RESUMO

Background: The safety and efficacy of enhanced recovery after surgery (ERAS) following elective gastrectomy for gastric cancer in patients >80 years of age are not well described. The aim of this study was to explore whether an ERAS protocol following gastrectomy in this age group can be safely implemented and reduce postoperative length of stay. Methods: A retrospective, single-center analysis was performed. All patients >80 years of age with gastric cancer undergoing elective subtotal and total gastrectomy between January 2010 and December 2021 were identified. With the implementation of an ERAS protocol in January 2016, patients treated beforehand were allocated to Group A (pre-ERAS) and Group B (ERAS). The length of stay, incidence of postoperative complications and representation/readmission to the hospital were compared between the groups. Results: Of the 221 patients identified, 56 met the inclusion criteria with 22 patients (39.3%) allocated to Group A and 34 patients (60.7%) to Group B. There were no differences with regard to the type of resection and surgical approach. Length of stay was shorter in Group B (5 days, range 2-27 versus 10 days, 3-109, P = .040). A trend toward more discharges by postoperative day 3 was noted among patients in Group B (7/34, 20.6% versus 2/22, 9.1%, P = .253). There were no differences in the incidence of postoperative complications or readmission hospital between the groups. Conclusion: Among patients >80 years of age, ERAS following gastrectomy for cancer is associated with a reduced length of stay and can be safely implemented.

RESUMO

BACKGROUND: With increases in cannabis use and potency, there is a need to improve our understanding of the impact of use on cognitive function. Previous research indicates long-term cannabis use may have a negative effect on executive function. Few studies have examined persistence of it in protracted abstinence, and there is limited evidence of predictors of worse cognitive function in current and former users. In this study, we aim to evaluate the associations between cannabis use status (current, former, and never use) and self-report cognition. Further, we investigate if cannabis use characteristics predict self-report cognitive function. METHODS: Cross-sectional cannabis use data from the National Epidemiological Survey on Alcohol and Related Conditions-III (NESARC-III), a national survey (N = 36,309) conducted in the USA between 2012 and 2013 were used alongside the Executive Function Index scales. The data were analyzed by using Ordinary Least Squares regression. RESULTS: Current (N = 3,681, Female = 37.7%) and former users (N = 7,448, Female = 45.4%) reported poorer cognition than never users (N = 24,956, Female = 56.6%). Self-reported cognition of former users was in-between that of current and never users. Several cannabis use characteristics were associated with self-reported cognition in current and former users. CONCLUSION: While prospective studies are required to confirm, findings suggest cannabis use is linked to worse cognition. There may be some limited recovery of cognition in former users and some cannabis use characteristics predict impairment. These findings add to our understanding of the cognitive impact of cannabis use. As worse cognitive function may impact relapse, findings have implications for personalization of cannabis use disorder treatment.

RESUMO

OBJECTIVES: This study aimed to compare the physical and mechanical properties of four denture base materials: Polyan IC (PA), milled polymethylmethacrylate (PMMA), three-dimensional (3D)-printed resin (3DP), and SR Ivocap (SR). METHODS: Ninety-six samples were prepared and divided into four groups as follows. Group A consisted of 3DP (Asiga DentaBASE, Asiga) fabricated using a manufacturer-recommended 3D printer (Asiga Pro 4k, Asiga). Group B comprised milled PMMA (MP) (Ivotion Base, Ivoclar Vivadent). Group C included PA (BredentSenden), meanwhile, group D involved SR (Ivoclar VivadentSchaan). Cuboid samples (65 mm x 10 mm x 2.5 mm) were used for biaxial flexure strength testing in a universal testing machine (UTM). Cylindrical samples of 20 mm x 40 mm were used for compressive strength testing in a UTM. Additionally, cuboid samples (65 mm x 10 mm x 2.5 mm) were used for Vickers surface hardness testing in a microhardness tester. disk samples (10 mm x 2.5 mm) were employed for color stability testing both in a coffee solution and Coca-Cola, using a digital spectrophotometer. Statistical analyses were performed using one-way analysis of variance and Tukey's post hoc analysis (α=0.05). RESULTS: MP demonstrated superior compressive strength (p = 0.002) and color stability compared to that exhibited by 3DP (p < 0.001) while displaying similar flexure strength (p = 0.336) and hardness (p = 0.708). MP and PA displayed similar compressive strength (p = 0.081), flexure strength (p = 0.159), and color stability in coke (p = 0.071). However, MP had reduced hardness (p < 0.001) and color stability in coffee (p < 0.001). Moreover, MP demonstrated a higher compressive strength (p < 0.001) than that displayed by SR. However, the flexure strength, hardness, and color stability were similar (p > 0.05). Furthermore, 3DP exhibited comparable compressive strength (p = 0.334) to that of PA but demonstrated significantly lower flexure strength (p = 0.005), hardness (p < 0.001), and color stability (p < 0.001) compared to PA. In comparison to SR, PA had a higher compressive strength (p < 0.001), hardness (p = 0.001), and color stability in coffee (p < 0.001), although they demonstrated similar (p > 0.05) flexure strength and color stability in coke. CONCLUSIONS: The MP and PA demonstrated superior compressive strength than that exhibited by the other materials tested. The tested materials had similar flexure strengths, except for PA which demonstrated superiority over the 3DP. Among all tested materials, PA exhibited the highest hardness, while the 3DP was the least color-stable. CLINICAL SIGNIFICANCE: Considering the mechanical properties and color stability, Polyan and milled polymethylmethacrylate are preferred for complete denture fabrication. However, the limited repairability and complex handling of Polyan should be considered.

