Internet addiction, sleeping habits and psychological distress in Brazilian adolescents and young adults.

BACKGROUND: The internet is widespread in modern society and has raised concerns about excessive usage and its consequences for different aging groups. OBJECTIVE: This study explores the relationships between internet addiction, sleep patterns, and psychological distress in adolescents and young adults. MATERIALS AND METHODS: In order to assess this phenomenon, an exploratory cross-sectional study was conducted in southern Brazil from October to December 2023. A questionnaire, administered via Google Forms, collected data from 618 participants aged 15-36. The participants consisted of a non-probabilistic community sample selected based on convenience criteria. Instruments included a sociodemographic questionnaire, the Internet Addiction Test, Depression, Anxiety, and Stress Scale, and Social Media Engagement Questionnaire. RESULTS: It was categorized 48.1% as having moderate internet addiction, and classified 0.8% as having severe internet addiction. Correlation analysis revealed positive associations between internet addiction and depression, anxiety, and stress. Logistic regression identified internet addiction and overall psychological distress as predictors of sleep difficulties, along with unemployment status. The findings highlight the detrimental impact of excessive internet use on sleep quality and mental health. The bidirectional relationship between internet addiction and psychological distress underscores the complex interplay between these variables. CONCLUSIONS: This study underscores the urgent need for interventions targeting internet addiction and its associated consequences in adolescents and young adults. Addressing internet addiction levels and promoting healthy internet usage habits are crucial steps in mitigating the adverse effects on mental health and sleep quality. There is a need for targeted interventions, protocols, and preventive measures to mitigate the adverse effects of excessive internet use on mental health and sleep quality. Public health strategies should include IA and its consequences in health programs with multidisciplinary approaches and protocols for treatments for behavioral addictions. The study emphasizes the multifaceted nature of internet addiction and its implications for mental health and sleep patterns.

Novel matrix formulation for resin composite: Chemical and biomechanical characterization - Part 1.

OBJECTIVE: This study aimed to investigate the effects of adding cholesteryl methacrylate (CM) monomer to experimental composite resins and evaluate its impact on polymerization shrinkage force (PSF), Knoop microhardness (KHN), sorption and solubility (SS), vulnerability to spontaneous oxidation (VOE), porosity (BES), viscosity (V), and cross-link density (CLD). CM was synthesized, mixed with varying proportions of Bis-GMA, 70 wt% filler particles, and 40 % TEGDMA. The groups tested were: CM0 (60 % Bis-GMA), CM6 (54 % Bis-GMA/6 % CM), CM12 (48 % Bis-GMA/12 % CM), CM18 (42 % Bis-GMA/18 % CM) and CM24 (36 % Bis-GMA/24 % CM). The PSF was evaluated using a universal testing machine. KHN was measured with a 50 g load for 30 s. SS was determined according to ISO 4049:2009. VOE was measured with a three-electrode system in an electrochemical cell. BES images were obtained using an electron microscope to assess porosity. Viscosity was measured through rheological analysis. CLD was estimated from hardness readings before and after ethanol storage. RESULTS: CM6 (0.34 N) and CM12 (0.34 N) exhibited the lowest PSF values compared to CM0 (0.91 N). For KHN, CM6 (32.03) and CM12 (31.03) had higher values than CM0 (25.83) and were similar to CM18 (29.39) and CM24 (28.64). SS showed no significant differences among the groups. VOE indicated low vulnerability across all groups. CM12 had greater porosity compared to CM0 in BES images. CM0 had the lowest viscosity among the groups. No differences in CLD were observed among CM0, CM12, CM18, and CM24 regarding softening effects. SIGNIFICANCE: Adding CM to Bis-GMA/TEGDMA composite resins can reduce polymerization shrinkage force and increase the initial Knoop microhardness without affecting the other properties studied.

Advancements in reperfusion rates and quality of care for ST-segment elevation myocardial infarction: a ten-year evaluation of Salvador's STEMI network.

