Night-time blood pressure dipping, but not 24-h blood pressure level, is linked to increased 24-h ocular volume slope

ABSTRACT Purpose: This study investigated the relationship between blood pressure and intraocular pressure in treatmentnaive, non-glaucoma patients with different blood pressure statuses, focusing on the 24-h ocular volume and nocturnal blood pressure decline. Methods: Treatment-naive, non-glaucoma patients undergoing hypertension evaluation were enrolled as study participants. Simultaneous 24-h ambulatory blood pressure measurement and 24-h ocular volume recording with a contact lens sensor. We also compared ocular volume curve parameters between normotensive and hypertensive patients, as well as between those with and without nocturnal blood pressure decline. Results: A total of 21 patients, including 7 normotensive and 14 treatment-naive hypertensive individuals, were included in the study. of them, 11 were dippers and 10 were non-dippers. No significant difference in the 24-h ocular volume slope was observed between the hypertensive and normotensive patients (p=0.284). However, dippers had a significantly higher 24-h ocular volume slope (p=0.004) and nocturnal contact lens sensor output (p=0.041) than non-dippers. Conclusion: Nocturnal blood pressure decline, rather than the blood pressure level, is associated with the increased 24-h ocular volume slope and nocturnal ocular volume. Further studies are required to determine whether the acceleration of glaucoma progression in dippers is primarily due to low blood pressure, high intraocular pressure, or a combination of both.

Development of nerves and vessels in the penis during the human fetal period

ABSTRACT Introduction: Although nerves and vessels of the penis play important role in erection, there are few studies on their development in human fetus. Therefore, the objective of the present study is to analyze, quantitatively, in the corpora cavernosa and corpus spongiosum, the development of the nerves and vessels in the fetal penis at different gestational ages. Material and Methods: Fifty-six fresh, macroscopically normal human fetuses aged from 13 to 36 weeks post-conception (WPC) were used. Gestational age was determined by the foot length criterion. Penises were immediately fixed in 10% formalin, and routinely processed for paraffin embedding, after which tissue sections from the mid-shaft were obtained. We used immunohistochemical staining to analyze the nerves and vessels in the corpus cavernous and in the corpus spongiosum. These elements were identified and quantified as percentage by using the Image-J software. Results: The quantitative analysis showed that the percentage of nerves varied from 3.03% to 20.35% in the corpora cavernosa and from 1.89% to 23.88% in the corpus spongiosum. The linear regression analysis indicated that nerves growth (incidence) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.9421, p<0.0001) and (r2=0.9312, p<0.0001), respectively, during the whole fetal period studied. Also, the quantitative analysis showed that the percentage of vessels varies from 2.96% to 12.86% in the corpora cavernosa and from 3.62% to 14.85% in the corpus spongiosum. The linear regression analysis indicated that vessels growth (appearance) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.8722, p<0.0001) and (r2=0.8218, p<0.0001), respectively, during the whole fetal period studied. In addition, the linear regression analysis demonstrated a more intense growth rate of nerves in the corpus spongiosum during the 2nd trimester of gestation, when compared with nerves in the corpora cavernosa. In addition, the linear regression analysis demonstrated a more intense growth rate of vessels in the corpus spongiosum when compared with the corpora cavernosa, during the whole fetal period studied. Conclusions: In the fetal period, the human penis undergoes major developmental changes, notably in the content and distribution of nerves and vessels. We found strong correlation between nerves and vessels growth (amount) with fetal age, both in the corpora cavernosa and corpus spongiosum. There is significant greater proportional number of nerves than vessels during the whole fetal period studied. Also, nerves and vessels grow in a more intense rate than that of the corpora cavernosa and corpus spongiosum areas.

Abstract: Antithrombotics are drugs used to prevent the formation of blood clots, also known as thrombi. These clots can cause serious health problems, such as heart attacks or strokes. Different types of antithrombotics, such as antiplatelets and anticoagulants, are analyzed and their mechanisms of action are discussed. Additionally, the benefits and risks associated with the use of antithrombotics are examined. On the one hand, these drugs can reduce the risk of thrombotic events, which may be especially beneficial in patients with high-risk conditions, such as those who have suffered a heart attack or who have atrial fibrillation. On the other hand, the possible side effects of antithrombotics, such as the increased risk of bleeding, are also discussed and guidelines for their safe use in different clinical scenarios are provided. Additionally, monitoring and dose adjustment strategies for these medications are addressed to ensure their effectiveness and safety in patients.

