Enhanced recovery after surgery for hip fractures: a systematic review and meta-analysis
Authors: Liu Song-yang , Li Ci , Zhang Pei-xun
Published: September 2021

Background

Enhanced recovery after surgery (ERAS) programs have achieved promising results in many surgical specialties. However, uncertainty still remains regarding the effect of ERAS on hip fractures. The objective of this review was to investigate the clinical prognosis of ERAS programs in terms of (1) hospital-related endpoints (time to surgery [TTS], length of stay [LOS]), (2) readmission rate, (3) complications, and (4) mortality.

Methods

Published literature was searched in the PubMed, EMBASE, and Cochrane Library databases. All of the included studies met the inclusion criteria. The primary outcomes were TTS and LOS. The secondary outcomes included the 30-day readmission rate, overall complication rate, specific complication rate (delirium and urinary tract infection), and 30-day and 1-year mortality. Language was restricted to English. The data analysis was carried out by Review Manager 5.3.

Results

A total of 7 published studies (9869 patients) were finally included, and these were all cohort studies. The meta-analysis showed that the TTS, LOS, and overall complication rate were significantly reduced in the ERAS group compared with the control group (p < 0.01). Moreover, no significant change was found in the 30-day readmission rate or 30-day and 1-year mortality.

Conclusions

ERAS significantly decreases the TTS, LOS, and complication rate without increasing readmission rate and mortality, which adds to the evidence that the implementation of ERAS is beneficial to patients undergoing hip fracture repair surgeries.

Published: September 2021

Lightning strike is one of the natural disasters to the roof components of ancient buildings. To investigate the causes and damage effects of lightning strikes on the roofing glazed tiles of ancient buildings, artificial lightning strike tests were carried out on glazed tiles. Based on the experiment results, a coupled electrical–thermal finite element model of mortar-containing glazed tiles was established and the Joule heat effect of lightning current was further investigated. The results show that when the lightning channel is attached to the surface of the enamel and body with a low electrical conductivity, the lightning current is mainly released in the form of surface flashover, and a minor damage is induced along the flashover path; when the lightning channel is attached to the mortar with a high electrical conductivity, the lightning current is injected into the mortar, resulting in significant tile damage. The spatial distributions of the temperature present clear gradient characteristics. The high-temperature area appears in the mortar while the high–thermal–stress area appears in the body connected to the grounding rail. As the peak of the lightning current increases, both the high-temperature and high–thermal–stress areas of the glazed tiles expand. The combination of the experiments and the numerical analysis results demonstrate that the damage mechanism of lightning Joule heat effect to glazed tiles may include two aspects. One is the internal explosive force generated from the sharp vaporization and expansion of the moisture inside the tiles due to rapid temperature increase, and the other is the thermal stress caused by the uneven temperature distribution.
Monitoring of Paraquat in soya products intended for animal feed
Authors: Heydebreck Franziska
Published: September 2021

Even though paraquat is considered to be one of the most toxic herbicides, it is one of the most used ones. Paraquat-based preparations are heavily used across many important agricultural countries and for a lot of types of crops such as soya. As soya is used in large quantities in the feed production, paraquat residues in soya products are a potential threat to livestock. The aim of this study was to investigate whether soya products intended for animal feed contain residues of paraquat. Therefore, an optimized Quick Polar Pesticides (QuPPe) Method was developed. In total, 174 samples were analyzed via LC-MS/MS using zwitterionic hydrophilic interaction liquid chromatography (ZIC-HILIC). The results showed that paraquat was detected in 66 % of the samples above 0.008 mg/kg. Residues were mainly present in soya bean meals that were imported from Brazil or the USA and cultivated using genetically modified soya. Around 5 % of the samples were not compliant with the European regulation on maximum residue levels of pesticides in or on food and feed. The results of this study support the view that paraquat residues play a significant role in soya products intended for animal feed and, thus, need to be controlled on a regular basis. However, for enforcement actions reliable processing factors for paraquat in soya products or maximum residue levels for processed soya products are urgently required.
Near real time flood inundation mapping using social media data as an information source: a case study of 2015 Chennai flood
Authors: Karmegam Dhivya , Ramamoorthy Sivakumar , Mappillairaju Bagavandas
Published: September 2021

