Background:

Institutional quarantine centres were set up in all districts in Kerala as a novel strategy in the fight against novel COVID-19 virus. These were meant for returnees from affected areas, for whom home quarantine was not possible due to lack of facilities. This research aims to evaluate facilities and services of Institutional quarantine centres in Thiruvananthapuram district, Kerala state and to study profile of persons under quarantine in these centres.

Methods:

A cross-sectional study was conducted to evaluate institutional quarantine centres established in Thiruvananthapuram district of Kerala in April 2020. Evaluation was done using a checklist based on standard operating procedures for functioning of centres issued by Health department. Inspection of facilities and registers was done. Details of a subset of inmates were collected by telephonic interviews using a semi-structured questionnaire.

Results:

Two (0.41%) inmates in the centre turned positive on testing while in quarantine. Both of them were foreign returnees and were asymptomatic. There was not a single case of transmission of infection between inmates or to staff and volunteers. The adherence to infection control practices was satisfactory in all centres. One third of inmates were from listed highly affected countries and were mandatorily quarantined.

Conclusion:

Institutional quarantine centres were functioning effectively to provide quarantine facilities for high-risk individuals and thereby controlling the spread of COVID-19. Selection of facilities, staffing pattern and day to day functioning of these centres is a model which can be replicated at other COVID-19 affected areas.

Authors: Chandy Sujith J. , Ranjalkar Jaya , Chandy Sheeba S.
Published: January 2021

COVID-19 has affected the daily activities of people across the globe. The effects of the pandemic have not just been medical, but also societal and economical. The responses of government and the public have varied in different countries. Measures have ranged from improving hygiene, information dissemination, and social distancing to more radical measures such as social isolation, quarantine and lockdown. The disease and human responses have had consequences on the way we live, work, eat and rest. Life and livelihoods have been affected. This article highlights how the response to the pandemic has affected various aspects of healthcare and ethical dilemmas this has raised. As the pandemic progresses, awareness and evaluation of the unintended consequences of the pandemic and responses on our health and healthcare systems are needed. Discussing these points and being aware of the ethical issues may help countries and policy makers plan suitable strategies to mitigate these collateral effects, especially as the pandemic continues. It is hoped that this article will support healthcare workers, especially those in primary and secondary healthcare, as they overcome various challenges to treat patients with existing and prior diseases, and encourage them to advocate for robust and sustainable healthcare systems for public health. This would then help effectively combat future epidemics. Most importantly, it can mitigate the adverse collateral effects on healthcare that the public are experiencing and the treatment dilemmas that family and primary care physicians are facing.
Non-invasive saliva-based screening of high-risk Human Papilloma Virus 16 and 18 in healthy young adults and creating awareness about its vaccination
Authors: Kumari Bandana , Ali Asgar , Sharma Abhay K. , Gehlot Aishwarya , Sharma Sadhana
Published: January 2021

Context:

Human Papilloma Virus (HPV) has not only been linked with cervical cancer but also a key player in other types including oral cancer. Vaccine against HPV has shown promising outcomes in protection against cervical cancer. It is suggested that the same vaccine may be a safeguard against oral cancer as well. Since prevalence of oral cancer is on rise because of various reasons besides high-risk sexual behavior, its prevention becomes equally important.

Aim:

Study aimed at screening saliva samples of healthy young adults to detect the presence of HPV with an intention to increase awareness regarding HPV and its vaccination.

Settings and Design:

The study was executed in the department of Biochemistry, AIIMS, Patna. This cross-sectional study included 100 consented healthy undergraduate medical and nursing students.

Methods and Material:

We isolated DNA from all saliva samples, amplified using multiplex PCR and gel electrophoresed to screen HPV 16 and 18. Feedback about the study in creating awareness regarding HPV and its vaccine was conducted using three-point Likert scale.

Statistical analysis:

The collected responses were entered in Microsoft excel. The results were expressed in frequency and percentages.

Results:

All saliva samples screened were found negative for HPV 16 and 18 DNA. Responses from feedback showed improved knowledge and awareness about the HPV and its vaccine among the participants.