Prevalencia y caracterización de la anemia en cirugía electiva en un Hospital Universitario

está disponible en el texto completo

Introduction: Anemia is a highly prevalent disorder. Preoperative anemia is associated with higher mortality, more complications, longer hospital stays, and higher healthcare costs. Red blood cell transfusion (RBC) does not improve these outcomes. The World Health Organization recommends implementing Patient Blood Management (PBM) programmes, as they can improve these clinical outcomes, reduce unnecessary RBC transfusions, and save costs. Despite compelling evidence, the implementation of these measures has yet to be effectively achieved. The objective of this study is to conduct a situational analysis to raise awareness about this issue and encourage the implementation of these measures. Methodology: An observational, longitudinal, retrospective cohort study was conducted at a single center. All patients undergoing elective surgery from 01/01/2022 to 01/04/2022 at the Hospital de Clínicas were included. Exclusion criteria: absence of a complete blood count in the three months prior to surgery and refusal to participate in the study. Results: A total of 329 surgeries were analyzed. 52 out of 100 procedures were performed on patients with anemia. A statistically significant association was found between preoperative anemia and receiving RBC transfusion during hospitalization. OR 11.746 (4.518 - 30.540). Anemia and RBC transfusions significantly prolonged hospital stay. Length of hospitalization based on patient condition: No anemia: 10.1 ± 1.1 days, with anemia: 27.2 ± 2.3 days. Value of p < 0.001. Non-transfused: 14.5 ± 1.3 days, transfused: 41.8 ± 4.4 days. Value of p < 0.001. Only 49 (28.6%) of the 171 patients with anemia had iron metabolism assessed before surgery. Among the 140 patients with Hb < 12 g/dL undergoing surgeries with non-insignificant bleeding, only 4 received specific treatment to optimize Hb. A total of 185 units of red blood cells (RBC) were administered during hospitalization. 49 to unstable patients (intraoperative or acute hemorrhage) and 136 to stable patients. From the analysis of the latter group, 42.5% of the patients received 3 or more RBC units. The average pre-transfusion hemoglobin was 7.0 ± 0.1. A statistically significant association was found between receiving RBC units and dying during hospitalization. OR 17.182 (3.360 - 87.872). Conclusiones: A situational analysis was conducted, revealing a high prevalence of preoperative anemia, scarce study and treatment of anemia before surgeries, and an excessive amount of blood transfusions received by some patients. This work establishes the need to implement Patient Blood Management programs to reduce the prevalence of preoperative anemia and improve our transfusion practices. It also sets a comparative framework to evaluate the progress of these measures and indicates possible indicators to assess the benefits of their implementation.

Introdução : A anemia é um distúrbio altamente prevalente. A anemia pré-operatória está associada a maior mortalidade, mais complicações, tempo prolongado de internação e maiores custos de saúde. A transfusão de glóbulos vermelhos (TGV) não melhora esses resultados. A Organização Mundial da Saúde recomenda a implementação de medidas de Gerenciamento de Sangue do Paciente (GSP), pois permitem melhorar esses resultados clínicos, reduzir TGV desnecessárias e economizar custos. Apesar da evidência contundente, a implementação dessas medidas ainda está aquém de ser efetivada. O objetivo deste trabalho é realizar uma análise da situação para conscientizar sobre o problema e incentivar a implementação dessas medidas. Metodologia: Foi realizado um estudo observacional, longitudinal, retrospectivo de coorte histórica, unicêntrico. Foram incluídos todos os pacientes submetidos a cirurgias de coordenação de 01/01/2022 a 01/04/2022 no Hospital de Clínicas. Critérios de exclusão: ausência de hemograma nos três meses anteriores à cirurgia e recusa em participar do estudo. Resultados: Foram analisadas um total de 329 cirurgias. 52 a cada 100 procedimentos foram realizados em pacientes com anemia. Foi encontrada uma associação estatisticamente significativa entre a anemia pré-operatória e a recepção de TGR durante a internação. OR 11,746 (4,518 - 30,540). A anemia e as TGR prolongaram significativamente a internação hospitalar. Dias de internação em função da condição do paciente: Sem anemia: 10,1 ± 1,1 dias, com anemia: 27,2 ± 2,3 dias. Valor p < 0,001. Não transfundidos: 14,5 ± 1,3 dias, transfundidos: 41,8 ± 4,4 dias. Valor p < 0,001. Apenas 49 (28,6%) dos 171 pacientes com anemia tinham metabolismo do ferro antes da cirurgia. Dos 140 pacientes com Hb < 12 mg/dL submetidos a cirurgias com sangramento não insignificante, 4 receberam tratamento específico para otimizar a Hb. Foram administradas um total de 185 unidades de glóbulos vermelhos (UGV) durante a internação. 49 em pacientes instáveis (intraoperatório ou hemorragia aguda) e 136 em pacientes estáveis. Da análise desses últimos, 42,5% dos pacientes receberam 3 ou mais UGV. A hemoglobina pré-transfusional média foi de 7,0 ± 0,1. Foi encontrada uma associação estatisticamente significativa entre receber UGV e falecer durante a internação. OR 17,182 (3,360 - 87,872). Conclusões: Foi realizado uma análise da situação na qual foi observada uma elevada prevalência de anemia pré-operatória, um estudo e tratamento escasso da anemia antes das cirurgias e uma quantidade excessiva de UGV recebidas por alguns pacientes. Este trabalho estabelece a necessidade de implementar programas de Gerenciamento de Sangue do Paciente para reduzir a prevalência de anemia pré-operatória e melhorar nossas práticas transfusionais. Além disso, estabelece um quadro comparativo para avaliar o progresso dessas medidas e aponta possíveis indicadores para avaliar os benefícios de sua implementação.

