Prevalence and predictors of microalbuminuria in patients with type 2 diabetes mellitus: a cross-sectional observational study in Oman

AIM: To evaluate the prevalence and predictors of microalbuminuria in type 2 diabetics in Oman. METHODS: All patients attending an outpatient diabetic clinic at the Sultan Qaboos University Hospital between 2002 and 2003 were enrolled in the study. RESULTS: A total of 261 patients were included in this study. The mean overall age of the cohort was 50+/-13 years, and 57% were male. The proportion of subjects who had microalbuminuria was 27% (n=70; N=261). The logistic regression model indicated that significant predictors for the development of microalbuminuria include HbA(1c), log creatinine, and the presence of hypertension. A one unit increase in HbA(1c) was associated with a 23% increase in the odds of developing microalbuminuria (OR 1.23; 95% CI: 1.10-1.37; p<0.001). Additionally, patients that had a one unit increase in log creatinine were 5.72 times more likely to develop microalbuminuria (OR 5.72; 95% CI: 1.86-17.59; p=0.002). Furthermore, patients who were hypertensive were 2.37 times more likely to have microalbuminuria (OR 2.37; 95% CI: 1.11-5.09; p=0.026). CONCLUSIONS: The prevalence of microalbuminuria in patients with type 2 diabetes in this study was 27%. Significant predictors of microalbuminuria included HbA(1c), creatinine, and the presence of hypertension.     

Baseline characteristics, management practices, and in-hospital outcomes of patients with acute coronary syndromes: Results of the Saudi project for assessment of coronary events (SPACE) registry

Objectives

The Saudi Project for Assessment of Coronary Events (SPACE) registry is the first in Saudi Arabia to study the clinical features, management, and in-hospital outcomes of acute coronary syndrome (ACS) patients.

Methods

We conducted a prospective registry study in 17 hospitals in Saudi Arabia between December 2005 and December 2007. ACS patients included those with ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction and unstable angina; both were reported collectively as NSTEACS (non-ST elevation acute coronary syndrome).

Results

5055 patients were enrolled with mean age ± SD of 58 ± 12.9 years; 77.4% men, 82.4% Saudi nationals; 41.5% had STEMI, and 5.1% arrived at the hospital by ambulance. History of diabetes mellitus was present in 58.1%, hypertension in 55.3%, hyperlipidemia in 41.1%, and 32.8% were current smokers; all these were more common in NSTEACS patients, except for smoking (all P < 0.0001). In-hospital medications were: aspirin (97.7%), clopidogrel (83.7%), beta-blockers (81.6%), angiotensin converting enzyme inhibitors/angiotensin receptor blockers (75.1%), and statins (93.3%). Median time from symptom onset to hospital arrival for STEMI patients was 150 min (IQR: 223), 17.5% had primary percutaneous coronary intervention (PCI), 69.1% had thrombolytic therapy, and 14.8% received it at less than 30 min of hospital arrival. In-hospital outcomes included recurrent myocardial infarction (1.5%), recurrent ischemia (12.6%), cardiogenic shock (4.3%), stroke (0.9%), major bleeding (1.3%). In-hospital mortality was 3.0%.

Conclusion

ACS patients in Saudi Arabia present at a younger age, have much higher prevalence of diabetes mellitus, less access to ambulance use, delayed treatment by thrombolytic therapy, and less primary PCI compared with patients in the developed countries. This is the first national ACS registry in our country and it demonstrated knowledge-care gaps that require further improvements.     

Disability,depression and somatization in a low back pain population

Objective: The aim of this study was to determine the prevalence of low back pain (LBP) in a primary care setting population and examine its association with the symptoms of depression and somatization. Methods: This is a cross‐sectional study, utilising a survey carried out in primary health care clinics (PHCs) in Al‐Ain, United Arab Emirates (UAE). A multistage stratified sampling design was used and a representative sample of 1304 UAE nationals aged 18–65 years who attended PHC clinics for any reason were included and 1103 (84.5%) subjects agreed to participate and responded to the questionnaire during a period from June 2001 to January 2002. A specially designed questionnaire with three parts was used for the data collection: socio‐demographic information of the studied subjects, modified version of the Roland‐Morris scale for evaluating back‐related functional disability and SCL‐90 R for depression and somatization subscales was used to assess depressive and somatic symptoms. Results: Of the total number of subjects surveyed (1103), 586 (53.1%) were men and 517 (46.9%) women. The mean age was 34.9 ± 13.4 years for men and 33.5 ± 11.8 years for women. The prevalence of LBP in the studied subjects was 64.7% (95% CI, 60.7–68.5] with 46.7% among men and 53.3% among women. There were a significant differences between the subjects with LBP and without LBP with respect to gender (P < 0.001), body mass index (BMI) (P < 0.001), occupational status (P < 0.001) and living environment (P = 0.016). Functional disability was higher in patients with LBP. Young patients in aged 15–34 years, patients with preparatory/secondary educational level and students showed higher depressive symptoms. A similar pattern was found in patients with somatic symptoms. Factor analysis revealed a strong association between depression and somatization in LBP patients. Conclusions: Functional disability was higher in with LBP. Furthermore, symptoms of depression and somatization are prevalent among LBP patients.     

Peri‐implant soft tissue inflammatory parameters and crestal bone loss among waterpipe (narghile) smokers and never‐smokers with and without type 2 diabetes mellitus

1 Background

Peri‐implant soft tissue inflammatory parameters and crestal bone loss (CBL) among waterpipe smokers (WS) with and without type 2 diabetes mellitus (T2DM) remains uninvestigated. The aim of the present study was to assess peri‐implant soft tissue inflammatory parameters and CBL among WS and never smokers (NS) with and without T2DM.

