MERCANTILIZAÇÃO DA LINGUAGEM NA PROMOÇÃO DO TURISMO DE LUXO NA SELVA IRYAPÚ (MISIONES, ARGENTINA): AUTENTICIDADE, DESLOCAMENTOS E RESISTÊNCIA
Authors: Carvalho Simone da Costa
Published: August 2021

RESUMO Vivendo na região da tríplice fronteira Argentina-Brasil-Paraguai, comunidades indígenas da cidade argentina de Puerto Iguazú têm sofrido modificações sociais e territoriais devidas a políticas que resultaram na construção da área turística Selva Iryapú, explorada por redes hoteleiras nacionais e internacionais. Este artigo discute os usos da linguagem na promoção do turismo nessa área, onde elementos da língua e da cultura guaranis são mobilizados para produzir autenticidade e gerar valor agregado simbólico (HELLER; DUCHÊNE, 2012, 2016). Para elaborar este estudo de caso de caráter exploratório, foi realizada pesquisa bibliográfica sobre os guaranis e o turismo na tríplice fronteira; posteriormente, foram efetuadas seleção e análise de textos utilizados na promoção do turismo na área. A análise aponta que tanto os hotéis de luxo quanto as comunidades indígenas mobilizam recursos da língua e da cultura guaranis para gerar valor agregado a produtos e serviços turísticos. No caso dos guaranis, tais usos expressam tanto adesão ao enquadre de lucro quanto estratégias de resistência, de uso desses discursos em prol da preservação de sua língua e cultura. Embora diversos estudos da área apontem a mercantilização da linguagem como possível potencializadora da agentividade dos sujeitos e de geração de renda a grupos minoritários, no presente caso argumentamos que os guaranis, inseridos em uma relação de exploração e alienação capitalista com o empreendimento Selva Iryapú, posicionam-se entre a necessidade e a resistência.
MERCANTILIZACIÓN Y AUTENTICIDAD EN LA FRONTERA URUGUAYO-BRASILEÑA: EL PORTUÑOL EN EL SIGLO XXI
Authors: Albertoni Pablo
Published: August 2021

RESUMEN La situación sociolingüística de la frontera uruguayo-brasileña ha sido objeto de regulación por parte del Estado uruguayo desde finales del siglo XIX. A lo largo del siglo XX, se implementaron distintas políticas públicas, en particular educativas, para erradicar el portugués y su variedad dialectal, el portuñol. Con el impulso de los acuerdos político-lingüísticos asumidos con el MERCOSUR a fines del siglo pasado, el portugués comienza a representarse como símbolo de integración regional, en contradicción con el tradicional discurso prescriptivo. En el siglo XXI, el proyecto liderado por intelectuales y artistas de postular al portuñol como patrimonio cultural inmaterial de Uruguay ante UNESCO, en el contexto de una creciente producción y difusión de arte en portuñol, modifica el estatus de este recurso periférico tradicionalmente estigmatizado y asociado a las clases subordinadas de la sociedad fronteriza. La patrimonialización reconfigura procesos de inclusión y exclusión, al movilizar a los hablantes de la periferia socioeconómica para garantizar la autenticidad del portuñol. Por un lado, las estrategias que los activistas desarrollan para involucrar a los hablantes auténticos dan cuenta de los distintos portuñoles en circulación, en disputa, quiénes les atribuyen valor, quiénes se benefician y quiénes padecen estas dinámicas (cf. HELLER, 2011). Por otro, la consolidación de un nicho de mercado para la producción artística en portuñol tensiona el delicado equilibrio entre autenticidad y mercantilización, requisito para asegurar el valor de lucro de repertorios estigmatizados en la nueva economía globalizada.

