RESUMO

Posttransplant lymphoproliferative disorder (PTLD) poses a significant concern in Epstein-Barr virus (EBV)-negative patients transplanted from EBV-positive donors (EBV R-/D+). Previous studies investigating the association between different induction agents and PTLD in these patients have yielded conflicting results. Using the Organ Procurement and Transplant Network database, we identified EBV R-/D+ patients >18 years of age who underwent kidney-alone transplants between 2016 and 2022 and compared the risk of PTLD with rabbit antithymocyte globulin (ATG), basiliximab, and alemtuzumab inductions. Among the 6620 patients included, 64.0% received ATG, 23.4% received basiliximab, and 12.6% received alemtuzumab. The overall incidence of PTLD was 2.5% over a median follow-up period of 2.9 years. Multivariable analysis demonstrated that the risk of PTLD was significantly higher with ATG and alemtuzumab compared with basiliximab (adjusted subdistribution hazard ratio [aSHR] = 1.98, 95% confidence interval [CI] 1.29-3.04, P = .002 for ATG and aSHR = 1.80, 95% CI 1.04-3.11, P = .04 for alemtuzumab). However, PTLD risk was comparable between ATG and alemtuzumab inductions (aSHR = 1.13, 95% CI 0.72-1.77, P = .61). Therefore, the risk of PTLD must be taken into consideration when selecting the most appropriate induction therapy for this patient population.

RESUMO

BACKGROUND: Glycerol-3-phosphate acyltransferase (GPAT) activity is correlated with obesity and insulin resistance in mice and humans. However, insulin resistance exists in people with normal body weight, and individuals with obesity may be metabolically healthy, implying the presence of complex pathophysiologic mechanisms underpinning insulin resistance. OBJECTIVE: We asked what conditions related to GPAT1 must be met concurrently for hepatic insulin resistance to occur. METHODS: Mouse hepatocytes were overexpressed with GPATs via adenoviral infection or exposed to high or low concentrations of glucose. Glucose production by the cells and phosphatidic acid (PA) content in the cells were assayed, GPAT activity was measured, relative messenger RNA expressions of sterol-regulatory element-binding protein 1c (SREBP1c), carbohydrate response element-binding protein (ChREBP), and GPAT1 were analyzed, and insulin signaling transduction was examined. RESULTS: Overexpressing GPAT1 in mouse hepatocytes impaired insulin's suppression of glucose production, together with an increase in both N-ethylmaleimide-resistant GPAT activity and the content of di-16:0 PA. Akt-mediated insulin signaling was inhibited in hepatocytes that overexpressed GPAT1. When the cells were exposed to high-glucose concentrations, insulin suppression of glucose production was impaired, and adding palmitic acid exacerbated this impairment. High-glucose exposure increased the expression of SREBP1c, ChREBP, and GPAT1 by ∼2-, 5-, and 5.7-fold, respectively. The addition of 200 mM palmitic acid or linoleic acid to the culture media did not change the upregulation of expression of these genes by high glucose. High-glucose exposure increased di-16:0 PA content in the cells, and adding palmitic acid further increased di-16:0 PA content. The effect was specific to palmitic acid because linoleic acid did not show these effects. CONCLUSION: These data demonstrate that high-GPAT1 activity, whether induced by glucose exposure or acquired by transfection, and abundant palmitic acid can impair insulin's ability to suppress hepatic glucose production in primary mouse hepatocytes.

RESUMO

The dewetting of thin Pt films on different surfaces is investigated as a means to provide the patterning for the top-down fabrication of GaN nanowire ensembles. The transformation from a thin film to an ensemble of nanoislands upon annealing proceeds in good agreement with the void growth model. With increasing annealing duration, the size and shape uniformity of the nanoislands improves. This improvement speeds up for higher annealing temperature. After an optimum annealing duration, the size uniformity deteriorates due to the coalescence of neighboring islands. By changing the Pt film thickness, the nanoisland diameter and density can be quantitatively controlled in a way predicted by a simple thermodynamic model. We demonstrate the uniformity of the nanoisland ensembles for an area larger than 1 cm2. GaN nanowires are fabricated by a sequence of dry and wet etching steps, and these nanowires inherit the diameters and density of the Pt nanoisland ensemble used as a mask. Our study achieves advancements in size uniformity and range of obtainable diameters compared to previous works. This simple, economical, and scalable approach to the top-down fabrication of nanowires is useful for applications requiring large and uniform nanowire ensembles with controllable dimensions.

