RESUMO

Antibiotics are often prescribed in acne treatment; however, Propionibacterium acnes and Staphylococcus epidermidis, the two of the major acne-associated bacteria, developed antibiotic resistance. Essential oils (EOs) present a natural, safe, efficacious and multifunctional alternative treatment. This study aimed to assess the potential anti-acne activity of selected seven EOs commonly used in Mediterranean folk medicine. Antimicrobial activity screening of these oils showed oregano to exhibit the strongest antimicrobial activity with minimum inhibitory concentration (MIC) of 0.34 mg/mL and minimum bactericidal concentration (MBC) of 0.67 mg/mL against P. acnes; and MIC of 0.67 mg/mL and MBC of 1.34 mg/mL against S. epidermidis. The composition of the most effective EOs (oregano and thyme) was determined using gas chromatography-mass spectrometry (GC-MS). Monoterpenoid phenols predominated oregano and thyme EO with thymol percentile 99 and 72, respectively. Thymol showed MIC 0.70 mg/mL against both P. acnes and S. epidermidis whereas MBC was 1.40 and 2.80 mg/mL against P. acnes and S. epidermidis, respectively. Moreover, oregano exhibited the strongest anti-biofilm effect against S. epidermidis with MBIC 1.34 mg/mL and killing dynamic time of 12 and 8 h against P. acnes and S. epidermidis, respectively. Oregano, the most effective EO, was formulated and tested as a nanoemulsion in an acne animal mouse model. The formulation showed superior healing and antimicrobial effects compared to the reference antibiotic. Collectively, our data suggested that oregano oil nanoemulsion is a potential natural and effective alternative for treating acne and overcoming the emerging antibiotic resistance.

RESUMO

BACKGROUND: Children with ADHD were found to have language impairment in many studies. The way they use language in their everyday life may be affected, namely, the pragmatic aspect of language. Measuring the affected parameters in all aspects of language will help to reach better rehabilitation. Thus, this study set out to observe relationships between hyperactivity/impulsivity and inattention with all language domains in 30 Egyptian Arabic-speaking children with ADHD between 4 and ≤7 years old with the aim of better intervention. Children were evaluated to establish the diagnosis of ADHD and its type following the diagnostic criteria of the DSM-V criteria and the Conners' Parent Rating Scale-Revised. Language abilities were assessed by the Pre-school Language Scale 4th edition (Arabic version), the Arabic articulation test, and the Egyptian Arabic Pragmatic Language Test. This assessment covered receptive and expressive language abilities and phonological and pragmatic skills. RESULTS: Compared to norms, it was found that the ADHD children who participated in this study had non-significant language delays in the parameters of the modified PLS-4 test. 70 % of the ADHD children had total pragmatic test scores below their 5th percentile, while 30 % of the children had total pragmatic test scores above their 5th percentile. 50 % of ADHD children failed to master certain sounds corresponding to their phonological age. A statistically significant negative correlation was observed between each of the inattention and hyperactivity/impulsivity scores and the receptive, expressive, total language ages, and pragmatic language scores. CONCLUSION: Children with ADHD in this study did not show major difficulties in areas beyond what would be expected in normally developing children. Most children with ADHD in the present study had problems with pragmatic language aspects that are correlated positively to ADHD symptoms. 50 % of ADHD children failed to master certain sounds corresponding to their chronological age.