Published: August 2021

Resumo As mães de crianças com Síndrome da Zika Congênita (SZC) enfrentam desafios excepcionais no cuidado com seus filhos. Mediante essa realidade, a disponibilidade de suporte social pode funcionar como um importante fator de proteção. Nesse sentido, esse trabalho teve por objetivo avaliar o papel do suporte social informal e formal na saúde mental, autoeficácia parental e satisfação com a vida de mães de crianças com SZC. Participaram desse estudo 69 mães de crianças com SZC (M = 26,4 anos; DP = 6,23), residentes no estado do Ceará, Brasil. Elas responderam a Escala de Satisfação com o Suporte Social, Questionário de Saúde Geral, Escala de Autoeficácia Parental e Escala de Satisfação com a Vida. Os resultados apontam que a maior percepção de suporte social informal prediz significativamente melhores níveis de saúde mental e satisfação com a vida. Ademais, o acesso ao suporte social formal prediz significativamente uma maior percepção de autoeficácia parental. Os resultados observados com as mães de crianças com SZC são coerentes com os relatados em outros estudos, apontando que o suporte social formal e informal apresentam efeitos distintos na saúde mental, autoeficácia parental e satisfação com a vida, cabendo observar que esses efeitos ocorreram mesmo controlando o efeito de variáveis sociodemográficas.

Authors: Vogt Camila de Moura , Fochezatto Adelar , Alvim Augusto Mussi
Published: August 2021

Abstract Cigarette consumption is a worldwide epidemic and its reduction is one of the major public health concerns. In Brazil, although there is a wide literature on smoking cessation it is restricted to experimental studies. Based on data from the 2013 National Health Survey (PNS), this study uses the survival methodology and use population data and consumer’s profile to investigate which characteristics will affect smoking cessation hazard. The results showed that the people who are less likely to quit smoking are older, single men, with low income and fewer education years. They also do not practice physical exercise. The findings of cigarette cessation hazard to Brazilian population are similar of experimental studies with smokers and ex-smokers in country. Therefore, in order to decrease public health spending, Brazilian health policies regarding tobacco cessation could focus on those groups who will likely smoke for a long time.

Published: August 2021

Resumo A autonomia é um processo que nos capacita a compreender e agir sobre nós mesmos e sobre o ambiente. Na adolescência, transformações resultam no desenvolvimento da autonomia. Adolescentes com Síndrome de Down (ASD) têm limitações percepto-cognitivas e poucas oportunidades para aquisição de autonomia. Analisamos o desenvolvimento da autonomia em um grupo terapêutico de Terapia Ocupacional, com díades de ASD e seus principais cuidadores. A análise dos materiais documentais produzidos no processo terapêutico apontou quatro categorias de análise: autopercepção, percepção do outro, vivência compartilhada e mudança de atitude. Os resultados mostram relações simbióticas entre a díade, que dificultam o processo de individuação e limitam as oportunidades para realização das atividades de modo independente. O processo terapêutico baseado na pedagogia freiriana mobilizou de uma consciência ingênua para crítica, acarretando mudanças nas atitudes dos cuidadores em relação à identificação de potenciais e aceitação de limitações próprias e do ASD cuidado. Essa simbiose dificulta o processo de individuação e o acesso a experiências necessárias para o desenvolvimento de autonomia. O processo terapêutico pode modificar as atitudes dos cuidadores e propiciar continuidade do desenvolvimento e autonomia.

Published: August 2021

Resumo A Cogestão é uma das diretrizes da Política Nacional de Humanização (PNH), e vem sendo estudada desde a criação desta política. Apresentamos nesse artigo uma revisão integrativa da literatura nacional sobre Cogestão no contexto da PNH. Foram realizadas pesquisas nas bases de dados BVS, CAPES, Scopus e ProQuest em busca de artigos publicados após a data de implementação da política e que abordassem a Cogestão. Realizamos a análise em profundidade de 36 artigos através de leitura, fichamento e organização dos resultados em duas categorias pré-definidas: aporte teórico e relatos sobre a prática. Sobre o aporte teórico, as publicações analisadas recorrem ao Método da Roda/Apoio Institucional, Ergologia, Hermenêutica, Esquizoanálise, Agir Comunicativo de Habermas e Pedagogia de Paulo Freire, sendo poucas as contribuições originais. Sobre a prática, os autores apresentam a implantação dos dispositivos da Cogestão e abertura de espaços coletivos, os quais têm sido abordados como participativos em si mesmos, havendo pouca reflexão sobre o processo de construção de uma cultura de participação. Assim, apontamos a importância de estudos que deem visibilidade de como se dá, na prática cotidiana das equipes de saúde, a construção relacional da cogestão.

