The burden in family caregivers of people living with dementia: prevalence and predictors.

BACKGROUND: Providing care for people with dementia incorporates a level of burden which can affect quality of life for both the caregiver and the recipient of care. This study measures the level of burden experienced by Jordanian caregivers for people with dementia and explore related predictors. METHODS: Through a cross-sectional survey, participants were invited through convenience sampling to participate in a structured interview. RESULTS: A total of 406 participants completed the survey. According to Zarit Burden Interview, the mean burden score of the sample was 26.2 (SD = 16.2). This score falls under the mild to moderate burden level. Older age of the patient, severe dementia, lower number of caregivers, if the caregiving negatively affected family relations, and if the caregiving negatively affected jobs, were significant predictors of burden. CONCLUSION: Caregivers in the current study reported no burden to a minimum burden. This result does not mean that these caregivers have no or minimal stress or that they do not have psychological needs; on the contrary, these results call for more attention to providing extra psychological and emotional support to caregivers of patients with dementia in order to decrease the burden level and maintain their efforts in caregiving. Future studies are required to discern the shape and context of unmet caregiver needs, assessment, and support.

Trends of Prevalence Estimates and Risk Factors of Depressive Symptoms among Healthcare Workers Over one Year of the COVID-19 Pandemic.

Background: COVID-19 pandemic has an overwhelming psychologic burden on healthcare workers (HCWs). This study aims to investigate the changes in the prevalence, estimates, severity, and risk factors of depressive symptoms among HCWs within the first year of the COVID-19 pandemic. Methods: An observational e-survey collected data on HCWs' socio-demographic characteristics, occupational situation, and depressive symptoms as measured by Patient Health Questionnaire-9 (PHQ-9). The e-survey was distributed one month after the onset of the COVID-19 pandemic (onset group) and again after one year (one-year group). Results: A total of 422 HCWs were included (Mean (SD) age, 35.3 (9.9) years; 71.3% males), with 211 (50%) participants in each group. In the total cohort, the mean PHQ-9 score was 8.5, and 36.7% reported clinically significant levels of depressive symptoms with a PHQ-9 score of ≥10. Compared to the onset group, the one-year group reported a higher risk of major depressive disorder (41.7% vs. 31.8%; OR 1.538; 95%CI 1.032-2.291; p=0.034), a higher mean PHQ-9 score (9.5 (6.8) vs. 7.4 (5.3), p<0.001), and more severe depressive symptoms (p<0.005). Participants who were younger, unmarried, underwent testing for COVID-19, reported lower monthly income, did not receive special COVID-19 education, or had lower satisfaction with institutional preparedness had significantly higher depression scores and symptoms in both onset and one-year groups (p<0.05 for each category). Female gender and direct contact with COVID-19 patients or samples were significant risk factors within the onset group. Occupation as a physician, history of COVID-19 testing or infection, and perception of significant changes in work schedule or intensity were significantly associated with higher depression scores and symptoms among the one-year group. Conclusion: This study sheds light on an unspoken but significant rise in prevalence estimates and severity of depressive symptoms among HCWs over a year of the COVID-19 pandemic and shows the vulnerable subgroups for whom a psychological intervention might be warranted.

Prevalence of seropositivity of selected herpesviruses in patients with multiple sclerosis in the North of Jordan.

BACKGROUND: Multiple sclerosis (MS) is a neurological disease that is caused by an autoimmune response that results in the neuron's demyelination in the central nervous system. The exact etiology of MS is not clear; however, several environmental and genetic factors are believed to participate in its initiation and development, including exposure to viruses. This study aims to investigate the association between the seropositivity and antibody titer of selected herpesviruses and MS in Jordanian MS patients. METHOD: In this study, 55 MS patients and 40 age- and gender-matching apparently healthy volunteers were recruited from two main hospitals in the north of Jordan. MS patients were grouped into three types of MS based on the clinical presentation of the disease. Blood samples were collected from the participants and the IgG antibodies for human herpesvirus 6 (HHV-6), Epstein-Barr virus (EBV) nuclear antigen (EBNA), EBV viral capsid antigen (VCA) and varicella-zoster virus (VZV) were assayed by ELISA. The prevalence of seropositivity and the antibody level for each of the antibodies were compared between MS patients and controls and between the three types of MS. RESULTS: There was no significant difference in the prevalence of seropositivity and in the levels of antibodies for HHV-6, EBNA and VCA between MS patients and controls and between the three types of MS. In contrast, the number of seropositive patients and the level of IgG antibodies for VZV were significantly higher in MS patients compared to the control. CONCLUSION: This study showed that patients with MS in the north of Jordan were more likely to be seropositive for VZV than the general population. Based on this finding, we recommend further studies to evaluate the seropositivity to VZV to be carried out in other parts of Jordan and the greater middle east to find out if there is a correlation between MS and previous infection with VZV.

