Discharge of Confirmed COVID-19 Patients Based on WHO or Regional Criteria? A Cohort Study

BACKGROUND

Increasing the number of COVID-19 patients raises concerns about the capacity of the health care system. This issue emphasizes reducing the admission rate and expediting patient discharge.

OBJECTIVE

This study aimed to develop a discharge protocol for COVID-19 patients based on the existing capacity of the healthcare system and to assess its post-discharge outcomes.

METHODS

This is a multicenter cohort study. All COVID-19 patients referred to selected medical centers in Qom, Iran, from Feb. 19 to Apr. 19, 2020, were target populations. Eligible patients were classified into a) the criterion group and b) the non-criterion group. Patients were followed up daily for 14 days after discharge by phone, and the required data was gathered and recorded in follow-up form. Univariate (chi-square and t-tests) and multivariate multiple (multivariate probit regression) analysis were used.

RESULTS

A total of 2775 patients were included in the study (1440 people in the criterion group and 1335 in the non-criterion group). Based on multivariate probit regression, death was statistically associated with discharge outside our criteria (p<0.001), rising age (p<0.001), and being male (p=0.019), and readmission were associated with discharge outside our criteria (p<0.001), rising age (p=0.009), and having the history of underlying diseases (p=0.003). Furthermore, remission had statistically significant associations with discharge based on our criteria (p<0.001), decreasing age (p=0.001), and lack of a history of underlying diseases (p<0.001).

CONCLUSION

Mortality and readmission were significantly lower according to our discharge criteria. Our designed criteria apply to less developed and developing countries due to the limited capacity and resources available in the health care system.

A Thematic Analysis of Dimensions of Spiritual Care

BACKGROUND

An overview of spiritual care studies can help reveal the dimensions of spiritual care and summarize the findings of available studies. Thus, we designed the present study based on existing studies to explain the dimensions of spiritual care.

MATERIALS AND METHODS

In this thematic analysis, we gathered the related articles published in Persian and English in the last 8 years (2013-2021) with the help of the keywords of Care, Support, Spirituality, Religion, Treatment, Hospice, and Palliative, and searching in electronic databases, including PubMed, Scopus, Web Of Sciences, Magiran, Islamic Science Citation (ISC), and Scientific Information Database (SID). We accurately studied 79 articles that met the inclusion criteria, and then the spiritual care components were extracted and coded, and finally, the codes were categorized as themes and sub-theme.

RESULTS

Thematic analysis of available studies revealed that the dimensions (theme) of spiritual care include: spiritual and religious assessment, developing a structure for providing spiritual care, establishing effective and supportive communication with the patient, training the patient, answering his questions, encouraging, maintaining, and improving social communications, encouraging the patient to live happily, helping the patient to achieve peace and calmness, supporting for spiritual rituals and activities, supporting and training the patient's family, and supporting the dying patient.

CONCLUSIONS

Spiritual care includes various and numerous dimensions. Considering the widespread dimensions of spiritual care, it seems necessary to design and plan appropriate studies to reveal other spiritual care dimensions from the perspective of patients and care providers in different cultures.

Comparing the sensitivity and specificity of lung CT-scan with RT-PCR for diagnosis of COVID-19

BACKGROUND

The lung is one of the major organs affected by the SARS-CoV-2 virus. Lung CT scan and RT-PCR are the most valuable diagnostic methods in the early diagnosis and management of COVID-19. Due to the possible inconsistency of the false-negative results for the RT-PCR test, in this study, we aimed to evaluate the sensitivity and specificity of lung CT-scan as an accurate diagnostic method of COVID-19.

METHOD

In this cross-sectional study, patients suspected of COVID-19 and referred to Shahid Beheshti Hospital in Qom city from February 26 to April 13, 2020, were enrolled. For a definitive diagnosis of COVID-19, chest CT scan and RT-PCR testing was performed for 644 patients, and both sensitivity and specificity of lung CT scan were evaluated.

