Comorbidities and outcomes among patients hospitalized with COVID-19 in Upper Egypt.

Background: The coronavirus disease 19 (COVID-19) pandemic has spread rapidly around the globe with considerable morbidity and mortality. Coexistence of comorbidities with COVID-19 had consistently been reported as risk factors for unfavorable outcome. We aimed to evaluate the impact of comorbidities in COVID-19 patients on the outcome and determine predictors of prolonged hospital stay, requisite for intensive care unit (ICU) admission. Four hundred and thirty-nine adult patients who are admitted through (June and July 2020) in our University Hospitals were included in the study. All participants were diagnosed with COVID-19 according to Egyptian Ministry of Health guidance as definite case or probable case. Results: Patients with comorbidities represented 61.7% of all cases. Constitutional symptoms especially myalgia and lower respiratory tract (LRT) symptoms such as dyspnea were significantly higher in patients with comorbidities (P < 0.05). Patients with comorbidities had significantly worse laboratory parameters. ICU admission was higher in patients with comorbidities (35.8%). Among different comorbidities 45.4% of cardiovascular diseases (CVD) cases were admitted in ICU followed by diabetes mellitus (DM) cases (40.8%). Also, patients with comorbidities needed invasive mechanical ventilation more than those without comorbidity (31 versus 10.7%, P < 0.001). Significant lower frequency of recovery was found in COVID-19 patients with comorbidities (59% versus 81%, P < 0.001) and death rate was significantly higher in cases with comorbidities (P < 0.001) . The survival rates in cases with pre-existing CVD and neurological diseases were lower than those without disease (P < 0.002 and 0.001, respectively). Conclusions: Association of cardiovascular comorbid conditions including hypertension or neurological diseases including old cerebrovascular strokes together with COVID-19 infections carries higher risks of mortality. However, other comorbidities such as diabetes mellitus, chronic pulmonary or kidney diseases may also contribute to increased COVID-19 severity.

The capacity of primary health care centers in Jordan to manage hypertension: areas for improvement.

The assessment of the capacity of Primary Health Care (PHC) settings for the management of hypertension is essential to identify areas for improving management outcomes. This study aimed to assess the capacity of PHC centers in Jordan to manage hypertension including the assessment of human resources, equipment, and infrastructure. All comprehensive PHC centers located in Irbid and Mafraq governorates in north of Jordan (n = 23) were assessed. An assessment tool from HEARTS Technical Package was adapted and used for assessment. All centers have general practitioners and half of the centers (n = 11, 47.8%) had at least one family doctor working full time. In only one center, all doctors, nurses, and other health workers were trained on the management of hypertension. All centers, except one, had at least one functional automatic blood pressure measuring devices (BPMDs). Almost two thirds of centers (43.5%) had no measuring tapes. ECG machines were present in all centers except two. One third (n = 8, 34.8%) of centers had no functional glucometers. The majority of health centres carry out the laboratory investigations. Educational materials on physical activity, hypertension, and diabetes were seen in four (17.4%) centers only. Necessary medications were always available in the majority of health centers. In conclusion, this assessment revealed many areas for improvement in human resources, equipment, infrastructures, and other resources, such as developing an updated guideline/protocol of hypertension management, training the PHC staff on these guidelines, providing PHC centers with the necessary equipment, and establishing e-registry to improve documentation of data.

Are there differences in cortical excitability between akinetic-rigid and tremor-dominant subtypes of Parkinson's disease?

OBJECTIVE: To assess by transcranial magnetic stimulation (TMS) the excitability of various cortical circuits in akinetic-rigid and tremor-dominant subtypes of Parkinson's disease (PD). METHODS: The study included 92 patients with PD according to UK Brain Bank criteria, with akinetic-rigid (n = 64) or tremor-dominant (n = 28) subtype. Cortical excitability study, including resting and active motor thresholds (rMT and aMT), input-output curve of motor evoked potentials, contralateral and ipsilateral silent periods (cSP and iSP), short and long-interval intracortical inhibition (SICI and LICI), and intracortical facilitation (ICF) were measured. The results obtained were compared to a control group of 30 age- and sex-matched healthy subjects. RESULTS: The patients in the tremor group had significantly lower rMT and aMT compared to controls and akinetic-rigid patients and significantly shorter iSP duration compared to akinetic-rigid patients, while iSP latency tended to be longer in akinetic-rigid patients compared to controls. There were no significant differences between the two PD subgroups regarding other cortical excitability parameters, including paired-pulse TMS parameters. CONCLUSIONS: Only subtle differences of cortical excitability were found between patients with akinetic-rigid vs. tremor-dominant subtype of PD. SIGNIFICANCE: The clinical heterogeneity of PD patients probably has an impact on cortical excitability measures, far beyond the akinetic-rigid versus tremor-dominant profile.

