Paraneoplastic anti-Yo antibody mediated subacute cerebellar degeneration. Case series and literature review
Authors: Vaišvilas M. , Mameniškienė R. , Barkauskienė A.
Published: June 2020

Paraneoplastic neurologic syndromes are a subgroup of diseases due to indirect cytotoxic effects of the immune system on specific brain structures rather than the mass effect itself. Paraneoplastic anti-Yo antibody mediated subacute cerebellar degeneration is characterised by an insidious onset, a characteristic neurologic syndrome of cerebellar dysfunction, normal or near/normal brain imaging on MRI, and gynaecologic malignancies identified by thorough investigation in middle aged post-menopausal women. Despite various aggressive treatments available, the prognosis is often considered poor. We present two cases with classical findings consistent with paraneoplastic subacute cerebellar degeneration and give literature review.
VIBRATION ANALYSIS OF THE TOOL BEARING SPINDLE IN CASE OF SUPERFINISHING TECHNOLOGIAL PROCESSES ESTABLISHMENT OF THE GENERAL MOVEMENT EQUATIONS
Authors: Popescu Daniel
Published: June 2020

The paper presents a mathematical model for determining the general movement equations that describe the vibration movement of the tool bearer spindle at superfinishing operations. There are presented the specific problems and the work schematics. The mathematical model uses the axioms of kinetic impulse and moment derivatives. At superfinishing, the spindle is eccentric and its working position is vertical. A series of simplifying assumptions are used, such as: Bernoulli’s hypothesis, the movement is without shocks, there are no remnant tensions, the strains are of elastic nature only. There are emphasized the components of the movement equations under restricted matrix form. The effect of transversal contraction and the torsion vibrations are neglected.

Authors: Berdyukova I. V. , Rudenko P. A.
Published: June 2020

Feline panleukopenia is a highly contagious viral disease of the members of the family Felidae caused by a DNA-virus of the family Parvoviridae. After infection, the virus is detected in saliva, nasal discharge, urine and feces; it is transmitted through excrements, water, food, and, according to some reports, by bloodsucking insects. The disease is characterized by gastrointestinal tract, central nervous system, hematopoietic tissue lesions. The paper describes the clinical signs of panleukopenia in cats in the territory of the Donetsk People’s Republic. Based on the records of a state-financed veterinary hospital and a charitable animal shelter located in the town of Yasinovataya, as well as those of private veterinary clinics and a veterinary office located in Donetsk, a classification of the clinical signs of the disease in pet and stray cats is suggested with the signs grouped according to their occurrence rate and by age groups. The paper provides evidence of feline panleukopenia occurrence in the territory of the Donetsk People’s Republic. In particular, the period from 2015 to 2018 was characterized by an increase in panleukopenia morbidity in stray animals; pet cats were also involved in the epidemic process. It was found that most of the clinical symptoms of panleukopenia were reported in cats of all age categories irrespective of their sex. Specific symptoms characteristic for different age groups were reported. It was found that panleukopenia morbidity rates for stray kittens aged 0–12 months were 1.8 times higher than those for pet kittens of the same age group. The disease was reported in adult pet cats 2.4 times less frequently than in stray cats. It is shown that the number of the disease cases in female cats is 1.5 times higher than in male ones. It is concluded that the violation of quarantine rules and insufficient vaccination coverage in cats are risk factors for the disease outbreak occurrence precipitating the multiple recurrent outbreaks of the disease.
Agr-typing of methicillin-susceptible Staphylococcus aureus (MSSA) isolated from non-human primates
Authors: Kalashnikova V. A.
Published: June 2020

