Generation and characterization of avian IgY antibodies for detecting beta-casein A1 in bovine milk.

Beta-casein is a primary milk protein that constitutes approximately 30% of the casein in bovine milk, with the two most common types in cattle being A1 and A2. The A2 protein differs from the A1 version due to a mutation in the codon at position 67, resulting in a histidine to proline substitution. However, the bioactive peptide, beta-casomorphine-7 (BCM7), which originates from partial proteolysis of the A1 variant, has been linked to several gastrointestinal disorders in humans. Production of A1 beta casein-free products is increasing demand in the milk market, worldwide. This study generated and characterized a polyclonal IgY antibody that specifically recognizes the A1 beta-casein protein present in cow's milk. A commercially available IgY anti-A1 antibody was used as a positive control, and the sensitivity and specificity of both the commercial and produced anti-A1 antibodies were evaluated. The results showed 100% sensitivity and specificity of 100% of the commercial IgY anti-A1. The in-house produced anti-A1 antibody demonstrated a sensitivity of 95.2% and a specificity of 100%, indicating its potential as a reliable and cost effective tool for detecting A1 beta-casein protein in milk samples.

Factors associated with international humanitarian aid appeal for disasters from 1995 to 2015: A retrospective database study.

INTRODUCTION: International humanitarian aid during disasters should be needs-based and coordinated in response to appeals from affected governments. We identify disaster and population factors associated with international aid appeal during disasters and hence guide preparation by international humanitarian aid providers. METHODS: In this retrospective database analysis, we searched the Emergency Events Database for all disasters from 1995 to 2015. Disasters with and without international aid appeals were compared by location, duration, type of disaster, deaths, number of people affected, and total estimated damage. Logistic regression was used to examine the association of each factor with international aid appeal. RESULTS: Of 13,961 disasters recorded from 1995 to 2015, 168 (1.2%) involved international aid appeals. Aid appeals were more likely to be triggered by disasters which killed more people (OR 1.29 [95% confidence interval (CI) 1.02-1.64] log10 persons), affected more people (OR 1.85 [95%CI 1.57-2.18] / log10 persons), and occurred in Africa (OR 1.67 [95%CI 1.06-2.62). Earthquakes (OR 4.07 [95%CI 2.16-7.67]), volcanic activity (OR 6.23 [95%CI 2.50-15.53]), and insect infestations (OR 12.14 [95%CI 3.05-48.35]) were more likely to trigger international aid appeals. International aid appeals were less likely to be triggered by disasters which occurred in Asia (OR 0.46 [95%CI 0.29-0.73]) and which were transport accidents (OR 0.12 [95%CI 0.02-0.89]). CONCLUSION: International aid appeal during disasters was associated with greater magnitude of damage, disasters in Africa, and specific types of disasters such as earthquakes, volcanic activity, and insect infestations. Humanitarian aid providers can focus preparation on these identified factors.

Applying the Haddon Matrix to Frontline Care Preparedness and Response in Asymmetric Warfare.

INTRODUCTION: Asymmetric warfare and the reaction to its threats have implications in the way far-forward medical assistance is provided in such settings. Investments in far-forward emergency resuscitation and stabilization can contribute to saving lives and increase the resilience of health systems. Thus, it is proposed to extend the use of the Haddon Matrix to determine a set of strategies to better understand and prioritize activities to prepare for and set-up frontline care in the form of Trauma Stabilization Points (TSPs). METHODS: An expert consensus methodology was used to achieve the research aim. A small subject matter experts' group was convened to create and validate the content of the Haddon Matrix. RESULTS: The result of the expert group consultations presented an overview of TSP Preparedness and Operational Readiness activities within a Haddon Matrix framework. Main strategies to be adopted within the cycle from pre- to post-event had been identified and presented considering the identified opportunities in the context of the possibility of implementation. Of particular importance was the revision of a curriculum that fits the civilian medical system and facilitates its adaptation to the context and available resources. CONCLUSION: The new framework to enhance frontline care preparedness and response using the Haddon Matrix facilitated the identification of a set of strategies to support frontline health care workers in a more efficient manner. Since the existing approach and tools are insufficient for modern warfare, additional research is needed.