Background: Continuous investment and systematic evaluation of program accomplishments are required to achieve excellence in ST-segment elevation myocardial infarction (STEMI) care, especially in resource-limited settings. Therefore, this study evaluates the impact of problem-driven interventions on reperfusion use rate in a long-term operating STEMI network from a low- to middle-income country. Methods: This is a healthcare improvement evaluation study of Salvador's public STEMI network in a quasi-experimental design, comparing data from 2009 to 2010 (pre-intervention) and 2019-2020 (post-intervention). There were evaluated all confirmed STEMI cases assisted in both periods. The interventions, implemented since 2017, included: expanding the support team, defining criteria to be a spoke, and initiating continuous education activities. The primary outcome was the rate of patients undergoing reperfusion, with secondary outcomes being time from door-to-ECG (D2E) and ECG-to-STEMI-team trigger (E2T). Results: Over ten years, the network's coverage increased by 300,000 individuals, and expanded by 1,800 km2. A total of 885 records were analyzed, 287 in the pre-intervention group (182 men [63·4%]; mean [SD] age 62·1 [12·5] years) and 598 in the post-intervention group (356 men [59·5%]; mean [SD] age 61.9 [11·8] years). It was noticed a substantial increase in reperfusion delivery rate (90 [31%] vs. 431 [73%]; P = 001) and reductions in time from D2E (159 [83-340] vs. 29 [15-63], P = 001), and E2T (31 [21-44] vs. 16 [6-40], P = 001). Conclusion: The strategies adopted by Salvador's STEMI network were associated with significant improvements in the rate of patients undergoing reperfusion and in D2E and E2T. However, the mortality rate remains high.

Predictors of Suicidal Behavior in a Sample of Incarcerated Individuals.

INTRODUCTION: Incarcerated individuals exhibit higher suicide rates compared to the general population. Investigating risk factors aids in developing effective public policies and interventions. The goal of this study was to assess and analyze factors predicting both suicidal thoughts and suicide attempts in a population of male incarcerated individuals who engage in the use of multiple psychoactive substances. METHODS: A cross-sectional observational study was conducted. A total of 174 male individuals deprived of liberty participated in the study, all of whom were serving a closed regime sentence during the data collection steps. Participants were assessed with the following instruments: the "Addiction Severity Index" (ASI-6) and the "Barratt Impulsiveness Scale" (BIS-11). RESULTS: Amongst our sample, prevalences of 36.7% in suicidal ideation and of 16.0% in suicide attempts were found. Impulsivity (OR = 1.098, 95% CI: 1.008 - 1.197), social support (OR = 0.281, 95% CI: 0.085 - 0.925), witnessing someone being killed or beaten (OR = 5.173, 95% CI: 2.143 - 12.486), cigarette use (OR = 3.309, 95% CI: 1.063 - 10.293), and cocaine use (OR = 2.678, 95% CI: 1.040 - 6.897) were also found to be associated with suicidal ideation. No significant associations were found between drug use and suicide attempts. CONCLUSION: A high prevalence of suicidal behaviors was observed in the study's sample, with findings demonstrating that impulsivity moderately differentiates the groups 'with' and 'without' suicidal ideation. Traumatic life events and substance use were also associated with suicide ideation, while social support was established as a protective factor for it.

Eco-alternative treatments for Vibrio parahaemolyticus and V. cholerae biofilms from shrimp industry through Eucalyptus (Eucalyptus globulus) and Guava (Psidium guajava) extracts: A road for an Ecuadorian sustainable economy.

