Given the growing rate of revision total knee arthroplasties (TKAs), it is important to understand the potential risk factors associated with postoperative complications. The aim of this study was to determine the role of operative time in postoperative complications in revision TKA. A retrospective cohort study was performed using data from the American College of Surgeons National Surgical Quality Improvement Program database. Patients who had undergone revision TKA between 2007 and 2016 were identified and analyzed based on operative time. The effect of operative time on postoperative complications was examined using multinomial multivariate analysis. A total of 14,769 revision TKA patients were included. On adjusted multivariate analysis, each additional 15 minutes of operative time increased the likelihood of wound complications (odds ratio, 1.023;
P
=.020), postoperative blood transfusion (odds ratio, 1.169;
P
<.001), and extended hospital stay (odds ratio, 1.060;
P
<.001). An increase of 15 minutes of operative time was associated with several postoperative complications. Although operative time is often an uncontrollable factor, surgeons should consider the effect of prolonged operative time on potential complications in the acute postoperative period. [

Published: November 2020

Upper extremity surgeons perform diverse operations, including hand surgery, microsurgery, and shoulder/elbow arthroscopy and arthroplasty. Declining orthopedic reimbursement rates may encourage surgeons to adjust their case mix, favoring a shift toward procedures with higher compensation. To determine whether upper extremity surgeons and hand-fellowship trainees may be financially incentivized to perform more shoulder/elbow procedures than hand procedures in a hospital-based setting, relative value unit (RVU) compensation rates were compared for these 2 fields. Using Centers for Medicare & Medicaid Services–assigned work RVUs (wRVU) and National Surgical Quality Improvement Program operative time data, wRVU compensation rates per minute of operative time were determined for common shoulder/elbow surgeries. Overall nonweighted and weighted wRVU/min averages were calculated for hospital-based shoulder/elbow and hand surgery. A total of 27 shoulder/elbow procedures and 53 hand surgery procedures were analyzed. Nonweighted comparison showed shoulder/elbow surgery had a higher wRVU/min (0.19±0.03 vs 0.14±0.05,
P
<.0001) vs hand surgery. When weighted by procedure frequency, shoulder/elbow surgery also had higher wRVU/min (0.19±0.02 vs 0.15±0.05,
P
<.0001). Fourteen of the 27 shoulder/elbow procedures were compensated either the same wRVU/min or more than all hand procedures except for epicondyle debridement and flexor tendon bursectomy. Almost half of commonly performed shoulder/elbow procedures were compensated at greater rates than most hand procedures in a hospital-based setting. This disproportionate compensation may affect upper extremity surgeons' case mix and motivate providers and hand-fellowship trainees to seek additional training in shoulder arthroplasty and arthroscopy to supplement their practice.

Looking at the Future of Medical Tourism in Asia
Authors: Barat Somjit
Published: November 2020

Despite the popularity of ‘medical tourism' (which involves travel to a foreign destination for primarily medical reasons) as a thriving global industry in recent times, a comprehensive model that emphasizes the decision-making process from the patient's perspective is lacking. In the current paper, the author develops a framework based on the protection motivation theory and designs a robust model, that focuses on how prospective Western patients intend to seek medical treatment in Asian countries. Through an extensive review of extant literature, the author presents five propositions involving key elements of the theoretical framework and makes insightful projections about the future of this flourishing industry. The author believes that this research will immensely benefit the hospitality industry and healthcare practitioners and patients.

Published: November 2020

Saliva have significant roles in maintaining the health of oral cavity. Salivary flow and composition of saliva play a critical role. Saliva also serves as buffer system. Increasing the salivary flow will increase salivary buffer capacity and pH of saliva. Salivary buffer capacity serves to protect the teeth from the acid that comes from food which is formed by acidogenic microorganisms. Milk and dairy are good diet for children that recommended by American Heart Association (AHA). Cheese as one of dairy mild can increase the salivary flow, that help keep the dental hygiene, and prevent bacteria sticking to the teeth. The aim of the study was to identify the effect of cheese and milk consumption on salivary buffer capacity of students aged 10-12 year at Sekolah Dasar Negeri 57 Banda Aceh. Salivary buffer capacity after consume cheese measured after chewing cheese 4 gram about 32 times whereas salivary buffer capacity after consume milk consumption was measured after gargling 25 ml milk 34 times. Salivary buffer capacity measured with Saliva-check buffer (GC). Results of Wilcoxon test showed significant differences (p<0.05) salivary buffer capacity after consumption of milk compared with cheese. Capacity buffer salivary after consumption of cheese higher than milk. In conclusion, cheese and milk consumption have effect on salivary buffer capacity. Salivary buffer capacity after cheese consumption is higher than after milk consumption.
Recycled Polymer Concrete Composite: A Retrospective Review of the Literature and Framework for Thermal Comfort in Homes

