Choosing Discourse Types That Align With Person-Centered Goals in Aphasia Rehabilitation: A Clinical Tutorial
Authors: Leaman Marion C. , Archer Brent
Published: March 2023

Purpose:

People with aphasia and their families want rehabilitation services that improve real-world communication. Thus, clinicians and researchers have increased focus on discourse-level interventions and outcome measures, most often using monologue tasks to assess discourse production and guide treatment planning. However, communication in everyday life usually involves participating in conversational discourse. This mismatch raises concern because the literature indicates that different types of discourse possess different linguistic and interactional characteristics and that the communication skills of people with aphasia vary across different types of discourse. In order to provide appropriate, client-centered services, speech-language pathologists (SLPs) need resources that outline the linguistic and interactional characteristics of each type of discourse. Few user-friendly materials of this sort exist. This tutorial aims to equip clinicians with essential foundational knowledge regarding features of narrative, procedural, and expository monologue, as well as conversation, to aid in the design of discourse-level interventions specific to each individual's discourse needs.

Method:

This tutorial provides an overview of the research regarding the structure and function of commonly assessed and treated forms of discourse, along with findings regarding the varied and unpredictable communicative performance of people with aphasia across the different types of discourse. We then provide practical applied clinical examples to illustrate the literature findings.

Conclusion:

Given the differences between types of discourse, when SLPs include discourse in a client's treatment program, the types of discourse activities the client wants to address should align very closely with the types of discourse assessed and treated in the clinic room.
Efficient ear alignment using a two‐stack hourglass network
Authors: Hrovatič Anja , Peer Peter , Štruc Vitomir , Emeršič Žiga
Published: March 2023

Ear images have been shown to be a reliable modality for biometric recognition with desirable characteristics, such as high universality, distinctiveness, measurability and permanence. While a considerable amount of research has been directed towards ear recognition techniques, the problem of ear alignment is still under‐explored in the open literature. Nonetheless, accurate alignment of ear images, especially in unconstrained acquisition scenarios, where the ear appearance is expected to vary widely due to pose and view point variations, is critical for the performance of all downstream tasks, including ear recognition. Here, the authors address this problem and present a framework for ear alignment that relies on a two‐step procedure: (i) automatic landmark detection and (ii) fiducial point alignment. For the first (landmark detection) step, the authors implement and train a Two‐Stack Hourglass model (2‐SHGNet) capable of accurately predicting 55 landmarks on diverse ear images captured in uncontrolled conditions. For the second (alignment) step, the authors use the Random Sample Consensus (RANSAC) algorithm to align the estimated landmark/fiducial points with a pre‐defined ear shape (i.e. a collection of average ear landmark positions). The authors evaluate the proposed framework in comprehensive experiments on the AWEx and ITWE datasets and show that the 2‐SHGNet model leads to more accurate landmark predictions than competing state‐of‐the‐art models from the literature. Furthermore, the authors also demonstrate that the alignment step significantly improves recognition accuracy with ear images from unconstrained environments compared to unaligned imagery.
Towards a more flexible demand responsive transit service with compensation mechanism considering boundedly rational passengers
Authors: Wang Hongfei , Guan Hongzhi , Qin Huanmei , Zhao Pengfei
Published: March 2023

