RESUMO

Although it is well established that fibromyalgia (FM) syndrome is characterized by chronic diffuse musculoskeletal hyperalgesia, very little is known about the effect of this pathology on muscle tissue plasticity. Therefore, the present study aimed to characterize the putative alterations in skeletal muscle mass in female rats subjected to a FM model by inducing chronic diffuse hyperalgesia (CDH) through double injections of acidic saline (pH 4.0) into the left gastrocnemius muscle at 5-day intervals. To determine protein turnover, the total proteolysis, proteolytic system activities and protein synthesis were evaluated in oxidative soleus muscles of pH 7.2 (control) and pH 4.0 groups at 7 days after CDH induction. All animals underwent behavioural analyses of mechanical hyperalgesia, strength and motor performance. Our results demonstrated that, in addition to hyperalgesia, rats injected with acidic saline exhibited skeletal muscle loss, as evidenced by a decrease in the soleus fibre cross-sectional area. This muscle loss was associated with increased proteasomal proteolysis and expression of the atrophy-related gene (muscle RING-finger protein-1), as well as reduced protein synthesis and decreased protein kinase B/S6 pathway activity. Although the plasma corticosterone concentration did not differ between the control and pH 4.0 groups, the removal of the adrenal glands attenuated hyperalgesia, but it did not prevent the increase in muscle protein loss in acidic saline-injected animals. The data suggests that the stress-related hypothalamic-pituitary-adrenal axis is involved in the development of hyperalgesia, but is not responsible for muscle atrophy observed in the FM model induced by intramuscular administration of acidic saline. Although the mechanisms involved in the attenuation of hyperalgesia in rats injected with acidic saline and subjected to adrenalectomy still need to be elucidated, the results found in this study suggest that glucocorticoids may not represent an effective therapeutic approach to alleviate FM symptoms.

RESUMO

OBJECTIVES: Analyze and verify the association between working conditions and the occurrence of errors in nursing work. BACKGROUND: Many of the known errors in nursing are based on the structural failure of the complex health service system. Our study addresses the question "Is there an association between errors made by nursing workers and working conditions?" METHODS: The study was carried out through a cross-sectional exploratory analysis of 19 ethical-disciplinary processes focused on errors made by nursing workers. The articles were processed, judged, and archived at the Regional Nursing Councils of the Northeast Region of Brazil from 2000 to 2018. The chi-square test or Fisher's exact test was used to verify the relationship between the variables through multivariate analysis. RESULTS: The analyzes show that working conditions can interfere at occurrence in error. This increases the chance of an "inconsequential" error occurring for the patient in poor/very poor working conditions. The most serious errors, "with consequences irreversible" for the patient, only occur from more severe working conditions. Adversely, it was found that there is no statistically significant difference in the frequency of errors in hospitals (33.33 %) compared to "other places" (28.58 %) when these occurred in poor working conditions. When conducting the incident in poor working conditions, there was a minimum of 52 % protection OR = 0.48 % [0.16; 11.80]; (1-0.48)) against these errors in general in the nursing area. CONCLUSION: The strong association was exposed in working conditions classified as bad/very bad/very bad, resulting in the most serious errors and with irreversible consequences for patients. However, a level of protection for different types of workers was noticed in the field, which shows that there is hope that if the work environment changes with more organization, management, and standards of care, we can prevent future errors.

