RESUMO

Objective: To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province. Methods: Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden. Results: From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women. Conclusions: The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.

RESUMO

OBJECTIVES: Frailty has become an independent risk factor for adverse outcomes in critically ill patients. This study aimed to explore the predictive ability of two electronic medical record-based frailty assessment tools, the Hospital Frailty Risk Score (HFRS) and Frailty Index based on physiological and laboratory tests (FI-lab), for long-term adverse prognosis in older critically ill survivors. DESIGN: Retrospective observational study. SETTING AND PARTICIPANTS: 9,082 critically ill survivors aged ≥ 65 years. MEASUREMENTS: The HFRS and the 33-item FI-lab were constructed based on the published literature. Cox and logistic regression models assessed the association between frailty and 1-year mortality and post-discharge care needs. RESULTS: 2,586 patients died within 1 year of follow-up. In fully adjusted models, frailty assessed using both the HFRS (per point, hazard ratio [HR] 1.06, 95% confidential interval [CI] 1.05-1.06; intermediate frailty risk, HR 2.00, 95% CI 1.78-2.25; high frailty risk, HR 3.06, 95% CI 2.68-3.50) and FI-lab (per 0.01 points, HR 1.03, 95% CI 1.03-1.03; intermediate frailty risk, HR 1.59, 95% CI 1.44-1.76; high frailty risk, HR 2.30, 95% CI 2.06-2.57) was associated with mortality. Addition of frailty indicators improved the predictive validity of the Sequential Organ Failure Assessment score for mortality (HFRS alone ∆ C-index 0.034; FI-lab alone ∆ C-index 0.016; HFRS and FI-lab combined ∆ C-index 0.042). The HFRS but not the FI-lab was associated with higher probability of post-discharge care needs. CONCLUSION: Both the HFRS and FI-lab could independently predict 1-year mortality in older critically ill survivors. Adding the HFRS to the SOFA score model improved it more than adding the FI-lab. The greatest improvement was achieved when both frailty indicators were used together. These findings suggest that electronic medical record-based frailty assessment methods can be useful tools for predicting long-term outcomes in older critically ill patients.

RESUMO

STUDY OBJECTIVE: Latino youths in the United States experience disproportionately high rates of teen pregnancy. The aim of this study was to obtain expecting and parenting Latino adolescents' perspectives regarding factors contributing to teen pregnancy and pregnancy prevention. METHODS: Expecting/parenting Latino adolescents were recruited from high schools with high proportions of Latino youths and teen pregnancy. Participants completed a questionnaire on sociodemographic and background characteristics. Focus groups were stratified by age and gender and audio recorded. Grounded theory was used to identify themes from the transcribed audio recordings. RESULTS: Thirty-two expecting/parenting Latino adolescents (20 females, 12 males) 14-19 years old participated in four focus groups. Quantitative results revealed that two-thirds of participants at birth had adolescent mothers. Over three-quarters of participants reported that their pregnancies had occurred too soon. Qualitative themes for factors contributing to teen pregnancy included lack of contraceptive knowledge/access, belief of invincibility, influence within relationships, male decisions on contraceptive use, desire to belong among peers, lack of parental support for contraceptive use, lack of parental attention, rebellion, normalization of adolescent parenthood in Latino culture, and media. Themes for pregnancy prevention included time alone with physicians, parenting teens as mentors, reproductive health education, and community pregnancy-prevention programs. CONCLUSION: Multiple factors contribute to teen pregnancy in Latino youth, including influences from Latino culture, family, peers, partners, and social determinants of health. Pregnancy prevention should incorporate interventions to address these aspects, including disseminating culturally sensitive education materials, providing parenting teens as peer mentors, encouraging time alone with health care providers, and addressing various social determinants of health.

