This study was aimed at evaluating the knowledge and behavior toward venous thromboembolism (VTE) prophylaxis among medical interns. Methods. This is a questionnaire-based cross-sectional observational cohort study of medical interns that used a validated questionnaire. The questionnaire comprised of items that assessed behavior, knowledge, and self-assessment of VTE risk factors, diagnosis, and prophylaxis. The study was conducted in Riyadh, Saudi Arabia, from October 2020 till September 2021. Results. The respondents were 246 medical interns. The overall rate of correct responses to behavior items was 41.82%. The overall rate of correct responses to knowledge items was 47.35%. A total of 61.8% responded negatively to the use of VTE risk assessment guidelines ( p < 0.0001 ). For the self-assessment of knowledge of VTE, more than 70% believed they did not have appropriate knowledge, were not prepared to establish the risk of VTE, and were not prepared to provide adequa...

Methods: SCID-CV was used to establish DSM-IV diagnosis. Sensitivity, specificity, positive and negative predictive values were used to assess test performance and Cohen's Kappa to measure agreement with DSM diagnosis. Results: Twenty-five of 88 participants had a DSM-IV depressive diagnosis. There was considerable non-overlap between 'caseness' on the BDI and HADS (Kappa = 0.44). The HADS depression subscale had poor sensitivity (52%) and poor agreement with clinical diagnosis (Kappa = 0.35). The full BDI had a sensitivity of 88% and a Kappa of 0.54 against a sensitivity of 84% and Kappa of 0.42 for the short form. The HADS anxiety subscale predicted depression as well as the depression subscale (sensitivity 88%, Kappa 0.47). Conclusions: Neither the BDI nor the HADS agrees well with the clinical diagnosis of depressive disorder, nor do they agree well with one another. The anxiety subscale of the HADS appears to measure depression at least as well as the depressive subscale.

Methods and results We conducted a retrospective analysis of 758 STEMI patients (from January 2003 to December 2005), with STEMI onset ,12 h and hs-C-reactive protein determination on admission. Patients were classified into four groups [I (hs-C-reactive protein , 0.48 mg/dL), II (hs-C-reactive protein ! 0.48 to ,1.2 mg/dL), III (hs-C-reactive protein ! 1.2 to ,3.1 mg/dL), IV (hs-C-reactive protein ! 3.1 mg/dL)] according to quartiles of hs-C-reactive protein serum level. The IV quartile hs-C-reactive protein group had a higher incidence of in-hospital mortality and cumulative adverse events. At a mean follow-up of 724 + 376 days (range 0-1393), the IV quartile hs-C-reactive protein group showed lower estimated survival, lower estimated myocardial infarction-free survival and lower estimated event-free survival. At multivariable analysis hs-C-reactive protein appeared to be an independent predictor of long-term mortality (HR: 1.04, 95% CI: 1.01-1.07, P ¼ 0.003), long-term mortality and re-infarction (HR: 1.03, 95% CI: 1.01-1.06, P ¼ 0.008) and adverse events (HR: 1.03, 95% CI: 1.01-1.05, P ¼ 0.03). Conclusion Evaluation of hs-C-reactive protein on admission in STEMI patients undergoing primary PCI allows reliable risk stratification of these patients.

Saudi journal of kidney diseases and transplantation : an official publication of the Saudi Center for Organ Transplantation, Saudi Arabia, 2011

ST segment elevation of more than 1 mm from the baseline is an electrocardiographic presentation ... more ST segment elevation of more than 1 mm from the baseline is an electrocardiographic presentation of acute myocardial injury. This phenomenon is not confined only to ischemic injury, and various other etiological factors have been described in relation to ST segment elevation. We report the case of a young man who presented in the emergency department complaining of loin pain. He was subsequently found to have transient ST segment elevation, but a thorough evaluation showed no evidence of coronary artery disease. ST segment elevation is one of the best tools for diagnosing acute myocardial infarction, of which reperfusion therapy is the treatment of choice thus making it important to make the diagnosis as quickly as possible. It is equally important, however, not to misdiagnose acute myocardial infarction, as there are other causes of ST segment elevation. Therefore, we report this unique case of renal pain due to stone causing ST segment elevation.

