In Vitro Activity of Ceftazidime-Avibactam Against Enterobacteriaceae and P. aeruginosa Isolated at the Ibn Rochd University Hospital of Casablanca.

BACKGROUND: The aim of this study is to determine the in vitro activity of ceftazidime-avibactam (CZA) on Entero-bacteriaceae and P. aeruginosa strains isolated in the bacteriology-virology laboratory of the Ibn Rochd University of Casablanca. METHODS: This is a prospective descriptive longitudinal study conducted from May 28 through June 25, 2022, on Enterobacteriaceae and P. aeruginosa isolated from diagnostic samples received at the Bacteriology-Virology and Hospital Hygiene Laboratory of the Ibn Rochd University Hospital of Casablanca. The isolation and identification of the strains were carried out using standard bacteriological techniques. The study of sensitivity to ceftazidime-avibactam was done by diffusion susceptibility testing on agar medium according to EUCAST 2022 recommendations. RESULTS: During the study period, 271 strains of Enterobacteriaceae were isolated. The sensitivity rate to ceftazidime-avibactam was 91% vs. 74% for ceftazidime alone. R. terrigena was the most resistant strain to CZA with a rate of 69%, followed by E. cloacae (14%), then K. pneumoniae (6%), and finally E. coli (5%). Among the strains isolated, 24% (n = 66) produced ESBL, of which 29% (n = 19) were resistant to CZA, and 10.7% (n = 29) were re-sistant to imipenem, including 44, 8% (n = 13) that were resistant to imipenem and CZA. Regarding P. aeruginosa, 92 strains were isolated. The CZA resistance rate was 33.6% (n = 31). Among the strains isolated, 30.4% (n = 29) were resistant to imipenem, of which 82.7% (n = 24) were resistant to CZA. CONCLUSIONS: The in vitro evaluation of the ceftazidime-avibactam activity on the strains isolated, mainly: E. Coli, K. Pneumoniae, and E. Cloacae, showed a good inhibitory activity of this molecule which can constitute a therapeutic alternative for the treatment of infections due to these microorganisms.

The Performance of GeneXpert in the Diagnosis of Lymph Node Tuberculosis: A Prospective Study Comparing GeneXpert and Culture Findings.

Background and objective Lymph node tuberculosis (LNTB) is a common manifestation of extrapulmonary tuberculosis (EPTB). GeneXpert is a rapid diagnostic molecular test that simultaneously detects tuberculosis and rifampicin (RIF) resistance. In this study, we aimed to assess the epidemiology of LNTB and diagnostic performance parameters of the GeneXpert in routine ENT practice. Methods We conducted a cross-sectional prospective study from January to July 2019, in the Department of Otorhinolaryngology and Head Neck Surgery at the Hassan II University Hospital Center of Fez, Morocco. The samples were collected using lymph node biopsy and subjected to GeneXpert assay, culture, and histopathology. Diagnostic performance parameters of the GeneXpert were calculated and compared with culture. Results All patients with cervical adenopathy were included. Lymph node biopsies were performed for all patients. The performance of the GeneXpert was assessed according to culture findings. Among the 75 cases, the mean age was 21.6 ± 12.7 years with a female predominance (60%). GeneXpert was positive in 66.7% of specimens. The sensitivity and specificity of the GeneXpert assay were 78.6% and 40.4% respectively. GeneXpert accuracy was 54.6%. The positive predictive value (PPV) and negative predictive value (NPV) were found to be 44% (95% CI: 30.2-57.8) and 76% (95% CI: 59.3-92.7) respectively. Mycobacterium bovis was isolated in all samples, with no case of resistance to RIF found. Conclusions The performance of GeneXpert was found to be superior in terms of establishing the diagnosis of LNTB. It offers speedy and prompt results and clinicians should adopt it in routine clinical practice.

Bibliometric analysis of COVID-19 research in Morocco: short communication.

As a global pandemic, coronavirus disease 2019 (COVID-19) has led to a growing number of related research studies being published worldwide. However, there is no study on the bibliometric analysis of these Moroccan studies. This study aims to provide a general overview of COVID-19 studies in Morocco and may provide a direction for hot topics and future research trends. Method: The global literature about COVID-19 published between 2019 and 2022 was scanned in PubMed, the Web of Science collection database, Scopus, and two preprint platforms. 'COVID-19', 'Novel Coronavirus', '2019-nCoV', and 'SARS-CoV-2' were used as the keywords to reach the relevant publications. The VOS viewer was applied to perform the bibliometric analysis of these articles. Results: A total of 987 Moroccan publications on the topic of COVID-19 were retrieved. Of all these publications, 166 (61.9%) were original journal articles, 10 (3.7%) were review articles, 514 (8.38%) were letters and 56 (20.9%) were others, such as case reports, notes, or book chapters. Ten original articles (3.7%) had not yet been peer-reviewed and were retrieved from the preprint servers medRxiv and bioRxiv. The highest number of COVID-19 publications was published by Mohammed V University in Rabat (n=45, 16.8%), followed by Hassan II University (n=32, 11.9%) and Mohammed VI University of Health Sciences (n=29, 10.8%). The open-access format was the predominant publishing model (43.2%) and 92.9% were written in English. The main research lines identified in COVID-19 for Morocco are related to the pandemic's indirect effects: education (11.2%), mental health (6.3%), and the environment (6.3%). Conclusion: Moroccan institutions have made a profound contribution to COVID-19 research than that in other African countries, but lags behind compared to that in Arabic countries.

