Health-Related Quality of Life Long-Term Study in Lung Transplant Patients: A Single-Center Experience.

INTRODUCTION: Health-related quality of life (HRQL) assessment plays a crucial role in the follow-up care of lung transplanted (LTx) patients. Previous reports have indicated that the HRQL achieved by these patients is often poorer compared to that of healthy individuals. However, the factors contributing to this lower HRQL remain unclear. This prospective study aimed to assess the effectiveness of using both a generic and a disease-specific HRQL instrument in evaluating the outcomes of patients who have undergone LTx. METHODS: A total of 111 LTx patients were enrolled in the study, with 88 survivors completing the 5-year follow-up and 23 nonsurvivors identified within the first 3 y. Among the participants, 84 underwent double LTx, while 27 received a single LTx. Patients were interviewed before LTx, at 6 mo post-transplantation, and annually thereafter. Two validated instruments were utilized: the Euro quality of life five dimensions, a generic measure, and the St. George's Respiratory Questionnaire (SGRQ), a disease-specific questionnaire. RESULTS: The study showed significant improvements in Euro Quality of Life five Dimensions scores from 6 mo after LTx. Specifically, the percentage of patients without Mobility problems increased from 23% before LTx to 71% at 5 y (P = <0.001), while the ability to self-care improved from 48% to 100% (P = <0.001). The ability to carry out usual activities improved from 13% to 86% (P = <0.001), and the proportion of patients without anxiety and depression increased from 50% to 86% (P > 0.004). However, there was no significant improvement observed in Pain, with only a slight reduction from 57% to 42.8% (P = 0.22). The SGRQ also showed improvements in all dimensions (symptoms, impact, activities) (P < 0.001). However, by the fifth year, the HRQL scores remained below normal reference values. Chronic graft dysfunction was associated with a decline in SGRQ scores. Bilateral LTx patients exhibited better SGRQ scores compared to unilateral LTx patients from the first year post-transplantation. Notably, there were no differences in scores between nonsurvivors and survivors. CONCLUSIONS: The study highlights the long-term improvement in HRQL among LTx patients, with greater improvements observed in physical dimensions compared to psychological dimensions. Bilateral LTx was associated with better SGRQ scores than unilateral LTx, and chronic graft dysfunction primarily affected SGRQ scores. These findings underscore the importance of utilizing both generic and specific HRQL instruments in assessing LTx outcomes.

Lung Transplantation in Controlled Donation after Circulatory-Determination-of-Death Using Normothermic Abdominal Perfusion.

The main limitation to increased rates of lung transplantation (LT) continues to be the availability of suitable donors. At present, the largest source of lung allografts is still donation after the neurologic determination of death (brain-death donors, DBD). However, only 20% of these donors provide acceptable lung allografts for transplantation. One of the proposed strategies to increase the lung donor pool is the use of donors after circulatory-determination-of-death (DCD), which has the potential to significantly alleviate the shortage of transplantable lungs. According to the Maastricht classification, there are five types of DCD donors. The first two categories are uncontrolled DCD donors (uDCD); the other three are controlled DCD donors (cDCD). Clinical experience with uncontrolled DCD donors is scarce and remains limited to small case series. Controlled DCD donation, meanwhile, is the most accepted type of DCD donation for lungs. Although the DCD donor pool has significantly increased, it is still underutilized worldwide. To achieve a high retrieval rate, experience with DCD donation, adequate management of the potential DCD donor at the intensive care unit (ICU), and expertise in combined organ procurement are critical. This review presents a concise update of lung donation after circulatory-determination-of-death and includes a step-by-step protocol of lung procurement using abdominal normothermic regional perfusion.

Psychosocial interventions reduce cortisol in breast cancer patients: systematic review and meta-analysis.

