Meta-Analysis
Effectiveness and safety of the combination of sodium-glucose transport protein 2 inhibitors and glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes mellitus: a systematic review and meta-analysis of observational studies.
BACKGROUND
Randomized controlled trials and real-world studies suggest that combination therapy with sodium-glucose transport protein 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) is associated with improvement in fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), systolic blood pressure (SBP), body mass index (BMI), and total cholesterol levels. However, a systematic review of available real-world evidence may facilitate clinical decision-making in the real-world scenario. This meta-analysis assessed the safety and effectiveness of combinations of SGLT2is + GLP-1RAs with a focus on their cardioprotective effects along with glucose-lowering ability in patients with type 2 diabetes mellitus (T2DM) in a real-world setting.
METHODS
Electronic searches were performed in the PubMed/MEDLINE, PROQuest, Scopus, CINAHL, and Google Scholar databases. Qualitative analyses and meta-analyses were performed using the Joanna Briggs Institute SUMARI software package and Review Manager v5.4, respectively.
RESULTS
The initial database search yielded 1445 articles; of these, 13 were included in this study. The analyses indicated that SGLT2is + GLP-1RAs combinations were associated with significantly lower all-cause mortality when compared with individual therapies (odds ratio [95% confidence interval [CI] 0.49 [0.41, 0.60]; p < 0.00001). Significant reductions in BMI (- 1.71 [- 2.74, - 0.67]; p = 0.001), SBP (- 6.35 [- 10.17, - 2.53]; p = 0.001), HbA1c levels (- 1.48 [- 1.75, - 1.21]; p < 0.00001), and FPG (- 2.27 [- 2.78, - 1.76]; p < 0.00001) were associated with the simultaneous administration of the combination. Changes in total cholesterol levels and differences between simultaneous and sequential combination therapies for this outcome were not significant.
CONCLUSION
This systematic review and meta-analysis based on real-world data suggests that the combination of SGLT2is + GLP-1RAs is associated with lower all-cause mortality and favorable improvements in cardiovascular, renal, and glycemic measurements. The findings drive a call-to-action to incorporate this combination early and simultaneously in managing T2DM patients and achieve potential cardiovascular benefits and renal protection.

Review
INTRODUCTION
TBIs contribute in over one-third of injury-related deaths with mortality rates as high as 50% in trauma centers serving the most severe TBI. The effect of TBI on mortality is about 10% across all ages. Amantadine hydrochloride is one of the most commonly prescribed medications for patients undergoing inpatient neurorehabilitation who have disorders of consciousness. It is a dopamine (DA) receptor agonist and a N-Methyl-D-aspartate (NMDA) receptor antagonist via dopamine release and dopamine reuptake inhibition. The current study will synthesize the current available evidence and show the effect of Amantadine in functional improvement after TBI.
RESEARCH QUESTION
Does Amantadine have an effect on functional improvement of TBI patients?
MATERIAL AND METHODS
This systematic review included all randomized placebo-controlled trials that compare the use of Amantadine versus placebo for functional improvement of patients after TBI. Outcome measures included DRS, GCS and/or GOS scores.
RESULTS
Three studies with a total of 281 patients were included in the quantitative analyses. GRADE assessments show that there was a high certainty of evidence for functional improvement in terms of DRS scores.
DISCUSSION AND CONCLUSION
Evidence of this review show that the use of Amantadine may have a beneficial effect on functional outcome in moderate to severe traumatic brain injuries among adult patients. Given the still-limited body of knowledge, more relevant studies must be made exploring the impact of Amantadine therapies on promoting functional recovery within the brain injury rehabilitation care continuum, with the goals of achieving larger sample sizes and establishing the early- or later-treatment beneficial effects.

Review
According to the World Health Organization (WHO), the prevalence of type 2 diabetes mellitus (T2DM) and obesity has increased globally over the past 50 years, affecting over 500 million adults worldwide in 2023. A novel class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists have emerged as a beacon of hope in treating the pandemic of diabetes and obesity. This analysis' objective was to draw comparisons of how these medications reduce cardiovascular outcomes. The review revealed unique differences in GLP-1s, highlighting some of their strengths and weaknesses and which populations they can cater to preferentially. Even though all drugs in question of this review are proven to be efficacious for diabetes and obesity, differences in their cardiovascular safety profiles and efficacy were noted. The analysis recognized the potential of drugs like semaglutide and tirzepatide, as leaders in the space. Although this current assessment of where GLP-1 receptor agonists stand in regard to cardiovascular outcomes may still be premature, the space is extremely active, and there are trials that are highly anticipated to transform the landscape of diabetes and obesity management in patients with more established cardiovascular comorbidities in the near future.