The first life skills intervention to enhance well-being amongst university students in the Arab world: 'Khotwa' pilot study.

Although Life Skills programs showed to improve the psychological and physical wellbeing of individuals, little attention has been paid, worldwide and in the Arab countries in specific to implementing life skills intervention for university students. In this study, we tested the effectiveness of a life skills based health promotion intervention KHOTWA (STEP) in enhancing the wellbeing of university students in Lebanon, a country that faces economic and political instability. This is a quasi-experimental study, with pre and post-test, intervention-control design. Each group was formed of 78 participants studying in a private university in Lebanon. Mixed design was used to address the process and outcomes objectives of the intervention. The program was carried online due to COVID-19 pandemic. Significant differences were observed between the intervention and the control groups for life skills, dietary habits and mental health scores at the 3-month follow-up. For the intervention group, a significant increase was observed in the mean score of each of the following Life Skills subscales: self-care (p = 0.001), work and study (p = 0.013), career and education planning (p = 0.011) and looking forward/goal settings (p < 0.001). Students also achieved a healthier eating habit compared to those in the control group by decreasing their consumption of processed food. There was no significant effect in terms of body mass index (p = 0.827). Also, there was a significant change in the mental health status (p = 0.012) only in the intervention group as its mean score decreased after 3 months of the intervention implementation. This intervention enhances the mental health and promotes healthy habits leading consequently to a better quality of life and more productivity amongst university students. Therefore, such interventions should be replicated in other similar context to improve university students' well-being.

Just-in-Time Training in a Tertiary Referral Hospital During the COVID-19 Pandemic in Italy.

The COVID-19 pandemic is threatening health systems worldwide, requiring extraordinary efforts to contain the virus and prepare health care systems for unprecedented situations. In this context, the entire health care workforce must be properly trained to guarantee an effective response. Just-in-time training has been an efficient solution for rapidly equipping health care workers with new knowledge, skills, and attitudes during emergencies; thus, it could also be an effective training technique in the context of the response to the COVID-19 pandemic. Because of the unexpected magnitude of this health crisis, the health care workforce must be trained in 2 areas: (1) basic infection prevention and control, including public health skills that are the core of population-based health management and (2) disaster medicine principles, such as surge capacity, allocation of scarce resources, triage, and the ethical dilemmas of rationing medical care. This Perspective reports how just-in-time training concepts and methods were applied in a tertiary referral hospital in March 2020, during the COVID-19 pandemic in Northern Italy, one of the hardest hit places in the world. The COVID-19 just-in-time training was designed to provide hospital staff with the competencies they need to work proficiently and safely inside the hospital, including an understanding of the working principles and standard operating procedures in place and the correct use of personal protective equipment. Moreover, this training was intended to address the basic principles of disaster medicine applied to the COVID-19 pandemic. Such training was essential in enabling staff to rapidly attain competencies that most of them lacked because disaster medicine and global health are not included in the curricula of Italian medical and nursing schools. Although a formal evaluation was not performed, this is a useful example of how to create just-in-time training in a large hospital during a crisis of an unprecedented scale.

Addressing Abortion Provider Stigma: A Pilot Implementation of the Providers Share Workshop in Sub-Saharan Africa and Latin America.