Elevated hsCRP concentrations early in acute coronary syndrome (ACS), prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. Objective: Therefore we aimed to study different follow up measurements of hsCRP levels in acute coronary syndrome patients and to compare the difference between non-ST elevation myocardial infarction (NSTEMI) and ST myocardial infarction (STEMI) patients. Methods: This is an observational study. Of the 89 patients recruited 60 patients had acute myocardial infarction (AMI). Three serial hsCRP levels at baseline on admission to hospital before 12 hours of symptom onset, peak levels at 36-48 hours and follow up levels after 4-6 weeks were analyzed and compared between non-ST elevation AMI and ST elevation AMI. Results: STEMI patients had significantly higher BMI compared to NSTEMI patients. Creatine kinase myoc...

It possesses several advantages due to the unique physiological effects on the lung and ventilation mechanics compared to other modes of oxygen therapy. The use of HFNC is tolerable, comfortable, and easy to set up. Current evidence indicates that the use of HFNC in critically ill patients with coronavirus disease 2019 (COVID-19)-acute hypoxemic respiratory failure (AHRF) is noninferior to noninvasive ventilation in the reduction of endotracheal intubation rate. Early identification of HFNC failure is vital to avoid delaying intubation. However, multiple knowledge gaps exist, and unpowered observational studies limit HFNC incorporation into strong recommendations. The low dispersion of particles demonstrates the feasibility of HFNC; yet, an appropriate setting and precautions should be maximized. Here, we review the recent evidence of HFNC implications in the management o...

We aimed to assess knowledge of cardiopulmonary resuscitation among individuals in Riyadh City, Saudi Arabia, who are not involved in health care. Methods A community-based cross-sectional study was conducted between January and February 2020 in 4 different areas in Riyadh City: North, South, East, and West. The participants were surveyed using a validated self-administered questionnaire. The Statistical Package for Social Sciences version 25.0 was used for inferential statistics and binary logistic regression analysis. Results A total of 856 participants completed the questionnaire, 51.8% were unaware of cardiopulmonary resuscitation. Only 4.4% of the participants had attended a formal cardiopulmonary resuscitation training course, 5.1% were campaign attendees, and 38.7% acquired their experience through the media.

Objectives: Given the numerous recent changes in ICU practices and protocols, we sought to confirm whether favorable effects of telemedicine ICU interventions on ICU mortality and length of stay can be replicated by a more recent telemedicine ICU intervention. Design, Setting and Patients: Observational before-after telemedicine ICU intervention study in seven adult ICUs in two hospitals. The study included 1,403 patients in the preintervention period (October 2014 to September 2015) and 14,874 patients in the postintervention period (January 2016 to December 2018). Intervention: Telemedicine ICU implementation. Measurements and Main Results: ICU and hospital mortality and length of stay, best practice adherence rates, and telemedicine ICU performance metrics. Unadjusted ICU and hospital mortality and lengths of stay were not statistically significantly different. Adjustment for Acute Physiology and Chronic Health Evaluation Version IVa score, ICU type, and ICU admission time via logistic regression yielded significantly lower ICU and hospital mortality odds ratios of 0.58 (95% CI, 0.45–0.74) and 0.66 (95% CI, 0.54–0.80), respectively. When adjusting for acuity by comparing observed-over-expected length of stay ratios through Acute Physiology and Chronic Health Evaluation IVa methodology, we found significantly lower ICU and hospital length of stay in the postintervention group. ICU mortality improvements were driven by nighttime ICU admissions (odds ratio 0.45 [95% CI, 0.33–0.61]) as compared to daytime ICU admissions (odds ratio 0.81 [95% CI, 0.55–1.20]), whereas hospital mortality improvements were seen in both subgroups but more prominently in nighttime ICU admissions (odds ratio 0.57 [95% CI, 0.44–0.74]) as compared to daytime ICU admissions (odds ratio 0.73 [95% CI, 0.55–0.97]), suggesting that telemedicine ICU intervention can effectively supplement low intensity bedside staffing hours (nighttime). Conclusions: In this pre-post observational study, telemedicine ICU intervention was associated with improvements in care standardization and decreases in ICU and hospital mortality and length of stay. The mortality benefits were mediated in part through telemedicine ICU supplementation of low intensity bedside staffing hours.

Normal blood pressure does not always mean good organ perfusion, which means patient might develop septic shock, yet they are not hypotensive. There are several indices that could be used in combination to diagnose and manage hypoperfusion in patients with septic shock. Fluid resuscitation and vasopressor administration along with infection sources control are the cornerstones in septic shock management. This chapter will cover indices that can be used to diagnose hypoperfusion, type and amount of fluid and vasopressor that can be used in resuscitating septic shock patients.