Understanding how environmental variables influence biofilm formation becomes relevant for managing Vibrio biofilm-related infections in shrimp production. Therefore, we evaluated the impact of temperature, time, and initial inoculum in the biofilm development of these two Vibrio species using a multifactorial experimental design. Planktonic growth inhibition and inhibition/eradication of Vibrio biofilms, more exactly V. parahaemolyticus (VP87 and VP275) and V. cholerae (VC112) isolated from shrimp farms were evaluated by Eucalyptus and Guava aqueous leaf extracts and compared to tetracycline and ceftriaxone. Preliminary results showed that the best growth conditions of biofilm development for V. parahaemolyticus were 24 h and 24°C (p <0.001), while V. cholerae biofilms were 72 h and 30°C (p <0.001). Multivariate linear regression ANOVA was applied using colony-forming unit (CFU) counting assays as a reference, and R-squared values were applied as goodness-of-fit measurements for biofilm analysis. Then, both plant extracts were analyzed with HPLC using double online detection by diode array detector (DAD) and mass spectrometry (MS) for the evaluation of their chemical composition, where the main identified compounds for Eucalyptus extract were cypellogin A, cypellogin B, and cypellocarpin C, while guavinoside A, B, and C compounds were the main compounds for Guava extract. For planktonic growth inhibition, Eucalyptus extract showed its maximum effect at 200 µg/mL with an inhibition of 75% (p < 0.0001) against all Vibrio strains, while Guava extract exhibited its maximum inhibition at 1600 µg/mL with an inhibition of 70% (p < 0.0001). Both biofilm inhibition and eradication assays were performed by the two conditions (24 h at 24°C and 72 h at 30°C) on Vibrio strains according to desirability analysis. Regarding 24 h at 24°C, differences were observed in the CFU counting between antibiotics and plant extracts, where both plant extracts demonstrated a higher reduction of viable cells when compared with both antibiotics at 8x, 16x, and 32x MIC values (Eucalyptus extract: 1600, 3200, and 6400 µg/mL; while Guava extract: 12800, 25600, and 52000 µg/mL). Concerning 72 h at 30°C, results showed a less notorious biomass inhibition by Guava leaf extract and tetracycline. However, Eucalyptus extract significantly reduced the total number of viable cells within Vibrio biofilms from 2x to 32x MIC values (400-6400 µg/mL) when compared to the same MIC values of ceftriaxone (5-80 µg/mL), which was not able to reduce viable cells. Eucalyptus extract demonstrated similar results at both growth conditions, showing an average inhibition of approximately 80% at 400 µg/mL concentration for all Vibrio isolates (p < 0.0001). Moreover, eradication biofilm assays demonstrated significant eradication against all Vibrio strains at both growth conditions, but biofilm eradication values were substantially lower. Both extract plants demonstrated a higher reduction of viable cells when compared with both antibiotics at 8x, 16x, and 32x MIC values at both growth sets, where Eucalyptus extract at 800 µg/mL reduced 70% of biomass and 90% of viable cells for all Vibrio strains (p < 0.0001). Overall results suggested a viable alternative against vibriosis in the shrimp industry in Ecuador.

Characterization of experimental resin composites with cholesteryl methacrylate organic matrix - Part 2.

OBJECTIVE: The aim of this study was to evaluate the degree of conversion (%), flexural strength (MPa), elastic modulus (GPa), compressive strength (MPa), Knoop microhardness (KHN), post-gel shrinkage (%) and prediction of ideal concentration of cholesteryl methacrylate (CM) in experimental resins. METHODS: Four formulations were manipulated (F): F1, control group, (0 % CM); F2 (15 % CM); F3 (19.8 % CM) and F4 (30 % CM). Bis-GMA and CM percentages were determined using Statistica™ software. For the degree of conversion test, Raman spectroscopy was used. To testing flexural strength, elastic modulus and compressive strength, a universal testing machine was used. For the Knoop microhardness test five indentations were made in each sample. Post-gel shrinkage was determined using the strain gauge method. Statistica™ software processed all data obtained in this study. Results were submitted to one-way ANOVA and Tukey's post hoc tests (α = 0.05). RESULTS: Better performance was observed for F2 (15 % CM) and F3 (19,8 % CM) for degree of conversion, elastic modulus and post-gel shrinkage. For Knoop microhardness F2 (15 % CM), F3 (19,8 % CM) and F4 (30 % CM) showed higher values than F1 (0 % CM). For flexural strength F1 (0 % CM) and F3 (19,8 %) were similar and F4 showed the lowest values and for compressive strength F1 (0 % CM) showed the highest values. For mixture designs analysis data, concentrations ≤ 25 % of CM would provide better results. SIGNIFICANCE: Addition of CM at concentrations lower than 30 % contributed to a significant increase in the degree of conversion, microhardness values, elastic modulus and reduction of post-gel shrinkage.

The Effect of Immune Checkpoint Inhibitor Therapy on Pre-Existing Gastroparesis and New Onset of Symptoms of Delayed Gastric Emptying.

Immune checkpoint inhibitors (ICIs) can cause myenteric plexopathy, which could result in delayed gastric emptying (GE) and possibly gastroparesis. We assessed the clinical outcomes of patients who had pre-existing gastroparesis or who developed symptoms of delayed GE following ICI therapy. We retrospectively identified adults with ICD-9 and ICD-10 codes for gastroparesis who received ICI therapy between 1 January 2020 and 31 December 2022 at a tertiary cancer center. Of 76 eligible patients, 37 had pre-existing gastroparesis; 39 (0.2% of the more than 18,000 screened) developed symptoms of delayed GE after ICI therapy, of which 27 (69%) patients had an alternative etiology for delayed GE. Four patients (11%) with pre-existing gastroparesis had a flare-up after ICI, and the median time to flare-up was 10.2 months (IQR, 0.7-28.6 months); for patients with new onset of suspected delayed GE after ICI, the median time to symptom onset was 12.8 months (IQR, 4.4-35.5 months). The clinical symptom duration of patients without an alternative etiology (74.5 days (IQR, 21.5-690 days)) and those with an alternative etiology (290 days (IQR, 147-387 days)) did not differ significantly (p = 1.00). Delayed GE after ICI therapy is a rare presentation but has a late onset and a prolonged symptom duration.

