RESUMO

Abstract The antioxidant activity of Tetragonisca angustula honey (TAH) and its ethanolic extract (TAEE) were investigated. The total levels of phenolic (TPC) and flavonoids (TFC) were also evaluated. The results for TPC were 19.91 ± 0.38 and 29.37 ± 1.82 mg GAE g-1 and for TFC 0.20 ± 0.02 and 0.14 ± 0.01 mg QE g-1 of TAH and TAEE, respectively. Antioxidant activities were 73.29 ± 0.49% and 93.36 ± 0.27% in the DPPH assay and 71.73 ± 4.07% and 97.86 ± 0.35% in ABTS+ for TAH and TAEE, respectively. The total reducing activity was determined by the method of reducing power (PR) and iron ion (Fe III) and the results varied in PR from 151.7 ± 25.7 and 230.7 ± 25.2 mg GAE L-1, for TAH and TAEE respectively and for (Fe III) in EC50 0.284 in TAEE and 0.687 in TAH. Chemical analysis by HPLC-DAD of the ethanolic extract (TAEE) revealed the presence of ferulic acid as majority phenolic component in the extract. The 1H NMR analysis confirmed this structure and showed the also presence of glucose, citric acid, succinic acid, proline and hydrocarbon derivatives. In addition, the botanical origin was also investigated and showed a multifloral characteristic, having found 19 pollen types with a botanical predominance of the Anacardiaceae family, with Tapirira pollen occurring as predominant (42.6%) and Schinus as secondary (25.7%). The results showed that T. angustula honey is an interesting source of antioxidant phenolic compounds due to its floral origin and can act as a protector of human health when consumed.

RESUMO

ABSTRACT Introduction: Brazil has many inequities in the healthcare provided nationwide. Therefore, in order to access challenges in treatment, available resources and current practices, to identify barriers in delivering a good quality of care among Brazilian centers treating children and adolescents with Non-Hodgkin Lymphoma (NHL) and to generate a future prospective guideline, a customized online survey was distributed to pediatric hematologists and oncologists across the country. Results: A total of 97 surveys were completed (35% response rate), from 47 cities in all Brazilian regions and 79 units of care, with a median of 1 answer by the center (range 1 - 5). Most respondents work at an institution supported exclusively by public/philanthropic resources (58%), with an average of 5 to 9 new cases/year (49%), and 41% have 4 to 6 oncologists/centers. Additionally, 22% have no easy access to the intensive care unit, 26% have no access to Rasburicase, 28% have no access to Rituximabe as front-line therapy and 41% have unreliable methotrexate monitoring levels. Those differences cannot be explained thoroughly by regional wealth variances, nor by the financing model. Regarding the pathology service, 70% consider having reasonable quality assistance, but the timeframe to deliver diagnosis is satisfactory to 46%. There is no uniform management of care, with the current guideline from the Sociedade Brasileira de Oncologia Pediátrica being adopted by 54 to 59%, depending on the NHL subtype. Conclusion: This study provides insights into the heterogeneity of care among Brazilian centers. Recognizing those diversities will support the design of effective strategies and collaboration nationwide.

RESUMO

Los intervalos de referencia (IR) dependen de la población y de las características metrológicas del procedimiento de medida utilizado. A pesar de las recomendaciones internacionales, son pocos los laboratorios que establecen sus propios IR para cada magnitud por la dificultad para conseguir voluntarios de referencia y el elevado costo económico asociado. La International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) acepta la adopción de IR bibliográficos o su cálculo por métodos indirectos dado su bajo costo y fácil obtención. Existen varias fuentes confiables de IR bibliográficos para el hemograma. No obstante, para el recuento plaquetario, es una práctica común de los laboratorios emplear el rango de valores de 150-450.109 /L independiente de la metodología utilizada y grupo etario. El objetivo de este trabajo fue revisar los IR bibliográficos disponibles para el recuento plaquetario y estimarlo empleando el método indirecto de Hoffmann a partir de nuestra población. Los métodos indirectos se basan en aplicar criterios de exclusión y cálculos matemáticos sobre los resultados de una base de datos de laboratorio. Nuestros IR para el recuento plaquetario se comparan con los bibliográficos, que han sido establecidos por técnicas de muestreo directo. Por este motivo y dado que no existen estudios poblacionales que lo avalen, sería apropiado reemplazar el rango de 150-450.109 / L. Estos límites podrían seguir empleándose como puntos de corte o niveles de decisión médica para definir, según la clínica y otros resultados de laboratorio, los pacientes que ameritan un seguimiento posterior (AU)