Introduction: Cancer initiation, progression and recurrence are intricate mechanisms that depend on various components: genetic, psychophysiological, or environmental. Exposure to chronic stress includes fear of recurrence that can affect biological processes that regulate immune and endocrine systems, increase cancer risk, and influence the survival rate. Previous studies show that psychological interventions might influence the level of cortisol that has been extensively used as a biomarker for measuring hypothalamic-pituitary-adrenal axis functioning and body's immunity response. This meta-analysis aimed to provide a quantitative scrutiny of the effect of certain types of psychosocial interventions on cortisol as a neuroendocrine biomarker in saliva or blood and might predict breast cancer (BC) progression. Methods: A literature search was performed in the following databases: PubMed, The Cohrane Library, Scopus, WOS, PsychInfo, Google Scholar, Ovid Science Direct. After methodical selection of originally generated 2.021 studies, the search yielded eight articles that met inclusion criteria. All these studies explored effects of psychosocial interventions that measured cortisol in total of 366 participants with BC, stages 0-IV, in randomized control trial or quasi experimental study design setting. We applied random effects model to conduct meta-analyses on the parameters of salivary and plasma cortisol and used PRISMA Guidelines as validated methodology of investigation to report the results. Results: Eight studies selected for meta-analysis have shown the reduction of cortisol level due to applied psychosocial intervention. The random effects model showed that interventions produced large effect sizes in reductions of cortisol in blood (Cohen's d = -1.82, 95% Confidence Interval (CI): -3.03, -0.60) and slightly less in saliva (d = -1.73, 95%CI: -2.68, -0.78) with an overall effect of d = -1.76 (95%CI: -2.46, -1.07). Conclusion: Our study concluded that certain types of psychosocial interventions reduce cortisol (indicator of chronic stress) in patients with BC. Application of specific psychosocial support as adjuvant non-invasive therapy for affected females with BC at all phases of treatment could contribute to more cost-effective health care.

Effect of Long-Term Use of Alcohol-Containing Handwashing Gels on the Biofilm-Forming Capacity of Staphylococcus epidermidis.

The spread of coronavirus disease 2019 (COVID-19) has promoted the use of hand sanitizers among the general population as recommended by health authorities. Alcohols, which are used in many hand sanitizers, have been shown to promotes the formation of biofilms by certain bacteria and to increase bacterial resistance to disinfection. We investigated the effect of continued use of alcohol-based gel hand sanitizer on biofilm formation by the Staphylococcus epidermidis resident strain isolated from the hands of health science students. Hand microbes were counted before and after handwashing, and the ability to produce biofilms was investigated. We found that 179 (84.8%) strains of S. epidermidis isolated from hands had the ability to form biofilm (biofilm-positive strains) in an alcohol-free culture medium. Furthermore, the presence of alcohol in the culture medium induced biofilm formation in 13 (40.6%) of the biofilm-negative strains and increased biofilm production in 111 (76.6%) strains, which were classified as low-grade biofilm-producing. Based on our findings, there is no clear evidence that the continued use of alcohol-based gels results in the selection of strains with the capacity to form biofilms. However, other disinfectant formulations that are more commonly used in clinical settings, such as alcohol-based hand-rub solutions, should be tested for their long-term effects.

Lung Transplantation for Multiple Giant Hamartomas: First Case Report and Review of the Literature.

BACKGROUND: To assess lung transplant as a solution for a rare complication of giant lung hamartoma, in which surgical resection was discouraged because of severe underlying chronic lung disease. METHODS: A 54-year-old woman had an episode of severe acute hemoptysis. Imaging techniques showed 2 masses in the right lung as hamartomas and severe pulmonary emphysema. After resolution of the acute episode of hemoptysis, the case could have been solved with a right pneumonectomy; however, a single-lung transplant was performed because of the underlying chronic obstructive pulmonary disease. RESULTS: The outcome of the surgery was satisfactory, although a second operation was required because of bleeding. The patient was discharged and currently has a good quality of life, with no recurrence of the disease. The pathologic anatomy of the surgical specimen confirmed the diagnosis of multiple giant hamartomas. CONCLUSIONS: Lung transplant could be a feasible procedure to treat life-threatening complications of benign tumors in selected patients with pulmonary end-stage disease.

Comprehensive Sexually Transmitted Infection Screening and Testing Interventions in a Predominantly Heterosexual Population with HIV at a Health Center.

