A viabilidade econômica de modelos de biodigestores para a produção de biogás
Authors: Da Paixão Alcântara Lucas
Published: April 2024

A adoção do biogás não é apenas financeiramente viável, mas também favorável ao meio ambiente como uma tecnologia que ajuda a reduzir as emissões de carbono. A população rural dos países em desenvolvimento precisa urgentemente de biogás para cozimento, iluminação e refrigeração, pois existe uma demanda por biogás nessas comunidades, que advém de uma deficiência energética. Através de uma revisão bibliográfica sistemática, utilizando a base de dados Periódicos CAPES, e por meio da comparação entre os diferentes modelos de digestor existentes, analisando parâmetros financeiros, socioeconômicos e as causas de insucesso da implantação dessas tecnologias, o digestor modelo Tubular se destaca pelos baixos custos e pela facilidade de construção e operação. A elaboração de um projeto com as diretrizes necessárias para construção e operação de um digestor Tubular, aliado ao incentivo de políticas públicas governamentais, são fatores que vão impulsionar a adoção e ampliação de tecnologias renováveis no Brasil. Para a produção de biogás em larga escala destaca-se o modelo CSTR, abreviado do inglês Continuous Stirred Tank Reactor, um reator de tanque de fluxo continuo com agitação, devido aos resultados positivos dos parâmetros determinísticos como o Valor Presente Líquido de R$ 1.888.166,24 e Payback de aproximadamente 3,2 anos. A análise estatística da probabilidade de sucesso da implantação deste tipo de tecnologia reforça ainda mais a possibilidade de ampliação da geração de energia através de fontes alternativas não fosseis. Portanto, a utilização de biodigestores para a produção energética através da queima do biogás é uma grande oportunidade para a diversificação da matriz energética do país.

Published: April 2024

A abóbora cabotiá é um fruto altamente nutritivo, podendo ser utilizada para fabricação de diversos produtos. No entanto, resíduos de casca e semente são desperdiçados em paralelo a gama de nutrientes que possuem. Nesse sentido, a ideia de fabricação de farinhas de casca, semente e polpa de abóbora baseia-se no intuito de enriquecer a dieta do consumidor, através da adição deste produto em industrializados, como por exemplo, o hambúrguer. Assim, é necessário conhecer suas características nutricionais para avaliar a eficácia do processamento e benefícios à saúde do consumidor. Logo, o objetivo deste estudo foi determinar a composição centesimal de farinhas de casca, semente e polpa da abóbora cabotiá e realizar análise sensorial de hambúrgueres incorporados delas. Para isto, inicialmente obteve-se as farinhas e realizou-se análises de umidade, cinzas, lipídios, proteínas, carboidratos e fibras. Posteriormente, as farinhas foram incorporadas em hambúrgueres, os quais foram analisados sensorialmente. Os resultados demonstraram elevado teor de fibras e proteínas nas farinhas e apenas os hambúrgueres adicionados de farinhas de semente e polpa de abóbora cabotiá foram aceitáveis. Portanto, a utilização de resíduos de abóbora cabotiá para fabricação de farinha mostra-se uma alternativa promissora, pois possibilita o aumento de valor nutritivo de produtos industrializados sem afetar a aceitação do mercado consumidor.

A comparative analysis of screening technologies for transfusion-transmitted infectious diseases
Authors: Gupta Vidushi , Meena Seema Kumari , Patidar Gopal Kumar , Hazarika Anjali
Published: April 2024

BACKGROUND AND OBJECTIVES:

Ensuring the safety of blood supply relies on robust screening and donor selection processes. This study assessed the technical performance of automated enzyme-linked immunosorbent assay (ELISA) (EVOLIS, Bio-Rad, France) and electrochemiluminescence immunoassay (ECLIA) (COBAS 6000 e601 and COBAS e411, Roche Diagnostics, Germany) in detecting hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections.

MATERIALS AND METHODS

Retrospective data of transfusion transmissible infections (TTI) screening test results were collected from blood center records, encompassing two phases: January 2020 to May 2020 (phase 1) and March 2021 to April 2021 (phase 2). The sensitivity, specificity, positive predictive value, and negative predictive value of ELISA and ECLIA were calculated. Performance evaluation was conducted using the Youden’s index and the kappa coefficient.