Demand responsive transit (DRT) with app‐based reservation platforms is experiencing a renaissance to bring the tremendous potential for mobility in the urban universe. Nevertheless, how to attract and retain passengers for long‐term use has become one of the most significant problems. The decision‐making psychology of passengers is often overlooked but incredibly critical in the practical applicability of DRT services. This paper proposes a more flexible DRT service with soft time windows considering boundedly rational passengers. A compensation mechanism is developed to alleviate the dissatisfaction of passengers while considerably promoting the system efficiency. A two‐stage model is designed to incorporate bounded rationality into the optimization process of mixed demand, including the static phase for reservation passengers and the dynamic phase for real‐time passengers. To enhance the computational efficiency, a hybrid heuristic algorithm combining spatiotemporal clustering and non‐dominated sorting genetic algorithm (NSGA)‐II is constructed to obtain the Pareto solutions set. An illustrative example of the Nguyen–Dupuis network is presented to demonstrate the validity of the algorithm. Subsequently, a large‐scale case study in Beijing evaluated the applicability of DRT in the real‐world network. The results reveal that dynamic DRT with compensation mechanism can substantially improve the system performance while ensuring the service quality. The response rate of passengers has been dramatically promoted to 80%. The operating profit has been enormously improved by up to 73%. Therefore, this study is radically conducive to understanding the passenger's decision‐making psychology while constructing a more cost‐efficient flexible strategy for the service provider.
1D recursive median filter based passive islanding detection strategy for grid‐connected distributed generations network
Authors: Mumtaz Faisal , Imran Kashif , Rehman Habibur , Bukhari Syed Basit Ali
Published: March 2023

In modern distribution networks, integration of distributed generations (DGs) at consumer premises is common. However, islanding detection in such a grid‐tied distributed generation (GTDG) network is the topmost challenge to ensure power quality and reliable operation. This paper presents a modified passive islanding detection scheme (MPIDS) for the GTDG network, using a One‐D recursive Median filter (ODRMF) algorithm. Firstly, at the point of common coupling (PCC), 3‐phase voltage is acquired. Next, the ODRMF is employed to extract 3rd harmonic and residuals from the acquired voltage signal. Afterward, two novel islanding detection indices developed are: (1) First change detection (FCD), which is calculated from the residuals, and (2) delta selected harmonic distortion (∆SHD), which is computed from 3rd harmonic content of the voltage signal. Finally, variations in the two indices are compared with the threshold to identify islanding. To validate the efficacy of the presented MPIDS, rigorous simulations in MATLAB/ Simulink are conducted on the UL‐1741 and IEEE 13‐bus GTDGs systems under different conditions. The results illustrate that the presented strategy is highly reliable in all assessed conditions and can detect the islanding as well as non‐islanding incidents effectively under balanced and unbalanced load/generation conditions with a very low non‐detection zone.
A localization scheme based on Improving Dynamic Population Monte Carlo Localization method for large‐scale mobile wireless aquaculture sensor networks
Authors: Lv Chunfeng , Zhu Jianping , Chen Gang
Published: March 2023

Localization is one of the essential problems in wireless sensor applications (WSNs). Most range‐free localization schemes for mobile WSNs are based on the Sequential Monte Carlo (SMC) algorithm. Multiple iterations, sample impoverishment and less sample diversity, leading to low localizing efficiency, are the most usual problems demanding to be solved in these SMC‐based methods. An improved localization scheme for mobile aquaculture WSNs based on the Improving Dynamic Population Monte Carlo Localization (I‐DPMCL) method is proposed. A population of probability density functions is proposed to approximate the unknown location distribution based on a set of observations through an iterative mixture importance sampling procedure, accompanied by node dynamic behaviours being analysed quantitatively or definitely. Threefold constrain rules are put forward in the I‐DPMCL scheme to decrease the iteration number and trade off iteration number and enough valid samples to obtain the optimum iteration number. Then, these localization behaviours, especial delay, are predicted based on the statistical point of view. Moreover, performance comparisons of I‐DPMCL with other SMC‐based schemes are also proposed. Simulation results show that delay of I‐DPMCL has some superiority to those of other schemes, and accuracy and energy consumption are improved in some cases of lower mobile velocity.
Decay of a photospheric transient filament at the boundary of a pore and the chromospheric response
Authors: Lindner P. , Schlichenmaier R. , Bello González N. , de la Cruz Rodríguez J.
Published: March 2023

Context. The intermediate stages between pores and the formation of sunspots are a rare phenomenon and can be manifested as transient photospheric penumbral-like filaments. Although the magnetic field changes rapidly during the evolution of such filaments, they have not yet been shown to be connected to magnetic reconnection events.

