Meta-Analysis
There have been increased reports of orthostatic intolerance post-bariatric surgery. However, the prevalence, pathophysiology and long-term outcomes have not been well described. Therefore, we sought to summarize evidence of orthostatic intolerance after bariatric surgery. We conducted a systematic review using PubMed, Scopus, CINAHL, Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (CENTRAL) to identify relevant articles from the date of inception until 1st April 2020. Study selection, data extraction and quality assessment of the included studies were performed independently by two reviewers. The findings of the included studies were narratively reported. When feasible, a meta-analysis was done to summarize the relevant results. We included 20 studies (n = 19 843 participants) reporting findings of 12 prospective cohort studies, 5 retrospective cohort studies, 2 cross-sectional studies and one randomized controlled trial. The 5-year cumulative incidence of orthostatic intolerance was 4.2% (one study). Common clinical presentations of orthostatic intolerance were lightheadedness, dizziness, syncope and palpitation. The pooled data suggested improvement in overall cardiac autonomic function (sympathetic and parasympathetic) post-bariatric surgery. In addition, a significant systolic blood pressure drop may reflect a reset of the balance between the sympathetic and parasympathetic nervous systems after weight loss in the pooled analysis. Existing literature on orthostatic intolerance post-bariatric surgeries was limited or of low quality, and larger studies are needed to know the true incidence of orthostatic intolerance post-bariatric surgeries and the pathophysiology. We found one study reporting the 5-years cumulative incidence of orthostatic intolerance post-bariatric surgeries as only 4.2%. This could challenge the idea of increased orthostatic intolerance prevalence post-bariatric surgeries. Registration The review protocol was registered at the International Prospective Register of Systemic Reviews PROSPERO (CRD42020170877).

Review
Tongxinluo capsule (TXLC) is a commonly used Chinese medicine for unstable angina pectoris (UA). This article aimed to clarify the safety and efficacy of TXLC as an adjunctive treatment for UA. Two reviewers searched 7 databases from inception to August 2021, and performed literature screening and information extraction independently. The meta-analysis was implemented after evaluating the methodological quality of each randomized controlled trial (RCT) by the Cochrane Risk of Bias tool. Sensitivity analyses were conducted for testing the stability of the results, and the Begg and Egger tests were performed for any potential publication bias. After eligibility assessment, 42 RCTs with a total of 5,421 participants were included. Evidence showed that TXLC reduced the rate of cardiovascular events [RR = 0.29, 95% CI (0.19, 0.45), < 0.00001, = 0%] {including cardiovascular mortality [RR = 0.16, 95% CI (0.03, 0.88), = 0.03, = 20%], the incidence of acute myocardial infarction [RR = 0.27, 95% CI (0.13, 0.57), = 0.0006, = 0%] and the occurrence of revascularization [RR = 0.28, 95% CI (0.15,0.54), = 0.0001, = 0%]}, all-cause mortality [RR = 0.25, 95% CI (0.06, 0.99), 0.05, = 19%], recurrence of angina [RR = 0.25, 95% CI (0.11, 0.61), 0.002, = 0%], the number of ST-segment depression [MD = -0.45, 95% CI (-0.69, -0.20), 0.0005, = 0%], the summation of ST-segment depression [MD = -0.70, 95% CI (-1.08, -0.32), 0.0003, = 70%] and the hypersensitive C-reactive protein level [MD = -2.86, 95% CI (-3.73, -1.99), < 0.00001, = 86%], increased the nitric oxide level [MD = 11.67, 95% CI (8.33, 15.02), < 0.00001, = 33%], improved the electrocardiogram change [RR = 1.23, 95% CI (1.16, 1.30), < 0.00001, = 0%] and the clinical efficacy in UA [RR = 1.26, 95% CI (1.21, 1.32), < 0.00001, = 24%], and relieved the symptoms of angina pectoris {including chest pain or tightness [RR = 1.13, 95% CI (0.97, 1.32), = 0.12, = 30%], palpitations [RR = 1.47, 95% CI (1.18, 1.84), = 0.0007, = 0%], shortness of breath [RR = 1.53, 95% CI (1.24, 1.88), < 0.0001, = 0%], and asthenia [RR = 1.69, 95% CI (0.83, 3.43), = 0.15, = 90%]}. The most common adverse effect was gastrointestinal symptoms which could be relieved and eliminated through dose reduction, medication time adjustment and symptomatic remedy. Collectively, TXLC was effective and considerably safe for UA. However, due to the unavoidable risk of bias, these results must be interpreted with caution and further verified by large-scale and high-quality RCTs. www.crd.york.ac.uk/PROSPERO/, identifier CRD42021232771.