RESUMO

Iron deficiency anemia (IDA), which causes greater morbidity and mortality in children, has multifactorial causes, including many helminthic and protozoal infections. Herein, the study aimed to find out the frequency and associated risk of Blastocystis sp. infection among children with IDA, together with the estimation of the serum levels of iron, zinc, copper, and vitamin A. Both stool and blood samples were obtained from 90 children with a confirmed diagnosis of IDA and 90 non-anemic children. Blastocystis sp. was diagnosed by direct stool examination and Invitro cultivation methods. Different hematological parameters were recorded, and the serum level of iron, zinc, copper, and vitamin A was measured in serum samples. The overall predominance of Blastocystis in children was 36.7%, significantly higher (P < 0.001) in children with IDA (55.6%) compared to non-anemic controls (17.8%). Furthermore, Blastocystis infected children were 5.781 times more prone to be anemic (OR = 5.781). All IDA cases with positive Blastocystis infection had a mean hemoglobin level of 9.55 g/dl (moderate anemia). While in other non-infected IDA cases, it was 9.56 g/dl, showing no statistical difference (P = 0.845). Serum levels of zinc, iron, and vitamin A considerably decreased, whereas serum copper levels significantly increased in IDA children infected with Blastocystis. The current research is the first in Egypt to indicate that Blastocystis infection in children is a high-risk factor for developing IDA. Blastocystis infection significantly alters the metabolic and biochemical processes and interferes with the absorption of micronutrients and vitamin A in IDA children.

RESUMO

INTRODUCTION: Morbidity from an emergency laparotomy (EmLap) is difficult to define and poorly understood. Morbidity is a holistic concept, reliant upon an interplay of bio-psychosocial outcomes that evolve long after discharge. To date, no previous study has explored the psychosocial outcomes following EmLap as a collective, nor their change over time. This study aims to describe the holistic morbidity following EmLap within the first year following surgery. METHODS AND ANALYSIS: This is a multicentre, mixed-methods prospective 12-month cohort study with two participant populations: patient participants and family caregivers (FCGs). A target of 160 adult patients who undergo EmLap and can give informed consent will be included in the patient participant group. Patient participants will be asked to complete three patient surveys, incorporating validated patient-reported outcome measures (PROMs) to assess bio-psychosocial outcomes (EuroQol five-dimension five-level (EQ5D-5L), Gastrointestinal Quality Life Index-36, Patient Health Questionnaire-9, Generalised Anxiety Disorder 7, International Trauma Questionnaire, Caregiver Interaction Scale and Fatigue Severity Scale) in the 12 months following surgery. A subgroup of 15 patient participants will be asked to take part in two semistructured interviews at 6 and 12 months. A target of 15 associated family caregivers will be included in the FCG group. FCGs will be asked to take part in a semi-structured interview at 6 months to assess the EmLap impact on the wider support network. The primary outcome will be a change in quality of life (EQ5D-5L) at 12 months. Secondary outcomes will be changes in bio-psychosocial status at 3 and 12 months. Qualitative analysis will allow contextualisation of PROMS and further explore themes of EmLap morbidity. It is anticipated that the results of this study will help inform and develop standards of aftercare for future EmLap patients. ETHICS AND DISSEMINATION: This study has received ethical approval (Wales REC7;12/WA/0297) and will be undertaken in accordance with the principles of Good Clinical Practice. We intend to disseminate study results in peer-reviewed journals and medical conferences, as well as a lay report to study participants. TRIAL REGISTRATION NUMBER: Clinical Trials.gov NCT05281627.

RESUMO

Silybum marianum, known as milk thistle (MT), is traditionally used to manage liver diseases. This study aimed to investigate the role of MT extract topical application as a potential treatment for imiquimod (IMQ)-induced psoriatic lesions in mice with particular emphasis on phosphoinositol-3 Kinase (PI3K)/ protein kinase B (AKT)/ mammalian target of rapamycin (mTOR) and Kelch-like ECH-associated protein 1 (KEAP1)/ nuclear factor erythroid-2-related factor (NRF2)/ nuclear factor-kappa B (NF-κB) molecular cascades involvement. To address this aim, forty male Swiss albino mice were subdivided into four groups (n = 10 mice/group): control, IMQ model, standard group where mice were treated topically with IMQ, then the anti-psoriatic mometasone cream, and MT extract-treated group where mice were treated topically with IMQ followed by MT extract. In most measured parameters, MT extract, rich in silymarin, exhibited potent anti-psoriatic activity comparable to the standard cortisone treatment. MT extract mitigated dorsal skin erythema, scaling, and epidermal thickening, reflected by lowering the Psoriasis Area Severity Index (PASI) score. Moreover, it alleviated IMQ-induced splenomegaly. Mechanistically, the PI3K/AKT/mTOR pathway was the main functional pathway behind such improvements, where it was significantly inhibited by MT extract application. This led to NRF2 activation via KEAP1 downregulation with subsequent anti-inflammatory effect proven by reducing NF-κB, interleukin (IL)-23, and IL-17A and antioxidant ability proven by boosting the antioxidant glutathione and heme oxygenase-1. Such improvements were confirmed by alleviating the histopathological alteration. Thus, MT extract could be a promising therapeutic agent for psoriasis treatment by inhibiting PI3K/AKT/mTOR cascade, along with NRF2 signaling activation.