RESUMO

GOAL: The COVID-19 pandemic has caused both short- and long-term impacts on every aspect of society. Hospitals are among the most critical frontliners and have had to continually navigate the challenges caused by the pandemic. In this study, we examined hospitals' financial performance following the onset of the pandemic. METHODS: We used data from the Centers for Medicare & Medicaid Services Healthcare Cost Report Information System. The study sample included all general acute care and critical access hospitals that receive Medicare payments. The primary outcomes included operating margins, net patient revenues, operating expenses, and uncompensated care costs. We tested for average changes from 2019 to 2020 in hospitals' financial outcomes. We also tested for changes in financial outcomes across samples stratified by hospital characteristics: ownership type (investor-owned, nonprofit, and public), Medicaid disproportionate share hospital status, rural status, county uninsured rate quartile, and Medicaid expansion status. PRINCIPAL FINDINGS: Our sample consisted of a balanced panel of 4,059 hospitals (8,118 observations) with data spanning 2019 and 2020. Across the full sample of hospitals, operating margins declined by an average of 5.3 percentage points between 2019 and 2020, equating to a 130% reduction from 2019 levels. Underlying these margin declines, net patient revenues declined by 3.2% on average, while operating expenses increased by 1.5%. We observed no changes in uncompensated care costs despite the large number of job losses that accompanied the pandemic. When stratifying the analysis by hospital characteristics, differences were observed across ownership types. Notably, investor-owned facilities were less affected financially than nonprofit and public hospitals. Although safety-net and rural hospitals generally fared no worse than their non-safety-net and nonrural counterparts, hospitals located in Medicaid expansion states experienced steeper declines in operating margins relative to hospitals located in nonexpansion states, driven by larger relative declines in patient revenues. PRACTICAL APPLICATIONS: The operating margin declines we observed can be attributed to supply-chain issues, persistent labor shortages, and suspension of elective services. The Affordable Care Act reforms in health insurance markets likely helped to insulate hospitals from increases in uncompensated care costs. In the shifting context of the pandemic, it is important to understand hospitals' financial performance so that measures can be taken to address further financial distress that may eventually lead to increased consolidation, hospital closures, and lower quality of care. Our findings stress the need for targeted responses that are tailored to underlying hospital characteristics. Temporary and targeted increases in inpatient and outpatient service prices can help offset revenue losses from the deferment of nonurgent care. Other policies can address the ongoing workforce challenges and supply-chain issues.

RESUMO

This study was carried out to evaluate the effects of supplementation with different levels of copper (Cu) and zinc (Zn), using two mineral sources (sulphate and hydroxy forms), on the bone characteristics, skin strength/elasticity, and haematological parameters of broilers. A total of 1792 1-day-old male Cobb-500 broiler chickens were randomly distributed among eight dietary treatments, using Cu sulphate (CSM) or hydroxychloride (CHC), and Zn sulphate (ZSM) or hydroxychloride (ZHC). The dietary treatments were as follows: (1) low-CSM/high-ZSM, (2) high-CSM/high-ZSM, (3) low-CHC/low-ZHC, (4) low-CHC/medium-ZHC, (5) low-CHC/high-ZHC, (6) high-CHC/low-ZHC, (7) high-CHC/medium-ZHC, and (8) high-CHC/high-ZHC. On Day 42, blood samples were collected from one bird/pen to analyze the haematological parameters. Finally, two birds/pen were slaughtered, and the tibia and femur were collected to analyze the quality of bone and skin. The means were subjected to ANOVA and, when significant, compared by Tukey's test (p < 0.05) or Dunnett's (p < 0.05) test. The haematological parameters were not influenced by mineral supplementation. However, the inclusion of low ZHC enhanced the skin strength compared to high ZHC (p = 0.046). Furthermore, the bone mineral density of the tibia proximal epiphysis, tibia ash and tibia mineral content were positively improved with supplementation of low-CHC/medium-ZHC compared to high-CHC/medium-ZHC. This study demonstrated that hydroxy compounds are potential alternatives for replacing sulphate supplements in broiler diets. Moreover, among the Cu and Zn levels, the low CHC (15 mg/kg) and medium ZHC (100 mg/kg) improved bone development and skin integrity, suggesting that the combination of Cu and Zn can be a nutritional strategy to prevent the incidence of leg disorders in broilers.

RESUMO

Drought is one of the main environmental stresses that negatively impacts vegetative and reproductive yield. Water deficit responses are determined by the duration and intensity of the stress, which, together with plant genotype, will define the chances of plant survival. The metabolic adjustments in response to water deficit are complex and involve gene expression modulation regulated by DNA-binding proteins and epigenetic modifications. This last mechanism may also regulate the activity of transposable elements, which in turn impact the expression of nearby loci. Setaria italica plants submitted to five water deficit regimes were analyzed through a phenotypical approach, including growth, physiological, RNA-seq and sRNA-seq analyses. The results showed a progressive reduction in yield as a function of water deficit intensity associated with signaling pathway modulation and metabolic adjustments. We identified a group of loci that were consistently associated with drought responses, some of which were related to water deficit perception, signaling and regulation. Finally, an analysis of the transcriptome and sRNAome allowed us to identify genes putatively regulated by TE- and sRNA-related mechanisms and an intriguing positive correlation between transcript levels and sRNA accumulation in gene body regions. These findings shed light on the processes that allow S. italica to overcome drought and survive under water restrictive conditions.