Published: November 2020

The aim of this paper is to review the literature on Materials science to identify the current research and to provide direction for future research in thermal properties of the concrete block composite, either with Polyethylene Terephthalate (PET) or Polystyrene (PS), presenting the opportunity to make an important methodological contribution by applying systematic review in three areas of Materials science: Composites, Building Materials, as well as Testing and Evaluation of Materials. This is a growing interdisciplinary field since there are no current comparative papers addressing both PET and PS in the same research for concrete composites. Papers investigating to what extent, what type and how academic publications are integrated on the analysis of the characteristics of the two recycled polymers (PET and PS), to improve the thermal properties of the concrete block and contribute to the research of sustainable thermal comfort in homes. They were reviewed, keywords were identified within a framework of composites, building materials, as well as testing and evaluation of materials, and a lexical analysis of the papers was conducted. The results of current research show that both forms of recycling (PS and PET), combined with concrete, have sustainability in thermal comfort. The analysis reveals that previous research has focused on PET-Concrete (i.e., concrete-PET polymer composite) since it is more viable, due to its large amount of recycling. While this has benefited home builders in their ability to respond with some thermal comfort with higher construction efficiency, it also clarifies that there has been research done on PS-Concrete (i.e., concrete-PS polymer composite), presenting greater thermal comfort, because it has lower thermal conductivity. This finding suggests the need for further research within this narrow field, with absence of data, since most prescriptive recommendations have not been tested and lack practical applications, which is why the need for more empirical and experimental studies are identified. Based on the novelty of the PET or PS recycling concepts, we highlight the need of better collaboration between academic disciplines, such as engineering and architecture to provide better experimental evidence for recycling of polymers, including empirical approaches for the different types of composites and aggregate distributions, which can be made with concrete to improve thermal insulation performance and energy savings for manufacturers.
Ultimate Strength Prediction of Fibrous Composites only upon Independently Measured Constituent Properties
Authors: Zhu Xiao Jun , Qu Hon Gyi , Xin Ke Hao , Qiu Xiang Ru , Chen Ju Wei
Published: November 2020

This study presents an accurate and easy-to-use micromechanical model to predict the ultimate strength of unidirectional polymer composites under an arbitrary load condition only upon independently measured constituent properties. In this model, the micromechanical method based on generalized model of cells (GMC), which effectively predict the nonlinear deformation of unidirectional composites, is used to analyze the repeating unit cells of composites. At the same time, a unified plastic theory (i.e. modified Ramaswamy-Stouffer model) is incorporated into the GMC's analytical framework to describe viscoplastic behaviors of matrix phase. Additionally, because of the stress concentration effect which causes the difference between the matrix in-situ and original strength behaviors, a stress concentration factor is introduced in order to utilize the measured constituent properties directly. The prediction results with SCF match better with the experimental results than the prediction results without SCF. In addition, the prediction results show that the presence of thermal residual stress and material plastic effects generally has important influence on the strength prediction of a composite.
Simple Implementation of Asymptotic Homogenization Method for Periodic Composite Materials
Authors: Yang S. S. , Gao T. , Shen Cheng
Published: November 2020

In this paper, a simple implementation method of Asymptotic homogenization (AH) method is developed with the aid of commercial FEM software as a tool box. Then, abundant structural elements (like beam, shell and solid elements) in commercial software can be used to model unit cell with various complex substructures of periodic materials, while simultaneously reducing the model to a small scale with less amount of calculation. During the implementation, a set of simple displacement boundary conditions are assumed for unit cell, and final effective elastic constant can be directly calculated after several static analysis. Two representative examples of applications are chosen and discussed to verify the validity and applicability of the new implementation method by comparing with other methods. The proposed method is expected to become an effective benchmark for assessing other homogenization theories and extended to other homogenization problems (such as thermal expansion coefficient) in the future.

