To examine the association of individual income and end of life (EOL) care in older cancer decedents in Taiwan.
Retrospective cohort study.
National Health Insurance Research Database (NHIRD) in ...Taiwan.
28,978 decedents >65 years were diagnosed with cancer and died during 2009-2011 in Taiwan. Of these decedents, 10941, 16535, and 1502 were categorized by individual income as having low, moderate, and high SES, respectively.
Indicators of aggressiveness of EOL care: chemotherapy use before EOL, more than one emergency department (ER) visit, more than one hospital admission, hospital length of stay >14 days, intensive care unit (ICU) admission, and dying in a hospital.
Low individual income was associated with more aggressive EOL treatment (estimate -0.30 for moderate income, -0.27 for high income, both p<0.01). The major source of aggressiveness was the tendency for older decedents with low income to die in the acute care hospital. The indicators had an increasing trend from 2009 to 2011, except for hospital stay >14 days.
Low individual income is associated with more aggressive EOL treatment in older cancer decedents. Public health providers should make available appropriate education and hospice resources to these decedents and their families, to reduce the amount of aggressive terminal care such decedents receive.

In this study, the long-term efficacy of hepatitis B virus (HBV) vaccination was assessed using seroprevalence and an age-period-cohort (APC) model of HBV seromarkers among university entrants 30 ...years after the introduction of the national neonatal HBV vaccination program in Taiwan.
In total, data of 17,611 university entrants who underwent university entrance health examinations between 2005 and 2016 were included. The seroprevalence of the HBV surface antigen (HBsAg) and the levels of the antibody against the HBV surface antigen (anti-HBs) in each year group and sex were calculated. The levels of the antibody against the HBV core antigen were examined only for 2012 and 2016. The APC model was used to analyze the HBV carrier rates.
The chronic HBV infection (HBsAg positivity) rate decreased from 9.7% in university students born before June 1974 to <1.0% in students born after 1992. The prevalence of anti-HBs positivity declined, particularly between the 1984-1988 cohort (78.2%-53.2%) and the 1990-1994 cohort (60.6%-44.4%). Our APC model revealed that the chronic HBV carrier rate among the student population was affected significantly by age, period, and cohort (
< 0.001).
HBV vaccination is one of the most effective strategies for preventing HBV infection. However, for complete eradication of HBV infection, the development of strategies that detect vaccination failure more effectively than current strategies do and early implementation of appropriate treatments are both necessary.
Repetitive hypoxic preconditioning (RHP) may provide more efficient protection than single hypoxic preconditioning against renal ischemia/reperfusion-induced injury via hypoxia-induced factor 1α ...(HIF-1α)-dependent heat shock protein 70 (HSP70) pathways.
Wistar rats were subjected to intermittent hypoxic exposure (15
h/day), whereas controls were kept at sea level. We evaluated renal expression of HIF-1α, HSP70, the endoplasmic reticulum stress protein GRP78, caspase 12, Beclin-1, and poly-(ADP-ribose)-polymerase (PARP) with western blotting. Renal apoptosis determined by terminal transferase dUTP nick end labeling (TUNEL), Beclin-1-dependent autophagy, and monocyte/macrophage (ED-1) infiltration were evaluated by immunocytochemistry. Renal function was determined with blood urea nitrogen (BUN) and plasma creatinine levels. HIF-1α inhibitors and Deoxyribonucleotide (DNA) or Ribonucleotide (RNA) interference of HSP70 were used to evaluate their possible roles in this process.
Renal HIF-1α and HSP70 expression were enhanced by hypoxic preconditioning and inhibited by the HIF-1α inhibitor, YC-1, as well as phosphatidylinositol 3-kinase (PI3K)/Akt inhibitors. After the return to normoxia, renal HSP70 protein levels were maintained for one week in the RHP group, but they decayed after one day in the single hypoxic preconditioning group. Ischemia/reperfusion significantly increased renal TUNEL-apoptosis, Beclin-1-dependent autophagy, ED-1 infiltration, expression of GRP78, caspase 12, Beclin-1, PARP, and BUN and plasma creatinine levels in control rats. RHP significantly decreased all ischemia/reperfusion-enhanced parameters. Intraperitoneal pretreatment with YC-1 and quercetin (an inhibitor of HSP70 induction) eliminated RHP-induced protection. Anti-sense oligodeoxyribonucleotides or interference RNA targeting HSP70 abrogated the protection against hypoxia/reoxygenation-induced oxidative injury in RHP-treated proximal tubules.
We demonstrate that RHP promotes HIF-1α-dependent HSP70 signaling to reduce renal ischemia/reperfusion injury.
Lynch syndrome, caused by germline mutations in mismatch repair genes, is a predisposing factor for colorectal cancer (CRC). This retrospective cohort study investigated the risk factors associated ...with the development of CRC in patients with MLH1 and MSH2 germline mutations.
