Ni-Catalyzed Regioselective Hydroarylation involving 1-Aryl-1,3-Butadienes along with Aryl Halides.
37 and 0.22 mmHg, respectively, in the morning and by 0.45 and 0.30 mmHg, respectively, in the evening (all P-values less then 0.001). The magnitude of associations was stronger for indoor than outdoor temperature. Similarly, a 1 °C increase in indoor temperature above outdoor temperature decreased systolic and diastolic BP by 0.33 and 0.12 mmHg, respectively, in the morning and by 0.45 and 0.26 mmHg, respectively, in the evening independent of outdoor temperature (all P-values less then 0.001). In conclusion, controlling indoor temperature is important to stabilize home BP levels.Hypertension has remained the number one cause of cardiovascular death in the Philippines for over three (3) decades. Despite this finding, the burden accounted for by hypertension is investigated to a lesser extent. We performed this study to determine the socioeconomic impact of hypertension in the Philippines, and it was projected in the next 30 years. We gathered primary data through interviews, Labor Force Survey (N = 806), and secondary data from various government published reports. The cost of illness (COI) was calculated using the direct morbidity and mortality costs. The impact (% of respondents) of uncontrolled hypertension on productivity at work showed the following; four (4) days missing work (72%) and ten (10) days lost of productivity (63%). The impact (% of respondents) of uncontrolled hypertension on productivity at home showed the following six (6) days of household suspended (66%), eleven (11) days reduced household work (78%), and five (5) days affected social activity (60%). The productivity loss of premature mortality accounts for 17% of the total economic burden in 2020 and will increase to 20% by 2050. In 2020, 70% of the total economic burden was accounted for direct & indirect care. At its present value, the economic cost of hypertension is expected to increase from US$1 billion in 2020 to US$1.9 billion by 2050. The socioeconomic impact of uncontrolled hypertension in the Philippines was enormous, challenging, and overwhelming for the next 30 years.We measured dietary salt intake in 26 patients with primary aldosteronism treated with mineralocorticoid receptor antagonists and evaluated whether plasma renin levels were affected by dietary salt intake pre-treatment and post 6 months of mineralocorticoid receptor antagonist treatment. The dietary salt intake level was calculated using spot urine sodium and creatinine concentrations, body weight, height, and age. Vacuolin-1 The clinical parameters pre- and post- treatment were compared. The systolic and diastolic blood pressure levels decreased, and the serum potassium and active renin concentration increased significantly. Although the dietary salt intake did not change after treatment, the differences in dietary salt intake and active renin concentration pre- and post- treatment were inversely correlated (r = -0.418, p = 0.03). The 26 patients were divided into two groups with active renin concentration levels ≥5 pg/mL (Group 1) and less then 5 pg/mL (Group 2) after treatment. The Group parameters did not differ pre- and post- treatment. Group 1 evidenced improvements in systolic and diastolic blood pressures, and the potassium level and active renin concentration over time; Group 2 did not. Group 1 evidenced no significant correlation between the differences in dietary salt intake and active renin concentration levels (r = -0.481, p = 0.11) but Group 2 showed a strong inverse correlation (r = -0.7599, p = 0.01). In conclusion, we found that an active renin concentration level less then 5 pg/mL post-mineralocorticoid receptor antagonist treatment may indicate that salt sensitivity has not adequately improved, emphasizing the importance of measuring plasma renin levels after such treatment.We conducted a one-year follow-up study to determine the temporal change in exercise habits and the related factors during the COVID-19 pandemic in older hypertensive patients. A total of 190 patients were 76.1 ± 5.7 years, and 44.7% (n = 85) were male. One-hundred fifty-one and 138 patients had exercise habits at baseline and a year later, respectively (p = 0.053). We categorized patients based on the change in exercise habits (at baseline/a year later) Group A +/+ (n = 122); Group B +/- (n = 29); Group C -/+ (n = 16); and Group D -/- (n = 23). In women, the geriatric depression scale and the incidence of falls in a year were higher in group B (n = 18) than (n = 61) in group A. Such a trend was not observed in men. In conclusion, although exercise habit in older hypertensive patients was well-maintained in our survey, reduced physical activity was associated with depression and risk of fall only in women.With the promising cardiovascular benefits in the STEP and SPRINT trials, the 2022 Taiwan's hypertension guidelines redefined the hypertension threshold as 130/80 mmHg and a universal blood-pressure target of less then 130/80 mmHg. This study's objective was to examine the cost-effectiveness of the intensive blood-pressure target for hypertensive patients using estimated lifetime medical costs and quality-adjusted life years (QALY) from the Taiwan national payer's perspective. We developed a lifetime Markov model comparing the intensive and conservative blood-pressure targets. Incremental cost-effectiveness ratio (ICER) against the willing-to-pay thresholds at the one-time [US$34,000(NT$1,020,000)] and three-time [US$100,000(NT$3,000,000)] gross domestic product per capita were defined as very cost-effect and only cost-effective. The cost-effectiveness in different age stratifications and cardiovascular risks treated with a more intensive target (120 mmHg) were examined