RESUMO

While the incidence of hypercalcemia of malignancy (HCM) is on the decline, it still occurs in up to 30% of patients with cancer. Immune checkpoint inhibitor (ICI)-related hypercalcemia is becoming increasingly recognized. We describe a case of cemiplimab-induced hypercalcemia in a patient with metastatic squamous cell carcinoma of the earlobe and discuss a management algorithm for HCM. Timely diagnosis and management of HCM is critical for optimal care and the prevention of complications.

RESUMO

Mental illness definitions and classifications are to a certain extent intrinsically tied to social factors. To empirically examine the impact of sociodemographic factors on patients institutionalized with dementia praecox in the early 20th century, we examined records from Dorothea Dix Hospital (DDH), an asylum in Southeastern United States. Data was extracted from digitally archived handwritten admission ledgers and general casebooks. Of those institutionalized at DDH between 1896-1917, 190 patients were diagnosed with dementia praecox. Clinical characteristics of patients are described using descriptive text analysis. We used regression models to examine the influence of sociodemographic factors on length of stay and release condition from the asylum. Race was not recorded for any patient and presumed White since DDH was not racially integrated until 1960s. Women had a significantly increased odds (OR = 3.8, p = 0.016) of dying in the facility than getting discharged; being single significantly increased the odds of dying in the facility (OR = 6.8, p = 0.002). Marital status predicted length of stay-being single increased the length of stay (b = 5.97, t (159) = 2.43, p = 0.016) adjusting for the effects of gender, age, and education. We report the impact of gender and marital status on patient release condition and length of stay in an asylum in the early 20th century. Results from the historical data we empirically examined are relevant today as women continue to experience disparities in mental health care. Family support was crucial to better outcomes then, as it is today.

RESUMO

Substance use disorders (SUDs) are complex brain disorders with heritability rooted in the interplay of multiple genetic factors, alongside significant environmental influences. Gaining insights into the genetic mechanisms that heighten SUD risk can guide precision care, specifically in the development of targeted tools for prevention, early intervention, and the discovery of therapeutic targets. Nurses are ideally placed to advance genomics-informed precision care for individuals with SUDs. To fulfill this role, they must be adequately prepared to assess the value and utility of current genomics knowledge, its limitations, and ways to incorporate this understanding into clinical practice, education, research, and health care policy.

RESUMO

This study aimed to describe the perception of the meaning of life and coping strategies of 19 patients with cancer at a public hospital in Brazil. This is descriptive and qualitative research that used Amedeo Giorgi's phenomenological model, and the interpretation was performed in light of Viktor Frankl's theory. Two themes have emerged: (1) the perception of the meaning of life in the experience with cancer and (2) religious coping to fight the disease. This study showed that revealing the meaning of life in the cancer experience contributes to better treatment compliance, a more favorable view of the future and better quality of life. On the other hand, religious coping is the strategy most used by patients who believe in God, showing a greater state of psychological and spiritual well-being.