Published: November 2020

IFN regulatory factor 3 (IRF3) is a transcription factor that is activated by multiple pattern-recognition receptors. We demonstrated previously that IRF3 plays a detrimental role in a severe mouse model of sepsis, induced by cecal ligation and puncture. In this study, we found that IRF3–knockout (KO) mice were greatly protected from sepsis in a clinically relevant version of the cecal ligation and puncture model incorporating crystalloid fluids and antibiotics, exhibiting improved survival, reduced disease score, lower levels of serum cytokines, and improved phagocytic function relative to wild-type (WT) mice. Computational modeling revealed that the overall complexity of the systemic inflammatory/immune network was similar in IRF3-KO versus WT septic mice, although the tempo of connectivity differed. Furthermore, the mediators driving the network differed: TNF-α, IL-1β, and IL-6 predominated in WT mice, whereas MCP-1 and IL-6 predominated in IRF3-KO mice. Network analysis also suggested differential IL-6–related inflammatory programs in WT versus IRF3-KO mice. We created bone marrow chimeras to test the role of IRF3 within leukocytes versus stroma. Surprisingly, chimeras with IRF3-KO bone marrow showed little protection from sepsis, whereas chimeras with IRF3-KO stroma showed a substantial degree of protection. We found that WT and IRF3-KO macrophages had a similar capacity to produce IL-6 and phagocytose bacteria in vitro. Adoptive transfer experiments demonstrated that the genotype of the host environment affected the capacity of monocytes to produce IL-6 during sepsis. Thus, IRF3 acts principally within the stromal compartment to exacerbate sepsis pathogenesis via differential impacts on IL-6–related inflammatory programs.
Deficiency of the Intramembrane Protease SPPL2a Alters Antimycobacterial Cytokine Responses of Dendritic Cells

Published: November 2020

Signal peptide peptidase–like 2a (SPPL2a) is an aspartyl intramembrane protease essential for degradation of the invariant chain CD74. In humans, absence of SPPL2a leads to Mendelian susceptibility to mycobacterial disease, which is attributed to a loss of the dendritic cell (DC) subset conventional DC2. In this study, we confirm depletion of conventional DC2 in lymphatic tissues of SPPL2a−/− mice and demonstrate dependence on CD74 using SPPL2a−/− CD74−/− mice. Upon contact with mycobacteria, SPPL2a−/− bone marrow–derived DCs show enhanced secretion of IL-1β, whereas production of IL-10 and IFN-β is reduced. These effects correlated with modulated responses upon selective stimulation of the pattern recognition receptors TLR4 and Dectin-1. In SPPL2a−/− bone marrow–derived DCs, Dectin-1 is redistributed to endosomal compartments. Thus, SPPL2a deficiency alters pattern recognition receptor pathways in a CD74-dependent way, shifting the balance from anti- to proinflammatory cytokines in antimycobacterial responses. We propose that in addition to the DC reduction, this altered DC functionality contributes to Mendelian susceptibility to mycobacterial disease upon SPPL2a deficiency.
Brain death: understanding the organism as a whole
Authors: Bonelli J. , Prat E.H. , Auner N. , Bonelli R.
Published: November 2020

Since intensive care medicine enables us to maintain blood circulation and respiration artificially for some time, the usual criteria for death, such as cardiac arrest and cessation of respiration, are not applicable in all cases. Thus, the irreversible breakdown of the brain functions have come to be accepted as the most prominent factor for the occurence of death. This criterion is linked primarily to the disintegration of the organism as a whole. Yet the controversy surrounding the moment when a man can be declared dead or alive has not yet been resolved. The decisive weak point in this controversial discussion seems to be that the notion of the “organism as a whole” is inadequately defined. The aim of this study is to fill this void. Thus, at a first approximation, a rough definition of the “organism as a whole” is given. In a second step we turn to examine the empirical evidence related to the question of whether this attribute is possessed or not by a human body with an irreparably damaged brain.