Effect of anisodamine on regional cerebral blood flow in patients with dizziness: Arandomized single-blind controlled trial / Efecto de la anisodamina en el flujo sanguíneo cerebral regional en pacientes con mareos: un ensayo controlado aleatorizado de unsolo ciego

This study aimed to evaluate the effect of anisodamine on regional cerebral blood flow (rCBF) and associated dizziness. 150 patients with dizziness induced by low rCBF were divided randomly into groups A (n = 60; anisodamine), P (n = 60; alprostadil), and C (n = 30; normal saline). rCBF and dizziness severity were evaluated. After treatment, rCBF values increased both in groups A and P. The subjective symptom of dizziness improved in 55 (91.7%) patients with the DHI score decreasing from 65.9 ± 5.4 to 23.1 ± 7.4 in group A, and the symptom improved in 37 (61.7%) patients with the DHI score decreasing from 66.8 ± 6.2 to 43.8 ± 8.6 in group P. The difference in DHI score and rCBF values in group A was more significant than that in group P. Anisodamine could increase rCBF and alleviate symptoms of dizziness more effectively than alprostadil.

Este estudio tuvo como objetivo evaluar el efecto de la anisodamina en el flujo sanguíneo cerebral regional (rCBF) y los mareos asociados. 150 pacientes con mareos inducidos por un bajo rCBF fueron divididos aleatoriamente en los grupos A (n = 60; anisodamina), P (n = 60; alprostadil) y C (n = 30; solución salina normal). Se evaluaron el rCBF y la gravedad de los mareos. Después del tratamiento, los valores de rCBF aumentaron tanto en los grupos A como en P. El síntoma subjetivo de mareo mejoró en 55 (91.7%) pacientes con una disminución de la puntuación DHI de 65.9 ± 5.4 a 23.1 ± 7.4 en el grupo A, y el síntoma mejoró en 37 (61.7%)pacientes con una disminución de la puntuación DHI de 66.8 ± 6.2 a 43.8 ± 8.6 en el grupo P. La diferencia en la puntuación DHI y los valores de rCBF en el grupo A fue más significativa que en el grupo P. La anisodamina podría aumentar el rCBF y aliviar los síntomas de mareo de manera más efectiva que el alprostadil.

Hipertensión arterial nocturna: análisis según su gravedad / Nocturnal Hypertension: Analysis According to its Severity

RESUMEN Introducción: En el diagnóstico y seguimiento de la hipertensión arterial (HTA) la mayoría de las guías de práctica recomiendan el monitoreo ambulatorio de la presión arterial (MAPA). En este sentido, existe cada vez más evidencia que respalda la superioridad de la hipertensión arterial nocturna (HTAN) como predictor de eventos cardiovasculares. Se sabe poco sobre la relación con los eventos cardiovasculares según la gravedad de la HTAN. Además, no está claro a partir de qué valor de presión arterial nocturna comienza a aumentar el riesgo. Objetivos: Conocer si la presencia de HTAN y sus niveles de gravedad se asocian con resultados cardiovasculares adversos durante el seguimiento. Material y métodos: Estudio observacional. Realizamos un análisis de los datos obtenidos en un centro médico de alta complejidad de Buenos Aires, recopilados a partir de estudios de MAPA de 24 horas. Examinamos las características clínicas de los pacientes, los resultados de laboratorio, los estudios de imagen y sus resultados durante el período de seguimiento. Nuestro estudio incluyó personas de 18 años o más a las que se les había diagnosticado hipertensión. Definimos HTAN como aquellos casos con valores de presión arterial ≥ 120/70 mmHg durante el periodo nocturno. Resultados: Fueron incluidos 981 pacientes en el análisis final. De ellos, el 53 % eran hombres; la edad media era de 59,4 años. Presentaban HTAN 63,6 % (n=624). Clasificamos la HTAN en cuatro estratos de gravedad para comparar, según el valor de presión arterial sistólica nocturna: 83-119 mmHg, 120-139 mmHg, 140-159 mmHg y 160-220 mmHg. Se registraron eventos adversos cardiovasculares mayores en 8 (2,2 %), 17 (4,1 %), 8 (5,6 %) y 7 (11,3 %) sujetos, respectivamente, y esta diferencia entre grupos fue estadísticamente significativa (p=0,007). El análisis multivariado de regresión de Cox demostró que la presencia de HTAN fue un predictor independiente de eventos cardiovasculares adversos (HR 3,60; IC 95% 1,12-11,5; p=0,033), incluso al considerar la presencia de hipertensión arterial diurna. Conclusión: En esta cohorte contemporánea, la HTAN y su gravedad se asociaron independientemente con la incidencia de eventos cardiovasculares adversos.