Abstract Low bone health is associated with vitamin D deficiency in older individuals; however, this association is not well established in adults. The aim of the study was to analyze the association between serum concentrations of 25-hydroxyvitamin D and bone health in adults by systematic review and meta-analysis. The search was carried out in the LILACS, PubMed, Scopus, Web of Science, ScienceDirect databases from March 2017 to October 2018 with adult individuals (20-59 years). Bone health was evaluation performed through dual X-ray absorptiometry and serum concentrations of 25(OH)D. The random effect model was used to analyze data from bone mineral content and bone mineral. Random effects models were used and the sources of heterogeneity were explored by means of meta-regression. Thirty-five articles were selected. There was positive correlation between vitamin D and bone health in most of the evaluated sites. Correlation was observed in the analysis of subgroups for lumbar spine among men. When stratified, the studies presented high heterogeneity, which was explained by the sample size, mean serum vitamin D levels and risk of bias. Vitamin D is positively correlated to bone health in adult individuals.

Abstract The poultry sector in Pakistan is contributing mainly in bridging gap between demand and supply for protein. Mycoplasma gallisepticum is an emerging bacterium causing serious problems in poultry industry of Pakistan. A cross-sectional study was conducted to evaluate the M. gallisepticum load in poultry populated regions of Pakistan. Total 600 serum and 600 swab samples were collected, 200 from each broiler, layers and breeders poultry in Rawalpindi and Abbottabad districts. Serum samples were analyzed through ELISA for seroprevalence. Swabs were cultured on Frey’s medium followed by PCR and partial mgc2 gene sequencing. Results of seroprevalence of M. gallisepticum showed that layers (75%, n=150) are more positive as compared to breeders (70%, n=140) and broilers (50%, n=100). Typical colonies of the M. gallisepticum were observed in breeder (26.5%), followed by layer (21%) and broilers (9%). A total of 37.1% (n=42) samples were identified positive through PCR out of total 113 cultured based positive samples. A total of six M. gallisepticum isolates of current study showed 98-99 percent similarity with previously reported isolates on the basis of mgc2 gene partial sequencing. The M. gallisepticum was found highly prevalent in different poultry breads. Results of this study would add into basic data and provide a direction for livestock sector to strengthen a control strategy for mycoplasmosis in poultry farms.
Cultivando proliferações indomáveis: considerações antropológicas sobre as políticas de proteção à infância

Resumo Por uma reflexão voltada para políticas de adoção infantil, procuro estabelecer uma ponte entre, por um lado, episódios etnográficos - densos e contextualmente situados - e, por outro, sistemas abrangentes com consequências em larga escala e de longo alcance. Operacionalizo essa proposta pela análise das infraestruturas administrativa, estatística e burocrática que conectam as filosofias políticas do momento às atitudes e ações dos variados atores (profissionais, servidores e usuários) sob observação. Essa abordagem permite rastrear através das últimas décadas os instrumentos tecnológicos - em particular, estatísticas, cadastros e formulários - cunhados para estabilizar determinadas políticas de adoção. Ao mesmo tempo, atento às “proliferações” (Tsing; Mathews; Bubandt, 2019) - produto e produtor de tensões do próprio sistema - que levam acontecimentos em direções inesperadas. Ao apreciar esses eventos que iniciam quase sempre em escala limitada e com consequências incertas, minha intenção é restituir o poder desses exemplos a alimentar certa esperança - profundamente pragmática, epistemologicamente ambivalente e subarticulada - em possibilidades futuras ainda sequer imaginadas.
Impact driving of monopiles in centrifuge: effect on the lateral response in sand
Authors: Maatouk Semaan , Blanc Matthieu , Thorel Luc
Published: August 2021