in the subgroup analyses. The new blood-pressure treatment target produced more lifetime medical costs [US$31,589(NT$947,670) versus US$26,788(NT$803,640)] and QALYs (12.54 versus 12.25), and the ICER was US$16,589(NT$497,670), which was 99.1% and 100% probability of a very cost-effective and cost-effective strategy. The ICERs in all age stratifications had more than a 90% probability of being very cost-effective, and ICERs decreased with age. More intensive control in patients with high cardiovascular risks produced a lower ICER [US$14,547(NT$436,410)]. In conclusion, Taiwan's new blood-pressure treatment target can prevent more cardiovascular events with acceptable costs per QALY below the willing-to-pay thresholds. The cost-effectiveness of intensive control is consistent across different ages and more pronounced with the increase in age and cardiovascular risk.This study investigated the mechanism underlying the beneficial effects of mineralocorticoid receptor (MR) antagonists in patients with resistant hypertension and diabetic nephropathy by examining post-translational modification of the MR by O-linked-N-acetylglucosamine (O-GlcNAc), which is strongly associated with type 2 diabetes. Coimmunoprecipitation assays in HEK293T cells showed that MR is a target of O-GlcNAc modification (O-GlcNAcylation). The expression levels and transcriptional activities of the receptor increased in parallel with its O-GlcNAcylation under high-glucose conditions. Liquid chromatography-tandem mass spectrometry revealed O-GlcNAcylation of the MR at amino acids 295-307. Point mutations in those residues decreased O-GlcNAcylation, and both the protein levels and transcriptional activities of MR. In db/db mouse kidneys, MR protein levels increased in parallel with overall O-GlcNAc levels of the tissue, accompanied by increased SGK1 mRNA levels. The administration of 6-diazo-5-oxo-L-norleucin, an inhibitor of O-GlcNAcylation, reduced tissue O-GlcNAc levels and MR protein levels in db/db mice. Thus, our study showed that O-GlcNAcylation of the MR directly increases protein levels and transcriptional activities of the receptor under high-glucose conditions in vitro and in vivo. These findings provide a novel mechanism of MR as a target for prevention of complications associated with diabetes mellitus.Excessive dietary salt consumption is one of the most important risk factors for hypertension. Metabolic disorders often coexist with hypertension, and excess salt intake has been reported to underlie metabolic disorders, such as insulin resistance. Therefore, we tested the hypothesis that excessive dietary salt causes metabolic syndrome in the general population. In total, 13886 subjects who participated in our medical checkup were enrolled, and salt intake was assessed using a spot urine sample. The characteristics of participants with metabolic syndrome (n = 1630) were examined at baseline, and then participants without metabolic syndrome (n = 12256) were followed up with the endpoint being the development of metabolic syndrome. The average estimated salt intake in our participants was 8.72 ± 1.93 g/day. A significant association between salt intake and metabolic syndrome was obtained from the logistic regression analysis, and salt intake increased as the number of metabolic disorders in an individual increased at baseline (P  less then  0.001). During the median follow-up period of 52 months, 1669 participants developed metabolic syndrome. Kaplan-Meier analysis demonstrated an increased risk of metabolic syndrome across quartiles of baseline salt intake (log-rank, P  less then  0.001). In the Cox proportional hazard regression analysis where salt intake was taken as a continuous variable, salt intake at baseline was an independent predictor of developing metabolic syndrome. These results suggest that excessive salt intake is significantly associated with the development of metabolic syndrome in the general population. Salt may play an important role in the development of metabolic disorders and hypertension.The prevalence of nonalcoholic fatty liver disease (NAFLD) has been increasing rapidly worldwide, affecting 25-30% of the population. Fatty liver index (FLI) is a validated marker of NAFLD and can be used as a screening tool for hepatic steatosis. The purpose of the study was to evaluate the relationship between FLI and the risk of major cardiovascular events in never treated hypertensive patients. We included 903 hypertensive patients without a history of cardiovascular disease (mean age 52.7 ± 11.4 years; men 55%; baseline clinic BP 149.8 ± 15.2/95.5 ± 10.1 mmHg). Participants were prospectively evaluated for a mean follow-up period of 5.2 ± 3.2 years with at least one annual visit. Patients were also categorized into two groups using an FLI of 60 units. The incidence of cardiovascular events during follow-up was 8.5% (n = 77). Patients with FLI  less then  60 (n = 625) had a better BP control compared to their counterparts with FLI ≥ 60 (n = 278) during follow up (43% vs 33%, p = 0.02). Cox-regression analysis indicated that FLI (Hazard Ratio [HR], 1.05; 95% Confidence Interval [CI], 1.03-1.07, p  less then  0.001), FLI z-scores (HR, 3.66; 95% CI, 2.22-6.04) and high-risk FLI (HR, 7.5; 95% CI, 3.12-18.04) were independent determinants of the outcome after adjustment for baseline and follow-up variables. Stratification by diabetes mellitus indicated that FLI predicted the outcome to a greater extent in those with than those without diabetes (P-interaction less then 0.001). In conclusion, FLI has an independent prognostic value for the incidence of cardiovascular events in newly diagnosed, never-treated hypertensive patients. Therefore, FLI might identify higher-risk patients in the primary prevention of hypertension.