A chemical analysis of the Pelargonium species: P. odoratissimum, P. graveolens, and P. zonale identifies secondary metabolites with activity against gram-positive bacteria with multidrug-resistance.

The Pelargonium genus encompasses around 280 species, most of which are used for medicinal purposes. While P. graveolens, P. odoratissimum, and P. zonale are known to exhibit antimicrobial activity, there is an evident absence of studies evaluating all three species to understand their chemical differences and biological effects. Through the analysis of the hydroalcoholic extracts of P. graveolens, P. odoratissimum, and P. zonale, using HPLC-DAD-MS/MS, quercetin and kaempferol derivatives were identified in these three species. Conversely, gallotannins and anthocyanins were uniquely detected in P. zonale. P. graveolens stood out due to the various types of myricetin derivatives that were not detected in P. odoratissimum and P. zonale extracts. Evaluation of their biological activities revealed that P. zonale displayed superior antibacterial and antibiofilm activities in comparison to the other two species. The antibacterial efficacy of P. zonale was observed towards the clinically relevant strains of Staphylococcus aureus ATCC 25923, Methicillin-resistant Staphylococcus aureus (MRSA) 333, Enterococcus faecalis ATCC 29212, and the Vancomycin-resistant E. faecalis INSPI 032. Fractionation analysis of P. zonale suggested that the antibacterial activity attributed to this plant is due to the presence of quercetin derivatives and kaempferol and its derivatives, alongside their synergistic interaction with gallotannins and anthocyanins. Lastly, the three Pelargonium species exhibited notable antioxidant activity, which may be attributed to their high content of total phenolic compounds.

Gastrointestinal toxicities of proteasome inhibitor therapy.

PURPOSE: Proteasome inhibitors (PIs), which cause cell death via tumor suppressor and pro-apoptotic proteins, are integral to treatment of many hematologic malignancies but are limited by their gastrointestinal adverse effects. Evidence regarding these PI-related adverse effects is scant. In this study, we evaluated gastrointestinal adverse events caused by PIs and compared gastrointestinal toxicities between bortezomib, carfilzomib, and ixazomib. METHODS: We conducted a retrospective study of cancer patients treated with PIs at a tertiary care cancer center to investigate the clinical characteristics of PI-related gastrointestinal adverse events. RESULTS: Our sample comprised 973 patients with PI exposure and stool studies ordered between January 2017 and December 2022. Of these, 193 patients (20%) had PI-related gastrointestinal toxicity based on clinical symptoms and stool study results. The most common symptom was diarrhea, present in 169 (88% of those with gastrointestinal toxicity). Twenty-two (11%) required hospitalization, and 71 (37%) developed recurrence of symptoms. Compared to bortezomib or carfilzomib, ixazomib had a longer interval from PI initiation to the onset of gastrointestinal symptoms (313 days vs 58 days vs 89 days, p = 0.002) and a significantly lower percentage of diarrhea-predominant presentation of gastrointestinal toxicity (71% vs 96% vs 91%, p = 0.048). CONCLUSION: While PI-related gastrointestinal toxicities have various presentations and courses based on different regimens, the vast majority of patients presented with milder disease behavior. Despite a considerably high rate of hospitalization and recurrence after treatment necessitating optimization of clinical management, our cohort demonstrates favorable outcomes without long-term consequences.

The Impact of Intraoperative Glucagon on the Diagnostic Accuracy of Intraoperative Cholangiogram for the Diagnosis of Choledocholithiasis: Experience from a Large Tertiary Care Center.

A proportion of patients who undergo intraoperative cholangiogram (IOC) do not have bile duct stones at the time of endoscopic retrograde cholangiopancreatography (ERCP), either due to the spontaneous passage of stones or a false-positive IOC. Glucagon has been utilized as an inexpensive tool to allow the passage of micro-choledocholithiasis to the duodenum and resolve filling defects caused by stones or air bubbles. The purpose of our study is to understand the change in diagnostic accuracy of IOC to detect choledocholithiasis with intraoperative glucagon. We conducted a retrospective study at a tertiary care center on adult patients who underwent laparoscopic cholecystectomy with IOC. The diagnostic accuracy of IOC was assessed before and after the administration of intravenous glucagon. Of 1455 patients, 374 (25.7%) received intraoperative glucagon, and 103 of these 374 patients (27.5%) showed resolution of the filling defect with the passage of contrast to the duodenum. Pre- and post-glucagon administration comparison showed enhancement in specificity from 78% to 83%, an increase in positive predictive value from 67.3% to 72.4%, and an improvement in the diagnostic accuracy of IOC from 81.5% to 84.3%. Our findings suggest that intraoperative glucagon administration carries the potential to reduce the rate of false-positive IOCs, thereby reducing the performance of unnecessary ERCPs.

