Antimicrobial peptide CAMA-syn expressed in pulmonary epithelium by recombination adenovirus inhibited the growth of intracellular bacteria.

BACKGROUND: Intracellular bacteria, especially Mycobacterium tuberculosis, are important pathogenic microorganisms that endanger human health. Purified and synthesized cecropin A-magainin 2 (CAMA-syn) can exhibit a higher antibacterial activity and lower cytotoxicity. To enhance such antimicrobial potential, it would be desirable to deliver CAMA-syn expressed in lung epithelial cells by an adenovirus vector using gene therapy. METHODS: A549 cells in vitro and lung epithelial cells in vivo were used to express CAMA-syn by transducing recombinant adenovirus Ad-SPC-CAMA/GFP, and the expression of CAMA-syn was determined by a reverse transcriptase-polymerase reaction (RT-PCR) and immunofluorescence. The antimicrobial activity in cells was investigated by colony-forming rate and growth curve. Forty Kunming mice of a Bacillus Calmette-Guerin (BCG) infection animal model were randomly divided into three groups: adenoviruses delivery of Ad-SPC-CAMA/GFP, Ad-CMV-CAMA/GFP and empty-virus Ad-CMV-GFP. The expression of CAMA-syn in mice was confirmed by RT-PCR and immunofluorescence. After tracheal injection of adenoviral vector for 3 days, lungs from the mouse model were extracted and homogenized for detection of colony-forming efficiency. RESULTS: CAMA-syn expressed in lung epithelial cells A549 conferred antimicrobial activity against a series of bacteria, including Salmonella abortusovis and BCG. The results obtained in vivo showed that the colony-forming rate of Ad-SPC-CAMA/GFP (74.54%) and Ad-CMV-CAMA/GFP (62.31%) transduced into mice was significantly lower than that of the control group. CONCLUSIONS: Lung epithelial-specific expression of antimicrobial peptide CAMA-syn mediated by adenovirus suppressed the growth of intracellular bacteria, providing a promising approach for the control of refractory intracellular infection.

Impact of head of bed elevation in symptoms of patients with gastroesophageal reflux disease: a randomized single-blind study (IBELGA). / Impacto de la elevación de la cabecera de la cama en los síntomas de pacientes con enfermedad por reflujo gastroesofágico: estudio aleatorizado simple-ciego (IBELGA).

BACKGROUND: The clinical impact of head-of-bed elevation in patients with gastro-oesophageal reflux disease is unclear, because of inconsistency and methodological limitations of previous studies. PATIENTS AND METHODS: A randomised single-blind single-centre controlled clinical trial with a 2x2 cross-over design, in 39 pharmacologically treated patients with gastro-oesophageal reflux disease. Active intervention was to use a head-of-bed-elevation of 20cm for 6 weeks and then to sleep without inclination for 6 additional weeks, with a wash-out of 2 weeks between periods. The primary outcome was a change ≥10% in RDQ score and secondary outcomes were a change ≥10% in SF-36 score, patient preference and frequency of adverse events. RESULTS: 27 (69.2%) patients who used the intervention reached the primary outcome vs 13 (33.3%) patients in the control group (RR: 2.08; 95 CI%: 1.19 - 3.61). No effect was found in SF-36 score (RR: 1.11; 95% CI: 0.47 - 2.60). Preference favouring the intervention was 77.1% and adverse event proportion was 54.0%. CONCLUSION: Head-of-bed elevation improved reflux symptoms but there was no effect on quality of life. The finding of a non-optimal risk-benefit ratio warrants additional studies before this intervention can be recommended (IBELGA, ClinicalTrials.gov identifier NCT02706938).

ASSOCIATION BETWEEN INFANT NIGHTTIME-SLEEP LOCATION AND ATTACHMENT SECURITY: NO EASY VERDICT.