ABSTRACT Background: In the diagnosis and follow-up of arterial hypertension (HTN) most practice guidelines recommend ambulatory blood pressure monitoring (ABPM). In this regard, there is increasing evidence supporting the superiority of nocturnal hy pertension (NHTN) as a predictor of cardiovascular events. Little is known about the relationship with cardiovascular events according to the severity of NHTN. Furthermore, it is unclear from what nighttime pressure value the risk begins to increase. Objectives: The aim of this study was to determine whether the presence of NHTN and its severity levels are associated with adverse cardiovascular outcomes during follow-up. Methods: An observational study was performed analyzing data collected from 24-hour ABPM studies obtained in a high complexity medical center in Buenos Aires. We examined patients' clinical characteristics, laboratory findings, imaging studies and their results during the follow-up period. Our study included ≥18 year-old persons who had been diagnosed with hypertension. We defined NHTN as those cases with blood pressure values ≥120/70 mmHg during the nighttime period. Results: The final analysis included 981 patients. Among these, 53% were men, mean age was 59.4 years and NHTN was present in 63.6% of cases (n=624). Nocturnal HTN was classified into four severity strata for comparison, according to the nighttime systolic blood pressure value: 83-119 mmHg, 120-139 mmHg, 140-159 mmHg and 160-220 mmHg. Major adverse cardiovascular events were recorded in 8 (2.2%), 17 (4.1 %), 8 (5.6%) and 7 (11.3%) subjects, respectively, and this differ ence between groups was statistically significant (p=0.007). Multivariate Cox regression analysis showed that the presence of NHTN was an independent predictor of adverse cardiovascular events (HR 3.60; 95% CI 1.12-11.5; p=0.033), even when considering the presence of daytime hypertension. Conclusion: In this contemporary cohort, NHTN and its severity were independently associated with the incidence of adverse cardiovascular events.

Identificación de infección por el virus de la inmunodeficiencia humana en dos receptores de órgano sólido tres años después del trasplante / Identification of HIV infection in two solid organ recipients three years after transplantation

El examen de rutina de los donantes de órganos para detectar la infección por el virus de la inmunodeficiencia humana (HIV) ha hecho que la transmisión del virus mediante el trasplante de órganos sea poco común. Sin embargo, a pesar de las pruebas de detección de rutina, la transmisión del HIV continúa siendo un riesgo del trasplante de órganos ya que, a diferencia de los tejidos, los órganos sólidos no se pueden procesar, desinfectar, ni modificar para inactivar patógenos infecciosos. A continuación, se describe un caso de posible transmisión de HIV por trasplante de órganos de un donante previamente seronegativo a dos de sus receptores.

Routine screening of organ donors to detect human immunodeficiency virus (HIV) infection has detected the rare transmission of the virus through organ transplantation. However, despite routine screening, HIV transmission remains a risk in organ transplantation since, unlike tissues, solid organs cannot be processed, disinfected, or modified to inactivate infectious pathogens. A case of possible transmission of HIV by organ transplant is described below, from a previously seronegative donor to two recipients.

Association between chronic kidney disease stages and changes in ambulatory blood pressure monitoring parameters / Associação entre estágios da doença renal crônica e alterações dos parâmetros da monitorização ambulatorial da pressão arterial

Abstract Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM). Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM. Methodology: This is a cross-sectional study with 851 patients treated in outpatient clinics of a university hospital who underwent ABPM examination from January 2004 to February 2012 in order to assess the presence and control of AH. The outcomes considered were the ABPM parameters. The variable of interest was CKD staging. Confounding factors included age, sex, body mass index, smoking, cause of CKD, and use of antihypertensive drugs. Results: Systolic BP (SBP) was associated with CKD stages 3b and 5, irrespective of confounding variables. Pulse pressure was only associated with stage 5. The SBP coefficient of variation was progressively associated with stages 3a, 4 and 5, while the diastolic blood pressure (DBP) coefficient of variation showed no association. SBP reduction was associated with stages 2, 4 and 5, and the decline in DBP with stages 4 and 5. Other ABPM parameters showed no association with CKD stages after adjustments. Conclusion: Advanced stages of CKD were associated with lower nocturnal dipping and greater variability in blood pressure.

