Validation of an Arabic version of the Cambridge-Hopkins diagnostic questionnaire for restless legs syndrome.

PURPOSE: To validate an Arabic version of the short form of the Cambridge-Hopkins diagnostic questionnaire for restless legs syndrome (CH-RLSq13). METHODS: The Arabic version was created using a standard forward-backward translation method. A pre-final Arabic version was administered with the original English version to a group of bilingual subjects as a pretest. The inter-rater agreement between these two versions was measured. A finalized Arabic version was obtained. For the validation, the Arabic version of the CH-RLSq13 was administered to Lebanese subjects, above 18 years old, selected upon a clinical interview. The diagnosis provided by the Arabic version of the CH-RLSq13 was compared to the clinical diagnosis made by a neurologist at Hotel-Dieu de France hospital. Inter-rater agreement was assessed using Cohen's kappa coefficient. Sensitivity, specificity, and positive and negative predictive values of the translated questionnaire were calculated. RESULTS: Inter-rater agreement, between the 2 versions, for the entire questionnaire, was excellent (κ = 0.950). All items showed a substantial level of agreement between the two versions. In the validation process, 91 participants were included (17 patients diagnosed with RLS and 74 control subjects). The mean age was 40 years, with female predominance. The final Arabic version of the CH-RLSq13 had a sensitivity of 71%, a specificity of 100%, and with negative and positive predictive values of 94% and 100% respectively. CONCLUSION: The Arabic version of the CH-RLSq13 is a reliable tool for the screening and diagnosis of RLS in Lebanese and Arabic-speaking populations.

Physician eye contact in telemedicine video consultations: A cross-cultural experiment.

INTRODUCTION: Eye contact is generally considered a beneficial non-verbal behavior in patient-physician communication. Physicians are advised to simulate eye contact during video consultations by gazing at the camera, although we lack evidence that doing so is beneficial. This work is a cross-cultural experiment that aims to answer: "Are physicians who gaze at the camera during video consultations perceived as making eye contact, and are their communication skills rated higher?" METHODS: 43 Japanese and 61 Lebanese participants watched videos of physicians providing the same video consultations while gazing at the camera and screen. After watching each video, they rated the physicians' communication skills using six items from the GCRS and the MAAS-G scales. They also picked and justified their preferred physician gaze direction. RESULTS: When physicians gazed at the camera, they were perceived as making more eye contact and received higher communication and interpersonal skills ratings, both in Japan and Lebanon. The effect of gazing at the camera was consistently positive but varied by country and consultation content. In Japan, simulating eye contact improved the ratings of the attentive and caring physician, whereas in Lebanon, it improved the ratings of the tired and inattentive physician. When asked to choose their preferred gaze direction, 88.4% of Japanese and 90.2% of Lebanese participants chose camera gaze over screen gaze due to its positive effect on patient feelings and physician perception. Participants who chose screen gaze noted the unnaturalness of gazing at the camera and its potential negative impact on care quality. CONCLUSION: Physicians providing video consultations can simulate eye contact by gazing at the camera. Doing so improves their communication and interpersonal skills ratings and could potentially enhance their communication with their patients. Mainstream video conferencing platforms could implement gaze correction methods to simulate eye contact without affecting the physicians' experience and capacity to provide quality care.

Physician Communication Skills in Telemedicine: The Role of Eye Contact.

Gaze is an important non-verbal behavior in patient-physician communication. We examine the effect of the physician's gaze direction in video consultations on their communication and interpersonal skills ratings. 51 subjects watched videos of a physician providing the same teleconsultations while (a) looking directly at the camera and (b) looking at the computer screen. After each video, the participants rated the physician's skills. The results showed that looking at the camera is perceived as making eye contact and is associated with higher ratings on two communication skill items: (1) using empathy to communicate appreciation of the patient's feelings, and (2) providing support by expressing concern, understanding, and willingness to help. The effect of eye contact depended on the content of the consultation and on the general attitude of the physician. These results highlight the role of eye contact in video consultations and its dependency on other verbal and non-verbal behaviors.

Ensuring Care Continuity in Extreme Crises: A Participatory Action Research Approach.

The Lebanese healthcare system has been facing major challenges due to an unprecedented financial crisis, socio-political instability, and the COVID-19 pandemic. This study aims to examine the impact of overlapping major crises on care continuity and to propose IT-based solutions to address current challenges and build future resilience. To this end, we adopted a participatory action research approach and conducted a two-phase qualitative study - six semi-structured interviews followed by three future workshops with local stakeholders including physicians and interns practicing in Lebanon. Through the interviews, we identified the primary consequences of the crises and the ways they impacted the continuity of care. We also identified adaptation mechanisms used by physicians and patients to ensure continuity of care. Through the future workshops, we identified various IT-based solutions that could be implemented to tackle existing challenges and support local adaptation attempts.

Validity and reliability of an Arabic version of the Sleep Hygiene Index.

AIM: this study aims to assess the reliability and validity of an Arabic version of the Sleep Hygiene Index (SHI). METHODS: A methodological study was carried out in four stages: initial translation by 2 professional translators, evaluation and synthesis of the initial translation by project managers, back-translation and validation. The Arabic (SHI-AR) and English (SHI-ENG) versions of the SHI were administered across Lebanon as an anonymous online survey in April 2020. Internal consistency of the SHI-AR and inter-rater reliability were assessed by calculating Cronbach alpha (α) and Intraclass Correlation Coefficient (ICC) respectively. Inter-rater agreement for each item of the SHI was measured using Cohen's Kappa coefficient. Construct validity was investigated by exploratory factor analysis (EFA). RESULTS: 363 participants were enrolled in the study (129 men, 234 women, mean age 30 ± 11 years). There was no statistically significant difference between mean overall scores on the 2 versions of the SHI with mean scores of 19.16 ± 7.4 and 19.25 ± 7.6 on SHI-AR and SHI-ENG respectively (p = 0.265). Internal consistency was satisfactory (α = 0.749), and the inter-rater agreement for the total scores of the 2 versions of the SHI was excellent (ICC = 0.980). All items of the SHI showed substantial to high level of agreement between the 2 versions. EFA established four factors underlying the questionnaire. CONCLUSION: The Arabic version of the SHI is a valid tool to assess sleep hygiene in Arabic speaking populations.

