Introduction The Mycobacterium abscessus complex is a nontuberculous mycobacteria species that is pervasive in soil and water. Various medical equipment malfunctions, infected surfaces, and patient transmission are potential causes of Mycobacterium abscessus infection in the hospital environment. These cases have an annual prevalence that ranges from 1.4 to 6.6 per 100,000 infections, mainly increasing. Case presentation We present the case of a 23-year-old American female patient who presented to the emergency room with significant abdominal pain between low pelvic sutures and the umbilicus. She reported abdominal pain, pruritus, and boils on her back preventing her from standing upright. The symptoms occurred in the liposuction area after cosmetic surgery in the Dominican Republic. The clinical, radiological, and cultural findings helped diagnose Mycobacterium abscessus infection. We conducted a mini literature review on the published reports of Mycobacterium abscessus . Conclusion Mycobacterium abscessus infection may occur due to surgical procedures abroad. Measures are required to combat Mycobacterium abscessus and reduce its prevalence in hospital settings.

Background Genitourinary syndrome of menopause (GSM) is a common and disturbing issue in the postmenopausal period. Unlike vasomotor symptoms, it has a progressive trend. Our study aims to evaluate the efficacy and safety of oxytocin gel versus placebo gel in postmenopausal women with GSM. Methods A systematic review and meta-analysis synthesizing randomized controlled trials (RCTs) from Web of Science, SCOPUS, PubMed, and Cochrane Central Register of Controlled Trials databases on January 18, 2023. Keywords such as “oxytocin,“ “intravaginal,“ “vaginal,“ “atrophic,“ and “atrophy” were used. We used Review Manager (RevMan) version 5.4 in our analysis. We used the risk ratio (RR) for dichotomous outcomes and the mean difference (MD) for continuous outcomes; both were presented with the corresponding 95% confidence interval (CI) and were calculated with the Mantel-Haenszel or inverse variance statistical method. Cochrane’s Q test and the I 2 statistic were used as measures of statistical inconsistency and heterogeneity. The Cochrane Risk of Bias Tool for RCTs was used for the quality assessment of the included studies. Results Seven studies with 631 patients were included. Regarding the maturation index, there was a statistically insignificant increase in the oxytocin arm (MD = 12.34, 95% CI (-12.52-37.19), P  = 0.33). Clinically assessed vaginal atrophy showed a statistically significant reduction in the oxytocin group (RR = 0.32, 95% CI (0.23 − 0.10), P  < 0.00001). For dyspareunia, vaginal pH, and histological evaluation of vaginal atrophy, there was a statistically insignificant difference between the two groups (RR = 1.02, 95% CI (0.82–1.27), P  = 0.84), (MD = -0.74, 95% CI (-1.58-0.10), P  = 0.08), and (MD = -0.38, 95% CI (-0.82-0.06), P  = 0.09), respectively. There was no significant difference in the safety profile between the two groups as measured by endometrial thickness (MD = 0.00, 95% CI (-0.23-0.23), P  = 0.99). Conclusions Although oxytocin has been proposed as a viable alternative to estrogen in the treatment of GSM, our findings show the opposite. Larger, high-quality RCTs are needed to confirm or refute our results. Trial registration PROSPERO registration number CRD42022334357.

Background and Aim Some studies reported a positive link between familial Mediterranean fever (FMF) and epicardial adipose tissue. Our meta‐analysis aimed to evaluate whether there is a significant association between FMF and increased epicardial adipose tissue thickness. Methods We searched the following databases: PUBMED, WOS, OVID, SCOPUS, and EMBASE. Inclusion criteria were any original articles that reported epicardial adipose tissue in FMF patients with no age restriction, excluding reviews, case reports, editorials, animal studies, and non‐English studies. Thirty eligible studies were screened full text but only five studies were suitable. We used RevMan software (5.4) for the meta‐analysis. Results The total number of patients included in the meta‐analysis in the FMF patients group is 256 (mean age = 24.3), and the total number in the control group is 188 (mean age = 24.98). The pooled analysis between FMF patients and controls was [mean difference = 0.82 (95% CI = 0.25–1.39), p‐value = 0.005]. We observed heterogeneity that was not solved by random effects (p > 0.00001). We performed leave one out test by removing the Kozan et al. study, and the heterogeneity was solved (p = 0.07), and the results were (MD = 0.98, 95% CI = 0.52–1.43, p‐value < 0.0001). Conclusion FMF patients are at increased risk of developing epicardial adipose tissue compared to controls. More multicenter studies with higher sample sizes are needed to support our results.