This study examines the influence of impact-driven installation on the subsequent horizontal monotonic response of small-scale monopiles by using a large-beam geotechnical centrifuge at 100g. A special device including a small-scale hammer was developed to install open-ended monopiles 50 mm in diameter to an embedment depth of 250 mm in flight, and then to apply lateral loading on the monopile head without stopping the centrifuge. The horizontal global and local responses of the monopiles were investigated for two methods of installation: impact driven at 100g, and monotonically jacked at 1g into saturated dense sand. The results highlighted two main features. (a) The effect of impact driving was pronounced for small amplitudes of horizontal loading. With regard to the conditions of serviceability, the in-flight installation increased the secant stiffness by about three times compared with the 1g installation. For a large amplitude of displacement, the lateral capacity increased by 1.3 times. (b) The experimental p–y curves obtained from the in-flight impact-driven installation remained smoother than those predicted by using offshore standards, but were similar to them.
Vibration control of an irregular structure using single and multiple tuned mass dampers
Authors: Khan Imdad Ullah , Usman Muhammad , Tanveer Muhammad
Published: August 2021

The tuned mass damper is a passive control technique, which is used in high-rise building structures for mitigation of the vibration produced as a result of wind and earthquake loadings. Irregularity in structure increases the chances of vibrations produced from these loadings. In this paper, detailed experimental work was carried out for vibration mitigation of an irregular four-storey structure having mass irregularity at its fourth floor using a single tuned mass damper (STMD) and multiple tuned mass dampers (MTMDs), against different harmonic and seismic loadings; such work has never been carried out before. The positions of STMD and MTMDs were varied along each floor and all possible configurations of STMD and MTMDs were tested against these loadings. For comparison, the acceleration responses of each storey for all configurations of STMD and MTMDs were compared with that of the uncontrolled structure. It was found that under all types of loadings, the STMD reduces the acceleration response of all floors of the uncontrolled structure; similarly, all configurations of MTMDs show further reduction in acceleration response, demonstrating the efficiency of MTMDs over a STMD in irregular structures.

Geophysical Characterization of a Sinkhole Region: A Study toward Understanding Geohazards in the Karst Geosites
Authors: Yordkayhun Sawasdee
Published: August 2021

The outstanding geosites in Satun UNESCO Global Geopark, Thailand are mainly karst topography. Sinkhole which is originated from the dissolution of karst rocks by groundwater or acidic rainwater is one of the potential natural disasters in these geosites. To gain the confident among geotourism, detecting karst features, cavities and surficial dissolution is crucial in risk assessment and sustainable geopark management. As a part of geohazard assessment, non-invasive geophysical methods were applied for detecting near-surface defects and karst features. In this study, electrical resistivity tomography (ERT), seismic tomography and multichannel analysis of surface waves (MASW) have been integrated to understand the mechanism of an existing sinkhole formation in Satun Geopark region. ERT appeared to be an effective approach to investigate the cavity development at shallow subsurface. MASW and seismic tomography were combined to help constrain the interpretation of lithology and karst features in vicinity of the sinkhole. The results indicated that the sinkhole occurrence in this area was probably developed by forming of cavity due to an increased dissolution of the fractured limestone bedrock. This carbonate layer is in contact with the overlying groundwater and weathering shale or cohesive soil layer. The changing of water table and infiltration of surface water by heavy rainfall allowed for a sudden vertical downward of overlying sediments into the empty voids, leading to the sinkhole hazard.
Fluvial-Tidal to Fluvial-Lacustrine Sedimentation of the Middle Miocene to Pleistocene Mapia Formation, Dogiyai, Papua (Indonesia)
Authors: Fakhruddin Rakhmat
Published: August 2021

