Review
PURPOSE
Aortic stenosis (AS) is a common valvular heart disease with high morbidity and mortality. Recently, the association between peak atrial longitudinal strain (PALS) and AS clinical outcomes has been identified. This systematic review evaluates the prognostic value of PALS for adverse events in AS.
METHODS
We performed a systematic literature review to identify clinical studies that evaluated Speckle-Tracking Echocardiography (STE)-derived PALS to predict adverse outcomes in patients with AS. We excluded studies that compared echocardiography to computed tomography and studies that focused on diseases other than AS.
RESULTS
We included 18 studies reporting on 2660 patients. Patients with symptomatic AS had decreased PALS when compared to patients with asymptomatic AS. Patients with AS who had adverse events had decreased PALS when compared to patients with AS with no events. Each unit increase of PALS was independently associated with decreased risk for the primary endpoint. PALS cut-off values were associated with increased risk for the primary endpoint.
CONCLUSION
This systematic review suggests PALS as an independent predictor for cardiovascular events in patients with AS and highlights the importance of evaluating LA mechanics for AS prognosis.

Review
INTRODUCTION
Some patients exhibit temporomandibular joint or muscular disorders of the masticatory system before, during, or after orthognathic surgery (OS). These are collectively referred to as temporomandibular disorders (TMDs). This systematic literature review aimed to determine the relationship between orthodontic-surgical treatment and TMDs.
METHODS
An electronic search of the PubMed database, supplemented by a manual search, was performed; the search included any studies published between 2021 (date of the last search in a systematic review of the literature on the subject) and June 2023 that evaluate the prevalence of TMDs during orthodontic-surgical treatment. The diagnosis of TMDs had to be established using the diagnostic algorithm "diagnostic criteria for temporomandibular disorders (DC/TMDs)", and the diagnosis of disc displacement had to be confirmed using magnetic resonance imaging (MRI). The data were extracted and statistically analyzed.
RESULTS
Of the 100 results, seven eligible articles were included, representing a total of 529 cases undergoing orthodontic-surgical treatment. A reduction in joint noises (64.8%), arthralgia (57 to 77%), and myalgia (73 to 100%) was found after orthodontic-surgical treatment despite the fact that a minority of patients exhibited these signs and symptoms even though they were asymptomatic before treatment. The effects of OS on disc position were objectively unpredictable. After surgery, the presence of headaches decreased without significance and the risk of their occurrence was very low (1%). The studies converged toward a reduction in the amplitudes of mouth opening and lateral/protrusion movements. Finally, after the treatment, mandibular function was improved.
CONCLUSION
Under the conditions of this study, OS seems to have a positive impact on the signs and symptoms of TMDs; however, it is not possible to predict the consequential effects on the position of the TMJ disc, whether it is initially in a normal position or displaced.

Review
(1) Background: Urinary tract infections (UTIs) are among the most frequent complications in kidney transplant (KT) recipients. Asymptomatic bacteriuria (ASB) may be a risk factor for UTIs and graft rejection. We aimed to evaluate available evidence regarding the benefit of screening and treatment of ASB within the first year after KT. (2) Evidence acquisition: A systematic literature search was conducted in MEDLINE, the Cochrane Library CENTRAL and Embase. Inclusion criteria were manuscripts in English addressing the management of ASB after KT. The PICO questions concerned Patients (adults receiving a KT), Intervention (screening, diagnosis and treatment of ASB), Control (screening and no antibiotic treatment) and Outcome (UTIs, sepsis, kidney failure and death). (3) Evidence synthesis: The systematic review identified 151 studies, and 16 full-text articles were evaluated. Seven were excluded because they did not evaluate the effect of treatment of ASB. There was no evidence for a higher incidence of lower UTIs, acute pyelonephritis, graft loss, or mortality in patients not treated with antibiotics for ASB. Analysis of comparative non-randomized and observational studies did not provide supplementary evidence to guide clinical recommendations. We believe this lack of evidence is due to confounding risk factors that are not being considered in the stratification of study patients.