Staphylococcus aureus (S. aureus) is a microorganism that causes a great number of diseases in humans and animals, including sepsis, pneumonia, food toxicoinfections, wound abscess, etc. Numerous studies on genotyping S. aureus strains isolated from humans, food and mastitis in cattle and small ruminants have been carried out. The lack of information on the genotyping of methicillin-susceptible S. aureus detected in monkeys served as a stimulus to conduct a similar research, since staphylococcal infections in the primates are widespread. The present study is devoted to molecular genetic testing of S. aureus isolated from different biological samples taken from monkeys and is based on typing of agr polymorphic locus which acts as a regulator of pathogenic gene expression. As a result of PCR analysis of 301 S. aureus isolates it was established that most of S. aureus belonged to agr IV (55%), and agr I (34%) was the second most group. Data resulting from the study differ from the results of other researchers published in literary sources, who performed typing of salmonella isolated from people with agr I prevailing. In conducting the study, neither distinct correlation between microbial isolation source and agr complex groups, nor relationship between the diseases and S. aureus group specificity were detected. Prevalence ratio of each agr group is nearly similar in S. aureus isolated from rhesus macaques and crab-eating macaques. But in hamadryas baboons and green monkeys II and III groups of agr complex were not detected.
Studies of biofilms and phenotypic characteristics of Candida fungi
Authors: Lenchenko E. M. , Sachivkina N. P.
Published: June 2020

Yeast-like fungi of the genus Candida are causative agents of the infectious pathology of the mucous membrane of the gastrointestinal, respiratory, urogenital tracts and skin of mammals, sepsis, and disseminated infection in birds. The search and testing of multilevel algorithms for biofilm identification when exposed to chemotherapeutic and disinfectant drugs for blocking the synthesis or destruction of the intercellular matrix in the development of superficial, deep and systemic candidiasis of animals are relevant for developing and improving diagnostic and antiepidemic measures. It was established that the formation of biofilm heterogeneous structure comprises multiple stages implementing the processes of intercellular communication due to the synthesis of a polymer matrix composites. Optical microscopy revealed a three-dimensional structure of biofilms in the form of a dense network consisting of yeast cells, hyphal and pseudohyphalic forms surrounded by an intercellular polymer matrix. Candida spp. pathogenicity factors contribute to infection of susceptible species due to adhesion, invasion, secretion of hydrolases, dimorphism. Formation of mono-species or poly-species biofilms of microorganisms, including Candida spp., causes the development of superficial, deep and systemic candidiasis. Detection of a large amount of yeast and micellar phases in C. albicans and C. africana isolates was a differential sign of a significant degree of colonization of the mucous membranes of the larynx, pharynx, and tonsils in case of local and systemic pathologies in pigs. The results of studies of the biofilm heterogeneous structure and phenotypic signs of yeast-like fungi can be used in a comparative study of biological characteristics and the identification of common patterns and differential signs of microorganisms, optimization of mycological diagnostics, and also in the development of antimycotic drugs.

Published: June 2020

More than 30,000 samples of blood serum from domestic, wild and synanthropic birds from 50 regions of the Russian Federation were submitted to the FGBI “ARRIAH” (Vladimir) Reference Laboratory for Avian Viral Diseases to be tested for avian influenza and Newcastle disease within the framework of monitoring activities conducted by the Rosselkhoznadzor in 2019. As a result of the laboratory diagnosis, antibodies to type A influenza virus were detected in vaccinated chickens from two poultry farms in the Perm and Primorsky Krais (A/N9). The detected antibodies were specific to the haemagglutinin subtype of the vaccine antigen. As for the backyards in the RF Subjects, where scheduled vaccination against avian influenza A/H5 is carried out, a low level of immunity was seen in the Rostov and Astrakhan Oblasts (35 and 44%, respectively) while a high level of immunity was observed in the Republic of Altai, Krasnodar Krai, the Chechen Republic and the Primorsky Krai (69, 78, 80 and 88%, respectively). High seroprevalence of Newcastle disease virus in adult poultry in indoor holdings was associated with mass vaccination against the disease. In broiler chickens, post-vaccination antibodies were observed, on average, in 42% of the studied blood serum samples. Antibodies to the Newcastle disease virus were detected in 39% of samples from backyard chickens. Seroprevalence in wild and synanthropic birds was high. The obtained results suggest that the risk of introduction and spread of avian influenza and Newcastle disease in industrial poultry farms and in backyards remains.
Avian mycoplasmosis monitoring in the Russian Federation in 2019
Authors: Menshchikova A. E. , Brundakova T. N. , Volkov M. S. , Irza V. N.
Published: June 2020