A sedimentological and palynological investigation was carried out on outcropping sedimentary rocks at Dogiyai, Papua, proposed to be named as the Mapia Formation. The age range is from Middle Miocene to Pleistocene. The lower Mapia Formation was deposited at Metroxylon type to Nothofagus emarcida Zone, Middle Miocene to Early Pliocene. It is comprised of three facies associations: tidal channel, tidal point bar, and tidal flat deposits. A tidally dominated fluvially influenced depositional environment is suggested for the deposition of sediments of this unit. The upper Mapia Formation was deposited at Malvacipollis diversus Zone, Garcinia cuspidata type Zone, and Proteacidites sp. Zone, Late Pliocene to Pleistocene. It is comprised of five facies associations: delta front, slump, debrite, turbidite, and lacustrine mud deposits. A non-channelized deep-lacustrine slump and debris-flow dominated depositional environment is suggested for the deposition of sediments of this unit. The lower Mapia Formation was deposited as synorogenic clastic sediments at the beginning of Central Range orogeny event while the upper Mapia Formation was deposited in the piggyback basin at the major uplift event.
Effect of Multi-Sized Graphite Filler on the Mechanical Properties and Electrical Conductivity
Authors: Mohd Radzuan Nabilah Afiqah , Sulong Abu Bakar , Iswandi Iswandi
Published: August 2021

This research successfully fabricated conductive polymer composites (CPCs) prepared using multiple sizes of graphite filler (40, 100, 150, and 200 µm) that provided excellent network formation within the fillers and polypropylene matrix which further improved both electrical conductivity and flexural strength. An important discussion on the fabrication technique, including compression moulding and injection moulding was conducted, to manufacture CPC materials with a thickness less than 3 mm. The findings of this study suggested that fabricating CPCs using the compression moulding technique with a graphite composition of 75 wt. % exhibited better network connectivity as the electrical conductivity increased to 15 Scm-1. Also, compared to the three sizes of graphite filler (40/100/200 µm) it resulted in 13 Scm-1, with two sizes (40/200 µm) reporting better electrical conductivity at 15 Scm-1. This demonstrated that the addition of multiple sizes was not necessarily due to agglomeration occurring. The resultant graphite composites of 40/200 µm possessed a more stable structure having a thin composite layer (2.5 mm) which promoted better electrical conductivity suitable for bipolar plate used in proton exchange membrane fuel cells.

Published: August 2021

The Pterion is a point of sutural confluence formed by frontal, parietal, temporal and sphenoid bones. Center of pterion is located 4cms above the midpoint of zygomatic arch and 3.5cms behind the fronto-zygomatic suture. Pterion is a reference landmark for many regions of the brain. Knowledge of various types of pterion is important in neurosurgeries as pterion keyhole approach has several advantages over traditional craniotomy; it has got radiological significance in interpretation of radiographs; in forensic medicine, it has been used for estimation of age and stature; and types of pterion has racial variations, hence it has got anthropological significance. Hence, the present study was taken to assess various types of pterion in South Indian adult human skulls.

To classify the types of pterion based on Murphy’s classification and compare the right and left sides.

The study was conducted on 100 adult dry human skulls collected from Kempegowda Institute of Medical Sciences & Research center, Bangalore. The various types of pterion were noted. All the readings were tabulated and subjected to analysis.

All measurements and frequencies of the data were tabulated. The mean, standard deviation for each of the measurements were assessed. Statistical software SPSS version 16 was used. Right and left side were compared using One-Way ANOVA (Analysis of Variance).

Various types of pterion were observed. Spheno-parietal was the most predominant (78%) type, followed by epipteric (16%), stellate (4%) and fronto-temporal (2%).

: The results of the present study can be utilized by neurosurgeons, radiologists, anthropologists and forensic experts. The findings can be used in future for comparing various types of pterion from a different population, race or species altogether.