Prevalence of Sleep Disturbances in Latin American Populations and Its Association with Their Socioeconomic Status-A Systematic Review and a Meta-Analysis.

BACKGROUND: The worldwide increase in the prevalence and incidence of sleep disturbances represents a major public health issue. Among multiple determinants affecting sleep health, an individual's socioeconomic status (SES) is the most ignored and underestimated throughout the literature. No systematic review on the relation between SES and sleep health has been previously conducted in Latin America. METHODS: PRISMA guidelines were used. RESULTS: Twenty articles were included in the final sample (all cross-sectional studies), and twelve among them were rated as fair or poor quality. Among these studies, 80.0% (n = 16) were performed in Brazil, 10.0% (n = 2) were performed in Peru, 5.0% (n = 1) were performed in Chile, and 5.0% (n = 1) were multicentric (11 countries). The combined total number of participants was N = 128.455, comprising 3.7% (n = 4693) children, 16.0% (n = 20,586) adolescents, and 80.3% (n = 103,176) adults. The results show the following: (1) The sleep outcomes analyzed were sleep duration, sleep quality/sleep disturbance, insomnia, excessive daytime sleepiness (EDS), obstructive sleep apnea (OSA)/sleep-disordered breathing (SDB) symptoms, and bruxism. (2) The most used determinants were income, education level, employment status/occupation, wealth/assets, and composite indices. (3) Higher SES was associated with shorter sleep duration. (4) Lower SES was associated with a decrease in sleep quality, less frequent snoring, more prevalent EDS, and sleep bruxism. (5) Lower education was associated with insomnia. (6) Higher education was associated with more sleep bruxism. (7) The pooled prevalence using a meta-analysis of the random effects model was 24.73% (95%CI, 19.98-30.19), with high heterogeneity (I2 = 100%). (8) The prevalence of sleep disturbances decreased with high education (OR, 0.83; 95%CI, [0.69-0.99]; I2 = 79%), while it increased with low income (OR, 1.26; 95%CI, [1.12-1.42]; I2 = 59%), unemployment (OR, 2.84; 95%CI, [2.14-3.76]; I2 = 0%), and being a housewife (OR, 1.72; 95%CI, [1.19-2.48]; I2 = 55%). DISCUSSION: This meta-analysis shows that lower SES (education, income, and work) was associated with sleep disturbances in Latin America. Therefore, sleep disturbance management should be addressed with a multidimensional approach, and a significant investment in targeted public health programs to reduce sleep disparities and support research should be made by the government before the situation becomes uncontrollable.

Validation of a Moroccan Arabic Version of the Tinnitus Handicap Inventory (THI-M).

OBJECTIVE: Cultural adaptation of the tinnitus handicap inventory questionnaire to the Moroccan dialect version. METHOD: We conducted a prospective study over a 3 years period (January 2017-January 2020) in the Otolaryngology Department of Casablanca University hospital. Translation was produced by a forward-backward procedure with analysis of the psychometric properties of the Moroccan version of the tinnitus handicap inventory. RESULTS: The final Moroccan version of Tinnitus Handicap Inventory (THI) was given to 83 otosclerosis patients suffering from tinnitus. They filled the questionnaire twice before surgery and 1 year after surgery.The item-total correlations are all statistically significant (p < 0.001) and vary between 0.279 (item 15) and 0.817 (item 12).The internal consistency of the Moroccan version of THI, assessed through Cronbach's α, was found to be excellent at 0.953. The interclass correlation showed an excellent reliability for all subscales (0.999-1).THI scores decreased significantly from baseline to 1-year postoperative follow-up on all subscale scores, indicating clinical improvement. CONCLUSION: The Moroccan version of THI has a good reliability comparable with translations in other languages and the original version. It is a valid tool to assess tinnitus improvement after otosclerosis surgery.

Recurrent pterygo-palatal angiofibroma with intracranial extension: case report.