We tested whether mother-infant bed-sharing is associated with increased secure infant-mother attachment, a previously unexplored association. Frequency of bed-sharing and mothers' nighttime comforting measures at 2 months were assessed with questionnaires in 550 Caucasian mothers from a population-based cohort. Attachment security was assessed with the Strange Situation Procedure (M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978) at 14 months. When using a dichotomous variable, "never bed-sharing" (solitary sleepers) versus "any bed-sharing," the relative risk of being classified as insecurely attached for solitary-sleeping infants (vs. bed-sharers) was 1.21 (95% confidence interval: 1.05-1.40). In multivariate models, solitary sleeping was associated with greater odds of insecure attachment, adjusted odds ratio (OR): 1.50, 95% CI = 1.02-2.20) and, in particular, with greater odds of resistant attachment, adjusted OR = 1.74, 95% CI = 1.10-2.76); and with a lower attachment security score, ß = -0.12, t(495) = -2.61, p = .009. However, we found no evidence of a dose-response association between bed-sharing and secure attachment when using a trichotomous bed-sharing variable based on frequency of bed-sharing. Our findings demonstrate some evidence that solitary sleeping is associated with insecure attachment. However, the lack of a dose-response association suggests that further experimental study is necessary before accepting common notions that sharing a bed leads to children who are better or not better adjusted.

Evaluation of head-of-bed elevation compliance in critically ill patients under mechanical ventilation in a polyvalent intensive care unit.

OBJECTIVES: To evaluate head-of-bed elevation (HOBE) compliance in mechanically ventilated (MV) patients during different time periods, in order to identify factors that may influence compliance and to compare direct-observation compliance with checklist-reported compliance. DESIGN AND SETTING: A prospective observational study was carried out in a polyvalent Intensive Care Unit. PATIENTS: All consecutive patients with MV and no contraindication for semi-recumbency were studied. INTERVENTION AND VARIABLES: HOBE was observed during four periods of one month each for one year, the first period being blinded. HOBE was measured with an electronic device three times daily. Main variables were HOBE, type of airway device, type of bed, nursing shift, day of the week and checklist-reported compliance. No patient characteristics were collected. RESULTS: During the four periods, 2639 observations were collected. Global HOBE compliance was 24.0%, and the median angle head-of-bed elevation (M-HOBE) was 24.0° (IQR 18.8-30.0). HOBE compliance and M-HOBE by periods were as follows: blinded period: 13.8% and 21.1° (IQR 16.3-24.4); period 1: 25.5% and 24.3° (IQR 18.8-30.2); period 2: 22.7% and 24.4° (IQR 18.9-29.6); and period 3: 31.4% and 26.7° (IQR 21.3-32.6) (p<0.001). An overestimation of 50-60% was found when comparing self-reported compliance using a checklist versus direct-observation compliance (p<0.001). Multivariate logistic regression analysis found the presence of an endotracheal tube (ET) and bed without HOBE measuring device to be independently associated to greater compliance (p<0.05). CONCLUSIONS: Although compliance increased significantly during the study period, it was still not optimal. Checklist-reported compliance significantly overestimated HOBE compliance. The presence of an ET and a bed without HOBE measuring device was associated to greater compliance.

Precision medicine: "Point of Care Ultrasound" (PoCUS) in the diagnostic approach to the patient with hyponatremia.

Hyponatremia is a multifactorial disorder defined as a decrease in plasma sodium concentration. Its differential diagnosis requires an adequate evaluation of the extracellular volume (ECV). However, ECV determination, simply based on the clinical history, vital signs, physical examination, and laboratory findings can leads to misdiagnosis and inappropriate treatment. The use of Point-of-Care Ultrasound (POCUS), through the combination of Lung Ultrasound (LUS), Venous Excess UltraSound (VExUS) and Focused Cardiac Ultrasound (FoCUS), allows a much more accurate holistic assessment of the patient's ECV status in combination with the other parameters.

PsychOpen CAMA: Publication of community-augmented meta-analyses in psychology.

