Ablation and laparoscopic adrenalectomy: Balancing efficacy and safety in the treatment of benign adrenal gland tumors: A systematic review and meta-analysis.

Background: Aldosterone-producing adenomas cause hypertension in 5-10 % of cases. Laparoscopic adrenalectomy is the gold standard treatment for early-stage adrenal gland tumors, but minimally invasive procedures, such as ablative techniques can also be applied. Therefore, we aimed to compare laparoscopic adrenalectomy and ablation techniques in terms of efficacy and safety in the treatment of benign adrenal gland tumors. Materials and methods: We conducted a systematic search in five databases and included studies comparing the efficacy and safety of ablation techniques and laparoscopic adrenalectomy. We calculated odds ratios (ORs) for eligible studies with binary outcomes, and mean differences (MD) with 95 % confidence intervals (CI) for continuous outcomes. Results: Five studies focusing on aldosterone-producing adenomas were included in our review. A total of 119 patients at 14 centers underwent ablation, and 161 patients had laparoscopic adrenalectomy. The complication rates (OR: 0.98, CI: 0.35-2.69) were similar in both groups, but among complications, hypertensive crisis (OR: 8.13; CI: 1.14-58.11) was more frequent in the ablative group, and even the success rate of interventions - the resolution of hypertension (OR: 0.30, CI: 0.16-0.56) - was lower in this group. On the other hand, the advantage of ablation was shorter intervention time (MD: 75.64 min; CI: 6.33-144.95), shorter hospital stay (MD: 1.6 days; CI: 0.88-2.31), and less perioperative blood loss (MD: 43.55 ml; CI: 12.07-75.04) compared to laparoscopy. Conclusion: Laparoscopic adrenalectomy is still the best therapeutic approach, but ablation can be an appropriate alternative option for the treatment of aldosterone-producing adrenal gland tumors.

MUC17 is a potential new prognostic biomarker and promotes pancreatic cancer progression in obstructive jaundice.

Our working group has previously shown that bile acids (BAs) accelerate carcinogenic processes in pancreatic cancer (PC) in which mucin 4 (MUC4) expression has a central role. However, the role of other mucins in PC are less clear, especially in bile-induced cancer progression. The study aim was to investigate expression of MUC17 in BAs- or human serum-treated pancreatic ductal adenocarcinoma (PDAC) cell lines and use different assays with RNA silencing/overexpression to study the role of MUC17 in cancer progression. Protein expression of MUC17 was evaluated in 55 human pancreatic samples by immunohistochemistry, and Kaplan-Meier survival analysis was used to compare survival curves. Expression of MUC17 increased in PDAC patients, especially in obstructive jaundice (OJ) and the elevated MUC17 expression associated with poorer overall survival (10.66±1.99 vs. 15.05±2.03 months; Log rank: 0.0497). Treatment of Capan-1 and AsPC-1 cells with BAs or with human serum obtained from PDAC + OJ patients enhanced the expression of MUC17, as well as the proliferative potential of the cells, whereas knockdown of MUC17 alone or in combination with MUC4 decreased BAs-induced carcinogenic processes. Our results demonstrated that MUC17 has a central role in bile-induced PC progression, and in addition to MUC4, this isoform also can be used as a novel prognostic biomarker.

Diagnostic Accuracy of Artificial Intelligence for Approximal Caries on Bitewing Radiographs: A Systematic Review and Meta-analysis.

OBJECTIVES: This systematic review and meta-analysis aimed to investigate the diagnostic accuracy of Artificial Intelligence (AI) for approximal carious lesions on bitewing radiographs. METHODS: This study included randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) reporting on the diagnostic accuracy of AI for approximal carious lesions on bitewing radiographs. The risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. A systematic search was conducted on November 4, 2023, in PubMed, Cochrane, and Embase databases and an updated search was performed on August 28, 2024. The primary outcomes assessed were sensitivity, specificity, and overall accuracy. Sensitivity and specificity were pooled using a bivariate model. RESULTS: Of the 2,442 studies identified, 21 met the inclusion criteria. The pooled sensitivity and specificity of AI were 0.94 (confidence interval (CI): ± 0.78-0.99) and 0.91 (CI: ± 0.84-0.95), respectively. The positive predictive value (PPV) ranged from 0.15 to 0.87, indicating a moderate capacity for identifying true positives among decayed teeth. The negative predictive value (NPV) ranged from 0.79 to 1.00, demonstrating a high ability to exclude healthy teeth. The diagnostic odds ratio was high, indicating strong overall diagnostic performance. CONCLUSIONS: AI models demonstrate clinically acceptable diagnostic accuracy for approximal caries on bitewing radiographs. Although AI can be valuable for preliminary screening, positive findings should be verified by dental experts to prevent unnecessary treatments and ensure timely diagnosis. AI models are highly reliable in excluding healthy approximal surfaces. CLINICAL SIGNIFICANCE: AI can assist dentists in detecting approximal caries on bitewing radiographs. However, expert supervision is required to prevent iatrogenic damage and ensure timely diagnosis.