During and just after flash flood, data regarding water extent and inundation will not be available as the traditional data collection methods fail during disasters. Rapid water extent map is vital for disaster responders to identify the areas of immediate need. Real time data available in social networking sites like Twitter and Facebook is a valuable source of information for response and recovery, if handled in an efficient way. This study proposes a method for mining social media content for generating water inundation mapping at the time of flood. The case of 2015 Chennai flood was considered as the disaster event and 95 water height points with geographical coordinates were derived from social media content posted during the flood. 72 points were within Chennai and based on these points water extent map was generated for the Chennai city by interpolation. The water depth map generated from social media information was validated using the field data. The root mean square error between the actual water height data and extracted social media data was ± 0.3 m. The challenge in using social media data is to filter the messages that have water depth related information from the ample amount of messages posted in social media during disasters. Keyword based query was developed and framed in MySQL to filter messages that have location and water height mentions. The query was validated with tweets collected during the floods that hit Mumbai city in July 2019. The validation results confirm that the query reduces the volume of tweets for manual evaluation and in future will aid in mapping the water extent in near real time at the time of floods.
Endoscopic management of periventricular and intraventricular arachnoid cysts
Authors: Fayed Ahmed Abdel Aziz , Ibrahim Tamer , Rayan Tarek
Published: September 2021

Introduction

The most successful surgical management of periventricular and intraventricular cysts is still a matter of debate. Up to the early 1990s, open cyst fenestration and cystoperitoneal shunts were the only options available. Recently, different endoscopic approaches to these lesions have gained popularity.

Methods

Eighteen endoscopic procedures were performed for the treatment of arachnoid cysts in 18 patients. Sylvian fissure arachnoid cysts were excluded from this study. Ten of them were females and eight were males with their ages ranging from 6 months to 50 years with a mean of 16 years. All patients were prospectively observed.

Results

Seven of the arachnoid cysts were in the suprasellar region, 5 in the quadrigeminal region, 2 in the posterior fossa, 2 parietal, and 2 intraventricular. Seventeen cases (94%) had hydrocephalus. The main presenting manifestations were those of increased intracranial pressure. All fenestrations were done in the lateral ventricle except for the 2 cases with posterior fossa arachnoid cysts, the fenestrations were done to the fourth ventricle. Endoscopic ventriculocytostomies (VC) were performed in 14 cases without operative complications and no stents were placed. Endoscopic cystocisternostomies (C) were done in all suprasellar cases. Endoscopic cystoventriculostomies (CV) were done in 4 cases. The mean surgical time was 1 h. The mean follow-up period was 15 months. Symptoms improved in 17 cases. Seventeen cases demonstrated a significant decrease of the cysts’ size in the postoperative computed tomography (CT) and magnetic resonance imaging (MRI). A single case developed a complication in the form of subdural hygroma which required no intervention and was managed conservatively.

Conclusion

Endoscopic management of periventricular and intraventricular arachnoid cysts is a useful safe option in the management of arachnoid cysts related to the ventricular system.

Published: September 2021

Background: Cancer patients have been disproportionally affected by the coronavirus disease 2019 (COVID-19) pandemic, with high rates of severe outcomes and mortality. Fever is the most common symptom in COVID-19 patients. During the COVID-19 pandemic, physicians may have difficulty in determining the cause of fever (COVID-19, another infection, or cancer fever) in cancer patients. Furthermore, there are no specific guidelines for managing cancer patients with fever during the COVID-19 pandemic. Thus, this study evaluated the clinical characteristics and outcomes of cancer patients with fever during the COVID-19 pandemic. Methods: This study retrospectively reviewed the medical records of 328 cancer patients with COVID-19 symptoms (fever) admitted to five hospitals in Daegu, Korea from January to October 2020. We obtained data on demographics, clinical manifestations, laboratory test results, chest computed tomography images, cancer history, cancer treatment, and outcomes of all enrolled patients from electronic medical records.Results: The most common COVID-19-like symptoms were fever (n=256, 78%). Among 256 patients with fever, only three (1.2%) were diagnosed with COVID-19. Most patients (253, 98.8%) with fever were not diagnosed with COVID-19. The most common solid malignancies were lung cancer (65, 19.8%) and hepatobiliary cancer (61, 18.6%). Twenty patients with fever experienced a delay in receiving cancer treatment. Eighteen patients discontinued active cancer treatment because of fever. Major events during the treatment delay period included death (2.7%), cancer progression (1.5%), and major organ dysfunction (2.7%).Conclusion: Considering that only 0.9% of patients tested for COVID-19 were positive, screening for COVID-19 in cancer patients with fever should be based on the physician’s clinical decision, and patients might not be routinely tested.