Conclusion:

Even all the saliva samples tested were found negative for HPV DNA, the screening of high-risk HPV in saliva of young medical and nursing students generated curiosity among them to know more about HPV and its vaccine. This exercise may have helped in increasing the acceptance of HPV vaccine and the awareness of getting it at their ideal age to be benefited with dual protection, from oral and cervical (in case of females) cancers lifelong.

Published: January 2021

The COVID-19 pandemic is a lifetime experience of 'Living within a pandemic' for the vast majority world over. Public health principles based on equity should be at the core of world's response to it. Service professionals such as taxi/cab drivers are no exception. It is a challenge for them to establish mechanisms for making taxi services safer with regards to SARS COV2 spread, and thereby regain the confidence of stakeholders in this necessary public service. This requires a comprehensive planning taking into account the socio-economic stresses, psychosomatic health and other determinants, and yet being able to adapt and innovate for safer services. These considerations and decisions have to be based on available as well as emerging research evidence about this infection both in the lab and in the community. Targeted safety interventions that translate and apply research findings hold promise. While the course of the pandemic remains uncertain, life must find a 'new normal' and people need to get back to the business of regular living. The purpose of this review is to study the various risks to the stakeholders in taxi/cab services, and draft strategies for mitigating these risks from a theoretical and practical perspective.
MuLBSTA score in COVID-19 pneumonia and prediction of 14-day mortality risk
Authors: Preetam Mukul , Anurag Aditya
Published: January 2021

Background:

The infectious agent which has caused the COVID-19 pandemic is a coronavirus named SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). On one end of the spectrum, a patient suffering from COVID-19 may be asymptomatic or have mild symptoms, while on the other end of the spectrum, a patient may develop numerous life-threatening complications. The way a host responds to infection by SARS-CoV-2 depends on various host factors like hypertension, old age, etc., The MuLBSTA scoring system takes into account various clinical and laboratory parameters and tries to predict the mortality risk for a patient. Besides, the validation of MuLBSTA score for mortality because of COVID-19 has not been extensively studied in an Indian set-up. This study is aimed at finding the association between the MuLBSTA score and the 14-day mortality risk because of COVID-19 in Indian population.

Materials and Methods:

This study included 122 patients who were receiving treatment for SARS-CoV-2 infection at a tertiary hospital in Ranchi, Jharkhand. The disease severity (as per the ICMR guidelines), the MuLBSTA score, and the disease outcome of all patients were noted and analyzed in this study.

Results:

A strong association was seen between a MuLBSTA score of ≥12 and the 14-day mortality risk in COVID-19 patients.

Conclusion:

The MuLBSTA scoring system is an easy to calculate model, which predicts the 14-day mortality risk because of SARS-CoV-2 infection. This may help the primary care physicians in stratifying and referring the patients who have a higher chance of developing severe complications.

Published: January 2021

Introduction:

There has been a new challenge to the already existing threat of tuberculosis (TB) and that is drug resistance TB (DR-TB). The causal relationships between mental disorders and TB are complicated and relatively unexplored. For this reason a qualitative study was done on DR-TB patients attending R G Kar Medical College.

Materials and Methods:

The study population consisted of the patients who are registered for the DR-TB regimen are followed up four times with General Health Questionnaire (GHQ). Those scoring poorly were sent for expert evaluation by psychologist, who counselled them, and followed them up after in-depth interviews. These records of in-depth interview were analysed as qualitative research inputs.

Results:

In our study out of 165 patients, (4.8%) needed interventions. The domains emerging from the study are worried about future and as well as family, disbelief about the diagnosis, embarrassment regarding the diagnosis, fear of death, blaming fate for the disease, stigma, suicidal ideation.