Restoring CFTR function with Orkambi decreases the severity of alcohol-induced acute pancreatitis.

Heavy alcohol intake is one of the most common causes of acute pancreatitis (AP). We have previously shown that ethanol (EtOH) decreases the expression and activity of the cystic fibrosis transmembrane conductance regulator (CFTR), which plays a key role in alcohol-induced AP development. The prescription drug, Orkambi (a combination of ivacaftor and lumacaftor) can correct impaired CFTR function and expression in cystic fibrosis (CF) patients. Thus, the present study aimed to investigate whether Orkambi can mitigate alcohol-induced AP. Intact guinea-pig pancreatic ducts were pre-treated with different concentrations of ethanol (EtOH; 30, 50 and 100 mm) for 12 h alone or in combination with ivacaftor (VX770) and/or lumacaftor (VX-809), and CFTR expression and activity were evaluated by immunostaining and by the patch clamp technique, respectively. Alcoholic AP was induced in Orkambi-treated guinea-pigs, and standard laboratory and histological parameters were measured. Ivacaftor and lumacaftor alone or in combination dose-dependently restored the apical expression and activity of CFTR after EtOH treatment in vitro. Oral administration of Orkambi reduced the severity of alcohol-induced AP and restored impaired CFTR activity and expression. Orkambi is able to restore the CFTR defect caused by EtOH and decreases the severity of alcohol-induced pancreatitis. This is the first in vivo pre-clinical evidence of Orkambi efficacy in the treatment of alcohol-induced AP. KEY POINTS: Acute pancreatitis is one of the leading causes of hospital admission among gastrointestinal diseases in which the lack of a specific drug therapy plays a crucial role. The cystic fibrosis transmembrane conductance regulator (CFTR) plays an essential role in pancreatic ductal HCO3 - secretion; inappropriate CFTR function, as seen in heavy alcohol consumption, increases the risk of pancreatitis development. CFTR modulators are able to prevent the inhibitory effect of ethanol and reduce pancreatic ductal injury and the severity of alcohol-induced pancreatitis. CFTR modulators present a novel option in the pharmacotherapy of alcohol-induced pancreatitis by enhancing pancreatic functions or preventing recurrence.

Head-to-head comparison of influenza vaccines in children: a systematic review and meta-analysis.

Although vaccination is considered the most effective weapon against influenza, coverage rates, national vaccination policies, and funding vary largely around the globe. Despite their huge potential for achieving herd immunity, child-focused national vaccination strategies that favor pain-free nasal vaccines are uncommon. CENTRAL, Embase, and MEDLINE were last searched on November 13, 2023. Active-controlled randomized controlled trials comparing the live-attenuated intranasal vaccine with the inactivated intramuscular influenza vaccine in children were included. Event rates of laboratory-confirmed influenza virus infection, all-cause mortality, hospitalization, serious adverse events, adverse events, and financial outcomes were extracted based on the PRISMA 2020 Guideline. PROSPERO: CRD42021285412. Pooled odds ratios (ORs) with 95% confidence intervals (CI) were calculated using the random-effects model when at least three comparable outcomes were available. We found no significant difference between quadrivalent live-attenuated intranasal and trivalent inactivated intramuscular (OR = 1.48; 95% CI 0.49-4.45) or between trivalent live-attenuated intranasal and inactivated intramuscular vaccines (OR = 0.77, CI = 0.44-1.34) regarding their efficacy. However, the subgroup analysis of large, multi-center trials indicated that the trivalent live attenuated intranasal influenza vaccine was superior to the trivalent inactivated intramuscular influenza vaccine (12,154 people, OR = 0.50, CI = 0.28-0.88). Only 23 "vaccine-related serious adverse events" were recorded among 17 833 individuals, with no significant difference between methods. The widespread initiation of pediatric national flu vaccination programs prioritizing the live-attenuated intranasal influenza vaccine would be beneficial. Multi-continent, high-quality studies that include children younger than two years old and those living in subtropical and tropical regions are needed to further enhance our understanding.