Reference ranges (RR) depend on the population and the metrological characteristics of the measurement procedure used. Despite international recommendations, few laboratories establish their own RRs for each magnitude because of the difficulty in obtaining reference volunteers and the associated high economic cost. The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) accepts the use of literaturebased RRs or RRs calculated by indirect methods because of their low cost and easy collection. There are several reliable sources of literature-based RRs for the Cell Blood Count. However, for platelet count, it is common laboratory practice to use the range of 150-450,109 /L regardless of the methodology used and age group. The aim of this study was to review the available literature regarding RRs for platelet count and to establish it using the indirect Hoffmann method in our population. Indirect methods are based on applying exclusion criteria and mathematical calculations on the results of a laboratory database. Our RRs for platelet counts are compared with those in the literature, which have been established by direct sampling techniques. Therefore, and given that there are no population studies to support these findings, it would be appropriate to replace the 150-450,109 /L range. These limits may continue to be used as cut-off points or medical decision levels to define, according to clinical manifestations and other laboratory results, patients who warrant further follow-up (AU)

RESUMO

The Chechim nchabe is a traditional food widely consumed in Foumban, Foumbot, Koutaba, Massangam, Kouoptamo, Malentouen and Magba, 07 Departments of Noun (West region of Cameroon). It is obtained by fermenting cassava sticks cooked on the surface of river or spring water. Unfortunately, the bad hygienic quality of the environment during production promotes its contamination by pathogenic germs. The objective of this study is to carry out a second fermentation in order to reduce contamination of Chechim nchabe by pathogens germs during production. To achieve this objective, a survey on the socio-economic data, profile of the producers, production protocol and characteristics of product have been realized. After microbiological analysis of Chechim nchabe, a second fermentation was performed in the laboratory. From the results, it appears that all the producers are women, aged between 51 and 58 years and 87% of them not attending school. The water used for soaking the cassava revealed that 54% of women use river water and 46% spring water. The Chechim nchabe samples collected after traditional production in the 07 Departments of Noun, show average contamination of Enterobacteriaceae, moulds, staphylococci, Escherichia coli and lactic acid bacteria with respective concentrations of 4.7; 4.1; 4.4; 4.7 and 4.8 Log10ufc/mL. However, Chechim nchabe produced in urban areas such as Foumbot and Foumban recorded low contamination compared to that produced in rural areas like Massangam, which were heavily contaminated with Escherichia coli and Enterobacteriaceae. It was also noted that the Chechim nchabe produced in spring water is more contaminated than that produced in river water. The second fermentation for 10 hours of Chechim nchabe in a basin, after 12 hours of traditional fermentation, eliminated all of pathogenic germs from Chechim nchabe. This second fermentation of 10 hours could be a solution to guarantee the sanitary quality of Chechim nchabe before its consumption.

RESUMO

Background: Prescribing drugs are an important skill which needs to be continuously assessed and refined accordingly. Many drugs especially antimicrobials and fixed dose combinations that maybe irrational are being prescribed. Hence, this study was undertaken to analyze the rational prescribing guidelines in post-operative patients which will help doctors to update their knowledge and improve their attitude toward selecting cost effective treatment. Aim and Objectives: The aims of this study were as follows: (i) To evaluate prevailing prescription trends and (ii) to evaluate rationality of prescriptions in post-operative cases of surgery, orthopedics, obstetrics, and gynecology (OBG), and Otorhinolaryngology (ORL) departments. Materials and Methods: A prospective observational study was conducted in post-operative wards of departments of surgery, orthopedics, ORL, and OBG of Dr. B. R. Ambedkar Medical College and Hospital, Bengaluru. The study duration was 15 months from December 2018 to March 2020 with a sample size of 2000. Results: In the present study, female preponderance (54.4%) was seen. Majority of the drugs (77.3%) were prescribed under brand name. The most common group of drugs prescribed was non-steroidal anti-inflammatory drugs (135%) and the antibiotic was Cephalosporins (77.5%). As per the World Health Organization (WHO) core prescribing indicators, 6.25 were the average drugs per prescription. Conclusion: According to the WHO core prescribing indicators, polypharmacy was observed and prescribing by generic name was also less. However, there was no irrational use of antibiotics in post-operative cases in our study which reduces the chances of development of antibiotic resistance. Practice of prescribing drugs from the essential drugs list (EDL) was less. The study suggests incorporating educative initiative, development of drug policy, and an EDL-based hospital formulary to ensure rational use of medicines.