RESUMO

BACKGROUND: Peripheral artery disease (PAD) disproportionately affects nonwhite, Hispanic/Latino, and low socioeconomic status patients, who are less likely to have insurance and routine healthcare visits. Medicaid expansion (ME) has improved insurance rates and access to care, potentially benefitting these patients. We sought to assess the impact of ME on disparities in outcomes after peripheral vascular intervention (PVI) for PAD. METHODS: A retrospective analysis of prospectively-collected Vascular Quality Initiative PVI procedures between 2011 and 2019 was conducted. The sample was restricted to first-record procedures in adults under the age 65 in states that expanded Medicaid on January 1, 2014 (ME group) or had not expanded before January 1, 2019 (non-expansion [NE] group). ME and NE groups were compared between pre-expansion (2011-2013) and post-expansion (2014- 2019) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors and clinical center and year fixed effects. Our primary outcome was 1-year major amputation. Secondary outcomes included trends in presentation, 30-day mortality, 1-year mortality, and 1-year primary and secondary patency. Outcomes were stratified by race and ethnicity. RESULTS: We examined 34,313 PVI procedures, including 20,378 with follow-up data. Rates of Medicaid insurance increased post-expansion in ME and NE states (ME 16.7% to 23.0%, P < 0.001; NE 10.0% to 11.9%, P = 0.013) while rates of self-pay decreased in ME states only (ME 4.6% to 1.8%, P < 0.001; NE 8.1% to 8.4%, P = 0.620). Adjusted difference-in-differences analysis revealed lower odds of urgent/emergent PVI among all patients and all nonwhite patients in ME states post-expansion compared to NE states (all: odds ratio [OR] 0.53 [95% confidence interval 0.33-0.87], P = 0.011; nonwhite: OR 0.41 [0.19-0.88], P = 0.023). No differences were observed for 1-year major amputation (OR 0.70 [0.43-1.14], P = 0.152), primary patency (OR 0.93 [0.63-1.38], P = 0.726), or secondary patency (OR 1.29 [0.69-2.41], P = 0.431). Odds of 1-year mortality were higher in ME states post-expansion compared to NE states (OR 2.50 [1.07-5.87], P = 0.035), although 30-day mortality was not different (OR 2.04 [0.60-6.90], P = 0.253). Notably, odds of 1-year major amputation among Hispanic/Latino patients decreased in ME states post-expansion compared to NE states (OR 0.11 [0.01-0.86], P = 0.036). CONCLUSIONS: ME was associated with lower odds of 1-year major amputation among Hispanic/Latino patients who underwent PVI for PAD. ME was also associated with lower odds of urgent/emergent procedures among patients overall and nonwhite patients specifically. However, 1-year mortality increased in the overall cohort. Further study is needed to corroborate our findings that ME may have benefits for certain underserved populations with PAD.

RESUMO

BACKGROUND: Nonprofit hospitals (NFPs) are required to provide community benefits, which have been historically focused on provision of medical care, to keep their tax exemption status. To increase hospital investment in community health, the Patient Protection and Affordable Care Act required NFPs to conduct community health needs assessments and address identified needs. Some states have leveraged this provision to encourage collaboration between NFPs and local health departments (LHDs) in local health planning. OBJECTIVE: The objective of this study was to examine the association of NFP-LHD collaboration in local health planning targeting drug use, with drug-induced mortality. RESEARCH DESIGN: We conducted difference-in-differences analyses using drug-induced mortality data from 2009 to 2016, encompassing the first 3 years after NFP-LHD collaboration in local health planning specific to drug use. We evaluated drug-induced mortality in 22 counties in which collaboration was required in comparison with that in 198 control counties. We used data collected from implementation strategy reports by NFPs and combined it with data on hospital characteristics, as well as state-level and county-level factors associated with drug-induced mortality. MEASURES: The primary outcome was county-level drug-induced mortality per 100,000 population. RESULTS: Counties, in which NFP-LHD collaboration in local health planning was required and in which NFPs and LHDs jointly prioritized drug use, experienced a deceleration in drug-induced mortality of ~8 deaths per 100,000 population compared with the mortality rate they would have experienced without collaboration. CONCLUSIONS: Collaboration between NFPs and LHDs to address drug use was associated with a deceleration in drug-induced mortality. Policymakers can leverage community benefit regulation to encourage NFP-LHD collaboration in local health planning.

