Review
It is well known by surgeons that patient positioning is fundamental to exposing the organs when performing an operation via laparoscopy, as gravity can help move the organs and facilitate the exposure of the surgical site. But is it also important for endoscopic procedures? This paper examines various types of endoscopic operations and addresses the issue of the patient's position. The patient's position can be changed not only by rotating the patient along the head-toe axis but also by tilting the surgical bed, as is undertaken during laparoscopic surgical procedures. In particular, it is useful to take into account the effect of gravity on lesion exposure, tumour traction during dissection, crushing by body weight, risk of sample drop, risk of damage to adjacent organs, and anatomical exposure for procedures with radiological support. The endoscopist should always keep in mind the patient's anatomy and the position of the endoscope during operative procedures, not limited to considering only intraluminal vision.

Review
OBJECTIVE
The incidence of skin/tissue damage, such as pressure ulcers, remains high in mechanically ventilated patients in the prone position. According to guidelines, critically ill patients with acute respiratory distress syndrome (ARDS) should be prone for at least 12-16 hours to improve oxygenation and decrease mortality. Therefore, educating clinicians on how to reposition and manage the patient safely in a prone position plays a vital role in preventing adverse events. This project aimed to develop accessible online educational content to assist clinicians in safely executing the prone manoeuvre and minimise skin/tissue damage.
METHOD
The development of the educational content was based on: a gap analysis and comprehensive review of available educational resources; evidence-based scientific literature; advice from international experts; and a qualitative study exploring the learning needs of 20 clinicians in Belgium and Sweden between February-August 2022.
RESULTS
Volunteer clinicians assisted with the creation of eight simulation videos which were professionally filmed and edited. The interactive videos included the supine-to-prone and prone-to-supine manoeuvres, endotracheal and nasogastric tube securement, eye care, stoma care, protecting high-risk areas from pressure damage, and incontinence-associated dermatitis prevention. A prone positioning protocol, a checklist summarising the key aspects of the protocol, and teaching aids (slide deck for didactic lecturing) were developed and validated by a review of the relevant evidence-based literature and the international expert panel. A website was designed to host the content, with free user access, at www.pronetection.com.
CONCLUSION
Education is one strategy towards prevention of complications of prone positioning. Accessible education could assist clinicians unfamiliar with prone positioning or current clinicians requiring refresher training to safely manage patients in this position.

Standard minimally invasive Ivor Lewis oesophagectomy is performed through a multiport technique using carbon dioxide. However, access to video-assisted thoracoscopic surgery (VATS) is increasingly shifting to a single-port approach due to its proven safety and efficacy in lung surgeries. Therefore, the preamble of this submission is to describe, 'How I do differently' uniportal VATS MIO in three major steps: (a) VATS dissection through a single 4-cm incision in a semi-prone position without artificial capnothorax; (b) fluorescence dye to check conduit perfusion and (c) intrathoracic overlay anastomosis with a linear stapler.

Review
Comprehensive ultrasound assessment has become an essential tool to facilitate the diagnosis and therapeutic management of critically ill patients with acute respiratory failure (ARF). There is evidence supporting the use of ultrasound for the diagnosis of pneumothorax, acute respiratory distress syndrome, cardiogenic pulmonary edema, pneumonia and acute pulmonary thromboembolism, and in patients with COVID-19. In addition, in recent years, the use of ultrasound to evaluate responses to treatment in critically ill patients with ARF has been developed, providing a noninvasive tool for titrating positive end-expiratory pressure, monitoring recruitment maneuvers and response to prone position, as well as for facilitating weaning from mechanical ventilation. The objective of this review is to summarize the basic concepts on the utility of ultrasound in the diagnosis and monitoring of critically ill patients with ARF.

Air Medical Journal 2023This is a retrospective quality review of LifeFlight Nova Scotia's prone patient transport protocol.
OBJECTIVE
This is a retrospective quality review of LifeFlight Nova Scotia's prone patient transport protocol.
METHODS
Electronic patient care records were queried for acute respiratory distress syndrome, prone position, proning, supine to prone, and prone to prone between February 2017 and June 2022. Eligible electronic patient care records were reviewed for demographics (sex, age, and weight); method of transports (ambulance, rotor wing, or fixed wing); duration of transports; mechanical ventilation parameters; medication infusions; arterial blood gases; occurrences of mild hypoxemia (any oxygen saturation [SpO] < 88% or decrease in SpO > 5%); hypotension (any episode of MAP < 65 mm Hg); severe hypoxemia (any SpO < 80% or decrease in SpO > 10%); refractory hypotension (mean arterial pressure < 65 mm Hg not responsive to vasopressor/inotropes); cardiac arrests; and displacement of central lines, arterial lines, and endotracheal tubes.
RESULTS
Seventeen prone patients were transported by ambulance, rotor wing, and fixed wing with 4 occurrences of mild hypotension, 4 occurrences of mild hypoxemia, and 1 occurrence of refractory hypotension.
CONCLUSION
Interfacility transfer of prone patients by a dedicated critical care team is feasible with minimal adverse occurrences while ensuring patients have access to the specialized lifesaving care they require.