For the characterization of life and death, as related to our question, it is important to distingnish between derivated biological life (isolatedly living cells or organs, cell cultures, heart-lung-compound) and a living being. For this distinction the criteria of completion, indivisibility, auto-finality and identity have been considered. If these are missing a living being does not exist. Then a man is no longer a living man, he is dead.

In brain-dead body one finds a number of signs of life such as heartbeat, metabolism, growth of cells, regeneration an so forth. These signs of life, however, are not signs of an organsim as a whole but signs of a physiological combination of organs whose parts - directed from the outside - are dependent on each other. The brain-dead body lacks, however, the four criteria of a living being. Thus it is no longer a living man. It is a purely derivated biological life. If we regard the brain-dead body indirectly by considering the status of the brain itself and its functions we can say that the brain is the constitutive foundation (the guarantor) for the identity and completion of an individual as a whole. With the loss of the brain this wholeness is lost. The man is dead.

The Universal Declaration of Human Rights in medical-ethical perspective
Authors: Eijk Willem J.
Published: November 2020

Notwithstanding its impressive achievements in combating crimes against humanity, the Universal Declaration of Human Rights offers no sufficient basis for medical ethics. It does not provide a clear definition of the human being who is subject of human rights, thus giving room for philosophical anthropologies according to which fetuses or neonates are no human persons yet or at most ‘marginal persons’. Because the Declaration likewise fails to define the concept of right, it can be interpreted from the perspective of classical theories of right as well as from that of the ‘choice theory of right’. If, as the last states, the right to life would include the right to dispose of it, the Declaration could serve to defend euthanasia, assisted suicide and manipulative medical and surgical interventions as well.

Authors: Doğan Selami , Doğan Nuray , Yılmazer Tevfik Tanju , Öngel Kurtuluş
Published: November 2020

Objective: Approximately 80% of women in reproductive age experience some premenstrual ‎phase-related changes in the menstrual cycle. We aimed to determine the prevalence of premenstrual syndrome (PMS) and ‎premenstrual dysphoric disorder symptom frequency among women aged 15-49 years in a family practice catchment area.

Material and Methods: A cross-sectional study was conducted in the women registered to a family practice center in İzmir Bayraklı. Out of 522 women at the age of 15-49 years, 198 participants filled the Premenstrual Assessment Form (PAF) and answered demographic questions. The main outcome measures were the presence of “premenstrual ‎symptoms” and “premenstrual syndrome”.

Results: The mean age, waist circumference and BMI of the women were 29.3±9.1 years, 80.4±13.2 ‎cm and 25.2±5.1 kg/m2, respectively. Of the participants, 68.2% (n=131) were single and 60.4% ‎‎ (n=116) were housewives. Premenstrual syndrome (PMS) was present in all the women involved in the study. Of ‎these, 3.6% were evaluated as premenstrual dysphoric disorder (PMDD). None of the ‎independent variables in the study revealed as risk factors for PMDD (p>0.05). Mean PAF scores were ‎2.22±0.90‎. There was no correlation between PAF scores and the studied variables except for waist ‎circumference (r = -0.17; p = 0.02). The sociodemographic variables ‎were not related with PMS (p> 0.05).‎

Conclusions: Training and counseling on the causes and ‎symptoms of PMS should be provided to women, particularly in primary health care facilities, and in-service trainings should be ‎conducted to provide information to the staff working in family practice centers.‎

Isolation of Keratinolytic Microorganism
Streptomyces chartreusis strain ISP 5085 from the
Soil Sample: Characterization, Degradation and
Microbial Identification using 16S rDNA Region
Authors: Jitendra Nayak and Bhikhu More
Published: November 2020

Keratinolytic microorganisms have a broad significance in feather waste degradation and it can be used
for advancement of livestock feed and production of protein hydrolysates. Production of keratin into the
environment in different forms is very high which leads to setback for its degradation. An approach for
degradation of keratin based wastes through potential microorganism with higher efficiency can be attained.
The study shows that maximum DFD% i.e. Degree of Feather (keratin) Degradation, through the isolates is
achieved, when nutrient medium is kept at temperature 30 °C and pH-8.5 supplemented with dehydrated
powdered form of chicken feathers as keratin source for 72 h – 120 h. Chicken feathers acts as a better
substrate and source of keratin content. A molecular approach was necessary therefore; phylogenetic trees of
the isolate were constructed with neighbour-joining method through the Microbial Identification using 16S
rDNA Region, which showed that sequence exhibited a high level of homology with Streptomyces chartreusis
strain ISP 5085. The present study deals with identification of isolates that play a significant role in the
degradation of chicken feather waste as well as keratin degradation ability of the isolates and optimum
conditions required for it.