RESUMO

BACKGROUND: The patient protection and Affordable Care Act (ACA) sought to improve population health by requiring nonprofit hospitals (NFPs) to conduct triennial community health needs assessments and address the identified needs. In this context, some states have encouraged collaboration between hospitals and local health department (LHD) to increase the focus of community benefit spending onto population health. OBJECTIVES: The aim was to examine whether a 2012 state law that required NFPs to collaborate with LHDs in local health planning influenced hospital population health improvement spending. RESEARCH DESIGN: We merged Internal Revenue Service data on NFP community benefit spending with data on hospital, county and state-level characteristics and estimated a difference-in-differences specification of hospital population health spending in 2009-2016 that compared the difference between hospitals that were required to collaborate with LHDs to those that were not, before and after the requirement. MEASURES: The primary outcome was population health spending divided by operating expenses. RESULTS: We found that the requirement for hospital-LHD collaboration was associated with increased mean population health spending of ∼$393,000-$786,000 (P=0.03). This association was significant in 2015-2016, perhaps reflecting the lag between assessments and implementation. Urban hospitals were responsible for most of the increased spending. CONCLUSIONS: Policymakers have sought to encourage hospitals to increase their investment in population health; however, overall community benefit spending on population health has remained flat. We found that requiring hospital-LHD collaboration was associated with increased hospital investment in population health. It may be that hospitals increase population health spending because collaboration improves expected effectiveness or increases hospital accountability.

RESUMO

Two-dimensional (2D) materials offer an ideal platform to study the strain fields induced by individual atomic defects, yet challenges associated with radiation damage have so far limited electron microscopy methods to probe these atomic-scale strain fields. Here, we demonstrate an approach to probe single-atom defects with sub-picometer precision in a monolayer 2D transition metal dichalcogenide, WSe2-2xTe2x. We utilize deep learning to mine large data sets of aberration-corrected scanning transmission electron microscopy images to locate and classify point defects. By combining hundreds of images of nominally identical defects, we generate high signal-to-noise class averages which allow us to measure 2D atomic spacings with up to 0.2 pm precision. Our methods reveal that Se vacancies introduce complex, oscillating strain fields in the WSe2-2xTe2x lattice that correspond to alternating rings of lattice expansion and contraction. These results indicate the potential impact of computer vision for the development of high-precision electron microscopy methods for beam-sensitive materials.

RESUMO

The objective of this study was to evaluate the productive performance and quality of eggs and bones of Japanese quails that received different dietary electrolyte balance (EB) and were submitted to thermoneutrality or heat stress conditions. Eight hundred Japanese quails of 21 days of age were selected and distributed randomly in two bioclimatic chambers: thermoneutral chamber (23 °C ± 2 °C) and heat-stress chamber (33 °C ± 2 °C). The treatments were in a 2 × 5 factorial arrangement, with two temperatures and five EB levels (165, 215, 265, 315, 365 mEq/kg) with four replicates of 20 birds each. The productive performance and egg quality (in 3 cycles of 21 days) were measured. At 105 days old, the bone quality was evaluated. Data were analyzed by Minitab, and the means were compared by Tukey's test and regression test for levels (P < 0.05). Quails submitted to thermoneutrality showed better performance and egg and bone quality. The highest production rate was the EB level of 265 mEq/kg. Low values of EB (165 and 215 mEq/kg) and high values (365) impaired egg quality, and the ideal was 315 mEq/kg. Lower levels of balance provided poor bone density. In conclusion, the results of this study indicated that heat stress impairs the production and quality of quail eggs and bones. Furthermore, by using intermediate EB levels (265 and 315) mEq/kg, it is possible to improve egg production and egg quality, and using high levels increases bone mineral density.