RESUMO

Background: South Africa reported a new variant of SARS-CoV-2, named 'Omicron,' to the World Health Or-ganization on November 24, 2021. Scientometric analysis quantify all currently available written communica-tion, the authors of that communication, and their citation analysis. The study's goal was to use the Scopus and Web of Science databases to look at the research metrics of Omicron publications published between Jan-uary 1965 and March 2020. Methods:All scientific research outputs with the word 'Omicron' in the title were retrieved from the Web of Science (January 1965 to March 2022) and Scopus (January 1896 to March 2022) databases on April 10, 2022. The data was analyzed based on year-wise publications; leading authors; predominant journals in publishing, highly cited articles with citations; type of publications; subject classification, frequently used keywords, geo-graphical distribution of publication, language, and more contributed institutions. Results: There were 1229 research outputs for WoS and 655 from Scopus. The number of publications for WoS increased from 22 in 1965 to 265 in 2022, while Scopus increased from 1 in 1896 to 356 in 2022. Both the databases identified the author Yuen KY as the highest contributor; Journal of Virology and Nature as the predominant journals; the Lancet as highly cited journal; majority as original articles; frequently used key-words as 'SARS-CoV-2'; the United States of America as the most productive country; majority publication in English. The publications were mainly on the subjects Chemistry and Medicine by WoS and Scopus, respec-tively. The most productive institute was the ‘University of California Systems’ by WoS and the ‘University of Hong Kong’ by Scopus. Conclusion: The term 'Omicron' first appeared in the domain of Chemistry in the late 18th century. The growth pattern of publication was not consistent. The above research metrics will be helpful to researchers in the coming days.

RESUMO

Introduction: Rhythm disorders (RDs) or arrhythmias are poor prognostic factors during heart failure (HF). Our objective was to study the frequency of rhythm disorders presented by patients treated for HF in Parakou, Benin in 2017. Methods: This was a cross-sectional, descriptive and analytical study. It consisted of a systematic recruitment of all patients admitted for heart failure in the cardiology units of the city of Parakou from March to August 2017. The diagnosis of RDs was made by cardiac auscultation completed by electrocardiographic recording (standard and Holter over 24 hours). The Lown classification was used to describe the severity of ventricular TRs. The threshold for significance was p < 5%. Results: A total of 83 heart failure patients aged 61.47 ± 15.97 years with a sex ratio of 1.08 were selected. Arrhythmia was detected by auscultation in 20.48%; by standard electrocardiogram (ECG) in 25.83% and by Holter ECG in 97.59% of patients. Among the arrhythmias detected by Holter ECG, 81.48% were atrial, including 28.79% of atrial fibrillation. RDs was ventricular in 90.12% of which 47.95% were severe. Left ventricular systolic dysfunction was significantly associated with ventricular arrhythmias. On the other hand, the frequency of ventricular arrhythmias was not associated with the severity of the HF according to the NYHA classification. Conclusion: In Parakou, RDs are frequent in patients with HF. Holter ECG should be included in the follow-up of heart failure patients in order to improve their management.