Meta-Analysis
To test the hypothesis that genetic and pharmacological modulation of the classical cannabinoid type 1 (CB) and 2 (CB) receptors attenuate cancer-induced bone pain, we searched Medline, Web of Science and Scopus for relevant skeletal and non-skeletal cancer studies from inception to July 28, 2022. We identified 29 animal and 35 human studies. In mice, a meta-analysis of pooled studies showed that treatment of osteolysis-bearing males with the endocannabinoids AEA and 2-AG (mean difference [MD] - 24.83, 95% confidence interval [CI] - 34.89, - 14.76, p < 0.00001) or the synthetic cannabinoid (CB) agonists ACPA, WIN55,212-2, CP55,940 (CB-non-selective) and AM1241 (CB-selective) (MD - 28.73, CI - 45.43, - 12.02, p = 0.0008) are associated with significant reduction in paw withdrawal frequency. Consistently, the synthetic agonists AM1241 and JWH015 (CB-selective) increased paw withdrawal threshold (MD 0.89, CI 0.79, 0.99, p < 0.00001), and ACEA (CB-selective), AM1241 and JWH015 (CB-selective) reduced spontaneous flinches (MD - 4.85, CI - 6.74, - 2.96, p < 0. 00001) in osteolysis-bearing male mice. In rats, significant increase in paw withdrawal threshold is associated with the administration of ACEA and WIN55,212-2 (CB-non-selective), JWH015 and AM1241 (CB-selective) in osteolysis-bearing females (MD 8.18, CI 6.14, 10.21, p < 0.00001), and treatment with AM1241 (CB-selective) increased paw withdrawal thermal latency in males (mean difference [MD]: 3.94, CI 2.13, 5.75, p < 0.0001), confirming the analgesic capabilities of CB ligands in rodents. In human, treatment of cancer patients with medical cannabis (standardized MD - 0.19, CI - 0.35, - 0.02, p = 0.03) and the plant-derived delta-9-THC (20 mg) (MD 3.29, CI 2.24, 4.33, p < 0.00001) or its synthetic derivative NIB (4 mg) (MD 2.55, CI 1.58, 3.51, p < 0.00001) are associated with reduction in pain intensity. Bioinformatics validation of KEGG, GO and MPO pathway, function and process enrichment analysis of mouse, rat and human data revealed that CB and CB receptors are enriched in a cocktail of nociceptive and sensory perception, inflammatory, immune-modulatory, and cancer pathways. Thus, we cautiously conclude that pharmacological modulators of CB receptors show promise in the treatment of cancer-induced bone pain, however further assessment of their effects on bone pain in genetically engineered animal models and cancer patients is warranted.

Review
OBJECTIVE
Systematically review evidence on using GLP-1RAs for reducing BEB in BED and BN.
METHODS
Comprehensive literature search (PubMed and Google Scholar) conducted for studies evaluating GLP-1Ras for BEB. Extracted data on study characteristics, efficacy, and safety.
RESULTS
Studies show that GLP-1RAs (liraglutide and dulaglutide) reduce BE frequency and comorbidities in addition to favorable psychiatric side effect profile compared to current options. However, large-scale, blinded placebo-controlled trials are lacking.
CONCLUSION
Early findings suggest promising effects of GLP-1RAs on BEB. However, rigorous clinical trials are needed to firmly establish efficacy, dosing, safety, and comparative effectiveness before considering GLP-1RAs a viable novel approach.

Review
Polycystic ovary syndrome is a common reproductive endocrine condition that affects women of fertile age and is characterized by three main features, including hyperandrogenism, chronic anovulation, and polycystic ovaries. In addition, half of women with polycystic ovary syndrome have insulin resistance, and obesity or overweight, type 2 diabetes, hypertension, and hyperlipidemia are the most common metabolic abnormalities affecting (30%) women with polycystic ovary syndrome. Weight loss is regarded as the first-line treatment as it can potentially improve polycystic ovary syndrome parameters (androgen levels, menstrual cyclicity, lipid and glucose metabolism). However, achieving and maintaining weight loss can be challenging, and pharmacological agents could be essential to achieve optimal glycemic control and improve the endocrine disturbance associated with polycystic ovary syndrome. Glucagon-like peptide-1 receptor agonist has been demonstrated as monotherapy or in combination with metformin for managing obesity and insulin resistance associated with polycystic ovary syndrome. Yet, its effect on endocrine and metabolic parameters remains elusive, and further research is needed to close the gap. The aim is to evaluate the efficacy of glucagon-like peptide-1 receptor agonist monotherapy and/or a combined treatment between glucagon-like peptide-1 receptor agonist and metformin for improving anthropometric measurements, endocrine and metabolic parameters in lean and obese women with polycystic ovary syndrome. A systematic review of longitudinal cohort studies was conducted across databases including Ovid Medline, PubMed Central, and Cochrane Library between 2015 and 2022. Eligible studies included participants with polycystic ovary syndrome diagnosed according to the 2003 Rotterdam or the 1990 National Institutes of Health criteria. A total of eight studies including 486 patients with polycystic ovary syndrome were analyzed. The mean age was between 18 and 45 years with mean follow-up period between 12 and 32 weeks. In all these studies, results were comparable for the reduction in body mass index, waist circumference, fat mass, and visceral fat mass; however, it was more in combination therapy versus comparator. In conclusion, glucagon-like peptide-1 receptor agonists effectively reduce body weight and improve some of the endocrine and metabolic parameters of polycystic ovary syndrome. A combined treatment with glucagon-like peptide-1 receptor agonist and metformin had significant effects on weight loss and favorable results on endocrine and metabolic parameters, yet further research is needed to discover the long-term safety of combined therapy in women diagnosed with polycystic ovary syndrome and obesity or overweight.