Clinical characteristics and management outcomes of Guillain-Barré syndrome: eight-year experience at a tertiary center in jordan - a retrospective cohort study.

Guillain-Barré syndrome (GBS) is a major cause of acute flaccid paralysis that is encountered in all geographical areas. Very limited data about this syndrome has been reported from the Arab countries. This study is the first one trying to describe the clinical features and management outcomes of GBS in the Jordanian population. Methods: This retrospective study looks at adult patients admitted to a major tertiary referral hospital in the north of Jordan between 2013 and 2021. Results: A total of 30 patients met the inclusion/exclusion criteria. Males were predominantly affected (70%) with a male-to-female ratio of 2.33. Acute inflammatory demyelinating polyradiculoneuropathy variant was encountered in 60% of cases, whereas axonal variants, namely, acute motor axonal neuropathy and acute motor axonal and sensory neuropathy variants were seen in about 23% of cases. ICU admission was reported in 37% of patients and 6.7% required mechanical ventilation. Most patients had a favorable outcome with a GBS disability score of three or better at out-patient follow-up visits. Conclusion: Our cohort of patients showed a significant deviation in disease expression from that reported in other parts of the globe. This deviation was obvious in more prominent male predominance, frequencies of different GBS variants, and more favorable short-term morbidity/mortality outcomes. However, larger multicenter prospective studies are needed for confirmation of these results.

Effect of 2% Topical Lidocaine Gel on Discomfort from Electrical Stimulation During Nerve Conduction Studies- A Prospective Double-Blind Placebo-Controlled Study.

Purpose: Procedure discomfort can limit electrodiagnostic studies. Reducing discomfort can maximize the benefits of these diagnostic tools. This study targeted the discomfort associated with nerve conduction studies (NCS). Patients and Methods: This was a prospective randomized double-blind placebo-controlled study comparing the effect of topical lidocaine gel (2%) versus analgesic-free lubricant gel (K-Y gel) on pain perception during NCS. Sequential patients (n=130) referred for routine NCS participated in the study. We applied 1 mL of lidocaine gel to one palm, and 1 mL of K-Y gel to the other as a control. After 20-45 min of application, graded increments of electrical stimulation intensity were delivered to record the median and ulnar mixed palmar nerve responses. Patients were then asked to score the degree of pain felt from electrical stimulation over each palm using the Wong-Baker Faces Pain Scale (WBFPS) and the Numeric Rating Scale (NRS), independent of baseline pain. Results: Mean WBFPS and NRS scores for lidocaine-treated palms were significantly lower than those for controls using parametric paired t-test (3.79 vs 4.37 and 3.35 vs 3.78 respectively, all p-values<0.05). Subgroup analysis showed a significant decrease in mean scores in females, patients aged ≤50 years, patients without a history of previous NCS, and patients without comorbidities (all p-values<0.05). Median scores using nonparametric Wilcoxon ranked test also showed statistically significant differences (all p-values<0.05). Conclusion: The results indicate that topical lidocaine 2% gel reduces discomfort associated with NCS. However, despite the statistical significance, clear clinical significance may be lacking. Clinical implementation may be considered for the subgroups that showed the greatest benefit. Further studies that incorporate more efficient drug delivery methods may yield better results.

Annual Period Prevalence and Risk Factors of Dementia Among Older Jordanian Hospitalized Patients.