In the United States, sexually transmitted infections (STIs) have remained elevated for the fifth consecutive year from 2015 to 2019. There is a need to implement standardization of the US Centers for Disease Control and Prevention STI screening and testing recommendations. Higher STI incidence populations such as people with HIV, men who have sex with men, and adolescents and young adults, are frequently not screened and tested for bacterial STIs as recommended. Federally qualified health centers (FQHCs) have the potential to deliver STI services for at-risk individuals as a routine component of primary care. Comprehensive sexual histories using audio computer-assisted self-interview software on electronic devices were done at each clinic visit at a FQHC. Extragenital site testing for chlamydia and gonorrhea, and blood drawn for syphilis testing was completed onsite based on the sexual history responses. Out of 432 eligible clients, 230 clients consented to having their data used for evaluation in this study. Sexual orientation was reported as heterosexual or straight by 86.5% (n = 199), 10.9% (n = 25) as gay/lesbian/same-sex loving, and 2.6% (n = 6) as bisexual or pansexual. Specimen collection took place over a 16-month period and included 80% (n = 855) urine, 13% (n = 140) pharyngeal, and 6.4% (n = 68) rectal samples. Positivity rates included 10% (n = 7) rectal, 6% (n = 8) pharyngeal, and 2% (n = 20) urine samples. Findings identified higher positivity rates among pharyngeal and rectal specimens compared to urogenital specimens. The feasibility of implementing a comprehensive STI screening and testing process in a FQHC is attainable and beneficial.

Gastroesophageal Reflux and Esophageal Motility Disorder After Lung Transplant: Influence on the Transplanted Graft.

BACKGROUND: Esophageal pathology has been identified as a bad prognostic factor in lung transplantation (LTx). This study aims to assess the esophageal disorders present post-LTx, under treatment with proton pump inhibitors, and their putative impact on the graft. METHODS: Prospective, observational study of LTx patients. Digestive factors were assessed by manometry and pH-metry at 6 months post-LTx and under proton pump inhibitor treatment. We assessed the association between esophageal disorders and graft function and acute rejection (AR) and chronic lung allograft dysfunction (CLAD). RESULTS: Out of 76 post-LTx patients, 27% showed gastroesophageal reflux disease (GERD), 55% showed inadequate gastric inhibition, and 59% showed esophageal motility disorders (EMDs). We observed a greater incidence of AR from 3 months post-LTx in the presence of EMD (P ≤ .05). No significant differences were observed in GERD or EMD prevalence or in survival between patients with or without CLAD. The maximum forced expiratory volume in 1 second (FEV1) achieved after bilateral LTx was significantly (P = .022) lower in patients with EMD vs without EMD. CONCLUSION: At 6 months post-LTx, there is a high percentage of esophageal disorders (GERD and EMDs). No esophageal disorder is associated with CLAD or with survival, although EMDs are associated with a greater incidence of AR and lower graft function.

The effect of immediate postoperative Boussignac CPAP on adverse pulmonary events after thoracic surgery: A multicentre, randomised controlled trial.

BACKGROUND: The effectiveness of prophylactic continuous positive pressure ventilation (CPAP) after thoracic surgery is not clearly established. OBJECTIVE: The aim of this study was to assess the effectiveness of CPAP immediately after lung resection either by thoracotomy or thoracoscopy in preventing atelectasis and pneumonia. DESIGN: A multicentre, randomised, controlled, open-label trial. SETTINGS: Four large University hospitals at Madrid (Spain) from March 2014 to December 2016. PATIENTS: Immunocompetent patients scheduled for lung resection, without previous diagnosis of sleep-apnoea syndrome or severe bullous emphysema. Four hundred and sixty-four patients were assessed, 426 were randomised and 422 were finally analysed. INTERVENTION: Six hours of continuous CPAP through a Boussignac system versus standard care. MAIN OUTCOME MEASURES: Primary outcome: incidence of the composite endpoint 'atelectasis + pneumonia'. Secondary outcome: incidence of the composite endpoint 'persistent air leak + pneumothorax'. RESULTS: The primary outcome occurred in 35 patients (17%) of the CPAP group and in 58 (27%) of the control group [adjusted relative risk (ARR) 0.53, 95% CI 0.30 to 0.93]. The secondary outcome occurred in 33 patients (16%) of the CPAP group and in 29 (14%) of the control group [ARR 0.92, 95% CI 0.51 to 1.65]. CONCLUSION: Prophylactic CPAP decreased the incidence of the composite endpoint 'postoperative atelectasis + pneumonia' without increasing the incidence of the endpoint 'postoperative persistent air leaks + pneumothorax'.