Meta-Analysis
BACKGROUND
Overweight and obesity are increasing global public health problems. Mazdutide is a new dual agonist drug that can potentially reduce weight and blood glucose levels simultaneously. However, the synthesis of evidence on the efficacy and safety of this drug is scarce. Therefore, this study aimed to synthesize evidence on the efficacy and safety of Mazdutide compared to placebo on weight reduction among adults with and without diabetes.
METHODS
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). Data were retrieved from six electronic databases: PubMed, Web of Science, Scopus, Cochrane Library, ClinicalTrial.gov, and Google Scholar, and manually searched from the included references. The data were synthesized using a random effect model. This analysis was performed in the R programming language using the Meta package.
RESULTS
A total of seven RCTs involving 680 participants were included in this study. Mazdutide was more effective in reducing body weight (mean difference [MD]= -6.22%, 95% confidence interval [CI]: -8.02% to -4.41%, I = 90.0%), systolic blood pressure (MD = -7.57 mmHg, 95% CI: -11.17 to -3.98 mmHg, I = 46%), diastolic blood pressure (MD = -2.98 mmHg, 95% CI: -5.74 to -0.22 mmHg, I = 56%), total cholesterol (MD = -16.82%, 95% CI: -24.52 to -9.13%, I = 61%), triglycerides (MD = -43.29%, 95% CI: -61.57 to -25.01%, I = 68%), low-density lipoprotein (MD= -17.07%, 95% CI: -25.54 to -8.60%, I = 53%), and high-density lipoprotein (MD = -7.54%, 95% CI: -11.26 to -3.83%, I = 0%) than placebo. Mazdutide was associated with reduced hemoglobin A1c (HbA1c) and fasting plasma glucose in participants with type 2 diabetes. In the subgroup and meta-regression analyses, weight reduction was more significant in non-diabetics compared to diabetics, and in those who received a longer treatment duration (24 weeks) than in those on shorter durations (12-20 weeks). Participants who received Mazdutide had a higher risk of transient mild or moderate gastrointestinal side effects.
CONCLUSION
Mazdutite appears to be effective in weight reduction among patients with and without diabetes, and it has an advantage over other associated comorbidities. However, it was associated with mild or moderate gastrointestinal side effects.

Review
Parkinson's disease (PD) is a terminal, debilitating neurodegenerative disorder typically affecting individuals over 60. It is associated with various conditions that drastically affect the patient's quality of life (QoL). Although there is no cure for PD, its symptoms can be significantly improved and even resolved through different treatments. Mainstay treatments for PD include levodopa combined with carbidopa, dopamine agonists, and even deep brain stimulation (DBS) of the subthalamic nucleus. New treatment methods have emerged, such as botulinum toxin (BoNT), which further improve symptoms and, thus, the QoL of patients with PD. Botulinum toxin is a potent neurotoxin produced by that typically causes descending paralysis by suppressing acetylcholine secretion. Serotypes used to treat various disorders include serotype A (BoNT-A) and serotype B (BoNT-B). This paper aims to evaluate the outcomes of BoNT injection on different symptoms associated with PD. An extensive review using PubMed, ScienceDirect, and ProQuest articles concerning 'botulinum toxin and Parkinson's disease' was done per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, resulting in 23,803 articles. After applying strict inclusion and exclusion criteria, the total number of articles was finally 41. The results showed that movement disorders were a common occurrence in PD, consisting of tremors, dystonia, and freezing of gait (FOG), with tremors being the most common symptom. Tremors and dystonia were significantly improved following BoNT-A, correlating with significant improvements in various scales subjectively and objectively evaluating the symptoms and QoL. In contrast, FOG was not significantly improved by either BoNT-A or BoNT-B. Pain is associated with movement disorders such as PD and was the primary indication for the administration of BoNT; studies found pain and QoL were significantly improved following BoNT injection. Quality of life can also be affected by sialorrhea and overactive bladder, which often occur as the disease progresses. Injections of BoNT-A and BoNT-B were shown to significantly improve saliva production, flow rate, drooling frequency, voiding frequency, and urinary urge incontinence. Across all studies analyzed, it is evident that BoNT may have a significant effect on improving the QoL of patients suffering from PD. While research continues to find a cure or stop the progression of PD, it remains critical to continue focusing on improving patients' QoL. Future research should evaluate whether BoNT can be used to successfully treat other symptoms of PD, such as epiphora or constipation.