BACKGROUND: The number of people living with dementia is forecasted to increase rapidly, particularly in developing and underdeveloped countries. No epidemiological studies of dementia have been reported in Jordan; therefore, the number of people living with dementia and the risk factors are unknown. OBJECTIVE: Measure the annual period prevalence of dementia, along with its risk factors in Jordanian hospitalized patients over the age of 50 years. METHODS: The prevalence of dementia was measured using a prospective survey design for over one year. Risk factors were explored using a case-control match design. RESULTS: The total number of participants in the overall survey was 31,411, and the number of participants included as cases with dementia was 406, the number of matched controls free of dementia was 416. The general annual period prevalence of dementia for people older than 50 years was 1.29%, comprising 406 patients. Multivariate analysis revealed that older age, male gender, family history of dementia, and illiteracy were significant risk factors for dementia. CONCLUSION: The prevalence of dementia in Jordan is lower than the global prevalence due to the relatively younger Jordanian population. Results from this study can provide baseline information for policymakers for significant health planning to meet the needs of such a group of patients.

A 73-Year-Old Woman with Respiratory Failure and Stimulus-Induced Rhythmic, Periodic, or Ictal Discharges (SIRPIDs) in the Absence of a Detectable Brain Insult Diagnosed and Monitored by Continuous Electroencephalogram (EEG) and Treated with Valproate, Carbamazepine, and Clonazepam.

BACKGROUND Stimulus-induced rhythmic, periodic, or ictal discharges (SIRPIDs) commonly occur in critically ill patients and can be distinguished from spontaneous epileptic seizures by continuous electroencephalogram (CEEG) monitoring. There are no current treatment guidelines for SIRPIDs. This report is of a 73-year-old woman with respiratory failure and without any detectable gross brain lesions. She had developed SIRPIDs, which were diagnosed through CEEG monitoring. She responded well to valproate, carbamazepine, and clonazepam. CASE REPORT A 73-year-old woman was admitted to the intensive care unit (ICU) with a chest infection. After 3 days, this infection was complicated by respiratory failure and coma, for which she was intubated. After that, recurrent brief episodes of abnormal head and right upper limb jerky movements with right gaze deviation occurred. Nurses noticed that these episodes occurred exclusively upon physical interaction with the patient, and lasted up to 3 minutes. No focal findings were noted on neurological examination. The brain computed tomography (CT) scan revealed no acute brain insult. CEEG revealed SIRPIDs, which abated with midazolam boluses, followed by infusion at 15 mg/hour. Later, they were controlled by valproate, carbamazepine, and clonazepam in succession, guided by CEEG data. CONCLUSIONS This report shows the importance of CEEG monitoring to diagnose SIRPIDs and monitor treatment response. It also suggests that SIRPIDs can occur even in the absence of gross brain pathology. Although there are no current treatment guidelines for SIRPIDs, the use of valproate, carbamazepine, and clonazepam can help control them, as evidenced in this case.

Serum vitamin d inversely correlates with depression scores in people with multiple sclerosis.

BACKGROUND: Vitamin D (Vit.D) deficiency is a risk factor for multiple sclerosis (MS) and correlates with its severity. Depression is also common in people with MS (PWMS). We aim to investigate Vit.D correlation with depression risk scores in PWMS. METHODS: A cross-sectional cohort of PWMS were studied. Clinical and demographic data were collected. The Hospital Anxiety Depression Scale (HADS) and the Beck Depression Inventory-II (BDI-II) were used to evaluate the risk of depression. Expanded Disability Status Scale (EDSS) and Patient Determined Disease Steps (PDDS) were used to evaluate the disability. Serum concentrations of 25-hydroxyvitamin D were measured. Bivariate and partial correlations of Vit.D status and scores of depressive and disability scales were statistically analyzed. The IBM Statistical Package for Social Sciences software, version 25.0, was used for data processing. RESULTS: A total of 88 PWMS were enrolled. More than half of them had potential depression, and 68% had below-normal serum Vit.D levels (normal ≥ 30 ng/ml, insufficient = 21-29 ng/ml, and deficient ≤ 20 ng/ml). Serum Vit.D levels significantly correlated with scores of depression scales in both males and females, which was more robust in males. This association was maintained with a partial correlation analysis controlling for age, sex, body mass index, disease duration, type of MS, and EDDS HADS: r=-0.513, p<0.001; BDI-II: r=-0.401, p<0.001). Serum Vit.D had significant inverse correlations with EDSS score (r=-0.353, p = 0.001) and PDDS score (r=-0.341, p = 0.001), with more robust correlations in females compared to the whole group. CONCLUSION: Vit.D levels correlate with depression risk scores in PWMS with differential sex effects.

