Pathological and Immunohistochemical Assessment of Aging of the Abdominal Skin Treated with Carboxytherapy: A Randomized, Split-body Trial.

Background: Skin aging as a continuous and irreversible process is mainly the result of alterations of function and structure of the dermis. Among the modalities used for treating skin aging, carboxytherapy has been introduced as a safe minimally-invasive method for rejuvenation, reparation, and reconditioning of the skin.

Objective: We assessed the efficacy of carboxytherapy for the treatment of intrinsic skin aging through pathological and immunohistochemical (IHC) investigations.

Effects of Body Position on Cochlear Function in Infants: An Otoacoustic Emission Study.

Background: Otoacoustic Emission (OAE) is frequently recorded in various body positions for infants. However, little is available about whether these deviations will produce non-pathological effects on the clinical results. The current study assessed body position's effect on infants' inner ear function.

Assessment of efficacy of carboxytherapy in management of skin aging through evaluation of gene expression profile: a 2-split randomized clinical trial.

Skin aging is a continuous and irreversible process which results in impairment of the skin role as barrier against all aggressive exogenous factors. It mainly manifests by photoaging, laxity, sagging, wrinkling, and xerosis. Carboxytherapy is considered as a safe, minimally invasive modality used for rejuvenation, restoration, and recondition of the skin.

Unlabelled: We sought to evaluate the effetc of metformin on body mass index (BMI) and metabolic parameters in HIV-positive patients. We performed a comprehensive search through five major indexing databases, using keywords ("metformin" OR "dimethylguanylguanidine" OR "biguanide" ORGlucophage") AND ("HIV" OR "human immunodeficiency virus" OR "AIDS" OR "Acquired immunodeficiency syndrome"), and all possible combinations until January 15, 2021. We measured standardized mean differences (SMD) and 95% confidence intervals (CI) for each outcome.

Background: The aim of this study is to evaluate the sex differential effect in the COVID-19 mortality by different age groups and polymerase chain reaction (PCR) test results.

Research Design: In a multicenter cross-sectional study from 55 hospitals in Tehran, Iran, patients were categorized as positive, negative, and suspected cases.

Results: A total of 25,481 cases (14,791 males) were included in the study with a mortality rate of 12.

A Survey of Psychological Distress Among the Community in the COVID-19 Epidemic: A Cross-Sectional Study.

Aim The ongoing COVID-19 outbreak has not only had an impact on physical health but also on psychological health. The aim of this study was to measure the prevalence and severity of psychological distress in the community due to the COVID-19 pandemic. Methods This cross-sectional survey was conducted in February and March 2020 in Tehran, Iran.

Coronavirus (COVID-19)-Associated Psychological Distress Among Medical Students in Iran.

Aim The COVID-19 was declared a pandemic in early 2020 and is associated with high public anxiety all over the world. The healthcare community is at the highest risk of infection and thereby prone to most distress. The aim of this study was to explore and evaluate the degree of depression, anxiety, and stress levels among medical college students during the COVID-19 epidemic in Iran.

Survey of Immediate Psychological Distress Levels Among Healthcare Workers in the COVID-19 Epidemic: A Cross-Sectional Study.

Aim: The outbreak of COVID-19 has laid unprecedented psychological stress on healthcare workers (HCWs). We aimed to assess the immediate psychological impact of COVID-19 epidemic on the HCWs at Baqiyatallah Hospital in Tehran, Iran.

Material And Methods: We conducted a cross-sectional survey of HCWs using questionnaires in February and March 2020 in Baqiyatallah Hospital, Tehran.

Depression, Anxiety, and Stress Among Patients with COVID-19: A Cross-Sectional Study.

Aim: Patients with confirmed COVID-19 infection can develop several psychological consequences. Epidemiological data on mental health and psychological disorder inpatients infected with COVID-19 pneumonia are not available in Iranian patients. The purpose of this study was to evaluate the anxiety, stress, and depression of patients with COVID-19.

Vestibular rehabilitation therapy in combination with transcranial direct current stimulation (tDCS) for treatment of chronic vestibular dysfunction in the elderly: a double-blind randomized controlled trial.

Introduction: Dizziness and imbalance are common dysfunctions in the elderly. Vestibular rehabilitation therapy is an effective method to alleviate chronic dizziness in patients with vestibular dysfunction. Transcranial direct current stimulation has reportedly improved balance function in patients with vestibular dysfunction.

Influence of Cochlear Implantation on Balance Function in Pediatrics.

Background And Objective: Patients with profound Sensorineural Hearing Loss (SNHL) are susceptible to vestibular disturbances following Cochlear Implant (CI) surgery. This study aimed to evaluate vestibular dysfunctions following unilateral CI in the congenitally deaf children.

Methods: This was a cross-sectional study conducted on 24 children (mean age: 10.

Perceptual organization of sequential stimuli in cochlear implant listeners: A temporal processing approach.

Objective: Cochlear Implant (CI) users often suffer difficulties in perceiving speech in noisy environments that could be attributed to reduced Auditory Stream Segregation (ASS) ability. ASS is the process used to separate a complex sound into different perceptual streams. The evidence that CI listeners routinely experience stream segregation skill is limited and equivocal.

Early Diagnosis of Hearing Loss in Patients Under Methadone Maintenance Treatment.

Methadone maintenance treatment (MMT) as the most effective treatment for opioid addictions could induce both reversible and permanent hearing loss. Therefore, early detection of methadone-induced hearing loss is necessary to prevent irreversible cochlear damage. The present study aims to identify the early onset of hearing loss in patients who underwent MMT and to compare them with the age and gender matched normal hearing peers.

Background And Aims: COPD is an irreversible or persistent airflow obstruction, which affects up to 600 million people globally. The primary purpose of this systematic review was to explore the COPD-based alteration in the auditory system function by conducting a quantitative analysis of presently published data.

Materials And Methods: We systematically searched seven diverse electronic databases and manual searching of references to identify relevant studies.

Effect of conductive hearing loss on central auditory function.

Introduction: It has been demonstrated that long-term Conductive Hearing Loss (CHL) may influence the precise detection of the temporal features of acoustic signals or Auditory Temporal Processing (ATP). It can be argued that ATP may be the underlying component of many central auditory processing capabilities such as speech comprehension or sound localization. Little is known about the consequences of CHL on temporal aspects of central auditory processing.

A comparison of auditory perception in hearing-impaired and normal-hearing listeners: an auditory scene analysis study.

Background: Auditory scene analysis (ASA) is the process by which the auditory system separates individual sounds in natural-world situations. ASA is a key function of auditory system, and contributes to speech discrimination in noisy backgrounds. It is known that sensorineural hearing loss (SNHL) detrimentally affects auditory function in complex environments, but relatively few studies have focused on the influence of SNHL on higher level processes which are likely involved in auditory perception in different situations.

Vestibular rehabilitation outcomes in the elderly with chronic vestibular dysfunction.

Background: Chronic vestibular dysfunction is a frustrating problem in the elderly and can have a tremendous impact on their life, but only a few studies are available. Vestibular rehabilitation therapy (VRT) is an important therapeutic option for the neuro-otologist in treating patients with significant balance deficits.

Objectives: The purpose of this study was to assess the effect of vestibular rehabilitation on dizziness in elderly patients with chronic vestibular dysfunction.