Review
BACKGROUND
Lumbar puncture is a common invasive procedure performed in newborns for diagnostic and therapeutic purposes. Approximately one in two lumbar punctures fail, resulting in both short- and long-term negative consequences for the clinical management of patients. The most common positions used to perform lumbar puncture are the lateral decubitus and sitting position, and each can impact the success rate and safety of the procedure. However, it is uncertain which position best improves patient outcomes.
OBJECTIVES
To assess the benefits and harms of the lateral decubitus, sitting, and prone positions for lumbar puncture in newborn infants.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was 24 January 2023.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) and quasi-RCTs involving newborn infants of postmenstrual age up to 46 weeks and 0 days, undergoing lumbar puncture for any indication, comparing different positions (i.e. lateral decubitus, sitting, and prone position) during the procedure.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. We used the fixed-effect model with risk ratio (RR) and risk difference (RD) for dichotomous data and mean difference (MD) and standardized mean difference (SMD) for continuous data, with their 95% confidence intervals (CI). Our primary outcomes were successful lumbar puncture procedure at the first attempt; total number of lumbar puncture attempts; and episodes of bradycardia. We used GRADE to assess the certainty of evidence for each outcome.
MAIN RESULTS
We included five studies with 1476 participants. Compared to sitting position: lateral decubitus position probably results in little to no difference in successful lumbar puncture procedure at the first attempt (RR 0.99, 95% CI 0.88 to 1.12; RD 0.00, 95% CI -0.06 to 0.05; I = 47% and 46% for RR and RD, respectively; 2 studies, 1249 infants, low-certainty evidence). None of the studies reported the total number of lumbar puncture attempts as specified in this review. Lateral decubitus position likely increases episodes of bradycardia (RR 1.72, 95% CI 1.08 to 2.76; RD 0.03, 95% CI 0.00 to 0.05; number needed to treat for an additional harmful outcome (NNTH) = 33; I = not applicable and 69% for RR and RD, respectively; 3 studies, 1279 infants, moderate-certainty evidence) and oxygen desaturation (RR 2.10, 95% CI 1.42 to 3.08; RD 0.06, 95% CI 0.03 to 0.09; NNTH = 17; I = not applicable and 96% for RR and RD, respectively; 2 studies, 1249 infants, moderate-certainty evidence). Lateral decubitus position results in little to no difference in time to perform the lumbar puncture compared to sitting position (I = not applicable; 2 studies; 1102 infants; high-certainty evidence; in one of the study median and IQR to report time to perform the lumbar puncture were 8 (5-13) and 8 (5-12) in the lateral and sitting position, respectively, I = not applicable; 1 study, 1082 infants; in the other study: mean difference 2.00, 95% CI -4.98 to 8.98; I = not applicable; 1 study, 20 infants). Lateral decubitus position may result in little to no difference in the number of episodes of apnea during the procedure (RR not estimable; RD 0.00, 95% CI -0.03 to 0.03; I = not applicable and 0% for RR and RD, respectively; 2 studies, 197 infants, low-certainty evidence). No studies reported apnea defined as number of infants with one or more episodes during the procedure. Compared to prone position: lateral decubitus position may reduce successful lumbar puncture procedure at first attempt (RR 0.75, 95% CI 0.63 to 0.90; RD -0.21, 95% CI -0.34 to -0.09; number needed to treat for an additional beneficial outcome = 5; I = not applicable; 1 study, 171 infants, low-certainty evidence). None of the studies reported the total number of lumbar puncture attempts or episodes of apnea. Pain intensity during and after the procedure was reported using a non-validated pain scale. None of the studies comparing lateral decubitus versus prone position reported the other critical outcomes of this review.
AUTHORS' CONCLUSIONS
When compared to sitting position, lateral decubitus position probably results in little to no difference in successful lumbar puncture procedure at first attempt. None of the included studies reported the total number of lumbar puncture attempts as specified in this review. Furthermore, infants in a sitting position likely experience less episodes of bradycardia and oxygen desaturation than in the lateral decubitus, and there may be little to no difference in episodes of apnea. Lateral decubitus position results in little to no difference in time to perform the lumbar puncture compared to sitting position. Pain intensity during and after the procedure was reported using a pain scale that was not included in our prespecified tools for pain assessment due to its high risk of bias. Most study participants were term newborns, thereby limiting the applicability of these results to preterm babies. When compared to prone position, lateral decubitus position may reduce successful lumbar puncture procedure at first attempt. Only one study reported on this comparison and did not evaluate adverse effects. Further research exploring harms and benefits and the effect on patients' pain experience of different positions during lumbar puncture using validated pain scoring tool may increase the level of confidence in our conclusions.