Conclusion:

This study finds out the important domains of psychogical problems among the patients and also advocates a psychologist to remain at DR-TB centres.
Predictive factors for acquiring HCV infection in the population residing in high endemic, resource-limited settings
Authors: Khan Samreen , Shah Sabeen , Ashraf Hiba
Published: January 2021

Background:

In a country like Pakistan, a high prevalence of HCV persists due to a lack of awareness among the masses and the absence of adequate medical facilities in less privileged areas. Therefore, this study aimed to develop a risk-based screening tool based on the identification of predictive factors for HCV in the adult population in Karachi, Pakistan, which can later be validated for implementation.

Methodology:

A case-control study design was adopted and data was collected through an interview-based questionnaire from among 284 patients visiting the Family Medicine Department at The Indus Hospital, Karachi on whom the anti-HCV antibody test was conducted. Received data was then entered and analyzed using Statistical Package for the Social Sciences (SPSS) version 21.0.

Result:

Analysis indicated that in the entire cohort, marital status, employment status, history of being operated on in the past, family history of HCV infection, and body piercing were the factors significantly associated with positive HCV antibody. Results thus achieved show that the anti-HCV-positive rate was higher in ever married, employed, having had surgery, and family history of HCV infection (aOR: 2.42, 3.5, 2.04 and 2.5, P = 0.043, 0.002, 0.011 and 0.005, respectively).

Conclusions:

It is concluded that future research may be conducted enrolling the heterogeneous population to further probe the HCV burden and incidence in our society to initiate educational purposes. This goal can be achieved through commercial advertisements and free public lectures for disease prevention and better health awareness among the masses and the curers.

Authors: Patel Ishani S. , Dongara Ashish R. , Mungala Bhavdeep M. , Chapla Apurva , Phatak Ajay G. , Nimbalkar Somashekhar M.
Published: January 2021

Background:

Every year, globally 570,000 women are diagnosed with cervical cancer, out of which around 311,000 die. India contributes to about 132,000 new cases and 74,000 deaths yearly. One of the major risk factors for cervical cancer is infection with some types of human papillomavirus (HPV). This is both preventable (by vaccination) and detectable early (routine screening programs).

Objective:

The objective of this study is to assess the knowledge and attitude in medical and paramedical students about cervical cancer and HPV vaccination.

Material and Methods:

A cross-sectional survey was conducted, using predesigned and validated questionnaire. It was segregated into three parts: Q1—demographic details, Q2a—questions assessing knowledge, Q2b—questions assessing attitude. Our target population was female students (18–25 years) studying in medical, nursing, and physiotherapy colleges. Descriptive statistics of data was analyzed using SPSS 16.0.

Results:

We had 73% response rate. Most participants belonged to upper middle and upper socioeconomic class, were pursuing MBBS, resided in villages, had educated parents, and had good health-care-seeking behavior. School education, television, and printed advertisements appeared to be underutilized. Around 50% of the participant had received chickenpox and typhoid vaccine, but only 8% had received HPV vaccine. The mean knowledge score was 5.19 ± 2.24, with 0.00 minimum and 11.0 maximum, out of a maximum possible score of 17. Only, place of residence appeared to effect the knowledge score.

Conclusion:

The study shows the dismal knowledge levels about HPV amongst students. Participants were interested in seeking knowledge; consider HPV vaccination provided they were provided with sufficient knowledge.

COVID-19 and Violence against doctors – Why a law is needed?
Authors: Kuppuswamy Gayathri , Warrier Uma
Published: January 2021

Today, when India is reeling under the COVID-19 epidemic, a new epidemic disease (Amendment) Ordinance has been brought out with regard to protection of the health care staff, which is a big welcome step to the medical fraternity. A much-needed step. The assaults on doctors have been happening in hospitals in India for a long time. This review article traces the journey of the Prevention of the Doctors Violence Act and suggests a way forward with regard to violence on the doctors and why there must be a permanent solution for the same. Methodology is based on a detailed study across a range of published literature in journals, articles, and other online sources. An extensive review has been undertaken of these articles based on an explanatory approach. The review provided insight into the current status of violence against doctors. Most of the initiatives on prevention of violence against doctors mentioned in the studies are mainly directed towards patient-doctor relationship, lack of infrastructure, strenuous working environment, and societal obligations. Study findings revealed that there was less emphasis on the current legal measures available and its implementation. This article highlights the critical aspect of protection of the health care workforce and also shares recommendations to enhance the protection of doctors at their workplace by sharing the current state-level legal measures available and advocates the impelling need for central legislation. These recommendations have been suggested as a combined effort of the medical fraternity, media, and the academic community.

