BackgroundClinical trials have evaluated the efficacy of intravenous mesenchymal stem cells (MSCs) for acute and subacute ischemic stroke. Therefore, we conducted this meta-analysis to investigate the efficacy and safety of intravenous MSC treatments compared to placebo for acute and subacute ischemic stroke patients.MethodsWe searched PubMed, SCOPUS, Web of Science, and Cochrane CENTRAL for randomized controlled trials evaluating any clinical trials of intravenous MSCs for acute and subacute ischemic stroke patients. The efficacy outcomes of this study were the rates of improvement in National Institutes of Health Stroke Scale (NIHSS) scores, good scores on the modified Rankin Scale (mRS), and Barthel Index (BI) scores, while the safety outcomes were the rates of mortality and stroke recurrence. We compared intravenous MSC and placebo treatments on a fixed-effect meta-analysis model in R software.ResultsFour randomized controlled studies involving 97 patients were included in the analysis. In the meta-analysis, MSC treatments were superior to placebo treatments in good mRS (MD −0.95, 95% CI [−1.39, −0.52]) or BI (MD 21.36, 95% CI [9.96, 32.75]) scores, and MSC treatments were not superior to placebo treatments in the rate of improvement of the NIHSS scores (MD −1.81, 95% CI [−4.123, 0.494]). MSCs were associated with neither decreased mortality nor stroke recurrence (risk ratio 0.58 and 0.59, respectively; p-value = 0.51 and p-value = 0.533, respectively).ConclusionFor patients with acute and subacute ischemic stroke who are eligible for further damage to neural tissue, MSCs achieve high efficacy and acceptable safety.Systematic review registrationProspero, unique ID: CRD42023457655.

Objective: This study provides histological evidence of the combined effects of L-Carnitine, and Coenzyme Q10 on gliosis and anhedonia in a rat model of multiple sclerosis (MS). Methods: Fifty male Sprague Dawley rats were randomly divided into 5 groups of 10 rats each. Group 1 was the control group. The rest of the groups were disease models and were given 0.2% cuprizone w/w to induce MS. After 4 weeks, Group 3 started receiving L-Carnitine, Group 4 was given Coenzyme Q10, and Group 5 received both, while cuprizone poisoning continued. After 12 weeks sucrose preference test and tail suspension test were performed for anhedonia. Rats were euthanized and brains were dissected, and assessed for astrocytes, oligodendrocytes, and microglial count. Results: A significant increase in oligodendrocyte count, while a reduction in astrocyte and microglial count was seen in the synergistic group (p < 0.05). Synergism could not be proved in anhedonia. Conclusion: The combination of Coenzyme Q10 and L-Carnitine has a synergistic effect in controlling gliosis in a rat model of MS, but synergism could not be demonstrated on anhedonia.

Purpose: Palliative care is regarded as fundamental to human dignity and falls under the definition of basic human rights. One considerable community of color whose needs are poorly understood consists of Asian Americans, including distinct priorities, expectations, and decision-making processes by diverse subgroups. The purpose of this work was to understand whether and to what extent unique considerations are understood among Asian American subgroups. Method: A scoping review was conducted among major scientific and academic databases. Broad search terms surrounding end-of-life care were combined with individual racial and ethnic identifiers encompassing Asian American subgroups. Results: Twenty-two articles met inclusion criteria and reflected diverse arrays of worldviews surrounding access to, utilization of, and desired outcomes from palliative care. Most articles focused on social orientations prioritizing family in disease disclosure and avenues of interventions sought with distinct patterns among subgroups. Discussion/Conclusion: A human rights framework emphasizing palliative and other end-of-life approaches to care may be inadequate to address unique considerations among diverse Asian American subgroups. Theorists and practitioners should incorporate practices of collectivist orientations and family contexts commonly found among these diverse communities.

Online learning has grown productive and vital for delivering asynchronous instruction to undergraduate medical students. We explored the factors that affect the learning of undergraduate medical students in an online asynchronous Forensic Medicine course through focus group discussions. These factors were identified in three components of theoretical framework: learner, design, and environment. The promoting factors in the learner component were regulation of learning, internal motivation, metacognition, interaction with peers, and social interaction. Hampering factors were poor self-regulation, losing motivation, and less use of discussion forums. In the environment component students' engagement, external motivation, and lack of physical interaction hampered the learning. In design: course content, links, extra material, pre-recorded lectures, assessment, time limitation, and flexibility promoted the learning, while lack of training in asynchronous mode, losing motivation, loss of attention, and less interaction hampered learning. These identified factors will assist online educators and instructors in designing better online asynchronous courses. [ABSTRACT FROM AUTHOR]