Published: August 2021

Congenital Cleft Lip and Palate is a common birth defect with an incidence of 1 in 600 to 800 live births. This defect usually affects either the left, right or in some cases both sides of the lip and is called a Tessier Type 3 cleft. Clefting of the face in the midline is exceedingly rare and such a case of a Median Facial Cleft Syndrome is being reported which occurs in nearly 1 in 1,000,000 live births. This was first described by Bechard in 1823 and can be sporadic or part of an inherited syndrome. The child had a median cleft of the upper lip, nose, and palate of a severe, complete variety, with absent philtrum of the upper lip, premaxilla, columella, nasal septum and vomer.
The Universality of Palliative Care Philosophy
Authors: Gielen Joris
Published: August 2021

The modern hospice movement, which is the origin of what is now known as palliative care, derived strong inspiration from Christianity. Given this original Christian inspiration, the global spread of palliative care even to countries where Christianity is only a minority religion may look surprising. In line with the theory of the “secularization of hospice,” it could be argued that palliative care has spread globally because its underlying philosophy has become secular, allowing it to become universal. However, given the continuing importance of religion in many areas of palliative care, we could wonder how secular contemporary palliative care really is. This article argues that the universality of palliative care philosophy resides in its susceptibility to contextualization. Palliative care has become a global success story because people all over the world committed to palliative care’s principles and ideas have contextualized these and developed models of palliative care delivery and even philosophy that are adapted to the local socio-economic and cultural-religious contexts. This article analyzes palliative care in India to illustrate this point, describing contextualized models of palliative care delivery and showing that palliative care physicians and nurses in India draw inspiration from their local context and religiosity.

Optimal Site for Precordial Stethoscope Placement in Pediatric Patients Younger than Two Years: A Preliminary Cross-sectional Study
Authors: Ito Hidekazu , Mizuno Shoji , Iio Kenji
Published: August 2021

Background: The precordial stethoscope is a traditional and non-invasive monitoring method during pediatric general anesthesia. In this preliminary cross-sectional study, we aimed to investigate the characteristics of lung and heart sounds via precordial stethoscope and determine the optimal site for auscultation in children below 2 years of age.
Methods: This study involved 68 patients who underwent general anesthesia with tracheal intubation. Auscultation sounds via precordial stethoscope were recorded in MP3 format at the following three sites: Site A-region between the clavicle and nipple on the left midclavicular line; Site B-region between the nipple and costal arch on the left midclavicular line; and Site C-point on the left midaxillary line that was horizontally leveled with Site B. Eight blinded evaluators individually and randomly scored lung and heart sounds on a 10-point scale (0: cannot hear at all and 10: can hear clearly).
Results: Lung sound scores at Sites A, B, and C were 8.0 (7.0–9.0), 4.5 (2.9–6.0), and 7.0 (5.5–8.5), respectively, while heart sound scores at Sites A, B, and C were 3.5 (2.0–6.0), 6.5 (4.0–8.0), and 1.0 (0.4–2.0), respectively. Statistically significant differences were found in all pairs of sites.
Conclusion: We suggest that Site A, where anesthesiologists can hear both the lung and heart sounds, is the optimal site of precordial stethoscope attachment during general anesthesia for intubated children below 2 years of age.