To enable optimal decision-making based on the best evidence available, open syntheses are called for. To make data accessible and comprehensible even for decision-makers without proficient knowledge in meta-analysis, a graphical user interface (GUI) provides flexible data visualizations including interpretation aids. Moreover, due to a growing number of research findings, efficient and easy updating of meta-analyses is crucial to prevent waste in research. One label for a concept to meet these needs is community-augmented meta-analysis (CAMA). The research community at the one hand feeds the data repository of a CAMA with new data and on the other hand benefits from easy access to data and meta-analyses on a GUI. PsychOpen CAMA has been released recently to serve the psychological research community as a whole by covering a broad scope of potential research domains. PsychOpen CAMA relies on a web application with an OpenCPU server for the R calculations. To achieve interoperability of different datasets with the analysis functions used in PsychOpen CAMA, a template for meta-analytic data and machine-readable metadata are used. In the future, the automation of workflows, flexibility of analysis options, and the scope of the platform will be further developed by making use of synergies with other resources and tools at ZPID. The article provides an overview on the rationale for the necessity of open syntheses and the CAMA approach, as well as a presentation of the architecture, user interface, functionalities and future challenges of PsychOpen CAMA.

The effect of patient transfer type to the operating room on surgical site infection: Concerns versus evidence.

BACKGROUND: Concerns about surgical site infection (SSI) give rise to practices and procedures not evidence-based. OBJECTIVES: This study investigates whether the type of patient transfer to operating rooms plays a role in developing surgical site infection. METHODS: Three thousand four hundred and seventy-one patients were divided into two groups: transfer group with stretcher (ST) (n = 1699) and patient bed transfer group (PBT) (n = 1772). The data of the two groups and the SSI rates were comparatively analyzed. RESULTS: The SSI rate was 2.5% (n = 43) in the ST group and 2.8% (n = 49) in the PBT group, and there was no statistically significant difference. Both types of patient transfer had similar effects on the probability of SSI development. The odds ratio was 1.095 for stretcher transfer while 0.913 for patient bed transfer. CONCLUSION: Patients transfer to operating rooms on their beds are comfortable and safe. Furthermore, it has a similar effect to stretcher transfer on the probability of surgical site infection. Therefore, it is safer and cheaper to act based on evidence instead of trusting our concerns.

ANTECEDENTES: las preocupaciones sobre la infección del sitio quirúrgico (ISQ) dan lugar a prácticas y procedimientos que no se basan en pruebas. OBJETIVOS: Este estudio investiga si el tipo de traslado del paciente a los quirófanos influye en el desarrollo de la infección del sitio quirúrgico. MÉTODOS: Se dividieron 3471 pacientes en dos grupos: Grupo de transferencia con camilla (ST) (n = 1699) y Grupo de transferencia de cama de paciente (PBT) (n = 1772). Los datos de los dos grupos y las tasas de ISQ se analizaron comparativamente. RESULTADOS: La tasa de ISQ fue de 2.5% (n = 43) en el grupo ST y 2.8% (n = 49) en el grupo PBT, y no hubo diferencia estadísticamente significativa. Ambos tipos de transferencia de pacientes tuvieron efectos similares sobre la probabilidad de desarrollo de ISQ. La razón de posibilidades fue de 1.095 para el traslado en camilla y de 0,913 para el traslado de la cama del paciente. CONCLUSIÓN: El traslado de los pacientes a los quirófanos en sus camas es cómodo y seguro. Además, tiene un efecto similar al traslado en camilla sobre la probabilidad de infección del sitio quirúrgico. Por lo tanto, es más seguro y económico actuar en base a evidencias en lugar de confiar en nuestras preocupaciones.

Usefulness of lung ultrasound in the diagnosis and follow-up of respiratory diseases in neonates.