Umbilical cord management in newborn resuscitation: a systematic review and meta-analysis.

BACKGROUND: Evidence supporting the benefits of delayed cord clamping is increasing; however, there is no clear recommendation on cord management during newborn resuscitation. This study aimed to investigate the effects of resuscitation initiated with an intact umbilical cord, hypothesizing it is a safe stabilization procedure that improves neonatal outcomes. METHODS: Systematic search was conducted in MEDLINE, Embase, CENTRAL, and Web of Science from inception to March 1, 2024. Eligible articles compared neonatal outcomes in newborns receiving initial stabilization steps before and after cord clamping. RESULTS: Twelve studies met our inclusion criteria, with six RCTs included in the quantitative analysis. No statistically significant differences were found in delivery room parameters, in-hospital mortality, or neonatal outcomes between the examined groups. However, intact cord resuscitation group showed higher SpO2 at 5 min after birth compared to cord clamping prior to resuscitation group (MD 6.67%, 95% CI [-1.16%, 14.50%]). There were no significant differences in early complications of prematurity (NEC ≥ stage 2: RR 2.05, 95% CI [0.34, 12.30], IVH: RR 1.25, 95% CI [0.77, 2.00]). CONCLUSION: Intact cord management during resuscitation appears to be a safe intervention; its effect on early complications of prematurity remains unclear. Further high-quality RCTs with larger patient numbers are urgently needed. IMPACT: Initiating resuscitation with an intact umbilical cord appears to be a safe intervention for newborns. No statistically significant differences were found in delivery room parameters, in-hospital mortality, and neonatal outcomes between the examined groups. The utilization of specialized resuscitation trolleys appears to be promising to reduce the risk of intraventricular hemorrhage in preterm infants. Further high-quality RCTs with larger sample sizes are urgently needed to refine recommendations.

Individualized Pain Treatment in Chronic Pancreatitis (INPAIN): An International, Multicenter, Investigator-initiated, Prospective, Cohort Study.

INTRODUCTION: Pain is the foremost complication of chronic pancreatitis (CP), affecting about 70% of patients. However, the pathophysiological understanding and management of CP-related pain is complex, likely as patients have diverse "pain phenotypes" responding differently to treatment. This study aims to develop a bedside test panel to identify distinct pain phenotypes, investigate the temporal evolution, and determine whether they can be used to predict treatment response. METHOD: The INPAIN study is an international, multi-center, observational, longitudinal cohort study comprised of 4 sub-studies. The studies will prospectively enroll 400 CP patients (50 without pain and 350 with pain) and 50 control subjects, conducting biannual observations for four years. The test panel is comprised of comprehensive subjective and objective assessment parameters. Statistical analysis strategies differ across the sub-studies. A model to predict treatment efficacy will be developed using various machine learning techniques, including an artificial intelligence approach, with internal cross-validation. Trajectories in pain parameters will be characterized by graphical analysis and mixed effect models. DISCUSSION: The INPAIN study aims to comprehensively understand pain in CP through a test panel developed for routine clinical use. This tool has the potential to personalize treatments, improve clinical practice, enhance patient care, improve quality of life, and minimize treatment side effects.

Color Comparison Between Intraoral Scanner and Spectrophotometer Shade Matching: A Systematic Review and Meta-Analysis.

OBJECTIVE: This systematic review and meta-analysis compared the accuracy of intraoral scanners and spectrophotometers in determining tooth shade. MATERIALS AND METHODS: An electronic search of five databases (PubMed, Scopus, Embase, Web of Science, CENTRAL) was conducted on October 19, 2023. A total of 163 studies were identified from the databases, of which 23 articles were eligible for inclusion. In vivo and in vitro quasi-experimental studies were included. After data extraction, a quantitative analysis was performed to determine the accuracy of the intraoral scanner in subgroups using four outcomes: trueness and precision with different measurement locations. A random-effects model was used to pool effect sizes. The pooled proportion with a 95% confidence interval (CI) was used for the effect size measure. RESULTS: Eleven articles were included in the meta-analysis. Trueness with the intraoral scanner was between 0.28 (CI: 0.09-0.60) and 0.38 (CI: 0.24-0.53). Repeatability was between 0.81 (CI: 0.64-0.91) and 0.85 (CI: 0.74-0.92). Trueness showed low, and precision had moderate certainty of evidence. CONCLUSION: The trueness of shade matching with intraoral scanners is low compared to spectrophotometers, although the precision is considered high and is similar to spectrophotometers. CLINICAL SIGNIFICANCE: Shade determination with intraoral scanners is not recommended.