Background and Aims: The polycystic ovarian syndrome is a menacing metabolic condition with high prevalence rate in Asian countries involving women of reproductive age. This study was commenced to assess favorable effects of Lycopene--a dietary component in letrozole-induced PCOS rat model. Materials and Methods: Fifty adult female Sprague Dawley rats were divided into five groups, ten rats each for a study of 5weeks. Control group A was given standard rat diet. Rats of experimental group B were given 1mg/kg of Letrozole to induce PCO model. Group C was given 1mg/kg of letrozole+15mg/kg/day of lycopene. Group D was given 1mg/kg of letrozole+ 500 mg/kg/day metformin. Group E was given 1mg/kg of letrozole +combination of Lycopene and metformin together. Relative body weight was taken on the day1, day21 and end of experiment. Antioxidant activity was tested using CAT, SOD and MDA. Ovaries were removed for H&E staining and studied under light microscopy. Statical analysis was carried out for result interpretations. Results: The results showed, reduced rat weight by use of Lycopene. Histological architecture of ovary showed better count of secondary and graafian follicles towards normal values which was quite reduced in group B proved by significant p-value<0.001. While raised number of atretic follicles in group B 6±1.6 was reduced to 3±0.9, 4±0.6, 4±0.7 in group C, D &E respectively. Overall improvement in distorted/cystic ovaries was noted by treatment therapy, evident by significant p-value. Group B showed mean count of cyst 7±1.0, which was brought to 2±0.5, 3±0.8, 2±0.7 in groups C, D &E. Elevated Oxidative markers (ROS) were also reduced. Conclusion: Dietary intake Lycopene can ameliorate histological and oxidative damage in polycystic ovaries. [ABSTRACT FROM AUTHOR]

Background: Helicobacter pylori (H. pylori) is a gram-negative bacterium which usually resides in the mucoid lining of the stomach and may cause different gastric pathologies e.g., Gastritis, peptic ulcer disease, adenocarcinoma of the gastric system and mucoid associated lymphoma (MALT). The Objective was to compare the effect of 7-days Vonoprazan based triple therapy and 14-days Esomeprazole based triple therapy on eradication rate, compliance and cost effectiveness in Helicobacter pylori infected patients. Methods: This clinical trial was performed in the Department of Pharmacology Army Medical College, National University of Medical Sciences (NUMS) in collaboration with the Gastroenterology Department, Pak Emirates Military Hospital (PEMH) Rawalpindi from December 2022 to March 2023. A total of one hundred and twenty-two patients with dyspepsia symptoms and yielding lab results positive for Helicobacter pylori by stool antigen test were enrolled in the study. They were randomly allocated into two groups. The Esomeprazole group received 14 days of triple therapy orally with Esomeprazole 20 mg twice a day; Amoxicillin 1000 mg twice a day; and Levofloxacin 500 mg one time a day. The comparative Vonoprazan group was given 7-days triple therapy orally with Vonoprazan 20 mg twice a day; Amoxicillin 1000 mg twice a day; and Levofloxacin 500 mg one time a day. Eradication success was evaluated by stool antigen test four weeks later, as counted from the start of treatment. compliance and cost-effectiveness of both therapies were also assessed. Results: The eradication rate was (95.1%) in the Vonoprazan group with 58 out of 61 patients negative for H. pylori and (93.1%) in Esomeprazole group with 54 patients out of 58 yielding a negative result demonstrating p-value of 0.64. Compliance was 95.0% in the Esomeprazole group with p-value of 0.07. Cost effective ratio for Vonoprazan triple therapy was lower (731.8PKR) than the Esomeprazole group. Conclusion: One two-week Vonoprazan regimen demonstrated improved eradication rate, good compliance, and better tolerability in patients with less cost and a half duration of treatment in comparison with two weeks Esomeprazole regimen, attesting that one week Vonoprazan therapy is more cost efficacious in producing better results.

Background: Sodium-glucose co-transporter 2 inhibitors (SGLT2i) is a new class of medication for the treatment of type 2 diabetes mellitus. Additionally, they have been found to have beneficial effects on heart failure outcomes, convincingly reducing the morbidity and mortality in heart failure. Although the medical data indicates SGLT2i to be safe and cardio-protective, very little attention has been given to the impact of these agents on electrolyte balance particularly in acute heart failure (AHF). We aimed to evaluate the effect of SGLT2i, and dapagliflozin on serum sodium, potassium and creatinine in AHF. Methods: Overall, 160 adult patients of either gender, admitted with AHF were selected for the study. Selected individuals were randomly assigned to receive dapagliflozin 10 mg orally added to standard medical treatment (n=80) or were in reception of standard medical therapy only (n=80). Serum electrolytes and serum creatinine were collected on admission and day 7 or on discharge whichever happened earlier. Results: The mean level of serum electrolytes displayed insignificant differences among both groups on admission. The mean level of serum potassium was higher in the dapagliflozin group compared with the control group (p<0.001) on day 7/discharge. Mean serum sodium level was comparable and showed significant differences between the two groups following treatment (pvalue= 0.021). Significant higher levels of serum creatinine were observed following treatment in both groups. However, on intergroup comparison, they were statistically insignificant. Conclusion: Dapagliflozin is an effective treatment of heart failure and is not associated with deterioration of serum electrolyte levels and renal functioning when used as add-on therapy in AHF.