Thoracotomy Wound Dehiscence After Lung Transplant Is an Effective Surgical Solution: A Case Report.

Post-thoracotomy wound dehiscence after a lung transplant carries with it morbidity in the postoperative period. While this complication has been widely reported in the literature after a clamshell incision, the thoracotomy dehiscence's surgical solution has not received much emphasis. We present an original technical solution to deal with this complication, performed successfully in a 62-year-old woman diagnosed as having idiopathic pulmonary hemosiderosis after a single lung transplant. This surgical treatment consists of necrotic rib tissue removal, pleural effusion drainage, pulmonary adhesion removal, and chest wall defect reparation with bioabsorbable mesh. This operative technique results safe and effective for thoracotomy dehiscence reparation.

Prevalence of Chronic Diseases among International Travelers Seeking Pretravel Medical Advice in 2018 at Malaga, Spain.

Travelers with preexisting diseases or chronic conditions may be more susceptible to travel-related health risks. They may, therefore, require more attention from specialist travel medicine providers. Our objective was to examine a group of international travelers in Malaga, Spain, quantify the proportion of travelers suffering from chronic conditions, and understand the characteristics of this group. A representative sample of travelers requesting pretravel medical advice at one travel clinic were asked about their preexisting chronic conditions and any immunosuppression. Additional demographic variables were used in an analysis of bivariate correlations. We used a binary logistic regression analysis to identify relationships between independent variables (age, gender, type of trip, travel duration, and destination) and the presence or absence of chronic conditions in travelers. Of the sample of 1,196 travelers, 258 (21.6%) reported having preexisting chronic conditions and 72 (6%) had two or more chronic conditions. Twenty-four of the travelers with chronic conditions (9%) were immunocompromised because of the disease or treatment. The two most common chronic conditions were cardiovascular disease and chronic respiratory conditions (36.8% and 17.1%, respectively). The chronic condition increased by 6.7% for every year of increased age. Travelers with chronic conditions are older, travel mainly to visit friends and relatives, and take shorter trips. More than half of travelers visiting (55.8%) needed more attention from the travel medicine practitioner because of their preexisting chronic conditions, age, or type of travel. Surveillance data based on the population of people traveling would be helpful to provide better advice to travelers.

Pneumonia versus graft dysfunction as the cause of acute respiratory failure after lung transplant: a 4-year multicentre prospective study in 153 adults requiring intensive care admission.

We aimed to assess the main causes of intensive care unit (ICU) readmissions in lung transplant adults and to identify independent predictors of ICU mortality (primary end-point).This Spanish five-centre prospective cohort study enrolled all lung transplant adults with ICU readmissions after post-transplant ICU discharge between 2012 and 2016. Patients were followed until hospital discharge or death.153 lung transplant recipients presented 174 ICU readmissions at a median (interquartile range) of 6 (2-25) months post-transplant. Chronic lung allograft dysfunction was reported in 39 (25.5%) recipients, 13 of whom (all exitus) had restrictive allograft syndrome (RAS). Acute respiratory failure (ARF) (110 (71.9%)) was the main condition requiring ICU readmission. Graft rejection (six (5.4%) acute) caused only 12 (10.8%) readmissions whereas pneumonia (56 (36.6%)) was the main cause (50 admitted for ARF and six for shock), with Pseudomonas aeruginosa (50% multidrug resistant) being the predominant pathogen. 55 (35.9%) and 69 (45.1%) recipients died in the ICU and the hospital, respectively. Bronchiolitis obliterans syndrome (BOS) stage 2 (adjusted OR (aOR) 7.2 (95% CI 1.0-65.7)), BOS stage 3 (aOR 13.7 (95% CI 2.5-95.3)), RAS (aOR >50) and pneumonia at ICU readmission (aOR 2.5 (95% CI 1.0-7.1)) were identified in multivariate analyses as independent predictors of ICU mortality. Only eight (5.2%) patients had positive donor-specific antibodies prior to ICU readmission and this variable did not affect the model.ARF was the main condition requiring ICU readmission in lung transplant recipients and was associated with high mortality. Pneumonia was the main cause of death and was also an independent predictor. RAS should receive palliative care rather than ICU admission.