CONTEXT: In much of Sub-Saharan Africa and Latin America, abortion is legally restricted, and abortion providers experience stigma and legal jeopardy. The Providers Share Workshop group intervention has been shown to reduce provider stigma in the United States, but has not been evaluated in other settings. METHODS: In 2014-2015, the Providers Share Workshop was adapted and piloted among 59 abortion caregivers from three Sub-Saharan African countries and 93 caregivers from seven Latin American countries. Survey data collected before, directly following and six months after each workshop measured stigma, attitudes, and legal safety and advocacy engagement, using original items and adapted scales. Univariate analyses and baseline pairwise correlations were used to measure changes in outcomes over time, and between demographic characteristics and outcomes. Mixed-effects linear regressions and multivariable models controlling for demographics were used to assess changes in outcomes over time. RESULTS: Six months after workshop participation, total abortion stigma had decreased among caregivers in Sub-Saharan Africa and in Latin America (beta coefficients, -0.2 and -0.4, respectively). Unfavorable attitudes had decreased in Africa (-0.2) but not in Latin America, where attitudes were favorable to start; emotional exhaustion and depersonalization also had decreased in Africa (-2.9 and -1.2), and legal safety had increased (0.8). Increased total abortion stigma was negatively associated with legal safety, in both Africa and Latin America (-1.9 and -0.6), and with legal advocacy in Africa (-1.5). CONCLUSIONS: The Providers Share Workshop is a promising intervention to support the abortion care workforce in Sub-Saharan African and Latin American settings.

RESUMEN Contexto: En gran parte del África subsahariana y América Latina, el aborto está legalmente restringido y los proveedores de servicios de aborto experimentan estigma y riesgo legal. Se ha demostrado que la intervención grupal del Taller de Proveedores para Compartir Experiencias reduce el estigma del proveedor en los Estados Unidos, pero no se ha evaluado en otros entornos. Métodos: Entre 2014 y 2015, el Taller de Proveedores para Compartir Experiencias fue adaptado y puesto a prueba entre 59 proveedores de servicios de aborto de tres países del África subsahariana y 93 proveedores de servicios de siete países latinoamericanos. Los datos de la encuesta recopilados antes, inmediatamente después y seis meses después de cada taller, mediante el uso de elementos originales y escalas adaptadas, midieron el estigma, las actitudes y la seguridad jurídica, así como el compromiso con la defensa y promoción del aborto. Se utilizaron análisis univariados y correlaciones de referencia por pares para medir los cambios en los resultados a través del tiempo y entre la demografía y los resultados. Se utilizaron regresiones lineales de efectos mixtos y modelos multivariables que controlan las variables demográficas para evaluar los cambios en los resultados a través del tiempo. Resultados: Seis meses después de la participación en el taller, el estigma total del aborto había disminuido entre los proveedores en África y América Latina (coeficientes beta, ­0.2 y ­0.4, respectivamente). Las actitudes desfavorables habían disminuido en África (­0.2) pero no en América Latina, donde las actitudes eran favorables para el inicio; el desgste emocional y la despersonalización también habían disminuido en África (­2.9 y ­1.2, respectivamente) y la seguridad legal había aumentado (0.8). El aumento del estigma total del aborto se asoció negativamente con la seguridad jurídica, tanto en África como en América Latina (coeficientes beta, ­1.9 y ­0.6, respectivamente) y con la defensa jurídica en África (­1.5). Conclusiones: El Taller de Proveedores para Compartir Experiencias es una intervención prometedora para apoyar a la fuerza laboral de atención del aborto en entornos de África subsahariana y América Latina.

RÉSUMÉ Contexte: Dans une grande partie de l'Afrique subsaharienne et de l'Amérique latine, l'avortement est limité par la loi et ses prestataires sont en proie à la stigmatisation et au péril judiciaire. Comme l'indiquent les études, l'intervention du groupe Providers Share Workshop réduit cette stigmatisation aux États-Unis; elle n'a cependant pas été évaluée dans d'autres contextes. Méthodes: En 2014­2015, l'atelier Providers Share Workshop a été adapté et piloté auprès de 59 membres du personnel de soins de l'avortement de trois pays d'Afrique subsaharienne et 93 soignants de sept pays d'Amérique latine. Les données d'enquête collectées avant, directement après et six mois après chaque atelier ont mesuré la stigmatisation, les attitudes et l'engagement de sécurité et de défense juridique sur la base des questions originales et d'échelles adaptées. Les changements de résultats au fil du temps, et entre les caractéristiques démographiques et les résultats, ont été mesurés par analyses univariées et par corrélations par paires de référence. Des régressions linéaires à effets mixtes et des modèles multivariés tenant compte des caractéristiques démographiques ont servi à évaluer les changements de résultats au fil du temps. Résultats: Six mois après la participation à l'atelier, la stigmatisation totale de l'avortement s'était réduite parmi le personnel soignant d'Afrique et d'Amérique latine (coefficients bêta de ­0,2 et ­0,4, respectivement). Les attitudes défavorables étaient en baisse en Afrique (­0,2) mais pas en Amérique latine, où les attitudes étaient favorables dès le début; l'épuisement affectif et la dépersonnalisation étaient en baisse aussi en Afrique (­2,9 et ­1,2, respectivement), tandis que la sécurité juridique était en hausse (0,8). Une stigmatisation totale supérieure de l'avortement s'est révélée associée négativement avec la sécurité juridique, en Afrique aussi bien qu'en Amérique latine (coefficients bêta de ­1,9 et ­0,6, respectivement), et avec la défense juridique en Afrique (­1,5). Conclusions: L'atelier Providers Share Workshop est une intervention prometteuse de soutien du personnel de soins de l'avortement en Afrique subsaharienne et en Amérique latine.