Authors: Lipiec Dariusz
Published: September 2021

Duszpasterstwo osób z niepełną sprawnością to forma działalności Kościoła, urzeczywistniającą posługę zbawczą Kościoła przez głoszenie takim ludziom słowa Bożego, działalność liturgiczną, posługę pasterską i świadectwo życia chrześcijańskiego. Specyfika niepełnosprawności i życia ludzi obarczonych nią wymaga odpowiedniego przygotowania przez niterów do pracy z nimi. Formacja ludzka polega w tym przypadku na kształtowaniu cech charakteru potrzebnych do współpracy z ludźmi z niepełną sprawnością. Z kolei formacja duchowa zmierza do pogłębienia miłości pasterskiej na wzór Jezusa Chrystusa Dobrego Pasterza oraz postawy służebnej wobec takich osób. Celem formacji intelektualnej jest przekazanie potrzebnej wiedzy dotyczącej niepełnosprawności i ludzi, którzy zostali nią dotknięci, natomiast formacja pastoralna zmierza do pogłębiania odpowiednich postaw nabywania umiejętności duszpasterskich. Formacja prezbiterów do duszpasterstwa osób z niepełną sprawnością powinna mieć charakter całościowy i integralny.

Introduction

The carotid web is a compelling potential mechanism of embolic ischemic stroke. In this study, we aim to determine the prevalence of ipsilateral carotid web in a cohort of ischemic stroke patients and to perform a systematic review and meta-analysis of similar cohorts.

Patients & methods

We performed a retrospective, observational, cohort study of acute ischemic stroke patients admitted to a comprehensive stroke center from June 2012 to September 2017. Carotid web was defined on computed tomography angiography (CTA) as a thin shelf of non-calcified tissue immediately distal to the carotid bifurcation. We described the prevalence of carotid artery webs in our cohort, then performed a systematic review and meta-analysis of similar cohorts in the published literature.

Results

We identified 1,435 potentially eligible patients of whom 879 met criteria for inclusion in our analysis. An ipsilateral carotid web was detected in 4 out of 879 (0.45%) patients, of which 4/4 (1.6%) were in 244 patients with cryptogenic stroke and 3/4 were in 66 (4.5%) patients <60 years old with cryptogenic stroke. Our systematic review yielded 3,192 patients. On meta-analysis, the pooled prevalence of ipsilateral carotid web in cryptogenic stroke patients <60 was 13% (95% CI: 7%-22%; I2 = 66.1%). The relative risk (RR) of ipsilateral versus contralateral carotid web in all patients was 2.5 (95% CI 1.5–4.2, p = 0.0009) whereas in patients less than 60 with cryptogenic stroke it was 3.0 (95% CI 1.6–5.8, p = 0.0011).

Discussion

Carotid webs are more common in young patients with cryptogenic stroke than in other stroke subtypes. Future studies concerning the diagnosis and secondary prevention of stroke associated with carotid web should focus on this population.

Published: September 2021

The great powers utilized media as a tool of political communication and propaganda after the First World War. The leading role of propaganda during the Second World War enabled them to use media and develop media policy. The United Kingdom, as a pioneer of political communication, used the British Broadcasting Corporation (BBC) in order to influence public opinion. The BBC has developed since its inception and now plays an inimitable role in the UK media policy and diplomacy. This article examines the British media policy including regulations, approaches, management and strategies to clarify how the United Kingdom designs and operates its media-based policies in order to play effectively in the media back grounds. It uses the documentary method to answer the questions: what are the organizational and management structures, regulations, strategies and approaches of the British media policy? And how has the British media policy been developed to surmount the media regulation problems and challenges? This research indicates that the development of a smart-organized and well-regulated system of media policy enables the United Kingdom to utilize media to promote the priorities of the British foreign policy and influence public opinion around the world as well as to play a crucial role in media wars to protect its interests in international system.
Remembering Seonjeong Yi Lebrun: Mourning with narratives of care
Authors: Kwon Hyunji
Published: September 2021