Resumo Introdução: A avaliação da pressão arterial (PA) tem impacto no manejo da hipertensão arterial (HA) na doença renal crônica (DRC). O portador de DRC apresenta padrão específico de comportamento da PA ao longo da monitorização ambulatorial da pressão arterial (MAPA). Objetivos: O objetivo do corrente estudo é avaliar as associações entre os estágios progressivos da DRC e alterações da MAPA. Metodologia: Trata-se de um estudo transversal com 851 pacientes atendidos nos ambulatórios de um hospital universitário que foram submetidos ao exame de MAPA no período de janeiro de 2004 a fevereiro de 2012 para avaliar a presença e o controle da HA. Os desfechos considerados foram os parâmetros de MAPA. A variável de interesse foi o estadiamento da DRC. Foram considerados como fatores de confusão idade, sexo, índice de massa corporal, tabagismo, causa da DRC e uso de anti-hipertensivos. Resultados: A PA sistólica (PAS) se associou aos estágios 3b e 5 da DRC, independentemente das variáveis de confusão. Pressão de pulso se associou apenas ao estágio 5. O coeficiente de variação da PAS se associou progressivamente aos estágios 3a, 4 e 5, enquanto o coeficiente de variação da pressão arterial diastólica (PAD) não demonstrou associação. O descenso da PAS obteve associação com estágios 2, 4 e 5, e o descenso da PAD, com os 4 e 5. Demais parâmetros da MAPA não obtiveram associação com os estágios da DRC após os ajustes. Conclusão: Estágios mais avançados da DRC associaram-se a menor descenso noturno e a maior variabilidade da pressão arterial.

Background: Blood transfusion holds utmost importance in comprehensive obstetric care and Gynaecology. The present study has been done to evaluate the indications of blood transfusion in the Obstetrics and Gynaecology Department. Methods: The retrospective observational study was conducted between April 2023 to April 2024 in Department of Obstetrics and Gynaecology, Government Medical College, Saharanpur. Results: A total of 257 units of Blood was transfused between April 2023 to April 2024 in Obstetrics and Gynaecology Department. 60.6% transfusion were in age group 21-30 years. 48.26% transfusion were in hemoglobin 7-9 gm/dl. Most common blood group transfused was B positive 40.79% and 85.2% transfusion were packed red blood cell, 84.07% had single unit blood transfusion, 57.25% had transfusion for anemia in pregnancy, 36.84% transfusion were for abnormal uterine bleeding. Conclusions: Prevalence of anemia in reproductive age group is an important reason for blood transfusion in obstetrics and gynaecology. Hence emphasis should be to treat anemia through drugs to reduce unnecessary transfusion especially single unit transfusion.

A cross-sectional descriptive study of clinical autonomic dysfunction in diabetic peripheral neuropathy

Background: Adults having type 2 diabetes mellitus satisfying inclusion and exclusion criteria will be included. Consent of those who fit into inclusion criteria taken. 100 patients were analysed on the basis of history, clinical presentations, investigations. Patients presenting with signs and symptoms of neuropathy were accessed by nerve conduction studies (NCV), autonomic testing, heart rate variation with deep breathing, blood pressure response to standing. Arterial blood gas analysis, and CT /MRI also done. Methods: 100 patients of type 2 diabetes were taken and study of autonomic dysfunction was done for 3 months across tertiary health care centre. Results: Out of 100 diabetic patients under study 54 patients (54%) had diabetic neuropathy. Out of these 54, distal sensory motor neuropathy- most common (77%), sensory neuropathy- 24%. Axonal neuropathy was more prevalent than demyelinating neuropathy. Out of 100, 51 (51%) patients have autonomic neuropathy. Peripheral neuropathy was most common complication in which distal sensory motor polyneuropathy were common. Most common symptom of autonomic neuropathy was postural dizziness followed by erectile dysfunction. Conclusions: Most common complication of type 2 DM is neuropathy. Most common neuropathy was distal sensory motor polyneuropathy whereas most common symptom of diabetic neuropathy was postural dizziness. Other autonomic dysfunction was change in blood pressure and heart after standing.

Immediate effects of Chandra Nadi Shuddhi Pranayama on blood pressure, heart rate and rate pressure product among normal individuals: an experimental study

Background: Chandra Nadi Shuddhi Pranayama is a type of alternate nostril breathing which is the control-positive inhalation and exhalation process. Alternate nostril breathing technique shows the best result in health improvement especially in controlling the blood pressure. It activates the parasympathetic nervous system which dilates blood vessels, decreases the heart rate which leads to reduce blood pressure. Many studies have been done to see effects of breathing exercises on cardiovascular system however, no such studies were done to see specific and immediate effect of Chandra Nadi Shuddhi on cardiovascular system. In this article, we will look how Chandra Nadi Shuddhi improves blood pressure, heart rate, and rate pressure product. Methods: Ethical clearance and participant consent was taken. Study design was experimental study. The 80 subjects were taken by convenient sampling. Participants were asked to perform 27 rounds of the Chandra Nadi Shuddhi Pranayama and outcome measures were assessed before and immediately after performing Chandra Nadi Shuddhi. The normality of the data was assessed using parametric paired t test. Results: Immediate effect of Chandra Nadi Shuddhi Pranayama showed that there was statistically significant decrease in blood pressure, heart rate and rate pressure product (p=0.0001, 0.0045, 0.0001 respectively) Conclusions: There is immediate effects of Chandra Nadi Shuddhi Pranayama on individuals with normal blood pressure.These results suggest a possible role for this technique in helping to control hypertension, lower anxiety and depression, improve breathing and immunity.