The Nairobi Summit and Reproductive Justice: Unmet Needs for People with Infertility
Authors: Dierickx Susan , De Proost Michiel , Huang Anny Yuanfei , Ceesay Sainey , Clarke Ed , Balen Julie
Published: January 2021

The Nairobi Summit, held in November 2019 and convened by the United Nations Fund for Population Activities, claims to have represented “all nations and peoples, and all segments” of society during its high-level conference. The overall aim of the summit was to mobilize political will and financial commitments that are urgently needed to “finally and fully” implement the 1994 International Conference on Population and Development (ICPD) Program of Action. Despite the recommendation by ICPD to incorporate infertility care in reproductive health services, the new Nairobi Statement largely neglects the topic of infertility. This is particularly troublesome as infertility is a global health problem affecting between 52.6 and 72.4 million couples worldwide, with a high prevalence in low- and middle-income settings. For many people around the world, infertility constitutes an emotional, social, and financial burden, yet appropriate services directed toward preventing and addressing infertility are often inaccessible, unaffordable, or nonexistent. With the impetus of a wider reproductive justice community, we call for the integration of infertility into global reproductive health research and practice, urging policy makers, practitioners, researchers, activists, and funders worldwide to bring focused attention to addressing challenges posed by a lack of safe, effective, and dignified fertility management among those in need.

Treatment failure to intralesional sodium stibogluconate (IL-SSG) is a health challenge for cutaneous leishmaniasis (CL) in Sri Lanka. A randomized controlled proof of principle clinical trial, with two arms (viz., radio frequency–induced heat therapy [RFHT] by a ThermoMed™ device (Model 1.8, Thermosurgery Technologies, Inc., Phoenix, AZ) and thermotherapy by a handheld exothermic crystallization thermotherapy for CL [HECT-CL] device) was conducted on 40 CL treatment failures to IL-SSG, from three hospitals in Tangalle, Hambantota, and Anuradhapura, from January 2017 to January 2018, followed up for 180 days post-thermotherapy with a final follow-up in February 2020. Intention-to-treat cure rates were calculated at day 90 (initial cure rate) and at day 180 (final cure rate) posttreatment. Radio frequency–induced heat therapy group: the initial cure rate was 100% (20/20) and the final cure rate was 95% (19/20), with one patient relapsing. The HECT-CL group: both the initial and final cure rates were 80% (16/20), with no relapses and one excluded from the trial. In February 2020 (1.6–3 years posttreatment), 27 traceable patients (RFHT = 16, HECT-CL = 11) remained healed. Second-degree burns were observed with RFHT in 65% (13/20), with HECT-CL in 15% (3/20), which completely resolved subsequently. The cure rates between the two treatment groups were comparable (P = 0.15). Radio frequency–induced heat therapy consumed less time and required only a single hospital visit. Handheld exothermic crystallization thermotherapy for CL is potentially usable at community settings with both being less costly than IL-SSG. This study is the first proof that thermotherapy is an efficacious and safe treatment for CL patients in Sri Lanka, complicated by treatment failure to IL-SSG.