It is hard to coherently narrate traumatic memories as they are intensely emotional and fragmented. I created this narrative inquiry in the hope of enacting care and performing mourning for the unexpected death of Seonjeong Yi Lebrun (1983–2017). Seonjeong was a Korean-born art education researcher in Canada whose work exemplified how artistic approaches to narrative evoke empathy and connectivity. Her research spanned arts-based self-study to participatory action research about comfort women (Korean sex slaves for the Imperial Japanese Army during the Second World War). In performing mourning for Seonjeong through examining her research, I endeavour to have my research possibly initiate a new form of arts-based collective care for her, comfort women and those suffering from other forms of trauma.
Reconciling with others, within oneself, and the circle(s) of time
Authors: Ulkuniemi Seija
Published: September 2021

This visual essay depicts my personal experiences with the San peoples of South Africa. Almost twenty years ago, I learned of a personal loss while examining their ancient rock carvings and used the San people’s beliefs about the reconciliation of death and nature to heal. In 2019, I ran a workshop for young Khoe-Sans peoples, offering them a chance to connect and find harmony within themselves. They shared their personal stories and visual creations with each other, reviving the disappearing storytelling tradition. As Indigenous peoples have often been treated as objects without respect, following the ethical rules of research was part of reconciliation. My approach throughout the workshop was to embody connectedness and care; according to the feedback, our interaction succeeded despite our cultural differences.
Bridging art viewing and making: Constructivist museum tour and workshop programmes
Authors: Yoo Juyoung
Published: September 2021

The purpose of this study is to investigate how constructivist approaches are conceptualized and implemented in ‘gallery tour and studio workshop’ educational programmes at art museums, and the relationship that exists between the gallery and studio learning for children. A qualitative multi-case study was employed, and three art museums were involved. Data collection methods included programme observations, participant interviews, photos and museum documents. The findings of the study offer examples of educators’ teaching approaches, which reflect constructivist tenets, as well as factors that might strengthen the connection across gallery and studio learning. An inviting learning environment, consideration of students’ prior knowledge and experience, use of themes and motivating questions and facilitation of reflections, as well as educators’ collaboration all promoted well-connected tour and workshop programmes. This study offers insights and strategies to interested museum professionals and educators who aim to provide children with meaningful and well-connected art-viewing and art-making programmes.
The perception of students’ pre-sketching by architecture educators
Authors: Alipour Leyla
Published: September 2021

Different individuals have different perception of artworks. This study aims to find the differences between architecture educators and other interpreters in perceiving architecture students’ pre-sketching. For this purpose, the images of architecture students’ pre-sketches were interpreted by three groups. The information perceived from the students’ pre-sketching was coded and categorized as description, analysis, cognition, emotion, artist and evaluation. The results indicate that the focus of architecture educators was on formal aspects, architects tended to notice students’ architectural abilities while interpretations of educators from other disciplines emphasized the perception of meaning and emotion. The results also show the special role of educators’ perception in education through art.