Aims. We characterize the evolution of transient photospheric filaments around a pore and search for possible signs of chromospheric responses.

Methods. We analyzed observations of a pore in NOAA AR 12739 from the Swedish Solar Telescope, including the spectropolarimetric data of the Fe I 6173 Å and the Ca II 8542 Å line and spectroscopic data of the Ca II K 3934 Å line. The VFISV Milne-Eddington inversion code and the multi-line non-LTE inversion code STiC were utilized to obtain atmospheric parameters in the photosphere and the chromosphere.

Results. Multiple filamentary structures of inclined magnetic fields are found in photospheric inclination maps at the boundary of the pore, although the pore had never developed a penumbra. One of the filaments shows a clear counterpart in continuum intensity maps, in addition to photospheric blueshifts. During its decay, a brightening in the blue wing of the Ca II 8542 Å line is observed. The Ca II K 3934 Å and the Ca II 8542 Å lines show complex spectral profiles in this region. Depth-dependent STiC inversion results using data from all available lines yield a temperature increase (roughly 1000 K) and bidirectional flows (magnitudes up to 8 km s−1) at log τ = −3.5.

Conclusions. The temporal and spatial correlations of the decaying filament (observed in the photosphere) to the temperature increase and the bidirectional flows in the high photosphere and low chromosphere suggest that they are connected. We propose scenarios in which magnetic reconnection happens at the edge of a rising magnetic flux tube in the photosphere. This would lead to both the decay of the filament in the photosphere as well as the observed temperature increase and the bidirectional flows in the high photosphere and low chromosphere.

Published: March 2023

Shallot (Allium cepaL.) is one of the strategic commodities in Indonesia, where the Province of West Nusa Tenggara (NTB) is the third largest shallot-producing area. The main constraint in shallot cultivation is the limited availability of certified seeds and the weather strongly influences the cultivation. This paper discusses the impact of the 2021 weather anomaly on shallot seed production in West Lombok Regency, NTB Province, Indonesia. To produce and supply shallot seeds, the Super Phillip variety was planted in the period of May-June 2021 on farmers' land with an area of 4,000 m2of alluvial soil. There was a weather anomaly in June 2021, in the form of high rainy days up to 12 days and an increase in rainfall of 176 mm (414%) above normal, resulting in damage to the bulb enlargement phase andFusariumdisease attacks on plants older than 40 days which resulted in harvest failures. This weather anomaly resulted in crop failure and losses in almost 100% of shallot seed production. To anticipate failures and minimize risks to the shallot farming system in the future, it is necessary to learn and transfer technology to interpret rainfall prediction information and design a shallot planting calendar.

Published: March 2023

Shallots are strategic horticultural commodities, and climatic conditions strongly influence their growth. In certain seasons, a decline in production is unavoidable, causing price increases at a consumer level and eventually contributing to the rate of inflation. The application of Good Agriculture Practices (GAP) is a strategy that can maintain and increase the productivity of shallots. This study aimed to determine the effect of applying GAP on the growth and yield of shallots in several varieties developed in North Maluku. The research was carried out in Trans Koli SP-1 Village, Oba District, Tidore Islands City, from March – June 2015. The study was arranged in a factorial, the first factor was cultivation habits (GAP and farmer habits), and the second factor was varieties (Topo-1, Topo-2, Super Philips, and Thailand), which used a Randomized Block Design with three replications. Parameters observed were plant growth, the intensity of pests and diseases, yield components and the production of shallot bulbs. The results showed no interaction between cultivation habits and varieties in all parameters, but there were significant differences between the research cultivation habits and varieties in all parameters. The Super Philips variety generally had significantly higher growth and lower intensity of armyworms than the Topo-1, Topo-2, and Thailand varieties. In terms of yield and tuber production, Super Philips and Thailand varieties have significantly higher yields than Topo-1 and Topo-2. The results of this study confirmed that the application of GAP had a better effect on growth, pest intensity, and production of shallots than farmers' habits.