RESUMO

Inflammatory bowel disease (IBD) patients frequently suffer from depressive disorders as well. The present study was carried out to explore whether treatment with a standardized rice bran extract (RBE) could affect depression-like behavior in rats with dextran sulfate sodium (DSS)-induced colitis. Male Wistar rats were treated with RBE (100 mg/kg/day; p.o.) for 2 weeks. During the second week, colitis was induced by feeding the rats with 5 % (w/v) DSS in drinking water. RBE protected against DSS-induced body weight loss as well as against the macro- and microscopic inflammatory changes of the colon. Additionally, RBE mitigated DSS-induced dysregulation in blood-brain barrier tight junctional proteins, preserved the hippocampal histopathological architecture and improved the animal behavior in the forced swimming test. This was associated with modulation of hippocampal oxidative stress marker; GSH as well as hippocampal pro-inflammatory mediators; NF-ĸB and IL-1ß. Treatment with RBE also led to a profound increase in the hippocampal levels of Sirt1, PGC-1α, Nrf2, and HO-1, which were drastically dropped by DSS. In conclusion, the study revealed the protective effect of RBE against DSS-induced depressive-like behavior through modulation of different parameters along the gut-brain axis and up-regulated the Sirt1/PGC-1α/Nrf2/HO-1 signaling pathway.

RESUMO

INTRODUCTION AND AIM: The optimal composition and duration of antiplatelet therapy after complex percutaneous coronary intervention (PCI) remains unclear. We conducted a meta-analysis to compare 1-3 months of dual antiplatelet therapy (DAPT) followed by monotherapy vs. 12 months of DAPT. METHOD: MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were queried for studies comparing 1-3 months of DAPT followed by monotherapy vs. 12 months of DAPT in the outcomes of complex PCI from inception through January 2023. Outcomes of interest included major bleeding, all-cause mortality, cardiovascular mortality, myocardial infarction (MI), stent thrombosis, target vessel revascularization, and stroke. RESULTS: Compared to 12 months, 1-3 months of dual antiplatelet therapy had a weak association with less major bleeding (OR 0.67; 95 % CI, 0.44-1.00; p = 0.05; I2 = 28 %). There were no significant differences between the shorter and longer antiplatelet therapy in terms of all-cause mortality (OR 0.83; 95 % CI, 0.59-1.16; p = 0.21; I2 = 17 %), cardiovascular mortality (OR 0.87; 95 % CI, 0.53-0.42; p = 0.50; I2 = 0), MI (OR 0.97; 95 % CI, 0.69-1.35; p = 0.82; I2 = 32 %), stent thrombosis (OR 1.17, 95 % CI, 0.77-1.76; p = 0.38; I2 = 0 %), target vessel revascularization (OR 1.05, 95 % CI, 0.58-1.89; p = 0.82; I2 = 64 %), or stroke (OR 1.10, 95 % CI, 0.55-2.17; p = 0.37; I2 = 7 %);. CONCLUSION: Among patients undergoing complex PCI, DAPT for 1-3 months may be associated with less major bleeding but similar rates of cardiovascular events (death, MI, stroke, stent thrombosis, and revascularization) compared to DAPT for 12 months.