Urodynamics in patients with multiple sclerosis: is it necessary? A randomized-controlled trial.

BACKGROUND: The need for complete urodynamic evaluation in Multiple Sclerosis (MS) patients with Lower Urinary Tract Symptoms (LUTS) is not fully established in the literature. The objective was to evaluate the effect of urodynamics in MS patients with LUTS on treatment outcomes. METHODS: MS patients with LUTS were recruited. On their first visit, urinary symptoms, symptom bother and urologic quality-of-life were evaluated using standardized questionnaires. On their second visit, patients were randomized into two groups: Group A underwent uroflowmetry, and Group B underwent a urodynamic study. Patients received treatment based on the whole evaluation and then were evaluated at 1, 3 and 6 months. RESULTS: Fifty MS patients with LUTS were randomized to 25 patients in each group. All scores decreased significantly after 6 months of treatment in both groups (p < 0.05). However, no differences were found between the two groups at baseline and at 1, 3 and 6 months of treatment (p > 0.05) concerning treatment outcomes. CONCLUSION: A detailed clinical and non-invasive evaluation of MS patients with LUTS seems to be sufficient for prescribing an effective treatment. A urodynamic study does not influence the response to the prescribed treatment in terms of LUTS severity, bother or urologic quality-of-life.

The Effect of the COVID-19 Pandemic on Physicians' Use and Perception of Telehealth: The Case of Lebanon.

The COVID-19 pandemic forced physicians to quickly adapt and find ways to provide their usual offline services by using online tools. We aimed to understand how physicians adapted to the sudden need for telehealth and if their perception of telehealth changed due to their experience during the COVID-19 pandemic. We conducted an exploratory sequential mixed-methods study. We interviewed five Lebanese physicians and thematically analyzed the interviews. We developed a questionnaire based on the analysis results and administered it online to physicians in Lebanon. In total, 140 responses were collected. We found that, during the COVID-19 pandemic, physicians engaged in more telehealth activities in the realms of telemedicine, public awareness, continuing medical education, research, administration, and teaching. They also expanded their repertoire of information-technology tools. Our results also show that there was a significant shift in the physicians' perceptions, indicating greater openness and willingness to adopt telehealth services. However, a significant amount of skepticism and uncertainty regarding telemedicine remains, especially concerning its efficiency, safety, and the adequacy of existing regulations. Based on our findings, we offer recommendations for health IT policy makers, developers, and researchers, to sustain the continuity of telehealth activities beyond the COVID-19 pandemic.

The use of mirabegron in neurogenic bladder: a systematic review.

PURPOSE: To evaluate the use of mirabegron in patients with neurogenic bladder. METHODS: A systematic review of the literature was conducted using four databases (Medline via PubMed, Scopus, Cochrane, and EMBASE). Articles evaluating mirabegron in neurogenic bladder patients were collected, and assessment of the drug's efficacy was reviewed according to clinical and urodynamic parameters. RESULTS: Seven studies were selected and a total of 302 patients with NB were evaluated, ranging from 15 to 66 patients per study. All of the patients had received antimuscarinics as a previous treatment modality. Mirabegron was used as a second-line treatment after antimuscarinics lacked efficacy or caused adverse effects. The duration of the treatments ranged from 4 to 12 weeks. Reported in two studies each, bladder compliance and maximal cystometric capacity were the most commonly improved urodynamic parameters. In the majority of the studies, positive outcomes were reported for clinical scores. Additionally, analysis of the IPSS subscores revealed an improvement of storage symptoms as opposed to voiding symptoms. In all of the studies, mirabegron was well tolerated. CONCLUSION: Mirabegron appears to be an effective treatment in the management of neurogenic bladder unresponsive to antimuscarinics, particularly in patients presenting with storage symptoms. There is still no evidence concerning the use of mirabegron as a first-line therapy for neurogenic bladder.

Longitudinal Extensive Transverse Myelitis in an Immunocompetent Older Individual-A Rare Complication of Varicella-Zoster Virus Reactivation.

Varicella-zoster virus (VZV) is a human neurotropic herpes virus that causes chickenpox in children. After becoming latent in dorsal root ganglia, it can reactivate to cause dermatological manifestations, the most common one being shingles or herpes zoster. Severe neurologic dysfunctions can occur in immunocompromised patients such as encephalitis, meningitis, myelitis and neuropathy. Longitudinal extensive transverse myelitis (LETM) is an unusual neurological complication mainly described in immunocompromised patients, with very few cases described in immunocompetent ones. We hereby report a case of VZV-induced LETM in an immunocompetent older adult-a situation rarely described in the literature. LETM is a rare complication of VZV and its pathogenesis; therapeutic interventions and prognosis are far from being fully clarified. However, a prompt diagnosis is needed to allow a rapid initialization of treatment and ensure a better outcome. Although the therapeutic lines are not clear, immunosuppressive agents may have their place in cases of unsuccessful results and/or relapses following acyclovir coupled with a well conducted methylprednisolone therapy. Further studies are highly needed to improve the current understanding of the disease course and mechanisms, and to optimize therapeutic strategies.