Targeting Trypanosoma evansi with disulphide-rich peptides derived from a phage display library.

A phage-display library was generated using a Bus thalamus scorpion toxin (BTK-2) as a peptide scaffold. BTK-2 belongs to the disulfide-rich family of proteins with pronounced structural stability due to the presence of three disulfide bridges that connects antiparallel beta-sheets and one alpha helix. Using BTK-2 as a phage display scaffold, we introduced mutations in five residues located in the alpha-helix and two residues located in the smaller loop, keeping intact the disulfide bridges to create a peptide phage-displayed library with disulfide-rich family properties. The library was subjected to in vivo and in vitro phage display selections against Trypanosoma evansi, the etiological agent of "Surra", a disease that affects a wide range of mammals. The development of T. evansi specific biomarkers is essential to improve diagnostic methods and epidemiological studies leading to a more accurate clinical decision for the treatment of this disease of economic impact for commercial livestock production. In this study, we identified two disulfide-rich peptides targeting T. evansi parasites. Further specificity studies are necessary to investigate the potential of selected peptides as new biomarkers to aid diagnostic and treatment procedures of T. evansi infections.

Stigma and abortion complications: stories from three continents.

Complications from abortion, while rare, are to be expected, as with any medical procedure. While the vast majority of serious abortion complications occur in parts of the world where abortion is legally restricted, legal access to abortion is not a guarantee of safety, particularly in regions where abortion is highly stigmatised. Women who seek abortion and caregivers who help them are universally negatively "marked" by their association with abortion. While attention to abortion stigma as a sociological phenomenon is growing, the clinical implications of abortion stigma - particularly its impact on abortion complications - have received less consideration. Here, we explore the intersections of abortion stigma and clinical complications, in three regions of the world with different legal climates. Using narratives shared by abortion caregivers, we conducted thematic analysis to explore the ways in which stigma contributes, both directly and indirectly, to abortion complications, makes them more difficult to treat, and impacts the ways in which they are resolved. In each narrative, stigma played a key role in the origin, management and outcome of the complication. We present a conceptual framework for understanding the many ways in which stigma contributes to complications, and the ways in which stigma and complications reinforce one another. We present a range of strategies to manage stigma which may prove effective in reducing abortion complications.

Radical parametrectomy after 'cut-through' hysterectomy in low-risk early-stage cervical cancer: Time to consider this procedure obsolete.