Assessment of Renal Functions in Infants with Acute Gastroenteritis
and Dehydration
Authors: S sandeep
Published: November 2020

Background: Acute gastroenteritis is a very common illness in
neonates and infants and it is one of the important causes of
morbidity and mortality in third world countries. Most of the
complications are due to excessive fluid loss and electrolyte
imbalance adversely affecting kidney functions. Renal failure
is one of the critical causes of morbidity in these children.
Aim: We in the present study tried to evaluate the renal
functions in infants with acute gastroenteritis reporting to our
tertiary care teaching Hospital.
Methods: This cross-sectional prospective study was
performed on n=100 infants with gastroenteritis admitted into
the Emergency service room of Prathima Institute of Medical
Sciences and Hospital, Naganoor, Karimnagar. The degree
Dehydration was assessed both clinically and hematologically.
Blood samples for estimation of leucocyte count, Urea,
Creatinine, and electrolyte estimation were drawn initially on
admission and subsequently, blood culture, urine culture, and
radiologic procedures were undertaken whenever indicated.
Result: There are 16 cases with Blood urea more than 84 mg,
indicating 16% of renal failure in the total number of cases
studied, taking blood urea more than 20 mg as the criterion.
But considering urinary output there are 18 cases with urinary
output less than 300 ml/1.73 M 2 /24-hours. All these cases
show creatinine values of more than 1.5 mg%. The glomerular
filtration rate is decreasing as the severity of dehydration is
increasing and fractional excretion of Sodium is diminishing
with an increase in the severity of dehydration.
Conclusion: The biochemical parameters like serum creatinine,
blood urea, the urinary volume must be routinely in all cases
of dehydration along with urinary indices like FeNa and R.F.I
to detect the early onset of acute tubular necrosis. Prompt
administration of intravenous fluids in acute gastroenteritis
will go a long way in minimizing the mortality and morbidity
among the infants

Published: November 2020

Background: Ectopic pregnancy is not an uncommon condition
and is potentially a life- threatening emergency. There is a rising
trend in incidence which necessitates the gynecologists to have
comprehensive knowledge about the disease.
Aim of the study: To determine the incidence, risk factors,
clinical features and management.
Materials and method: This study is conducted in Department
of Obstetrics and Gynecology of PIMS, Karimnagar. It is a
retrospective descriptive study on patients who presented to
our department with clinical features of ectopic pregnancy and
later confirmed with intraoperative findings or ultrasound, in
the 3-year period from January 2017 to January 2020.
Result: A Total of 34 patients were diagnosed to have ectopic
pregnancy with an incidence of 1in 114 deliveries. The cause
of ectopic pregnancy was dilatation and curettage in 11.8%
and PID, infertility, prior tubal surgery, previous abortions and
OCP usage each contributes by 5.9%. Surgical treatment with
salpingectomy was done in majority of the cases and medical
management in 3 patients. Blood transfusions were given in
38.2% of cases. Postoperative period is uneventful in all the
cases.
Conclusion: Gynecologists should have comprehensive
knowledge about the clinical presentation and risk factors of
EP. If suspected clinically, encouraging women to undergo early
ultrasonography allows early detection of EP and can be
managed medically or fertility sparing surgical procedures

Las variables evaluadas fueron: días de germinación, número de tallos, ancho de hoja, largo de hoja y diámetro de raíz. La influencia de la composta como mejorador del sustrato tuvo un efecto positivo en las variables agronómicas evaluadas  en  todos  los  cultivos,  así  como  en  la retención  de  agua  en  el  sustrato.  La tendencia en los días de germinación no tuvo diferencias entre el suelo testigo y suelo más composta. En todos los cultivos la Hi2 comprueba que la variable agronómica estudiada en suelo testigo es diferente al del suelo más composta. Para las variables hojas verdaderas, ancho y largo de hoja, número de individuos en y diámetro de raíz exclusivamente en rábano el suelo más composta mostraron un crecimiento sobresaliente en comparación con el tratamiento de suelo testigo en sus cuatro repeticiones.