Trends in the travelers' demand for pre-travel medical advice at a Spanish International Vaccination Center between 2000 and 2017.

Crises and disasters affect the numbers of people traveling either for tourism or other reasons. Many studies have been published on the effects of such events on travel, especially on tourism, and based on the arrivals or departures of travelers to or from countries. Our aim was to assess the influence of these events on the demand for pre-travel medical consultation in an International Vaccination Centre (IVC). Data on 94683 international travelers who visited 113529 international destinations attended at the IVC of Malaga (Spain) during 2000-2017 were studied. A descriptive and time series analyses was conducted. The demand to IVC was 3.47 times higher in 2017 than in 2000. The increase has not been the same for all destinations: Travel to South-East Asia and Western Pacific World Health Organization (WHO) regions has multiplied by 10, while in the same period, Africa WHO region has declined from 36% to 20% of total demand. Thailand, India and Brazil were the countries with the highest demand (21% of all pre-travel consultations). We found out three periods, concurrent with some socioeconomic or health events, in which the number of travellers attend decline with respect to the previous years, or the growth was very slow. Growth in the demand for pre-travel medical advice in parallel with a foreseeable increase in the number of travelers is expected. Pre-travel medical services must be adapted to this increase. This study of the trend of demand for pre-travel medical information should new related problems to travel to be identified and quantified, and should assist improvement of policies and programs aimed at care of travelers.

Carbapenem resistance in Acinetobacter baumannii is associated with enhanced survival on hospital fabrics.

The success of Acinetobacter baumannii as an emerging organism is probably linked to its high resistance to adverse environmental conditions. This study was conducted to analyze the association between some factors that may favor the dissemination of A. baumannii clinical isolates. A total of 47 clinical strains of A. baumannii were evaluated to carbapenem, the ability to produce biofilm, the susceptibility to some antiseptics, and the survival time on cotton fabrics. Most of the isolates were resistant to carbapenem (72.3%), produced biofilm (83%), and survived more than 7 (51%) days on fabrics. A significant association between decreased susceptibility to antiseptics containing chlorhexidine or triclosan and carbapenem resistance and survival on fabrics could be observed. The resistance to carbapenem was significantly associated with survival on fabric, but not with the ability to form biofilm. The survival of the isolates on fabric was not associated with the ability to produce biofilms. Characteristics, such as resistance to antibiotics, ability to form biofilm, and survival on dry surfaces, probably contribute to the proliferation of this organism when selected in the hospital environment and can partly explain its success as responsible for nosocomial infection.

Fluorescence assay for evaluating microbicidal activity of hand antiseptics.

We developed a fluorescent ß-d-glucuronidase activity (BGA)-based assay for detecting and quantifying Escherichia coli in samples to assess the biocide efficacy of hand antiseptics. The fluorescence level is proportional to the number of viable E. coli organisms present. We compared our assay results to those of the E. coli plate count method specified by the European standard for testing hygienic hand rub disinfectant products (EN1500). The plate count method requires excessive handling and materials and is not valid if the number of organisms per plate is too low or high for counting in many of the samples. We optimized the fluorescent assay based on the cleavage of 4-methylumbelliferyl-ß-d-glucuronide by adding 4-nitrophenyl-ß-d-glucuronide, a nonfluorogenic BGA substrate, to induce glucuronidase activity and reduce assay time. Furthermore, our method can be automated and eliminates the need for multiple dilutions. Fluorescence was temporally monitored, and the time required to reach a specific value of fluorescence was correlated with the initial number of viable E. coli organisms on the samples. There was a positive correlation (P < 0.05) with a high correlation coefficient (R(2) = 0.82) between the E. coli counts by plate count and fluorescence methods. Reported effects in fluorescent BGA were compared to the EN1500 plate count method with five hand disinfectants. We found our method more advantageous, because it was as sensitive as the EN1500 method, requires less time to complete, and is less expensive and less laborious than conventional plating techniques.