RESULTS

According to the findings, and comparing to the RT-PCR test as the standard gold, sensitivity, specificity as well as, positive predictive and negative predictive values of lung CT-scan were found as follow; 94.47% (95% CI:90.73 - 97.02%), 24.71% (95% CI:20.70 - 29.07%), 40.73% (95% CI:36.58 - 44.99%), 89.08% (95% CI: 82.4 - 94.05%), respectively.

CONCLUSION

According to the findings, the lung CT scan has a better diagnostic value than RT-PCR in symptomatic patients who were referred to the hospital for COVID-19 diagnosis. Performing lung CT-scan in patients with negative RT-PCR test should be assessed.

Uncommon cause of respiratory failure due to a bezoar in the hypopharynx: a case report

Background

Trichotillomania and trichophagia cause trichobezoars, which are masses made of hair. The main presentation of this condition is abdominal pain. However, other complications include gastric outlet obstruction, nausea, vomiting, weight loss, malnutrition, hematemesis, diarrhea, and constipation.

Case presentation

A 57-year-old woman with trichotillomania was admitted to the Emergency Department with the chief complaints of dyspnea on exertion, shortness of breath, dysphagia, generalized weakness, and hoarseness. Spiral chest computed tomography (CT) scan did not reveal any parenchymal lesions Pulmonary CT angiography did not reveal pulmonary embolism. The patient was admitted to the Surgery Department for hand fasciotomy due to contrast leakage, and during laryngoscopy, a trichobezoar was detected that was removed with Magill forceps.

Conclusions

Rare cases of trichobezoars can be observed in humans with gastrointestinal and respiratory symptoms. Precise and timely diagnosis are key for the prevention of more invasive diagnostic procedures.

Evaluation of the simvastatin effects in the treatment of pulmonary hypertension (PH)

BACKGROUND

Pulmonary hypertension (PH) is a rare but life-threatening disease characterized by significant increases in pulmonary arterial pressure (PAP) and right ventricular hypertrophy (RVH), therefore early diagnosis and proper treatment of PH is very important. Statins confer cardiovascular benefits beyond the reduction of serum cholesterol through antiproliferative and antiinflammatory mechanisms and induction of endothelial nitric oxide expression. In pneumonectomized rats injected with monocrotaline, simvastatin reversed established pulmonary hypertension and conferred a 100% survival advantage.

OBJECTIVE

The aim of this study was to evaluate the potential effect of simvastatin treatment in patients with pulmonary hypertension (PH).

PATIENTS AND METHODS

In this prospective before-after pilot trial, 19 patients with primary and secondary causes of PH referred to Khorrami Hospital in Qom, Iran were recruited. Patients were treated with simvastatin, beginning at 20 mg/daily for 2 months, then increasing to 40 mg/daily for another 4 months. Echocardiographic Doppler estimates of systolic pulmonary artery pressures (SPAP) were measured for each patient before prescribing simvastatin and at the end of treatment. Also demographic data, history of smoking and heart functional class (NYHA) before and after treatment were recorded.

RESULTS

Out of 19 patients with PH, fifteen were males (78.95%) and four were females (21.1%) with the mean age of 66 (SD=15.28) yr, range between 18 to 83 years. The commonest cause of PH was chronic obstructive pulmonary disease (COPD) in 15 patients (78.9%). Simvastatin significantly ameliorated PH from 74.79 (SD=23.52) mmHg to 67.21 (SD=20.55) mmHg (P<0.001). Whereas, heart functional class changes were not statistically significant (P=0.157).

CONCLUSION

In this study, we demonstrated that simvastatin treatment decreased SPAP in patients with PH. As the pathogenesis of PH involves inappropriate proliferation and constriction of vascular smooth-muscle cells, and deficiencies of endogenous vasodilators such as prostacyclin and endothelial-derived nitric oxide, the antiproliferative, antiinflammatory and antithrombogenic effect of simvastatin seems to be useful. This study has led physicians to believe that simvastatin may be beneficial for the treatment of PH.