Under the conditions of intensive poultry farming and high concentration of poultry in a limited area mycoplasmoses cause significant economic damage to commercial poultry farming. Of greatest interest are respiratory mycoplasmosis and infectious synovitis, the causative agents of which are Mycoplasma gallisepticum and Mycoplasma synoviae, respectively. Considering that both diseases are included in the OIE list of notifiable diseases, it is necessary to perform constant control for their spread. The paper presents an analysis of serological test results for antibodies to mycoplasmosis agents in 2019. Six respiratory mycoplasmosis positive samples – and 129 infectious synovitis positive samples were detected when testing 2,401 chicken serum samples by the enzyme-linked immunosorbent assay (ELISA). The results of monitoring tests of samples received from 31 poultry farms (nine RF Subjects) indicate a decrease in the number of Mycoplasma gallisepticuminfected stocks and stable Mycoplasma synoviae situation. The respiratory mycoplasmosis epidemic situation on indoor poultry farms might have improved due to obtaining the poultry for commercial parent stocks from mycoplasmosis-free sources, better sanitary and hygienic conditions, elimination of the disease provoking factors, and the use of the disease-specific means of prevention in the parent broiler stocks. The infectious synovitis situation remains tense despite the fact that the number of Мycoplasma synoviae-infected farms decreased in comparison with the monitoring results for 2015–2018. Most seropositive stocks were detected on the layer farms (50.0% – in 2019). It seems appropriate to increase the amount of tests to be performed and the number of farms covered by testing in 2020 to more fully present the disease spread situation in commercial poultry farming in Russia.
Developing intrauterine growth curve from two Mayan populations in Guatemala
Authors: Garduno Alexis C , Srikanth Priya , Burket Brent A
Published: June 2020

Background

The purpose of this study was to develop an equation for estimating gestational age using fetal ultrasound measurements specific to women living in the villages of Santiago Atitlán (SA) and San Lucas Tolimán (SLT), which sit in the Guatemalan highlands.

Methods

This study was a prospective observational study of a Guatemalan obstetric population. Cross-sectional design was used to collect baseline maternal characteristics, whereas fetal ultrasound measurements were collected longitudinally. Guatemalan women were continuously enrolled in this study from January 2010 to May 2013 from four clinics based in SA and SLT. Forward selection and mixed-effect modeling techniques were used. Guatemalan data were extrapolated to the Skupski linear mixed effect model, which was developed using ultrasounds obtained in the United States.

Results

894 Guatemalan women enrolled in this study, with 460 of these women had known ultrasound biometrics. In the final model, 285 women contributed 376 ultrasound measurements, where the average number of ultrasound visits was slightly more than one visit.

Conclusions

The intrauterine growth curve generated from these two Mayan populations had notable divergence at later gestation from Skupski curve. This difference may be related to a genetic predisposition, selection bias, environmental factor, or other confounding unidentified variable. Application of this formula longitudinally would help to verify these findings and provide further clarification to the etiology of this possible difference.

Authors: Sahyoun Nadine R. , Sassine Anniebelle , Vaudin Anna , Sakr-Ashour Fayrouz , Ghattas Hala
Published: June 2020

Background

Although we know of the relationship between food insecurity, poor dietary intake and health outcomes, there are limited studies examining the determinants of food insecurity in older adults in developing countries. This study describes the living arrangement and characteristics of protracted Palestinian refugees in Lebanon aged 60 years and older and, the status and determinants of household food insecurity.

Methods

Two surveys, representative of Palestinian refugees in Lebanon (2010 and 2015), were appended and used to examine living arrangement of older adults and household food security. Our final pooled sample included 5412 households and 24,540 individuals. Of these individuals, 10.85% (n=2663) were adults aged 60 years and older, our population of interest. Living arrangement included 1) households with no older adults, 2) multigenerational households that included at least one older adult, 3) older adults living alone, with spouse or with another older person (single households). Food security was collected using two similar questionnaires that were equated and scores were used to classify households into food secure, moderately and severely food insecure. Means and proportions were used to examine household characteristics and sociodemographic and health variables of older adults by living arrangements. Logistic regression tested determinants of food insecurity.

Results

About 27% of older adults lived in single households and of those living alone, 94.3% were women. Overall, poverty was highly prevalent in households (57%) and only 38% of households were food secure. However, poverty and food insecurity were significantly less prevalent in single households (P<0.0001) and these were also the highest recipients of welfare and remittances.