OBJECTIVE: Lung ultrasound is a useful tool for diagnosis and follow-up of diseases in critically ill neonates. Its use is increasingly widespread thanks to its advantages over other imaging tests and the rapidly growing body of evidence to support it, and "point-of-care ultrasound" (POCUS) has become a key component in neonatal guidelines. The objective of this special article is to present the foundations and the established diagnostic and therapeutic applications of lung ultrasonography as well as introducing new applications. METHODS AND RESULTS: The Lung Ultrasound Section of the Neonatal Ultrasonography Working Group of the Spanish Neonatology Society has summarised the current scientific evidence. The article describes the sonographic features of the most common respiratory diseases, discusses some of the applications of ultrasound in neonatal care (such as prediction of admission and need of surfactant, ultrasound-guided procedures or monitoring of lung development in premature infants) and proposes its introduction in other scenarios in which its use is not quite established at present, such as resuscitation or respiratory management. This article reaffirms the usefulness of lung ultrasound in guiding diagnosis, clinical decision-making and prognosis and facilitating procedures. CONCLUSIONS: Lung ultrasound should be established as the gold standard for diagnosis of respiratory diseases in neonates. Therefore, training in lung ultrasound should be included in the educational curriculum of neonatologists and in diagnostic and therapeutic care protocols. Research on the subject should continue to be pursued with performance of rigorous multicentre studies to increase the quality of the evidence.

Cold bed: A challenge for an academic medical center in San Luis Potosi, Mexico.

OBJECTIVE: The objective of this study was to identify the time period during which a hospital bed could be virtually available according to the informatics and administrative hospital system while still being physically occupied by a patient in a hospital in Mexico. MATERIALS AND METHODS: A cross-sectional study was conducted in a 250-bed Academic Medical Center located in Central Northern Mexico during February 2015. Both administrative and real patient discharges were registered in a hospital format. Central tendency measures were used to present collected data and bed/day costs were obtained from official national published costs. RESULTS: Nine hundred and forty-three patients were followed up during their hospital discharge process. Overall, 2.4% of hospital beds were occupied by discharged patients. The annual cost only for cold beds was $959,220.00 US$ ($14,348,304.00 MNX), without bringing about any benefits for patients. Cold beds represented 1.31% of the 2015 annual hospital budget. CONCLUSIONS: Quality improvement initiatives must be implemented to allocate beds to patients more efficiently. The discharge process must be standardized to reduce bed/day direct hospital costs and strengthen the supervision of medical residents during this process.

OBJETIVO: Identificar el periodo de tiempo durante el cual una cama hospitalaria está virtualmente disponible en el sistema informático, mientras está ocupada por un paciente, en un hospital de México. MÉTODO: Se realizó un estudio transversal en un centro médico académico de 250 camas, localizado en el centro-norte de México, en febrero de 2015. El alta administrativa y real del paciente fueron registradas en un formato institucional. Se utilizaron medidas de tendencia central para presentar los datos. El costo del día/cama se obtuvo de lo oficial publicado para la nación. RESULTADOS: 943 pacientes fueron seguidos durante el proceso de egreso. El 2.4% del total de las camas estuvo ocupada por pacientes egresados. El costo anual por las camas frías/muertas fue de $959,220.00 US$ ($14,348,304.00 MNX), sin beneficio para los pacientes. Las camas frías/muertas representaron el 1.31% del presupuesto hospitalario anual en el año 2015. CONCLUSIONES: Es necesario implementar iniciativas de mejora para asignar eficientemente las camas a los pacientes. El proceso de egreso debe estandarizarse para reducir el costo directo hospitalario por día/cama. Hay que fortalecer la supervisión de médicos residentes que participan en este proceso.

Knockdown of CD-74 in the Proliferative and Apoptotic Activity of Breast Cancer Cells.