Published: March 2023

Red spinach (Amaranthus tricolor L) contains vitamins (A, B2, B6, K, and folate), proteins, carbohydrates, fats, minerals, fiber, iron, magnesium, manganese, potassium, and calcium. Red spinach also contain anthocyanins (red pigments) that function as antioxidants to prevent free radical oxidation. The use of biofertilizers can give benefits to the soil and plants. Mycorrhizal fungi can be used as a type of biological fertilizer. The application of arbuscular mycorrhizal fungi (AMF) in powder dosage forms can help the growth of plants. However, this dosage form has disadvantages, so a study is needed to determine the effectiveness of AMF in various dosage forms. This study applied the Latin Square Design (LSD), with three treatments of AMF propagule dosage forms, namely: tablets, sachets, and powders, without AMF application as a comparison/control. The results showed that the effectiveness of AMF propagule in dosage form sachets provided a reasonable infection rate with fertile plant growth and harvest index value was not significantly different from other dosage forms, due to the attack of plant-disturbing organisms before harvest. So, further research is needed to determine the effect of the AMF propagule dosage form in physiological review without invasion of plant-disturbing organisms.

Published: March 2023

In order to stabilize the supply and price of shallots in Indonesia, a production development program was held outside Java. Pontianak City is one of the areas for the development of shallot production in West Kalimantan. The level of demand for Pontianak City increases every year. This indicates an increase in consumption per capita. The problem of shallots in Pontianak is the high price fluctuations. This does not only occur at the consumer level, but also at the producer level. The method used was descriptive qualitative to analyze the shallot supply chain with framework FSCN, while descriptive quantitative for measuring supply chain performance with an operational efficiency and price efficiency. The sampling technique used was purposive sampling and snowball sampling. The results showed that shallots already have a clear target market and the chain structure consists of 2 marketing channels. Supply chain actors consist of farmers, collectors, distributors, agents and retailers. The contractual agreements that occur are informal and the relationship between the actors is well structured. Supply chain performance shows marketing channels 1 and 2 have not been efficient and prices have not been transmitted properly.

Published: March 2023

Social forestry was expected to improve the welfare of local communities by supporting people who live near the forest and rely on its natural resources while preserving their forests. The social forestry business was focused on managing all potential resources (Non-Timber Forest Products and Timber Forest Products) over its area's development as well as environmental services. In this regard, providing only legal access is not quite sufficient. It should be followed by strengthening business capital for forest farmers as their most basic problem was limited capital for their business development. The government has answered this matter by providing a Revolving Fund Facility, also known as Fasilitas Dana Bergulir (FDB), to forest farmers. In accordance with those elaborations, this study aimed to analyze forest farmers’ characteristics who received the FDB program benefits and to investigate the FDB impact on their Economic. This study was conducted on the selected community forest farmers group in Tebat Pulau Village as the largest beneficiaries of the fund in Rejang Lebong, Bengkulu Province. This study uses exploratory and descriptive-analytical methods. The economic impact of the FDB Program is increased production (76%), income, and employment (20%). Regression analysis proves that land area, number of workers, and partnerships positively affect income. The types of partnerships that have been carried out are bringing in Off Takers, capital support, education and training, equipment assistance, provide counselling. Furthermore, the determinants of income are the number of workers, the proportion of transportation costs, the proportion of input costs, the type of partnership, the appropriate use of funds, and their involvement in planning.

Weiterhin lag der höchste Anteil von MRSA an S.
aureus-Isolaten 2016 bei 23,1%.