RESUMO

OBJECTIVE: To determine the association of state laws on nonprofit hospital community benefit spending. DESIGN: We used multivariate models to estimate the association between different types of state-level community benefit laws and nonprofit hospital community benefit spending from tax filings. SETTING: All 50 US states. PARTICIPANTS: A total of 2421 nonprofit short-term acute care hospital organizations that filled an internal revenue service Form 990 and Schedule H for calendar during years 2009-2015. RESULTS: Between 2009 and 2015, short-term acute care hospitals spent an average of $46 billion per year in total, or $20 million per hospital on community benefit activities. Exposure to a state-level community benefit law of any type was associated with an $8.42 (95% confidence interval: 1.20-15.64) per $1000 of total operating expense greater community benefit spending. Spending amounts and patterns varied on the basis of the type of community benefit law and hospital urbanicity. CONCLUSIONS: State laws are associated with nonprofit hospital community benefit spending. Policy makers can use community benefit laws to increase nonprofit hospital engagement with public health.

RESUMO

In 1990, the first Teratogen Information Service in Brazil (SIAT) was implemented in the Medical Genetics Service at Hospital de Clinicas de Porto Alegre. SIAT is a free-to-use information service both to health professionals and the general population, especially to women who are pregnant or planning pregnancy. The main objective of this paper is to present the activities of SIAT in its initial years (1990-2006), compared to those in the last decade (2007-2017). In addition we review the scientific contribution of SIAT in the field of human teratogenesis. Since 1990, SIAT received 10,533 calls. Use of medications were the main reason for concern, accounting for 74% of all questions, followed by other chemical exposures (occupational, cosmetics, environmental), and maternal infectious diseases. Among its main contributions to scientific knowledge was the collaboration for the identification of two new human teratogens: misoprostol in the 1990s and Zika virus in 2015/16. In conclusion, SIAT is still evolving, as is the Medical Genetics Service that hosts it. Through its 27 years of existence more than 300 undergraduate and graduate students have rotated at SIAT. Presently, SIAT is expanding the research to experimental teratogenesis and to investigation of molecular mechanisms of teratogens.

RESUMO

OBJECTIVE: To identify the contribution of all the dimensions involved in job insecurity among nursing professionals in Brazilian state public hospitals. METHOD: This was a quantitative descriptive study conducted between March 2015 and February 2016, with nurses, nursing technicians and nursing aides. The data were analyzed using exploratory factor analysis. RESULTS: The sample consisted of 265 nurses (n=161 with job security and n=104 outsourced) and 810 nursing technicians and nursing aides (n=597 with job security and n=213 outsourced). Among the nurses, "Working conditions" accounted for 46.8% of their job insecurity. Among nursing technicians and nursing aides "intensity of work due to work process organization" best explained the construct of job insecurity (51.2%). CONCLUSION: Job insecurity is expressed differently depending on the type of nursing professional. The difference in the distribution of the dimensions showed that job insecurity is related to the hierarchical position of each nursing professional in the technical division of nursing work and the role of each professional in the work process.

RESUMO

Fungal Candida species are commensals present in the mammalian skin and mucous membranes. Candida spp. are capable of breaching the epithelial barrier of immunocompromised patients with neutrophil and cell-mediated immune dysfunctions and can also disseminate to multiple organs through the bloodstream. Here we examined the action of innate defense regulator 1018 (IDR-1018), a 12-amino-acid-residue peptide derived from bovine bactenecin (Bac2A): IDR-1018 showed weak antifungal and antibiofilm activity against a Candida albicans laboratory strain (ATCC 10231) and a clinical isolate (CI) (MICs of 32 and 64 µg · ml-1, respectively), while 8-fold lower concentrations led to dissolution of the fungal cells from preformed biofilms. IDR-1018 at 128 µg · ml-1 was not hemolytic when tested against murine red blood cells and also has not shown a cytotoxic effect on murine monocyte RAW 264.7 and primary murine macrophage cells at the tested concentrations. IDR-1018 modulated the cytokine profile during challenge of murine bone marrow-derived macrophages with heat-killed C. albicans (HKCA) antigens by increasing monocyte chemoattractant protein 1 (MCP-1) and interleukin-10 (IL-10) levels, while suppressing tumor necrosis factor alpha (TNF-α), IL-1ß, IL-6, and IL-12 levels. Mice treated with IDR-1018 at 10 mg · kg-1 of body weight had an increased survival rate in the candidemia model compared with phosphate-buffered saline (PBS)-treated mice, together with a diminished kidney fungal burden. Thus, IDR-1018 was able to protect against murine experimental candidemia and has the potential as an adjunctive therapy.