RESUMO

INTRODUCTION: Over the years, implant therapy has been a commonly used treatment option for individuals who are partially or totally edentulous, with a long-term success rate of over 90%. With significant advancements in biomaterials and technology, implant dentistry can now conduct prosthetic rehabilitations in the majority of patients catering to all types of needs. However, in order to meet the demands of a patient base that is always growing, new trends in implantology are emerging in recent years that are focused on minimally invasive surgery and financial sustainability. In certain clinical scenarios, connecting teeth and implants to support fixed partial prosthesis (FPPs) may be a predictable and workable course of treatment. MATERIALS AND METHODS: 22 patients were selected for this study who had tooth and implant supported prosthesis placed as a final restoration. Out of these 22 patients; 12 were male and 10 were female patients. Implants were placed following proper protocol and if grafting procedures were required they were carried out. A second stage surgical procedure was carried out and delayed loading protocols were followed. The statistical analysis was done using the IBM SPSS 24.0, Chicago, USA. The survival of the implants and teeth were measured by the Kaplan Meier survival scale. Bone loss was assessed at baseline(upon loading), 12 months and 24 months. RESULTS: The implant survival rate was measured at 6 months, 12 months, 18 months and 24 months. At 24 months, one implant showed failure, so the survival rate of the implants were 95.4%. Bone loss of 1 mm was seen around one implant at 12 months. Bone loss of 1 and 2 mm was present around two implants and one implant respectively at 24 months. CONCLUSION: From the results of this study, we can conclude that tooth implant supported prosthesis show very good survival when used in rehabilitation cases.

RESUMO

Tooth loss is an undesirable condition that leads to functional, esthetic and social damage, having an impact on an individual's quality of life. Dental implants are man-made tooth root replacements that are increasingly used to replace a missing tooth. It is important to gather demographic data in order to take precautions before the possible failures. Hence the objective of this study was to retrospectively determine the association between age, gender, and site of implant placement in patients reporting to a private dental institution. This study was carried out from the data obtained from the case records of 1281 patients who had undergone implant therapy. Chi-square test was applied to see associations of gender, age and implant site. The results show that a maximum number of 348 implants (27.7%) were placed in patients aged between 41-50 years. The patient pool consisted of 705 (55%) females and 576 (45%) males. A maximum of 228 implants (17.80%) were placed in region 46 and 224 implants (17.49%) in region 36. Only 2 implants (0.2%) were placed in region 41. There was a positive association between age, gender and site of implant. In those aged 20-30 years, 20.53% of implants were placed, 26.23% in 31-40 years, 27.1% in 41-50 years, 17.95% in 51-60 years and 8.11% in 61-70 years of age. In male, a maximum of 124 implants (54.4%) were placed in region 46 and only 1 implant (50%) in region 41. In females, region 36 had a maximum of 110 implants (49.1%), and the least number of implants were placed in regions 31 and 41. In this study, it can be concluded that general factors such as age and gender had a significant effect on the site of implant placement.

