Effectiveness of Pulmonary Rehabilitation in Patients with COPD

Background: Pulmonary rehabilitation (PR) is beneficial for patients with COPD, with improvement in exercise capacity and health-related quality of life. Despite these overall benefits, the responses to PR vary significantly among different individuals. It is not clear if PR is beneficial for patients with COPD and normal exercise capacity. Although it is believed that longer pulmonary rehabilitation programs can provide better results, most of the evidence comes from short-term programs. Objective: The objective of this analysis was to determine the effectiveness of respiratory services provided in the hospital or community by respiratory therapists (RTs) in reducing health care utilization and improving patient outcomes. The aim was to evaluate the outcomes of a comprehensive pulmonary rehabilitation (PR) in chronic obstructive pulmonary disease. Methodology: All 65 Pakistani patients who met the inclusion criteria with ages between 40 to 65 years, including both male and female, with mild to severe COPD were enrolled in the study on the basis of convenient sampling. Informed consent was taken from each patient starting about the study and their rights to withdraw from study. A demographics detail (name, age, sex) was noted along with the necessary medical history. A questionnaire was made to see the effects of pulmonary rehabilitation in patients with COPD. All necessary tests were performed to evaluate the patient betterment completely. Results: The mean FEV1 in the subjects was 1.29 ± 0.47 L/min, 64.8 ± 23.0% of predicted. Clinically there is a little effect on CXR pattern, FEV1 and FEV1/FVC after pulmonary rehabilitation. But overall quality of life improved after pulmonary rehabilitation. Mainly improvement occurs in peak expiratory flow rate, BORG dyspnea scale, 6 mint walk test distance (meters) and Oxygen saturation after rehabilitation. Conclusion: These results showed that patients with COPD had benefited from a comprehensive PR program in an out-patient setting regardless of disease severity. Exercise training can result in significant improvement in health-related quality of life, exercise capacity, respiratory muscle strength, and exertional dyspnea in subjects with COPD and normal exercise capacity

COMPARATIVE EFFICACY OF HYPERTONIC SALINE AND NORMAL SALINE SOLUTIONS IN EXPERIMENTALLY INDUCED ENDOTOXIC SHOCK IN DOGS

This study was contemplated to determine the comparative beneficial effects of hypertonic saline solution and sterile saline solution in induced endotoxic shock in dogs. For this purpose, 12 healthy Mongrel dogs were randomly divided into two equal groups (A and B). All the animals were induced endotoxaemia by slow intravenous administration of Escherichia coli endotoxins 0111:B4. Group A was treated with normal saline solution @ 90 ml/kg BW, while group B was given hypertonic saline solution @ 4 ml/kg BW, followed by normal saline solution @ 10 ml/kg BW. Different parameters were observed for evaluation of these fluids including clinical and haematological parameters, serum electrolytes, mean arterial pressure, and blood gases at different time intervals up to 24 hours post treatments. After infusion of respective fluids, all parameters returned to baseline values in both the groups but group B showed better results than group A except bicarbonates, which better recovered in group A. Thus, it was concluded that a small-volume of hypertonic saline solution could be effectively used in reversing the endotoxaemia. Moreover, it provides a rapid and inexpensive resuscitation from endotoxic shock

Factors associated with financial security, food security and quality of daily lives of residents in Nigeria during the first wave of the COVID-19 pandemic

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic

Abstract Number ‐ 223: Spontaneous Revascularization of Completely Occluded Internal Carotid Artery: Case Report

Introduction Occlusion of the internal carotid artery (ICA), caused by atherosclerotic thrombosis, arterial embolism, or dissection, is associated with high morbidity and mortality of acute stroke. Commonly, these lesions are managed with aggressive medical treatment due to their chronic and usually irreversible nature. Spontaneous recanalization of the occluded ICA has been described in rare instances. Methods We present a report here on three cases with spontaneous recanalization of complete occluded carotid arteries. Results Our first patient was a 62‐year‐old male with a history of hypertension, who presented with transient left eye vision loss. CT angiography of the head and neck (CTA HN) demonstrated left ICA complete occlusion while the left middle cerebral artery (MCA) and anterior cerebral arteries (ACA) were patent. He was treated with apixaban. At the two‐month follow‐up, the repeat CTA HN demonstrated complete recanalization of the left ICA. The etiology of the occlusion remained cryptogenic. Our second patient was a 71‐year‐old male with a prior history of right carotid endarterectomy, peripheral vascular disease, coronary artery disease, hypertension, and dyslipidemia, who presented with acute right MCA stroke. Work‐up with CTA HN demonstrated right ICA complete occlusion. He was treated medically with aspirin and clopidogrel. Six months later, he presented with a two‐week history of intermittent confusion and left‐sided weakness. His MRI brain was negative foracute stroke. Interestingly, CTA HN demonstrated that the right ICA had complete recanalization. The cause of carotid thrombosis remained cryptogenic. Our third patient was a 46‐year‐old female with a history of hypertension, hyperlipidemia, remote low‐speed vehicle collision, and cervical spine chiropractic treatment (the last neck manipulation was about two years prior), presenting with sudden onset dizziness, right‐sided neck pain, and left homonymous hemianopia. Brain MRI showed acute right posterior cerebral artery (PCA) stroke. CTA HN revealed occlusion of the right ICA with a flare‐up appearance suggestive of a carotid dissection. She also had a right fetal PCA. She was treated medically with rivaroxaban. Four months later, a follow‐up MR angiogramof the neck showed a fully revascularized right ICA. Her hypercoagulable workup revealed that she had a rare form of breast cancer. Conclusions Although ICA occlusion is generally considered chronic and irreversible, our case series suggests that the lesion can have spontaneous recanalization with medical treatment. Further studies of characterizing carotid occlusion to predict recanalization are warranted