Published: September 2021

BACKGROUND: The Bryansk region is one of the regions of the Russian Federation most affected by the accident at the Chernobyl nuclear power plant on April 26, 1986.In the conditions of a chronic uncompensated deficiency of iodine in the diet in the first months after the accident, an active seizure of radioactive iodine by the thyroid tissue took place, which inevitably resulted in an increase in thyroid diseases from the population in the future. The article presents the results of a control and epidemiological study carried out in May 2021 by specialists of the National Medical Research Center of Endocrinology of the Ministry of Health of Russia, aimed at assessing the current state of iodine provision in the population of the Bryansk region.AIM: Assessment of iodine supply of the population of the Bryansk region.MATERIALS AND METHODS: The research was carried out in secondary schools of three districts of the Bryansk region (Bryansk, Novozybkov and Klintsy).The study included 337 schoolchildren of pre-pubertal age (8–10 years), all children underwent: measurement of height and weight immediately before the doctor’s examination, which included palpation of the thyroid gland (thyroid gland); Thyroid ultrasound using a portable device LOGIQe (China) with a multi-frequency linear transducer 10–15 MHz; determination of iodine concentration in single portions of urine. A qualitative study for the presence of potassium iodate in samples of table salt (n = 344) obtained from households and school canteens was carried out on the spot using the express method.RESULTS: According to the results of a survey of 337 pre-pubertal children, the median urinary iodine concentration (mCIM) is 98.3 μg / L (range from 91.5 to 111.5 μg / L, the proportion of urine samples with a reduced iodine concentration was 50.1%). According to the ultrasound of the thyroid gland, 17% of the examined children had diffuse goiter, the frequency of which varied from 9.4 to 29% in the areas of study. The share of iodized salt consumed in the families of schoolchildren in the study areas was 17.8% (values range from 15.6 to 19%), which indicates an extremely low level of iodized salt consumption by the population. All salt used for cooking in school canteen areas of the study was iodized, which confirms compliance with the requirements of SanPiN 2.4.5.2409–08.CONCLUSION: Despite the active implementation in the Bryansk region of various preventive programs of IDD and social activities to promote the use of iodized salt, in the absence of mass prevention with the help of iodized salt to date, their unsatisfactory results should be noted.

Authors: Mokrysheva N. G. , Kovaleva E. V. , Eremkina A. K.
Published: September 2021

The most important and effective way to organize nationwide the healthcare, as well as monitoring and routing for patients with endocrine diseases, is the creation of an unified medical record (Endocard). The Endocard is also aimed at maximizing the opportunity for professionals and researchers on various scientific issues. Registries are the potential informational and analytical platform to achieve this goal. They include the basic information on the epidemiological and clinical features of the most severe diseases such as diabetes mellitus. Given the lack of large-scale epidemiological data on the parathyroid glands pathology — primary hyperparathyroidism and hypoparathyroidism — the registers of these diseases that collects a common dataset and clinician and patient reported outcomes are of particular interest.

Published: September 2021

In this study, a techno-economic feasibility analysis of hybrid renewable energy systems for four household categories in rural areas of Chad was studied based on the multi-criteria assessment technique. The problem of this study is to know the best optimal solution in the technical and economic feasibility study of the decentralized mini-grids for the rural electrification of isolated villages in Chad. The main objective of the work is to assess technically, economically and environmentally the feasibility of six scenarios of hybrid systems in five isolated sites in Chad. The performance analysis involved six scenarios of possible hybrid solutions while achieving a supply-demand balance for sustainable electrification of the remote villages, using the HOMER software. The results have shown that the optimum combination of the hybrid system was the photovoltaic/battery system with a Net Present Cost (NPC) of US $ 328,146 and it was found at Etena village. The photovoltaic/Wind/Diesel/Battery hybrid configuration was the least optimum system and it has appeared in Mandelia village. In terms of energy cost, the lowest Levelized Cost of Energy (LCOE) was estimated at US $ 0.236/kWh in a photovoltaic/Wind/Battery configuration at Koundoul site and the highest costs US $ 0.363/kWh in the photovoltaic/Battery configuration at the Linia site. It is established that hybrid solutions can be developed to make electricity available and accessible to the population of the remote rural areas in Chad. However, it is imperative that the local government must subsidize the diesel price to promote the adaptation of the abundant renewable solutions.
Mind your Prayers. Aristotle’s Notion ofeuchê
Authors: Kontos Pavlos
Published: September 2021

In Aristotle’s world there is no God to answer our prayers (euchê) and yet prayers follow the excellent city of thePoliticslike a shadow. Nonetheless, as far as I know, people have been content to narrow the focus of investigation to Aristotle’s utopia, its plausibility, structure and infrastructure, leaving prayers out of the picture. The most prayers themselves seem to deserve is a footnote or so. The result is that attention is switched away from the most basic questions: What is the function of practical reason that prayers are meant to perform and why could not, or should not, that function be carried out by deliberate choices, wishes, and action plans? Prayers matter, and matter a lot, so I will argue, for they mirror our understanding ofconstitutivemoral luck. The legislators and the rulers who ignore or overlook this truth are theoretically incompetent and politically perilous.
Expert Impressions in Stoicism
Authors: Veres Máté , Machek David
Published: September 2021