RESUMO

INTRODUCTION: The prevalence of adults with partially dental arches is expected to be more than imagined and patients requiring replacement of missing teeth are slowly increasing in number too. Removable partial dentures are known to provide for substantial replacement for the missing teeth with also added advantages when compared to fixed or implant prosthesis, mainly in elderly patients. Denture base material performance and durability are greatly influenced by wettability and water contact angle. In the case of dentures; adequate moisture distribution is necessary to ensure excellent wettability which has an influence on comfort and oral health. The purpose of conducting this study was to find out whether the advancements made using PEEK (Polyether ether ketone) would prove to be more beneficial than the current upgrades in the current material spectrum. MATERIALS AND METHODS: This study was performed under in vitro conditions. All the fabrication and processing was done only by one operator. The materials used were divided into three groups each comprising 20 samples. Group A was modified polymethylmethacrylate (Bredent Polyan), Group B was polyoxymethylene acetal resin (Biodentaplast) and Group C was PEEK. An Ossila Goniometer was used to measure the contact angle. The three types of liquids used for the testing included distilled water, natural saliva and mouth wetting solution (Wet Mouth Liquid, ICPA India). Human saliva was collected from an individual with no medical conditions and normal salivary secretion. RESULTS: The data was analyzed using One-way ANOVA test and a pairwise comparison using the Post Hoc Tukey's Honest Significant Difference. Table 1 consists of the mean water contact angles of the denture base materials and mean contact angles of various denture base materials. In saliva, mouth wetting solution and distilled water, the highest mean and least mean contact angle was seen in Polyan and Biodentaplast respectively. A signicant difference was seen between PEEK and Polyan and Biodentaplast and Polyan on further comparison. CONCLUSION: From the resources and the materials at our disposal, it could be concluded that Polyan, Biodentaplast and PEEK and could be used as viable options in cast partial denture framework.

RESUMO

BACKGROUND: In dentistry, there is a growing preference for computer-aided design and computer-aided manufacturing (CAD/CAM) systems over traditional laboratory procedures. However, there is not much literature comparing various CAD/CAM materials. Thus, this study aimed to assess and compare the color stability and hardness of gingival and tooth colored milled and 3D-printed acrylic resins. MATERIALS AND METHODS: Four types of CAD/CAM materials were prepared: 3D-printed pink shade (PP), milled polymenthymethacrylate (PMMA) pink shade (MP), 3D-printed tooth shade (PT) and milled PMMA tooth shade (MT) (n = 6). For hardness, disc shaped samples of 15 mm × 2 mm and for color stability, bar shaped samples of 65mmx10mmx2.5 mm were prepared and polished. Vickers hardness test was performed in a microhardness tester. Color stability test was done by immersing in coffee solution and coca cola for 7 days. Day 0 and day 7 measurements were recorded using a digital spectrophotometer and the change in color was calculated. For statistical analysis, one-way ANOVA and Tukey's post hoc tests were done. RESULTS: For color stability, milled PMMA was superior to 3D-printed resin samples. Milled pink and tooth shade samples had similar color stability, whereas 3D-printed tooth shade samples were more color stable as compared to pink shade 3D-printed samples. For hardness, milled tooth shade PMMA was the most superior one, followed by 3D-printed tooth shade, whereas pink shade milled PMMA and 3D-printed resin samples had similar hardness values and were inferior to the tooth shade CAD/CAM materials. CONCLUSION: Color stability of milled PMMA is superior to that of 3D-printed resins. Hardness of tooth shade milled and 3D-printed resins is more than that of pink shade milled and 3D-printed resins.

RESUMO

Cancer patients face a significant clinical and socio-economic burden due to increased incidence, mortality, and poor survival. Factors like late diagnosis, recurrence, drug resistance, severe side effects, and poor bioavailability limit the scope of current therapies. There is a need for novel, cost-effective, and safe diagnostic methods, therapeutics to overcome recurrence and drug resistance, and drug delivery vehicles with enhanced bioavailability and less off-site toxicity. Advanced nanomaterial-based research is aiding cancer biologists by providing solutions for issues like hypoxia, tumor microenvironment, low stability, poor penetration, target non-specificity, and rapid drug clearance. Currently, nanozymes and carbon-dots are attractive due to their low cost, high catalytic activity, biocompatibility, and lower toxicity. Nanozymes and carbon-dots are increasingly used in imaging, biosensing, diagnosis, and targeted cancer therapy. Integrating these materials with advanced diagnostic tools like CT scans and MRIs can aid in clinical decision-making and enhance the effectiveness of chemotherapy, photothermal, photodynamic, and sonodynamic therapies, with minimal invasion and reduced collateral effects.