Schlussfolgerungen und klinische Relevanz Da die für
Kaninchenschnupfen kausalen Bakterien meistens in den tieferen Bereichen der
Nase vorzufinden sind und der Nasenvorhof häufig mit ubiquitären
und coliformen Bakterien kontaminiert ist, wäre es sinnvoll, tiefe
Nasentupferproben bzw. idealerweise Nasenspülproben zu entnehmen.
Aufgrund der nachgewiesenen Erregervielfalt und einer mit der Erkrankung
einhergehenden Langzeittherapie sollte im Rahmen der Behandlung ein Antibiogramm
durchgeführt werden. Liegt kein Antibiogramm vor, ist Enrofloxacin wegen
seiner sehr guten Resistenzlage und Verträglichkeit Mittel der ersten
Wahl. Da jedoch Chinolone als „kritische“ Antibiotika eingestuft
werden, sollte ihr Einsatz auf ein Minimum beschränkt werden.
Tibial Plateau Leveling Osteotomy in small and large breed dogs: a
comparative retrospective study of complications and outcomes
Authors: Schuenemann Riccarda , Kaczmarek Jakub
Published: March 2023

Objective To compare complication rates and outcomes of small and large
breed dogs that had locking plate Tibial Plateau Leveling Osteotomy (TPLO)
performed due to cranial cruciate ligament disease during the same time period
at a single institution and identify potential influencing factors.

Material and methods 136 cases with TPLO performed at a single institution
between January 2013 and December 2015 were retrospectively reviewed. Dogs were
grouped by plate sizes (2.0, 2.4, 2.7, 3.5 and 3.5 broad) and by small breeds
(2.0–2.7 plate sizes) and large breeds (3.5 plates). Potential
influencing factors on lameness and complications were recorded from the
database and measured on radiographs and statistically compared.

Results Small dogs experienced fewer complications than large dogs
(10% vs. 22%) and not a single major complication. Small dogs
were significantly less lame at recheck and at long-term follow-up. Progression
of bone healing had an influence on the lameness grade of dogs at recheck after
TPLO. Distance of the most proximal screw from the joint was identified as a
risk factor for implant failure. The width of the patella ligament correlated
with body weight and uniformly increased 2.4 times after TPLO.

Conclusions TPLO in small breed dogs has a lower overall complication rate
than in large breed dogs. The TPLO plate should always be placed as close to the
joint as possible to reduce the risk of implant failure.

Clinical relevance TPLO can be recommended as treatment for cranial
cruciate ligament rupture (CCLR) in dogs of all sizes.

Die Homöopathie hat sich seit ihrer Entdeckung stark weiterentwickelt.
Engagierte Kolleginnen und Kollegen haben viel Energie in die Entwicklung von
weiteren Zugangswegen zum am besten helfenden Arzneimittel gesteckt. Was treibt sie
an? Profit und Renommee? Mit der Homöopathie ist beides nicht sehr einfach
zu erlangen. Forschergeist und der Wunsch, auch schwer zu behandelnden Patienten zu
helfen? Vermutlich schon eher. Auch gehören Homöopathen sicher nicht
gerade zu den Konformisten in der Medizin. So zeichnen sich die meisten Kollegen
durch ein hohes Maß an Individualität und Freiheitsliebe aus. Was in
unserer Zeit, in der ein Drang nach Vereinfachung, schnellen Lösungen und
Leitlinien besteht, nicht einfach ist.
Myxosarkom in der Halsregion eines Teddy-Hamsters (Mesocricetus
auratus)
Authors: Olivier Jessica , Weiler Kristina , Hartung Svenja , Weyrich Angelika , Bauer Natali
Published: March 2023