Socio-economic factors associated with post-traumatic stress symptoms among adolescents and young people during the first wave of the COVID-19 pandemic

Abstract This study assessed the association between sociodemographic factors and post-traumatic stress symptoms (PTSS) among 18–24-year-olds during the first wave of the COVID-19 pandemic. This was a secondary analysis of data from 4508 individuals collected through an online survey conducted between June and January 2021. PTSS was measured as a dependent variable using the checklist for post-traumatic stress disorder in civilians. Age, birth sex, sexual, level of education, access to emotional and social support, and emotional distress were the independent variables. A multivariate logistic regression analysis was conducted to determine the associations between the dependent and independent variables while controlling for the country related confounding variables. Females (AOR:2.023), sexual minority individuals (AOR:1.868), those who did not disclose their sexual identify (AOR:1.476), those with poor access to emotional and social support (AOR:4.699) and individuals with no formal education (AOR:13.908), and only primary level education (AOR:4.521) had higher odds of PTSS. The study highlights the multifaceted nature of PTSS during the pandemic and suggests the importance of promoting access of young people, especially females, sexual minority individuals and those with low educational status, to emotional/social support to mitigate the probability of PTSS, especially among sexual minority individuals

A multi-country survey on access to healthcare and treatment services among individuals with critical medical care needs during the first wave of the pandemic

Background Healthcare services were significantly interrupted during the early phase of the COVID-19 pandemic. The aim of the present study was to determine the associations between sociodemographic factors and healthcare access during the first wave of the COVID-19 pandemic among individuals with critical care needs.MethodsThis was a secondary analysis of the data of 5,156 participants recruited from 152 countries during the first wave of the COVID-19 pandemic. The dependent variables were self-reported difficulty of access to health care, challenges with obtaining medication, and the use of alternative medical services. The independent variables were age at last birthday; sex at birth, level of education, employment status and the macro-social vulnerability status. The confounding variable was the country income level. Three multivariable logistic regression analyses were conducted to determine the associations between the dependent variables and the independent variables after adjusting for the confounder.ResultsDifficulty accessing health care services and obtaining medications was experienced by 1922 (37.3%) and 3746 (72.7%) participants respectively. Also, 1433 (27.8%) used alternative medical care. Retirees (AOR:1.59), unemployed (AOR:1.198), people living with HIV (AOR:2.36) and at increased risk of COVID-19 (AOR:2.10), people who used drugs (AOR:1.83) and transacted sex (AOR:1.971) had significantly higher odds for reporting difficulty with access to health care. Males (AOR:1.23), respondents with secondary level of education (AOR:1.39), retirees (AOR:2.19), unemployed (AOR:1.47), people living with HIV (AOR:2.46), people who used drugs (AOR:1.79), transacted sex (AOR:2.71) and those who might be (AOR: 1.66) and were at (AOR: 2.3) increased risk of severe COVID-19 had significantly higher odds for reporting difficulty with access to medications. People who used drugs (AOR:2.093) transacted sex (AOR:1.639), who might be (AOR: 1.211) and were at (AOR: 1.511) increased risk of severe COVID-19, and who had difficulty accessing usual healthcare (AOR: 9.047) and obtaining medications (AOR:2.16) had significantly higher odds of reporting alternative medical care use. People living with HIV (AOR:0.562) had significantly lower odds of using alternative medical care.ConclusionWe identified populations who had challenges with access to healthcare and obtaining medications used alternative medical care except for people living with HIV. Priority attention should be given to alternative medical care use during future health pandemics.Peer reviewe