We focus on the question of how expertise as conceived by the Stoics interacts with the content of impressions. In Section 1, we situate the evidence concerning expert perception within the Stoic account of cognitive development. In Section 2, we argue that the content of rational impressions, and notably of expert impressions, is not exhausted by the relevant propositions. In Section 3, we argue that expert impressions are a subtype of kataleptic impressions which achieve their level of clarity and distinctness due to the contribution of expertise. In Section 4, we argue that the expertise in living well not only allows the wise person to assent correctly but also affects the content of her impressions. We suggest that these two models – one’s attitude toward an impression being informed by expertise, and one’s impressions being affected by expertise – might characterize distinct stages of cognitive development. Stoic wisdom is not only a matter of the way one assents to one’s impressions but also a matter of the condition of one’s soul and, consequently, of the kinds of impressions one even entertains. Expertise offers a model of how cognitive and discriminatory improvement through practice and effort can transform the non-wise into the wise. A reading on which the content of impressions is not exclusively propositional illuminates a further aspect of this transformation. If the same propositions are accessible through impressions with different non-propositional content, we can account for cases in which the novice and the expert entertain the same proposition.
Do balanced-budget fiscal stimuli of investment increase its economic value?
Authors: Dosi Cesare , Moretto Michele , Tamborini Roberto
Published: September 2021

We examine the timing of a business investment providing valuable external benefits to society. A surge in uncertainty about private returns, a typical feature if not a cause of recessions, delays capital outlays to an extent that may be detrimental to social welfare. Is there an efficiency-improving public policy directed at accelerating investment? By real option analysis, we try answering this question by comparing three fiscal policies: (i) a simple subsidy on investment, (ii) a balanced-budget fiscal stimulus where the subsidy is subsequently covered by profit taxation, and (iii) by taxing external benefits as well. We show that, under a balanced-budget stimulus, investment acceleration may come at the expense of a net economic loss, and the higher is uncertainty on private returns, the higher the likehood of a negative outcome. However, this risk strongly declines when government spending is balanced by taxing both private and public returns on investment.
Political fact-checking in the Middle East: What news can be verified in the Arab world?
Authors: Fakida Abdelrahman
Published: September 2021

This study examines the news selection processes followed by fact-checking organizations in the Middle East, specifically Egypt, Jordan, and the United Arab Emirates, and gatekeeping such organizations face while working under authoritarian rule. By reviewing fact-checked news posted on the Facebook pages of six Arabic language organizations: Da Begad, HereszTruth, Fatabyyano, Matsad2sh, MisbarFC, and Saheeh Masr, this study manually analyzes about 5,000 fact-checked news stories to understand the extent of political fact-checking performed on Arab presidents, heads of government, and rulers, along with the most verified news topics. Results show that organizations in the Middle East rarely fact-check Arab rulers or refute their claims, while their news selection process prioritizes human interest topics. The study suggests that Arab fact-checkers resort to self-censorship due to gatekeeping influences that impact the region’s media climate.

