoulder.
SOURCES OF DATA
A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. An extensive search of PubMed, Embase, Scopus, Cochrane Central, Web of Science and CINAHL databases using multiple keyword combinations of 'shoulder', 'rotator', 'adhesive capsulitis', 'hydrodilatat*', 'distension' since inception of the databases to June 2023 was implemented.
AREAS OF AGREEMENT
Hydrodilatation leads to at least transient more marked improvements in shoulder disability and passive external rotation compared with intra-articular corticosteroid injections.
AREAS OF CONTROVERSY
Hydrodilatation improves passive external rotation in the longer term. Moreover, hydrodilatation may be a preferable option over manipulation under anaesthesia, given its lower cost and better patient convenience.
GROWING POINTS
Intensive mobilization after hydrodilatation is a promising adjuvant treatment option for patients suffering from a frozen shoulder.
AREAS TIMELY FOR DEVELOPING RESEARCH
Although current evidence suggests that hydrodilatation provides a transient improvement in disability in patients with frozen shoulder, its clinical relevance remains unclear. Further research is necessary to establish its role in the management of the condition.