Mobile assessment of visual function helps to prevent Re-Injury in elderly patients with recent hip fractures.

INTRODUCTION: Patients undergoing surgery due to hip fracture face an elevated risk of a subsequent fall during rehabilitation. An important contributing factor to this risk is deteriorated visual function, often responsive to intervention. This study aims to explore differences in visual acuity (VA) and stereovision (SV) between individuals with a history of fall-related hip injuries (study group) and age-matched controls, utilizing a mobile application (EuvisionTab, ET) to distinguish age-related visual decline from pathological vision. MATERIALS & METHODS: A total of 32 and 71 participants were enrolled in the study and control groups, respectively (mean age: 74.9 years, range: 60-96). Monocular logMAR VA was measured using a tablet by means of an adaptive threshold-search algorithm. SV was assessed using low-dot density static and dynamic random dot stereograms. An age-dependent reference limit for VA was established. For ET stereotests, the number of correctly identified optotypes out of 10 random presentations served as the measure for further comparisons. Visually impaired status in the study group was determined if patients failed either the VA threshold or the SV criteria. RESULTS: In the control group, an apparent but statistically nonsignificant decline in VA was observed, while stereovision remained stable and did not exhibit significant age-related variations based on ET stereotests. Conversely, the study group demonstrated significantly worse results in monocular VA (p = 0.0032) and for both stereotests (p = 0.018 for static, p = 0.036 for dynamic) according to paired samples t-test and chi-square test, respectively. Hip injuries were significantly associated with visual impairment (OR = 4.88, p = 0.0012). DISCUSSION: This study focuses on one possible risk factor of elderly falls, namely, vision impairment. Patients with visual decay present a higher incidence of hip injuries compared to age-matched controls. This data suggest that vision screening and, when feasible, restoration of visual function may contribute to the prevention of secondary falls, refractures, or contralateral fractures. A mobile-based screening protocol, executable as part of a postoperative bedside examination and independent of specialized eye care, can be proposed.

Assessing the severity of carpal tunnel syndrome during physical examination by measuring two-point discrimination: Post-hoc analysis of prospectively collected data.

INTRODUCTION: Carpal tunnel syndrome (CTS) commonly presents after distal radius fractures. Assessing its degree of severity is essential to therapeutic decision-making - i.e. operative vs. conservative treatment. The role of the two-point discrimination (2PD) has not yet been evaluated as a potential indicator of severity during physical examination. Therefore, in our cross-sectional study, we aimed to find a correlation between 2PD values and disease severity, based on the gold-standard electromyography and electroneurography (EMG-ENG) and ultrasonography findings. METHODS: We conducted a post-hoc analysis of prospectively assessed CTS patients for 2PD values. We analyzed the correlation between 2PD and EMG-ENG measurement results, patient characteristics, nerve ultrasonography, and relevant CTS questionnaires. CTS severity was determined by EMG-ENG results. The Pearson correlation was calculated between variables. RESULTS: The study included 81 patients. The three pre-determined EMG-ENG severity categories showed a significant correlation between both 2PD values and 2PD severity categories (r= 0.29 [0.07-0.48] and r= 0.26 [0.03-0.45]). Distal sensory latency and conduction velocity values correlated significantly with 2PD categories. However, the correlation coefficients (r= 0.25 [0.02-0.46] and r=-0.24 [-0.37-0.07]) were low. The 2PD severity categories showed no significant correlation with the severity assessed by nerve ultrasound (r=-0.07 [-0.38-0.25]). The 2PD values showed a significant correlation between the values of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire (r= 0.3 [0.06-0.51]). We concluded that the best cut-off value for differentiating severe from non-severe CTS was at the 9.5 mm 2PD cut-off value (sensitivity = 0.65 [0.45-0.81], specificity = 0.71[0.58-0.82], AUC = 0.71 [0.59-0.83]). CONCLUSION: There is a significant correlation between 2PD values and the severity of carpal tunnel syndrome as determined by EMG-ENG; however, they are not interchangeable. Based on the results of our study, we propose that measuring two-point discrimination may be a quick and easy, reliable and cost-effective screening method to assess the severity of carpal tunnel syndrome following distal radius fractures.