Published: January 2021

In this study, the performances of two types of Radiation Energy Balance Systems (REBS) net radiometers, a domed (model Q-7.1) and domeless (model NR-LITE) against a reference, four-component net radiometer (model NR01), are evaluated during the conduct of Nigeria  Micrometeorological Experiment (NIMEX) held between May 27 and June 12, 2013 at a tropical location in Ile-Ife, Nigeria. During the daytime, net radiation measurements made by NR-LITE and Q-7.1 showed good agreements with NR01, with coefficient of determination for both > 0.90. The values of the mean and standard deviation for daytime net radiation as  measured by NR01, NR-LITE and Q-7.1 were 257.7 ± 174.7 W m2 , 179.6 ± 129.3 W m2 and 240.6 ± 153.1 W m2 , respectively. At nighttime, NR-LITE net radiometer responded to longwave radiation better than Q-7.1. Adjustments made by linear regression of NR-LITE and Q-7.1 datasets with NR01 produced better fit. Though costs of the two REBS type net radiometers are comparatively the same, Q-7.1 performed better than NRLITE. However, for long-term operation, the Q-7.1 type requires periodic (every 2-3 months) changing of the plastic domes due to ageing and cracking, unlike the NR-LITE. So, the NR-LITE is a preferred option to be adopted by the Weather Services in West African countries for routine measurements of net radiation because it does not require periodic changing of the plastic domes.

Keywords: Net radiation; REBS net radiometers; 4-component net radiometer; tropical location.
Self-consistent estimates of emission factors of carboncontaining pollutants from a typical gas flare
Authors: Fawole O.G. , Cai X.-M. , Nikolova I. , MacKenzie A.R.
Published: January 2021

This study proposes an approach for estimating the emission of soot, carbon monoxide (CO) and carbondioxide (CO ) from a typical gas flare. The estimations depend on the quantity and varying composition of the 2 natural gas, flame dynamics (represented by the fire Froude number, Fr ) and the equivalence ratio, f, of the fuel- f air mixture. Soot emission estimates are presented as a function of fire Froude number for gases used in labbased  test in order to validate the scheme and for two real-world fuel gas compositions. The mass-weighted carbon-hydrogen ratio (C:H) of the fuel gas compositions are 0.25 and 0.29 which are two extreme cases in terms of density. The soot yield of the lab-based test case was scaled up to estimate the soot yield of a full scale flare using the Richardson number as the scaling parameter. When all other variables are held constant at values characteristics of real-world flares, a difference of 16 % in the fuel-gas density, as indicated by the carbonhydrogen ratio, results in an increase of the emission factors (EF) of soot, CO and CO by factors of ~3, ~1.4 2 3 and ~1.7, measured in g/m , respectively. For both fuel gas compositions, the ratio of EF to EF at the fuel- soot CO lean region f < 1) is higher. The ratio lies in the range 0.031 – 0.13 and 0.0012 – 0.0055 for the fuel-lean (f < 1) and fuel-rich (f > 1) regions, respectively. The approach proposed and results obtained may be adopted to generate emissions inventories of emission species associated with gas flaring on regional and global scales.

Authors: Nwabueze J.C. , Sogbanmu T.O. , Ugwumba A.A.A.
Published: January 2021

The evaluation of biomarkers in resident fisheries of aquatic ecosystems is important for risk assessment of such ecosystems. In this study, surface water and sediment physicochemical characteristics, macrobenthic invertebrate and fish species diversity and oxidative stress of dominant fish were evaluated at an anthropogenic-impacted site (Iddo) as well as a reference site (after the Third Mainland Bridge) of the Lagos lagoon, Nigeria, over a period of three (3) months. Surface water analysis result showed that the Total dissolved solids (TDS) (5.54±2.85 mg/L), Salinity (5.09±2.56 o/oo), Conductivity (6.51±4.54 µS/cm), Nitrates (4.70±1.49 mg/L), Phosphates (3.03±0.60 mg/L), Biochemical oxygen demand (BOD) (18.62±3.77 mg/L) and Chemical oxygen demand (COD) (463.44±65.83 mg/L) were significantly higher at the test site compared to the reference site. The COD of the sediment were significantly higher (p<0.05) at the test site compared to the reference while the other sediment physicochemical parameters except pH were higher at the test site compared to the reference site. Macrobenthic invertebrate species diversity were slightly higher (1.70) at the reference site compared to the test site (1.66) while species richness were higher at the test site (1.43) compared to the reference site (1.26). Fish species diversity (1.95) and richness (1.79) were higher at the test site compared to the reference site. Dominant fish species at the test and reference sites were Ethmalosa fimbriata (Bonga shad) and Sarotherodon melanotheron (Blackchin Tilapia) respectively. There were increased levels of antioxidant enzymes and biomolecules- glutathione S-transferase (GST), superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and malondialdehyde (MDA) in the gills and liver of E. fimbriata indicative of oxidative stress. Further studies on biomarkers at lower levels of biological organisation are recommended for holistic evaluations and evidence-based intervention if necessary. This will support the achievement of the United Nations Sustainable Development Goal 14 (life below water).