Outcomes of Budesonide as a Treatment Option for Immune Checkpoint Inhibitor-Related Colitis in Patients with Cancer.

BACKGROUND: Current treatment guidelines for moderate to severe colitis (IMC) secondary to immune checkpoint inhibitors (ICI) recommend systemic corticosteroids as the primary therapy in conjunction with biologics, namely infliximab and/or vedolizumab. We aimed to explore the efficacy and safety of oral budesonide in the treatment of IMC. METHODS: We performed a retrospective analysis at MD Anderson Cancer Center of adult cancer patients with a confirmed (based on clinical, radiographic and laboratory assessment) diagnosis of IMC between 1 January 2015 and 31 November 2022, treated with budesonide. Data collection included demographics, oncologic history, IMC-related information and outcomes up to 6 months after the last dose of ICI. RESULTS: Our sample (n = 69) comprised primarily of Caucasian (76.8%) females (55.1%). The majority of patients received combination therapy with anti-PD-1/L1 and anti-CTLA-4 (49.3%), and the most common malignancy treated was melanoma (37.6%). The median grade of diarrhea was 3 and of colitis was 2. Of the 50 patients who underwent endoscopic evaluation, a majority had non-ulcerative inflammation (64%) and active colitis on histology (78%). Budesonide was used as primary treatment at onset of IMC in 56.5% patients, as well as a bridging therapy from systemic corticosteroids in 33.3%. Less than half of the patients (44.9%) required additional therapies such as biologics or fecal microbiota transplant. Additionally, 75.3% of patients achieved full remission of IMC and 24.6% had a recurrence of IMC. ICI was resumed in 31.9% of patients and 17.4% received other forms of cancer therapies. CONCLUSIONS: Budesonide may be an effective strategy to treat and prevent the recurrence of IMC. The remission rates observed in our analysis with budesonide alone are comparable to systemic corticosteroids. Patients that require an extended duration of steroid exposure and those with moderate to severe colitis may benefit from budesonide given its lower risk of infection and complications. Furthermore, we observe that budesonide may serve as a successful bridge from systemic corticosteroids with subsequent biologic treatment. Larger prospective studies are necessary to determine the role of budesonide as well as its safety profile.

Genetic legacies of mega-landslides: Cycles of isolation and contact across flank collapses in an oceanic island.

Catastrophic flank collapses are recognized as important drivers of insular biodiversity dynamics, through the disruption of species ranges and subsequent allopatric divergence. However, little empirical data supports this conjecture, with their evolutionary consequences remaining poorly understood. Using genome-wide data within a population genomics and phylogenomics framework, we evaluate how mega-landslides have impacted evolutionary and demographic history within a species complex of weevils (Curculionidae) within the Canary Island of Tenerife. We reveal a complex genomic landscape, within which individuals of single ancestry were sampled in areas characterized by long-term geological stability, relative to the timing of flank collapses. In contrast, individuals of admixed ancestry were almost exclusively sampled within the boundaries of flank collapses. Estimated divergence times among ancestral populations aligned with the timings of mega-landslide events. Our results provide first evidence for a cyclical dynamic of range fragmentation and secondary contact across flank collapse landscapes, with support for a model where this dynamic is mediated by Quaternary climate oscillations. The context within which we reveal climate and topography to interact cyclically through time to shape the geographic structure of genetic variation, together with related recent work, highlights the importance of topoclimatic phenomena as an agent of diversification within insular invertebrates.

Association between hospitalizations for sensitive conditions and quality of primary care.