In the last few decades, there has been a rapid development in cancer therapies and improved detection strategies, hence the death rates caused by cancer have decreased. However, it has been reported that cardiovascular disease has become the second leading cause of long-term morbidity and fatality among cancer survivors. Cardiotoxicity from anticancer drugs affects the heart's function and structure and can occur during any stage of the cancer treatments, which leads to the development of cardiovascular disease. To investigate the association between anticancer drugs for non-small cell lung cancer (NSCLC) and cardiotoxicity as to whether: different classes of anticancer drugs demonstrate different cardiotoxicity potentials; different dosages of the same drug in initial treatment affect the degree of cardiotoxicity; and accumulated dosage and/or duration of treatments affect the degree of cardiotoxicity. This systematic review included studies involving patients over 18 years old with NSCLC and excluded studies in which patients' treatments involve radiotherapy only. Electronic databases and registers including Cochrane Library, National Cancer Institute (NCI) Database, PubMed, Scopus, Web of Science, ClinicalTrials.gov and the European Union Clinical Trials Register were systematically searched from the earliest available date up until November 2020. A full version protocol of this systematic review (CRD42020191760) had been published on PROSPERO. A total of 1785 records were identified using specific search terms through the databases and registers; 74 eligible studies were included for data extraction. Based on data extracted from the included studies, anticancer drugs for NSCLC that are associated with cardiovascular events include bevacizumab, carboplatin, cisplatin, crizotinib, docetaxel, erlotinib, gemcitabine and paclitaxel. Hypertension was the most reported cardiotoxicity as 30 studies documented this cardiovascular adverse event. Other reported treatment-related cardiotoxicities include arrhythmias, atrial fibrillation, bradycardia, cardiac arrest, cardiac failure, coronary artery disease, heart failure, ischemia, left ventricular dysfunction, myocardial infarction, palpitations, and tachycardia. The findings of this systematic review have provided a better understanding of the possible association between cardiotoxicities and anticancer drugs for NSCLC. Whilst variation is observed across different drug classes, the lack of information available on cardiac monitoring can result in underestimation of this association. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020191760, identifier PROSPERO CRD42020191760.

: Lactation ketoacidosis is a rare cause of high anion gap metabolic acidosis affecting breastfeeding mothers. We aim to review and analyze all cases of lactation ketoacidosis reported. : A systematic search of PubMed/MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL), identifying relevant case reports published from 1 January 1970 to 31 December 2019. We extracted the following data: the first author, country, year of publication, age of the mother, age of the child, weight/body mass index (BMI) of the mother, precipitating factors, presenting symptoms, biochemical results, treatment, breastfeeding, and time from presentation to the resolution of ketoacidosis. : Sixteen case reports and 1 case series reporting 18 cases of lactation ketoacidosis were found. Presenting symptoms were nausea (72%, 13/18), vomiting (67%, 12/18), malaise (56%, 10/18), abdominal pain (44%, 8/18), dyspnea (33%, 6/18), headache (22%, 4/18), and palpitation (11%, 2/18). Dieting and physical exercise to lose weight were reported in 76% (14/18). The treatments included IV dextrose, sodium bicarbonate, insulin, rehydration, monitoring and replacement of electrolytes, and resumption of a balanced diet. The prognoses were good, with no mortalities. lactation ketoacidosis should be suspected in unwell breastfeeding women with high anion gap metabolic acidosis, after excluding other causes.