RESUMO

BACKROUND: Real-world, long-term survival outcomes of neoadjuvant, docetaxel-based therapy for esophageal and junctional adenocarcinoma are lacking. This study describes the long-term survival outcomes of patients with esophageal and junctional adenocarcinoma treated with neoadjuvant docetaxel-based chemotherapy and en bloc transthoracic esophagectomy. METHODS: A retrospective cohort analysis of a prospectively maintained database from a regional upper gastrointestinal cancer network in Quebec, Canada, was performed. From January 2007 to December 2021, all patients with locally advanced (cT3 and/or N1) esophageal/Siewert I/II adenocarcinoma treated with neoadjuvant DCFx3 (Docetaxel/Cisplatin/5FU) or FLOTx4 (5FU/Leucovorin/Oxaliplatin/Docetaxel) and transthoracic en bloc esophagectomy were identified. Postoperative, pathological, and survival outcomes were compared. RESULTS: Overall, 236 of 420 patients met the inclusion criteria. Tumor location was esophageal/Siewert I/Siewert II (118/33/85), most were cT3-4 (93.6%) and cN+ (61.0%). DCF and FLOT were used in 127 of 236 (53.8%) and 109 of 236 (46.2%). All neoadjuvant cycles were completed in 87.3% with no difference between the regimens. Operative procedures included Ivor Lewis (81.8%), left thoraco-abdominal esophagectomy (10.6%) and McKeown (7.6%) with an R0 resection in 95.3% and pathological complete response in 9.7% (DCF 12.6%/FLOT 6.4%, p = 0.111). The median lymph node yield was 32 (range 4-79), and 60.6% were ypN+. Median follow-up was longer for the DCF group (74.8 months 95% confidence interval [CI] 4-173 vs. 37.8 months 95% CI 2-119, p <0.001. Overall survival was similar between the groups (FLOT 97.3 months, 78.6-115.8 vs. DCF 92.9, 9.2-106.5, p = 0.420). CONCLUSIONS: Neoadjuvant DCF and FLOT followed by transthoracic en bloc resection are both highly effective regimens for locally advanced esophageal adenocarcinoma with equivalent survival outcomes despite high disease load.

RESUMO

BACKGROUND: Synonymous mutations, which change the DNA sequence but not the encoded protein sequence, can affect protein structure and function, mRNA maturation, and mRNA half-lives. The possibility that synonymous mutations might be enriched in cancer has been explored in several recent studies. However, none of these studies control for all three types of mutational heterogeneity (patient, histology, and gene) that are known to affect the accurate identification of non-synonymous cancer-associated genes. Our goal is to adopt the current standard for non-synonymous mutations in an investigation of synonymous mutations. RESULTS: Here, we create an algorithm, MutSigCVsyn, an adaptation of MutSigCV, to identify cancer-associated genes that are enriched for synonymous mutations based on a non-coding background model that takes into account the mutational heterogeneity across these levels. Using MutSigCVsyn, we first analyzed 2572 cancer whole-genome samples from the Pan-cancer Analysis of Whole Genomes (PCAWG) to identify non-synonymous cancer drivers as a quality control. Indicative of the algorithm accuracy we find that 58.6% of these candidate genes were also found in Cancer Census Gene (CGC) list, and 66.2% were found within the PCAWG cancer driver list. We then applied it to identify 30 putative cancer-associated genes that are enriched for synonymous mutations within the same samples. One of the promising gene candidates is the B cell lymphoma 2 (BCL-2) gene. BCL-2 regulates apoptosis by antagonizing the action of proapoptotic BCL-2 family member proteins. The synonymous mutations in BCL2 are enriched in its anti-apoptotic domain and likely play a role in cancer cell proliferation. CONCLUSION: Our study introduces MutSigCVsyn, an algorithm that accounts for mutational heterogeneity at patient, histology, and gene levels, to identify cancer-associated genes that are enriched for synonymous mutations using whole genome sequencing data. We identified 30 putative candidate genes that will benefit from future experimental studies on the role of synonymous mutations in cancer biology.