RESUMO

Sarcopenia is a common complication in patients with liver cirrhosis, which has an adverse effect on the clinical outcome and prognosis. Attention must be paid to early detection and active diagnosis and treatment. Clinically, the diagnosis process of finding suspicious cases can be traced through screening-assessment-diagnosis-severity evaluation. On the ground of treating liver cirrhosis and its complications, reasonable nutritional intervention and exercise are currently important measures for the treatment of liver cirrhosis with sarcopenia, and the role of hormone supplementation and drug therapy for skeletal muscle metabolism needs to be further investigated.

RESUMO

Direct-acting antiviral medications (DAAs) have revolutionized care for hepatitis C positive (HCV+) liver (LT) and kidney (KT) transplant recipients. Scientific Registry of Transplant Recipients registry data were integrated with national pharmaceutical claims (2007-2016) to identify HCV treatments before January 2014 (pre-DAA) and after (post-DAA), stratified by donor (D) and recipient (R) serostatus and payer. Pre-DAA, 18% of HCV+ LT recipients were treated within 3 years and without differences by donor serostatus or payer. Post-DAA, only 6% of D-/R+ recipients, 19.8% of D+/R+ recipients with public insurance, and 11.3% with private insurance were treated within 3 years (P < .0001). LT recipients treated for HCV pre-DAA experienced higher rates of graft loss (adjusted hazard ratio [aHR] 1.34 1.852.10 , P < .0001) and death (aHR 1.47 1.681.91 , P < .0001). Post-DAA, HCV treatment was not associated with death (aHR 0.34 0.671.32 , P = .25) or graft failure (aHR 0.32 0.641.26 , P = .20) in D+R+ LT recipients. Treatment increased in D+R+ KT recipients (5.5% pre-DAA vs 12.9% post-DAA), but did not differ by payer status. DAAs reduced the risk of death after D+/R+ KT by 57% (0.19 0.430.95 , P = .04) and graft loss by 46% (0.27 0.541.07 , P = .08). HCV treatment with DAAs appears to improve HCV+ LT and KT outcomes; however, access to these medications appears limited in both LT and KT recipients.

RESUMO

Objective: Less surveys on the economic burden of hepatitis B (HB)-related diseases have been conducted in China, so the socioeconomic harm caused by the diseases is not clear and the key parameters for economic evaluation of hepatitis B prevention and treatment are lacking. This study aimed to analyze the direct, indirect and intangible expenditures of hospitalized patients with HB-related diseases during hospitalization and during a year in different areas of China. Methods: The hospitals for infectious diseases and the large general hospitals in 12 areas in China were selected in the study. All the inpatients with HB-related diseases were surveyed by cluster sampling of consecutive cases. The direct expenditure included direct medical cost and direct non-medical cost. The indirect expenditure, including work loss of patients and caregivers, were calculated by using human capital method for urban and rural populations in 12 areas. The intangible expenditure were reflected by willing to pay and stochastic tournament. The influencing factors of direct and indirect costs were identified by stepwise linear multi-variation regression analysis. Results: A total of 27 hospitals in 12 areas were included in the survey. A total of 4 718 cases were surveyed, the overall response rate was 77.7%. The average hospital stay was 29.2 days (27-34) and the hospitalization expenditure was averagely 16 832.80 yuan (RMB) per case, in which the highest proportion (61.2%) was medicine fees [10 365.10 yuan (RMB)]. The average direct expenditure and indirect expenditure were consistent with the severity of illness, which were 18 336.10 yuan (RMB) and 4 759.60 yuan (RMB) respectively, with the ratio of 3.85 ∶ 1. The direct medical expenditure [17 434.70 yuan (RMB)] were substantially higher than the direct non-medical expenditure [901.40 yuan (RMB)]. It was found that the hospitalization expenses was highest in direct medical expenditure and the transportation expenses was highest in direct non-medical expenditures. Among the average indirect expenditure, the loss of income for the patients [3 832.50 yuan (RMB)] was higher than that for the caregivers [927.20 yuan (RMB)]. The total direct and indirect expenditure was highest for liver transplantation, followed by severe hepatitis, hepatocellular carcinoma and decompensated cirrhosis, acute hepatitis B, compensated cirrhosis and chronic hepatitis B. The influencing factors for both direct and indirect expenditure were high hospital level, severity of hepatitis B, living in urban area, antiviral therapy, long hospitalization and monthly income of family. For average 3.74 outpatient visits and 1.51 hospitalization, the average annual direct, indirect and intangible expenditure for HB-related diseases were 30 135.30, 6 253.80 and 44 729.90 yuan (RMB) [totally 81 119.00 yuan (RMB)], accounting for 37.3%, 7.7% and 55.0%, respectively. Of the annual direct medical expenditure [28 402.80 yuan (RMB)], which were much higher than non-medical expenditure [1 732.50 yuan (RMB)], hospitalization expenditure [26 074.20 yuan (RMB)] was higher than outpatient visit expenditure [4 061.10 yuan (RMB)]. The annual indirect expenditures for outpatient visit and hospitalization were 763.60 and 5 490.10 yuan (RMB), respectively. Of the annual intangible expenditure, the highest was that for primary hepatocellular carcinoma, followed by cirrhosis, chronic hepatitis B, severe hepatitis B, liver transplantation and acute hepatitis B. Conclusions: A heavy economic burden has been caused by HB-related diseases in China, and patients are more likely to rely on medical service rather than non-medical service. It is necessary to take effective treatment measures to prevent the adverse outcome of HB related diseases and achieve significant economic benefits. The influence of HB related diseases on mental health of the people can be reflected by an economics term, intangible expenditure.

