No convincing modalities have been shown to completely prevent postdural puncture headache (PDPH) after accidental dural puncture (ADP) during obstetric epidural procedures. We aimed to evaluate the role of epidural administration of hydroxyethyl starch (HES) in preventing PDPH following ADP, regarding the prophylactic efficacy and side effects.

Messenger RNA (mRNA) vaccination was developed to mitigate the coronavirus disease 2019 pandemic. However, data on antibody kinetics and factors influencing these vaccines' immunogenicity are limited. We conducted a prospective study on healthy young adults who received two doses of the mRNA-1273 vaccine at 28-day intervals. After each dose, adverse events were prospectively evaluated, and blood samples were collected. The correlation between humoral immune response and reactogenicity after vaccination was determined. In 177 participants (19-55 years), the geometric mean titers of anti-S IgG antibody were 178.07 and 4409.61 U/mL, while those of 50% neutralizing titers were 479.95 and 2851.67 U/mL four weeks after the first and second vaccine doses, respectively. Anti-S IgG antibody titers were not associated with local reactogenicity but were higher in participants who experienced systemic adverse events (headache and muscle pain). Antipyretic use was an independent predictive factor of a robust anti-SARS-CoV-2 antibody response after receiving both vaccine doses. Systemic reactogenicity after the first dose influenced antibody response after the second dose. In conclusion, mRNA-1273 induced a robust antibody response in healthy young adults. Antipyretic use did not decrease the anti-SARS-CoV-2 antibody response after mRNA-1273 vaccination.

To identify and summarize data that describe the impact of effectively treating major depressive disorder (MDD) on the severity or risk of serious comorbidities. MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, and several congresses were searched. Searches included terms related to MDD, randomized controlled trials (RCTs), and physical comorbidities and were restricted to English-language publications. Searches were conducted in November 2019 for the previous 2 years for conference proceedings; no date restriction was applied to the database searches. Included studies were RCTs or meta-analyses that assessed depression therapies. Studies were required to report a statistically significant improvement in depression scores as well as the concurrent impact on comorbidities. A total of 1,997 articles were initially identified for screening. : Two investigators extracted data and assessed study quality. A total of 30 studies, including 24 RCTs (N = 6,333) and 6 meta/pooled analyses of RCTs, were included. Findings in several comorbidity categories were mixed; for example, in half (4 of 8) of the identified studies in people with cardiovascular disease and depression, individuals who received treatment leading to reduced depressive symptoms compared with a control arm also had a significantly decreased incidence of cardiovascular events or significantly improved cardiac disease symptom/severity scores compared with controls. Significant improvements in comorbid disease severity observed alongside improvements in depressive symptoms were also noted in studies of comorbid Parkinson's disease, multiple sclerosis, chronic pain and fibromyalgia, and chronic obstructive pulmonary disease. Effective treatment of MDD may lead to a reduction in the severity of certain serious comorbidities. These results highlight the importance of appropriate and timely treatment of MDD.

Hydroxyurea and low dose thalidomide are low-cost, easily accessible Hb F inducing agents that have been found to decrease transfusion dependency among transfusion-dependent thalassemia patients. However, these drugs have not much been explored in a randomized controlled setting. The objective of this study was to determine the efficacy and safety of hydroxyurea and low dose thalidomide in adult transfusion dependent β thalassemia. A total of 39 transfusion dependent β thalassemia patients were randomized into three arms: Arm A (Hydroxyurea 500 mg/day), Arm B (thalidomide 50 mg/day), and Control Arm. The primary outcome was rise in haemoglobin at 24-weeks from the baseline levels. The mean age of the cohort was 26.9 ± 4.7 years. Total 13 patients (33.3%) were splenectomised. The mean rise of haemoglobin at the end of 24 weeks was 0.18 ± 0.645 g/dl, 0.56 ± 1.343 g/dl, and - 0.31 ± 0.942 g/dl in Arm A, Arm B and control arm, respectively,  = 0.127. The mean volume of blood transfused per unit body weight in 24 weeks was significantly less in the thalidomide arm compared with the control arm ( = 0.035). Abdominal pain (Grade 1-2, 23.1%) and pruritus (Grade 1, 15.4%) were the main adverse events in hydroxyurea arm, whereas somnolence was the main side effect noted in the thalidomide arm (Grade 1-2, 78.3%). Single agent hydroxyurea or thalidomide is ineffective in increasing haemoglobin and decreasing transfusion burden among majority of the adult transfusion dependent thalassemia patients.

Post-COVID-19 syndrome is defined as continuous symptoms related to SARS-CoV-2 infection, which can persist for several weeks or months. Previous studies identified risk factors associated with post-COVID-19 syndrome, including female sex, hypertension, and allergic respiratory diseases. This study aims to investigate the frequency of this syndrome among Arabic patients.

Distoangular impacted teeth are considered challenging to remove due to their anatomic position. Proper tooth sectioning ensures the removal with minimal bone removal. This study is aimed to compare the outcome of 2 different tooth sectioning methods.

Hypertension coincides with the category of "vertigo" and/or "headache" on the basis clinical manifestations and traditional Chinese medicine (TCM) theory. Chai-Gui Decoction (CGD), which is in usage for relieving "vertigo" and/or "headache", had been demonstrated to be useful in ameliorating hypertension.

Chikungunya virus (CHIKV) is a pathogenic arbovirus spread by Aedes spp. mosquitos. CHIKV has a wide global prevalence and represents a significant health burden in affected populations. Symptoms of CHIKV infection include fever, rashes and debilitating joint and muscle pain, which can persist for several months to years in some patients. To date, there remains no vaccine or specific antiviral therapy against this important human pathogen. Based on our previously published structural and phenotypic analysis of the 5' region of the CHIKV genome, we designed a panel of locked nucleic acid oligonucleotides to bind structured RNA replication elements within the virus genome, which are essential for efficient CHIKV replication. Using electromobility shift assays, we confirmed the relative binding efficiencies of each LNA to target CHIKV genomic RNA. We then went on to demonstrate, using both sub-genomic replicon and infectious virus systems, that targeting individual RNA replication elements inhibits CHIKV genome replication and production of infectious virus. Time course assays demonstrated that LNAs can access the CHIKV replication complex and virus genome, during active virus replication. For the first time, these findings show that functional RNA elements can be specifically targeted during the CHIKV lifecycle and consequently represent potential novel antiviral targets.

A patient in their 50s presented with postcoital severe headache. Computed tomography revealed a subarachnoid haemorrhage but also a subdural hematoma at the left convexity. CT angiography revealed a large irregular anterior communicating artery aneurysm but also cortical serpiginous vessels suggestive of a vascular malformation adjacent to the subdural hematoma in the left convexity. DSA confirmed the ruptured aneurysm but also revealed a Borden 3 type dural arteriovenous fistula on the left convexity. The fistula had arterial supply mostly from middle meningeal artery branches and venous drainage directly to a left cortical vein adjacent to superior sagittal sinus. Ruptured aneurysm was treated with coiling. The ruptured fistula was treated in the same session with transarterial Onyx embolization. Patient had a favourable outcome. Our case is an important reminder for all clinicians treating patients with intracranial hemorrhages on the necessity of fully reviewing all available preoperative imaging.

Clinical guidelines recommend exercise as a core treatment for knee or hip osteoarthritis (OA). However, how its analgesic effect compares to analgesics, for example, oral non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol-the most commonly used analgesics for OA, remains unknown.