BACKGROUND: The cluster of differentiation (CD) 74 is known for its immunological functions and its elevated level was reported in various cancer cells. AIM: The aim of the present study was to investigate the expression and potential roles of CD74 in the proliferative and apoptotic activity of breast cancer. METHODS: Expression of CD74, macrophage migration inhibitory factor (MIF) and CD44 was assayed in CAMA-1 and MDA-MB-231 cell lines using flow cytometry. CD74 was knocked down using CD74 siRNA-transfection in CAMA-1, and MDA-MB-231 cells and proliferation and apoptosis were determined in the transfected breast cancer cells. RESULTS: The data showed that CD74, MIF and CD44 were expressed in breast cancer cell lines and were associated with cell proliferation and apoptosis. Correlation analysis revealed that CD74 was positively correlated and colocalised with MIF on the cell-surface of CAMA-1 and MDA-MB-231. The knockdown of CD74 significantly reduced CAMA-1 and MDA-MB-231 cell proliferation and increased the level of apoptotic cells. CONCLUSION: We concluded that the interactions of CD74 with MIF and CD74 with CD44 could be a potential tumour marker for breast cancer cells. Moreover, the level of co-expression of MIF and CD74 or CD44 could be a surrogate marker for the efficacy of anti-angiogenic drugs, particularly in breast cancer tumours. In short, the study revealed the potential roles of CD74 in the proliferation and apoptosis of breast cancer which may serve as a potential therapeutic target for breast cancer.

Thromboelastometry as guidance for blood management in patients undergoing cardiac surgery. / Tromboelastometría como guía de administración de hemoderivados en cirugía cardiaca.

OBJECTIVE: Thromboelastometry is a viscoelastometric method for haemostasis testing in a whole blood sample. The aim of this study was to assess the results of using thromboelastometry as guidance for blood management in cardiac surgery, postoperative adverse events and ICU stay. MATERIAL AND METHOD: Analytical and comparative non-randomised quasi-experimental prospective study with a retrospective control group. The inclusion criteria for the 80 patients were: patients undergoing cardiac surgery who had had prior cardiac surgery, endocarditis surgery or aortic arch surgery. Thirty-one patients were treated following routine transfusion practice during surgery (group A). The other 49 patients were treated with thromboelastometrically guided transfusion algorithms (group B). The main objective was blood products transfused, and postoperative adverse events and ICU stay were the secondary objectives. RESULTS: Statistical analysis showed lower transfusion rates of fresh-frozen plasma in group B compared to group A (P<.001), as well as red blood cell transfusion during surgery with an average transfusion rate of 3.9 units in group A in comparison to 2.67 units in group B (P=.125). Moreover, fibrinogen infusion was increased in group B compared to group A (P=.019). In addition, a lower rate of respiratory adverse events was found in group B (P=.019). There was a significant decrease in ICU stays over 7 days in group B compared to group A (P=.031). CONCLUSIONS: Using thromboelastometry guidance for blood management led to a meaningful reduction of fresh frozen plasma transfusion during surgery. This probably resulted in a reduction in respiratory adverse events after surgery and length of ICU stay in our patients.

Which of the branched-chain amino acids increases cerebral blood flow in hepatic encephalopathy? A double-blind randomized trial.

Branched-chain amino acids increase the brain perfusion of patients with hepatic encephalopathy (HE), but the amino acid and the mechanisms involved are still unknown. This study compared brain perfusion and clinical improvement during leucine or isoleucine supplementation. After randomization, 27 subjects with cirrhosis and HE received leucine or isoleucine supplements for one year. Brain single Photon Emission Computed Tomography (SPECT) and dynamic brain scintigraphy (DBS) were performed pretreatment and at 1, 8 and 12 months of supplementation. Brain perfusion was increased only in the isoleucine group at 8 months of treatment by both SPECT and DBS (p < 0.001 and p = 0.05, respectively) and by SPECT at the 12th month (p < 0.05). This was associated with hepatic encephalopathy improvement at 8 and 12 months (p = 0.008 and 0.004, respectively), which was not observed in the leucine group (p = 0.313 and 0.055, respectively). Isoleucine supplementation achieved a better impact on brain perfusion restoration in HE.

Targeting expression of antimicrobial peptide CAMA-Syn by adenovirus vector in macrophages inhibits the growth of intracellular bacteria.