RESUMO

Vamana is the Agrya karma for Kaphaja vikaras. Madanaphala - Randia dumetorum Lam is the drug of choice for Vamana karma because of its property – Anapayitwat (without untoward effect). Specific collection method, season and processing is required to get Phalapippali to possess above quality. Madana shalatu– Unripen fruits of Madanaphala is an Abhavapratinidhi dravya mentioned in Sushrutha Samhita and Ashtanga Hrudaya which does not require this processing- Samskara. So, in the present study comparative qualitative and quantitative physicochemical and phytochemical analysis of the Madana Shalatu, Pakwa Madanaphala Ripen fruit of Madanaphala and Madanaphala Pippali– Processed fruits of Madanaphala has been carried out. Aim: 1. Pharmacognostic, Physicochemical and Phytochemical analysis of Madana Shalatu, Pakwa Madanaphala, Madanaphala Pippali. 2. Comparative qualitative and quantitative phytochemical analysis of Madana Shalatu, Pakwa Madanaphala, Madanaphala Pippali. Method: 1. Pharmacognostic study – Macroscopic study and Microscopic study. 2. Preliminary physico chemical analysis. 3. Qualitative phyto chemical evaluation of aqueous and alcoholic extracts of the test drugs. 4. Quantitative analysis– UV Spectrophotometry. Result: Microscopic study, qualitative phyto chemical evaluation of all test drugs did not showed much differences. In total saponin estimation by UV Spectrophotometry of methanol and Water extract of ripen processed fruits of Randia, Ripen fruits of Randia and Unripen fruits of Randia is found to contain 73.71, 83.23, 71.35 and 72.62, 92.44, 75.25µg DE/mL of Saponin content respectively. Conclusion: Quantity of Saponin which is the main active principle in Randia Dumetorum responsible for Vamana Karma was similar in the Madana Shalatu and in Phala Pippali, whereas it was highest in Pakwa Madanaphala, thus it may be used like Phala Pippali without any laborious process of Samskara. Further Toxicity studies and clinical trials are required to prove its safety and efficacy in humans.

RESUMO

Purpose@#Indians have a higher incidence of cardiovascular diseases, often at a younger age, than other ethnic groups. This higher baseline risk requires consideration when assessing additional cardiac morbidity of breast cancer treatment. Superior cardiac sparing is a critical dosimetric advantage of proton therapy in breast cancer radiotherapy. We report here the heart and cardiac-substructure doses and early toxicities in breast cancer patients treated post-operatively with proton therapy in India’s first proton therapy center. @*Materials and Methods@#We treated twenty breast cancer patients with intensity-modulated proton therapy (IMPT) from October 2019 to September 2022, eleven after breast conservation, nine following mastectomy, and appropriate systemic therapy, when indicated. The most prescribed dose was 40 GyE to the whole breast/chest wall and 48 GyE by simultaneous integrated boost to the tumor bed and 37.5 GyE to appropriate nodal volumes, delivered in 15 fractions. @*Results@#Adequate coverage was achieved for clinical target volume (breast/chest wall), i.e., CTV40, and regional nodes, with 99% of the targets receiving 95% of the prescribed dose (V95% > 99%). The mean heart dose was 0.78 GyE and 0.87 GyE for all and left breast cancer patients, respectively. The mean left anterior descending artery (LAD) dose, LAD D0.02cc, and left ventricle dose were 2.76, 6.46, and 0.2 GyE, respectively. Mean ipsilateral lung dose, V20Gy, V5Gy, and contralateral breast dose (Dmean) were 6.87 GyE, 14.6%, 36.4%, and 0.38 GyE, respectively. @*Conclusion@#The dose to heart and cardiac substructures is lower with IMPT than published photon therapy data. Despite the limited access to proton therapy at present, given the higher cardiovascular risk and coronary artery disease prevalence in India, the cardiac sparing achieved using this technique merits consideration for wider adoption in breast cancer treatment.

RESUMO

The COVID-19 pandemic has challenged the entire world, and patients with diabetes mellitus (DM) have been particularly affected. We aimed to evaluate predictors of mortality during the first 30 days of hospitalization in critically ill patients with COVID-19 and comorbid DM. This prospective study included 110 critically ill patients admitted with COVID-19 infection. Thirty-two (29%) patients had a previous diagnosis of DM. Clinical variables, laboratory tests, and vascular biomarkers, such as VCAM-1, syndecan-1, ICAM-1, angiopoietin-1, and angiopoeitin-2, were evaluated after intensive care unit (ICU) admission. A comparison was made between patients with and without DM. No difference in mortality was observed between the groups (48.7 vs 46.9%, P=0.861). In the multivariate Cox regression analysis, VCAM-1 levels at ICU admission (HR: 1 [1-1.001], P<0.006) were associated with death in patients with DM. Among patients with DM, advanced age (HR 1.063 [1.031-1.096], P<0.001), increased Ang-2/Ang-1 ratio (HR: 4.515 [1.803-11.308] P=0.001), and need for dialysis (HR: 3.489 [1.409-8.642], P=0.007) were independent predictors of death. Higher levels of VCAM-1 in patients with DM was better at predicting death of patients with severe COVID-19 and comorbid DM, and their cut-off values were useful for stratifying patients with a worse prognosis. Vascular biomarkers VCAM-1 and Ang-2/Ang-1 ratio were predictors of death in patients with severe COVID-19 and comorbid DM and those without DM. Additionally, kidney injury was associated with an increased risk of death.