Methods: during 66 days (20/02/2020 to 01/06/2020) all patients diagnosed with SARS-COV-2 infection referred to Valiasr Hospital in Arak were monitored. Thus, based on the pre-prepared questionnaire, the information of the mentioned patients was extracted from the Hospital Information System (HIS) by the required formats and after eliminating the incomplete cases, it was aggregated based on coding (to preserve the patients' information). The results were evaluated using spss. v25 software.
Results: Out of 535 patients with SARS-COV-2 included in the study, 295 (55%) were male and 240 (45%) were female. Women with a mean age of 61.03 years were significantly (p = 0.009) at a higher age than men with a mean age of 56.59 years. Nearly 60% (304 patients) of patients had a history of underlying disease. Gender comparison of patients with a history of underlying disease infected with SARS-COV-2 infection did not show any significant difference between male and female patients. Comparison of the mean age of the improved and dead patients shows that the mean age of the dead patients with a significant difference (P <0.001) was higher than the improved subjects. This result is also true for people with a history of underlying disease (p<0.0001). The number of patients with arterial oxygen saturation <93% was significantly higher in the group of patients with a history of at least one chronic underlying disease than who did not have any chronic disease (P <0.0001). The mortality rate in ICU patients was significantly higher than those admitted to the normal ward (p < 0.0001).
Conclusion: Aging, gender, underlying diseases and arterial oxygen saturation (<93%) at the time of admission have important role in the hospitalization rate, severity of the disease and mortality in patients with COVID-19.

Severe infection with COVID-19 disease can be associated with respiratory failure, kidney disorders, and in more advanced stages, organ failure and death. Unfortunately, there is currently no definitive cure for this disease, and damage to the immune system caused by inflammatory storms leads to widespread and varied complications that make an early diagnosis of the disease difficult. Therefore, eliminating or inhibiting the production of factors involved in inflammatory storms can be effective in improving the clinical condition of patients. According to specialized studies on the role of hemoperfusion in inhibiting advanced levels of COVID-19 disease, the present study was performed to investigate the use of hemoperfusion as a potential treatment option for this disease.

The rapid expansion of a novel human infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has evolved into a pandemic, affecting thousands of people world wild. Some patients with coronavirus disease 2019 (COVID-19) develop severe infection, which may progress to acute respiratory distress syndrome, multiple organ failure, and death. Increasing studies indicate that abnormal elevation of cytokine levels in response to SARS-CoV-2 may contribute to the pathological process that leads mortality of COVID-19. Thus, application of extracorporeal hemoperfusion (HP) for removal of excessive cytokines from the blood can potentially mitigate or reverse cytokine storm related complications of COVID-19.
Here, we presented series of COVID-19 patients, who were treated with HP (HA 380 cartridge, Jafron Biomedocal Co, China). The medical records were evaluated retrospectively to determine the effect of HP on patients’ clinical outcome. Our results showed that HP improvee PO2 and O2 saturation in patients with severe COVID-19. After the last courses of HP, 5 out of 6 patients were extubated and transferred to the general ward with an acceptable medical condition. The following case series demonstrate the promising role of HP in controlling the consequential effect of cytokine storm following a COVID-19 infection, which could facilitate patient survival.

This study was conducted to review the related articles and draw a final conclusion regarding the application of reflexology for delivery (labor and cesarean section) pain management in women all over the world. In this systematic review, relevant articles were searched in Google Scholar, PubMed, Cochrane Library, Science Direct, and Scopus databases from the year 2000 to 2018. All the human clinical trials that examined the effects of reflexology methods on delivery pain (labor or Cesarean section) were included, and others were excluded from the study. All the 18 included original articles (with 1391 patients) reported that reflexology significantly reduces the pain of delivery, confirming its decreasing effect on labor, Cesarean section, and post-delivery pain. Results of all articles showed that if true reflexology is performed on the right location of the body and at the appropriate time, the pain of delivery can be significantly decreased. Reflexology is appropriate pain relief and prophylaxis for any kind of pain, especially delivery and post-delivery pain. It is a safe remedy with no adverse effects reported so far.
Lipid-Based Nanocarriers Provide Prolonged Anticancer Activity for Palbociclib: In Vitro and in Vivo Evaluations

