Acute piriformis syndrome mimicking cauda equina syndrome: illustrative case
Authors: Lodin Jan , Brušáková Štěpánka , Kachlík David , Sameš Martin , Humhej Ivan 
Published: November 2021

BACKGROUND
This report depicts a rare case of acutely developed urinary retention as well as sensory and motor disturbances caused by formation of a large hematoma within the piriformis muscle, which caused compression of nerves within the suprapiriform and infrapiriform foramina, thus imitating cauda equina syndrome. Although cases of acute lumbosacral plexopathy have been described, this case is the first time both urinary retention and sensory and motor disturbances were present.

OBSERVATIONS
The most useful tools for diagnosis of acute piriformis syndrome are detailed patient history, magnetic resonance imaging (MRI) of the pelvic region, and electrophysiological testing performed by an experienced electrophysiologist. As a result of diligent rehabilitation, including physiotherapy and electrostimulation, the patient was able to successfully recover, regardless of acute compression of the sacral plexus that lasted 6 days.

LESSONS
Clinicians should actively ask about previous pelvic trauma when taking a patient history in similar cases, especially if the patient is receiving anticoagulation treatment. If MRI of the lumbar spine does not reveal any pathologies, MRI of the pelvic region should be performed. Acute surgical decompression is crucial for preserving neurological function. In similar cases, it is possible to differentiate between spinal cord, cauda equina, and pelvic lesions using electrophysiological studies.
Biodiversitätsförderung im Wald durch Eingriffe: eine Wirkungskontrolle anhand von Fallstudien
Authors: Bühler Christoph , Roth Tobias 
Published: November 2021

Abstract
Das Programm «Naturschutz im Wald» wird im Kanton Basel-Landschaft seit 1998 umgesetzt. Nach 15 Jahren Laufzeit erfolgte auf Anordnung des Kantonsparlaments eine Wirkungskontrolle, mit welcher der Effekt naturschutzorientierter Eingriffe auf licht- und wärmebedürftige sowie auf totholzgebundene Pflanzen- und Tierarten untersucht wurde. Die Wirkungskontrolle beruht auf 31 Fallstudien, die in 13 verschiedenen Waldreservaten gemacht wurden. Die Fallstudien bezogen sich auf die Bestandestypen lichter Wald, Eichenwald, Mittelwald und Felsstandorte. Je nach Fallstudie wurden verschiedene Organismengruppen mit unterschiedlichen Erhebungsmethoden untersucht: Gefässpflanzen, Totholzkäfer, Schnecken, Brutvögel und Tagfalter. Die Wirkung der Eingriffe wurde entweder mittels «before-after»-Vergleich oder «control-impact»-Vergleich ermittelt. Eine Metaanalyse zeigte, dass die Indikatorarten von den ausgeführten Pflegeeingriffen profitieren. Die typischen Indikator-Gilden warmer und lichtreicher Waldgesellschaften waren auf Untersuchungsflächen mit Eingriffen signifikant artenreicher und häufiger vorhanden als auf den Kontrollflächen ohne Eingriffe beziehungsweise vor den Eingriffen. Obwohl der Abschluss der Untersuchung im Kanton Basel-Landschaft bereits sieben Jahre zurückliegt, ist sie eines der bisher wenigen Beispiele für eine umfassende Wirkungskontrolle zur Biodiversitätsförderung im Schweizer Wald. Die Vorteile, aber auch die Grenzen eines auf Fallstudien basierenden Ansatzes zur Wirkungskontrolle werden diskutiert und die Anforderungen an geeignetes Datenmaterial aufgezeigt.

O trabalho objetivou realizar uma revisão bibliográfica com base em artigos a cerca do material reciclável, o vidro, desde seu processo de fabricação, reciclagem, logística reversa e, até mesmo, a atuação de cooperativas e a situação dos catadores frente à coleta deste material tão importante. Entre os resíduos sólidos gerados no Brasil, o vidro se destaca pelo seu volume elevado, sendo apenas 14% desse material destinado à reciclagem. A reciclagem normalmente é realizada pelas próprias empresas produtoras desses vidros, em um processo denominado de logística reversa. Assim, a logística reversa atua em parceria com a empresa e, principalmente, com o meio ambiente, não gerando tanto impacto ambiental, e otimizar matéria prima e energia, diminui os custos para a empresa desde sua produção. Além disso, a atuação de cooperativas na reciclagem possibilita que catadores tenham uma melhor qualidade de vida. Portanto, a reciclagem do vidro gera grandes benefícios para a sociedade e o meio ambiente.