RESUMO

L'objectif de l'étude est d'évaluer la pratique anesthésique au cours des adénomectomies hypophysaires par voie endo nasale à Abidjan. Méthode : Il s'agissait d'une étude rétrospective à visée analytique et descriptive, menée entre le 01 janvier 2010 et le 31 décembre 2020 et portant sur les patients admis au bloc opératoire pour une adénomectomie hypophysaire. Les caractéristiques sociodémographiques, cliniques, anesthésiques, évolutives et pronostiques ont été étudiées. Résultats : Nous avons recensé 102 patients. L'âge moyen était de 44,72±12,14 ans. Le sex ratio était de 1. Le délai de diagnostic était d'un an pour 46% (n = 47) des patients. L'hypertension artérielle était l'antécédent le plus retrouvé. Les principaux motifs de consultation étaient les céphalées et les troubles de l'acuité visuelle. Le syndrome d'hypertension intracrânien a été observé chez 67,6% (n= 69) des patients. Tous les patients ont bénéficié d'une consultation pré anesthésique. Cinquante-huit pourcent (n=59) des patients ont été classés ASA I selon la société américaine d'anesthésie. L'anesthésie générale était le seul schéma anesthésique. La durée de l'anesthésie était de plus de trois heures chez 57% (n=58) des patients et le réveil sur table a concerné 88,2% (n=90) des patients. La mortalité était de 3,9%. La durée de l'anesthésie supérieure à 6 heures (p= 0,0012 ; OR= 55,8 [4,88-637,33]) et la perte sanguine supérieure à 1000 ml (p = 0,0228 ; OR=18,6 2,152- 160,747]) ont constitué des facteurs de mauvais pronostic (p<0,05). Conclusion: La réduction de la létalité au cours de l'anesthésie pour adénomes hypophysaires passe par la lutte contre les facteurs de mauvais pronostics

RESUMO

La pratique de la rachianesthésie est motivée par la qualité de l'analgésie post-opératoire qu'elle procure. Cependant, la rachianesthésie reste comme tout acte médical associée à certains accidents. Méthodes : C'est une étude prospective, descriptive et analytique qui s'est déroulée sur une période d'un (01) mois allant du 07 Mai 2022 au 07 Juin 2022 au CHU d'Angré. Résultats : la rachianesthésie a été réalisée dans 188 des cas, soit un taux de 60% de l'ensemble des interventions. Le sexe ratio était de 0,13 et l'âge moyen était de 33 ± 10 ans. L'antécédent le plus retrouvé était l'HTA. La bupivacaine était le seul anesthésique local utilisé avec comme adjuvant la morphine, le fentanyl ou l'association morphine -fentanyl. Les incidents peropératoires étaient dominés par les troubles hémodynamiques à type d'hypotension artérielle (98,7%) et de bradycardie. Les patients ayant présenté un syndrome de mal être post opératoire représentaient 70,8% de notre effectif. Le Syndrome de Mal Etre post opératoires était dominé par les nausées et vomissements suivis des prurits. Tous les patients ayant présenté un syndrome de mal être post rachianesthésie n'avaient pas bénéficié de prise en charge. La survenue du syndrome de mal être post rachianesthésie était statistiquement associé à la présence de la morphine comme adjuvant (p=0,016). Conclusion : La rachianesthésie est une remarquable technique d'anesthésie. Néanmoins la fréquence des évènements per et post opératoires survenant au décours de cette technique n'est pas négligeable, car ils sont la source d'inconforts notables

RESUMO

Diarrhoeadisease is the second leading cause of death in children under 5 years old, and is responsible for killing about 300, 000 children annually in Nigeria. Oral rehydration therapy (ORT) is the preferred treatment for fluid and electrolyte losses due to diarrhoea in children with mild to moderate dehydration. This study aimed to assess the knowledge and use of ORT in the management of diarrhoea in children under 5 years at Seventh Day Adventist Hospital (SDAH, Ife).Method: A structured questionnaire was adopted for this study design and data was collected using a self-structured questionnaire both self-administered and interviewer administered.Results: Of 80 participants, 44 (55%) of the respondents had heard of ORT before this study, while 36 (45%) had not. 48 (60%) responded that they use oral rehydration solution while 32 (40%) of mothers said they had not used ORT. There was significant difference in both outcomes. The result revealed that there was significant difference in morbidity and mortality between mothers who use ORT and those who do not. But there was no significant difference between the knowledge of ORT compared with its use.Conclusion:Appropriate knowledge of the therapy will positively influence its use which will drastically prevent morbidity associated with diarrhoea as well as contain the incidence of mortality

