Interventions in Reducing Caesarean Section in the World: A Systematic Review.

Caesarean section without medical indication imposes many problems to families, personnel and medical equipment causing some side effects to pregnant woman and foetus, compared to natural childbirth. The present study aimed to evaluate the interventions in reducing caesarean section in the world. This study was a systematic review using Embase, PubMed, Scopus, Web of Science, Science Direct, Magiran and SID databases and grey literature. All studies conducted during 2000-2018 were reviewed and finally the studies with inclusion and exclusion criteria were selected. A total of 19 studies were selected among 5,559 studies. The interventions conducted for reducing caesarean section included training the specialists and women by using Six Sigma method, changing the guidelines, reviewing the definition of natural childbirth various stages, encouraging the natural childbirth and expanding painless childbirth. All interventions were divided into educational strategy and managerial strategy. The interventions can be implemented to change the behaviour of physicians and attitude of pregnant women in order to reduce caesarean section. In this regard, the authorities are recommended to make more efforts.

Anterior, frontal congenital triangular alopecia, redundancy in therapy without improvement.

Congenital triangular alopecia (CTA) is a benign noncicatricial localized pattern of hair loss with unknown etiology. Although referred to as "congenital," CTA may develop in adulthood. It is believed that many cases of CTA are never diagnosed or are misdiagnosed; causing the incidence to be underestimated. The present study evaluates a case of 20-year-old woman presenting with a single circular to oval area of hair-loss in the mid-frontal region of her scalp. To date, about 170 cases of CTA have been reported and we present the first case in which the alopecic patch is located in the mid-frontal region of the scalp. We present this case not only to challenge the preconceived notion that all CTAs are frontotemporal, but also to inform other practitioners about this rare condition and prevent redundant medical treatment.

Heterologous expression of NoxA confers aerotolerance in Clostridium sporogenes.

Clostridium is a genus of gram-positive obligate anaerobic bacteria. Some species of Clostridium, including Clostridium sporogenes, may be of use in bacteria-mediated cancer therapy. Spores of Clostridium are inert in healthy normoxic tissue but germinate when in the hypoxic regions of solid tumors, causing tumor regression. However, such treatments fail to completely eradicate tumors partly because of higher oxygen levels at the tumor's outer rim. In this study, we demonstrate that a degree of aerotolerance can be introduced to C. sporogenes by transfer of the noxA gene from Clostridium aminovalericum. NoxA is a water-forming NADH oxidase enzyme, and so has no detrimental effect on cell viability. In addition to its potential in cancer treatment, the noxA-expressing strain described here could be used to alleviate challenges related to oxygen sensitivity of C. sporogenes in biomanufacturing.

The frequency of psychiatric disorder co-morbidities in patients with fibromyalgia: A cross-sectional study in Iran.

AIM: This study aimed to investigate psychiatric disorders in Iranian female patients with fibromyalgia (FM). DESIGN: Female patients, newly diagnosed with FM, were interviewed by a psychiatrist for psychiatric assessments during a 2-year period. METHODS: The diagnosis of the psychiatric disorders was based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). RESULTS: In total, 159 patients with the mean age of 42.15 ± 9.89 were recruited in this study. Over 92% of the cases were also diagnosed with at least one type of psychiatric disorder. Sleep disorders (SDs, 90.57%), mood disorders (MDs, 52.83%), personality disorders (PDs, 40.25%) and anxiety disorders (ADs, 16.98%) were the most prevalent diagnoses among these patients. The logistic regression results correspondingly showed that suffering from Cluster-B PDs was associated with a higher prevalence rate of somatic symptom disorders (SSDs), with a p-value of 0.019 and an odds ratio (OR) of 2.7.

COVID-19 Treatment Success After Repeat Courses of Azithromycin: A Report of Three Cases.

BACKGROUND: Azithromycin has been considered as a possible therapeutic agent for COVID-19 patients. However, there is limited data on its efficacy. CASE PRESENTATION: We describe three patients diagnosed with COVID-19 who did not respond to the initial treatment but improved dramatically upon adding azithromycin with a successful outcome. CONCLUSION: We have presented evidence of the potential beneficial effect of the azithromycin in the treatment of patients with COVID-19 in three different clinical settings. More evidence is needed regarding the microbiological data, safety, and efficacy of this medication in the management of COVID-19.