Diagnostic accuracy of ultrasonography in acute lateral ankle ligament injury: A systematic review and meta-analysis.

BACKGROUND: The gold standard diagnostic method for acute lateral ankle ligament sprain is magnetic resonance imaging (MRI). However, it is hardly accessible and is time-consuming. Therefore, additional diagnostic methods are warranted. Point-of-care ultrasound, on the other hand, is inexpensive, widely available, time-efficient testing method. PURPOSE: Therefore, the aim of this meta-analysis is to determine the diagnostic accuracy of ultrasound for acute ankle ligament injuries compared to MRI. METHODS: In our systematic review and meta-analysis, we followed the recommendations of the Cochrane Handbook. We searched the following databases from inception to March 31, 2022: Medline (PubMed), EMBASE, and Cochrane Library. Eligible studies investigated the diagnostic accuracy of US compared to MRI for diagnosing acute lateral ankle ligament injuries. Finally, we calculated pooled sensitivity and specificity with a 95 % confidence interval (CI). RESULTS: Eight studies met our eligibility criteria, involving 434 patients. For anterior tibiofibular ligament (ATFL) injury, the summary sensitivity and specificity were Se = 0.97 (CI: 0.89-0.99) and Sp = 0.93 (CI: 0.84-0.97). For calcaneofibular ligament (CFL) injury, the summary sensitivity and specificity were Se.: Se = 0.81 (CI: 0.58-0.93) and Sp = 0.92 [0,81;0,97]. In addition, subgroup analysis based on US performed by different types of investigators was comparable between each other (radiologist group Se = 0.98, CI: 0.24-1, and Sp = 0.91, CI: 0.74-0.97, and the orthopedic/ emergency department group Se = 0.96, CI: 0-1, and Sp = 0.97, CI: 0-1). CONCLUSION: Ultrasound showed high diagnostic accuracy for acute lateral ankle ligament injury, irrespective of the investigator. Therefore, based on the current available data, it could be used in primary diagnostics of acute lateral ankle ligament injury.

Rates and risk factors for failure of reduction in closed reduction in developmental dysplasia of the hip: a systematic review and meta-analysis.

Objective: In developmental dysplasia of the hip (DDH), concentric reduction of dislocated hips cannot be achieved by closed reduction in many cases, and open reduction is required ('failure of reduction'). The incidence of cases requiring open reduction and the significance of risk factors for unsuccessful reduction remain unclear. We investigated the overall rate and the risk factors for failed closed reduction in DDH. Methods: We followed the Cochrane recommendations in our systematic review and meta-analysis. We performed a systematic search in three medical databases to identify all studies reporting on pediatric patients with hip dislocation in DDH on 2 July 2022. Eligible studies reported on the rate of failure in children younger than 36 months. We calculated odds ratios (ORs) with 95% CIs from two-by-two tables (event rate in risk group, event rate in non-risk group). Results: We identified 13 316 studies and included 62 studies (5281 hips) for failure rate and 34 studies (3810 hips) for risk factor analysis. The overall rate of failure in closed reduction was 20%. The risk of failure of reduction increased with the grade of dislocation and was significantly higher for high dislocations (group 0-24: IHDI 4 vs IHDI 2 OR: 17.45, CI: 9.26-32.92; Tönnis 4 vs Tönnis 2 OR: 14.67, CI: 1.21-177.37; Graf IV vs Graf III OR: 3.4, CI: 2.27-5.09). Male gender was also a significant risk factor (OR: 2.27, CI: 1.13-4.56) in group 0-36. Conclusion: Higher grade dislocations and male gender are significant risk factors for failure of reduction in closed reduction in hip dislocation in DDH.

Chemometric analysis of monoterpenes and sesquiterpenes of conifers.

