Cardiovascular events caused by dyslipidemia are one of the leading causes of death in patients with Chronic Kidney Disease (CKD). Statins are the first line of treatment for patients with hyperlipidemia and in the treatment regimen for patients with CKD. Therefore, the introduction of Proprotein Convertase Subtilisin-Kexin type 9 inhibitors (PCSK9 inhibitors) is a viable and possibly effective treatment option for patients who, despite high doses of statins, struggle to lower their low-density lipoprotein cholesterol (LDL-C) levels. Our paper's objective is to explore the safety of these biological agents, particularly in patients with varying stages of impaired kidney function, and the correlating effectiveness in lowering their LDL-C levels, thereby reducing cardiovascular risks in these patients. We methodically retrieved relevant articles from PubMed, PubMed Central, Medline, and Google scholar in April 2022. We used the Medical Subject Heading (MeSH) Strategy and used the relevant keyword, then applied our inclusion and exclusion criteria; the initial search gave 10,542 results; with the removal of duplicates, irrelevant articles, and application of quality assessments done, we finally included 15 papers for our review with 37,188 patients. PCSK9 inhibitors are reliable, safe, and efficient therapy in lowering LDL-C levels in patients with CKD. However, its safety and efficacy in severe and end-stage kidney disease are grey, as other factors such as infections lead to morbidity and mortality. Future trials on chronic kidney disease and PCSK9 inhibitors should investigate the inhibitors' ability to improve kidney functions at all stages of kidney disease while lowering lipid levels and finally analyze the safety in patients with end-stage kidney disease.

Non-alcoholic fatty liver disease (NAFLD) represents one of the leading causes of chronic liver disease globally, perhaps because of the drastic increase in prevalence around the world during the last 20 years and continues growing. The disease starts from simple steatosis (NAFL) that can progress to non-alcoholic steatohepatitis (NASH) and, in some patients, progress to cirrhosis and hepatocellular carcinoma (HCC). The pathogenesis and pathophysiology of NAFLD are complex and involve different factors (genetic, metabolic, endocrinopathies, and others). One of the concerns that appeared in recent years is hypothyroidism-induced NAFLD. The pathogenesis is compound and not well understood, and an association between hypothyroidism and NAFLD remains controversial because of insufficient studies that can confirm it. More research is needed to determine the association between hypothyroidism and NAFLD and the underlying mechanisms. In this review, we will discuss a more in-depth analysis of the physiology of thyroid hormones (TH) as well as the pathophysiology of hypothyroidism-induced NAFLD and, based on the recent meta-analyses, the association of thyroid hormones and NAFLD.

Inflammatory bowel disease (IBD) is a globally rising chronic intestinal disease that affects individuals in many parts of the world. Immunosuppressive medications such as corticosteroids are used to manage flare-ups and to induce remission in IBD. Corticosteroids are said to cause several systemic symptoms, but they are also associated with drug-induced neuropsychiatric disorders. This article examines the existing data on psychiatric and cognitive effects associated with corticosteroid therapy in relation to IBD. Many studies have found that corticosteroids appear to cause mood disturbances such as mania, hypomania, depression, and cognitive problems in the first few weeks of therapy, but these effects are dose-dependent and often mild. The purpose of this literature review is to shed light on the impact corticosteroids can have on individuals' mental health, which will aid physicians in the future when treating patients with IBD. Healthcare professionals should advise patients of this risk and assess the need for intervention. While there is evidence that corticosteroids can elicit neuropsychiatric symptoms, more data on people with IBD who are on corticosteroid therapy is needed to determine the prevalence of glucocorticoid-induced mood changes in this population.

The objective of this systematic review and meta-analysis is to compare the postoperative outcomes of robotic and laparoscopic colorectal resection for colorectal malignancy. We performed a systematic review using a comprehensive search strategy on several electronic databases (PubMed, PubMed Central, Medline, and Google Scholar) in April 2022. Postoperative outcomes of robotic versus laparoscopic surgery for colorectal cancer were compared using 12 end points. Observational studies, randomized controlled trials, and nonrandomized clinical trials comparing robotic and laparoscopic resection for colorectal cancer were included. The statistical analysis was performed using the risk ratio (RR) for categorical variables and the standardized mean differences (SMD) for continuous variables. Sixteen studies involving 2,318 patients were included. The difference in length of hospital stay was significantly shorter with robotic access (SMD = -0.10, 95% CI = -0.19, -0.01, P = 0.04, I² = 0%). Regarding intra-abdominal abscesses, the analysis showed an advantage in favor of the robotic group, but the result was not statically significant (RR = 0.54, 95% CI = 0.28, 1.05, P = 0.07, I² = 0%). Mechanical obstruction was found to be higher in robotic group, favoring laparoscopic access, but was not significant (RR = 1.91, 95% CI = 0.95, 3.83, P = 0.07, I² = 0%). There was no difference in time to pass flatus and consume a soft diet. The rates of anastomotic leakage, ileus, wound infection, readmission, mortality, and incisional hernias were similar with both approaches. Robotic surgery for colorectal cancer is associated with a shorter hospital stay, with no differences in mortality and postoperative morbidity.

Coronavirus disease 2019 (COVID-19) has rapidly spread across the globe since December 2019. The spectrum of clinical manifestations of COVID-19 ranges from mild to life-threatening forms. Alteration of hepatic function in COVID-19 is multifactorial. The objective of this systematic review is to assess the relationship between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced hepatic dysfunction and the clinical outcome in patients infected with COVID-19. We methodically explored several electronic databases (PubMed, PubMed Central, MEDLINE, and Google Scholar) in April 2022 using focused words and terms of medical subject headings for appropriate studies. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for conducting our systematic review. Hepatic dysfunction was identified as elevation of liver function tests (LFTs) above the upper limit of normal. The clinical outcome was described as a combination of mortality, intensive care unit (ICU) transfer, and the need for mechanical ventilation (MV). The initial search yielded a total of 7187 studies. After elimination of duplicates, exclusion of studies based on irrelevant titles and abstracts, comprehensive analysis of full-text formats, and evaluation of quality, a total of 16 studies were eligible to be included in our systematic review. In the 16 selected studies, there were 23,962 patients. The SARS-CoV-2 virus can negatively affect several organ systems by interacting with specific receptors widely expressed in the human body. A multifactorial etiology of hepatic dysfunction is observed in COVID-19. SARS-CoV-2 infection is associated with abnormal LFTs. Significantly higher mortality, ICU admissions, and requirement for MV are associated with LFT alterations. For this reason, patients infected with COVID-19 must have their hepatic function closely monitored.

With the recent legalization of marijuana in several countries for recreational use, a controversial belief is spreading about it being "safe". In this systematic review, we decided to investigate this belief and present the adverse effects of marijuana and tobacco smoking on the cardiovascular system. We carried out an electronic search on databases including PubMed, PubMed Central, and Medline. Medical Subject Headings (MeSH) terms and different keywords were used for data collection. We included studies published in the last 10 years that were in English. All types of study subjects were accepted. Grey literature, books, case reports and case series, overlapping and duplicate studies, and studies older than 10 years were excluded. In this review, we included 18 studies, which we then separated into the "tobacco and cardiovascular disease" arm and the "cannabinoids and cardiovascular disease" arm. We had 11 and seven studies for each of the arms, respectively. The types of articles included in this review were traditional and systematic reviews and meta-analyses. After reviewing all the data included in this article, we found out that cannabinoid consumption has a more devastating effect on the cardiovascular system when compared to tobacco. The shocking fact was that in several cases, deadly adverse effects were observed in patients within a few hours after consumption or even during their first time using cannabinoids.