Navigating antenatal complexity: a case report of Bombay blood group and anaemia challenges

The Bombay blood group is a rare blood type, predominantly found in regions with a high prevalence of consanguineous marriages due to its autosomal recessive inheritance pattern. This blood group is unique because individuals lack the H antigen, a precursor to the A and B antigens found in other blood types, making their blood type exceptionally rare. Managing antenatal patients with the Bombay blood group presents significant challenges, especially in cases of anaemia or any instance of blood loss. The primary difficulty arises from the scarcity of compatible blood for transfusion, as individuals with the Bombay blood group can only receive blood from other Bombay group donors. This rarity complicates the management of potential complications during pregnancy, labour, and delivery. To address these challenges, minimizing blood loss is essential during all stages of pregnancy, particularly during labour, Caesarean sections, and in the prevention of postpartum haemorrhage. Effective management requires a multidisciplinary approach, involving obstetricians, haematologists, and blood bank services. One potential strategy to mitigate the risk of blood shortages is autologous blood transfusion. This option can be particularly valuable during pregnancy; however, it requires careful consideration of the potential risks and benefits. The procedure should be conducted under the guidance of healthcare professionals experienced in managing such cases, ensuring the safety and well-being of both the mother and the foetus. In our case report, we present an antenatal patient with anaemia and the challenges encountered during the antenatal and postnatal periods. This case highlights the complexities of managing pregnancies involving the Bombay blood group. It underscores the importance of a well-coordinated, multidisciplinary approach to optimize outcomes for both mother and child.

Evolución de los parámetros hematológicos y óbito en internados con COVID-19 en un hospital de Paraguay, 2021

Introducción: Los parámetros hematológicos proporcionan al equipo médico marcadores pronósticos útiles en la evolución clínica de la enfermedad de COVID-19. El objetivo fue analizar la relación entre la evolución desfavorable de los valores hematológicos y el óbito de los pacientes internados con COVID-19. Metodologia: El estudio es observacional, correlacional y longitudinal. Se realizó la revisión de fichas clínicas de los pacientes mayores a 18 años internados entre enero y marzo del 2021. Se registró en una planilla Excel el resultado de los parámetros hematológicos al ingreso, a las 48 horas, a los 8 días y al egreso. Los datos fueron analizados con Epi Info 7.1 (CDC, Atlanta) según estadística descriptiva. Resultados: De 144 pacientes, se observaron 68 (47,2%) muertes, con predominio del sexo masculino (63,2%) y, mayores a 60 años (47,1%). Los factores asociados a mortalidad fueron la hipertensión (52,9% vs 31,6%; p=0,009), la diabetes (50% vs 26,3%; p=0,003) y, la obesidad (41,2% vs 25%; p=0,039). Los parámetros hematológicos desfavorables asociados a la mortalidad se presentaron a partir de los 8 días de internación con leucocitosis (64,1% vs 33,3%; p=0,003), linfopenia (96,8% vs 79%; p=0,008), neutrofilia (98,5% vs 87,7%; p=0,029) y, un elevado índice neutrófilo/linfocito (INL) (96,9% vs 75,4%; p=0,001). Discusión: Los parámetros hematológicos que se asociaron con la mortalidad fueron leucocitosis con neutrofilia, linfopenia e INL elevado. Estos parámetros podrían tener valor pronóstico en el seguimiento para contribuir en el manejo de estos pacientes.

Introduction: Hematological parameters provide the medical team with useful prognostic markers in the clinical evolution of COVID-19 disease. The objective was to analyze the relationship between the unfavorable evolution of hematological values and the death of patients hospitalized with COVID-19. Methodology: The study is observational, correlational, and longitudinal. A review of the clinical records of patients over 18 years of age hospitalized between January and March 2021 was carried out. The results of the hematological parameters at admission, at 48 hours, at 8 days and at discharge were recorded in an Excel spreadsheet. The data were analyzed with Epi Info 7.1 (CDC, Atlanta) according to descriptive statistics. Results: Of 144 patients, 68 (47.2%) deaths were observed, with a predominance of males (63.2%) and those over 60 years of age (47.1%). The factors associated with mortality were hypertension (52.9% vs 31.6%; p=0.009), diabetes (50% vs 26.3%; p=0.003) and obesity (41.2% vs 25 %; p=0.039). The unfavorable hematological parameters associated with mortality occurred after 8 days of hospitalization with leukocytosis (64.1% vs 33.3%; p=0.003), lymphopenia (96.8% vs 79%; p=0.008), neutrophilia (98.5% vs 87.7%; p=0.029) and a high neutrophil/lymphocyte ratio (NLR) (96.9% vs 75.4%; p=0.001). Discussion: The hematological parameters that were associated with mortality were leukocytosis with neutrophilia, lymphopenia, and elevated NLR. These parameters could have prognostic value in follow-up to contribute to the management of these patients.