Although purified and synthesized Cecropin A-magainin 2 (CAMA-syn) shows potent antibacterial activity in vitro, its ability to inhibit bacteria within mammal cells mediated by virus vector has not yet been investigated. To enhance its antimicrobial potential and reduce systemic side effects, it would be desirable to deliver CAMA-syn in macrophages by adenovirus vector. In this study,recombinant adenovirus Ad-MSP-CAMA/GFP were used to infect macrophages RAW264.7 cells in vitro and macrophages cells of lungs in vivo and the expression of CAMA-syn was detected by RT-PCR and observation of co-expression of GFP. Antimicrobial activity in cells was evaluated by colony enumeration. The results showed that expression of CAMA-syn in macrophages conferred antimicrobial activity against a series of bacteria, including E. coli and BCG(Bacillus Calmette-Guérin). To establish BCG infection animal model, 40 Kunming mice were randomly divided into the following four groups: adenoviral delivery of Ad-MSP-CAMA/GFP, Ad-CMV-CAMA/GFP, empty-virus Ad-GFP, and control PBS, respectively. The expression of CAMA-syn in mouse was confirmed by real-time PCR and GFP co-expression. In brief, 3 days after injection of adenoviral vector, mice were scarified, different tissues were sectioned and homogenized and colony-forming efficiency by these treated tissues was determined. The colony-forming efficiency of Ad-MSP-CAMA/GFP (78.31%) and Ad-CMV-CAMA/GFP (61.68%) showed significant reduction compared to control groups. No inhibition of bacterial colony was observed from tissues treated by the PBS or empty-virus control. In conclusion, our results demonstrated that macrophages-specific expression of antimicrobial peptide CAMA-syn in macrophages inhibited the growth of intracellular bacteria, providing a promise approach for the control of refractory intracellular infection.

Ammonia gas for bacterial control in poultry litter / Gás amônia para controle bacteriano em cama aviária

The current techniques used in the disinfection of reused poultry litter, such as lime addition, windrowing and plastic cover on the surface, do not guarantee the elimination of pathogenic microorganisms, causing damage to the environment and animal health. Gram negative bacteria, i.e., Salmonella and Escherichia coli, can be transmitted from one batch to another through reused litter, causing health damage to broilers and humans that consume food contaminated by these agents. Our study assessed the effectiveness of the methods plastic cover on the surface (PCS) and plastic cover on the surface with ammonia gas injection (PCSAI) in the control of Gram negative bacteria. The results obtained, both in laboratory conditions (Experiment 1) and in the field (Experiment 2), demonstrate that the method PCSAI with 0.22% ammonia gas had a significant reduction (P<0.05) of Gram negative bacteria in the period of 48 hours This new methodology for disinfecting poultry litter will allow its reuse in a practical and safe way, improving the preservation of the environment, of the health of broilers and consumers of poultry products.

O reaproveitamento de camas aviárias na criação de frangos de corte é uma prática muito utilizada no Brasil. Essa prática reduz custos de produção e contribui na conservação do meio ambiente. As técnicas atuais utilizadas na desinfecção de camas aviárias reaproveitadas, como adição de cal, enleiramento e lona na superfície, não garantem a eliminação de microrganismos patogênicos porque não geram quantidade suficiente de amônia. O gás amônia, em concentrações elevadas, tem efeito biocida. Bactérias Gram negativas, como as Salmonelas e Escherichia coli, podem ser transmitidas de um lote para outro através do reaproveitamento da cama, ocasionando prejuízos para a saúde das aves e dos humanos que consomem alimentos contaminados por estes agentes. Este trabalho avaliou a eficácia do método lona na superfície com injeção de gás amônia no controle de microrganismos Gram negativos. Os resultados obtidos demostraram que esse método controlou os microrganismos Gram negativos num período de 48 horas em camas de frangos de corte reaproveitadas. Assim, essa nova metodologia de desinfecção de camas de aviário permitirá sua reutilização de forma prática e segura, melhorando a saúde das aves e dos consumidores dos produtos avícolas.