Con la finalidad de establecer un protocolo de desinfección y multiplicación in vitro para la obtención de plántulas de Erythrina americana Miller, se evaluaron dos diferentes desinfectantes etanol e hipoclorito de sodio en concentraciones porcentuales de 35, 45, 55, 65 y 70 (v/v) y 20, 25, 30, 35 y 40 respectivamente, con tiempos de inmersión de 5, 10, 15, 20 y 25 minutos para ambos; se utilizaron segmentos nodales de 2.0 cm de longitud. El medio de cultivo utilizado fue Murashige y Skoog (MS) adicionado con 3% de sacarosa, vitaminas y bencilamino purina (BAP) 0.5 mgL-1 y Ácido indolbutírico (AIB) 0.1 mgL-1. Los resultados

mostraron que la inmersión de los segmentos nodales en elevadas concentraciones y tiempos prolongados registraron el 100% de muerte por necrosis de los tejidos, sin embargo, con las soluciones de etanol al 35 % (v/v) e hipoclorito de sodio al 30% (v/v) con un tiempo de cinco minutos de inmersión, controlaron la contaminación fúngica o bacteriana, sin afectar la viabilidad de los segmentos nodales. Con la concentración de BAP 0.5 mgL-1 y AIB 0.1 mgL-1, se estimuló una yema durante la etapa de multiplicación, lo cual indicó, que es necesario hacer más combinaciones de reguladores del crecimiento a fin de obtener la concentración óptima  que  estimulen  el  mayor  número  de  yemas  posibles.  Los  resultados  obtenidos permitieron comprobar que micropropagar esta especie es una alternativa viable para su comercialización, conservación y reforestación de zonas degradas.

Published: November 2020

El trabajo tuvo como objetivo evaluar la eficacia in vitro de diferentes bactericidas para el control de Erwinia sp. aislada en plantas de violeta africana (Saintpaulia ionantha) procedentes de un invernadero en la localidad de Tenango de las Flores, Huachinango, Puebla. Después de realizar los postulados de Koch, el agente causal del tizón bacteriano fue identificado como Erwinia sp. Este patógeno daña principalmente en las hojas y puede llegar a destruir toda la planta ya que produce grandes cantidades de enzimas pectolíticas. En el bioensayo de laboratorio se utilizó un diseño completamente al azar con cinco repeticiones y siete tratamientos, Oxicrop, Agri-Mycin® 100, Bactrol® 2x, Hidrobacter®, Terramicina® Agrícola 5%, Final Bacter y Agrobacter®, adicionándose además un testigo sin bactericida y evaluando el efecto de halos de inhibición producidos en un medio de agar de soya tripticaseína. El análisis estadístico indico diferencias estadísticamente significativas entre los tratamientos, a las 48 horas de haber formado halos de inhibición por cada tratamiento (ANOVA p < =0.05). La prueba de comparación de medias, mostro la existencia de diferencias significativas en lo que respecta a los halos de inhibición causados en cada uno de los tratamientos en estudio, siendo el tratamiento 4 (Hidrobacter®), el que presentó el mayor halo de inhibición siendo estadísticamente similar a los tratamientos 1 (Oxicrop) y 6 (Final Bacter). El tratamiento 2 (Agri-Mycin® 100) mostró el menor halo de inhibición lo que significa que el aislado bacteriano mostró tolerancia al efecto de los ingredientes activos (estreptomicina y oxitetraciclina) contenidos en el producto comercial y no sería recomendable su uso en campo a las dosis recomendadas.