OBJECTIVE: To analyze the association between municipal rates of ambulatory care sensitive conditions (ACSC) hospitalization and the quality of primary health care (PHC), socioeconomic, and demographic variables and those related to local characteristics of the health system from 2010 to 2019. METHOD: Ecological time series study in Brazilian municipalities analyzing the correlation of ACSC hospitalization rates with PHC quality measured by the three cycles of the Primary Care Access and Program for improving primary care access and quality (PMAQ-AB). The study included municipalities whose teams participated in 80% or more of at least two PMAQ-AB cycles. The correlation between standardized ACSC hospitalization rates and PHC quality and other variables was analyzed. Spearman's test was used between the response variable and numerical explanatory variables. Generalized equations estimation was used as a multivariate model associating ACSC hospitalization rates with the other variables over the years. RESULTS: A total of 3,500 municipalities were included in the models. The quality of PHC (PMAQ-AB score) showed an inverse association with the variation in ACSC hospitalization rates. Hospitalization rates fell by -2% per year every ten-point increase in the PMAQ-AB score, adjusted by the remaining variables. A one-unit increase in the beds per 1,000 inhabitants variable had an impact of approximately +6.4% on ACSC hospitalization rates. Regarding population size, larger municipalities had lower ACSC hospitalization rates. Increased PHC coverage and lower socioeconomic inequality were also associated with the reduction in hospitalizations. CONCLUSIONS: The reduction in ACSC hospitalization rates over time was associated with an increase in the quality of PHC. It was also associated with a reduction in the number of hospital beds and municipalities with better socioeconomic indicators.

Colon Adenoma After Diagnosis of Immune Checkpoint Inhibitor-mediated Colitis.

Purpose: While the occurrence of colitis during immune checkpoint inhibitor (ICI) treatment is recognized as a sign of robust immune activation and correlates with better oncological outcomes, the long-term impact of ICI-mediated colitis on the colonic mucosa has not been studied. We thus aim to describe the colonoscopy and histology findings in patients at a follow-up time of ≥ 6 months post initial colitis event. Methods: This retrospective analysis included adult cancer patients diagnosed with ICI colitis at a tertiary cancer center between October 2013 and June 2020. The study group included patients diagnosed with immune mediated colitis who had also undergone a follow up colonoscopy or flex sigmoidoscopy. The control group was patients exposed to ICI without immune mediated colitis. We reported patients' colitis clinical course, treatment, outcomes, and endoscopic and histologic features at diagnosis and at follow-up time of ≥ 6 months. Results: Total 39 patients met the study criteria, with 82% being male, and 35.8% having melanoma. Most patients received a combination of CTLA-4 and PD-1/L1 inhibitors (82%). On initial endoscopic evaluation, inflammation without ulceration was reported in 76.9% of patients and active inflammation on histologic examination in 79.3% of patients. Most patients (79.4%) received corticosteroids, and 56.4% received add-on selective immunosuppressive therapy. Four patients received fecal microbiota transplantation. On follow-up, new incidence of colonic polyps was reported in 51.2% of patients, including adenomas in 33.3% among the colitis patients with median follow up duration of 12 months. The incidence of adenoma polyps 12 months after the colitis event was significantly higher compared to the control group without colitis based on the time-to-event analysis (p=0.041). Conclusion: At a median follow up of 12 months after their initial colitis diagnosis, 51.2% of the patients had new incidence of colonic polyps, including a third with adenoma, at a significantly higher incidence than the control group without colitis. Studies with larger sample sizes are needed to further define the long-term impact of colitis and its treatments on colon health and to refine recommendations for surveillance of colonic adenomas and colorectal cancer.

The Safety of Immunosuppressants Used in the Treatment of Immune-Related Adverse Events due to Immune Checkpoint Inhibitors: a Systematic Review.

Purpose: Immune checkpoint inhibitor (ICI) use can lead to immune-related adverse events (irAEs) that require treatment with immunosuppressive medications in moderate to severe cases. Oncology society guidelines recommend systemic steroids and immunosuppressants such as infliximab and vedolizumab for the treatment of refractory cases. Limited information is available about the safety profile and potential adverse effects of these immunosuppressants. We have investigated the safety profile of multiple immunosuppressants which are used in the treatment of ICI-related irAEs. Methods: We performed a systematic review of studies reporting irAEs, from ICI use, and their medical management with immunosuppressants in adult cancer patients. We searched MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials.gov from inception through September 1, 2022, using the following keywords or their equivalents: ICI, immunosuppressant, and irAE. We extracted observational studies and clinical trials that matched our criteria. A random effects model was used to estimate the overall incidence of infections associated with the treatment of irAEs. Results: Among the 11 studies included in this review (1036 total patients), melanoma (548 patients, 52.9%) was the most common primary cancer, followed by lung cancer (139 patients, 13.4%) and genitourinary cancers (131 patients, 12.6%). PD-1/PD-L1 monotherapy (460 patients, 44.4%) was used most, followed by a combination of PD-1/PD-L1 and CTLA-4 therapy (350 patients, 33.8%) and CTLA-4 monotherapy (226 patients, 22%). A total of 1024 (98.8%) patients had their irAEs treated with systemic steroids with majority having colitis and hepatobiliary irAEs; 335 patients (32.3%) were also treated with infliximab (mainly for colitis). Our review found 22.3% of patients treated for irAEs developed infectious adverse events (95% CI: 15.6%-29.1%, p<0.001). Among the 3 studies reporting the types of infections (41 total patients), bacterial (80.5%), followed by fungal (36.6%), infections were most common. Conclusions: Adverse events from irAE treatment occurred in about one-third of patients that received either steroids or a combination of steroids and other immunosuppressants. Clinicians should be aware of these immunosuppressant-related adverse effects, which can negatively impact cancer treatment and patient outcomes, when treating irAEs and consider shortening treatment duration or using alternative strategies when possible to mitigate these complications, future prospective studies should further investigate the safety of immunosuppressants in treating irAEs.