Review
OBJECTIVE
Race-based disparities in health care have been related to a myriad of prevailing factors among minorities in the United States. This study aims to study the race-based differences in the outcomes of carotid endarterectomy (CEA).
METHODS
The PROSPERO database registered the review protocol (CRD42023428253). A systematic English literature review was performed using literature databases PubMed and Scopus from inception till June 2023. The review was designed on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and included studies reporting mortality, stroke, or composite outcome of mortality and stroke after CEA for carotid artery disease, regardless of any degree of stenosis including both symptomatic and asymptomatic patients. The risk of bias was evaluated utilizing the Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool. A pooled odds ratio (OR) for the overall mortality was computed, and a P value of < .05 was designated as statistically significant. Interstudy heterogeneity was evaluated by Q-metric and quantified using Higgins I statistics.
RESULTS
Twelve studies were identified which included a total of 574,055 patients who underwent CEA from 1998 to 2022. Eleven of 12 studies reported 30-day mortality as an outcome for patients undergoing CEA in which 524,708 patients (92.5%) were White and 42,797 (7.5%) were non-White. The overall pooled OR indicated a statistical significance in 30-day mortality between White and non-White patients undergoing CEA (OR, 1.73; 95% confidence interval [CI], 1.37-2.18; P = .011) with substantial heterogeneity (I = 56.3%). Eleven of 12 studies reported stroke as an outcome for patients undergoing CEA in which 524,708 patients (92.5%) were White and 42,801 (7.5%) were non-White. The overall pooled OR indicated no statistical significance in stroke between White and non-White patients undergoing CEA (OR, 1.46; 95% CI, 1.28-1.65; P = .111) with moderate heterogeneity (I = 35.9%). Five of 12 studies reported composite mortality or stroke as an outcome for patients undergoing CEA. The overall pooled OR indicated no statistical significance in composite mortality or stroke between White and non-White patients undergoing CEA (OR, 1.40; 95% CI, 1.24-1.59; P = .467) with no heterogeneity (I = 0.0%).
CONCLUSIONS
Non-White patients have a relatively higher risk of mortality; however, no significant difference was observed between the racial groups in terms of stroke or a composite outcome of mortality or stroke. The odds of mortality in non-White patients have been persistent throughout recent studies.

Asymptomatic infections with Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis among women in low- and middle-income countries: A systematic review and meta-analysis.
Syndromic management of sexually transmitted infections (STIs) is common in settings with limited access to diagnostic testing. However, this approach does not capture asymptomatic STIs. Untreated asymptomatic infections may result in serious complications and sequelae in women. We aimed to estimate the proportion and the prevalence of asymptomatic Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) infections among women in low- and middle-income countries. We searched Medline, Scopus, and Web of Science for articles published between 2000 and 2022. We used random effect models to compute the proportion and prevalence estimates and performed sub-group analysis. We evaluated the quality of each article using the Appraisal tool for Cross-Sectional Studies and performed sensitivity analyses. This study was registered with PROSPERO, CRD42022286673. Forty-eight eligible studies were included. The proportion of asymptomatic CT, NG, and TV infections were: 60.7% [95% Confidence Interval (CI): 50.4; 70.5], 53.3% [37.1; 69.1], and 56.9% [44.6; 68.9], respectively. The proportion of women with asymptomatic infections was the highest in Africa for the three pathogens. The pooled prevalence of asymptomatic CT, NG, and TV infection was 4.70 per 100 women [95%CI: 3.39; 6.20], 3.11 [1.34; 5.54], and 5.98 [3.46; 9.12], respectively. More than half of the women infected by CT, NG, or TV were asymptomatic. To avoid undiagnosed and untreated asymptomatic infections leading to complications, alternative approaches to syndromic management urgently need to be considered.