Published: January 2021

Polylactic acid (PLA) microfibrous composite scaffolds having hydroxy apatite (HA) particles in the fibers were prepared by electrospinning of PLA and wet chemical hydrothermal reaction HA with average diameter of 8.13 µm. The fibers were compressed in mould into bulk scaffolds. Microscopy characterizations confirmed integration of the crystalline HA and PLA fibers in both before and after compression. The morphology, porosity of scaffolds were examined by scanning electron microscope (SEM). The HA content were observed by SEM and determined by Thermogravimetry Analysis (TGA). Agglomeration gradually appeared and increased on the fiber surface along with the increase of HA concentration. The fiber diameter also increased with the HA concentration. Mechanical property of scaffold was examined by compressional strength test. The scaffold prepare for bone substitute implant application with suitable mechanical performance and morphology.
One-Class Classifiers: A Review and Analysis of Suitability in the Context of Mobile-Masquerader Detection
Authors: Mazhelis Oleksiy
Published: January 2021

One-class classifiers employing for training only the data from one class are justified when the data from other classes is difficult to obtain. In particular, their use is justified in mobile-masquerader detection, where user characteristics are classified as belonging to the legitimate user class or to the impostor class, and where collecting the data originated from impostors is problematic. This paper systematically reviews various one-class classification methods, and analyses their suitability in the context of mobile-masquerader detection. For each classification method, its sensitivity to the errors in the training set, computational requirements, and other characteristics are considered. After that, for each category of features used in masquerader detection, suitable classifiers are identified.
Análisis descriptivo de sentencias sobre trata de personas: Un estudio de casos judiciales entre 2011 y 2019
Authors: Salat Paisal Marc
Published: January 2021

El trabajo presenta los resultados de un estudio cuantitativo con una muestra censal (N=221) de las sentencias dictadas por las Audiencias Provinciales sobre trata de seres humanos existentes en la base de datos CENDOJ durante los años 2011 a 2019. Se pretende conocer la prevalencia y la tipología de los casos que llegan a los tribunales con el objetivo de comparar estos con los datos ofrecidos por los estudios de prevalencia fenomenológica. Entre los resultados, destaca que el 99% de supuestos son por trata internacional con fines de explotación sexual (85%). Los acusados son mayormente extranjeros (92%) y hay un número importante de mujeres. Las víctimas son mujeres (90%) y extranjeras (98,6%). El 33% de las sentencias terminan en absolución. La principal conclusión es que los resultados muestran una sobrerrepresentación de casos de trata para explotación sexual en los que la víctima procede de terminados países extranjeros.
An Occupational Therapy Approach to Education for Foster Parents
Authors:   , Judd Alexandra
Published: January 2021

The focus of this project is to enhance current programming for foster parent pre-licensure education courses in San Diego, California. This capstone project focused on the preferred learning styles of foster parents and utilized adult learning theories to create suggestions to enhance the current pre-licensure class curriculum. Data collected during verbal interviews with foster parents helped guide the suggestions to enhance the current curriculum. Utilizing specific occupational therapy group strategies, occupational therapists can help enhance education for foster parents by increasing the saliency of the learning material. The increased saliency facilitates a deeper understanding of the material and increases the retention of knowledge amongst participants. The capstone project will explore how occupational therapists can help enhance the current pre-licensure curriculum for foster parents to be more inclusive of different learning styles.