RESUMO

INTRODUCTION: Cangrelor is a potent intravenous non-thienopyridine P2Y12 inhibitor. We conducted a network meta-analysis to study the efficacy and safety of cangrelor as compared with the oral P2Y12 inhibition, clopidogrel, or placebo in acute coronary syndromes. METHODS: This meta-analysis followed the Cochrane collaboration guidelines and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocols. Outcomes of interest included all-cause mortality, myocardial infarction, stent thrombosis, target vessel revascularization, major bleeding, minor bleeding, and the need for blood transfusion. RESULTS: The analysis was comprised of 6 studies including 26,444 patients treated with cangrelor, clopidogrel, or placebo. There were no statistically significant differences in the incidence of all-cause mortality, myocardial infarction, stent thrombosis, target vessel revascularization, or major bleeding. Cangrelor was associated with a higher risk of minor bleeding than clopidogrel or placebo, with no difference in requiring blood transfusion. CONCLUSION: Cangrelor has comparable outcomes to clopidogrel in patients with acute coronary syndromes and can be used as a reliable alternative in this population.

RESUMO

Pneumoperitoneum is defined as the presence of free air in the abdominal cavity. The most common cause of pneumoperitoneum is intestinal perforation, which usually requires surgical intervention. Nonsurgical pneumoperitoneum (NPS) is defined as the presence of free air in the abdominal cavity without visceral perforation by an intrathoracic route, which commonly occurs in patients on mechanical ventilation in intensive care units. NSP, when properly diagnosed, can be successfully treated conservatively without surgery, and intensivists and surgeons should be aware of this entity associated with mechanical ventilation to avoid unnecessary surgical intervention.

RESUMO

Mild gastrointestinal symptoms and mild abdominal pain often occur in association with COVID-19. However, acute abdomen and severe abdominal pain warranting urgent surgical treatment are rare. Here we present the case of a 40-year-old man who presented with the clinical picture of a perforated duodenal ulcer. He was eventually found to have COVID-19 and was treated conservatively. In this report, we discuss his course of treatment and review the relevant literature.

RESUMO

BACKGROUND: Numerous studies have evaluated the beneficial effects of omega-3 fatty acids on inflammatory, autoimmune and renal diseases. However, data about the effects of omega-3 fatty acids on diabetic kidney disease in type 1 diabetes mellitus (T1DM) are lacking. OBJECTIVES: This randomized-controlled trial assessed the effect of oral omega-3 supplementation on glycemic control, lipid profile, albuminuria level, kidney injury molecule-1 (KIM-1) and carotid intima media thickness (CIMT) in pediatric patients with T1DM and diabetic nephropathy. METHODS: Seventy T1DM patients and diabetic nephropathy were enrolled with a mean age 15.2 ± 1.96 years and median disease duration 7 years. Patients were randomly assigned into two groups; intervention group which received oral omega-3 fatty acids capsules (1 g daily). The other group received a matching placebo and served as a control group. Both groups were followed-up for 6 months with assessment of fasting blood glucose (FBG), HbA1c, fasting lipids, urinary albumin creatinine ratio (UACR), KIM-1 and CIMT. RESULTS: After 6 months, omega-3 fatty acids adjuvant therapy for the intervention group resulted in a significant decrease in FBG, HbA1c, triglycerides, total cholesterol, LDL-cholesterol, UACR, KIM-1 and CIMT, whereas, HDL-cholesterol was significantly higher post-therapy compared with baseline levels and compared with the control group (p < 0.05). Baseline KIM-1 levels were positively correlated to HbA1c, UACR and CIMT. Supplementation with omega-3 fatty acids was safe and well-tolerated. CONCLUSIONS: Omega-3 fatty acids as an adjuvant therapy in pediatric T1DM patients with diabetic nephropathy improved glycemic control, dyslipidemia and delayed disease progression and subclinical atherosclerosis among those patients. This trial was registered under ClinicalTrials.gov Identifier no. NCT05980026.