RESUMO

Background One of the frequent aesthetic issues patients confront is the loss of colour and lifeless appearance of the dentures of the base materials of their dentures after regular use. This leads to a lack of motivation to use the denture regularly. Due to the drawbacks of conventional PMMA, polyether ether ketone (PEEK) and newer polymethyl methacrylate (PMMA)-based materials have now started being used in cast partial denture frameworks due to their superior physical and biological properties. The lack of long-lasting colour is one of the main reasons for the repeat of dental prostheses. Hence, the need for the study is to help clinicians decide which would be the most suitable denture base material to be used based on colour stability. Aim To assess and compare the colour stability of PEEK, polyan, and biodentaplast denture base materials (DBMs) upon staining with distilled water, tea, coffee, and turmeric solutions after one day, seven days, and 30 days. Methods A total of 20 cuboidal specimens were constructed and immersed in distilled water, tea, coffee, and turmeric (five specimens of each material in each solution, a total of 60 specimens): Group 1: PEEK, Group 2: polyan, Group 3: biodentaplast. All specimens were subjected to colour measurements before exposure to beverage solutions, after 24 hours, on the seventh day and 30th day with a colour reflectance spectrophotometer with computer software. A one-way ANOVA test followed by post hoc Tukey's honestly significant difference (HSD) was performed for comparison of colour stability between the DBMs, revealing a significant difference between PEEK and polyan and PEEK and biodentaplast. Polyan showed the highest delta E values, followed by biodentaplast and PEEK. A two-way ANOVA test, followed by Tukey's HSD post hoc, was done to compare the staining ability of various staining solutions. Turmeric had the highest delta E values, followed by coffee, tea, and distilled water. Data were assessed using Statistical Product and Service Solutions (SPSS, version 23) (IBM SPSS Statistics for Windows, Armonk, NY) software. Results The highest mean delta E value at T1 was seen in biodentaplast immersed in turmeric (12.3900+/-0.442), and the least value at T1 was obtained for PEEK immersed in distilled water (0.4460+/-0.036). The highest mean delta E value at T2 was seen in polyan immersed in turmeric (13.0160+/-0.28962), and the least value at T2 was obtained for PEEK immersed in distilled water (0.5860+/-0.051). At T3, the highest mean delta E value was seen in polyan immersed in turmeric (16.8600+/-0.49845), and the least value at T3 was obtained for PEEK immersed in distilled water (0.700+/-0.037). Conclusion PEEK had the highest colour stability when compared with polyan and biodentaplast.

RESUMO

The outcomes of different treatment modalities for patients aged 80 and above with locally advanced and resectable esophageal carcinoma are not well described. The aim of this study was to explore survival and perioperative outcomes among this specific group of patients. A retrospective, cohort analysis was performed on a prospectively maintained esophageal cancer database from the McGill regional upper gastroinestinal cancer network. Between 2010 and 2020, all patients ≥80 years with cT2-4a, Nany, M0 esophageal carcinoma were identified and stratified according to the treatment modality: Neoadjuvant chemotherapy (nCT) or chemoradiotherapy (nCRT); definitive CRT (dCRT); upfront surgery; palliative CT/RT; or best supportive care (BSC). Of the 162 patients identified, 79 were included in this study. The median age was 83 years (80-97), most were cT3 (73%), cN- (56%), and had adenocarcinoma (62%). Treatment included: nCT/nCRT (16/79, 20%); surgery alone (19/79, 24%); dCRT (12/29, 15%); palliative RT/CT (27/79, 34%); and BSC (5/79, 6%). Neoadjuvant treatment was completed in 10/16 (63%). Of the 35/79 who underwent surgery, major complications occurred in 13/35 (37%) and 90-day mortality in 3/35 (9%). Overall survival (OS) for the cohort at 1- and 3-years was 58% and 19%. Among patients treated with nCT/nCRT, this was 94% and 46% respectively. Curative intent treatment (nCT/nCRT/upfront surgery/dCRT) had significantly increased 1- and 3- year OS compared with non-curative treatment (76%/31% vs. 34%/3.3%). Multimodal standard of care treatment is feasible and safe in select octo/nonagenarians, and may be associated with improved OS. Age alone should not bias against treatment with curative intent.