OBJECTIVE
School refusers often display somatic symptoms that are temporally related to school attendance. The aim of this systematic review is to summarize characteristics and causes of somatic symptoms and their management in the context of school refusal. Findings of this review may help clinicians in their daily practice.
METHODS
PubMed and PsycINFO databases were systematically searched (according to PRISMA guidelines) for articles mentioning somatic symptoms in school refusal by May 2020. Among 1025 identified studies, 148 were included.
RESULTS
Unspecific somatic symptoms were frequently the first complaints in school refusal. Abdominal pain, headache, nausea, vomiting, muscular or joint ache, diarrhea, dizziness, fatigue, and palpitation were the most commonly encountered symptoms and were usually not accounted for by an identifiable physical disease. Anxiety was the most recurrent etiology found, but physicians' lack of awareness about psychological comorbidities often delayed psychological/psychiatric referral. Successful therapies consisted of dialectical behavior therapy, anxiety management through relaxation/breathing training, and ignoring the somatic symptoms.
CONCLUSIONS
Somatic symptoms in school refusal are frequent but poorly understood. Their management could include interventions targeting anxiety, psychotherapies such as emotional awareness and expression therapy, third-wave behavioral therapies, and psychoeducation. A multidisciplinary approach through strengthened collaboration between school staff, physicians, and psychologists/psychiatrists is needed to improve well-being in children who experience somatic symptoms as related to school avoidance.

BACKGROUND
Depression is recognized as a major public health problem with a substantial impact on individuals and society. Complementary therapies such as acupressure may be considered a safe and cost-effective treatment for people with depression. An increasing body of research has been undertaken to assess the effectiveness of acupressure in various populations with depression, but the evidence thus far is inconclusive.
AIM
To examine the efficacy of acupressure on depression.
METHODS
A systematic literature search was performed on PubMed, PsycINFO, Scopus, Embase, MEDLINE, and China National Knowledge (CNKI). Randomized clinical trials (RCTs) or single-group trials in which acupressure was compared with control methods or baseline in people with depression were included. Data were synthesized using a random-effects or a fixed-effects model to analyze the impacts of acupressure treatment on depression and anxiety in people with depression. The primary outcome measures were set for depression symptoms. Subgroups were created, and meta-regression analyses were performed to explore which factors are relevant to the greater or lesser effects of treating symptoms.
RESULTS
A total of 14 RCTs (1439 participants) were identified. Analysis of the between-group showed that acupressure was effective in reducing depression [Standardized mean differences (SMDs) = -0.58, 95%CI: -0.85 to -0.32, < 0.0001] and anxiety (SMD = -0.67, 95%CI: -0.99 to -0.36, < 0.0001) in participants with mild-to-moderate primary and secondary depression. Subgroup analyses suggested that acupressure significantly reduced depressive symptoms compared with different controlled conditions and in participants with different ages, clinical conditions, and duration of intervention. Adverse events, including hypotension, dizziness, palpitation, and headache, were reported in one study.
CONCLUSION
The evidence of acupressure for mild-to-moderate depressive symptoms was significant. Importantly, the findings should be interpreted with caution due to study limitations. Future research with a well-designed mixed method is required to consolidate the conclusion and provide an in-depth understanding of potential mechanisms underlying the effects.

Meta-Analysis Review
Anxiety and anxiety disorders are associated with adverse cardiovascular outcomes, and reduced quality of life. Despite this, no comprehensive study on the global prevalence of anxiety symptoms and disorders among adult cardiology outpatients exists. This systematic review and meta-analysis aims to provide cardiologists with a precise estimate of the prevalence of anxiety in their outpatient clinics. PubMed, Embase, Cochrane and PsycINFO databases and Google Scholar were searched from database inception to January 23, 2023. Data characteristics were extracted independently by 2 investigators. Ninety-three studies, n = 36,687 participants across 31 countries, were included. Global prevalence of anxiety symptoms/disorders was 28.9% (95%CI 25.7-32.4; 8927/36, 687; I2 = 97.33; n = 93). The highest rates were found in patients presenting with hypertension, 43.6%. Subgroup analyses revealed higher prevalence estimates when using self-report screening compared to gold-standard diagnostic interview. When using diagnostic interview, the highest rates were reported in outpatients with undifferentiated chest pain/palpitations, 19·0%. Panic disorder was the most frequent diagnosis 15.3%, and rates were significantly higher in patients with undifferentiated chest pain/palpitations compared to ischemic heart disease. Higher rates of anxiety were found in studies of outpatients from developing countries, and female outpatients tended to have higher rates compared to males. Anxiety occurred frequently among cardiology outpatients and at a higher rate than estimated in the general population. Given the impact anxiety has on patient outcomes, it is important that effective identification and management strategies be developed to support cardiologists in identifying and treating these conditions in their clinics.