RESUMO

Introduction Henoch-Schönlein purpura is a multisystem small vessel vasculitis. Neurologic manifestations are uncommon. Posterior reversible encephalopathy syndrome is a rare complication of Henoch-Schönlein purpura with typical clinical and neuroimaging findings that occurs most commonly in the setting of severe hypertension and renal injury. Case presentation A seven-year-old girl was admitted to our institution presenting with clinical and laboratory findings suggestive of Henoch-Schönlein purpura. Glucocorticoid therapy was initiated, but five days following her admission, she developed altered consciousness, seizures, arterial hypertension, and cortical blindness. Brain MRI scan revealed areas of vasogenic oedema in parieto-occipital lobes, consistent with posterior reversible encephalopathy syndrome. She was immediately initiated on antihypertensives and antiepileptics, which successfully improved her neurologic symptoms. Further laboratory work-up disclosed a rapidly progressive glomerulonephritis secondary to Henoch-Schönlein purpura that was the likely cause of her sudden blood pressure elevation. Immunosuppressive therapy was undertaken, and at one-year follow-up, the patient exhibited complete renal and neurologic recovery. Conclusion Posterior reversible encephalopathy syndrome is a severe complication of Henoch-Schönlein purpura. If promptly diagnosed and treated, children with Henoch-Schönlein purpura presenting with posterior reversible encephalopathy syndrome usually have a good prognosis. Clinicians should be familiar with the characteristic presentation of posterior reversible encephalopathy syndrome and be aware that hypertension and renal injury may predispose Henoch-Schönlein purpura patients to developing this complication.

RESUMO

OBJECTIVE: To characterize medication incidents occurred in an outpatient emergency service. METHOD: Descriptive, documental, retrospective and quantitative research. The International Classification for Patient Safety was the theoretical reference for the construction of the instrument used to collect and analyze the data from 119 notification and investigation forms of incidents occurred in 2014 in a teaching hospital. Data were collected twice, compared, corrected and transcribed to an Excel worksheet. The SPSS 19.0 Software and the non-parametric Mann-Whitney test were used in the analysis; p<0.05 indicated statistical significance. RESULTS: A total of 142 incidents were analyzed, most of them involving the nursing team; 93.7% were avoidable; one-third involved high-alert medications; the majority involved parenteral administration. Harm was rare but proportional to the time elapsed for error detection. Management failures prevailed, especially omission. CONCLUSION: Most of the incidents analyzed were characterized as potentially harmful and avoidable, with emphasis on personnel factors as contributors.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the effect of irrigation methods on antibacterial potential of 2.5% NaOCl on Enterococcus faecalis biofilm. MATERIALS AND METHODS: Enterococcus faecalis biofilms were prepared during 60 days on 48 human root canals and randomized into control and experimental groups using positive and negative pressure irrigation. Bacterial growth was analyzed using turbidity of culture medium followed by UV spectrophotometry, and scanning electron microscopy (SEM) analyses were performed. Mean and standard deviations were used for evaluate the mean optical densities associated to the number of bacteria present culture, and Scheirer-Ray-Hare (an extension of the Kruskal-Wallis test) and Tamhane test to analyze the SEM images in the groups and thirds. Significance was set at 5%. RESULTS: Enterococcus faecalis was still present after root canal cleaning regardless of irrigation methods or bacterial identification methods. CONCLUSION: Positive and negative pressure irrigation protocols using 2.5% NaOCl show a similar capacity to reduce E. faecalis in infected root canals.