RESUMO

BACKGROUND & AIMS: Acute kidney injury (AKI) in cirrhosis is common and associated with high morbidity, but the incidence rates of different etiologies of AKI are not well described in the US. We compared incidence rates, practice patterns, and outcomes across etiologies of AKI in cirrhosis. METHODS: We performed a retrospective cohort study of 11 hospital networks, including consecutive adult patients admitted with AKI and cirrhosis in 2019. The etiology of AKI was adjudicated based on pre-specified clinical definitions (prerenal/hypovolemic AKI, hepatorenal syndrome [HRS-AKI], acute tubular necrosis [ATN], other). RESULTS: A total of 2,063 patients were included (median age 62 [IQR 54-69] years, 38.3% female, median MELD-Na score 26 [19-31]). The most common etiology was prerenal AKI (44.3%), followed by ATN (30.4%) and HRS-AKI (12.1%); 6.0% had other AKI, and 7.2% could not be classified. In our cohort, 8.1% of patients received a liver transplant and 36.5% died by 90 days. The lowest rate of death was observed in patients with prerenal AKI (22.2%; p <0.001), while death rates were higher but not significantly different from each other in those with HRS-AKI and ATN (49.0% vs. 52.7%; p = 0.42). Using prerenal AKI as a reference, the adjusted subdistribution hazard ratio (sHR) for 90-day mortality was higher for HRS-AKI (sHR 2.78; 95% CI 2.18-3.54; p <0.001) and ATN (sHR 2.83; 95% CI 2.36-3.41; p <0.001). In adjusted analysis, higher AKI stage and lack of complete response to treatment were associated with an increased risk of 90-day mortality (p <0.001 for all). CONCLUSION: AKI is a severe complication of cirrhosis. HRS-AKI is uncommon and is associated with similar outcomes to ATN. The etiology of AKI, AKI stage/severity, and non-response to treatment were associated with mortality. Further optimization of vasoconstrictors for HRS-AKI and supportive therapies for ATN are needed. IMPACT AND IMPLICATIONS: Acute kidney injury (AKI) in cirrhosis carries high morbidity, and management is determined by the etiology of injury. However, a large and well-adjudicated multicenter database from US centers that uses updated AKI definitions is lacking. Our findings demonstrate that acute tubular necrosis and hepatorenal syndrome have similar outcomes (∼50% mortality at 90 days), though hepatorenal syndrome is uncommon (12% of all AKI cases). These findings represent practice patterns at US transplant/tertiary centers and can be used as a baseline, presenting the situation prior to the adoption of terlipressin in the US.

RESUMO

BACKGROUND: It is estimated that atrial fibrillation (AF) affects approximately 1.5 million people in Brazil; however, epidemiological data are limited. We sought to evaluate the characteristics, treatment patterns, and clinical outcomes in patients with AF in Brazil by creating the first nationwide prospective registry. METHODS: RECALL was a multicenter, prospective registry that included and followed for 1 year 4,585 patients with AF at 89 sites across Brazil from April 2012 to August 2019. Patient characteristics, concomitant medication use, and clinical outcomes were analyzed using descriptive statistics and multivariable models. RESULTS: Of 4,585 patients enrolled, the median age was 70 (61, 78) years, 46% were women, and 53.8% had permanent AF. Only 4.4% of patients had a history of previous AF ablation and 25.2% had a previous cardioversion. The mean (SD) CHA2DS2-VASc score was 3.2 (1.6); median HAS-BLED score was 2 (2, 3). At baseline, 22% were not on anticoagulants. Of those taking anticoagulants, 62.6% were taking vitamin K antagonists and 37.4% were taking direct oral anticoagulants. The primary reasons for not using an oral anticoagulant were physician judgment (24.6%) and difficulty in controlling (14.7%) or performing (9.9%) INR. Mean (SD) TTR for the study period was 49.5% (27.5). During follow-up, the use of anticoagulants and INR in the therapeutic range increased to 87.1% and 59.1%, respectively. The rates/100 patient-years of death, hospitalization due to AF, AF ablation, cardioversion, stroke, systemic embolism, and major bleeding were 5.76 (5.12-6.47), 15.8 (14.6-17.0), 5.0 (4.4-5.7), 1.8 (1.4-2.2), 2.77 (2.32-3.32), 1.01 (0.75-1.36), and 2.21 (1.81-2.70). Older age, permanent AF, New York Heart Association class III/IV, chronic kidney disease, peripheral arterial disease, stroke, chronic obstructive pulmonary disease, and dementia were independently associated with increased mortality while the use of anticoagulant was associated with lower risk of death. CONCLUSIONS: RECALL represents the largest prospective registry of patients with AF in Latin America. Our findings highlight important gaps in treatment, which can inform clinical practice and guide future interventions to improve the care of these patients.