Dieses Fallbeispiel zeigt ein bisher selten beschriebenes Myxosarkom in der
ventrolateralen Halsregion eines 1-jährigen Teddy-Hamsters. Die
zytologische Beurteilung eines Feinnadelaspirats aus der Umfangsvermehrung
zeigte zahlreiche pleomorphe Spindelzellen, die in hohen Mengen in einer
muzinösen Matrix gelegen waren. Zytologisch wurde aufgrund der
ausgeprägten Malignitätskriterien der Spindelzellpopulation der
Verdacht auf eine maligne mesenchymale Neoplasie geäußert. Die
Matrix war dabei hinweisend auf ein zugrundeliegendes Myxosarkom. Der Hamster
verstarb im Rahmen der operativen Entfernung der Zubildung. Die Histopathologie
zeigte eine vollständige Übereinstimmung mit den zytologischen
Befunden. In der Immunhistochemie stellte sich der Tumor Vimentin-positiv mit
Alzianblau-positiver Matrix dar und bestätigte die zytologische
Verdachtsdiagnose. Der Fall zeigt, dass die Zytologie als minimalinvasives
Diagnostikum auch beim Kleinsäuger angewendet werden kann und
Rückschlüsse auf die zugrundeliegende Pathologie von Zubildungen
ermöglicht. Zum biologischen Verhalten des Myxosarkoms beim Hamster ist
aufgrund der seltenen Fallbeschreibungen jedoch bislang wenig bekannt.

Published: March 2023

Objectives Canine eosinophilic bronchopneumopathy (EBP) is a poorly
understood disease characterized by chronic inflammation of the lower airways.
To date, factors affecting the course of the disease are largely unknown. The
objective of this study was to investigate the influence of clinical,
laboratory, and environmental factors on therapeutic outcome in dogs with
EBP.

Material and methods Environmental and housing conditions, course of
disease, and response to treatment were evaluated using a standardized
questionnaire for owners of 29 dogs diagnosed with EBP from 3 different
veterinary referral centers in Germany. Data of diagnostic tests (hematology,
radiographs, bronchoalveolar-lavage-fluid-(BALF) cytology) were retrospectively
obtained from medical records. The influence of the different factors was
assessed using Fisher's-exact-test and Mann-Whitney-U- or
Kruskal-Wallis-test.

Results The proportion of neutrophilic granulocytes in BALF-cytology was
significantly higher in dogs with persistent clinical signs compared to dogs
that achieved clinical remission (p=0.029). Duration of clinical signs
before treatment was significantly longer in dogs with persistent clinical signs
(16±12 months) compared to dogs that achieved clinical remission
(6±7 months) (p=0.017).

Conclusion Early diagnosis and therapy have a decisive influence on the
success of treatment.

Clinical relevance Dogs with respiratory signs suspicious for EBP should
be evaluated in a timely manner to increase the likelihood of clinical remission
with an early start of therapy.
Baseline CT-Based Risk Factors for Atrioventricular Block after Surgical AVR
Authors: Claes Marie , Pollari Francesco , Mamdooh Hazem , Fischlein Theodor
Published: March 2023

Background We aimed to evaluate the impact of membranous interventricular septum (MIS) length and calcifications of the native aortic valve (AV), via preoperative multidetector computed tomography (MDCT) scan, on postoperative atrioventricular block III (AVB/AVB III) and permanent pacemaker implantation in surgical aortic valve replacement (SAVR).

Methods We retrospectively analyzed preoperative contrast-enhanced MDCT scans and procedural outcomes of patients affected by AV stenosis who underwent SAVR at our center (June 2016–December 2019). The study population was divided into two groups (AVB and non-AVB), and variables were compared with a Mann–Whitney's U-test or chi-square test. Data were further analyzed using point biserial correlation and logistic regression.