RESUMO

Depression is a serious mood disorder characterized by monoamines deficiency, oxidative stress, neuroinflammation, and cell death. Niacin (vitamin B3 or nicotinic acid, NA), a chief mediator of neuronal development and survival in the central nervous system, exerts neuroprotective effects in several experimental models. AIMS: This study aimed to investigate the effect of NA in lipopolysaccharide (LPS) mouse model of depression exploring its ability to regulate sirtuin1/poly (ADP-ribose) polymerase-1 (PARP-1)/nod-likereceptor protein 3 (NLRP3) signaling. MAIN METHODS: Mice were injected with LPS (500 µg/kg, i.p) every other day alone or concurrently with oral doses of either NA (40 mg/kg/day) or escitalopram (10 mg/kg/day) for 14 days. KEY FINDINGS: Administration of NA resulted in significant attenuation of animals' despair reflected by decreased immobility time in forced swimming test. Moreover, NA induced monoamines upsurge in addition to sirtuin1 activation with subsequent down regulation of PARP-1 in the hippocampus. Further, it diminished nuclear factor-κB (NF-κB) levels and inhibited NLRP3 inflammasome with consequent reduction of caspase-1, interleukin-1ß and tumor necrosis factor-α levels, thus mitigating LPS-induced neuroinflammation. NA also reduced tumor suppressor protein (p53) while elevating brain-derived neurotrophic factor levels. LPS-induced decline in neuronal survival was reversed by NA administration with an obvious increase in the number of intact cells recorded in the histopathological micrographs. SIGNIFICANCE: Accordingly, NA is deemed as a prosperous candidate for depression management via targeting SIRT1/PARP-1 pathway.

RESUMO

AIMS: Depression is one of the common neurological comorbidities in patients with inflammatory bowel disease (IBD). The current study aimed to investigate the potential impact of niacin on colitis-induced depressive-like behavior in rats. MATERIALS AND METHODS: Animals were given 5 % dextran sulfate sodium (DSS) in drinking water for one week to induce colitis. Niacin (80 mg/kg), with or without mepenzolate bromide (GPR109A blocker), was administered once per day throughout the experimental period. Rats were tested for behavioral changes using open field and forced swimming tests. KEY FINDINGS: Niacin significantly ameliorated DSS-induced behavioral deficits and alleviated macroscopic and microscopic colonic inflammatory changes. It also augmented the hippocampal levels of ZO-1, occludin, and claudin-5 proteins, indicating the ability of niacin to restore the blood-brain barrier (BBB) integrity. Moreover, niacin decreased hippocampal IL-1ꞵ and NF-ĸB contents but increased GSH, Sirt-1, Nrf-2, HO-1 concentrations. All these beneficial effects were partially abolished by the co-administration of mepenzolate bromide. SIGNIFICANCE: The neuroprotective effect of niacin against DSS-induced depressive-like behavior was partially mediated through GPR109A-mediated mechanisms. Such mechanisms are also involved in modulating neuronal oxidative stress and inflammation via Sirt-1/Nrf-2/HO-1 signaling pathways.

RESUMO

Organizing pneumonia (OP) is a form of interstitial lung disease that develops in response to acute lung injury. SARS-CoV-2 causes a wide range of lung and extrapulmonary disease, but there are few data suggesting an association between COVID-19 and OP. We describe a patient with COVID-19 pneumonia who developed severe progressive OP with significant morbidity. LEARNING POINTS: COVID-19 pneumonia is one of the secondary causes of organizing pneumonia (OP).Early initiation of steroids in OP is associated with improvement in symptoms and prognosis.A prolonged course of steroids may be needed in COVID-induced OP.