Conclusions

Successful interventions to address poverty and food insecurity will require a better understanding of family structure, interactions within the household, and the role that older adults play within the family.

Published: June 2020

Background

We report the feasibility of using telephones for active surveillance of cancer survival and also present absolute survival rate and its predictors for lung cancer (LC) and gallbladder cancer (GBC) in north India. To date, such information from resource intensive settings is limited.

Methods

Study participants were 530 men and women (259 LC and 271 GBC), registered at ‘Post Graduate Institute of Medical Education and Research’, Chandigarh. Eligible patients were diagnosed with LC or GBC between ages 30 and 69 years during a five-year period from January 1 2010 through December 31 2014, and had a valid telephone number. Information on socio-demographic factors, disease characteristics and treatment status was abstracted from medical records. Participants (or their family/relatives) were followed-up with telephone interviews (March 1 2016 to July 31 2016) to ascertain vital status. Absolute 1-, 3- and 5-year survival rates were calculated using Kaplan-Meier method; weighted Cox Proportional Hazards regression multivariable models were used to evaluate determinants of survival while accounting for losses to follow up.

Results

Over two-thirds of the participants or their families (66.7%) were successfully followed-up via telephone calls. Survival analysis included 354 participants (N=175 LC; 179 GBC) with 326 deaths observed during follow up (N=158 LC; 168 GBC). Absolute survival rates (expressed as percentages with 95% confidence intervals) for LC were 36.7 (29.5-44.7), 10.2 (6.1-15.6) and 2.1 (0.2-8.1) and for GBC 29.0 (22.6-35.8), 5.4 (2.5-9.8) and nil for 1-year, 3-years and 5-years post-diagnosis, respectively; GBC had lower survival rates than LC (P=0.049). Pre-treatment clinical extent of disease was the only significant predictor of survival rates especially for GBC.

Conclusions

Active follow-up of cancer patients through telephone calls is feasible and acceptable in India. Poor survival rates of both LC and GBC underscore the importance of active surveillance by reaching out to family members through practically feasible methods.

Bu amacı gerçekleştirmek için Çukurova Bölgesinde faaliyet gösteren KOBİ’lerde görev yapan 389 yöneticiye, yönetim fonksiyonlarını ölçmeye yönelik, literatürle uyumlu ve mevcut çalışmalardan faydalanılarak hazırlanan anket formları yüz yüze görüşme yöntemi ile uygulanmıştır. Elde edilen verilerin değerlendirilmesinde uygun istatistiki programlar kullanılmıştır. Araştırma sonucunda ölçeğin yönetim fonksiyonları uygulamalarını planlama, organize etme, yürütme ve denetim olmak üzere 4 boyutlu yapıda ölçmede geçerli ve güvenilir olduğu tespit edilmiştir. KOBİ’lerin yürütme ve denetim faaliyetlerini uygulama noktasında ortalamalarının yüksek; planlama ile organize etme faaliyetlerini uygulama noktasında ise ortalamalarının düşük olduğu görülmüştür. Ayrıca yönetim fonksiyonlarının uygulama ortalamaları işletmenin sahiplik, yıldız sayısı ve çalışan sayısına göre anlamlı farklılıklar göstermiştir.

TYS’de ve çoğu sınavda toplam puan becerilere eşit oranda dağıtılmıştır. “Alınan Puanların Denk Geldiği Sertifika Seviyesi” açısından sınavlardaki sertifika seviyesi puan aralıklarının çoğu sınavda birbirinden farklı olduğu saptanmıştır.
Medidas estructurales versus cartografía de inundación en la valoración del riesgo en áreas urbanas: El caso del barranco de las Ovejas (Alicante, España)
Authors: Olcina Cantos Jorge , Oliva Cañizares Antonio
Published: June 2020