Published: November 2021

A própolis é um material recolhido de fontes vegetais pelas abelhas, sendo usada para promover um ambiente asséptico na colmeia, embalsamar invasores, reparar frestas, além de promover manutenção de parâmetros ambientais, como temperatura e umidade. Possui várias atividades biológicas reconhecidas, tanto no meio popular quanto no científico, a citar: antioxidante, antimicrobiana, cicatrizante, anestésica, anti-inflamatória, dentre outras. Existem diversos tipos de própolis, a depender de fatores ambientais (tipo de vegetação visitada pelos insetos, clima ou estação do ano), além de fatores relacionados às próprias abelhas. Sua composição química é muito variada, sendo o grupo mais importante o dos flavonoides. O objetivo desse trabalho foi realizar uma revisão bibliográfica, a fim de investigar a atividade anti-inflamatória que já vinha sendo atribuída a própolis há séculos. A busca por artigos e teses em português, inglês e espanhol, publicados nos últimos 10 anos, foi realizada nas seguintes bases de dados: SciELO, Google Acadêmico, PubMed, MEDLINE, Catálogo de Dissertações e Teses da CAPES, BVS, CRD, Embase, Science Direct, Scopus e Cochrane Library. Os artigos obtidos ao final da pesquisa trouxeram diversos experimentos, in vivo e in vitro, utilizando própolis dos mais diversos tipos, coletadas em regiões e países diferentes. Os resultados foram muito favoráveis em relação aos extratos de própolis, que conseguiram atingir valores potenciais nos testes anti-inflamatórios, principalmente quando comparados com substâncias isoladas já reconhecidas como bons anti-inflamatórios. Ainda, muitos trabalhos trouxeram informações sobre os possíveis mecanismos moleculares da própolis, como inibição de enzimas específicas, bem como da produção de mediadores inflamatórios.

Published: November 2021

В статье рассматривается проблема отсутствия актуальных сведений о подземных коммуникациях, расположенных в границах муниципальных образований. Данный аспект негативно отражается на эффективности использования земельных ресурсов органами государственной власти и органами местного самоуправления в рамках управления развитием территорий, а также при проектировании и строительстве объектов градостроительной деятельности. Разрозненность информации, содержащейся в Едином государственном реестре недвижимости (ФГИС ЕГРН) и Федеральной государственной информационной системе территориального планирования (ФГИС ТП) затрудняет разработку и использование проекта планировки территории в целях устойчивого развития территорий.
Для решения обозначенной проблемы предлагается включение в состав комплексных кадастровых работ технологической операции по установлению местоположения подземных коммуникаций и внесение соответствующих сведений о них в ЕГРН. Кроме этого, учитывая актуальность интеграции градостроительной и кадастровой деятельности, предлагается объединить информацию, содержащуюся в ФГИС ЕГРН и ФГИС ТП, на базе единой цифровой информационной платформы в 3D формате.
Rapid Loss of Dissolved CO2 From a Subtropical Steep Headwater Stream

Published: November 2021

High-gradient headwater streams are major participants in the carbon (C) cycle because of their capabilities of emitting a significant amount of carbon dioxide (CO2). Notwithstanding, their CO2 emissions have been largely overlooked in previous studies owing to their small water surface area and are sometimes strenuous to be measured because of their narrow channel widths and strong turbulence. This study examined the spatial and seasonal variabilities of CO2 dynamics of a subtropical steep headwater stream fed by groundwater. Our study found that the pH and dissolved oxygen exhibited a general increasing trend away from the source of the headwater whereas the partial pressure of carbon dioxide (pCO2) showed a downward trend. The stream water pCO2 in the upper reach was found to be higher than the ambient level by 19–114 times, with an average drop of &gt;70% at just 9.2 m from the groundwater source, demonstrating the potentially large emission of CO2 into the atmosphere within this short distance. Additionally, the sampling works conducted further downstream revealed that the CO2 derived from groundwater could almost completely dissipate within approximately half a kilometer downstream of the source. The concentrations of dissolved organic carbon and pCO2 were also lower during the period with lower air temperatures in the headwater stream, indicating temperature-dependent metabolism and decomposition of organic matter in soil might modulate the C dynamics in the headwater stream, although the rapid gas exchange along the stream remained the determinative factor. Our findings reassert that headwater streams are an essential source of CO2 and disregarding them from the studies of greenhouse gas emissions of inland waters would underestimate their potency to influence the global C cycle.
Rapid Northwestward Extension of the East Asian Summer Monsoon Since the Last Deglaciation: Evidence From the Mollusk Record
Authors: Dong Yajie , Wu Naiqin , Li Fengjiang , Lu Houyuan 
Published: November 2021