In Algeria, camel breeding participates in the national milk production. However, this breeding faces significant health problems, including mammary pathologies. This disease is a major public health threat, due to the existence of human pathogens in milk. Several species are associated with this mastitis. Unlike cow’s milk, goat and camel milk are most often consumed in the fresh raw state, thus escaping any official control. The present study aimed to determine the nature and frequency of mastitis, and the nature and frequency of the responsible bacteria in each type of mastitis in southern Algeria. A total of 62 camels were subjected to clinical examination and screening for subclinical mastitis and the presence of Brucella using the California Mastitis Test (CMT) and ring test, respectively. CMT positive samples were then further subjected to bacteriological analysis. Clinical and subclinical mastitis were present with frequencies of 4.44% and 95.55%, respectively. Bacteriological analysis isolated a total of 73 samples of 45 seeds. Staphylococci were most commonly isolated, with a frequency of 63.01%. Among these, Staphylococcus aureus were at the top of the list, with 35.61%, while Staphylococcus SCN (coagulase negative staphylococci) represented only 27.39%. Streptococci were the second most isolated group, with 28.77%. Gram-positive bacilli were in third place, accounting for 6.85% of all isolates. Gram- negative bacilli (enterobacteria) were isolated with a frequency of 1.36%. Brucella was present with a frequency of 4.44%. Finally, an extended study on a larger sample of camels is required in the future.

Published: January 2021

Objetivo: Sistematizar conhecimentos sobre as implicações da pandemia do COVID-19 nos hábitos alimentares. Método: Este estudo constitui uma revisão integrativa desenvolvida a partir da seleção sistemática da literatura científica voltada para os efeitos da pandemia do COVID-19 na alimentação. A coleta de dados foi realizada no período de 11 de agosto a 19 de setembro de 2020, onde a busca bibliográfica dos artigos se deu nas bases de dados Scielo, PubMed, BVS, Medline e LILACS. Resultados e Discussão: Foram selecionados 31 artigos para leitura e fichamento, por estarem dentro da temática proposta. As restrições provocadas pelo isolamento resultaram em consequências na saúde mental, no estilo de vida e hábitos alimentares, redução no consumo de alimentos in natura e ganho de peso. Em contrapartida, notou-se padrões opostos entre as pesquisas, onde houve uma maior ingestão de vegetais/frutas e menor consumo de junk food, redução no consumo de bebidas alcoólicas e comportamentos alimentares mais saudáveis quando comparados aos hábitos anteriores. Considerações Finais: Neste contexto, vê-se a necessidade de novos estudos que avaliem a qualidade nutricional da alimentação durante e pós pandemia e a inserção de ações e programas intensivos que atuem como forma de promover suporte para uma dieta saudável e variada.

Authors: Kartal Mustafa Tevfik
Published: January 2021

This study examines the reaction of local currency oil prices to the COVID-19 pandemic using Turkish daily data (July 25, 2019 to October 30, 2020). A multivariate adaptive regression splines model is employed that considers foreign exchange (USD-TRY), credit default swap spread, global uncertainty, and global volatility as control variables. The findings show that: (i) the volatility index influences oil prices most regardless of the sample size; and (ii) the COVID-19 pandemic affects the importance of effective variables on the local currency oil prices in Turkey.

Administration of several chemotherapeutic agents is associated with a significant risk of neurotoxicity. Neurologic adverse reactions are frequently observed after ifosfamide, which metabolites may cause acute ifosfamide-induced encephalopathy (IIE). There is no standard management in this clinical setting. Herein we report a case of 28 year old male with a B-cell lymphoma unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma. The patient developed a severe IIE with catatonia, as well as fecal and urinary incontinence during combined systemic ifosfamide-based chemotherapy. The infusion was interrupted; hydration and forced diuresis were implemented. Drugs with known sedative effect on the central nervous system were eliminated. Nevertheless, no improvement was observed. At this point a decision was made to administer methylene blue (MB). Two doses were infused at intervals of 6 hours with fast improvement and elimination of IIE symptoms on the second day after MB infusion. Noteworthy, no toxicity attributable to MB was observed. Described treatment was based on previous case reports and small retrospective series and obtained results fully confirmed the conclusions of these publications.