RESUMO

The number of kidney after liver transplants (KALT) increased after the implementation of the United Network of Organ Sharing (UNOS) safety net policy, but the effects of the policy on KALT outcomes remain unknown. Using the UNOS database, we identified KALT between 60 and 365 days from liver transplant from January 1, 2010, to December 31, 2020. The main outcome was 1- and 3-year patient, liver, and kidney graft survival. Secondary outcomes included 6-month and 1-year acute rejection (AR) of liver and kidney, and 1-year kidney allograft function. Of the 256 KALT, 90 were pre-policy and 166 post-policy. Compared to pre-policy, post-policy 1- and 3-year liver graft survival was higher (54% and 54% vs. 86% and 81%, respectively, p <0.001), while 1- and 3-year kidney graft survival (99% and 75% vs. 92% and 79%, respectively, p =0.19), and 1- and 3-year patient survival (99% and 99% vs. 95% and 89%, respectively, p =0.11) were not significantly different. Subgroup analysis revealed similar trends in patients with and without renal failure at liver transplant. Liver AR at 6 months was lower post-policy (6.3% vs. 18.3%, p =0.006) but was similar (10.5% vs. 13%, p =0.63) at 1 year. Kidney AR was unchanged post-policy at 6 months and 1 year. Creatinine at 1 year did not differ post-policy versus pre-policy (1.4 vs. 1.3 mg/dL, p =0.07) despite a higher proportion of deceased donors, higher Kidney Donor Profile Index, and longer kidney cold ischemia time post-policy ( p <0.05 for all). This 3-year follow-up after the 2017 UNOS policy revision demonstrated that the safety net implementation has resulted in improved liver outcomes for patients who underwent KALT with no increased AR of the liver or the kidney allografts.

RESUMO

The Negishi coupling is a significant C-C bond-forming reaction to access synthetically valuable organic compounds. In recent years, researchers have developed sustainable first-row transition metal (Fe, Co, Ni and Cu) based complexes in place of the conventional Pd catalyst for this reaction. Several such low-cost metal-based catalysts showed high efficiency and potential application in natural product synthesis. This review focuses on the recent achievements in low-cost transition metal-based Negishi coupling reactions, covering reports from 2016.

RESUMO

Tropical Bovine Theileriosis, caused by the protozoan parasite Theileria annulata, poses a significant threat to cattle populations. Currently, Buparvaquone is the sole effective naphthoquinone drug commercially available for its treatment. In our research, we delved into the potential of naturally occurring quinones as alternative treatments. We isolated two quinones, emodin and chrysophanol, from Rheum emodi Wall, and two more, embelin and lawsone, from Embelia ribes Burm.f. and Lawsonia inermis L. respectively. We assessed the anti-Theileria efficacy of these quinones in vitro using MTT and flow cytometric assays on T. annulata-infected bovine lymphocytes. Additionally, we evaluated their safety on uninfected bovine Peripheral Blood Mononuclear Cells (PBMC) and Vero cells. Emodin emerged as a promising candidate, exhibiting an IC50 value of 4 µM, surpassing that of buparvaquone. Emodin also displayed relatively low LD50 values of 1.74 mM against uninfected PBMC and 0.87 mM against Vero cells, suggesting potential safety. Remarkably, emodin demonstrated a high cell absorption rate of 71.32%. While emodin's efficacy and bioavailability are encouraging, further research is imperative to validate its safety and effectiveness for treating Tropical Bovine Theileriosis.

RESUMO

It is estimated that approximately 4.3 million sexually active persons worldwide will receive poor and/or limited access to Sexual and Reproductive Health (SRH) services in their lifetime. Globally, approximately 200 million women and girls still endure female genital cutting, 33,000 child marriages occur daily, and a myriad of Sexual and Reproductive Health and Rights (SRHR) agenda gaps continue to remain unaddressed. These gaps are particularly pertinent for women and girls in humanitarian settings where SRH conditions including gender-based violence, unsafe abortions, and poor obstetric care are among the leading causes of female morbidity and mortality. Notably, the past decade has featured a record high number of forcibly displaced persons globally since World War II and has led to over 160 million persons requiring humanitarian aid globally, 32 million of whom are women and girls of reproductive age. Inadequate SRH service delivery continues to persist in humanitarian settings, with basic services insufficient or inaccessible, putting women and girls at higher risk for increased morbidity and mortality. This record number of displaced persons and the continued gaps that remain unaddressed pertaining to SRH in humanitarian settings require renewed urgency to create upstream solutions to this complex issue. This commentary discusses the gaps in the holistic management of SRH in humanitarian settings, explores why these gaps persist, and addresses the unique cultural, environmental, and political conditions which contribute to continued SRH service delivery inadequacies and increased morbidity and mortality for women and girls.