RESULTS:

The study included a total of 824, 755, and 830 donor samples in phase 1 and 1237, 1238, and 1236 donor samples in phase 2 for HIV, HBV, and HCV testing, respectively. High agreement (kappa 0.88, 0.95) existed between ELISA and COBAS e601 for HIV and HBV, with substantial agreement (kappa 0.66) for HCV. Likewise, substantial agreement (kappa 0.66, 0.79, 0.79) was found between ELISA and COBAS e411 for all three parameters HIV, HBV and HCV, respectively. Notably, nearly all false-positive samples detected by ECLIA had low cutoff index values ranging from 1 to 6.5.

CONCLUSION:

The differences in sensitivity and specificity contribute to the discrepancy observed between various serological testing platforms, such as ELISA and ECLIA, for TTI testing. Specifically, low signal/cutoff ratios ≤6.5 obtained with ECLIA are highly indicative of false-positive results.
A rare case of a pharyngeal-cervical- brachial variant of Guillain–Barré syndrome
Authors: Kumari Supriya , Pandey Prashant , Marik Arghyadeep , Mandal Saikat , Gupta Manish , Kumar Praveen
Published: April 2024

Guillain–Barre syndrome (GBS) is an acute, usually symmetrical, and typically de myelinating polyneuropathy, characterized by progressive, ascending paralysis and areflexia, with or without abnormal sensory function. Therapeutic plasma exchange(TPE) was the first therapeutic modality to impact the disease favorably, and several major randomized controlled trials (RCTs) have confirmed its efficacy. Our case is unique, as this critically ill patient admitted in the intensive care unit (ICU), developed a rare form of GBS, the PCB variant of the disease, and was successfully treated with TPE. The diagnosis of PCB can be challenging due to atypical clinical features but its unique presentation does provide sufficient clues to narrow the differential diagnosis, which is helpful in starting empirical therapy at the earliest. Immunomodulation with plasma exchange and IVIG have been found to improve treatment outcomes; 70%–80% of patients usually have a complete recovery. Early diagnosis is very important in the case of the PCB variant of GBS to enable timely intervention. Diagnosis can be made on history and neurological findings alone.

Published: April 2024

Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is associated with a more severe clinical course than acute pancreatitis due to other etiologies. Presently, these patients are managed with dietary restrictions, analgesia, lipid-lowering agents, insulin/heparin dual therapy, and supportive care to prevent organ failure. Apart from these conventional therapies, therapeutic plasma exchange (TPE) is another potential treatment that is being performed as it results in rapid reduction in serum triglycerides and inflammatory cytokines, thus, leading to drastic improvements in clinical and laboratory findings and patient outcomes. Here, we report our experience of using TPE for HTG-AP in our patients.
A case of allogeneic peripheral blood stem cell in a paroxysmal nocturnal hemoglobinuria patient from a COVID-positive donor: Managing the unpreventable

Published: April 2024

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired disease caused by clonal expansion of one or more hematopoietic stem cell lines due to a somatic mutation of the phosphatidylinositol glycan anchor gene. Peripheral blood stem cell (PBSC) harvest is a high-risk procedure and the major concern was regarding the development of COVID infection in the recipient. Herein, we describe an inevitable case of PBSC harvest in a PNH patient who was already started on myeloablation and where the donor became positive 1 day before the harvest. Considering the risk–benefit ratio and the need for elaborate arrangements, the initial plan for bone marrow harvesting was changed to PBSC, and hence, the harvest was performed in a COVID-designated unit. No features of graft versus host disease (GVHD) were observed in the patient. The patient was examined for signs and symptoms of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and there was no evidence of any infection after the procedure. The weekly analysis of the same was done for 1 month after PBSC and the SARS-CoV-2 status remained negative. The authors opine that PBSC from SARS-CoV-2 can be performed safely in some unpreventable situations.
How to define heart failure in 2024 – A critical appraisal
Authors: Singh Alok Kumar
Published: April 2024

Heart failure (HF) is not a single disease, but a rather clinical syndrome of varied etiology, pathogenesis, and different clinical presentation. This makes defining HF more difficult than diseases that have a pathologic gold standard for diagnosis, such as tuberculosis, malaria, and cancer. No textbook definition of HF till date appears to cover the whole spectrum of HF. To fill the gap, all international HF societies came up with a universal definition of HF, which was published in 2021. This definition has been recommended to be used in clinical practice as well as for trial purposes. In this document, I will review the limitations of older textbook definitions of HF and how the newer universal definition of HF has filled the gap in previous textbook definitions.

