This study aimed to determine trends in prevalence, awareness, and control of hypertension in Malaysia and to assess the relationship between socioeconomic determinants and prevalence of hypertension in Malaysia. The distribution of hypertension in Malaysia was assessed based on available data in 3 National Health and Morbidity Surveys (NHMSs) and 1 large scale non-NHMS during the period of 1996 to 2011. Summary statistics was used to characterize the included surveys. ⋯ A change in the control of hypertension was 13% higher in women than in men. The findings suggest that the magnitude of hypertension in Malaysia needs additional attention. Strengthening the screening for hypertension in primary health-care settings in the high-risk groups and frequent health promotion to the community to enhance individual awareness and commitment to healthy living would be of immense value.

We used American Joint Committee on Cancer (AJCC) Staging Manual system to assess the prognostic significance of tumor regression grading (TRG) for locally advanced rectal cancer (LARC) (T3/4 or N+) patients who were treated with preoperative chemoradiotherapy (CRT). The 4 AJCC-TRG classifications were evaluated on surgical specimens from 295 LARC patients receiving CRT. Overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were estimated using Kaplan-Meier method and Cox regression model. ⋯ By multivariate analysis, AJCC-TRG (P = 0.033), residual lymph node metastasis (ypN+) (P < 0.001) and pretreatment CA19-9 level (P = 0.035) were significant predictors of OS. Pathological T category (P = 0.006) and nodal status (P < 0.001) after CRT were the most important independent prognostic factors for DFS. AJCC-TRG is a prognostic factor for LARC patients receiving CRT, independent of pathological staging.

Case Reports
First Case Report of Smith-Magenis Syndrome (SMS) Among the Arab Community in Nazareth: View and Overview.
Smith-Magenis syndrome (SMS0) is a complex and rare genetic multisystem disorder characterized by a variable pattern of cognitive deficits accompanied by a1 distinctive behavioral phenotype. SMS is characterized by subtle facial dysmorphology, short stature, sleep disturbances, and neurobehavioral abnormalities. Little is known about the manifestation of his unique case among Arab population and its strategic treatment. ⋯ Sleep and behavioral disturbances treatment include a combination of the daytime dose of acebutolol with an evening oral dose of melatonin. Melatonin as chronobiotic, antioxidant, and analgesic agent showed to be effective in different primary sleep disorders and in those associated with neurobehavioral disorders. Based on the beneficial effect of melatonin, it will be useful to use serum levels of melatonin as a follow-up test.

To determine the prevalence of antineutrophil cytoplasmic antibodies (ANCA) in patients with infective endocarditis (IE) in internal medicine; and to compare clinical and biochemical features and outcome between patients exhibiting IE with and without ANCA. Fifty consecutive patients with IE underwent ANCA testing. The medical records of these patients were reviewed. ⋯ Our study identifies a high prevalence of ANCA in unselected patients with IE in internal medicine (24%). Our findings further underscore that ANCA may be associated with a subacute form of IE leading to multiple valve involvement and more frequent renal impairment. Because death was due to IE complications in all patients, our data suggest that aggressive therapy may be required to improve such patients' outcome.

Observational Study
Risks of Adverse Events Following Coprescription of Statins and Calcium Channel Blockers: A Nationwide Population-Based Study.
Some statins (simvastatin, lovastatin, and atorvastatin) are metabolized by cytochrome P450s 3A4 (CYP3A4). Inhibitors of CYP3A4 including some calcium channel blockers (CCBs) might increase statin blood concentration, owing to drug-drug interactions. Risk of adverse events such as acute kidney injury might occur following the coprescription of CYP3A4-metabolized statins and CCBs that inhibit CYP3A4. ⋯ Patients who received CYP3A4-metabolized statins had significantly higher risk of acute kidney injury (adjusted odds ratio [OR] = 2.12; 95% CI = 1.35-3.35), hyperkalemia (adjusted OR = 2.94; 95% CI = 1.36-6.35), acute myocardial infarction (adjusted OR = 1.55; 95% CI = 1.16-2.07), and acute ischemic stroke (adjusted OR = 1.35; 95% CI = 1.08-1.68) than those who received non-CYP3A4-metabolized statins. This nationwide cohort study demonstrated the increased risk of adverse events following the coprescription of CYP3A4-metabolized statins and CCBs that inhibit CYP3A4. Therefore, it is important to take into account the potential adverse events while coprescribing CYP3A4-metabolized statins and CCBs that inhibit CYP3A4.