Diagnostic value of electrocardiogram during routine electroencephalogram.

INTRODUCTION: A single-lead electrocardiogram (EKG) is routinely recorded with electroencephalogram (EEG). This study investigates the frequency and types of EKG abnormalities during routine EEG. METHODS: All routine EEGs (20-60 min) over one year were retrospectively analyzed. A blinded cardiologist interpreted EKG recordings. An epileptologist evaluated EEGs. Demographic data, underlying comorbidities, and indications for the EEG were extracted. RESULTS: A total of 433 recordings for 365 patients were included. Mean (±SD) age was 46.8 (±21.3) years and 50.4% were females. EKG abnormalities were detected in 28.5% of patients; sinus tachycardia (11%), premature ventricular contractions (7.9%), atrial fibrillation (Afib) (6.3%), sinus bradycardia (2.2%) and premature atrial contractions (1.1%). Afib was more common in females than males (p = 0.020), confirmed in six out of seven patients and discovered in 17 patients. Age (OR: 1.67, 95%CI: 1.05-2.66, p = 0.031), prior diagnosis of epilepsy (OR: 2.25, 95% CI: 1.22 - 4.14, p = 0.009), history of seizure (OR: 1.97,  95%CI: 1.09-3.54, p = 0.024), abnormal EEG (OR: 2.14, 95%CI: 1.25 - 3.66, p = 0.005) and EEGs evaluating seizures/epilepsy (OR: 4.18, 95% CI: 1.32 - 13.21, p = 0.015) or syncope (OR: 3.21, 95% CI: 1.16 - 8.84, p = 0.024) were independently associated with abnormal EKG. CONCLUSION: The frequency of EKG abnormalities captured during routine EEGs was high, with Afib being the most significant. Older age, history of epilepsy or seizure, abnormal EEGs, and EEGs evaluating seizures/epilepsy or syncope were significant predictors. These findings suggest neurologists to become more vigilant to EKG recorded during routine EEG as such findings might have diagnostic and therapeutic implications.

A Rare Case with New Insights: Pure Sensory Guillain Barre Syndrome with Axonal Features.

The pure sensory variant of Guillain-Barré syndrome "GBS" is controversial. Scarce case reports in the literature have described pure sensory presentations secondary to acute demyelination of peripheral sensory nerves. Pure sensory GBS secondary to axonal damage is rarer and even more controversial owing to a significant overlap with sensory neuronopathy. A 31-year-old lady with history of a recent primary varicella zoster virus (VZV) infection presented with acute onset of sensory symptoms and signs involving her four limbs and the trunk, without weakness. Examination was remarkable for severe impairment in all sensory modalities in her limbs and trunk, pseudo-athetoid limb movements, sensory ataxia, positive Romberg's sign, and areflexia, with no motor involvement. CSF analysis showed elevated protein without pleocytosis known as albuminocytological dissociation. MRI of the spine with contrast showed multiple root enhancement. Nerve conduction studies "NCS" demonstrated absent sensory action potentials, with normal motor nerves responses. Initial electromyography was normal. After differential diagnoses were appropriately excluded, the patient was diagnosed with pure sensory axonal GBS and treated with IVIG for five days. Gradual clinical improvement was seen over the following months, with improvement in six-month GBS disability score down to two. Follow-up NCS showed findings similar to the initial study but follow-up EMG studies revealed denervation potentials in multiple levels, suggesting a subclinical axonal motor involvement and excluding sensory neuronopathy. To our best knowledge, this case represents the first case of pure sensory GBS with onset after a documented primary VZV infection. The findings in this case illustrate the difficulties in diagnosing pure sensory GBS and the significance of an early treatment. It also demonstrates the potential value of follow-up EMGs in excluding sensory neuronopathy as an important differential diagnosis for this condition.

Carpel tunnel syndrome: A link with vitamin D and calcium.