RESUMO

Low uptake of family planning among women is predominantly attributed to low participation of men in postpartum family planning. In order to improve maternal health, strengthening male participation in family planning is an important public health initiative. This study aimed to assess factors associated with participation of men in postpartum care at Kiswa Health Centre III, Nakawa division, Kampala. An analytical cross-sectional study design involving collection of quantitative data was used. Systematic random sampling was used to select study participants. Data was collected using semi-structured questionnaires. Data entry and cleaning was performed using EpiData version 12 and analysed using Stata version 14. 80.0% of respondents participated in postpartum family planning. Approval of family planning use, knowledge on family planning and information source were significantly associated with male involvement in postpartum family planning. Respondents who approved family planning use at home were 15.5 times more likely to get involved in family planning services as compared to those who didn't approve family planning. Conclusively, there was a generally high level of male involvement in postpartum family planning in comparison with the national levels. Approval of family planning at home increased the likelihood of men's participation in family planning.IMPACT STATEMENTWhat is already known on this subject? Evidence has it that short birth intervals of less than 15 months have been found to be associated with adverse pregnancy outcomes including induced abortions, miscarriages, preterm births, neonatal and child mortalities, still births and maternal depletion syndrome. In Africa, generally, low family uptake among women is also attributed to low men participation in postpartum family planning.What do the results of this study add? Approval of family planning use, knowledge on family planning and information source were associated with male involvement in postpartum family planning. Respondents who approved family planning use at home were 15.5 times more likely to get involved in postpartum family planning services as compared to those who didn't approve family planning.What are the implications of these findings for clinical practice and/or further research? In this study, the involvement of men was relatively high, but more studies are needed in other locations to compare with this finding. Otherwise, consolidation of such high involvement is highly needed, as this can be a starting point for further improvement.

RESUMO

Accurate diagnosis and appropriate treatment of tardive dyskinesia (TD) are imperative, as its symptoms can be highly disruptive to both patients and their caregivers. Misdiagnosis can lead to incorrect interventions with suboptimal or even deleterious results. To aid in the identification and differentiation of TD in the psychiatric practice setting, we review its clinical features and movement phenomenology, as well as those of other antipsychotic-induced movement disorders, with accompanying links to illustrative videos. Exposure to dopamine receptor blocking agents (DRBAs) such as antipsychotics or antiemetics is associated with a spectrum of movement disorders including TD. The differential diagnosis of TD is based on history of DRBA exposure, recent discontinuation or dose reduction of a DRBA, and movement phenomenology. Common diagnostic challenges are the abnormal behaviors and dyskinesias associated with advanced age or chronic mental illness, and other movement disorders associated with DRBA therapy, such as akathisia, parkinsonian tremor, and tremor related to use of mood stabilizing agents (eg, lithium, divalproex). Duration of exposure may help rule out acute drug-induced syndromes such as acute dystonia or acute/subacute akathisia. Another important consideration is the potential for TD to present together with other drug-induced movement disorders (eg, parkinsonism, parkinsonian tremor, and postural tremor from mood stabilizers) in the same patient, which can complicate both diagnosis and management. After documentation of the phenomenology, severity, and distribution of TD movements, treatment options should be reviewed with the patient and caregivers.

RESUMO

Pollution by microplastics (MPs) formed by the physicochemical breakdown of plastics are a worldwide issue with long-lasting and hazardous natural effects. The natural expulsion of MPs takes several years and can be dangerous. Several effective technological innovations have been developed over the years to remediate harmful MPs. Among them, a blend of nanotechnological techniques using bionanomaterials has been investigated to a large extent. The objective of this review is to compile the MPs found in the environment and bionanomaterial-based approaches for their removal. This information is important for researchers who are exploring the adverse consequences of MPs and their remediation and developing advanced eco-friendly strategies to control and eradicate MPs in the future. The control and eradication of MPs depend on all of us; hence, the proper awareness of MPs pollution must be provided to every individual, as all of us are a part of the environment.