In total, 301 MLH1 and MSH2 germline mutation carriers were identified from the Amsterdam criteria family registry provided by the Taiwan Hereditary Nonpolyposis Colorectal Cancer Consortium. A Cox proportional hazard model was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) to determine the association between the risk factors and CRC development. A robust sandwich covariance estimation model was used to evaluate family dependence.
Among the total cohort, subjects of the Hakka ethnicity exhibited an increased CRC risk (HR = 1.62, 95% CI = 1.09-2.34); however, those who performed regular physical activity exhibited a decreased CRC risk (HR = 0.62, 95% CI = 0.41-0.88). The CRC risk was enhanced in MLH1 germline mutation carriers, with corresponding HRs of 1.72 (95% CI = 1.16-2.55) and 0.54 (95% CI = 0.34-0.83) among subjects of the Hakka ethnicity and those who performed regular physical activity, respectively. In addition, the total cohort with a manual occupation had a 1.56 times higher CRC risk (95% CI = 1.07-2.27) than did that with a skilled occupation. Moreover, MSH2 germline mutation carriers with blood group type B exhibited an increased risk of CRC development (HR = 2.64, 95% CI = 1.06-6.58) compared with those with blood group type O.
The present study revealed that Hakka ethnicity, manual occupation, and blood group type B were associated with an increased CRC risk, whereas regular physical activity was associated with a decreased CRC risk in MLH1 and MSH2 germline mutation carriers.

College of American Pathologists recommended that at least 12 lymph nodes should be harvested for adequate staging of colorectal carcinoma. Lymph node harvesting is routinely performed by a manual ...technique of inspection and palpation, which is laborious and time-consuming. The study assessed the influence of the improved fat-clearing technique on the number of lymph nodes retrieved from colorectal cancer specimens and the clinical efficacy. Seventy colorectal cancer resection specimens were examined and assessed by 4 pathology residents. Thirty-five specimens were handled with the conventional manual technique by inspection and palpation, and the other 35 specimens with the improved fat-clearing technique to retrieve lymph nodes. As a result, compared with the conventional manual technique, the numbers of lymph nodes retrieved with the improved fat-clearing technique were significantly increased from 14.7 ± 6.2 lymph nodes to 20.8 ± 9.0 lymph nodes per specimen (P < .05). Besides, the percentage of cases with at least 12 lymph nodes retrieved increased from 80% to 91%. The result of this study pointed out that using the improved fat-clearing technique to process colorectal specimens could increase the lymph node yield effectively, and was effective, practical, and suitable for routine gross examination.
•XRCC2 rs2040639 is associated with advanced oral squamous cell carcinoma survival.•The A-allele of XRCC2 rs2040639 exhibited a decreased risk for recurrence.•Carrying A-alleles of XRCC2 rs2040639 ...and PRKDC rs7003908 decreased recurrence risk.
To investigate the association between the variants of DNA double-strand break repair genes and the clinical outcomes of patients with oral squamous cell carcinoma (OSCC) undergoing concurrent chemoradiotherapy.
Five variants of DNA double-strand break repair genes in samples from 319 patients with OSCC were genotyped using the Sequenom iPLEX MassARRAY system. Kaplan–Meier curves and Cox proportional hazards analysis were used to identify the factors associated with patient survival.
The XRCC2 rs2040639 (G3063A) polymorphism in the codominant model was associated with decreased recurrence risk (hazard ratio HR = 0.55, 95% confidence interval CI = 0.31–0.98; p = 0.042). A marginally significant interaction was observed between XRCC2 rs2040639 and PRKDC rs7003908 in patients carrying the AA and AA genotypes; these patients showed reduced recurrence risk (HR = 0.36, 95% CI = 0.17–0.79; p = 0.010).
The A-allele of XRCC2 rs2040639 is a favorable prognostic factor for disease-free survival. Patients with these genotypes may benefit from concurrent chemoradiotherapy. Additional confirmation from studies with larger samples or other ethnic populations is warranted.
The association between Sjögren's syndrome (SS) and chronic hepatitis virus infection is inconclusive. Hepatitis B (HBV) and hepatitis C virus (HCV) infections are highly prevalent in Taiwan. We used ...a population-based case-control study to evaluate the associations between SS and HBV and HCV infections.
We identified 9,629 SS patients without other concomitant autoimmune diseases and 38,516 sex- and age-matched controls without SS from the Taiwan National Health Insurance claims data between 2000 and 2011. We utilized multivariate logistic regression to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the associations between SS and HBV and HCV infections. Sex- and age-specific (<55 and ≥55 years) risks of SS were evaluated.