RESUMO

Incompatible living donor kidney transplantation (ILDKT) has been established as an effective option for end-stage renal disease patients with willing but HLA-incompatible living donors, reducing mortality and improving quality of life. Depending on antibody titer, ILDKT can require highly resource-intensive procedures, including intravenous immunoglobulin, plasma exchange, and/or cell-depleting antibody treatment, as well as protocol biopsies and donor-specific antibody testing. This study sought to compare the cost and Medicare reimbursement, exclusive of organ acquisition payment, for ILDKT (n = 926) with varying antibody titers to matched compatible transplants (n = 2762) performed between 2002 and 2011. Data were assembled from a national cohort study of ILDKT and a unique data set linking hospital cost accounting data and Medicare claims. ILDKT was more expensive than matched compatible transplantation, ranging from 20% higher adjusted costs for positive on Luminex assay but negative flow cytometric crossmatch, 26% higher for positive flow cytometric crossmatch but negative cytotoxic crossmatch, and 39% higher for positive cytotoxic crossmatch (p < 0.0001 for all). ILDKT was associated with longer median length of stay (12.9 vs. 7.8 days), higher Medicare payments ($91 330 vs. $63 782 p < 0.0001), and greater outlier payments. In conclusion, ILDKT increases the cost of and payments for kidney transplantation.

RESUMO

Kidney transplantation has become more resource intensive as recipient complexity has increased and average donor quality has diminished over time. A national retrospective cohort study was performed to assess the impact of kidney donor and recipient characteristics on transplant center cost (exclusive of organ acquisition) and Medicare reimbursement. Data from the national transplant registry, University HealthSystem Consortium hospital costs, and Medicare payments for deceased donor (N = 53 862) and living donor (N = 36 715) transplants from 2002 to 2013 were linked and analyzed using multivariate linear regression modeling. Deceased donor kidney transplant costs were correlated with recipient (Expected Post Transplant Survival Score, degree of allosensitization, obesity, cause of renal failure), donor (age, cause of death, donation after cardiac death, terminal creatinine), and transplant (histocompatibility matching) characteristics. Living donor costs rose sharply with higher degrees of allosensitization, and were also associated with obesity, cause of renal failure, recipient work status, and 0-ABDR mismatching. Analysis of Medicare payments for a subsample of 24 809 transplants demonstrated minimal correlation with patient and donor characteristics. In conclusion, the complexity in the landscape of kidney transplantation increases center costs, posing financial disincentives that may reduce organ utilization and limit access for higher-risk populations.