RESUMO

There are limited data on the mortality trends of HCM in the United States. To study the demographics and trends of mortality in patients with HCM, a retrospective cohort analysis was done with mortality data of patients with HCM listed as an underlying cause of death in the US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database (CDC-WONDER) from January 1999 to December 2020. The analysis took place in February 2022. First, we measured HCM-related age-adjusted mortality rate (AAMR) per 100,000 US population stratified by sex, race, ethnicity, and geographic area. We then calculated the Annual Percentage Change (APC) for AAMR for each. A total of 24,655 HCM-related deaths occurred between 1999 and 2020. The AAMR for HCM-related deaths declined from 0.5/100,000 patients in 1999 to 0.2 in 2020. The APC changes are as follows: -6.8 (95% CI: -11.8 to -1.5) from 2002 to 2009, -1.23 (95% CI -13.8 to 13.2) from 2009 to 2014, -6.71 (95% CI -46.2 to 61.7) from 2014 to 2017 and remained at 2.07 (95% CI -26.1 to 41.1) from 2017 to 2020. Men had consistently higher AAMR than women. Overall, AAMR in men was 0.4 (95% CI: 0.4-0.5), and in women was 0.3 (95% CI: 0.3-0.3). A similar trend was noticed in men and women over the years, starting from 1999 (AAMR men: 0.7 and women: 0.4) to 2020 (AAMR men: 0.3 and women: 0.2). AAMRs were highest among black or African American patients 0.6 (95% CI: 0.5-0.6), followed by non-Hispanic and Hispanic white 0.3 (95% CI 0.3-0.3) and Asian or Pacific Islander 0.2 (95% CI 0.2-0.2). There was substantial variation in each region in the US. States such as California, Ohio, Michigan, Oregon, and Wyoming had the highest AAMR. Large metropolitan cities had higher AAMR than non-metropolitan cities. During the study period from 1999 to 2020, HCM-related mortality steadily decreased. The highest AAMR was observed among men, black patients, and residents of metropolitan areas. States such as California, Ohio, Michigan, Oregon, and Wyoming had the highest AAMR.

RESUMO

Nirmatrelvir-ritonavir (Paxlovid) is a brand-new oral antiviral medication for treating mild to severe COVID-19. The Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for ritonavir-nirmatrelvir on December 22, 2021, to treat COVID-19. We describe a case of mild COVID-19 infection who developed severe hyponatremia following the administration of Paxlovid. Clinical and laboratory evaluations suggest SIADH, likely secondary to Paxlovid. The potential side effects of this medication still require further study.

RESUMO

Coronary artery ectasia is associated with an increased risk of acute myocardial infarction. This meta-analysis evaluates outcomes following acute myocardial infarction in patients with pre-existing coronary artery ectasia. A search strategy was designed to utilize PubMed/Medline, EMBASE, and Google scholar for studies including the outcomes of acute myocardial infarction in patients with coronary artery ectasia from inception to February 10, 2022. We reported effect sizes as odds ratio (OR) with a 95% confidence interval (CI). We used I2 statistics to estimate the extent of unexplained statistical heterogeneity. There were 7 studies comprising 13,499 patients in the final analysis. There was no significant difference between patients with coronary ectasia and patients without coronary ectasia in terms of all-cause mortality (OR 0.95; 95% CI 0.58 to 1.56; P = 0.79; I2 = 0%), major adverse cardiovascular events (MACE; OR 4.04; 95% CI 0.34 to 47.57; P = 0.17; I2 = 95%), myocardial re-infarction (OR 2.13; 95% CI 0.83 to 5.47; P = 0.08; I2 = 59%), target vessel revascularization (OR 1.31; 95% CI 0.69 to 2.48; P = 0.21; I2 = 0%), or requiring mechanical supportive devices (OR 1.32; 95% CI 0.22 to 7.83; P = 0.57; I2 = 56%). Acute myocardial infarction in the presence of coronary artery ectasia is not associated with an increased risk of death, MACE, myocardial infarction, or the need for mechanical circulatory support.