Elevated hsCRP concentrations early in acute coronary syndrome (ACS), prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. Objective: Therefore we aimed to study different follow up measurements of hsCRP levels in acute coronary syndrome patients and to compare the difference between non-ST elevation myocardial infarction (NSTEMI) and ST myocardial infarction (STEMI) patients. Methods: This is an observational study. Of the 89 patients recruited 60 patients had acute myocardial infarction (AMI). Three serial hsCRP levels at baseline on admission to hospital before 12 hours of symptom onset, peak levels at 36-48 hours and follow up levels after 4-6 weeks were analyzed and compared between non-ST elevation AMI and ST elevation AMI. Results: STEMI patients had significantly higher BMI compared to NSTEMI patients. Creatine kinase myoc...

It possesses several advantages due to the unique physiological effects on the lung and ventilation mechanics compared to other modes of oxygen therapy. The use of HFNC is tolerable, comfortable, and easy to set up. Current evidence indicates that the use of HFNC in critically ill patients with coronavirus disease 2019 (COVID-19)-acute hypoxemic respiratory failure (AHRF) is noninferior to noninvasive ventilation in the reduction of endotracheal intubation rate. Early identification of HFNC failure is vital to avoid delaying intubation. However, multiple knowledge gaps exist, and unpowered observational studies limit HFNC incorporation into strong recommendations. The low dispersion of particles demonstrates the feasibility of HFNC; yet, an appropriate setting and precautions should be maximized. Here, we review the recent evidence of HFNC implications in the management o...

We aimed to assess knowledge of cardiopulmonary resuscitation among individuals in Riyadh City, Saudi Arabia, who are not involved in health care. Methods A community-based cross-sectional study was conducted between January and February 2020 in 4 different areas in Riyadh City: North, South, East, and West. The participants were surveyed using a validated self-administered questionnaire. The Statistical Package for Social Sciences version 25.0 was used for inferential statistics and binary logistic regression analysis. Results A total of 856 participants completed the questionnaire, 51.8% were unaware of cardiopulmonary resuscitation. Only 4.4% of the participants had attended a formal cardiopulmonary resuscitation training course, 5.1% were campaign attendees, and 38.7% acquired their experience through the media. Having a higher level of education was p...

Objectives: Given the numerous recent changes in ICU practices and protocols, we sought to confirm whether favorable effects of telemedicine ICU interventions on ICU mortality and length of stay can be replicated by a more recent telemedicine ICU intervention. Design, Setting and Patients: Observational before-after telemedicine ICU intervention study in seven adult ICUs in two hospitals. The study included 1,403 patients in the preintervention period (October 2014 to September 2015) and 14,874 patients in the postintervention period (January 2016 to December 2018). Intervention: Telemedicine ICU implementation. Measurements and Main Results: ICU and hospital mortality and length of stay, best practice adherence rates, and telemedicine ICU performance metrics. Unadjusted ICU and hospital mortality and lengths of stay were not statistically significantly different. Adjustment for Acute Physiology and Chronic Health Evaluation Version IVa score, ICU type, and ICU admission time via logistic regression yielded significantly lower ICU and hospital mortality odds ratios of 0.58 (95% CI, 0.45–0.74) and 0.66 (95% CI, 0.54–0.80), respectively. When adjusting for acuity by comparing observed-over-expected length of stay ratios through Acute Physiology and Chronic Health Evaluation IVa methodology, we found significantly lower ICU and hospital length of stay in the postintervention group. ICU mortality improvements were driven by nighttime ICU admissions (odds ratio 0.45 [95% CI, 0.33–0.61]) as compared to daytime ICU admissions (odds ratio 0.81 [95% CI, 0.55–1.20]), whereas hospital mortality improvements were seen in both subgroups but more prominently in nighttime ICU admissions (odds ratio 0.57 [95% CI, 0.44–0.74]) as compared to daytime ICU admissions (odds ratio 0.73 [95% CI, 0.55–0.97]), suggesting that telemedicine ICU intervention can effectively supplement low intensity bedside staffing hours (nighttime). Conclusions: In this pre-post observational study, telemedicine ICU intervention was associated with improvements in care standardization and decreases in ICU and hospital mortality and length of stay. The mortality benefits were mediated in part through telemedicine ICU supplementation of low intensity bedside staffing hours.

Normal blood pressure does not always mean good organ perfusion, which means patient might develop septic shock, yet they are not hypotensive. There are several indices that could be used in combination to diagnose and manage hypoperfusion in patients with septic shock. Fluid resuscitation and vasopressor administration along with infection sources control are the cornerstones in septic shock management. This chapter will cover indices that can be used to diagnose hypoperfusion, type and amount of fluid and vasopressor that can be used in resuscitating septic shock patients.