La presente investigación demuestra que las medidas no estructurales son más eficaces que las actuaciones estructurales para paliar los efectos de las inundaciones. Se apuesta por la realización de una cartografía de riesgo como principal herramienta de prevención y de defensa de los riesgos naturales, y sobre todo, de las inundaciones, tal como señalan las normativas existentes en materia de ordenación del territorio, suelo y agua. La zona de estudio se localiza en Alicante -barrio de San Gabriel- en la desembocadura del barranco de las Ovejas que ha registrado numerosos episodios de inundación, siendo el más grave el de octubre de 1982. A raíz de esta inundación se canalizó el tramo final del barranco. Para comprobar la eficacia de la canalización se ha realizado una modelización con el mismo caudal registrado en dicho episodio (475 m3/s). Los resultados demuestran que, a pesar de la canalización, el barranco de las Ovejas se desbordaría en diversos puntos a lo largo de su curso. Se presenta una nueva cartografía de riesgo de inundación y una serie de propuestas para reducir el riesgo de inundación y la adaptación al cambio climático, que deben ser atendidas por las administraciones (local, regional y estatal) implicadas.
Geoinformación para la memoria democrática

La finalidad de esta investigación es facilitar la comprensión de la dimensión geográfica mediante el uso de las nuevas tecnologías, mejorar los procesos de enseñanza-aprendizaje y contribuir a la difusión de la memoria democrática. Este último objetivo se facilita mediante el uso de recursos que resulten sugerentes como son las Tecnologías de la Información Geográfica (TIG). La propuesta se fundamenta en el desconocimiento por parte del profesorado en formación de los nuevos recursos geográficos que permiten mejorar los procesos de enseñanza. Para conocer el estado real de la cuestión se han elaborado tres encuestas dirigidas al profesorado en formación de diferentes niveles educativos y tras la pertinente categorización y análisis se ha confirmado la hipótesis inicial. Los resultados obtenidos señalan la necesidad de presentar los nuevos recursos que dispone la Geografía para la comprensión de los contenidos históricos. El conocimiento de las TIG posibilitará la innovación didáctica en la enseñanza de la Geografía y de la Historia.
Modelo de localización óptima de balnearios mediante análisis espacial en la provincia de Buenos Aires. República Argentina
Authors: Laffeuillade Lucía Manuela , Barragán Federico Gastón , Geraldi Alejandra Mabel , Arias Johanna
Published: June 2020

El Ordenamiento Territorial (OT) es un proceso que tiene como objetivo organizar, planificar y gestionar el uso y ocupación del territorio en función de sus características culturales, biofísicas, sociales, económicas y políticas. Se presenta como método planificado para la prevención de los problemas generados por desequilibrios territoriales, conflictos de uso de suelo y/o riesgos naturales. El área de estudio corresponde a la laguna Epecuén, localizada en la provincia de Buenos Aires, República Argentina. Esta área se caracteriza por su dinámica lacustre, la cual varía según atraviese períodos secos o húmedos, produciendo efectos negativos en localidades emplazadas en sus costas. El avance y retroceso del agua dificulta tanto los ingresos –a balnearios, monumentos, ruinas, etc.– como el usufructo de las instalaciones con fines recreativos y de esparcimiento. Producto de esta situación, estudiar las condiciones geográficas del área para establecer sitios óptimos de localización de un balneario que no se vean afectados por esta dinámica, se convirtió en el objetivo general de la investigación. Mediante análisis espacial y técnicas de Evaluación multicriterio se relacionaron variables geográficas para determinar los sitios óptimos planteados en el objetivo. De esta manera se arribó a una matriz que representa las celdas con diferentes grados de aptitud para la localización de un balneario.

TIPOLOGIAS BÍBLICAS
Authors: Lira Turiano Edson José
Published: June 2020

A Tipologia é uma das áreas mais importantes do estudo bíblico, por sua riqueza de
conteúdo e ensinamentos para a igreja. Entretanto, poucos cristãos aprofundam-se neste vasto
campo dos tipos bíblicos. Talvez isto se dê por causa da especulação fantasiosa de alguns, que
exageram na imaginação e criatividade quanto aos tipos bíblicos ou ainda pelo secularismo
que tenta desacreditar o fator sobrenatural das Escrituras Sagradas. Apesar disto, a Tipologia
Bíblica continua sendo um excelente auxílio na compreensão do plano redentor divino e no
conhecimento de nosso Senhor Jesus Cristo. Disse um antigo escritor: “Através dos tipos, na
dispensação passada, Deus estava ensinando aos seus filhos as letras. Nesta dispensação Ele
está ensinando como juntar as letras, as quais organizadas como eles querem, soletram Cristo,
e nada mais que Cristo”.
A study to determine if estrogen (E) is needed to induce de novo progesterone (P) receptors on gamma/delta t cells as evidenced by determining the degree of rise of progesterone induced blocking factor (PIBF) following P exposure in males
Authors: Check J.H. , DiAntonio A. , Check D.L. , Dougherty M.P. , Diantonio G.
Published: June 2020