Results A total of 155 (38% female) patients (mean age of 71.2 ± 6 years) were enrolled in our study: conventional stented bioprosthesis (N = 99) and sutureless prosthesis (N = 56) were implanted. A postoperative AVB III was observed in 11 patients (7.1%). AVB patients had significant greater calcifications in left coronary cusp (LCC) -AV (non-AVB = 181.0 mm3 [82.7–316.9] vs. AVB = 424.8 mm3 [115.9–563.2], p = 0.044), LCC left ventricular outflow tract (LVOT) (non-AVB = 2.1 mm3 [0–20.1] vs. AVB = 26.0 mm3 [0.1–138.0], p = 0.048), right coronary cusp (RCC) -LVOT (non-AVB = 0 mm3 [0–3.5] vs. AVB = 2.8 mm3 [0–29.0], p = 0.039), and consequently in total LVOT (non-AVB = 2.1 mm3 [0–20.1] vs. AVB = 26.0 mm3 [0.1–138.0], p = 0.02), while their MIS was significantly shorter than in non-AVB patients (non-AVB = 11.3 mm [9.9–13.4] vs. AVB = 9.44 mm [6.98–10.5]; p=0.014)). Partially, these group differences correlated positively (LCC -AV, r = 0.201, p = 0.012; RCC -LVOT, r = 0.283, p ≤ 0.001) or negatively (MIS length, r = −0.202, p = 0.008) with new-onset AVB III.

Conclusion We recommend including an MDCT in preoperative diagnostic testing for all patients undergoing surgical AVR for further risk stratification.
Cerebral toxoplasmosis with neurological co-infection in people living with AIDS/HIV: results of a prospective cohort in São Paulo, Brazil
Authors: Telles João Paulo Marochi , Vidal José Ernesto
Published: March 2023

Background Concomitant neurological diseases in people living with HIV/AIDS (PLWHA) is a challenging subject that has been insufficiently evaluated by prospective clinical studies. The goal of the present study was to identify the clinical characteristics and outcomes of PLWHA with cerebral toxoplasmosis and neurological co-infections.

Methods We conducted a prospective observational cohort study at a tertiary teaching center in São Paulo, Brazil, from January to July 2017. Hospitalized PLWHA aged ≥ 18 years with cerebral toxoplasmosis were consecutively enrolled. A standardized neurological examination was performed at admission and weekly until discharge or death. Diagnosis and treatment followed institutional routines; neuroradiology, molecular diagnosis, neurosurgery, and the intensive care unit (ICU) were available. The main outcomes were neurological coinfections and in-hospital death.

Results We included 44 (4.3%) cases among 1,032 hospitalized patients. The median age was 44 (interquartile range [IQR]: 35–50) years, and 50% (n = 22) of the patients were male. The median CD4+ T lymphocyte count was of 50 (IQR: 15–94) cells/mm3. Multiple lesions on computed tomography were present in 59% of the cases. Neurological coinfections were diagnosed in 20% (n = 9) of the cases, and cytomegalovirus was the most common etiology (encephalitis: n = 3; polyradiculopathy: n = 2). Longer hospital stays (30 versus 62 days; p = 0.021) and a higher rate of ICU admissions (14% versus 44%; p = 0.045) were observed among PLWHA with neurological coinfections in comparison to those without them. The rate of in-hospital mortality was of 13.6% (n = 6) (coinfection group: 33%; no coinfection group: 8.6%; p = 0.054).

Conclusion Neurological c-infections were common among PLWHA with cerebral toxoplasmosis, and cytomegalovirus was the main copathogen. The group of PLWHA with neurological co-infections underwent longer hospital stays and more frequent intensive care unit admissions. Additionally, this group of patients tended to have higher in-hospital mortality rate.

Authors: Coutinho Léo , Teive Hélio A. Ghizoni
Published: March 2023

Rita Levi-Montalcini was a researcher in the field of neuroscience, Italian and Jewish in origin, who discovered the nerve growth factor and rightfully earned the 1986 Nobel Prize in Physiology or Medicine, alongside her collaborator Stanley Cohen. She was persecuted by the fascist dictatorship of Benito Mussolini and experienced gender and religious discrimination throughout her entire life. Despite these obstacles, she carried out her activities with diligence and grace, becoming a role model in the field. This paper reviews the life and career of Rita Levi-Montalcini.