BackgroundWarfarin's therapeutic effect is affected by many factors, including diet modifications. The impact of Ramadan fasting on warfarin is controversial. The aim of this systematic review and meta-analysis was to investigate the effect of Ramadan fasting on patients taking warfarin.MethodsA literature search was done in PubMed, WOS, Scopus, and Embase from inception to May 24, 2021. All relevant studies measuring the international normalized ratio (INR), time in therapeutic range (TTR), or the number of patients within therapeutic range before, during, and after Ramadan were assessed by full-text screening for achieving all of the inclusion criteria. We used the Newcastle–Ottawa Scale for quality assessment and RevMan 5.4 software for meta-analysis.ResultsA total of five studies with 446 patients were included in the meta-analysis. The patients served as their own control. Our pooled analyses showed no significant difference during Ramadan compared to pre-Ramadan (MD: 0.08; 95% CI: − 0.00, 0.15; P = 0.06) and post-Ramadan (MD: − 0.00; 95% CI: − 0.14, 0.14; P = 1.00, respectively). There was only a significant increase in the risk ratio of supratherapeutic INR when comparing post-Ramadan vs. pre-Ramadan (RR: 1.69; 95% CI: 1.22, 2.33; P = 0.001). However, there was no significant risk for supratherapeutic INR during Ramadan compared to pre-Ramadan or post-Ramadan; the number of patients within the therapeutic range of INR during Ramadan compared to pre-Ramadan; and TTR during Ramadan, pre-Ramadan, and post-Ramadan.ConclusionRamadan fasting did not affect INR level, TTR, or the number of patients within the therapeutic range before, during, and after Ramadan. However, there was a possibility of achieving a supratherapeutic INR post-Ramadan compared to pre-Ramadan. Therefore, INR monitoring and warfarin dose adjustments accordingly are recommended after Ramadan.

Some clinical trials reported conflicting results about the efficacy of anterior lateral electrode compared with anterior posterior electrode in electrical cardioversion of atrial fibrillation, and some studies reported no difference in the efficacy between the two procedures. Our aim is to perform a meta-analysis to compare the efficacy of anterior lateral electrode versus anterior posterior electrode in external cardioversion of atrial fibrillation. We searched the following databases: PUBMED, WOS, OVID and SCOPUS. Inclusion criteria were clinical trials that compared anterior lateral electrode with anterior posterior electrode in external cardioversion of atrial fibrillation. We excluded cohort studies, case reports, editorials and animal studies. RevMan software (5.4) was used to perform the meta-analysis. Cardioversion rate outcome was presented as Odds ratios (OR) with 95% confidence interval (CI). After full text screening, 11 trials were included in the analysis. The total number of patients included in the study is 1845. The pooled analysis showed a statistically significant association between anterior lateral electrode and increased cardioversion rate of atrial fibrillation compared with anterior posterior electrode (OR = 1.40, 95% CI = 1.02 to 1.92, p-value = 0.04). We observed no heterogeneity among studies (P= 0.14, I² = 32%). No publication bias was observed. Subgroup analysis revealed a statistically significant association between anterior lateral electrode and increased cardioversion rate of atrial fibrillation compared with anterior posterior electrode in subgroups of less than 5 shocks, patients with 60years-old or more and patients with left atrial diameter > 45 mm (OR= 1.72, 95% CI = 1.17 to 2.54, p value = 0.006), (OR= 1.73, 95% CI = 1.18 to 2.54, p value= 0.005), and (OR= 1.86, 95% CI = 1.04 to 3.34, p value = 0.04), respectively. Our meta-analysis revealed that anterior lateral electrode is more effective than anterior posterior electrode in external cardioversion of atrial fibrillation. Subgroup analysis showed that patients who received less than 5 shocks, patients with 60 years-old or more and patients with left atrial diameter > 45 mm benefit from anterior lateral electrode more than anterior posterior electrode in external cardioversion of atrial fibrillation.