Published: August 2021

Breast cancer therapy has remained one of the major healthcare challenges. Based on the critical role of cyclin-dependent kinase 4/6 (CDK 4/6) in cell cycle progression, targeting this signaling appears promising for cancer therapy. Palbociclib, a selective CDKs 4/6 inhibitor, is the first-line treatment for estrogen receptor-positive breast cancer. However, poor absorption or side effects may negatively affect its efficiency. This prompted us to incorporate palbociclib into the nanostructured lipid carriers (NLCs) and evaluate the anticancer effect of the nanoformulation (Pa-NLCs) in in vitro and in vivo models of breast cancer. Pa-NLCs were developed by high-pressure homogenization followed by assessment of the physicochemical characteristics and bioactivities in MCF-7 breast cancer cells and female Wistar rats exposed to the carcinogen 7,12-dimethylbenz(a)anthracene (DMBA). The prepared Pa-NLCs demonstrated suitable physicochemical characteristics, including the controlled release pattern, efficient cellular uptake, and cytotoxicity, while free palbociclib failed to show significant effects. Rats treated with Pa-NLCs exhibited significantly reduced tumor volumes, increased survival rates, and histopathological improvement. Free palbociclib was significantly less efficient than Pa-NLCs. Pa-NLCs, by improving the pharmacological profile of palbociclib and providing longer-lasting effects, can be considered as a promising nanoformulation against breast cancer.

Cataract surgery sometimes is associated with adverse effects, such as dryness, burning, and patient discomfort. This study evaluates the treatment of dry eye syndrome and pain caused by corneal damage following cataract surgery with pregabalin compared to placebo. In our double-blind clinical trial, a total of 60 cases were divided into two groups. The pain score was assessed by the Numeric Rating Scale (NRS), and the impact of pain and dryness on the patient's performance was evaluated by the Brief Pain Inventory (BPI). The patient's pain score was evaluated postoperatively and followed for six weeks after the procedure. After the sixth week of the study, NRS, BPI, and photophobia in the pregabalin group were significantly different from the placebo group. Pregabalin can significantly reduce chronic and resistant eye pain after cataract surgery.

Published: August 2021

Factor VII deficiency is a rare congenital coagulopathy disorder. In most cases, this disorder is diagnosed in childhood. Common symptoms of congenital factor VII deficiency are different and consist of cutaneous, mucosal hemorrhage, gastrointestinal bleeding, and joint bleeding. CNS hemorrhage is a fatal and severe complication of congenital factor VII deficiency. The incidence of gross hematuria is a rare symptom of factor VII deficiency. Isolated presentation of hematuria is rarer and usually is accompanied by bleeding in other sites. The patient reported here is a 6-month-old girl who was diagnosed with congenital Factor VII deficiency following episodes of isolated gross hematuria. We decided to report this case to demonstrate if there is no other organic cause in the investigation of a child with recurrent hematuria, we should also consider a coagulation factors deficiency. Since isolated hematuria is a rare symptom in the coagulation factors deficiency, the coagulation tests may be of less interest.

Introduction: Impaction is one of the most common tooth abnormalities which has multiple pathological consequences. The purpose of this study is to assess the prevalence of impacted and semi-impacted teeth and to determine the impaction angle of different teeth in patients referred to the maxillofacial radiology department of dental school, Mazandaran University of medical sciences in years 2013-2019.
Material and Methods: The panoramic radiographs of patients who were referred to oral and maxillofacial radiology department of Mazandaran dental school were observed. Impaction or semiimpaction angle of third molars were determined by Winter’s classification. Statistical analysis were conducted by using Chisquare test, Fisher’s exact test, Mann Whitney U test and Spearman correlation test (α=0/05).
Results: 3200 panoramic radiographs were analyzed, and the prevalence of impaction, complete impaction and semiimpaction were calculated to be 25/8%, 3/7% and 23/6% respectively. The mesioangular impaction (48/3%) was the most prevalent kind of impaction. Statistically, age was correlated with the jaw involving tooth impaction (P=0/01), this correlation wasn’t observed about sex (P=0/161).
Conclusion: Impacted teeth were observed in approximately one third of the radiographs. Impaction was more common in the mandible and the most prevalent kind of impaction was determined to be the mesioangular impaction. As the impacted tooth can cause problems we conclude that they must be extractedat an early age.