RESUMO

A nationwide survey of hepatitis B virus (HBV)-associated economic burden has not previously been performed in China. The purpose of this study was to examine the direct, indirect, and intangible costs of HBV-related diseases within the span of one year. A random sample was taken from specialty and general hospitals across 12 cities in six provinces of China. Intangible costs were estimated based on willingness to pay or open-ended answers provided by patients. The results showed that 27 hospitals were enrolled, with a sample population of 4726 patients (77.7% response rate). The average annual costs were $4454.0 (direct), $924.3 (indirect), and $6611.10 (intangible), corresponding to 37.3%, 7.7%, and 55.1% of the total costs, respectively. The direct medical fees were substantially greater than the non-medical fees. Annual indirect costs were divided into outpatient ($112.9) and inpatient ($811.40) loss of income. The intangible costs of chronic HBV were notably higher than either the direct or indirect costs, consistent with the social stigma in China. The comparison amongst individual cities for the average ratio of direct to indirect costs revealed that the sizes of ratios were negatively correlated with the socioeconomic status of the regions. This study suggested that as a whole in China, the HBV-related diseases caused a heavy financial burden which was positively associated with disease severity. Although the intangible costs coincided with a high prevalence of discrimination against CHB patients in Chinese society, our study may serve as future reference for detailed exploration.

RESUMO

The infrequent use of ABO-incompatible (ABOi) kidney transplantation in the United States may reflect concern about the costs of necessary preconditioning and posttransplant care. Medicare data for 26 500 live donor kidney transplant recipients (2000 to March 2011), including 271 ABOi and 62 A2-incompatible (A2i) recipients, were analyzed to assess the impact of pretransplant, transplant episode and 3-year posttransplant costs. The marginal costs of ABOi and A2i versus ABO-compatible (ABOc) transplants were quantified by multivariate linear regression including adjustment for recipient, donor and transplant factors. Compared with ABOc transplantation, patient survival (93.2% vs. 88.15%, p = 0.0009) and death-censored graft survival (85.4% vs. 76.1%, p < 0.05) at 3 years were lower after ABOi transplant. The average overall cost of the transplant episode was significantly higher for ABOi ($65 080) compared with A2i ($36 752) and ABOc ($32 039) transplantation (p < 0.001), excluding organ acquisition. ABOi transplant was associated with high adjusted posttransplant spending (marginal costs compared to ABOc - year 1: $25 044; year 2: $10 496; year 3: $7307; p < 0.01). ABOi transplantation provides a clinically effective method to expand access to transplantation. Although more expensive, the modest increases in total spending are easily justified by avoiding long-term dialysis and its associated morbidity and cost.

RESUMO

Although biliary complications (BCs) have a significant impact on the outcome of liver transplantation (LT), variation in BC rates among transplant centers has not been previously analyzed. BC rate, LT outcome and spending were assessed using linked Scientific Registry of Transplant Recipients and Medicare claims (n = 16,286 LTs). Transplant centers were assigned to BC quartiles based upon risk-adjusted observed to expected (O:E) ratio of BC separately for donation after brain death (DBD) and donation after cardiac death (DCD) donors. The median incidence of BC was 300% greater in the highest versus lowest DBD quartiles (19.0% vs. 5.9%) and varied 250% between DCD quartiles (20.3%-8.4%). Donor and recipient characteristics suggest that high BC centers actually used lower donor risk index organs, fewer split livers and fewer imports (p < 0.001 for all). Transplant at a center in the highest O:E quartile was associated with increased posttransplant mortality (adjusted hazard ratio [aHR] 2.53, p = 0.007) in DCD transplant and increased graft loss (aHR 1.21, p = 0.02) in DBD transplant. Medicare spending was $22,895 (p < 0.0001) higher at centers in highest versus lowest BC quartile. In summary, BC rates vary widely among transplant centers and higher rates are a marker for an increased risk of death, graft failure and health-care spending.