The efficacy of anteriolateral versus anterior–posterior electrode positions in the success of atrial fibrillation's (AF) electrical cardioversion is unclear. Our aim is to perform a meta‐analysis to compare the success rate of both electrode positions. PUBMED, WOS, OVID, and SCOPUS were searched. Inclusion criteria were clinical trials that compared anterior–lateral with anterior–posterior electrodes in external cardioversion of AF. After the full‐text screening, 11 trials were included in the analysis. The total number of patients included in the study is 1845. The pooled analysis showed a statistically significant association between anterior–lateral electrode and increased cardioversion rate of AF (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.02–1.92, p = .04). Subgroup analysis revealed a statistically significant association between the anterior–lateral electrode and increased cardioversion rate of AF in subgroups of less than five shocks, patients with 60 years old or more and patients with left atrial (LA) diameter >45 mm (OR = 1.72, 95% CI = 1.17–2.54, p = .006), (OR = 1.73, 95% CI = 1.18–2.54, p = .005), and (OR = 1.86, 95% CI = 1.04–3.34, p = .04), respectively. Anteriolateral electrode is more effective than anterior–posterior electrode in external cardioversion of AF, particularly in patients who have received less than 5 shocks, are 60 years old or older and have a LA diameter greater than 45 mm. Anterior–lateral versus anterior–posterior electrodes in external cardioversion of atrial fibrillation. A meta‐analysis

Background and Aims Some studies have suggested that earlier initiation of antibiotics has shown positive outcomes in sepsis patients. We aimed to do a systematic review and meta‐analysis to evaluate the effect of prehospital administration of antibiotics on 28 days mortality and length of stay in hospital and intensive care unit for sepsis patients. Methods We formulated a search strategy and used it on search databases PubMed, Scopus, Web of Science, and Embase. We then screened the records for eligibility and included controlled studies, either clinical trials or cohort studies reporting prehospital antibiotic administration for sepsis patients. We excluded duplicates, books, conferences' s, case reports, editorials, letters, author responses, not English studies, and studies with nonavailable full text. Animal and lab studies were also excluded. Results The total number of studies identified is 1811, 19 were eligible for systematic review and 4 for meta‐analysis (three cohort and one clinical trial). The total number of sepsis patients in the four included studies in the 28 days mortality outcome was 3523 (1779 took prehospital antibiotics and 1744 did not take prehospital antibiotics). Of 1779 who took the antibiotics, 190 died, and of 1744 who did not take antibiotics, 292 died (95% confidence interval 0.68–0.97, p = 0.02). Conclusion This meta‐analysis reveals that receiving prehospital antibiotics can significantly lower mortality in sepsis patients compared to patients who do not receive prehospital antibiotics. However, more clinical trials and multicenter prospective studies with high sample sizes are needed to get strong evidence supporting our findings.

Background and Aim Cardiopulmonary resuscitation (CPR) in full‐coded patients requires effective chest compressions with minimal interruptions to maintain adequate perfusion to the brain and other vital organs. Many novel approaches have been proposed to attain better organ perfusion compared to traditional CPR techniques. The purpose of this review is to investigate the safety and efficacy of heads‐up CPR versus supine CPR. Methods We searched PubMed Central, SCOPUS, Web of Science, and Cochrane databases from 1990 to February 2021. After the full‐text screening of 40 eligible studies, only seven studies were eligible for our meta‐analysis. We used the RevMan software (5.4) to perform the meta‐analysis. Results In survival outcome, the pooled analysis between heads‐up and supine CPR was (risk ratio = 0.98, 95% confidence interval [CI] = 0.17–5.68, p = 0.98). The pooled analyses between heads‐up CPR and supine CPR in cerebral flow, cerebral perfusion pressure and coronary perfusion pressure outcomes, were (mean difference [MD] = 0.10, 95% CI = 0.03–0.17, p = 0.003), (MD = 12.28, 95% CI = 5.92–18.64], p = 0.0002), and (MD = 8.43, 95% CI = 2.71–14.14, p = 0.004), respectively. After doing a subgroup analysis, cerebral perfusion was found to increase during heads‐up CPR compared with supine CPR at 6 min CPR duration and 18 to 20 min CPR duration as well. Conclusion Our study suggests that heads‐up CPR is associated with better cerebral and coronary perfusion compared to the conventional supine technique in pigs' models. However, more research is warranted to investigate the safety and efficacy of the heads‐up technique on human beings and to determine the best angle for optimization of the technique results.