Volatile organic compounds (VOCs) and essential oils of conifers are widely used in the pharmaceutical industry. This work aimed to analyze the VOCs of 30 conifer species representing the Pinaceae and Cupressaceae families. Samples were collected from arboreta in Hungary, and their chemical composition was determined by gas chromatography (SPME-GC/MS); then, chemometric analyses were performed using multivariate methods to identify characteristic VOCs of conifers. Here, we present results for monoterpene and sesquiterpene profiles of the examined conifer samples. The most abundant compounds detected were α-pinene, bornyl acetate, limonene, ß-pinene, ß-caryophyllene, ß-myrcene, δ-3-carene, and ß-phellandrene. The results showed that the following volatiles were characteristic of the conifer groups: sabinene (RRT=6.0) for the cupressoid group (which includes the Cupressaceae species), longifolene (RRT=15.0) and ß-pinene (RRT=6.1) were characteristic of the pinoid group (including Picea, Pinus, and Pseudotsuga species), and camphene (RRT=5.5) and bornyl acetate (RRT=12.6) were characteristic of the abietoid group (including Abies, Cedrus, and Tsuga species). Our results on VOCs in the Pinaceae and Cupressaceae families contribute to the elucidation of biodiversity patterns of conifer species and, in addition, may support the industrial application of terpenes.

Weekend endoscopic retrograde cholangiopancreatography has similar outcomes as weekday procedures-a propensity score match analysis of the Hungarian ERCP Registry.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is essential for the minimally invasive management of biliary and pancreatic disorders. Under certain indications, performing ERCP without delay during the weekend can be important for improving outcomes. Objectives: To compare the outcomes of ERCP performed on weekends and holidays with those of regular weekday ERCPs. Design: Propensity score match analysis of the data from the Hungarian ERCP Registry. Methods: A total of 116 ERCPs were performed during weekends or holidays, and 3144 during weekday working hours. The analyses were performed on 1:2 propensity-matched groups (116 weekend and 232 weekday cases). Results: Weekend ERCPs were mostly performed for acute cholangitis and acute biliary pancreatitis (70% of cases), whereas in the weekday group, only 32% of cases were performed for these indications. No significant difference was found between weekday and weekend ERCPs in terms of the rates of successful (91.38% vs 93.1%, p = 0.565) and difficult (33.62% vs 36.64%, p = 0.511) biliary cannulations. We found no significant differences in the number of adverse events (bleeding, post-ERCP pancreatitis, and 30-day mortality) in ERCPs performed during weekends or weekdays. Moreover, no significant differences in the aforementioned outcomes were detected between the propensity-matched groups. Conclusion: In this propensity-matched study, no significant differences were found in the outcomes of weekend and weekday ERCPs.

Accuracy of conventional versus additive cast-fabrication in implant prosthodontics: A systematic review and meta-analysis of in vitro studies.

PURPOSE: Additive cast-fabrication has yet to be used as commonly in implant prosthodontics as conventional methods. This review aimed to investigate the accuracy of additive cast-fabrication in implant prosthodontics. STUDY SELECTION: The study protocol was registered in the PROSPERO database (CRD42022374972). Reporting was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, following the Cochrane Handbook. Two-arm interventional studies that matched the PICO were included (Population: dental typodonts with implants, Intervention: additive cast-fabrication, Comparator: conventional cast-fabrication, Outcome: positional deviations). A systematic search was conducted in three databases: PubMed (MEDLINE), EMBASE, and the Cochrane Library (CENTRAL). RESULTS: Seven papers were included in the analysis of horizontal, vertical, and root mean square (RMS) deviations. No significant differences were observed between groups. The overall vertical mean deviation of the intervention group was -4.15 µm [-24.88; 16.57], and the pooled mean absolute deviation was 22.43 µm [8.33; 36.54]. In the control group, these values were 19.67 µm [-32.71; 72.04] and 24.62 µm [0.00; 59.42], respectively. The overall horizontal mean deviation in the intervention group was 21.29 µm [-77.10; 119.68], and the pooled mean absolute deviation was 26.96 µm [0.00; 70.81]. In the control group, the overall mean was 1.45 µm [-32.26; 35.15] and the pooled mean absolute deviation was 25.05 µm [9.08; 41.01]. The mean RMS was only slightly larger in the intervention group, with the value of 14.74 µm [-107.26; 136.74]. CONCLUSIONS: Additive cast-fabrication is as accurate as the conventional method for the position of implant analogs.

End-to-end anastomosis provides similar quality-of-life, compared with other reconstructive techniques six months following total mesorectal excision: Systematic review and meta-analysis.