OBJECTIVE: The goal of this study is to identify predictive factors in patients with a diagnosis of early-stage cervical cancer after simple hysterectomy in order to avoid a radical parametrectomy. METHODS: A retrospective review was performed of all patients who underwent radical parametrectomy and bilateral pelvic lymphadenectomy at MD Anderson Cancer Center and at the Instituto de Cancerologia Las Americas in Medellin, Colombia from December 1999 to September 2017. We sought to determine the outcomes in patients diagnosed with low-risk factors (squamous, adenocarcinoma or adenosquamous lesions<2cm in size, and invading<10mm) undergoing radical parametrectomy and pelvic lymphadenectomy. RESULTS: A total of 30 patients were included in the study. The median age was 40.4years (range; 26-60) and median body mass index (BMI) was 26.4kg/m2 (range; 17.7-40.0). A total 22 patients had tumors<1cm and 8 had tumors between 1 and 2cm. A total of 6 (33%) of 18 patients had evidence of lymph-vascular invasion (LVSI). No radical parametrectomy specimen had residual tumor, involvement of the parametrium, vaginal margin positivity, or lymph node metastasis. None of the patients received adjuvant therapy. After a median follow-up of 99months (range; 6-160) only one patient recurred. CONCLUSION: Radical parametrectomy may be avoided in patients with low-risk early-stage cervical cancer detected after a simple hysterectomy. Rates of residual disease (parametrial or vaginal) and the need for adjuvant treatments or recurrences are very low.

Outpatient laparoscopic nerve-sparing radical hysterectomy: A feasibility study and analysis of perioperative outcomes.

OBJECTIVE: The goal of our study was to report on the feasibility of outpatient laparoscopic radical hysterectomy in patients with early-stage cervical cancer. METHODS: We included all patients who underwent a laparoscopic radical hysterectomy at the Instituto de Cancerología - Las Americas in Medellin, Colombia, between January 2013 and July 2015. The control group was a similar cohort of patients who were admitted after their surgery. RESULTS: Seventy-six patients were included [outpatient (31) and admitted (45)]. There were no statistically significant differences between groups regarding age, clinical stage, histology, nodal count, need of adjuvant treatment, visual pain scores at discharge or follow up time. All patients underwent a transversus abdominis plane block. The median operative time was 150min (range, 105-240) in the outpatient group vs. 170min (range, 97-300) in the admitted group (p=0.023). The median estimated blood loss was 50ml (range, 20-150) in the outpatient group vs. 120ml (range, 20-1000) in the admitted group (p=0.001). All patients were able to void spontaneously and tolerate a diet before discharge. In patients who were admitted, the median hospital stay was 1day, (range; 1-6), and 39 (87%) were discharged at postoperative day 1. There were 6 postoperative complications, 3 in each group. There were no recurrences in the follow-up period in the outpatient group, and there were 3 (6.6%) recurrences in the admitted group. CONCLUSION: Outpatient laparoscopic radical hysterectomy is feasible and can be performed safely in a developing country in well-selected patients.

Traquelectomía radical laparoscópica en pacientes con cáncer de cuello uterino en estado IB1 en el Instituto de Cancerología - Las Américas, Medellín, Colombia

Objetivo: Revisar nuestra experiencia en traquelectomía radical laparoscópica en cáncer de cérvix en estado temprano. Métodos: Estudio observacional descriptivo retrospectivo de las pacientes que se sometieron a traquelectomía radical laparoscópica en el Instituto de Cancerología - Las Américas, Medellín, Colombia, entre Mayo de 2009 y Enero 2015. Resultados: Se completó satisfactoriamente el procedimiento en 13 pacientes en estadío IB1, 12 (92%) tuvieron tumores menores a 2 cm y una recibió quimioterapia neoadyuvante por un tumor de 3 cm. El tipo histológico más frecuente fue el escamoso en 7 pacientes (54%). En 5 pacientes (38%) no se evidenció enfermedad residual luego del procedimiento. El tiempo quirúrgico promedio fue de 240 min (130-340 min); la mediana de pérdida sanguínea fueron 100 ml (50-200 ml). Dos pacientes tuvieron cistotomía incidental durante la cirugía, reparadas por vía laparoscópica, una de ellas desarrollo una fístula vésico-vaginal que cerró espontáneamente. Ninguna paciente requirió transfusión sanguínea ni conversión a laparotomía. La estancia hospitalaria promedio fue de 1 día (1-3). Dos pacientes requirieron histerectomía laparoscópica. No se han reportado recurrencias ni embarazos con un seguimiento promedio 27,9 meses (8,3-64,4). Conclusión: La traquelectomía radical laparoscópica es factible y se puede realizar de manera segura en un país en desarrollo, en pacientes bien seleccionados, con cáncer de cérvix temprano que desean preservar su fertilidad. Los tiempos de seguimiento aún son cortos para conclusiones definitivas sobre el resultado obstétrico. La seguridad oncológica parece similar a la de la traquelectomía abdominal y/o vaginal.