Muscle-invasive bladder cancers (MIBCs) is a group of molecularly heterogonous diseases that could be stratified into subtypes with distinct clinical courses and sensitivities to chemotherapy. Clinical application of molecular subtypes could help in prediction of neoadjuvant chemotherapy (NAC) responders. Immunohistochemical (IHC) markers such as GATA3, cytokeratin (CK) 5/6, and p53 are associated with these subtypes and are widely available. Human epidermal growth factor receptor 2 (HER2) and epidermal growth factor receptor (EGFR) are mutated in multiple cancers including MIBC and are potential therapeutic targets. HER2/EGFR status of MIBC subtypes has not been investigated. Tissue microarrays (TMAs) were constructed from transurethral resection of the bladder tumor (TURB) specimens and stained with GATA3,CK5/6,p53 and HER2 in addition to Quantitative Reverse Transcription PCR for detection of EGFR gene. Of the total cases, 45% were luminal, 36.7% basal and 18.3% p53 wild subtype (p53-WT). Univariate analysis showed that overall survival (OS) and disease-free progression survival (DFS) were significantly longer for luminal subtype. In multivariate analysis, molecular subtype, HER2 status and LV invasion were independent prognostic factors for DFS and OS. Basal subtype showed a significantly better response to NAC. HER2 expression was significantly higher in luminal while EGFR expression was significantly higher in basal subtype. Kaplan-Meier survival curves revealed a significant longer OS and DFS for HER2 negative than positive cases. MIBC can be stratified using a simple IHC panel [GATA3,CK5/6,P53] into clinically relevant prognostic molecular subtypes. Basal tumors are aggressive and respond well to NAC while luminal have better OS. P53-WT tumors are chemoresistant and require further treatments. HER2 and EGFR are potential therapeutic targets for molecular subtypes of MIBC where luminal tumors are more likely to benefit from HER2 and basal from EGFR directed therapies.

Pseudomonas spp are considered a common milk-associated psychotropic bacteria, leading to milk deterioration during storage; therefore, our study aimed to study the distribution of Pseudomonas aeruginosa in raw milk and its associated products then studying the growth behavior of P. aeruginosa in milk after employing chitosan nanoparticles (CsNPs 50, 25, and 15 mg/100ml) and selenium nanoparticles (SeNPs 0.5, 0.3 and 0.1 mg/100ml) as a trial to control the bacterial growth in milk during five days of cooling storage. Our study relies on the ion gelation method and green synthesis for the conversion of chitosan and selenium to nanosized particles respectively, we subsequently confirmed their shape using SEM and TEM. We employing Pseudomonas selective agar medium for monitoring the bacterial growth along the cooling storage. Our findings reported that high prevalence of Pseudomonas spp count in raw milk and kareish cheese and high incidence percent of P. aeruginosa in ice cream and yogurt respectively. Both synthesized nanoparticles exhibited antibacterial activity in a dose-dependent manner. Moreover, CsNPs50 could inhibit the P. aeruginosa survival growth to a mean average of 2.62 ± 1.18 log10cfu/ml in the fifth day of milk cooling storage; also, it was noted that the hexagonal particles SeNPs0.5 could inhibit 2.49 ± 11 log10cfu/ml in comparison to the control P. aeruginosa milk group exhibited growth survival rate 7.24 ± 2.57 log10cfu/ml under the same conditions. In conclusion, we suggest employing chitosan and selenium nanoparticles to improve milk safety and recommend future studies for the fate of nanoparticles in milk.
