The novel coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has instigated a global pandemic as a formidable and highly contagious infectious disease. Although the respiratory system remains the most frequently affected organ, several case reports have revealed that the complications are not merely limited to the respiratory system, and neurotropic and neuroinvasive properties have also been observed, leading to neurological diseases. In the present paper, it was intended to review the possible neuroinvasive routes of SARS-CoV-2 and its mechanisms that may cause neurological damage. Additionally, the neurological manifestations of COVID-19 across the globe were discussed with emphasis on Iran, while highlighting the impact of SARS-CoV-2 on the central and peripheral nervous systems.Anti-CD4 IgG autoantibodies have been implicated in CD4+ T cell reconstitution failure, leaving people with HIV (PWH) at heightened risk of HIV-associated comorbidities, such as neurocognitive impairment. Seventeen PWH on stable anti-retroviral therapy (ART) and 10 HIV seronegative controls had plasma anti-CD4 IgG antibodies measured by enzyme-linked immunosorbent assay. Neuropsychological (NP) tests assessed cognitive performance, and brain volumes were measured by structural magnetic resonance imaging. Anti-CD4 IgG levels were elevated (p = 0.04) in PWH compared with controls. Anti-CD4 IgG correlated with global NP z-scores (rho = - 0.51, p = 0.04). A relationship was observed between anti-CD4 IgG and putamen (β = - 0.39, p = 0.02), pallidum (β = - 0.38, p = 0.03), and amygdala (β = - 0.42, p = 0.05) regional brain volumes. The results of this study suggest the existence of an antibody-mediated relationship with neurocognitive impairment and brain abnormalities in an HIV-infected population.
Intellectual disability (ID) is a heterogeneous disorder affecting 1-3% of the population. Elucidation of monogenic variants for ID is a current challenge. These variants can be better demonstrated in consanguineous affected families.

The study was designed to find the genetic variants of ID in consanguineous families.

We analyzed five unrelated consanguineous Pakistani families affected with ID using whole exome sequencing (WES). Data was analyzed using different bioinformatics tools and software.

We mapped four variants including three novels in four different ID known genes. Each variant is found in a different family, co-segregating with a recessive pattern of inheritance. The novel variants found are; c. 2_4del (p.?) mapped in ROS1 and c. 718G>A (p.Gly240Arg) in GRM1. Another novel causative variant, c.2673del (p.Gly892Aspfs*17) identified in COL18A1 in a recessive form, a gene reported for Knobloch syndrome that manifests ID along with typical retinal abnormalities, and this phenotype was confirmed on reverse phenotyping. BAY-218 nmr A mutation c.2134C>T (p.Arg712*) in TRAPPC9 has been found first time in the homozygous recessive form in our enrolled three affected siblings while it was previously reported in compound heterozygous form in a Caucasian descent. While fifth family remained unsolved.

These mutations in four different genes with a recessive inheritance would be a contribution to the disease variant database of this devastating disorder.

Congenital adrenal hyperplasia involves a series of autosomal recessive disorders where adrenal steroidogenesis is affected. We present a detailed molecular investigation of 13 newborns affected from the severe form of congenital adrenal hyperplasia related to 21-hydroxylase deficiency.

All patients were diagnosed with classical congenital adrenal hyperplasia in the neonatal period due to adrenal crisis and/or ambiguous genitalia presentation. None of the infants was identified through a congenital adrenal hyperplasia newborn screening program. A molecular analysis of the CYP21A2 gene and a familiar segregation analysis were performed.

Adrenal crisis was the most severe manifestation in the male salt-wasting newborns while all female patients presented with atypical genitalia. Newborns were correctly genotyped and no genotype-phenotype divergences were found. Two novel severe genotypes, not previously reported, were identified. The novel CYP21A2 frameshift mutations (c.793delG and c.297dupG) were added to the other 45 variants recently reported in the literature, leading to a total count of 279 pathogenic variants affecting the gene.

We have successfully genotyped 13 infants diagnosed with classical congenital adrenal hyperplasia after birth. Our molecular approach led to the identification of two novel frameshift CYP21A2 pathogenic variants related to the salt-wasting form of congenital adrenal hyperplasia.

Health fluctuations even within a single day are typical in multiple sclerosis (MS), but are not captured by widely used questionnaires like the EQ-5D-5L. This exploratory study aimed to develop an ambulatory assessment (AA) version of the EQ-5D-5L (EQ-5D-AA) where patients rate their health on mobile phones multiple times per day over several days, and to assess its feasibility and face validity.

An initial EQ-5D-AA version was based on two patient focus groups. It was then tested and continuously developed in an iterative process patients completed it over several days, followed by debriefing interviews. Findings were used to refine the EQ-5D-AA, with the resulting version being tested by the subsequent wave of patients until participants declared no need for changes anymore. Before and after the AA period, participants completed the standard paper-based EQ-5D-5L asking about 'today'.

Focus group participants reported that their impairments often fluctuated between and within days. They regarded an AA with three assessments per day over seven days most appropriate; assessment should be retrospective to the previous assessment, but not all items should be assessed at each time point.