Prognostic role of neurophysiological testing 3-7 days after onset of acute unilateral Bell's palsy.

OBJECTIVE: Recovery from acute Bell's palsy (BP) is variable and there are few predictors of response. We evaluated the usefulness of a range of neurophysiological parameters to predict outcome in BP. METHODS: Fifty-nine patients (age: 33.7±15.4 years) with acute unilateral BP were recruited within 3-7 days of onset. They were evaluated with electroneurography, facial nerve excitability, and the blink reflex. House-Brackmann (HB) clinical scores were obtained at the same time and three months later. All patients received prednisolone treatment and regular rehabilitation. RESULTS: At three months, 41 patients (69.5%) had good recovery, while 18 patients (30.5%) had poor recovery according to the HB scale. The facial nerve excitability threshold and threshold difference between sides were significantly lower in patients with good recovery than those with poor recovery (P values=0.022 and 0.006 respectively). Facial nerve degeneration rate (1 - affected/unaffected amplitude of CMAP of muscle ×100%) recorded in frontalis (P=0.002) and orbicularis oris (P=0.038) were also smaller in good recovery than poor recovery patients. There were no differences in latency and amplitude of CMAPs recorded from frontalis or orbicularis oris muscle, nor in latencies of the components of the blink reflex. ROC analysis showed that patients who had a threshold side difference <13mA (35 cases), had a higher chance of good recovery (85.7% versus 14.3% poor recovery). Patients who had a degeneration rate<50% (38 cases) also had a higher chance of good recovery (78.9%) versus 21.1% who had poor recovery, while patients with a degeneration rate>50% (21 cases) had a 47.8% chance of good recovery versus 52.2% poor recovery (P=0.004). Logistic regression analysis showed that the most significant predictive indicator of BP recovery was the facial nerve degeneration rate of frontalis muscle (P=0.011). CONCLUSION: Facial nerve degeneration rate of frontalis muscle provides the most sensitive prognostic indicator of recovery from acute BP and may provide useful management strategies.

Retrospective review of pediatric status epilepticus in 116 Saudi patients: predictors of outcome.

BACKGROUND: Status epilepticus (SE) is a common, life-threatening condition. Multiple factors are used to predict its outcome and evaluate its risks, and there have been only a few studies in Saudi Arabia. OBJECTIVES: Investigate predictors of SE outcome. DESIGN: Retrospective chart review study. SETTING: Tertiary center, Riyadh. PATIENTS AND METHODS: We reviewed all pediatric cases (age 14 years or younger) of SE admitted between January 2005 and December 2015, collecting data on age, sex, date of birth, developmental status, pre-existing neurological diseases, SE etiology, Glasgow Outcome Scale (GOS) scores, and electroencephalogram (EEG) findings. The outcome was categorized as poor based on any decrease in baseline GOS score or moderate-to-severe developmental delay in young children; otherwise outcome was considered good. MAIN OUTCOME MEASURE: Outcome of SE. RESULTS: One hundred and sixteen patients (54% boys) with ages from 1 month to 10 years were included in the analysis. Fifty-five (47.4%) had a poor outcome. The overall mortality rate related to SE was 2.6%. Four patients had an SE duration of more than 24 hours. Univariate and multivariate analysis revealed that poor outcome was related to symptomatic SE etiology and a history of epilepsy. Age, sex, SE duration, and EEG findings were not predictors of poor outcome. CONCLUSION: Pediatric status epilepticus is highly associated with neurological morbidity. The main pre.dictor of outcome is underlying symptomatic etiology of SE and to a lesser degree the presence of a history of epilepsy. Duration does not seem to play a major role. LIMITATIONS: The main limitation is the retrospective chart review nature of the study with possible bias.