J Strength Cond Res 36(4): 948–954, 2022—The purpose of this investigation was to examine the acute effects of resistance exercise (RE) and different manual therapies (static stretching and manual massage [MM]) performed separately or combined on blood pressure (BP) responses during recovery in women with normal BP. Sixteen recreationally strength-trained women (age: 25.1 ± 2.9 years; height: 158.9 ± 4.1 cm; body mass: 59.5 ± 4.9 kg; body mass index: 23.5 ± 1.9 kg·m−2; baseline systolic BP median: 128 mm Hg; and baseline diastolic BP median: 78 mm Hg) were recruited. All subjects performed 6 experiments in a randomized order: (a) rest control (CON), (b) RE only (RE), (c) static-stretching exercise only (SS), (d) MM only, (e) RE immediately followed by SS (RE + SS), and (f) RE immediately followed by MM (RE + MM). RE consisted of 3 sets of bilateral bench press, back squat, front pull-down, and leg press exercises at 80% of 10RM. Static stretching and MM were applied unilaterally in 2 sets of 120 seconds to each of the quadriceps, hamstring, and calf regions. Systolic (SBP) and diastolic BP were measured before (rest) and every 10 minutes for 60 minutes following (Post 10–60) each intervention. There were significant intragroup differences for RE in Post-50 (p = 0.038; d = −2.24; ∆ = −4.0 mm Hg). Similarly, SBP intragroup differences were found for the SS protocol in Post-50 (p = 0.021; d = −2.67; ∆ = −5.0 mm Hg) and Post-60 (p = 0.008; d = −2.88; ∆ = −5.0 mm Hg). Still, SBP intragroup differences were found for the MM protocol in Post-50 (p = 0.011; d = −2.61; ∆ = −4.0 mm Hg) and Post-60 (p = 0.011; d = −2.74; ∆ = −4.0 mm Hg). Finally, a single SBP intragroup difference was found for the RE + SS protocol in Post-60 (p = 0.024; d = −3.12; ∆ = −5.0 mm Hg). Practitioners should be aware that SS and MM have the potential to influence BP responses in addition to RE or by themselves and therefore should be taken into consideration for persons who are hypertensive or hypotensive.
A new species of Thomasomys Coues, 1884 (Rodentia: Sigmodontinae) from the montane forests of northern Peru with comments on the “aureus” group
Authors: Ruelas Dennisse , Pacheco Víctor
Published: September 2021

We describe a new species of the cricetid rodent Thomasomys (Sigmodontinae) of the "aureus" group based on four specimens collected from Carmen de la Frontera, Piura Department, Peru. This new species has a very long and white tail, very long mystacial vibrissae that extend posteriorly beyond the pinnae, and a distinctive cranial and dental morphology that differ from any other known species of Thomasomys. It is also one of the largest species of Thomasomys, exceeded in size only by T. apeco. A phylogenetic analysis using sequences of Cytb recovered this species within a non-monophyletic "aureus" group with a genetic distance between 5.47% (with T. auricularis) to 10.17% (with Thomasomys sp. 1). In addition to this finding, the phylogenetic position of T. apeco, T. praetor, and T. pyrrhonotus are presented for the first time, prompting a discussion on the nature of the "aureus" group.
Two new species of Kalcerrytus Galiano, 2000 (Araneae: Salticidae) from Tambopata River, Madre de Dios, Peru
Authors: Portuguez Bryan
Published: September 2021

Jumping spiders of the genus Kalcerrytus inhabit the moist tropical forests of the Neotropical region. This genus includes 18 species, only both sexes are known for half of these and of K. leucodon only the female is known; the vast majority of species are registered for Brazil and there are records from Bolivia, Ecuador and French Guiana. Males are characterized by having a robust palp and more sclerotized than in other genera of the Freyina subtribe; females are distinguished by their broad epigynum with large funnel-shaped copulation openings and oblique edges. Two new species are herein described, and they represent the first record of the genus in Peru. Kalcerrytus mapinguari sp. nov. and Kalcerrytus yacuruna sp. nov. were collected in the Tambopata River region, which is characterized by its highly biodiverse tropical lowland evergreen forests. Illustrations of both male and female genitalia are provided as well as maps recording their distribution.

Published: September 2021

A parasitological survey searching monogeneans infesting marine fish was carried out during June 2018 and January 2020 from the coastal zone of Puerto Pizarro, Tumbes (northern Peru) and from the coastal zone of Chorrillos, Lima (central Peru). The gills, skin, nasal cavities, or branchial gill-cover of seven species were sampled. Ten monogenean species assigned to six families and nine genera were identified. The monogeneans Callorhynchocotyle callorhynchi (Manter, 1955); Capsala biparasiticum (Goto, 1894) Price, 1938; Euryhaliotrema sagmatum Kritsky & Boeger, 2002; Listrocephalos kearni Bullard, Payne &Braswell, 2004; Magniexcipula lamothei Bravo-Hollis, 1981; Nasicola klawei (Stunkard, 1962) Yamaguti, 1968; and Pseudorhabdosynochus anulus Violante-Gonzalez & Rojas-Herrera, 2011 are registered for the first time in Peru. While Capsala gregalis (Wagner & Carter, 1967) Chisholm & Whittington, 2007; Heterocotyle margaritae Chero, Cruces, Sáez, Santos & Luque, 2020; and Monocotyle luquei Chero, Cruces, Iannacone, Sanchez, Minaya, Sáez & Alvariño, 2016 have been previously registered in Peruvian waters, however, the region of Tumbes (northern Peru) represent a new locality record for these species.