RESUMO

Neurodegenerative disorders encompass a wide range of pathological conditions caused by progressive damage to the neuronal cells and nervous-system connections, which primarily target neuronal dysfunction and result in problems with mobility, cognition, coordination, sensation, and strength. Molecular insights have revealed that stress-related biochemical alterations such as abnormal protein aggregation, extensive generation of reactive oxygen and nitrogen species, mitochondrial dysfunction, and neuroinflammation may lead to damage to neuronal cells. Currently, no neurodegenerative disease is curable, and the available standard therapies can only provide symptomatic treatment and delay the progression of the disease. Interestingly, plant-derived bioactive compounds have drawn considerable attention due to their well-established medicinal properties, including anti-apoptotic, antioxidant, anti-inflammatory, anticancer, and antimicrobial properties, as well as neuroprotective, hepatoprotective, cardioprotective, and other health benefits. Plant-derived bioactive compounds have received far more attention in recent decades than synthetic bioactive compounds in the treatment of many diseases, including neurodegeneration. By selecting suitable plant-derived bioactive compounds and/or plant formulations, we can fine tune the standard therapies because the therapeutic efficacy of the drugs is greatly enhanced by combinations. A plethora of in vitro and in vivo studies have demonstrated plant-derived bioactive compounds' immense potential, as proven by their capacity to influence the expression and activity of numerous proteins implicated in oxidative stress, neuroinflammation, apoptosis, and aggregation. Thus, this review mostly focuses on the antioxidant, anti-inflammatory, anti-aggregation, anti-cholinesterase, and anti-apoptotic properties of several plant formulations and plant-derived bioactive compounds and their molecular mechanisms against neurodegenerative disorders.

RESUMO

Purpose: Nociplastic pain distinguishes individuals with pain and hypersensitivity in body regions with apparently normal tissues, without any signs of neuropathy, but with contribution of central and/or peripheral sensitization. There is a lack of literature describing nociplastic pain in the pediatric population. The objective of this study was to investigate the differences between pediatric patients with nociplastic pain compared with patients with non-nociplastic pain. Patients and Methods: This study included 414 pediatric patients followed at an interdisciplinary centre for complex pain. All patients underwent an exhaustive pain assessment consisting of face-to-face interviews, validated self-report questionnaires and quantitative sensory testing. Recently established criteria for chronic nociplastic pain, and quantitative sensory testing was used to describe and stratify our cohort. Results: One hundred and sixty-five patients (40%) were stratified as having possible nociplastic pain and two hundred and forty-nine (60%) patients, as non-nociplastic pain. Patients with nociplastic pain displayed pain hypersensitivity in the region of pain, more symptoms of panic and social phobia, and worse sleep quality than patients with non-nociplastic pain. The proportion of patients achieving a meaningful clinical outcome after completion of their treatment (medications, physiotherapy, psychology, nursing, social worker, and/or interventional procedures) was lower in patients with nociplastic pain (62%) than those without nociplastic pain (86%). Conclusion: Our results suggest that patients who meet the criteria for nociplastic pain can be identified in a population of children and adolescents being treated in a center for complex pain. Combining screening with validated questionnaires and quantitative sensory testing facilitates the phenotyping and graded severity of patients with nociplastic pain in daily clinical practice.

RESUMO

BACKGROUND: All healthy Arab individuals are obligated to abstain from eating, drinking, and sexual relations from dawn to sunset during Ramadan, which is one of the 5 pillars of Islam. Fasting effects various body systems, apart from the renal system. Fasting can also increase serum creatinine levels because of dehydration. Our aim was to examine the effects of increased fluid intake during the night on serum creatinine and urea levels. METHODS: This randomized controlled trial included 58 healthy subjects who were randomly divided into 2 groups of 29. The hydrated group drank 2 to 3 L of fluid from sunset to the dawn of the next day. Kidney function was measured before, during, and 1 month after Ramadan. RESULTS: After adjustment for sociodemographic variables, the control group exhibited higher means of serum concentrations of creatinine and urea and lower estimated glomerular filtration rate than the hydrated group. The Ramadan group exhibited highest means of serum levels of creatinine and urea and the lowest estimated glomerular filtration rate compared with the pre- and post-Ramadan periods. All results were statistically significant at P <.05. CONCLUSIONS: We found that Ramadan fasting was not associated with a permanent increase in serum creatinine or urea. For those groups with a high fluid intake, serum creatinine and urea were significantly lower than the controls suggesting a favorable effect of hydration during the nonfasting hours. This compensated with the dehydration occurring during daylight, as dehydration is responsible for increased concentrations of urea and creatinine. This study adds further evidence that Ramadan fasting does not affect the renal system of healthy subjects; however, fluids should be increased at night, during nonfasting hours.