Distinguishing repeated polymerase chain reaction positivity from re-infections in COVID-19.

BACKGROUND: Possibility of reinfection with SARS-CoV-2 changes our view on herd immunity and vaccination and can impact worldwide quarantine policies. We performed real-time polymerase chain reaction (RT-PCR) follow-up studies on recovered patients to assess possible development of reinfections and re-positivity. METHODS: During a 6-month period, 202 PCR-confirmed recovering COVID-19 patients entered this study. Follow-up RT-PCR tests and symptom assessment were performed 1 month after the initial positive results. Patients who tested negative were tested again 1 and 3 months later. The serum IgG and IgM levels were measured in the last follow-up session. RESULTS: In the first two follow-up sessions, 82 patients continued their participation, of which four patients tested positive. In the second follow-up 44 patients participated, three of whom tested positive. None of the patients who tested positive in the first and second follow-up session were symptomatic. In the last session, 32 patients were tested and four patients were positive, three of them were mildly symptomatic and all of them were positive for IgG. CONCLUSIONS: A positive RT-PCR in a recovering patient may represent reinfection. While we did not have the resources to prove reinfection by genetic sequencing of the infective viruses, we believe presence of mild symptoms in the three patients who tested positive over 100 days after becoming asymptomatic, can be diagnosed as reinfection. The immune response developed during the first episode of infection (e.g., IgG or T-cell mediated responses that were not measured in our study) may have abated the symptoms of the reinfection, without providing complete protection.

Isolated severe thrombocytopenia in a patient with COVID-19: A case report.

COVID-19 is known to cause serious respiratory symptoms and involvement of other body systems such as hematopoietic, neurological and the immune system. In this report, we described a case of a COVID-19 patient who presented with no pulmonary involvement but severe thrombocytopenia. She suffered from headache and malaise with no respiratory symptoms, fever or chills. Chest radiological imaging was unremarkable but, the laboratory results showed significant thrombocytopenia associated with relatively decreased lymphocytes. Based on her high-risk work environment, a reverse transcription polymerase chain reaction (RT-PCR) test was performed and SARS-CoV-2 RNA was detected in the nasopharyngeal swab. Complete blood count (CBC) of patient was re-checked during admission and platelet count showed rising trend up to normal levels. A narrow diagnostic approach where only febrile patients with pulmonary symptoms are evaluated for a COVID-19 diagnosis will result in many missed diagnoses; so it is important that physicians are familiar with atypical and rare presentations of COVID-19, such as isolated thrombocytopenia.

Safety and effectiveness of azithromycin in patients with COVID-19: An open-label randomised trial.

As no specific pharmacological treatment has been validated for use in coronavirus disease 2019 (COVID-19), we aimed to assess the effectiveness of azithromycin (AZM) in these patients at a referral centre in Iran. An open-label, randomised controlled trial was conducted on patients with laboratory-confirmed COVID-19. A total of 55 patients in the control group receiving hydroxychloroquine (HCQ) and lopinavir/ritonavir (LPV/r) were compared with 56 patients in the case group who in addition to the same regimen also received AZM. Patients with prior cardiac disease were excluded from the study. Furthermore, patients from the case group were assessed for cardiac arrythmia risk based on the American College of Cardiology (ACC) risk assessment for use of AZM and HCQ. The main outcome measures were vital signs, SpO2 levels, duration of hospitalisation, need for and length of intensive care unit admission, mortality rate and results of 30-day follow-up after discharge. Initially, there was no significant difference between the general conditions and vital signs of the two groups. The SpO2 levels at discharge were significantly higher, the respiratory rate was lower and the duration of admission was shorter in the case group. There was no significant difference in the mortality rate between the two groups. Patients who received AZM in addition to HCQ and LPV/r had a better general condition. HCQ+AZM combination may be beneficial for individuals who are known to have a very low underlying risk for cardiac arrhythmia based on the ACC criteria.