Diagnóstico molecular de bacteriemias: beneficios del empleo del panel de sepsis BCID2 de Filmarray en un hospital de tercer nivel / Molecular diagnosis of bacteriaemia: benefits of using the FilmArray® BCID2 sepsis panel in a third level hospital

Resumen Introducción : Los retrasos en el tratamiento anti microbiano adecuado de las bacteriemias prolongan la estadía hospitalaria, aumentan la mortalidad e in crementan los costos. Aún hoy en día se requiere un tiempo considerable para obtener la identificación y antibiograma de los microorganismos en los hemocul tivos positivos. El objetivo fue evaluar el impacto de la implementa ción del panel BCID2 de FilmArray® (FA) sobre el tiempo de inicio de tratamientos antimicrobianos adecuados y sobre los costos potenciales de los mismos. Métodos : Estudio observacional retrospectivo de los hemocultivos positivos de pacientes hospitalizados, procesados por FA y por metodología tradicional. Se evaluaron los cambios de antimicrobianos en base a los resultados del FA. Se calcularon los días de reducción de tratamiento antimicrobiano y el ahorro potencial en el uso de los mismos, teniendo en cuenta también los costos del FA. Resultados : Se analizaron 87 episodios de bacte riemia. En 42 (48.3%) de ellos se desescaló el trata miento a antimicrobianos de menor espectro, en 7 (8%) se escaló a antimicrobianos de mayor espectro, en 8 (9.2%) se cambió el antimicrobiano sin variar el espectro y en 30 (34.5%) no se realizaron cambios con los resultados del FA. Los cambios de antimicrobianos se realizaron en promedio 2.3 días más rápido que con los métodos convencionales. Se calculó un ahorro potencial de US$ 7408. Conclusión : La implementación del panel BCID2 de FilmArray ® permitió adecuar los tratamientos antimi crobianos más rápidamente acortando la duración de los tratamientos empíricos de amplio espectro, lo cual resultó costo-efectivo.

Abstract Introduction : Delay in initiating appropriate anti microbial therapy prolongs hospitalization, increases in-hospital mortality, and raises economic costs. Cur rently, the identification and susceptibility testing of bacteria in positive blood cultures require a considerable amount of time. The objective of this study was to assess the impact of the BCID2 FilmArray® (FA) panel on the timing of appropriate antimicrobial therapy and potential anti microbial costs. Methods : This is a retrospective observational study focused on positive blood cultures in hospitalized pa tients. FA processing was conducted concurrently with routine sample processing. Changes in antibiotic treat ments based on FA results were evaluated, and the re duction in antimicrobial therapy duration and associated cost savings were calculated. Results : Eighty-seven bacteremia episodes were ana lysed. In 42 (48%) of them antimicrobial therapy was de-escalated to narrower spectrum agents, while in 7 (8%) therapy was escalated to broader spectrum anti microbials. Additionally, in 8 (9%) antimicrobials were switched without changing spectrum and in 30 (34%) no changes were made based on FA results. Antimicrobial changes were made 2.3 days faster than with routine sample processing resulting in calculated potential sav ings of US$ 7408. Conclusion : The implementation of FA facilitated a faster administration of appropriate antimicrobial therapy, leading to a reduction in the duration of broad-spectrum empirical antimicrobial therapy and subse quent economic savings.

Background: Cord blood lipid profile in neonates helps to screen for neonatal dyslipidaemia which is associated with long term morbidity mainly cardiovascular disease.Methods: The present study is a observational study done in government medical college, Chidambaram for a period of 2 years from October-2020 till September-2022 with 222 term and pre-term small or appropriate for gestational age (AGA) neonates using cord blood lipid profile.Results: In the present study of above mentioned 222 neonates, preterm accounts for 30.1% and term neonates accounts for 69.9%. AGA was 63.1% and SGA was 36.9%. Term AGA was 38.2%, term SGA 31.5%, preterm AGA was 24%, preterm SGA was 5.4%. Conclusions: Preterm AGA had higher cord lipid profile values compared to the term AGA neonates. Preterm SGA neonates had lower cord lipid profile of HDL, and LDL as compared to preterm AGA neonates. SGA neonates had higher total cholesterol, triglycerides and VLDL compared to AGA neonates. SGA neonates had lower LDL and HDL as compared to AGA neonates.

