A population-based and symptom-based COVID-19 prevalence survey.

The current study aimed to determine the community-based COVID-19 prevalence and compare the symptom-based and test-based prevalence rates in the Omicron peak (February 20 to March 20, 2022) to assess community involvement and provide effective healthcare. This cross-sectional and population-based study examined the prevalence of COVID-19 from February 20 to March 20, 2022, in the city of Khomein in Markazi Province (located in central Iran) through random cluster sampling. The period prevalence of recurrent Omicron symptoms was 37.

Evaluate the Case Fatality Rate (CFR) and Basic Reproductive Rate (R-naught) of COVID-19.

Introduction: SARS-CoV-2 primarily affects a person's respiratory system and leads to the spread of pathogenicity in the person and therefore this study evaluated the Case Fatality Rate (CFR) and Basic Reproductive Rate (R-naught) of COVID-19.

Method: This cross-sectional descriptive study was performed on all people with COVID-19 from the first date of admission of positive PCR patients with SARS-CoV-2 until September 21, 2020, in the area of Markazi Province in Khomein, Iran. Information on the records of definitively discharged and deceased patients due to COVID-19 (having positive PCR) was extracted from 20/2/2020 to 21/9/2020, and Case Fatality Rate (CFR) and Basic Reproductive Rate (R-naught) of COVID-19 were evaluated.

Physical and mental growth and development in children with congenital hypothyroidism: a case-control study.

Introduction: The clinical complications of congenital hypothyroidism such as brain disorders are very subtle and are not recognizable in infancy period. They are recognizable when it is too late for treatment or prevention. General screening of newborns is effective in diagnosing congenital hypothyroidism and initiating initial treatment.

Investigation of the Epidemiological Situation and the Incidence of Covid 19 Disease in an Area of Markazi Province in Iran Country.

Introduction: Coronavirus is an emerging virus that has caused many casualties. Therefore, the purpose of this descriptive study is to investigate the epidemiological situation of coronavirus in Khomein city in the province of Markazi in Iran.

Method: This cross-sectional descriptive study was performed on all people with coronavirus disease from the first date of admission of positive PCR of patients with coronavirus until 21 September 2020.

Cancer in Iran 2008 to 2025: Recent incidence trends and short-term predictions of the future burden.

Policymakers require estimates of the future number of cancer patients in order to allocate finite resources to cancer prevention, treatment and palliative care. We examine recent cancer incidence trends in Iran and present predicted incidence rates and new cases for the entire country for the year 2025. We developed a method for approximating population-based incidence from the pathology-based data series available nationally for the years 2008 to 2013, and augmented this with data from the Iranian National Population-based Cancer Registry (INPCR) for the years 2014 to 2016.

The Frequency of High-Risk Behaviors Among Iranian College Students Using Indirect Methods: Network Scale-Up and Crosswise Model.

Background: Since the direct questions usually underestimate the frequency of sensitive behaviors, indirect methods can be used to estimate the frequency of some risky behaviors such as illicit drug use, sexual behaviors especially where these behaviors are highly stigmatized.

Objectives: In the current study, we indirectly estimated the prevalence of some risky behaviors among college students using two indirect methods: network scale-up (NSU) and crosswise model (CM).

Patients And Methods: Having recruited 563 students from one of Iran's major medical universities, the prevalence of opium and drug use, alcohol consumption, relationships with the opposite sex (RWOS),and extra/pre-marital sex (EPMS) were estimated using two indirect methods.