Objective: To evaluate the influence of dapagliflozin on renal functions and diuretics use in patients with acute heart failure (AHF). Methods: This comparative analytical study was conducted at Armed Forces Institute of Cardiology, Rawalpindi from July 2022 to November 2022. Patients were distributed equally in two groups i.e. Dapagliflozin and Conventional Groups, where patients received dapagliflozin added to conventional therapy for AHF and, only conventional therapy for AHF respectively. Estimated glomerular filtration rate (eGFR), serum creatinine were measured and compared on admission, after 48 hours and on discharge. Weight loss during hospitalization, daily dose of furosemide and length of hospital stay was also recorded. Quantitative parameters were analyzed using t-test or Mann Whitney U test accordingly. Results: There were no significant baseline differences in renal functions. A modest decline in eGFR was observed in both groups after 48 hours. However, the variation in values of eGFR remained similar among both groups after 48 hours (p-value 0.365) and on discharge (p-value 0.768). Whereas, patients subjected to dapagliflozin treatment exhibited a more profound diuretic response expressed as greater weight loss (p-value < 0.001), achieved at comparatively lower doses of loop diuretics. Moreover, they also had a shorter duration of hospital stay (six vs eight days, p-value <0.001). Conclusion: Institution of dapagliflozin did not cause any significant deterioration of renal functions, whereas; it was associated with improved diuretic response as depicted by more pronounced weight loss at comparatively lower doses of loop diuretics.

Background: Shivering is one of the most common adverse outcomes associated with the administration of spinal anaesthesia, which, when clinically relevant, leads to numerous detrimental effects on the human body. Hence, its management becomes imperative. Meperidine, an opioid analgesic, is the drug of choice for this condition. However, the use of meperidine is controversial, as it carries the devastating adverse effect of respiratory depression. We explored the role of granisetron, a 5HT3 antagonist and a commonly used antiemetic premedication, in minimising the incidence of post-spinal shivering and decreasing the use of meperidine as a rescue drug. Methods: Overall, 160 parturient patients, between the ages 18-50, undergoing uncomplicated, elective caesarean section, were enrolled in the study, and randomized into two groups with 80 participants each: Group A received 3ml of normal saline, and Group B was administered 3 mg granisetron, 15 minutes before spinal anaesthesia institution. Incidence of clinically relevant shivering (score of 3 or more) was noted, and it was recorded whether meperidine was used or not. Results: 67.5% of participants in Group A, and 32.5% of patients in Group B, experienced clinically relevant shivering, with 62.5% of patients in Group A and 28.75% in Group B warranting the use of meperidine. There was a statistically significant difference between the two groups in terms of incidence of clinically relevant shivering, and meperidine consumption (p-value <0.001). Conclusion: Premedication with 3 mg granisetron effectively attenuates the occurrence of post-spinal shivering and, hence, lowers the requirement of meperidine as rescue medication.

Background: Abstraction of wisdom teeth or impacted third molar under local anaesthesia is one of the most frequent interventions by an oral and maxillofacial surgeon. The abstraction of the third molar is usually followed by the release of liberation and consequent trismus, pain, and swelling due to the area of the third molar being highly vascularized and rich in loose connective tissue. Objective of the study was to evaluate the anti-inflammatory effect of ascorbic acid following surgical extraction of the third molar. Methods: The current study was carried out Armed Forces Institute of Dentistry, Rawalpindi, from October to December 2022. This was a cross-sectional observational study. Fifty participants who required surgical extraction of the impacted third molar were included in the study via non-probability purposive sampling and were segregated equally into two groups, i.e., Group A and Group B, comprising twenty-five participants in each group. Group A received amoxicillin with clavulanic acid (625 mg) thrice a day and metronidazole (400 mg) twice daily. In comparison, Group B received amoxicillin with clavulanic acid (625 mg) thrice daily, ascorbic acid (500 mg) twice daily, and metronidazole (400 mg) twice daily. Both groups received naproxen sodium as per requirement (550 mg). Pain, facial swelling, and C reactive protein concentration were evaluated until the 7th postoperative day. Results: There was a reduction in pain and facial swelling in both groups, but in the ascorbic acid group, there was more reduction in pain and facial swelling compared to the control group. However, the difference between the two groups in reducing pain and facial swelling was statistically significant (p<0.01). There was a reduction in CRP in both groups, but in the ascorbic acid group, there was more reduction in CRP 2.35 (1.60-5.30) compared to the control group 2.6 (0.86-5.03). However, the difference between the two groups in reducing C reactive protein concentration was statistically insignificant (p>0.05). Conclusion: Our study concluded that ascorbic acid significantly reduced inflammation and C reactive protein, so ascorbic acid should be used as an adjuvant supplement with other conventional drugs.