Purpose: To determine if exposure to progesterone (P) alone without prior estrogen (E) exposure can cause a rise in serum progesterone induced blocking factor (PIBF). Materials and Methods: Male volunteers received IM progesterone 100 mg for seven days. Baseline and day seven levels of serum P and PIBF were taken. PIBF was measured using a non-commercial newly developed ELISA assay. Results: A significant rise in PIBF was found in male volunteers on day seven. Conclusions: The precipitous rise in serum PIBF in males despite a short exposure to progesterone shows that a person does not need E to induce PIBF secretion by gamma/delta T cells. The possibility still exists pending future studies that E may improve PIBF secretion.

The research concerned assessment of the respiratory function and function of the respiratory muscles of women in the third trimester of pregnancy in terms of the level of their physical activity. Using the ATS/ERS assessment criterion, there was no lung ventilation disorder in the studied groups of women. The results of the study indicate that in women who were more active, the values of all measured functional parameters of the respiratory system were higher. In almost all women, irrespective of the level of physical activity, the strength of the inspiratory muscles was found to decrease. The majority of surveyed women undertook physical activity in the form of walking with varying frequency during the week, but only a few of them had undertaken a more intense physical effort. Pregnant women frequently do not undertake more demanding activities due to concerns about the child.

Published: June 2020

This study aims to evaluate the effects of intravenous analgesia using remifentanil combined with Sanyinjiao acupuncture in childbirth. A total of 150 women who delivered their babies naturally were selected. Among these, 100 women willing to undergo labor analgesia and were full-term and with single child, cephalic presentation, and without pregnancy complications were randomly divided into an intravenous injection group (IV) and a combined injection group (CI), while the remainder comprised the control group (C). After the patients entered the active phase of labor, remifentanil was intravenously infused. Patients in group CI were injected with 2 ml of 1% lidocaine into the bilateral Sanyinjiao acupoint. After analgesia began, pain score, mean arterial pressure, and heart rate in group IV and group CI were significantly lower than in group C (p < 0.05). The dose of remifentanil was significantly lower in group CI than in group IV (p < 0.05); however, there was no significant difference in the duration of labor and neonatal score among the three groups (p > 0.05). Neither excessive sedation nor respiratory depression occurred. Sanyinjiao acupoint injection combined with intravenous infusion of remifentanil reduced the amount of opioids and the risk for serious adverse reactions.
Rare case of bizarre leiomyoma in Mayer-Rokitansky-Küster-Hauser Syndrome
Authors: Sun F.Q. , Wang T. , Xu X.H. , Han C. , Jin J.
Published: June 2020

The authors report a case of leiomyoma that developed from an aplastic uterus in a 38-year-old Chinese female with a typical Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. She had normal female secondary sexual characteristics, normal external genitalia with discernible vagina, primary amenorrhea, and infertility with asymptomatic a left adnexal mass. Pelvic MRI showed a mass of 3.7 cm in the left pelvis and a mass of 1.5 × 1.4 × 2.6 cm3 in the right pelvis without a normal functioning uterus and vagina between the bladder and rectum. Laparoscopic exploration showed that the bilateral rudimentary uteri located laterally in the pelvis and they had a constant caudal relationship with their paired ovary. The bilateral fallopian tubes and ovaries were normal. A leiomyoma developed from the left rudimentary uteri. Removal of the left leiomyoma, bilateral rudimentary uteri and fallopian tubes was performed with preservation of bilateral ovaries. The histologic diagnosis showed that the bilateral rudimentary uteri had no clear structures of uterine cavity and endometrium, and the bizarre leiomyoma developed from the left rudimentary uterus without necrosis or mitosis.