All patients with two or more comorbidities were contacted for a face-to-face interview and cognitive testing to estimate cognitive function by trained family physicians using St. Louis University Mental State Examination. ANOVA and Chi-square test were used to test for statistical significance. Binary logistic regression was used to show the odds of having cognitive impairment and multimorbidity. All tests were performed at 5% level of significance.

RESULTS:

The study involved 343 individuals; majority (74.1%) aged 60-75 years and were males (67.9%). Hypertension, diabetes, and chronic pain were reported by 56%, 48%, and 44% participants, respectively. Thirty percent participants had 3 or more comorbidities. About 36% had mild neurocognitive disorder and 31.2% had dementia. The results showed that age, gender (female), diabetes, stroke, chronic pain, and multimorbidity were significantly associated with cognitive impairment. In our study, hypertension, coronary artery diseases, depression, and anxiety were not significantly associated with risk of cognitive decline.

CONCLUSION:

Our study found that multimorbidity is significantly associated with cognitive decline. Controlling comorbidities and preventing risk factors in midlife could help in delaying the progression of the disease.

Pigmented fungiform papillae are a rare benign condition. It is commonly considered a diagnosis dilemma as it could be a clinical sign of a serious condition. Our patient was a middle-aged Saudi female presenting with hyperpigmentation along the lateral and anterior aspects of her tongue and was not associated with other cutaneous or mucocutaneous manifestation. Her medical history was significant for iron deficiency anemia, hepatic hemangioma, cervical and lumbar intervertebral disc herniation, and gastroesophageal reflux disease. Upon inspection, she had a longitudinal hyperpigmented tan-brown patch on the lateral aspects of her tongue and pinpoint discoloration evenly distributed on the papillae of the anterior tongue. The examination by mucoscopy revealed a cobblestone appearance along the mentioned distribution. The patient refused to have the biopsy done, but she was reassured about her condition and instructed to visit the clinic if she has any further issues.

Published: April 2024

BACKGROUND:

Healthcare professionals (HCPs) face a variety of work-related stressors that have impact on their mental health and cognitive performance. Work resilience is a psychological resource that helps workers cope with stress and prevents unfavorable psychological impact. The aim of this study was to assess the associations between working as HCPs and cognitive function as well as work resilience.

MATERIALS AND METHODS:

This was a comparative cross-sectional study conducted among HCPs at Suez Canal University Hospital in Ismailia Governorate, Egypt, during April 2023 to August 2023. Two hundred and thirty-five HCPs and 107 administrative employees (Admins) were invited to participate in this study. A self-administered questionnaire was used to obtain sociodemographic and other relavent data. Cognitive function was assessed with the Mini-Mental State Examination test; work resilience was assessed with the Brief Resilience Scale; and psychological distress was measured with the Depression, Anxiety, and Stress Scale - 21-items (DASS-21) scale. Statistical significance was determined by Mann Whitney U-test for continuous variables, and Chi-square test or Fisher’s exact, as appropriate, for categorical variables. Multiple logistic regression models were employed to determine associations between the main outcomes (cognitive impairment and low resilience) and the main covariate (working as HCPs vs. Admins), adjusting for all potential confounders.

RESULTS:

HCPs showed a significantly greater cognitive impairment, less resilience, and DASS-21 than the Admins. The odds of impaired cognitive function in HCPs were significantly higher than the Admins (odds ratio [OR]: 4.45, 95% confidence interval [CI]: 1.27–15.67, P = 0.020), adjusted for all potential covariates. Similarly, the odds of low resilience in HCPs were significantly higher than Admins (OR: 5.81, 95% CI: 2.72–12.44, P < 0.001), adjusted for all potential covariates. However, the adjusted association between impaired cognitive function and low resilience was not statistically significant (OR: 0.55, 95% CI: 0.23–1.33, P = 0.185).

