BACKGROUND AND AIMS: Positron Emission Tomography (PET)-derived myocardial flow reserve (MFR) has been shown to have a role in the diagnosis and prognosis of patients with coronary artery disease (CAD). We performed a systematic review and meta-analysis to summarize the body of literature and synthesize the evidence on the prognostic role of PET-derived MFR in patients with known or suspected CAD. METHODS: A comprehensive literature search of the Medline database from its inception to August 2023, in humans, in any language, was conducted for clinical studies examining the prognostic value of PET imaging in patients of any age, sex, and CAD status. Systematic screening and data extraction of the identified studies were followed by quantitative meta-analysis of PET-MFR's role in predicting adverse clinical events using random effect model. Studies were appraised using the modified Newcastle-Ottawa tool. RESULTS: A total of 21 studies assessing the prognostic role of PET derived MFR in 46,815 patients with known and/or suspected CAD were included (mean (SD) age 66 (4) years, 48% women). The mean follow-up duration was 36 months (range 10-96). Cardiovascular risk factors were prevalent (73% hypertension, 35% diabetes and 67% dyslipidemia). The definition of the composite outcome varied between studies, with various combinations of mortality, non-fatal myocardial infarction, hospitalization, and coronary revascularization. Pooled impaired MFR was significantly associated with an increased risk of adverse outcomes (RR = 2.94, 95% CI 2.42-3.56, p < 0.001). Results were similar in a subgroup of patients with suspected CAD. CONCLUSIONS: The available body of evidence shows that impaired PET-derived MFR measured using different tracers and PET systems is strongly associated with an increased risk of adverse cardiovascular events. Limitations of this review include observational nature of studies, marked heterogeneity in patient populations, inconsistency in thresholds to define abnormal MFR, and differing components for the composite outcome.

We aim to collect the evidence of efficacy of Gentle Guman Touch (GHT) and Yakson Touch in preterm neonates as pain relief, heart rate, oxygen saturation, and urine cortisol level. We made our search through PubMed, Web of Science, Scopus, and Cochrane by the mid of March 2023. Randomized control trials (RCTs) were included, and the Cochrane risk of bias tool was utilized to assess their quality. Using Review Manager software, a meta-analysis was conducted. We computed the mean difference (MD) with a 95% confidence interval (CI) for the continuous data. During the examination, the Neonatal Infant Pain Scale (NIPS) was significantly reduced in the touch group compared to the control group (MD = -3.40, 95% CI [-4.15 to -2.64], P-value= 0.00001). After the examination, the NIPS score was also reduced by both Yakson touch and GHT compared to the control (MD = -2.14, 95% CI [-3.42 to -0.85], P-value <0.00001). Yakson touch and GHT are non-pharmacological, easy, and safe methods that can be used for painful interventions to reduce the pain experience of preterm infants from variable interventions. Both methods improved infant sleep and behavior. Preterm infants' heart rates and oxygen saturation were unaffected by Yakson touch or GHT.

Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure worldwide. Systematic search of Pubmed, Cochrane, and Embase was performed in order to find all the articles reporting 10+ years of LSG results. Eleven studies including 1020 patients met the inclusion criteria. Overall weighted mean %TWL was 24.4% (17-36.9%), and remission rates from TD2M to HTN were 45.6% (0-94.7%) and 41.4% (0-78.4%), respectively. De novo GERD had an overall prevalence of 32.3% (21.4-58.4%), and five cases (0.5%) of Barrett's disease were reported. Revisional surgery was required for 19.2% (1-49.5%) of patients, Roux-en-Y gastric bypass being the most common secondary procedure.

Platynosomum sp. is a parasite that infects the liver and biliary tract of domestic and wild cats, causing platynosomiasis. A systematic review with meta-analysis was performed to determine the global prevalence and distribution of Platynosomum sp. based on epidemiological studies and case reports. A total of 73 articles met the inclusion criteria, including 46 studies of an epidemiological nature and 27 case report articles, comprising 35 affected animals. Meta-analysis of epidemiological studies revealed an overall prevalence of 17.8%, with high heterogeneity. Central America had the highest prevalence at 64.1%, followed by South America at 15.1%. Necropsy was the primary diagnostic method, followed by morphological detection of eggs in faeces at 29.3% and 12.5%, respectively. The analysis of case reports highlighted a greater number in South America and confirmed the presence of the parasite in countries where no epidemiological studies were obtained. The most infected animals were those that met the criteria of being mixed-breed, over 4 years old, and having unrestricted outdoor access, but no gender predilection was observed. General comorbidities were the most observed, followed by icterus. In addition, pathological changes were observed in the necropsied animals of the case reports, and the presence of thickening of the ducts and gallbladder was mainly identified, followed by fibrosis and hyperplasia, linked to the presence of an adult parasite. In conclusion, this systematic review with meta-analysis revealed a significant prevalence of Platynosomum sp. at a global level, mainly in the Americas, and that comprehensive studies are necessary for a more reliable prevalence, considering that this is a parasite of great importance for feline medicine.