Persistence of nosocomial bacteria on 2 biocidal fabrics based on silver under conditions of high relative humidity.

BACKGROUND: The survival of pathogenic microorganism on fabrics in the health care environment has a important role in nosocomial infections. The use of biocidal fabrics and surfaces could reduce the prevalence of the microorganisms in the hospital environment. METHODS: In this study, the persistence of nosocomial bacteria on 2 fabrics containing biocidal fibers (BF) in the long term following desiccation and subsequent storage was examined at 40% and 90% relative humidity (RH). RESULTS: Very few strains survived more than 7 days at 40% RH on fabrics containing 67% BF, and only strains of Acinetobacter baumanii and Pseudomonas aeruginosa survived on fabric containing 100% BF. None of the strains tested survived 14 days on the 2 fabrics, 67% or 100% BF, under these environmental conditions. In contrast, at higher RH (∼90%), most of the strains tested showed prolonged survival on both fabrics, and all strains of Klebsiella pneumoniae, Enterobacter aerogenes, and A baumannii survived for more than 14 days; however, in a Petri dish, most of the microorganisms tested showed a higher survival even at 28 days. The gram-positive cocci and A baumannii were the most persistent bacteria on the Petri dish. CONCLUSIONS: This study emphasizes the effect of RH on the survival of nosocomial bacteria on 2 commercially available fabrics containing biocide. Evidence of the clinical efficacy of these BF-containing fabrics is lacking.

El plan de alta de enfermería y su impacto en la disminución de reingresos hospitalario / The nursing discharge plan and its impact on the reduction of hospital readmissions

En 1984 surgió el plan de alta en enfermería en Estados Unidos. Éste fue incluido dentro del sistema Medicare con el propósito de reducir los costos del sistema de salud, por lo que este se extendió rápidamente a Europa y América Latina. En México existen pocos estudios sobre al plan de alta en enfermería, por lo que es necesario evaluar la trascendencia y el impacto de su aplicación. material y métodos: Se realizó un estudio transversal, descriptivo y cuantitativo en un hospital de tercer nivel. La población de estudio fueron las enfermeras con licenciatura del turno matutino. El instrumento de recolección estuvo dividido en cuatro apartados (datos generales, elaboración y contenido del plan, así como el impacto de su aplicabilidad). Resultados: Las recomendaciones del plan de alta se centran en: los medicamentos, los signos y síntomas de alarma, los cuidados en el hogar y las medidas higiénico-dietéticas con 81%. Los profesionales de enfermería lo aplican de forma oral y escrita en 79%. Más de 50% no registra esta actividad en el expediente clínico. Su aplicación contribuye con el derecho que tienen los pacientes de estar informados, además del impacto en los reingresos hospitalarios. Conclusiones: La aplicación del plan de alta en enfermería es una de las formas para fomentar la reintegración del paciente a la sociedad, ya que nos proporciona una visión completa, rápida y veraz del estado de salud del paciente.

In 1984, there is the nursing discharge plan in the U.S. and this is included in the Medicare system, in order to reduce costs in the health system, so this quickly spread to Europe and Latin America. In Mexico there are few studies on the Nursing discharge plan, so it is necessary to evaluate the significance and impact of the implementation. material and methods: We conducted a cross-sectional, descriptive, quantitative, in a tertiary hospital. The study population consisted of nurses with bachelor’s morning shift. The survey instrument was divided into four sections (general information, preparation and content of the plan and the impact of its applicability. Results: The plan’s recommendations focus on high.