Application of warm water foot bath therapy for stage two hypertension clients in the family context

Hypertension is often regarded as a silent killer because the disease often causes no symptoms in the sufferers. This disease does not only need treatment, but family support is required to prevent and treat family members who are suffering. The objective of the study is to analyze the application of warm water for foot bath therapy to lower blood pressure in people suffering from hypertension. The design used is descriptive with case studies, through family nursing process. Monitoring of warm water foot bath was carried out for 3 days, before and after measuring the blood pressure Results: there was a decrease in blood pressure after 3 days of action. In family 1, the initial blood pressure was 160/90 mmHg, after 3 days of action it decreased to 145/85 mmHg. Family 2 before therapy 150/100 mmHg, decreased to 140/86 mmHg after soaking feet in warm water. The decrease in blood pressure observed in both families was more than 10 mmHg. The application of foot bath therapy using warm water which is carried out for 3 days, is effective in reducing blood pressure in hypertension cases. Suggestions are recommended for families and subjects to be able to apply independently warm water foot bath therapy and carry out routine blood pressure checks at the nearest healthcare facility.

A comparative study of ProRithm and standard monitoring techniques for non-invasive blood pressure measurement using photoplethysmography and electrocardiography signals through artificial intelligence/machine learning methods

Background: Multi-parameter monitoring devices are essential for providing real-time patient data, which is crucial for effective healthcare interventions. This clinical trial evaluated the accuracy of the ProRithm beat-to-beat cuffless device for arterial blood pressure monitoring, comparing it with a standard sphygmomanometer. Methods: This observational study included 30 subjects aged 18 and above. Systolic and diastolic blood pressure measurements from both the ProRithm device and the Philips Monitor were compared using statistical analysis. Results: The analysis revealed no statistically significant differences between the ProRithm device and the manual method. In comparison with manual measurements using a sphygmomanometer, the mean systolic blood pressure was 131.2 mmHg with ProRithm it was 129.3 mmHg. Similarly, with the manual method, while the mean diastolic blood pressure was 76.2 mmHg and with ProRithm it was 75.9 mmHg. Conclusions: This study indicates that portable, small-sized devices like ProRithm, which facilitate remote monitoring, are effective for real-time blood pressure assessment in clinical settings.

Efficacy of intervention towards blood donation to increase voluntary blood donation: a systematic review

Although blood is the essence of life, and is one of the most precious donations; blood transfusion services are facing shortage of blood all over the world. A significant percentage of people have false beliefs about blood donation. Increase in the level of knowledge and correction of false beliefs should be the top most priority. Therefore, studying factors contributing to their knowledge, attitude and practice of blood donation is essential. There are studies that investigated the effectiveness of interventions or procedure changes in blood donation settings on outcomes including donor deferral, disclosure of risk factors, and rates of errors and omissions. Researchers also identified several interventions to improve donor compliance that have been tested in blood donation settings and provided evidence for the effectiveness of computerized interviews in improving detection of risk factors. Interventions can utilize the processes of change (POC) measure to guide stage matched interventions to encourage use of relevant experiential and behavioral strategies to increase blood donation. Interventions to recruit and retain blood donors in the general population have been classified into five approaches: motivational, reminders/asking, measurement of cognitions, incentives, and preventing vasovagal reactions. Effective recruitment and retention are two different processes and may require different approaches. For example, retention may be influenced more by interventions that focus on actions during or after donation rather than interventions prior to the blood donation appointment.

Comparison of blood loss in total knee replacement surgery with and without tranexamic acid: a prospective, time framed and observational analytical study

Background: Total knee replacement is one of the common orthopaedic procedures performed worldwide. Blood transfusion is one of the major requirements in TKR procedure due to the amount of blood loss during and after the procedure. We carried out a prospective study to determine the efficacy of tranexamic acid in controlling blood loss during TKR procedure. Methods: Study was conducted at a tertiary care centre, involving cases operated by a single surgeon. Study included 140 patients undergoing primary TKR for advance degenerative disease of knee and were divided into two groups of 70 each, one group that received tranexamic acid before surgery and another group that did not receive tranexamic acid before surgery. Patient with allergy to the drug, hepato/renal dysfunction, DVT, abnormal PT and INR were not included. Tranexamic acid was given intravenously as well as intra-articular. Results: Pre-operative haemoglobin ranged from 10.2 gm% to 14.4 gm% in the group getting tranexamic acid and from 10% to 14 % in the group not getting tranexamic acid. Post operatively haemoglobin varied from 8.4 gm% to 12.8 gm% in Group 1 and from 7.8 gm% to 12 gm% in Group 2. Difference of mean post-operative Hb (p=0.0045) and PCV (p=0.0024) in two groups was statistically significant. Conclusions: We concluded that administration of tranexamic acid reduces the blood loss as well as need of blood transfusion in a patient undergoing total knee replacement.