RESUMO

Importance: To meet increasing demand for mental health and substance use services, the Centers for Medicare & Medicaid Services launched the 5-year Comprehensive Primary Care Plus (CPC+) demonstration in 2017, requiring primary care practices to integrate behavioral health services. Objective: To examine the association of CPC+ with access to mental health and substance use treatment before and during the COVID-19 pandemic. Design, Setting, and Participants: Using difference-in-differences analyses, this retrospective cohort study compared adults attributed to CPC+ and non-CPC+ practices, from January 1, 2018, to June 30, 2022. The study included adults aged 19 to 64 years who had depression, anxiety, or opioid use disorder (OUD) and were enrolled with a private health insurer in Pennsylvania. Data were analyzed from January to June 2023. Exposure: Receipt of care at a practice participating in CPC+. Main Outcomes and Measures: Total cost of care and the number of primary care visits for evaluation and management, community mental health center visits, psychiatric hospitalizations, substance use treatment visits (residential and nonresidential), and prescriptions filled for antidepressants, anxiolytics, buprenorphine, naltrexone, or methadone. Results: The 188 770 individuals in the sample included 102 733 adults (mean [SD] age, 49.5 [5.6] years; 57 531 women [56.4%]) attributed to 152 CPC+ practices and 86 037 adults (mean [SD] age, 51.6 [6.6] years; 47 321 women [54.9%]) attributed to 317 non-CPC+ practices. Among patients diagnosed with OUD, compared with patients attributed to non-CPC+ practices, attribution to a CPC+ practice was associated with filling more prescriptions for buprenorphine (0.117 [95% CI, 0.037 to 0.196] prescriptions per patient per quarter) and anxiolytics (0.162 [95% CI, 0.005 to 0.319] prescriptions per patient per quarter). Among patients diagnosed with depression or anxiety, attribution to a CPC+ practice was associated with more prescriptions for buprenorphine (0.024 [95% CI, 0.006 to 0.041] prescriptions per patient per quarter). Conclusions and Relevance: Findings of this cohort study suggest that individuals with an OUD who received care at a CPC+ practice filled more buprenorphine and anxiolytics prescriptions compared with patients who received care at a non-CPC+ practice. As the Centers for Medicare & Medicaid Innovation invests in advanced primary care demonstrations, it is critical to understand whether these models are associated with indicators of high-quality primary care.

RESUMO

Introduction: Introduction: the dietary intake of individuals with phenylketonuria (PKU) may vary widely according to different cultural eating habits, lifestyle, access to multidisciplinary team, and metabolic formulas available. Thus, knowing the dietary intake of this population makes it possible to tailor nutritional treatment strategies to impact their health. Objective: to analyze the evidence on the dietary intake of individuals with PKU. Methods: an integrative literature review was conducted on the dietary intake of individuals with PKU in the databases PUBMED, BIREME and Science Direct. Original articles that addressed the energy and macronutrient food intake of children, adolescents and/or adults with PKU were included in the study, without time restriction, in any language. A total of 384 articles were found and 27 articles were selected and analyzed. Results: evidence about the nutritional composition of their diet showed that individuals with PKU consume between 1160-2721 kcal of energy -7.2-17.4 % (32.4-76.9 g) of energy as protein, 45.9-69.2 % of energy as carbohydrates, 16.6-39 % of energy as lipids- and between 7.6 and 20 g of fiber. Conclusion: most individuals with PKU have low energy, protein and fiber intake, adequate lipid intake, and high carbohydrate intake. Metabolic control of the disease is still a challenge in all countries. Nutritional strategies to improve dietary nutritional composition and phenylalanine blood levels in individuals with PKU remain an urgent issue.


Introducción: Introducción: la ingesta dietética de los individuos con fenilcetonuria (PKU) puede variar ampliamente debido a los diferentes hábitos culturales de alimentación, el estilo de vida, el acceso al equipo multidisciplinar y las fórmulas metabólicas disponibles. Por ello, conocer la ingesta dietética de esta población permite adaptar las estrategias de tratamiento nutricional para incidir en su salud. Objetivo: analizar la evidencia sobre la ingesta dietética de individuos con PKU. Métodos: se realizó una revisión bibliográfica integradora sobre la ingesta dietética de las personas con PKU en las bases de datos PUBMED, BIREME y Science Direct. El estudio incluyó artículos originales que abordaran la ingesta alimentaria de energía y macronutrientes de niños, adolescentes y/o adultos con PKU, sin restricción de tiempo, en cualquier idioma. Se encontraron 384 artículos y se seleccionaron y analizaron 27. Resultados: la evidencia de la composición nutricional de la dieta mostró que los individuos con PKU consumen entre 1160 y 2721 kcal de energía ­7,2-17,4 % (32,4-76,9 g) de la energía en forma de proteínas, 45,9-69,2 % de la energía en carbohidratos, 16,6-39 % de la energía en lípidos­ y entre 7,6 y 20 g de fibra. Conclusiones: la mayoría de los individuos con PKU tienen una ingesta baja de energía, proteínas y fibra, una ingesta adecuada de lípidos y una ingesta alta de hidratos de carbono. El control metabólico de la enfermedad sigue siendo un reto en todos los países. Siguen siendo urgentes las estrategias nutricionales para mejorar la composición nutricional de la dieta y los niveles de fenilalanina en sangre de los individuos con PKU.