Transformations in the world of healthcare work: workers and future challenges. / Transformações no mundo do trabalho em saúde: os(as) trabalhadores(as) e desafios futuros.

This article addresses the world of healthcare work, especially in the Brazilian Unified Healthcare System (SUS) in the context of the COVID-19 pandemic in Brazil. This study used data from the following surveys: "Working conditions of health professionals in the context of COVID-19 in Brazil" and "The Invisible health workers: working conditions and mental health in the context of COVID-19 in Brazil". Data analysis proves that the pandemic highlighted existing structural problems within SUS, involving the issue of healthcare workforce (HWF) management, which can be interpreted as another reflection of the socioeconomic inequalities that already exist in the country. This article highlights: the reduced provision of permanent education, the regulation of hybrid care, precariousness, a lack of protection in the work environment, as well as fragile biosecurity leading to tragic rates of illness and death of health workers. Our study concludes by showing the importance of formulating public policies in the scope of education and work management in SUS that ensure the discussion on hybrid care as a new way of acting without losing quality, together with the need to review issues related to permanent education, protection, valuation, and reduction of inequalities pointed out among the professional contingents analyzed in this article.

O artigo versa sobre o mundo do trabalho da saúde, especialmente no SUS no contexto da pandemia no Brasil. O artigo utilizou dados das pesquisas "Condições de trabalho dos profissionais de saúde no contexto da COVID-19 no Brasil" e "Os trabalhadores invisíveis da saúde: condições de trabalho e saúde mental no contexto da COVID-19 no Brasil". A análise dos dados comprova que a pandemia evidenciou problemas estruturais existentes no âmbito do Sistema Único de Saúde, envolvendo a gestão da FTS o que pode ser interpretado como mais um dos reflexos das desigualdades socioeconômicas já existentes no país. Destacam-se: a reduzida oferta de educação permanente, a regulação do cuidado híbrido, precarização, desproteção no ambiente de trabalho, frágil biossegurança levando a trágicas taxas de adoecimento e mortes de trabalhadores da saúde. Conclui mostrando a importância de formulação de políticas públicas no âmbito da gestão da educação e do trabalho no SUS que assegurem a discussão sobre cuidado híbrido como nova forma de atuar sem perder qualidade, a necessidade de se rever questões referentes a: educação permanente, proteção, valorização e redução das desigualdades apontadas entre os contingentes profissionais analisados nesse artigo.

Comorbities and mental health among healthcare workers in Brazil. The impact of the COVID-19 pandemic. / Comorbidades e saúde mental dos trabalhadores da saúde no Brasil. O impacto da pandemia da COVID-19.

This is an original article that addresses the healthcare workforce (HW) in Brazil, as well as comorbidities and mental health changes during the COVID-19 pandemic. This study was conducted by the Oswaldo Cruz Foundation and collected data through an online questionnaires from a total of 36,612 participants, health professionals (HP, with higher education level), and invisible healthcare workers (IHW, with a technical mid-level education). The overall prevalence of comorbidities in Brazil was 26.1% and 23.9%; the highest was arterial hypertension (27.4% and 31.9%), followed by obesity (18.4% and 15.1%), chronic respiratory diseases (15.7% and 12.9%), diabetes mellitus (10.3% and 10.4%), and depression/anxiety (9.1% and 11.7%), in the HW and IHW, respectively. The region with the highest frequency was the southeast, where the largest contingent of workers is located. The HW, affected with a high burden of non-communicable chronic diseases and exposed to SARS-CoV-2, proved to be vulnerable to illness and death. Mental symptoms and intense psychological suffering have been reported. These results allow us to estimate the impacts upon physical and mental health, as well as upon living and working conditions of the HW. The health and life of workers, leading role in facing health challenges of the pandemic, are a high priority in public policies.