Authors: Gabay Polina G. , Dronova Sophia A.
Published: September 2021

The article presents a legal analysis of the procedure for providing medical care in pediatric oncology and hematology which regulates the provision of medical care to children with neoplasms and diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism. The place of the pediatric oncology and hematology profile in the system of existing regulatory legal acts and the role assigned by the new procedure to the pediatric oncologist are determined. The requirements to the structure of medical organizations providing medical care in pediatric oncology and hematology profile, the procedure of oncological and hematological diseases diagnosis and management are considered. Attention is drawn to the lack of timescales of pediatric oncologist-hematologist consultation and taking biopsic material. The algorithm of medical organizations actions on entering data into information systems is analyzed.

Aim. To assess whether delayed coronary artery stenting (CAS) can reduce the slow/no-reflow incidence in patients with ST-segment elevation myocardial infarction (STEMI) and massive thrombosis (TTG ≥3) of the infarct-related coronary artery (IRCA) compared with immediate CAS within primary PCI.

Material and methods. Out of 3651 primary PCIs performed for acute STEMI in the period from January 2016 to May 2020 at the Mytishchi City Clinical Hospital, the retrospective analysis included 105 patients with massive IRCA thrombosis (TTG ≥3). The patients were divided into two groups: first group (n=55) — delayed CAS, second group (n=50) — immediate CAS. In the immediate CAS group, the PCI procedure ended with routine stent implantation, and in the delayed CAS group, stent implantation was delayed for at least 5 days.

Results. In the delayed CAS group in comparison with immediate one, the slow/no-reflow phenomenon developed much less frequently in the form of a significant increase in the prevalence of TIMI 3 flow, better myocardial perfusion of myocardial blush grade (MBG) 2-3 (81,8 vs 64%; odds ratio (OR) 2,53; p=0,039) and ST segment resolution ≥70% (87,3% vs 58%; OR 4,97; p=0,001).

Conclusion. Delayed CAS in patients with STEMI with massive thrombosis (TTG ≥3) of IRCA reduces the risk of slow/no-reflow phenomenon and can be considered as a possible alternative treatment vs immediate CAS, provided that stable coronary flow is restored before TIMI 3.

Aim. To assess the contribution of genetic and inflammatory factors to the development of arrhythmogenic right ventricular cardiomyopathy (ARVC).

Material and methods. The study involved 54 patients with ARVC (age, 38,7±14,1 years; men, 42,6%; mean follow-up period, 21 [6; 60] months). All patients underwent electrocardiography (ECG), 24-hour ECG monitoring, echocardiography, determination of anticardiac antibodies and DNA of cardiotropic viruses in the blood, molecular genetic ARVC testing, as well as cardiac magnetic resonance imaging (n=49), high-resolution ECG (n=18), right ventricular endomyocardial biopsy (n=2), and autopsy (n=2).

Results. Following four clinical types of ARVC were identified: I. Latent arrhythmic form: characterized by frequent premature ventricular contractions and/or nonsustained ventricular tachycardia (VT). II. Manifested arrhythmic form (n=11) — SVT/ventricular fibrillation (VF). III. ARVC with progressive heart failure (HF, n=8). IV. Combination of ARVC with left ventricular noncompaction (LVNC, n=8). Superimposed myocarditis was identified in 74%, 36%, 87,5% and 85,7% of patients in forms I-IV, respectively. Mutations were detected in 11%, 46%, 50%, and 38% of patients in forms I-IV, respectively. Clinical forms were stable: there was no transition from one clinical form to another during follow-up period.

Conclusion. The contribution of genetic and inflammatory mechanisms to the clinical picture is different: in the latent arrhythmic form, the leading role belongs to inflammation; in the manifested arrhythmic form, the contribution of pathogenic mutations prevails, and in ARVC with progressive HF and in combination with LVNC, the contribution of genetic and inflammatory factors is equally important.
