Introduction: Impact of assisted reproductive treatment (ART) techniques on the child's mental development is the focus of numerous studies. Whereas several studies have found potential negative effects on ART children's psychosocial health, others recognized that the data on the cognitive and psychosocial development of ART children are comforting. Objectives: Here, we aim to state the current findings concerning psychological outcomes in children conceived by ART. Methods: Using as key words "assisted reproductive" and as filter "meta-analysis", we comprehensively reviewed the scientific literature through new meta-analysis during the five last-years resuming the main conclusions of these studies to define principal through psychological conditions in children conceived by diverse ART techniques and approaches. Results: Our review showed that since 1978, the date of the first birth using in vitro fertilization technology (IVF), more than 10 million children are conceived by ART. Our research revealed 441 meta-analysis. After a comprehensive analysis of abstracts, only four meta-analysis were selected. Chronologically from 2019 to 2023, the first studies showed that the risk of intellectual disability and autism spectrum diseases (ASD) were higher in intra-cytoplasmic sperm injection (ICSI) children compared to conventional IVF children. The differences in the risk of neurodevelopmental disorders in children born after frozen and fresh embryo transfers were not significant. Analysis of potential cofounder effects such as multiple and preterm birth having a significant correlation with neurodevelopmental disorders suggested that ART is unlikely to cause negative impacts on children's neurodevelopment. The findings of the most recent meta-analysis showed that the use of ART did not associate with the risk of ASD, Conclusions: Given the multitude of factors modulating ART, from the indication and parental background to the type of used technique and approach, the results of the studies that investigated the association between ART and neurodevelopmental outcomes remain yet contradictory.

Introduction: In females, congenital adrenal hyperplasia (CAH), a spectrum of inherited genetic conditions related to the disruption of adrenal steroidogenesis, is among the most common conditions leading to inappropriate virilization. For adolescent and adult women, progression of hirsutism may have many psychological concerns. Objectives: To explore the psychological distress of a young Tunisian woman who sought medical help and psychological support at a late stage, after suffering from genital ambiguity and severe virilization. Methods: Harboring phenotypic male transformation at puberty, our patient attended genetic counselling for cytogenetics assessment. Clinical, biological, psychological and genetic explorations were thus carried out. Results: A 17-year-old female was born from first-degree consanguineous parents, and had healthy siblings (a sister and three brothers). After a single menstrual episode at puberty, she developed amenorrhea and an unexpected progressive virilization, including hirsutism with an inappropriate beard that she had to shave every day and a male voice. Clinical examination revealed a male morphotype with an enlarged clitoris that resemble a penis, male-type pubic hair, underdeveloped of breasts, abnormal cutaneous hyperpigmentation, and a short stature. Pelvic ultrasound revealed a small uterus, but with no visualized gonads. Genetic exploration showed a female 46,XX karyotype and the absence of Y chromosome sequences. Diagnosis of a non-classic CAH was confirmed. Psychological assessment found that the psychological development of the sexual identity corresponded to the assignment of the female sex. A severe psychological suffering due to the non-acceptance of her virile appearance impaired the quality of her daily personal and social life. Stigmata of a depressive syndrome were also revealed. Conclusions: Particular attention to the psychological assessment of patients with CAH is recommended, as changes in physical appearance have a detrimental impact on psychological and mental well-being.

Background: The outbreak of coronavirus disease (COVID-19) continues to constitute an international public health concern. Few data are available on the duration and prognostic factors of the disease. We aimed to study the recovery time among a Tunisian cohort of COVID-19 confirmed patients and identify the prognostic factors., Methods: A retrospective, nationwide study was conducted from March 2 to May 8, 2020, recruiting all patients who were diagnosed with COVID-19, by RT-PCR methods, in Tunisia. Data were collected via phone call interview. Kaplan-Meir Methods and Cox proportional hazards regression models were, respectively, used to study the recovery time and estimate its prognostic factors., Results: One thousand and thirty patients with COVID-19 (aged 43.2 ± 18.2 years, 526 female (51.1%)) were enrolled. Among them 141 (14.8%) were healthcare professionals. Out of 173 patients (17.8%) admitted to the hospital, 47 were admitted in an intensive care unit. Among 827 patients who didn't require specialized care, 55.5% were self-isolated at home, while the rest were in specialized centers. Six hundred and two patients were symptomatic. A total of 634 (61.6%) patients have recovered and 45 (4.4%) patients died. The median duration of illness was estimated to be 31 days (95% CI: [29-32]). Older age (HR = 0.66, CI:[0.46-0.96], P = 0.031) and symptoms (HR = 0.61, CI:[0.43-0.81], P = 0.021) were independently associated with a delay in recovery time. Being a healthcare professional (HR = 1.52, CI: [1.10-2.08], P = 0.011) and patients in home isolation compared to isolation centers (HR = 2.99, CI: [1.85-4.83], P < 10¯ 3 ) were independently associated with faster recovery time., Conclusion: The duration of illness was estimated to be 1 month. However, this long estimated duration of illness may not equate to infectiousness. A particular attention must to be paid to elderly and symptomatic patients with closer monitoring.

Background: Describing transmission dynamics of the outbreak and impact of intervention measures are critical to planning responses to future outbreaks and providing timely information to guide policy makers decision. We estimate serial interval (SI) and temporal reproduction number (R t ) of SARS-CoV-2 in Tunisia., Methods: We collected data of investigations and contact tracing between March 1, 2020 and May 5, 2020 as well as illness onset data during the period February 29-May 5, 2020 from National Observatory of New and Emerging Diseases of Tunisia. Maximum likelihood (ML) approach is used to estimate dynamics of R t ., Results: Four hundred ninety-one of infector-infectee pairs were involved, with 14.46% reported pre-symptomatic transmission. SI follows Gamma distribution with mean 5.30 days [95% Confidence Interval (CI) 4.66-5.95] and standard deviation 0.26 [95% CI 0.23-0.30]. Also, we estimated large changes in R t in response to the combined lockdown interventions. The R t moves from 3.18 [95% Credible Interval (CrI) 2.73-3.69] to 1.77 [95% CrI 1.49-2.08] with curfew prevention measure, and under the epidemic threshold (0.89 [95% CrI 0.84-0.94]) by national lockdown measure., Conclusions: Overall, our findings highlight contribution of interventions to interrupt transmission of SARS-CoV-2 in Tunisia.

Rhizopus oryzae lipase (ROL) was immobilized by adsorption onto oxidized cellulose fibers and regenerated films. The maximum adsorption level increases with the raise in the amount of carboxylic groups on cellulose surface confirming that adsorption is being governed mainly by electrostatic interaction between the enzyme and the substrate. This hypothesis was further confirmed by zeta-potential measurements showing a decrease in the zeta-potential of the fibers after enzyme adsorption. XPS analysis showed an intensification of the N 1s peak attesting the presence of the enzyme on the surface. The effect of temperature, pH and solvent polarity on the immobilized enzyme activity and stability was investigated. The catalytic esterification of oleic acid with n-butanol has been carried on using hexane as an organic solvent. A high conversion yield was obtained (about 80%) at 37 degrees C with a molar ratio of oleic acid to butanol 1:1 and 150IU immobilized lipase. The adsorption achieved two successive cycles with the same efficiency, and started to lose its activity during the third cycle.