Objective: To review our experience with laparoscopic radical trachelectomy in patients with early-stage cervical cancer. Methods: We performed a observational descriptive retrospective review of all patients who underwent a laparoscopic radical trachelectomy at the Instituto de Cancerología - Las Americas, Medellin, Colombia, between May 2009 and January 2015. Results: 13 patients completed surgery, 12 patients (92%) were diagnosed as IB1 with tumor size less than 2 cm, and one patient received neoadjuvant chemotherapy due to a 3 cm cervical tumor; histology was squamous cell carcinoma in 7 patients (54%). Five patients (38%) showed no residual disease. The mean surgical time was 240 min (130-340 min); the estimated blood loss was 100 ml (50-200 ml). Two patients had a cystotomy during surgery; one of them developed a vesicovaginal fistula that healed spontaneously. No transfusions were given. No conversions were made. Mean hospital stay 1 day (1-3 day). 2 patients required laparoscopic hysterectomy. To date, no recurrence or pregnancies has been recorded with the median follow up 27.9 months (8.3-64.4 month). Conclusion: Laparoscopic radical trachelectomy is feasible and can be performed safely in a developing country in well-selected patients with early cervical cancer who wish to preserve their fertility. Follow up times are still too short to drive definitive conclusions on obstetric results. The oncological safety appears similar to that of the abdominal trachelectomy and/or vaginal.

Xpert MTB/RIF test performance assay in respiratory samples at real work settings in a developing country.

INTRODUCTION: The Xpert MTB/RIF test detects DNA from Mycobacterium tuberculosis complex and susceptibility to rifampin. It has been evaluated repeatedly under "ideal" conditions including centrifugation of sputum and bronchoalveolar lavage, Ziehl Neelsen (ZN) and auramine/rhodamine staining, as well as with solid and liquid automated culture methods. Results from such evaluations cannot be extrapolated to low-income countries that do not routinely use all these processes. OBJECTIVE: To assess the performance of the Xpert MTB/RIF test in respiratory samples under "real" conditions of work in a low-income country and its correlation with phenotypic susceptibility testing. MATERIALS AND METHODS: We conducted a cross-sectional study to assess the performance of the Xpert MTB/RIF test in =12 year-old patients with suspected pulmonary tuberculosis. In routine sample processing at the Hospital we do not use sputum centrifugation, staining with auramine/rhodamine or automated liquid culture. RESULTS: We screened 152 patients of whom 108 were eligible for the study and 103 were included in the analysis; 34% of the samples were positive. The overall test sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 91%, 92%, 83% and 96%, respectively. In ZN-negative samples the sensitivity, specificity, PPV and NPV were 87%, 91%, 68% and 97%, respectively. The results of sensitivity and resistance to rifampin were concordant with susceptibility testing using the multiple proportions method (kappa=1, p<0.0001). CONCLUSIONS: The Xpert MTB/RIF test overall performance was similar to the one achieved under ideal conditions. Its performance in ZN-negative samples was better under "real" conditions of work in a low-income country.

Radical trachelectomy in early-stage cervical cancer: A comparison of laparotomy and minimally invasive surgery.