Uno de los problemas que afecta los planes de cultivo y expansión de este cultivo en el mundo es su susceptibilidad a plagas y enfermedades.  Fusarium oxysporum f. sp. vanillae como el principal agente causal más devastador y causante de la enfermedad de pudrición de tallo y raíz. A pesar de ser México centro de origen y domesticación de la vainilla actualmente no se cuentan con materiales genéticos resistentes a este patógeno, ni con métodos de control efectivos a esta enfermedad. Por tal razón se planteó la presente investigación con el objetivo de rescatar esquejes de Vanilla planifolia Andrews de un cultivo bajo malla sombra afectado por el hongo. El rescate de los esquejes de Vanilla planifolia Andrews atacada por el hongo Fusarium oxyporum vanillae consistió en la implementación de prácticas de manejo y aplicaciones de Fungicidas químicos, lo que en su conjunto contribuyó a que se recuperaran el 100 % de los esquejes rescatados esperando que con los resultados de este estudio sirvan de base para el establecimiento de una guía técnica de manejo integrado del cultivo y apoyar a los productores para resolver la afectación del Fusarium que tan comúnmente se presenta en este cultivo.

El objetivo del presente trabajo es mostrar los resultados de toros con postitis que se les practicó Técnica Modificada de Postioplastia como manejo quirúrgico de esta patología. Se realizó un estudio de tipo descriptivo no probabilístico en toros reproductivamente activos que presentaron postitis crónica ulcerativa. Los casos clínico-quirúrgicos se presentaron en diferentes ranchos de la zona sur de Veracruz. Los pacientes fueron 10 toros cebús de los cuales 7 eran de la raza brahmán, 1 indubrasil y 2 Sardo Negro, con buena condición corporal y con postitis crónica ulcerativa. Ninguno de los animales había recibido tratamiento quirúrgico. Se aplicó xilacina al 2 % a la dosis de 0,1 mg/kg de peso vivo como tranquilizante por vía intramuscular. Posteriormente, para la anestesia, se infiltró clorhidrato de lidocaína al 2 % a dosis de 1 ml/cm3 de tejido en la base del prepucio. Una vez tranquilizado el paciente y realizadas las maniobras de derribo, se hizo lavado y evaluación detallada de la lesión. Se realizó una incisión en el limbo mucocutáneo y no en piel para reducir las posibilidades de fimosis cicatrizal. Se ligaron los vasos de gran calibre con puntos de transfixión con material absorbible acidó poliglicólico del calibre 0. Para la hemostasia de los vasos pequeños fue suficiente el pinzamiento y torsión. La divulsión se realiza en 360° hasta conseguir el desprendimiento de todo el tejido afectado incluyendo la mucosa prepucial dañada. Una vez practicada la correcta hermostasis se procedió sujetar la mucosa con pinzas de goma para evitar la retracción, así mismo se le colocaron 4 puntos de forma cardinal con sutura de  nylon monofilico para expandir la mucosa y poder suturarla a la piel, esos mismo puntos de sujeción se fijaron con punto de cirujano y posteriormente se colocaran 4 puntos entre ellos. Los 10 toros operados con la técnica descrita tuvieron recuperación en un período de 90 días posoperatorio en promedio, dos de ellos tuvieron complicación de estenosis cicatrizal.  Se concluye que la técnica quirúrgica empleada en este estudio tuvo resultados favorables. Se considera que si el posoperatorio no se lleva correctamente trasciende seriamente en el éxito o fracaso de esta cirugía.
Un año de observaciones meteorológicas en Loma Bonita, Oax., México; una referencia climatológica para su industria agropecuaria

A partir de los datos de una estación meteorológica personal se analizaron distintos parámetros atmosféricos en Loma Bonita, Oax., durante el año 2019. Los resultados señalan un rango térmico medio anual de 14.7 a 41.9°C y una sensación térmica que va de 14.7 a 57°C.  La menor incidencia de vientos alisios propició una disminución del 44%  en  la precipitación total con respecto al valor normal; contrariamente, las temperaturas máximas, mínimas y medias fueron claramente mayores a los valores regulares.   Es probable que los cambios observados sean producto de un posible cambio en la climatología de la ciudad, por lo que las actividades agropecuarias de la zona deberían considerar los patrones actuales de temperatura y precipitación.   Al mismo tiempo, la salud de la población debe protegerse de los altos niveles de insolación y de radiación UV que se han registrado.