The risk of SS was higher in patients with HCV than in those without chronic viral hepatitis (OR = 2.49, 95% CI = 2.16-2.86). Conversely, HBV infection was not associated with SS (OR = 1.10, 95% CI = 0.98-1.24). Younger HCV patients were at a higher risk for SS (<55 years: OR = 3.37, 95% CI = 2.62-4.35; ≥55 years: OR = 2.20, 95% CI = 1.84-2.62). Men with HCV were at a greater risk for SS (women: OR = 2.26, 95% CI = 1.94-2.63; men: OR = 4.22, 95% CI = 2.90-6.16). Only men with chronic HBV exhibited a higher risk of SS (OR = 1.61, 95% CI = 1.21-2.14).
HCV infection was associated with SS; however, HBV only associated with SS in men.

Background and Aims
Regorafenib has demonstrated its survival benefit for unresectable hepatocellular carcinoma (uHCC) patients in a phase III clinical trial. We aimed to assess the efficacy and ...tolerability of regorafenib and the predictors of treatment outcomes in Taiwanese patients.
Methods
We analyzed the survival, best overall response, predictors of treatment outcomes, and safety for uHCC patients who had tumor progression on sorafenib therapy and received regorafenib as salvage therapy between March 2018 and November 2020.
Results
Eighty‐six patients with uHCC were enrolled (median age, 66.5 years; 76.7% male). The median regorafenib treatment duration was 4.0 months (95% confidence interval CI, 3.6–4.6). The most frequently reported adverse events were hand‐foot skin reaction (44.2%), diarrhea (36.0%), and fatigue (29.1%). No unpredictable toxicity was observed during treatment. The median overall survival (OS) with regorafenib was 12.4 months (95% CI, 7.8–17.0) and the median progression‐free survival (PFS) was 4.2 months (95% CI, 3.7–4.7). Of 82 patients with regorafenib responses assessable, 4 patients (4.9%) achieved a partial response, and 33 (40.2%) had stable disease, leading to a disease control rate (DCR) of 45.1% (n = 37). Patients possessing baseline AFP < 400 ng/ml exhibited a markedly longer median OS, median PFS, and higher DCR compared with their counterparts (15.7 vs. 8.1 months, 4.6 vs. 3.7 months, 60.9% vs. 27.5%, respectively). Despite possessing high baseline AFP levels, patients with early AFP response (>10% reduction at 4 weeks or >20% reduction at 8 weeks after regorafenib administration) exhibited comparable treatment outcomes to those with baseline AFP < 400 ng/ml.
Conclusions
The results of this real‐world study verified the tolerability and efficacy of regorafenib treatment for uHCC patients who failed prior sorafenib therapy, especially for those with lower baseline AFP levels or with early AFP response.
This real‐world study verified the safety and efficacy of regorafenib for Taiwanese patients with unresectable HCC. Patients with lower baseline AFP levels or with early AFP response exhibited a markedly better survival outcome and higher disease control rate.
Objectives: We compared serum levels of chemokines between male elders with major depressive disorder (MDD) and healthy controls, verifying whether any difference exists in the levels of these ...mediators between those with and without current suicidal ideation (SI).
Methods: We enrolled 145 male elders aged 65 or older and analyzed 40 chemokines in patients with MDD with SI (n = 24) and without SI (n = 23), as well as healthy controls (n = 98).
Results: The patients with MDD with SI presented higher levels of MCP-2/CCL8 (p < 0.001) compared with the patients with MDD without SI and the healthy controls.
Conclusions: Current findings suggest a potential role of MCP-2/CCL8 in suicidality among elderly males with depression.
Background The association between chronic hepatitis C virus (HCV) infection and end-stage renal disease (ESRD) has been widely debated. Study Design National population-based cohort study. Setting & ...Participants Insurance claims data from the Taiwan National Health Insurance Research Database in 2000-2005. Predictor Chronic HCV infection as defined by the International Classification of Diseases, Ninth Revision, Clinical Modification. Outcomes ESRD as defined by the International Classification of Diseases, Ninth Revision, Clinical Modification. Results We identified 6,291 adults with chronic HCV infection. The control group included 31,455 sex- and age-matched individuals without evidence of chronic hepatitis. The incidence of ESRD was 2.14-fold higher in patients with chronic HCV infection (HR, 1.53; 95% CI, 1.17-2.01; P = 0.002) than in patients without HCV infection. Age stratification analysis showed that patients aged 50-59 years with chronic HCV infection (HR, 7.77; 95% CI, 4.23-14.3; P < 0.001) had the highest risk of developing ESRD relative to patients aged 20-49 years without chronic HCV infection (interaction P < 0.001). Limitations Lack of clinical data. Conclusions Patients with chronic HCV infection are at greater risk of developing ESRD than individuals without chronic HCV infection. In addition, the risk of developing ESRD is highest in younger patients with HCV infection. Early renal screening programs should be initiated for this high-risk group of young individuals with chronic HCV infection.