The magnitude and rate of the expansion of the East Asian summer monsoon (EASM) rain belt under future climatic warming are unclear. Appropriate ecological proxy data may provide an improved understanding of the spatial extension of the EASM during past warming intervals. We reconstructed the spatiotemporal pattern of the extension of the EASM since the Last Glacial Maximum (LGM), using six well-dated mollusk fossil sequences from Chinese loess sections located on the modern northern edge of the EASM. The abundance of typical dominant mollusk species indicative of EASM intensity shows a delayed response, from ∼17 ka in the southeastern sections to ∼9 ka in the northwestern sections, during the last deglacial warming. Isoline plots based on a mollusk data synthesis show that the mollusk EASM indicators have a northeast–southwest zonal distribution for both the present-day, the cold LGM, and the warm mid-Holocene, which is consistent with the spatial pattern of modern precipitation. The resulting estimated expansion rate of EASM intensity accelerated during ∼12–9 ka (∼50 km/ka), which corresponds to the early Holocene interval of rapid climatic warming, a northwestward shift of ∼150 km compared to today. This implies that the northern fringe of the EASM in northern China will become wetter in the coming century, under moderate warming scenarios.

Published: November 2021

BackgroundConvalescent plasma therapy is expected to be a promising alternative to supportive therapy during the SARS-CoV-2 pandemic outbreak. Altered immune response in repetitive convalescent plasma donors has not been widely studied. This case series was reported to analyze the patterns of immune responses and the factors that might influence them in repetitive convalescent plasma donors and increase awareness of COVID-19 survivors to donate their convalescent plasma.Cases IllustrationThere were five repetitive donors who were eligible as convalescent plasma donor requirements. It was found two donors who showed increment of anti-SARS-CoV-2 IgG level after donation and two others who showed persistent anti-SARS-CoV-2 IgG level more than two months after recovered.DiscussionThere was a difference in immune response in survivors who have the probability of being exposed to same antigens with survivors who did not, where the group of survivors who are at risk of exposure to antigens after recovery could trigger anamnestic immune response that can increase antiSARS-CoV-2 IgG levels. The other factor that influence the prolongation of anti-SARS-CoV-2 IgG levels are the possibility of neutralizing antibodies in plasma upregulation.ConclusionImmunological phenomenon in SARS-CoV-2, both in survivors and convalescent plasma donors, have not been widely observed and studied. From the case series discussed above, it can be concluded that convalescent plasma donation does not yet have strong evidence of decreasing levels of specific antibodies against SARS-CoV-2 and plasmapheresis procedure is safe to be done without reducing the protective effect of donor antibody post-plasma donation.