Physical therapy protocols to attenuate skeletal muscle atrophy in critically ill patients: narrative review / Protocolos de terapia física para atenuar la atrofia del músculo esquelético en pacientes críticos: revisión narrativa

SUMMARY: To describe the physical therapy protocols used in critically ill patients to attenuate skeletal muscle atrophy. We conducted a search in PubMed and Embase from inception to November 2020. Observational or experimental studies published in English or Spanish that evaluated the effect of physical therapy protocols on the attenuation of skeletal muscle atrophy in critically ill patients through muscle strength or mass measurement were considered eligible. Studies were only included if they reported a detailed description of the dosing of the interventions. Seventeen studies met the eligibility criteria. We included randomised clinical trials (n = 16) and observational studies (n = 1). The total population of the included studies was 872 critically ill patients. The studies aimed to evaluate the reliability, safety or effectiveness of neuromuscular electrical stimulation (n = 10) protocols, early mobilisation (n = 3), ergometer training (n = 2), transfers in tilt table (n = 1), and blood flow restriction (n = 1). Physical therapy protocols are part of the critically ill patient's integral management. Strategies such as passive mobilisation, in-bed and out-of-bed transfers, gait training, ergometer training, and neuromuscular electrical stimulation substantially impact critically ill patients' prognoses and quality of life after hospital discharge.

RESUMEN: Describir los protocolos de terapia física usados en pacientes críticos para atenuar la atrofia muscular esquelética. Realizamos una búsqueda en PubMed y Embase desde el inicio hasta noviembre de 2020. Se consideraron los estudios observacionales o experimentales publicados en inglés o español que evaluaron el efecto de los protocolos de terapia física en la atenuación de la atrofia del músculo esquelético en pacientes críticos a través de la medición de la fuerza o la masa muscular. Los estudios solo se incluyeron si informaron una descripción detallada de la dosificación de las intervenciones. Diecisiete estudios cumplieron los criterios de elegibilidad. Se incluyeron ensayos clínicos aleatorizados (n = 16) y estudios observacionales (n = 1). La población total de los estudios incluidos fue de 872 pacientes en estado crítico. Los estudios tuvieron como objetivo evaluar la confiabilidad, seguridad o efectividad de los protocolos de estimulación eléctrica neuromuscular (n = 10), movilización temprana (n = 3), entrenamiento con ergómetro (n = 2), transferencias en mesa basculante (n = 1) y restricción del flujo sanguíneo (n = 1). Los protocolos de terapia física forman parte del manejo integral del paciente crítico. Es- trategias como la movilización pasiva, los traslados dentro y fuera de la cama, el entrenamiento de la marcha, el entrenamiento con ergómetro y la estimulación eléctrica neuromuscular tienen un impacto sustancial en el pronóstico y la calidad de vida de los pacientes críticos después del alta hospitalaria.

Aspectos históricos de la clinoterapia / Historical aspects of clinotherapy

Resumen La clinoterapia o "reposo en la cama" fue introducida como tratamiento para dolencias mentales en 1852, con el propósito de inhibir la "conciencia de movimiento" y la excitación periférica y, así, posibilitar un "reposo psíquico". En un primer momento la clinoterapia, junto con otras medidas como el open door y el non restraint, significó una alternativa a las celdas de reclusión, las camisas de fuerza y otros métodos restrictivos. Sin embargo, a la postre se vio reducida al simple aislamiento en una habitación, muchas veces en condiciones muy poco apropiadas.

Summary Clinotherapy or "bed rest" was first introduced as a treatment for mental illness in 1852, with the aim of inhibit the "consciousness of movement" and peripheral excitation, in order to make it possible a "psychological rest". At the beginning, clinotherapy, along with open door and non-restraint principles, meant an alternative to seclusion rooms, straitjackets and other restrictive practices. However, over time it became a simple seclusion in a room, many times in inappropriate conditions.