International Journal of Urology :... Dec 2023To identify atypical masturbatory behaviors (AMB) and to reveal their effects on both sexual and masturbational erection hardness in men with erectile dysfunction (ED).
OBJECTIVE
To identify atypical masturbatory behaviors (AMB) and to reveal their effects on both sexual and masturbational erection hardness in men with erectile dysfunction (ED).
METHODS
Patients with ED and healthy controls were questioned about their masturbation habits. Accordingly, "rubbing in a prone position," "pressure on penis," and "masturbation through clothes" were included in the traumatic masturbation syndrome (TMS) group. Erection hardness score (EHS) is used to measure the erectile functions during masturbation (mast), foreplay (presex), and sexual intercourse (sex), separately.
RESULTS
The data of 448 participants, 266 (59%) from the patient group, and 182 (41%) from the control group were analyzed. The mean ages were 30 years in both groups (p = 0.734). The rate of "rubbing in a prone position" and "penile pressure" while masturbating was higher in patients than the controls (10.2% vs. 6%, p = 0.024 and 8.6% vs. 3.3%, p = 0.0002, respectively). Patients had 2.2-fold (odds ratio, 2.21; 95% confidence interval, 1.40-3.47; p = 0.001) increased risks of having at least one AMB, compared with controls. In the secondary analysis, the patient group was divided into 2 subgroups according to having TMS (ED + TMS) or not (ED). The percentage of patients with EHS≥3 during masturbation was higher than those during sex and presex in the "ED + TMS" group (60.2%, 38.8%, and 37.2%, respectively, p = 0.0001; n = 98). Comparing the percentage of patients with EHS≥3 during mast, presex, and, sex was found to be similar in the "ED" group (58.9%, 56.5%, and 56%, respectively, p = 0.753; n = 168).
CONCLUSION
Atypical masturbatory behaviors are more common in young men presenting with erectile dysfunction. These patients have higher erection hardness scores during masturbation compared to partnered sex.

PURPOSE
To probe the differences of dosimetry and acute radiation enteritis between prone and supine position in gynecological cancer patients treated with intensity-modulate radiotherapy (IMRT).
METHODS
Gynecologic tumor patients who received IMRT from January 2020 to July 2021 were analyzed. 60 patients were enrolled and divided into the supine or prone position group according to different radiotherapy positions, including 34 patients in prone position and 26 patients in supine position. The dose-volume histogram of organs at risk (OARs) and the incidence of acute radiation enteritis were compared between the two groups. Multivariate logistic regression analysis was conducted to show the clinical characteristics and dose volume metrics to the association of acute radiation enteritis.
RESULTS
The percentage of volume receiving 5 Gy, 10 Gy, 15 Gy, 20 Gy, 30 Gy, 40 Gy, and 45 Gy doses for the small intestine were 79.0%, 67.4%, 59.6%, 44.3%, 17.0%, 8.9%, and 6.0%, respectively in the prone group, which were lower than those in the supine group (P < 0.05). The mean radiation dose (D ) of the small intestine exposure in prone group was decreased (P < 0.001). Compared with the supine group, the prone group who suffered from acute radiation enteritis were much less. The probability of indigestion, nausea, vomiting, diarrhea, and abdominal pain in the prone position were 35.29%, 29.41%, 17.65%, 38.24%, and 5.88%, respectively. The differences in indigestion, nausea, and diarrhea between the two groups were statistically significant (P = 0.012, P = 0.029, and P = 0.041). Multivariate logistic regression analysis was shown that prone position was found to be protective against indigestion (P = 0.002), nausea (P = 0.013), vomiting (P = 0.035), and abdominal pain (P = 0.021).
CONCLUSION
Prone position in IMRT for gynecological cancers could significantly reduce radiation dose to the small bowel and colon, which would decrease the occurrence and severity of acute intestinal side effects possibly.

Review
COVID-19 pneumonia presents several particularities in its clinical presentation (cytokine storm, silent hypoxemia, thrombo-embolic risk) and may lead to a number of acute respiratory distress syndrome (ARDS) phenotypes. While the optimal oxygenation strategy in cases of hypoxemic acute respiratory failure (ARF) is still under debate, ventilatory management of COVID-19-related ARF has confirmed the efficacy of high-flow oxygen therapy and restored interest in other ventilatory approaches such as continuous positive airway pressure (CPAP) and noninvasive ventilation involving a helmet, which due to patient overflow are sometimes implemented outside of critical care units. However, further studies are still needed to determine which patients should be given which oxygenation technique, and under which conditions they require invasive mechanical ventilation, given that delayed initiation potentially burdens prognosis. During invasive mechanical ventilation, ventral decubitus and extracorporeal membrane oxygenation have become increasingly prevalent. While innovative therapies such as awake prone position or lung transplantation have likewise been developed, their indications, modalities and efficacy remain to be determined.