CONCLUSION:

HCPs had significantly impaired cognitive function and low work resilience. Workplace policies and interventions to control depression, stress, and anxiety are required as it is the encouragement of physical activity. Programs that combine positive coping skills training (e.g., relaxation training, positive thinking, and problem solving) with resilience-building interventions (e.g., taking a proactive approach to solving problems, being flexible and adaptive) should be developed, with special attention to HCPs who have a higher sense of self-efficacy.
Comparative evaluation of clinical success of Stainless Steel and Bioflx crowns in primary molar – A 12 month split mouth prospective randomized clinical trial
Authors: Patil Amol Suresh , Jain Mukul , Choubey Shikha , Patil Madhuri , Chunawala Yusuf
Published: April 2024

Purpose:

The purpose of this clinical trial was to assess and compare the clinical outcomes of Bioflx crowns (BFCs) with stainless steel crowns (SSCs) in primary molars (PMs).

Materials and Methods:

This prospective split-mouth randomized controlled clinical trial was conducted between March 2022 and June 2023. Thirty-eight patients (17 females and 21 males) with a mean age of 5.21 years participated in this study. Each child (n = 38) received both SSC and BFC. Clinical and radiographic follow-up was performed at baseline, 3, 6, and 12 months using the modified United States Public Health System scoring criteria to evaluate various parameters.

Results:

At the 3 and 6 months’ follow-up, no significant difference was observed between the two groups. However, at 1-year follow-up, a statistically significant difference (P < 0.05) was evident in the frequency between the two groups for the criteria of crown retention after cementation and anatomic form of the crown, indicating a preference for SSC over prototype 1 BFC.

Conclusion:

The 12-month results indicate that BFC performed similarly to the established SSC for the restoration of PMs providing better esthetics.

Early childhood caries is a major public health issue in India. The primary reason for poor oral health in children is a lack of awareness about the role of primary teeth and the importance of an early dental visit for infants and toddlers. The primary objectives of an early dental visit are to analyze the child’s risk level, provide guidance to parents regarding proper oral hygiene measures, review dietary and eating habits, provide information regarding the infectivity of dental caries, review the risks of traumatic injuries and discuss factors which affect the development of occlusion. Through this paper, we are proposing an “Age One” policy that recognizes dentists, physicians, allied health professionals, community health-care workers, and nongovernmental organizations to work toward a child’s overall health as partners to achieve this goal. The expectation is that this policy will provide guidance to childcare centers, pediatric dentists, other health-care professionals, and legislators regarding oral health activities and the promotion of oral health in infants. The purpose of the policy is to lay the foundation for a lifetime of preventive education and dental care, to help ensure optimal oral health beginning in childhood and continuing through the life course.

Authors: Sharma Prachi R. , Vasavada Dharmesh G. , Phulari Rashmi G. S.
Published: April 2024

Background:

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common genetic disorders affecting approximately 400 million people worldwide. Several recent studies have reported a relationship between G6PD deficiency and the incidence of diabetes.

Objectives:

The aim of the present study was to evaluate and compare levels of G6PD deficiency in diabetes mellitus patients.

Materials and Methods:

G6PD activity and fasting glucose levels were measured in blood samples of 49 diabetic patients and 21 healthy controls.

Results:

G6PD activity was decreased in patients with diabetes mellitus as compared to healthy controls and showed that overall G6PD deficiency was significantly associated with diabetes mellitus as compared to nondiabetics.

Conclusion:

The study concluded that G6PD deficiency is noted in diabetics than in nondiabetics and can be a biomarker of oxidative stress and poor glycemic control in diabetes mellitus.
Quantum dots: The trailblazers of early detection
Authors: Das Pushpanjali , Deshmukh Revati S.
Published: April 2024

Considering the robust awareness of early detection among oral clinicians and patients the increasing imposition of better methods for screening of oral precancerous/cancerous lesions has become imperative. Although histopathology has been considered the indispensable gold standard, it has its pros and cons, as sometimes the diagnosis is compromised with the variabilities subject to the histopathologist under concern. In the realm of oral healthcare, one pioneering trailblazer is making waves, which are ‘quantum dots’. Quantum dots are poised to transform the landscape of oral precancer and cancer screening. These nano-sized semiconductor particles possess extraordinary properties that set them apart from conventional detection methods. Their ability to emit distinct wavelengths of light when excited makes them ideal candidates for early detection. The keywords were pitched in and the research literature from the last 15 years (2008-2022) was extirpated to find out the information that existed, the discrepancies and the void left for upcoming research. Its nature and ingenuity have given rise to a transformative approach that holds the potential to redefine the future of oral healthcare. With each breakthrough, we edge closer to a world where the early detection of oral precancerous/cancerous lesions becomes the norm rather than the exception.