Published: November 2021

Objective: To investigate the early warning and prognostic evaluation of fecal calprotectin (FC), D-lactic acid, and bedside gastrointestinal ultrasound (B-GIUS) data for acute gastrointestinal injury (AGI) in sepsis patients.Main Method: Sepsis patients were grouped based on the presence or absence of AGI into AGI and non-AGI groups. Healthy volunteers of the same period were selected as the control group. FC, B-GIUS data, D-lactic acid, etc. were collected on the 1st, 3rd and 7th days of admission. Twenty-eight-day mortality was recorded.Main Results: FC, D-lactic acid levels, gastric antrum cross-sectional area, and small intestine wall thickness were significantly increased in group A and B (P &lt; 0.05); furthermore, inner-to-outer diameter ratio and cross-sectional area of small intestine were lower than those in the control group (P &lt; 0.05). FC, D-lactic acid, gastric antrum cross-sectional area and small intestine wall thickness in AGI group were higher than those in non-AGI group (P &lt; 0.05). Inner-to-outer diameter ratio and cross-sectional area of small intestine in AGI group were smaller than those in non-AGI group (P &lt; 0.05). There was no difference in the thickness, inner-to-outer diameter ratio nor the cross-sectional area ratio of colon between AGI and non-AGI groups (P &gt; 0.05). AUC for D-lactic acid was 0.881, which was higher than FC's (0.74). When the D-lactic acid cutoff value was 22.16 μmol/L, the sensitivity was 77.9% and the specificity was 92% for the prediction of AGI in sepsis. AUC for the cross-sectional area of the gastrointestinal antrum was 0.657, which was higher than the small intestine thickness's (0.629). When the gastric antrum cross-sectional area was larger than 4.20 cm2, the sensitivity was 64% and the specificity was 65.3%.Conclusion: D-Lactic acid and FC were early diagnostic indicators for sepsis with AGI, and D-lactic acid was the superior indicator. The gastric antrum cross-sectional area and the small intestine wall thickness had an early warning effect, and the prediction of the gastric antrum cross-sectional area was superior to that of the latter. Because it is non-invasive and convenient, B-GIUS can help in the diagnosis of sepsis with AGI.

Objective: Parkinson’s disease (PD) is the second most common neurodegenerative disease in the elderly. In early stages of PD, patients typically display normal brain magnet resonance imaging (MRI) in routine screening. Advanced imaging approaches are necessary to discriminate early PD patients from healthy controls. In this study, microstructural changes in relevant brain regions of early PD patients were investigated by using quantitative MRI methods.Methods: Cerebral MRI at 3T was performed on 20 PD patients in early stages and 20 age and sex matched healthy controls. Brain relative proton density, T1, T2, and T2′ relaxation times were measured in 14 regions of interest (ROIs) in each hemisphere and compared between patients and controls to estimate PD related alterations.Results: In comparison to matched healthy controls, the PD patients revealed decreased relative proton density in contralateral prefrontal subcortical area, upper and lower pons, in ipsilateral globus pallidus, and bilaterally in splenium corporis callosi, caudate nucleus, putamen, thalamus, and mesencephalon. The T1 relaxation time was increased in contralateral prefrontal subcortical area and centrum semiovale, putamen, nucleus caudatus and mesencephalon, whereas T2 relaxation time was elevated in upper pons bilaterally and in centrum semiovale ipsilaterally. T2′ relaxation time did not show significant changes.Conclusion: Early Parkinson’s disease is associated with a distinct profile of brain microstructural changes which may relate to clinical symptoms. The quantitative MR method used in this study may be useful in early diagnosis of Parkinson’s disease. Limitations of this study include a small sample size and manual selection of the ROIs. Atlas-based or statistical mapping methods would be an alternative for an objective evaluation. More studies are necessary to validate the measurement methods for clinical use in diagnostics of early Parkinson’s disease.

Published: November 2021

Background: Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) often causes various neurological sequelae, necessitating early and objective differentiation of AESD from a febrile seizure (FS). Therefore, we developed a scoring system that predicts AESD onset using only early laboratory data.Methods: We selected patients with AESD or FS admitted to the Tottori University Hospital between November 2005 and September 2020 and collected laboratory data from onset to discharge in patients with FS and from onset to the second neurological events in patients with AESD.Results: We identified 18 patients with AESD and 181 patients with FS. In comparison with patients with FS, patients with AESD showed statistically significant increases in ammonia (NH3), blood sugar (BS), and serum creatinine (Cr) levels, and the white blood cell (WBC) count, and a significant decrease in pH at &lt;3 h from onset. We set the cut-off values and adjusted the weight of each of these parameters based on data obtained &lt;3 h from onset and proposed a scoring system for predicting AESD. This system showed 91% sensitivity and 94% specificity for distinguishing AESD from FS. These accuracies were only slightly improved by the addition of information related to consciousness and seizure duration (sensitivity, 91%; specificity, 96%).Conclusion: NH3, BS, and Cr levels, WBC count, and pH were significantly different between patients with AESD and patients with FS at &lt;3 h from seizure onset. This scoring system using these data may enable the prediction of AESD onset for patients under sedation or without precise clinical information.