Scandinavian Journal of Gastroenterology May 2024Adenoma detection rate (ADR) is higher after a positive fecal immunochemical test (FIT) compared to direct screening colonoscopy. (Review)
Review
BACKGROUND
Adenoma detection rate (ADR) is higher after a positive fecal immunochemical test (FIT) compared to direct screening colonoscopy.
OBJECTIVE
This meta-analysis evaluated how ADR, the rates of advanced adenoma detection (AADR), colorectal cancer detection (CDR), and sessile serrated lesion detection (SSLDR) are affected by different FIT positivity thresholds.
METHODS
We searched MEDLINE, EMBASE, CINAHL, and EBM Reviews databases for studies reporting ADR, AADR, CDR, and SSLDR according to different FIT cut-off values in asymptomatic average-risk individuals aged 50-74 years old. Data were stratified according to sex, age, time to colonoscopy, publication year, continent, and FIT kit type. Study quality, heterogeneity, and publication bias were assessed.
RESULTS
Overall, 4280 articles were retrieved and fifty-eight studies were included (277,661 FIT-positive colonoscopies; mean cecal intubation 96.3%; mean age 60.8 years; male 52.1%). Mean ADR was 56.1% (95% CI 53.4 - 58.7%), while mean AADR, CDR, and SSLDR were 27.2% (95% CI 24.4 - 30.1%), 5.3% (95% CI 4.7 - 6.0%), and 3.0% (95% CI 1.7 - 4.6%), respectively. For each 20 μg Hb/g increase in FIT cut-off level, ADR increased by 1.54% (95% CI 0.52 - 2.56%, < 0.01), AADR by 3.90% (95% CI 2.76 - 5.05%, < 0.01) and CDR by 1.46% (95% CI 0.66 - 2.24%, < 0.01). Many detection rates were greater amongst males and Europeans.
CONCLUSIONS
ADRs in FIT-positive colonoscopies are influenced by the adopted FIT positivity threshold, and identified targets, importantly, proved to be higher than most current societal recommendations.

BACKGROUND
Subclinical thyroid diseases are often the subject of debate concerning their clinical significance, the appropriateness of diagnostic testing, and possible treatment. This systematic review addresses the variation in international guidelines for subclinical hyperthyroidism, focusing on diagnostic workup, treatment, and follow-up recommendations.
METHODS
Following the PRISMA guidelines, we searched PubMed, Embase, and guideline-specific databases and included clinical practice guidelines with recommendations on subclinical hyperthyroidism. Guideline recommendations were extracted, and quality assessment was performed using selected questions of the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument.
RESULTS
Of the 2624 records screened, 22 guidelines were included, which were published between 2007 and 2021. Guideline quality was generally intermediate to low. Diagnostic approaches differed substantially, particularly in the extent of recommended testing. Treatment initiation depended on TSH levels, age, and comorbidities, but the level of detail regarding defining precise comorbidities varied. Recommendations for monitoring intervals for follow-up ranged from 3 to 12 months.
CONCLUSION
This review underscores the existing variability in (inter)national guidelines concerning subclinical hyperthyroidism. There isa need for clear recommendations in guidelines considering diagnostic workup, treatment, and follow-up of subclinical hyperthyroidism. In order to establish this, future research should focus on determining clear and evidence-based intervention thresholds.