2 Methods

Demographic data and information regarding duration of implants in function, daily frequency of smoking, duration and treatment of T2DM, and daily toothbrushing was collected using a questionnaire. Peri‐implant plaque index (PI), bleeding on probing (BOP), probing depth (PD) ≥4 mm, CBL, and hemoglobin A1c (HbA1c) levels were assessed in all individuals. Level of significance was set at 5%.

3 Results

Seventy‐nine male individuals (39 patients with T2DM [20 WS and 19 NS] and 40 systemically healthy individuals [21 WS smokers and 19 NS]) were included. The mean age was comparable among individuals in all groups. The mean HbA1c levels were significantly higher among patients with T2DM compared to controls (P < 0.01). Peri‐implant PI, BOP, PD, and CBL were comparable among WS and NS with T2DM. Among patients without T2DM, PI (P < 0.05), PD ≥4 mm (P < 0.05) and mesial and distal CBL (P < 0.05) were significantly higher in WS than NS. Among individuals without T2DM, BOP was significantly higher among NS (P < 0.05) than WS. In patients with T2DM, BOP was comparable among WS and NS.

4 Conclusions

Peri‐implant soft tissue inflammatory parameters and CBL were comparable among WS and NS with T2DM. Among individuals without T2DM, these parameters were worse among WS than NS.     

Detection of refrigerator-associated 60 Hz alternating current as ventricular fibrillation by an implantable defibrillator.

This report describes a patient with an implantable defibrillator who suffered an inappropriate defibrillation shock upon retrieving some food items from his inadequately earthed refrigerator. Noise typical of electrical interference can be observed in the stored electrogram of the episode. The patient was instructed to earth his home appliances, but he decided to avoid his refrigerator altogether, and has had no subsequent shocks.     

Revisiting human IL-12Rβ1 deficiency: a survey of 141 patients from 30 countries

Interleukin-12 receptor β1 (IL-12Rβ1) deficiency is the most common form of Mendelian susceptibility to mycobacterial disease (MSMD). We undertook an international survey of 141 patients from 102 kindreds in 30 countries. Among 102 probands, the first infection occurred at a mean age of 2.4 years. In 78 patients, this infection was caused by Bacille Calmette-Guérin (BCG; n = 65), environmental mycobacteria (EM; also known as atypical or nontuberculous mycobacteria) (n = 9) or Mycobacterium tuberculosis (n = 4). Twenty-two of the remaining 24 probands initially presented with nontyphoidal, extraintestinal salmonellosis. Twenty of the 29 genetically affected sibs displayed clinical signs (69%); however 8 remained asymptomatic (27%). Nine nongenotyped sibs with symptoms died. Recurrent BCG infection was diagnosed in 15 cases, recurrent EM in 3 cases, recurrent salmonellosis in 22 patients. Ninety of the 132 symptomatic patients had infections with a single microorganism. Multiple infections were diagnosed in 40 cases, with combined mycobacteriosis and salmonellosis in 36 individuals. BCG disease strongly protected against subsequent EM disease (p = 0.00008). Various other infectious diseases occurred, albeit each rarely, yet candidiasis was reported in 33 of the patients (23%). Ninety-nine patients (70%) survived, with a mean age at last follow-up visit of 12.7 years ± 9.8 years (range, 0.5-46.4 yr). IL-12Rβ1 deficiency is characterized by childhood-onset mycobacteriosis and salmonellosis, rare recurrences of mycobacterial disease, and more frequent recurrence of salmonellosis. The condition has higher clinical penetrance, broader susceptibility to infections, and less favorable outcome than previously thought.

Management of high-grade squamous intraepithelial lesion patients with positive margin after LEEP conization: A retrospective study

To explore the optimal way to manage patients with high-grade squamous intraepithelial lesion (HSIL) and positive margin by identifying the risk factors for its recurrence and residue.A retrospective study was conducted on 267 cases of a pathologically confirmed HSIL with positive margin following conization by loop electrosurgical excisional procedure (LEEP) between January 2010 and December 2015. One hundred two cases were selected for regular follow-up every 6 months, and 165 cases were selected for a second surgery (repeat cervical conization or hysterectomy) within 3 months of initial LEEP. We analyzed the association between recurrent or residual diseases and these factors: age, menopausal status, ThinPrep cytologic test (TCT) results, high-risk human papillomavirus (HR-HPV) infection, pathological grades of the margin, number of involved margins, and glandular involvement.The recurrence rate among 102 cases who underwent follow-up was 17.6% (18/102). The factors: atypical squamous cells of undetermined significance cannot exclude HSIL (ASC-H) or higher lesions in the pre-LEEP TCT (P = .038), persistent HR-HPV infection at the 6th month post-LEEP (P = .03), HSIL-positive margin (P = .003), and multifocal-involved margin (P = .002) were significantly associated with recurrent disease, while age, menopause, and pre-LEEP HR-HPV infection were not associated with recurrent disease (P > .05). The residual rate among 165 patients who underwent a second surgery was 45.5% (75/165), of which 15 cases were residual cervical cancer. The factors: menopause (P = .02), ≥ASC-H in pre-LEEP TCT (P = .04), pre-LEEP HR-HPV infection (P = .04), ≥HSIL-positive margin (P < .001), and multifocal-involved margin (P < .001) significantly increased the risk of residual disease. No correlation existed between residual disease and age or glandular involvement (P > .05).For patients with a positive margin after LEEP, regular follow-up or second surgery should be selected according to fertility requirement and pathological characteristics of the positive margin, as well as TCT and HR-HPV infection condition.