OBJECTIVES: Radical trachelectomy is considered standard of care in patients with early-stage cervical cancer interested in future fertility. The goal of this study was to compare operative, oncologic, and fertility outcomes in patients with early-stage cervical cancer undergoing open vs. minimally invasive radical trachelectomy. METHODS: A retrospective review was performed of patients from four institutions who underwent radical trachelectomy for early-stage cervical cancer from June 2002 to July 2013. Perioperative, oncologic, and fertility outcomes were compared between patients undergoing open vs. minimally invasive surgery. RESULTS: A total of 100 patients were included in the analysis. Fifty-eight patients underwent open radical trachelectomy and 42 patients underwent minimally invasive surgery (MIS=laparoscopic or robotic). There were no differences in patient age, body mass index, race, histology, lymph vascular space invasion, or stage between the two groups. The median surgical time for MIS was 272min [range, 130-441min] compared with 270min [range, 150-373min] for open surgery (p=0.78). Blood loss was significantly lower for MIS vs. laparotomy (50mL [range, 10-225mL] vs. 300mL [50-1100mL]) (p<0.0001). Nine patients required blood transfusion, all in the open surgery group (p=0.010). Length of hospitalization was shorter for MIS than for laparotomy (1day [1-3 days] vs. 4days [1-9 days]) (p<0.0001). Three intraoperative complications occurred (3%): 1 bladder injury, and 1 fallopian tube injury requiring unilateral salpingectomy in the MIS group and 1 vascular injury in the open surgery group. The median lymph node count was 17 (range, 5-47) for MIS vs. 22 (range, 7-48) for open surgery (p=0.03). There were no differences in the rate of postoperative complications (30% MIS vs. 31% open surgery). Among 83 patients who preserved their fertility (33 MIS vs. 50 open surgery), 34 (41%) patients attempted to get pregnant. Sixteen (47%) patients were able to do so (MIS: 2 vs. laparotomy: 14, p=0.01). The pregnancy rate was higher in the open surgery group when compared to the MIS group (51% vs. 28%, p=0.018). However, median follow-up was shorter is the MIS group compared with the open surgery group (25months [range, 10-69] vs. 66months [range, 11-147]). To date, there has been one recurrence in the laparotomy group and none in the MIS group. CONCLUSIONS: Our results suggest that radical trachelectomy via MIS results in less blood loss and a shorter hospital stay. Fertility rates appear higher in patients undergoing open radical trachelectomy.

Immediate radical trachelectomy versus neoadjuvant chemotherapy followed by conservative surgery for patients with stage IB1 cervical cancer with tumors 2cm or larger: A literature review and analysis of oncological and obstetrical outcomes.

Radical trachelectomy is the treatment of choice in women with early-stage cervical cancer wishing to preserve fertility. Radical trachelectomy can be performed with a vaginal, abdominal, or laparoscopic/robotic approach. Vaginal radical trachelectomy (VRT) is generally not offered to patients with tumors 2cm or larger because of a high recurrence rate. There are no conclusive recommendations regarding the safety of abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) in such patients. Several investigators have used neoadjuvant chemotherapy in patients with tumors 2 to 4cm to reduce tumor size so that fertility preservation may be offered. However, to our knowledge, no published study has compared outcomes between patients with cervical tumors 2cm or larger who underwent immediate radical trachelectomy and those who underwent neoadjuvant chemotherapy followed by radical trachelectomy. We conducted a literature review to compare outcomes with these 2 approaches. Our main endpoints for evaluation were oncological and obstetrical outcomes. The fertility preservation rate was 82.7%, 85.1%, 89%; and 91.1% for ART (tumors larger than >2cm), ART (all sizes), NACT followed by surgery and VRT (all sizes); respectively. The global pregnancy rate was 16.2%, 24% and 30.7% for ART, VRT, and NACT followed by surgery; respectively. The recurrence rate was 3.8%, 4.2%, 6%, 7.6% and 17% for ART (all sizes), VRT (all sizes), ART (tumors>2cm), NACT followed by surgery, and VRT (tumors>2cm). These outcomes must be considered when offering a fertility sparing technique to patients with a tumor larger than 2cm.