Trata-se de um artigo original que aborda a força de trabalho (FT) em saúde no Brasil, suas comorbidades e alterações da saúde mental na pandemia da COVID-19. O estudo conduzido pela Fundação Oswaldo Cruz coletou dados por meio de questionário on-line com um total de 36.612 participantes: profissionais de saúde (PS, formação de nível superior), e trabalhadores invisíveis (TI, nível técnico). A prevalência de comorbidades no Brasil foi de 26,1% e 23,9%, a maior foi hipertensão arterial (27,4% e 31,9%), seguida da obesidade (18,4% e 15,1%), doenças crônicas respiratórias (15,7% e 12,9%), diabetes mellitus (10,3% e 10,4%), e depressão/ansiedade (9,1% e 11,7%), nos PS e TI, respectivamente. A região com maior frequência foi a sudeste onde concentra-se o maior contingente de trabalhadores. A FT acometida com alta carga de doenças crônicas não transmissíveis e exposta ao SARS-CoV-2, torna-se vulnerável para o adoecimento e morte. Sintomas mentais e intenso sofrimento psíquico foram relatados. Os resultados deste estudo nos permitem estimar o impacto na saúde física e mental, e nas condições de vida e de trabalho da FT. A saúde e a vida dos trabalhadores, protagonistas no enfrentamento dos desafios da pandemia, são prioridade nas políticas públicas.

Enfatiza as recomendações da OMS/OPAS, a necessidade de vacinação equânime, incluindo os países mais pobres e as populações mais vulneráveis. Relata os impactos da interrupção dos serviços essenciais em saúde, como para as doenças crônicas e infecciosas, e os prejuízos causados pela disseminação de informações falsas pela rede social, e lembra da necessidade de veiculação de informações corretas e seguras na saúde.

Transformações no mundo do trabalho em saúde: os(as) trabalhadores(as) e desafios futuros / Transformations in the world of healthcare work: workers and future challenges

Resumo O artigo versa sobre o mundo do trabalho da saúde, especialmente no SUS no contexto da pandemia no Brasil. O artigo utilizou dados das pesquisas "Condições de trabalho dos profissionais de saúde no contexto da COVID-19 no Brasil" e "Os trabalhadores invisíveis da saúde: condições de trabalho e saúde mental no contexto da COVID-19 no Brasil". A análise dos dados comprova que a pandemia evidenciou problemas estruturais existentes no âmbito do Sistema Único de Saúde, envolvendo a gestão da FTS o que pode ser interpretado como mais um dos reflexos das desigualdades socioeconômicas já existentes no país. Destacam-se: a reduzida oferta de educação permanente, a regulação do cuidado híbrido, precarização, desproteção no ambiente de trabalho, frágil biossegurança levando a trágicas taxas de adoecimento e mortes de trabalhadores da saúde. Conclui mostrando a importância de formulação de políticas públicas no âmbito da gestão da educação e do trabalho no SUS que assegurem a discussão sobre cuidado híbrido como nova forma de atuar sem perder qualidade, a necessidade de se rever questões referentes a: educação permanente, proteção, valorização e redução das desigualdades apontadas entre os contingentes profissionais analisados nesse artigo.

Abstract This article addresses the world of healthcare work, especially in the Brazilian Unified Healthcare System (SUS) in the context of the COVID-19 pandemic in Brazil. This study used data from the following surveys: "Working conditions of health professionals in the context of COVID-19 in Brazil" and "The Invisible health workers: working conditions and mental health in the context of COVID-19 in Brazil". Data analysis proves that the pandemic highlighted existing structural problems within SUS, involving the issue of healthcare workforce (HWF) management, which can be interpreted as another reflection of the socioeconomic inequalities that already exist in the country. This article highlights: the reduced provision of permanent education, the regulation of hybrid care, precariousness, a lack of protection in the work environment, as well as fragile biosecurity leading to tragic rates of illness and death of health workers. Our study concludes by showing the importance of formulating public policies in the scope of education and work management in SUS that ensure the discussion on hybrid care as a new way of acting without losing quality, together with the need to review issues related to permanent education, protection, valuation, and reduction of inequalities pointed out among the professional contingents analyzed in this article.