PURPOSE: Peroneus tertius (PT) or Fibularis tertius, a muscle of the anterior compartment of the leg is very distinctive to the Homo sapiens. This is because of the evolutionary acquisition of bipedal gait along with the eversion of the foot, which are unique to humans. It is considered as the fifth tendon of the extensor digitorum longus. Variations in the attachments of PT can cause stress fractures like the Jones fracture. PT has been extensively used in tendoplasty, tendon transfer and resection of the foot. The study aims to transpose the knowledge in variations of the morphology of PT from bench to bedside. METHODS: Routine dissection of a 64-year-old male cadaver revealed bilateral variations in the insertion of PT. This was documented photographically. The findings prompted a systematic literature review on the morphological variations of PT. An exhaustive search was undertaken through PubMed and Google Scholar databases to identify the published literature related to variations in the morphology of PT. Related anatomical studies of the variations in peroneus tertius were identified and a review of the literature was performed. RESULTS: Variations in the insertion of PT were observed bilaterally in the cadaver dissected by us. Statistical analysis revealed the absence of PT in 7.03% of lower limbs. 10% of studies showed accessory and duplicated PT each. Out of 20 articles reviewed, 51 lower limbs showed variation in origin, 230 lower limbs showed variations in insertion and 161 lower limbs showed other variations. CONCLUSION: PT muscle flap and tendon grafts are used in correcting the laxity of the ankle joint and foot drop. Absence of PT plays a crucial role in altering the mechanics of stress fractures of the 5th metatarsal. Thus, knowledge of the morphology of PT is crucial for plastic surgeons and orthopedic surgeons.

AIMS: This study aimed to identify and evaluate tools and resources used to support the implementation of workplace healthy food and drink policies, primarily in Australia and New Zealand. METHODS: A scoping grey literature review included searches of government agencies and non-governmental organisations' websites in six English-speaking countries, public health nutrition intervention databases and Google search engine queries. Paper-based and digital tools were included if they were written in English, referred to within a policy or on a policy's website, and primarily targeting supply-side stakeholders. Tools were evaluated on two domains: 'Features' (summarised descriptively) and 'Usability and Quality' (with inter-rater reliability scores calculated using an intraclass correlation coefficient). RESULTS: Twenty paper-based tools were identified relating to Australian (n = 14) and New Zealand (n = 6) policies, and a further six digital tools were identified from Australia (n = 3) and Canada (n = 3). Target audiences included workplace managers, food providers and suppliers. The paper-based tools focused on general implementation guidance. In contrast, digital tools tended to support specific elements of policy implementation. 'Usability and Quality' scores ranged from 2.9 to 4.5 (out of 5.0) for paper-based tools, and 3.9 to 4.2 for digital tools, with a moderate agreement between reviewer scores (intraclass correlation coefficient 0.523, p = 0.010). CONCLUSIONS: A range of tools have been developed to support the implementation of workplace healthy food and drink policies. Understanding the strengths and limitations of current tools will assist in developing improved aids to support policy implementation.

BACKGROUND: Neonates and infants have a higher perioperative risk of cardiac arrest and mortality than adults. The Human Development Index (HDI) ranges from 0 to 1, representing the lowest and highest levels of development, respectively. The relation between anaesthesia safety and country HDI has been described previously. We examined the relationship among the anaesthesia-related cardiac arrest rate (ARCAR), country HDI, and time in a mixed paediatric patient population. METHODS: Electronic databases were searched up to July 2022 for studies reporting 24-h postoperative ARCARs in children. ARCARs (per 10,000 anaesthetic procedures) were analysed in low-HDI (HDI<0.8) vs high-HDI countries (HDI≥0.8) and over time (pre-2001 vs 2001-22). The magnitude of these associations was studied using systematic review methods with meta-regression analysis and meta-analysis. RESULTS: We included 38 studies with 5,493,489 anaesthetic procedures and 1001 anaesthesia-related cardiac arrests. ARCARs were inversely correlated with country HDI (P<0.0001) but were not correlated with time (P=0.82). ARCARs did not change between the periods in either high-HDI or low-HDI countries (P=0.71 and P=0.62, respectively), but were higher in low-HDI countries than in high-HDI countries (9.6 vs 2.0; P<0.0001) in 2001-22. ARCARs were higher in children aged <1 yr than in those ≥1 yr in high-HDI (10.69 vs 1.48; odds ratio [OR] 8.03, 95% confidence interval [CI] 5.96-10.81; P<0.0001) and low-HDI countries (36.02 vs 2.86; OR 7.32, 95% CI 3.48-15.39; P<0.0001) in 2001-22. CONCLUSIONS: The high and alarming ARCARs among children younger than 1 yr of age in high-HDI and low-HDI countries, respectively, reflect an ongoing challenge for anaesthesiologists.