Review
People living with cardiac sarcoidosis (CS) are likely to have worse clinical outcomes and greater impairment on health-related quality of life (HRQoL) than other sarcoidosis manifestations. CS can result in a constellation of intrusive symptoms (such as palpitations, dizziness, syncope/pre-syncope, chest pain, dyspnoea, orthopnoea, or peripheral oedema) and/or life-threatening episodes, requiring consideration of invasive cardiac procedures for diagnosis and for the management of acute events. Additionally, the presence of multisystemic involvement and persistent non-specific sarcoidosis symptoms negatively affect HRQoL. A systematic review was undertaken to explore the impact of CS on HRQoL in adults with CS. Multiple bibliographic databases were searched for studies with HRQoL as primary or secondary outcomes in CS (PROSPERO registration: CRD42019119752). Data extraction and quality assessments were undertaken independently by two authors. From the initial 1609 identified records, only 11 studies included CS patients but none specifically reported HRQoL scores for CS patients. The average representation of CS patients was 14.5% within these cohorts (range 2-22%). The majority (73%) was conducted in single-centre tertiary care settings, and only one study (9%) included longitudinal HRQoL data. CS patients were among those sarcoidosis patients with impaired HRQoL and worse outcomes, requiring higher doses of sarcoidosis-specific therapy which contribute to further deterioration of HRQoL. Sarcoidosis studies do not incorporate stratified HRQoL scores for CS patients. While there is a need for longitudinal and multicentre studies assessing HRQoL outcomes in CS cohorts, the development of CS-specific tools is also needed.

Review
Caffeinated drinks are the most widely consumed beverages globally and their intake has increased in the elderly. Caffeine exhibits dose-dependent adverse effects. Low to moderate doses cause anxiety, restlessness, irritability, and nausea. High doses of 3-5g can affect different physiological systems and lead to detrimental effects like palpitations, hypertension, agitation, seizures, and coma. Low-dose aspirin is the most used anticoagulant in preventing ischemic vascular events. An increased risk of intracranial hemorrhage is associated with low-dose aspirin with an intensified intracerebral hemorrhage risk. The aim of this research is to explore the association between caffeine and aspirin in causing lethal intracranial hemorrhage in the older population. Because of the devastating nature of intracranial hemorrhages and the inconsistent published data on the risk of intracranial hemorrhage in individuals taking both aspirin and caffeine, we conducted a systematic review considering the elderly population. We conducted the study following the reporting guidelines for systematic review and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. Inclusion and exclusion criteria were determined. Data was collected from PubMed, PubMed Central® (PMC), National Library of Medicine (MEDLINE), Google Scholar, Multidisciplinary Digital Publishing Institute (MDPI), and Web of Science by applying keywords and Medical Subject Headings (MeSH) terms individually. Our initial search yielded 155,270 articles, which were scrutinized, and duplicates were removed for accuracy. Of these, a total of 13 research papers were finally extracted using the PRISMA recommendations and applying other inclusion and exclusion criteria. With the help of our systematic review, we could determine that both aspirin and caffeine portrayed a role in causing intracranial hemorrhage independently, but further studies are recommended to evaluate if both could lead to similar adverse effects when taken collectively.

Review
Pectus excavatum is a congenital chest wall deformity, commonly identified in early childhood, creating a "sunken chest" appearance. Over time, the deformity can worsen, thus impacting cardiopulmonary function and creating significant body image disturbance in patients. The Nuss procedure is a minimally invasive technique in which a curved steel bar is introduced underneath the sternum through small bilateral thoracic incisions to correct the deformity. Most studies regarding the procedure to date focus on outcomes and complications in pediatric patients, however, few studies discuss these results in adult patients. This systematic review aims to analyze common complications and outcomes in patients over the age of 18 who have not undergone any prior intervention for pectus excavatum. The most common complications experienced in adult patients were displacement of the implanted steel bar, infection of the surgical site, pneumothorax, pleural effusion, and chronic postoperative pain. Reoperation was common in patients with a displacement of the bar, chronic pain, and bleeding. Additionally, adult patients routinely required a higher number of steel bars to be placed to correct the deformity. Despite evidence that the rate of complications increases with age, the majority of adult patients in our included studies were satisfied with the outcome of the procedure with indications of improved self-image and reduced preoperative symptoms such as dyspnea on exertion, palpitations, chest pain, and depression.