Review
INTRODUCTION
Uterine fibroids are the commonest benign tumors of the reproductive tract in women of childbearing age. They are usually asymptomatic but can cause menorrhagia. Treatments include myomectomy and uterine artery embolization (UAE). The latter is a relatively new procedure, therefore of special interest.
OBJECTIVES
We conducted a systematic review and meta-analysis of all published studies to provide a comprehensive outlook on the effectiveness of UAE by comparing its outcomes to those of myomectomy. Electronic databases (PubMed and Cochrane Central) were systematically searched from January 2000 to March 2022 for published randomized control trials, observational studies, and meta-analyses that compared UAE to myomectomy for at least one of the pre-specified outcomes, namely re-intervention rates, length of hospital stay, and complications.
METHODS
We shortlisted nine studies for the final analysis. For continuous outcomes, results from random-effects meta-analysis were presented as mean differences (MDs) and corresponding 95% confidence intervals (CIs). Risk ratios (RRs) for dichotomous outcomes were pooled using a random-effects model.
RESULTS
The final analysis consisted of nine studies. Factors like re-intervention, hospitalization, and complications, each with its unique follow-up duration were assessed. Pooled analysis demonstrated significant results for greater re-intervention rates with UAE as compared to myomectomy (RR: 2.16, 95% CI: (1.27-3.66), value 0.004, heterogeneity = 85%). UAE holds a greater but statistically insignificant risk for major complications (RR: 0.62, 95% CI: (0.29-1.33), value 0.22, heterogeneity = 0%) and myomectomy shows a statistically insignificant greater risk for minor complications (RR: 1.72, 95% CI: (0.92-3.22), value 0.09, heterogeneity = 0%). UAE had a shorter but statistically insignificant duration of hospital stay (MD: -1.12, 95% CI: (-2.50 to 0.27), value 0.11, heterogeneity = 96%) (value for subgroup differences = 0.005).
CONCLUSION
Our meta-analysis of approximately 196,595 patients demonstrates that myomectomy results in a significant reduction in re-intervention rate compared to UAE.

Meta-Analysis Review
Canine enteric coronavirus (CeCoV) is a globally distributed enteric pathogen that causes significant harm to canines. The objective of this systematic review was to examine the global dissemination of CeCoV and assess the potential for infected canines to be exposed to various CeCoV genotypes and subtypes. With an aggregated prevalence of 18.8%, the study predicted regional variations, indicating that CeCoV is an exceptionally prevalent disease. The increased likelihood that infected canines will be asymptomatic is a significant cause for concern, as undetected cases of CeCoV infection could persist and spread the disease. This underscores the significance of ongoing surveillance of CeCoV in order to avert its transmission. Nevertheless, further investigation is necessary in order to ascertain the moderators that significantly impact the prevalence and distribution of distinct subtypes and genotypes of CeCoV. Hence, it is imperative to undertake randomized clinical trials in order to acquire a more accurate understanding of the variables that influence the prevalence of CeCoV. By conducting ongoing surveillance, regional variations in the prevalence of CeCoV in canines can be accounted for, thereby enhancing our comprehension of the illness and ultimately impeding its transmission.

CONTEXT
Parathyroidectomy is recommended for curing primary hyperparathyroidism (PHPT), although uncertainty remains regarding the extent of fracture risk reduction following surgery.
OBJECTIVE
To compare fracture risk and bone mineral density (BMD) changes in patients with PHPT undergoing parathyroidectomy (PTX) versus observation (OBS).
DATA SOURCES
We systematically searched PubMed, Embase, and the Cochrane Library until September 2022, including randomized controlled trials (RCTs) and cohort studies, and reviewed citations from previous reviews.
STUDY SELECTION
Among 1,260 initial records, 48 eligible articles from 35 studies (5 RCTs; 30 cohorts) included PHPT patients receiving PTX or OBS interventions with reported fracture events at any site, including the hip, spine, or forearm, and/or BMD changes at each location.
DATA EXTRACTION
Following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines by two independent reviewers.
DATA SYNTHESIS
In 238,188 PHPT patients (PTX: 73,778 vs. OBS: 164,410), parathyroidectomy significantly reduced fractures at any site (RR, 0.80; 95%CI, 0.74-0.86) compared to observation. In 237,217 patients (PTX: 73,458 vs. OBS: 163,759), the risk of hip fractures decreased (RR, 0.63; 95%CI, 0.52-0.76). No reduction in forearm and vertebral fractures was observed in 3,574 and 3,795 patients, respectively. The annual percentage BMD changes from baseline were higher in the PTX group: femoral neck, 1.91% (95%CI, 1.14-2.68); hip, 1.75% (95%CI, 0.58-2.92); radius, 1.75% (95%CI, 0.31-3.18); spine, 2.13% (95%CI, 1.16-3.10).
CONCLUSIONS
Parathyroidectomy significantly reduced overall and hip fracture risks in PHPT patients. Despite minimal BMD increase, the substantial decrease in fracture risk suggests additional benefits of PTX beyond mineral content enhancement.