RESUMO

Patients with non-alcoholic fatty liver disease (NAFLD) have an increased risk of developing progressive fibrosis, cirrhosis, and hepatocellular carcinoma. As of now, there are no FDA-approved treatments for NAFLD/non-alcoholic steatohepatitis (NASH) or its associated fibrosis. Although many drugs are under clinical trial, both obeticholic acid (OCA) and semaglutide are among the few that have reached phase III clinical trials, but they were never compared. We decided to conduct a systematic review of randomized controlled trials and meta-analyses. A total of 6,589 articles were found after searching PubMed, OVID Embase, OVID Medline, PubMed Central, and clinicaltrials.gov. Only full-text peer-reviewed articles published in the past six years were put through the Cochrane bias assessment tool or the Assessment of Multiple Systematic Reviews (AMSTAR) tool to screen for bias. After strict quality assessment, data from five randomized controlled trials (n=2,694) and three systematic reviews/meta-analysis (n=8,898) was extracted and included. The data extraction from these studies showed that semaglutide and OCA cause histological improvement, but NASH resolution is exclusive to semaglutide. Although high doses of OCA can cause dyslipidemia and severe pruritus, it is the only therapeutic that causes improvement in NASH-associated hepatic fibrosis. Semaglutide is the safest option among the two and leads to significant weight loss compared to OCA; thus, a better outcome on hepatic steatosis follows. The indications of each of these drugs should be based on the NAFLD activity score and NASH fibrosis stage. OCA should be used with caution among patients with hyperlipidemia and ischemic heart disease as it may make these conditions worst.

RESUMO

Moyamoya disease is defined as stenosis of the internal carotid artery or the middle, anterior or posterior cerebral arteries with considerable collateral development. This collateral vessel has a particular appearance in angiographic examinations. Moyamoya syndrome is a term used to describe when moyamoya disease occurs in conjunction with other systemic disorders. One of the associations is Down syndrome. Moyamoya syndrome is very common in patients with Down syndrome, and the cause for this is unknown. The majority of patients present in their first decade, with the clinical presentation varying with age. The cause of moyamoya syndrome in people with trisomy 21 is unknown. This research aimed to learn more about the genesis and pathology of moyamoya syndrome in people with Down syndrome. The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were used to conduct this systematic review. Several publications connected to this topic were searched through a comprehensive database search. They were narrowed down to a final number of ten articles after applying inclusion and exclusion criteria and analyzing the quality of each work. Several possibilities were presented in these final papers to explain the link between moyamoya syndrome and trisomy 21. Trisomy 21 patients have a genetic predisposition to vascular problems. The RNF213 gene may interact with the genes on chromosome 21 that influence vascular physiology and elasticity in patients with Down syndrome, resulting in the whole picture of moyamoya syndrome.

RESUMO

Introduction: With the increasing number of cannabis users and more jurisdictions allowing medical cannabis, more evidence-based knowledge about the prevalence of cannabis use disorder (CUD) among medical users is greatly needed. Objectives: To examine and compare the prevalence and severity of CUD and the prevalence of different CUD criteria among two groups: those who combine recreational and medical use vs. those who exclusively use cannabis recreationally. To examine the association between CUD and sociodemographic characteristics, medical conditions, and psychiatric comorbidities between these two groups. Methods: The National Epidemiological Survey on Alcohol and Related Conditions III data were used, a US nationally representative in-person interview of 36,309 adults aged ≥18 years collected in 2012-2013. The statistical examination included proportion comparison hypothesis testing and linear regressions, all using complex survey design analysis procedures. Results: Recreational users who used cannabis also for medical purposes had a higher prevalence of CUD in general, as well as mild and moderate CUD than users who used cannabis only for recreational purposes. CUD is more prevalent in recreational, medical users with the following characteristics: young, male, non-white, living in the Midwest, using a greater amount of cannabis, having a concurrent mental disorder, and had CUD before the past year. Conclusion: Recreational, medical cannabis users have a higher likelihood of having CUD. Although the results should be taken with caution, given the lack of established validity of CUD among medical users, health care professionals who prescribe or recommend the use of cannabis for medical purposes should take this into consideration while evaluating the risks/benefits ratio of cannabis. They need to assess patients' recreational cannabis use, screen for CUD, and educate users about the possible complications caused by cannabis use.