Carpal tunnel syndrome (CTS) and vitamin D deficiency are two conditions that cause chronic pain and are thus associated with psychological issues as well. The aim of the present study was to evaluate vitamin D levels, daily calcium intake, musculoskeletal pain and psychological symptoms in patients with CTS. The study included 48 patients with CTS and age-sex matched controls. Serum vitamin D levels were measured, and psychological symptoms were assessed using a Hospital Anxiety and Depression Scale. A Pain DETECT questionnaire was used to assess musculoskeletal pain (MSP) sites and severity. The results showed that vitamin D deficiency was considerably more prevalent in patients with CTS (95.8%) compared with controls (22.9%). Clinical anxiety (35.4 vs. 6.3%) and clinical depression (29.2 vs. 4.2%) were also more common in patients with CTS compared with controls. All the patients with CTS exhibited MSP, whereas none of the controls reported any MSP. Anxiety was significantly and inversely associated with vitamin D levels (r2=-0.482; P<0.01), total daily calcium intake (r2=-0.294: P<0.05), and positively associated with body mass index (BMI; r2=0.200; P≤0.05) and depression (r2=0.587; P<0.01). Depression was significantly and inversely associated with vitamin D levels (r2=-0.269; P<0.01) and total daily calcium intake (r2=-0.236; P<0.05). Logistic regression analysis showed that with every unit increase in serum vitamin D levels, the odds of CTS were decreased 1.22x. While a one-unit increase in anxiety total score was associated with a 14% increase in the odds of having CTS after adjusting for different confounders. In conclusion, vitamin D deficiency, MSP and psychological symptoms are common in patients with CTS. Serum vitamin D levels and anxiety were significant independent predictors of CTS. Based on the results of the present study, it was shown that housewives had an equivalent chance of suffering from CTS morbidity as other high-risk professions. Further studies are required to confirm if vitamin D supplementation could prevent the onset of CTS.

Epidemiology, Risk Factors, and Predictors of Disability in a Cohort of Jordanian Patients with the First Ischemic Stroke.

OBJECTIVE: To identify the risk factors, etiologies, length of stay, severity, and predictors of disability among patients with the first ischemic stroke in Jordan. METHODS: A retrospective cohort study of 142 patients who were admitted to the Neurology Department at King Abdullah University Hospital between July/2017 and March/2018 with a first ischemic stroke. Etiology was classified according to the TOAST criteria. Severity was represented by NIHSS score, disability by mRS score, and prolonged length of stay as hospitalizations more than 75th percentile of the cohort's median length of stay. Analysis of the sample demographics and descriptive statistics were done, including frequencies of prevalence of independent variables (risk factors) and frequencies of stroke and etiology work-up. Chi-square and univariate analysis of variance "ANOVA" were used to investigate the relationship between risk factors and type of stroke. Finally, logistic regression analysis was used to measure the contribution of each of the independent variables. IRB approval was obtained as necessary. RESULTS: The mean age for the cohort was 66.5 years. The most common risk factors were hypertension (78.8%), diabetes mellitus (60.5%), and ischemic heart disease (29.4%). The most common stroke etiology was small-vessel occlusion (54.2%). Median length of stay was 4 days. Prolonged length of stay was observed in 23.23% of patients, which was associated with several factors, the most common of which were persistent dysphagia (57.5%), nosocomial infection (39.3%), and combined dysphagia and nosocomial infection (21.2%). The mean admission NIHSS score was 7.94, and on discharge was 5.76. In-hospital mortality was 2.81%, while 50% of patients had a favorable outcome on discharge (mRS score between 0-2). The mean discharge mRS score for the cohort was 2.47 (SD ± 1.79). Large artery atherosclerosis was associated with the highest residual disability with a mean score of 3.67 (SD ± 1.88), while the stroke of undetermined etiology was associated with the lowest residual disability with a mean score of 1.60 (SD ± 1.78). Significant predictors of mRS score were smoking (t 3.24, P < 0.001), age (t 1.98, P < 0.049), and NIHSS score (t 9.979, P 0.000). CONCLUSION: Ischemic strokes have different etiologies that are associated with different levels of impact on the patient's clinical status and prognosis. Large artery atherosclerosis was associated with the highest residual disability. Regarding predictors of prognosis, current smoking status, age above 50, gender, and NIHSS on admission appear to be the strongest predictors of prognosis. Finally, higher NIHSS score on admission resulted in a longer hospital stay.