RESUMO

We emphasize the benefits of a multidisciplinary team approach to the systemic management of patients with cleft lip and cleft palate (CL/CP) and their families. An ideal team offers support to families at each stage of their child's development and adapts to address new issues that are encountered throughout growth. We suggest the addition of a registered dietitian to the initial phase of the care team to ensure the child consumes adequate macronutrient intake, and to maximize growth and development. An ideal cleft palate care team focuses on a comprehensive, collaborative, and family-centered approach to the complex medical and surgical needs of infants with CL/CP as they grow to young adulthood. Although care teams may differ slightly depending on context and location, there are central tenets that make an ideal team. After reviewing CL/CP care team guidelines and recommendations from a variety of different countries, this article reflects what an ideal organization structure and care team composition could be comprised of.

RESUMO

Each year, over 200 million women globally cannot prevent pregnancy through modern contraceptive methods, with 70-80% of these women residing in sub-Saharan Africa. Consequently, almost 50% of pregnancies are unintended and 35 million unsafe abortions occur annually in the region. Further, sub-Saharan Africa has the highest burden globally of Human Immune-Deficiency Virus (HIV) infection, and over 57% of those affected are women. Women with a positive HIV status in sub-Saharan Africa experience higher rates of unintended pregnancy and unsafe abortion practices. In this commentary, we propose strategies to strengthen integrated sexual and reproductive health and rights (SRHR) and HIV services programs to improve the sexual and reproductive health of girls and women and to work towards achieving SDGs 3 and 5 in sub-Saharan Africa. We suggest a focus on capacity building, strengthening intersectoral collaborations, and improving governance and financial investment.

RESUMO

PURPOSE OF REVIEW: Among the most common causes of cardiac syncope are arrhythmias and ischemic heart disease, both of which can coexist. The purpose of this review is to discuss the main causes of cardiac and vascular syncope related to atherosclerosis, its epidemiological and clinical aspects, warning signs, and initial approach. RECENT FINDINGS: Cardiac syncope may have a frequency of up to 34% in elderly people. Atherosclerosis-related causes of cardiac and vascular syncope may be due to cardiac arrhythmia and/or structural impairment of the heart or arteries. Late ventricular tachycardia and late-onset high-grade atrioventricular block associated with myocardial ischemia may occur with syncope, which is related to higher mortality. Besides ventricular dysfunction, concentric remodeling is also a prognostic factor. In calcific degenerative aortic stenosis, syncope carries a worse prognosis than the other cardinal signs. Cardiac syncope has a high recurrence and mortality rate. There are red flag alerts that must be considered in risk stratification.

RESUMO

BACKGROUND: There are controversial results about the effects of cancer and chemotherapy on the perception of distress. AIMS: The purpose to the study is to explore the meaning of the distress experienced by patients with cancer and verify whether the cancer diagnosis, stage and receiving chemotherapy influence this experience. DESIGN: This is a mixed-methods study with cancer patients. METHODS: Data were collected in 2018 using a phenomenological interview (n = 18) and one suffering inventory (n = 100). Qualitative analysis was performed using the empirical-comprehensive model and quantitative using statistical tests. The results were triangulated. RESULTS: Distress originated from difficulties faced in health services, diagnosis confirmation, beginning treatment and interruption of life projects. Patients mobilized resources in the spiritual dimension that allowed them to redefine their distress positively. Chemotherapy brought hope back and promoted healing expectations. Higher average scores for distress were found in patients with advanced stage and receiving palliative chemotherapy. Not having begun chemotherapy and having head and neck cancer were associated with higher average scores for distress. CONCLUSION: Distress was greater among patients who had not yet begun chemotherapy; nearness of death and difficulty talking about feelings caused distress; distress was redefined by mobilization of spiritual resources.