Colorectal malignancy ranked third globally in cancer incidence with 1.9 million cases and nearly 1 million deaths in 2020. Rectal cancer is primarily treated with total mesorectal excision (TME). This study examines surgical, functional, and quality-of-life (QoL) outcomes for different anastomosis types. Pre-registered on PROSPERO (CRD42022368907), the systematic search on November 8, 2022, covered three databases: MEDLINE (via PubMed), Embase, and Cochrane Central. Randomized controlled trials (RCT) assessing adults post-TME, comparing end-to-end anastomosis (EEA) to colonic J-pouch (CJP) and/or side-to-end anastomosis (SEA) were eligible. 29 studies out of 4459 were included. EEA vs. CJP showed no significant differences in anastomotic leakage (AL) (RR: 1.03; CI: [0.84-1.26]) or mortality (RR: 0.77; CI: [0.30-1.98]). At 12 months, the mean bowel movement difference was 1.59/day (CI: [(-)0.66-3.84]). QoL at six and 12 months was similar (SMD: -0.22; CI: [(-)0.82-0.37]). Compared with SEA, EEA had similar AL ratios (RR: 1.59; CI: [0.54-4.72]) and QoL at six months (SMD: -0.04; CI: [(-)0.66-0.58]). EEA demonstrates surgical efficacy comparable to other techniques. Six months postoperatively, EEA's impact on QoL appears similar to CJP or SEA, irrespective of daily stool frequency.

Doxycycline prophylaxis for the prevention of sexually transmitted infections: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To investigate the effects of doxycycline pre- and post-exposure prophylaxis (doxy-PrEP/PEP) on bacterial sexually transmitted infections (STIs) by conducting a systematic review and meta-analysis. METHODS: PubMed, Embase, and CENTRAL were searched for randomized controlled trials (RCTs), including ongoing studies published until November 7, 2023. Our primary endpoint was the incidence of bacterial STIs measured as the number of visits with an STI per total number of visits. Random-effects model was used to estimate pooled effect sizes. The study was registered with PROSPERO, CRD42023478486. RESULTS: We identified six eligible studies containing data from seven articles and four conference abstracts, enrolling men who have sex with men (MSM), transgender women (TGW), and cisgender women (CGW). The pooled analysis of 1,766 participants with 602 newly diagnosed STIs showed a 56% decrease in the overall STI incidence using doxy-PrEP/PEP (RR = 0.44; 95% CI: 0.30-0.65; I2 = 73%). For doxy-PEP, including MSM and TGW only, the RR observed for overall STI incidence was 0.40 (95% CI: 0.28-0.57; I² = 37%), 0.19 (95% CI: 0.08-0.44; I² = 39%) for chlamydia, 0.23 (0.14-0.36; I² = 0%) for syphilis and 0.55 (95% CI: 0.34-0.87; I² = 41%) for gonorrhea. No serious adverse events were reported in the studies. The certainty of evidence regarding the efficacy of doxy-PEP among MSM and TGW was graded as high. CONCLUSION: Doxy-PEP significantly reduces the number of new cases of chlamydia and syphilis and is potentially effective against gonorrhea, influenced by local resistance patterns. Thus, it is a promising tool in the prevention of bacterial STIs among MSM and TGW.

Intraoperative pyloric drainage is unnecessary during esophagectomies: a meta-analysis and systematic review of randomized controlled trials.

Objective: The topic of this meta-analysis is the comparison of gastric conduit esophageal reconstructions with or without pyloroplasty. Background: Surgical procedures, especially minimal invasive esophagectomy (MIE) can be a curative treatment in the early stages of esophageal cancer. Previously, intraoperative pyloroplasty was routinely performed, but nowadays it became debated again in the light of minimally invasive esophagectomy. Methods: A comprehensive search was performed in multiple databases to identify randomized controlled trials investigating the topic. Two independent authors performed the selection based on predefined criteria. Statistical analysis was performed to assess any significant difference, then the bias and quality of the data were estimated. Results: Nine relevant RCTs consisting of 529 patients with esophageal cancer were identified. No significance was found in mortality [odds ratio (OR): 0.85; p = 0.642], anastomosis leakage (OR: 0.57; p = 0.254), respiratory morbidity (OR: 0.51; p = 0.214) and vomiting (OR: 0.74; p = 0.520), however the results about gastric emptying time (GET) were controversial (weighted mean difference (WMD): -67.71; p = 0.009, OR: 2.75; p = 0.072). Significant heterogeneity was not detected except for GET. Trial sequential analyses (TSA) show that a certain conclusion would require more data except in the binary variables of GET. Conclusion: We conclude that the pyloric drainage procedure is not routinely necessary, but further well-designed studies would be needed, especially in Europe.