Review
BACKGROUND
Orforglipron is a novel once-daily oral non-peptide glucagon-like peptide-1 receptor agonist with several recently published randomized controlled trials (RCTs) evaluating its role in diabetes and obesity. No meta-analysis has analyzed the efficacy and safety of orforglipron; this meta-analysis aimed to address this knowledge gap.
METHODS
A systematic search was conducted in electronic databases to identify RCTs that included individuals with obesity who were administered orforglipron and compared to either a placebo or an active comparator. The primary outcome of interest was the percent change in body weight.
RESULTS
From 12 initially screened articles, data from three RCTs involving 774 people were analyzed with a follow-up duration of up to 36 weeks. Compared to placebo, patients receiving orforglipron 12 mg/day (mean difference (MD), MD -5.48%, 95% CI [-7.64, -3.33], < 0.01), 24 mg/day (MD -8.51%, 95% confidence interval (CI) [-9.88, -7.14], < 0.01), 36 mg/day (MD -8.84%, 95% CI [-11.68, -6.00], < 0.01) and 45 mg/day (MD -8.24%, 95% CI [-12.84, -3.63], < 0.01) had a significantly greater percent reduction in body weight. The percentage of patients being able to achieve >15% weight loss from baseline was significantly higher with orforglipron 24 mg/day [Odds ratio (OR) 21.90 (95% CI [4.06, 118.15], = 0.0003), 36 mg/day (OR 17.43, 95% CI [3.18, 95.66], = 0.001) and 45 mg/day (OR 23.17, 95% CI [4.37, 123.03], = 0.0002). Total but not severe adverse events were significantly higher with all the doses of orforglipron compared to placebo, with the hazard ratios being higher with higher doses. Gastrointestinal side-effects were predominant side effects, being dose-dependent, with nausea, vomiting, constipation, and gastroesophageal reflux being the predominant ones.
CONCLUSION
Orforglipron at 24-45 mg/day doses is an effective weight loss medication. The efficacy versus side effect profile suggests that 24-36 mg/day is the most optimal dose for orforglipron as an anti-obesity medicine.

BACKGROUND
Evidence supporting glucagon-like peptide-1 receptor agonists (GLP-1RAs) in kidney transplant recipients (KTRs) remains scarce. This systematic review and meta-analysis aims to evaluate the safety and efficacy of GLP-1RAs in this population.
METHODS
A comprehensive literature search was conducted in the MEDLINE, Embase and Cochrane databases from inception through May 2023. Clinical trials and observational studies that reported on the safety or efficacy outcomes of GLP-1RAs in adult KTRs were included. Kidney graft function, glycaemic and metabolic parameters, weight, cardiovascular outcomes and adverse events were evaluated. Outcome measures used for analysis included pooled odds ratios (ORs) with 95% confidence intervals (CIs) for dichotomous outcomes and standardized mean difference (SMD) or mean difference (MD) with 95% CI for continuous outcomes. The protocol was registered in the International Prospective Register of Systematic Reviews (CRD 42023426190).
RESULTS
Nine cohort studies with a total of 338 KTRs were included. The median follow-up was 12 months (interquartile range 6-23). While treatment with GLP-1RAs did not yield a significant change in estimated glomerular filtration rate [SMD -0.07 ml/min/1.73 m (95% CI -0.64-0.50)] or creatinine [SMD -0.08 mg/dl (95% CI -0.44-0.28)], they were associated with a significant decrease in urine protein:creatinine ratio [SMD -0.47 (95% CI -0.77 to -0.18)] and haemoglobin A1c levels [MD -0.85% (95% CI -1.41 to -0.28)]. Total daily insulin dose, weight and body mass index also decreased significantly. Tacrolimus levels remained stable [MD -0.43 ng/ml (95% CI -0.99 to 0.13)]. Side effects were primarily nausea and vomiting (17.6%), diarrhoea (7.6%) and injection site pain (5.4%).
CONCLUSIONS
GLP-1RAs are effective in reducing proteinuria, improving glycaemic control and supporting weight loss in KTRs, without altering tacrolimus levels. Gastrointestinal symptoms are the main side effects.