RESUMO

OBJECTIVES: The objectives of this study were 2-fold: (1) to examine the association of pharmacy closures with prescription drug use by Medicaid recipients in Iowa; and (2) to evaluate how drug utilization patterns differ between patients whose pharmacies closed and patients whose pharmacies remained open. DESIGN: A 2-group pretest-posttest study of Medicaid enrollees who may have been affected by pharmacy closures. Prescription medication use during the periods preceding and after pharmacy closures was compared. A comparison group was used to account for extraneous factors. PATIENTS AND METHODS: Sixteen community pharmacies were selected from a pool of pharmacies that closed during 1994; 1092 patients were identified as the main users of these pharmacies, and a comparison group of 3491 patients whose main pharmacies had not closed also was identified. The average number of each patient's prescription claims for the 6 months preceding closing and the 6 months after closing was computed. Multiple regression analysis was conducted to determine whether any association existed between pharmacy closures and the use of prescription drugs. RESULTS: Patients whose pharmacies closed during 1994 had fewer prescription claims after the closings than before the closings. In contrast, patients whose pharmacies remained open had more prescription claims. This difference remains statistically significant after controlling for other factors, such as patient demographics and health status. CONCLUSIONS: A decrease in prescription drug use was associated with pharmacy closures. Attention should be directed to patient access to prescription medications in rural areas, as relatively more pharmacies close in rural areas.

RESUMO

Physical assessment method (PAM) and value assessment method (VAM) for ecosystems services assessment were compared, and their strengths and weaknesses were analyzed. The comparison and analysis demonstrated that in some cases, different, even opposite results will be drawn with these two methods for the ecosystems services assessment of one ecosystem. The functions or effects of PAM and VAM are different for different assessment purposes or different spatial scales, but they will promote and complement each other to some extent.

RESUMO

Children who receive radiation for malignant tumors in the orbital area frequently develop widespread craniofacial deformities. These affect the skull, orbit, maxilla, and mandible. When these patients seek treatment at a later age, they require careful assessment using cephalometrics and three-dimensional imaging. It is recommended that the four levels of skeletal deformity be corrected in a single procedure, that is frontotemporal expansion with repositioning of the skull base area, orbital expansion and repositioning together with maxillary and mandibular surgery. Bone grafts should be inlay rather than onlay and soft tissue should be supplied by free-tissue transfer. This counteracts any residual ischemia related to the previous radiation therapy. The second surgical stage is designed to reconstruct the socket and the eyelids to allow more satisfactory rehabilitation with an ocular prosthesis. In patients who have a globe present, the usual enophthalmos can be corrected by repositioning of the eye as part of the first procedure by reducing the anteroposterior dimensions of the socket. In bilateral cases, the deformity is hourglass in nature and requires correction in the frontal and temporal area with lateral displacement of the orbits. A bimaxillary procedure is also indicated. It is emphasized that to formulate a satisfactory operative plan an in-depth three-dimensional analysis of the deformity is mandatory.

RESUMO

We describe a simple, non-invasive and practical method to determine the peak velocity of tricuspid regurgitant flow (and hence derive systolic pulmonary artery pressure) from examination of the dynamics of retrograde tricuspid flow on Doppler. Based on a previously described relationship between right ventricular systolic pressure and the time interval between pulmonary valve closure and tricuspid valve opening, our technique does not require the peak tricuspid regurgitant velocity to be recorded; nor, as in previous studies does it rely upon recording the jugular venous pulse, right ventricular apexcardiogram or invasive pressure measurements. We have studied 65 patients with right ventricular disease (53 with pulmonary hypertension), and 24 with dilated cardiomyopathy, with M-mode, two-dimensional echocardiography, Doppler, and phonocardiography. The peak tricuspid regurgitant velocity could be predicted from the interval between pulmonary closure and the end of the tricuspid regurgitant signal on Doppler in patients with pulmonary hypertension and those with right ventricular disease with normal pulmonary artery pressure, but not in patients with dilated cardiomyopathy. In patients with pulmonary hypertension or right ventricular dilatation, this may be a useful alternative method in estimating pulmonary artery pressure from Doppler, in cases where it is not possible to record the peak tricuspid regurgitant velocity.