RESUMO

INTRODUCTION: The first-generation Watchman 2.5 (W 2.5)TM presented several limitations, such as challenges in implantation within complex left atrial appendage (LAA) anatomies, higher incidence of peri-device leak, device recapture, and device-related thrombus (DRT). The newer generation Watchman FLX (W-FLX)TM was introduced with a modified design aiming to overcome these limitations. The purpose of this meta-analysis is to conduct a comparative assessment of the safety and efficacy of the W-FLX and 2.5 devices in clinical practice. METHOD: The meta-analysis was conducted according to the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). Studies were located through a search strategy utilizing PubMed, Cochrane, Google scholar and MEDLINE from inception to March 2023, with a primary objective to compare the safety and efficacy of the W-FLX and W 2.5 devices. After applying the selection criteria, five studies were included in this analysis. RESULTS: The analysis included five studies comprising 54,727 patients. The W-FLX is associated with an increase in procedural success (OR 7.49 [95% CI 1.98-28.26, P = 0.02; I2 = 0%]), and a significant reduction in mortality (OR 0.52 [95% CI 0.51-0.54, P<0.01; I2 = 0%], major bleeding 0.57 [95% CI 0.51-0.64, P<0.01; I2 = 0%]), device embolism (OR 0.35 [95% CI 0.18-0.70, P = 0.02; I2 = 0%]), and pericardial effusion (OR 0.33 [95% CI 0.26-0.41, P<0.01; I2 = 0%]). The rates of DRT and stroke were similar between the two groups. CONCLUSION: Compared to the W 2.5, the W-FLX was associated with a higher procedural success rate and significantly reduced adverse outcomes including mortality, major bleeding, device embolization, and pericardial effusion.

RESUMO

Left atrial appendage closure (LAAC) reduces the risk of thromboembolic stroke in atrial fibrillation. Peri-device leak (PDL) after LAAC may affect the subsequent risk of thromboembolism. We conducted a systematic review and meta-analysis to evaluate the effect of PDL after LAAC. We searched PubMed/Medline, Embase, and Google Scholar for studies reporting outcomes of PDL after LAAC from inception through October 2022. The primary outcome was the composite of stroke, transient ischemic attack (TIA), or systemic embolism (SE). Secondary outcomes included all-cause and cardiovascular mortality, ischemic stroke, TIA, and device-related thrombus. Outcomes were pooled using random-effects models. We used I2 statistics to assess statistical heterogeneity; I2 >50% considered significant heterogeneity. This study included 54,279 patients from 11 studies (6 observational, 2 nonrandomized controlled trials [non-RCTs] primary results, 2 RCT post hoc analyses, and 1 analysis combining 2 RCTs data). PDL was associated with a significant increase in the composite outcome of stroke, TIA, or SE (odds ratio 1.63, 95% confidence interval 1.06 to 2.52, p = 0.03, I2 = 43%) as compared with cases with no PDL. There were no significant differences in all-cause or cardiovascular mortality, ischemic stroke, TIA, or device-related thrombus. In conclusion, PDL after LAAC is associated with an increased risk of thromboembolism (composite stroke, TIA, or SE) without impacting mortality.

RESUMO

Diagnosis of pharyngotonsillitis is challenging due to the wide range of symptoms and signs. Sudan Federal Ministry of Health and Sudanese Association of Paediatricians, along with Sudan Heart Society reached a consensus about the clinical prediction rule which aids in diagnosing and managing bacterial pharyngotonsillitis. This audit aimed to assess doctors' knowledge and practice regarding diagnosis and management of bacterial pharyngotonsillitis at Ribat Teaching Hospital, Khartoum, Sudan. This audit was done at Pediatric Department, Ribat Teaching Hospital, and data collection was done over 2 weeks either in the first or the second cycle. Inclusion criteria were children who presented at the emergency room and were diagnosed with acute pharyngotonsillitis. The criteria used in this audit were from Sudan guidelines for prevention, diagnosis and management of rheumatic heart disease. Regular training sessions were done between the first and second cycles. There were 19 patients in the first cycle, 17 of them (89.4%) were diagnosed clinically with bacterial pharyngotonsillitis, and 8 of these 17 (47%) were fitting the criteria. Regarding the management of bacterial pharyngotonsillitis, no patient was given the recommended antibiotics in the guidelines (0.00%). In the second cycle, there were 21 patients, of whom 11 patients were diagnosed clinically with bacterial pharyngotonsillitis (52%). Of those 11, 8 patients were fitting the criteria (72.7%), and the recommended antibiotics were given in 9 of them (82%). The current practice toward acute pharyngotonsillitis management revealed a lack of doctors' knowledge about local guidelines which can be improved by simple ways such as posters, lectures, and focused group discussions.