We report the case of a patient with recurrent pterygo-palatal angiofibroma and its treatment. A 21-year-old male patient had a long history of recurrent epistaxis with progressive nasal obstruction. He was diagnosed with an angiofibroma centered in the right pterygo-palatine fossa. Initially, he underwent surgical excision with removal of the entire tumor. The evolution was clinically good with no signs of recurrence on the cervico-facial scan of control (CT). Nine months after, he presented a reappearance of epistaxis. A cervico-facial MRI was performed and showed a recurrence of the tumor process, which this time was considered inextirpable, hence the decision to opt for radiotherapy with intensity modulated radiation therapy (IMRT). He has improved clinically with a clear reduction in tumor mass on CT scan. This technique represents an interesting alternative to overcome anatomical complexity of the region, cover the tumor and preserve the organs at risk.

[Imatinib in the treatment of chronic myeloid leukemia in Morocco]. / Imatinib dans le traitement de la leucémie myéloide chronique au Maroc.

INTRODUCTION: The treatment of chronic myeloid leukemia (CML) has been revolutionized by the advent of tyrosine kinase inhibitors. The results of the IRIS trial demonstrated the efficacy and long-term safety profile of Imatinib. The objective of our work is to report the results at 15 years of treatment of CML in chronic phase with Imatinib in Morocco. PATIENTS AND METHODS: Retrospective study realized at the hematology unit of CHU d'Ibn-Rochd in Casablanca, from January 2003 to September 2018, including all CML patients in the chronic phase at diagnosis, were treated with Imatinib for a minimum duration of 6 months. RESULTS: In total, 318 patients were collected, the median age was 41.5 years, the sex ratio M/F was 0.7, the Sokal score was high in 56% of cases. The complete hematological response at 3 months was 92%, the complete cytogenetic response at 12 months and the cumulative response were obtained in 43% (29/67) and 55% (153/279) of the cases respectively, the molecular response was evaluated in 125 patients witch 85% were on major molecular response. On a median follow-up of 44 months, the OS and EFS at 10 years were 86% and 59%, respectively. DISCUSSION: Our profile is characterized by a young age of the patients, the female predominance and a high Sokal score. The rate of complete cytogenetic response remains lower compared to what is described, however the survival rates as well as the tolerance were similar to those of the literature.

The effects of Ramadan fasting during pregnancy on fetal development: a general review.

BACKGROUND: From a religious point of view, Ramadan fasting (RF) is not mandatory during pregnancy. However, some pregnant women insist to fast. Does this choice affect fetal development? AIM: The objective of this general review was to determine the impact of RF on fetal development. METHODS: The search was conducted via the following databases PubMed, Scopus, Web of Sciences and Google Scholar from January 1st 2009 to December 31th 2018, using the following query: (« Ramadan « OR « Ramadan month « OR « fasting «) AND (« fetal development « OR « fetal growth « OR « fetal programming «) AND (pregnanc* OR gestat* OR pregnant wom*n). Articles published in English or French were included, and comparative studies on the impact of RF on fetal development in the group of pregnant women who fasted and the group who did not fast, regardless of the stage of gestation. RESULTS: Ten studies met the research criteria and all were case-control ones. Six studies were conducted in Turkey, two in Egypt, one in Iran and one in Pakistan. The RF coincided with the summer period in 8 studies. An obstetrical ultrasound with Doppler was performed on 1390 pregnant women at the beginning and end of Ramadan. Significant decreases in cephalic perimeter, biparietal diameter and femoral length were noted in a single study. A change in the amniotic fluid index was observed in two studies. CONCLUSION: The RF practiced by healthy pregnant women has no negative impact on fetal development.

Bibliometric profil of medical publication at Faculty of Medicine of Casablanca (2008-2017).

AIM: To measure productivity in scientific publications of teachers of the Faculty of Medicine and Pharmacy of Casablanca (FMPC). METHODS: This is a descriptive bibliometric study of the publications of the FMPC, indexed in the Medline and Scopus databases, between 2008 and 2017. Articles of physicians affiliated to the FMPC or its university hospital center were included in this study. RESULTS: With 1041 articles, the average scientific productivity of the FMPC was 38 articles / 100 teachers-year. These articles were published in 244 journals of which 18% in Pan African Medical Journal and 67% in French. In 58% of the articles, the type was "case reports". Dermatology and Genetics were the most prolific medical disciplines with 122 and 76 articles respectively. In surgery, Oto-Rhino-Laryngology and Gynecology-Obstetrics ranked first, with respectively 75 and 60 articles. The impact factor of the journals that published the articles of the FMPC ranged from 0.05 to 26.56 and was less than two in 84% of the cases. National and international scientific collaboration was 2.6% and 6.4% respectively. CONCLUSION: The publication at the FMPC was largely unproductive in English-language journals with a high impact factor. Training in scientific medical writing would be a priority for faculty development and institutional visibility of the FMPC.