Se llevó a cabo un estudio transversal para evaluar el rendimiento de la prueba Xpert MTB/RIF en pacientes =12 años con sospecha de tuberculosis pulmonar. En el procesamiento rutinario de muestras en el Hospital del estudio no se usa la centrifugación del esputo, la tinción con auramina-rodamina ni el cultivo líquido automatizado. Resultados. Se incluyeron 152 pacientes, de los cuales 108 eran elegibles y 103 se incluyeron en el análisis. El 34 % de las muestras fueron positivas; la sensibilidad de la prueba fue de 91 %, la especificidad de 92 %, el valor diagnóstico positivo de 83 % y el valor diagnóstico negativo global de 96 %. En las muestras negativas con Ziehl Neelsen, la sensibilidad fue de 87 %, la especificidad de 91 % y los valores diagnósticos positivo y negativo alcanzaron 68 y 97 %, respectivamente. Los resultados de sensibilidad o resistencia a la rifampicina concordaron con los de la prueba fenotípica de sensibilidad (valor de kappa=1, p<0,0001). Conclusiones. El rendimiento global de la prueba fue similar al obtenido bajo condiciones "ideales". En las muestras negativas con Ziehl Neelsen se obtuvo un mejor rendimiento en las condiciones "reales" de trabajo de un país de bajos ingresos.

Neumonitis intersticial linfoidea en niños infectados por el virus de inmunodeficiencia humana-1 en zona de alta prevalencia de tuberculosis pulmonar / Lymphoid interstitial pneumonitis in children infected with type 1 human immunodefi ciency virus from areas with high pulmonary tuberculosis prevalence

Antecedentes : Poco se sabe sobre la neumonitis intersticial linfoidea (NIL) en niños con infección por el virus de inmunodeficiencia humana-1 (VIH-1) Objetivos: Describir las características clínicas y patológicas de NIL en niños infectados por VIH-1 en un centro de referencia para VIH pediátrico en Cali (Colombia). Métodos: Se llevó a cabo una descripción de serie de casos de NIL basados en revisión retrospectiva de historias clínicas de todos los casos de niños con enfermedad pulmonar crónica y LIP confirmada por biopsia entre los años 2001 y 2012. Resultados y conclusiones: Diez de 12 casos con NIL fueron confirmados por biopsia pulmonar. Se observó una respuesta clínica y de función respiratoria luego del tratamiento con prednisona, excepto en un caso que presentó tos persistente. No se encontraron casos de tuberculosis pulmonar (TP) en nuestra serie y el papel de la biopsia pulmonar fue crítico para alcanzar un diagnóstico preciso.

Background: Little is known about Lymphoid Interstitial Pneumonitis (LIP) in children with HIV infection. Aims: To describe the clinical and pathological characteristics of LIP in infected children in a referral center for pediatric HIV in Cali (Colombia). Methods: Case series based on retrospective analysis of clinical charts among HIV-infected children with chronic lung disease and lung-biopsy proven LIP between the years 2001 and 2012. Results and conclusions: 10 of 12 cases of LIP were confirmed by lung biopsy. Significant clinical and respiratory functional improvement was obtained in all cases after prednisone therapy, excepting one child who presented persistent cough. No case of pulmonary TB was detected in our cohort. Lung biopsy was critical to obtain an accurate diagnosis.

Brote hospitalario de Achromobacter denitrificans relacionado con el uso de clorhexidina contaminada / Achromobacter denitrificans hospital outbreak associated with the use of contaminated chlorhexidine

El objetivo de este artículo es describir una serie de casos de pacientes con pseudobacteriemia causada por Achromobacter denitrificans, germen aislado a partir de los hemocultivos de 14 pacientes hospitalizados en una institución de alta complejidad de Medellín. Los casos estuvieron asociados con el uso de clorhexidina al 4 % en jabón contaminado. Todos los pacientes recibieron antibióticos con resultados favorables, posiblemente debido a la baja virulencia de este microorganismo y a las medidas oportunas adoptadas por el Grupo de Control de Infecciones del hospital.

The aim of this paper is to describe a case series of pseudobacteremia caused by Achromobacter denitrificans, isolated from blood cultures from 14 hospitalized patients in a tertiary care institution in Medellín. The cases were associated with the use of contaminated 4% chlorhexidine soap. All patients received antibiotic treatment and had favorable results, possibly because of the low virulence of this organism and the timely measures taken by the hospital infections control group.