RESUMO

Nigeria has one of the highest rates of cervical cancer morbidity and mortality in Sub-Saharan Africa. Both the human papillomavirus vaccine (HPV) and cervical screening are effective prevention strategies against both HPV infection and cervical cancer. Lack of awareness, limited knowledge, limited decision-making agency, lack of spousal support and stigma are barriers to uptake of these preventive measures. Cervical cancer is a deadly disease claiming the lives of many women in developing countries due to late presentation which might be influenced by a lack of knowledge of the disease and its prevention. Method: This descriptive study examined the knowledge assessment of cervical cancer among women of reproductive age (15-49), about cervical cancer, its prevention, and their utilization of Pap smear screening; using a convenience sample of 426 women in Ibadan North Local Government Area of Oyo State, Nigeria. Women voluntarily completed a structured questionnaire. Result: Results showed that women who participated in the study were aware of cervical cancer (77%; n=328) but many (62.9%; n= 268) were unaware of Pap smears as the screening tests for cervical cancer. Although 41.3% (n=176) were knowledgeable about cervical cancer, risk factors and prevention, only 9.4% (n=40) had Pap smear tests done. Conclusion: Health care professionals, need to intensify efforts to increase awareness about cervical cancer screening, and encourage women through the different clinics to use these services. The benefits of screening and early diagnosis of cervical cancer should be emphasized to enhance the utilization of cervical cancer screening services.

RESUMO

Objectifs : Identifier les facteurs de mauvais pronostic des pneumopathies acquises sous ventilation mécanique(PAVM) afin d'améliorer leur prise en charge.Patients et methode : Etude prospective, descriptive et analytique portant sur les patients admis en réanimation du CHU d'Angré du 1er novembre 2019 au 31 juillet 2021 et ayant présenté une PAVM.Resultats : Nous avons colligé 43 patients sur 625 admissions soit 6,88%. L'âge moyen était de 49,06 ans. Le sex ratio était de 0,38. Le principal motif d'admission était le coma avec 88,37%. L'HTA et le diabète étaient les principaux antécédents .Les PAVM précoces représentaient 53,49%. Le Klebsiella pneumoniae était le principal germe. Les patients intubés à l'admission représentaient 79,07%. La durée moyenne de ventilation était de 26,95 jours et la durée moyenne d'hospitalisation était de 30,8140 jours. Une antibiothérapie probabiliste a été réalisée chez 75,76% des patients. La mortalité était de 76,74%. Les facteurs de mortalité étaient une durée de ventilation mécanique supérieure à 15 jours et l'âge supérieur à 50 ans.Conclusion :La mortalité secondaire au PAVM demeure élevée. L'identification des deux facteurs pronostiques devrait améliorer la prise en charge ultérieure de tous nouveaux cas


Objectives: To identify the factors of poor prognosis of ventilator-associated lung disease (VAP) in order to improve their management. Patients and method: Prospective, descriptive and analytical study of patients admitted to intensive care at the Angré University Hospital from November 1, 2019 to July 31, 2021 and having presented VAP.Results: We collected 43 patients out of 625 admissions, i.e. 6.88%. The average age was 49.06 years. The sex ratio was 0.38. The main reason for admission was coma with 88.37%. Hypertension and diabetes were the main antecedents. Early VAP accounted for 53.49%. Klebsiella pneumoniae was the main germ. Patients intubated on admission accounted for 79.07%. The average duration of ventilation was 26.95 days and the average duration of hospitalization was 30.8140 days. Probabilistic antibiotic therapy was performed in 75.76% of patients. Mortality was 76.74%. The mortality factors were duration of mechanical ventilation greater than 15 days and age greater than 50 years.Conclusion:Secondary mortality from VAP remains high. The identification of the two prognostic factors should improve the subsequent management of all new cases.