OBJECTIVE: This meta-analysis aimed at estimating the prevalence of postpartum depression (PPD) at different postpartum timepoints in women with antenatal depression (AD) in the three trimesters. We also examined the association between AD and PPD, and estimated the population attributable fraction of PPD to AD. METHODS: This systematic review and meta-analysis identified cohort studies that determined the prevalence of PPD in women who had AD, and those that examined the association between AD and PPD from PubMed, Embase, MEDLINE, CINAHL and PsycINFO. Articles were appraised using the modified Newcastle Ottawa Scale and data were analyzed using Comprehensive Meta-Analysis. RESULTS: Eighty-eight (88) cohort studies with a combined sample size of 1,042,448 perinatal women contributed to the meta-analysis. About 37% pregnant women who had AD, later had PPD. Those with AD had four times higher odds of developing PPD (OR: 4.58; 95% CI = 3.52-5.96). The odds of having PPD were higher when AD was observed in the first or third trimester compared to the second trimester. About 12.8% of PPD cases were attributable to AD. CONCLUSION: The findings should inform future clinical guidelines on the screening, the frequency of screening, and follow-up care in maternal-mental health.

OBJECTIVE: This study aimed to elucidate the diagnostic roles of PAX8 immunohistochemistry in various ovarian tumors. METHODS: We searched through the PubMed database and selected the eligible studies to perform the meta-analysis. The PAX8 immunohistochemical expression rates of various ovarian tumors, including primary and metastatic carcinomas, were analyzed. In addition, the subgroup analysis based on tumor behaviors was performed. RESULTS: The PAX8 expression rates were 0.056 (95% confidence interval [CI] 0.008-0.307), 0.400 (95% CI 0.228-0.600), 0.741 (95% CI 0.578-0.857), and 0.738 (95% CI 0.666-0.799) in normal ovary and benign, borderline, and malignant ovarian tumors, respectively. The PAX8 expression rates of serous and transitional cell carcinomas were 0.937 (95% CI 0.882-0.967) and 0.918 (95% CI 0.841-0.959). In addition, the PAX8 expression rate of mucinous carcinomas was 0.393 (95% CI 0.285-0.512). However, metastatic carcinomas showed a significantly lower PAX8 expression rate than primary ovarian cancers (P < 0.001 in the meta-regression test). In cytologic specimens, PAX8 expression rates of serous and endometrioid carcinomas were 0.905 (95% CI 0.832-0.948) and 0.714 (95% CI 0.327-0.928), respectively. CONCLUSION: PAX8 expression rate was significantly higher in serous ovarian tumors than in mucinous ovarian tumors. In addition, PAX8 expression rates were significantly higher in primary ovarian cancers than in metastatic carcinomas.

OBJECTIVE: Evaluate the efficacy of exercise rehabilitation at improving physical function during active treatment for adults diagnosed with a hematological malignancy. DATA SOURCE: Systematic review with a multilevel meta-analysis of randomized trails was conducted. Four electronic databases, MEDLINE (EBSCOhost), CINAHL, Scopus, and CENTRAL, were searched using key words and medical subject headings. Articles were screened and assessed against the predetermined eligibility criteria. Data extracted were appraised using the Cochrane risk of bias tool for randomized trials and the GRADE guidelines. A meta-analysis examined four key clinical objectives. CONCLUSION: Twelve studies representing a total of 812 participants were included. Analysis of 36 dependent effect sizes from nine studies revealed structured and prescribed exercise interventions improved physical function (SMD = 0.39; 95% CI 0.21-0.57) compared to usual care or an active control. Exercise interventions with a multimodal design consisting of both aerobic and resistance exercise had a statistically significant effect on physical function (P < .001). Exercise intensity also had a statistically significant effect on physical function when prescribed at a moderate (P = .003) and vigorous (P < .001) intensity during active treatment in patients with leukemia or lymphoma. IMPLICATIONS FOR NURSING PRACTICE: This review suggests individuals diagnosed with leukemia or lymphoma can optimize physical function during and immediately post-treatment by attending exercise rehabilitation 3-5 times per weeks performing moderate-vigorous aerobic and resistance exercise. While further research is needed to identify optimal prescription guidelines throughout the treatment continuum, this review underscores the importance for hematology nurses to support patient referrals to exercise oncology professionals to gain positive improvements in physical function.
