Impact of ventilation strategies on pulmonary and cardiovascular complications in patients undergoing general anaesthesia for elective surgery: a systematic review and meta-analysis.

BACKGROUND: Many RCTs have evaluated the influence of intraoperative tidal volume (tV), PEEP, and driving pressure on the occurrence of postoperative pulmonary complications, cardiovascular complications, and mortality in adult patients. Our meta-analysis aimed to investigate the association between tV, PEEP, and driving pressure and the above-mentioned outcomes. METHODS: We conducted a systematic review and meta-analysis of RCTs from inception to May 19, 2022. The primary outcome was the incidence of postoperative pulmonary complications; the secondary outcomes were intraoperative cardiovascular complications and 30-day mortality. Primary and secondary outcomes were evaluated stratifying patients in the following groups: (1) low tV (LV, tV 6-8 ml kg-1 and PEEP ≥5 cm H2O) vs high tV (HV, tV >8 ml kg-1 and PEEP=0 cm H2O); (2) higher PEEP (HP, ≥6 cm H2O) vs lower PEEP (LP, <6 cm H2O); and (3) driving pressure-guided PEEP (DP) vs fixed PEEP (FP). RESULTS: We included 16 RCTs with a total sample size of 4993. The incidence of postoperative pulmonary complications was lower in patients treated with LV than with HV (OR=0.402, CI 0.280-0.577, P<0.001) and lower in DP than in FP group (OR=0.358, CI 0.187-0.684, P=0.002). Postoperative pulmonary complications did not differ between HP and LP groups; the incidence of intraoperative cardiovascular complications was higher in HP group (OR=1.385, CI 1.027-1.867, P=0.002). The 30-day mortality was not influenced by the ventilation strategy. CONCLUSIONS: Optimal intraoperative mechanical ventilation is unclear; however, our meta-analysis showed that low tidal volume and driving pressure-guided PEEP strategies were associated with a reduction in postoperative pulmonary complications.

Telemedicine in Cancer Pain Management: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: Telemedicine is defined as the delivery of medical services through a variety of telecommunication tools. This novel approach can fit the needs of cancer patients who cannot often reach clinics due to their disabling symptoms. In this population of patients, pain is undoubtedly the most important symptom which dramatically affects the quality of life. Our work aimed to investigate the effectiveness of telemedicine in the management of cancer pain in order to assess the feasibility of a combination between telemedicine and traditional in-person visits; we also propose a model of integration of these two approaches. METHODS: We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework to conduct our study. Quality assessment and risk of bias were performed according Cochrane criteria. Results were reported as mean differences and summarized using forest plots. We performed a trial sequential analysis (TSA) to assess the conclusiveness of our results. RESULTS: Pain severity score and pain interference were lower for patients treated with telemedicine compared to those undergoing classical management (mean difference: -0.408; P =< .001 and -0.492; P = .004, respectively). TSA confirmed that our results were statistically significant and pointed out the need of other studies to reach the required sample size. PROSPERO registration: CRD42022333260. CONCLUSIONS: Telemedicine can be effectively used to manage cancer pain. This novel approach will certainly have a revolutionary economic and organizational impact on health care systems in the next future. Furthermore, the model herein proposed could help set up an algorithm to safely and efficiently implement telemedicine.

Concomitant diagnosis of multiple sclerosis and human immunodeficiency virus (HIV) infection: case report and the review of literature.

BACKGROUND: To date, few cases of multiple sclerosis (MS) patients with concomitant Human Immunodeficiency Virus (HIV) infection have been described. However, none of the previously described cases has been treated with Natalizumab, probably due to the increasing risk of progressive multifocal leukoencephalopathy (PML). CASE: We report the case of a patient concomitantly diagnosed for HIV infection and MS treated with combined antiretroviral therapy (cART) and Natalizumab for 19 months, without clinical or radiological MS activity. CONCLUSIONS: Our case might suggest considering Natalizumab in patients with concomitant HIV infection, especially for those with significant disease activity requiring a high efficacy disease modifying treatment.

Trends for Percutaneous Tracheostomy in Italian Acute Care Setting over a 5-Year Period.

Background: Tracheostomy is a widespread procedure usually performed with a percutaneous approach for prolonged mechanical ventilation. Little is known about the population-based trends for percutaneous tracheostomies (PT). The aim of this study was to evaluate the order to analyze the characteristics, rates, and costs of PTs performed in Italy from 2009 to 2014. Methods: We analyzed 102,646 PTs performed in Italy between 2009 and 2014. We obtained the data of patients from the section of the discharge report of the Italian Ministry of Health (National Archive for Hospital Discharge Form, Ministry of Health) about age, gender, length of stay (LOS), hospital types, and hospital region for code 541 and 542 for the years 2009, 2010, 2011, 2012, 2013 and 2014. Our additional source of data was the Annual Discharge Reports of the Italian Ministry of Health. Results: In this study, including 102,646 PTs performed from 2009 to 2014, we found that (1) the rates of PTs significantly decreased over time; (2) PTs were mostly performed in patients aged less than 65 years and hospitalized in ICUs for less than 40 days; and (3) the costs of PTs severely decreased over time, with a breakpoint between 2011 and 2012. Conclusions: Percutaneous tracheostomy is still a procedure frequently performed in the setting of acute care. Although percutaneous tracheostomy still results in high medical care reimbursement, it is a safe and cost-saving procedure.

Testicular cancer and YouTube: What do you expect from a social media platform?

OBJECTIVE: To evaluate the quality information on testicular cancer uploaded on YouTube™ videos. METHODS: YouTube™ videos were searched using "Testicular cancer" as a keyword. The Patient Education Materials Assessment Tool, the Misinformation scale, and the DISCERN tool were used to assess the quality information of YouTube™ videos on testicular cancer. RESULTS: According to the selection criteria, 121 YouTube™ videos were collected for the analysis and stratified according to uploading year (2009-2014 vs 2015-2020). According to the Patient Education Materials Assessment Tool for audio-visual content, the overall Understandability score was 60% (interquartile range 45.5-75) and the overall Actionability score was 100% (interquartile range 66.7-100). According to the Misinformation scale, the lowest median was recorded for item 6 ("Effects on fertility") and the overall median Misinformation score was 2 (interquartile range 1.3-2.8). No statistically significant differences were observed according to uploading year (all P > 0.05). Of all, only 54 (44.6%) videos mentioning treatment were subsequently analyzed. Of these videos, the overall Understandability was 71.4% (interquartile range 56.3-84.6) and the overall Actionability was 100% (interquartile range 66.7-100). The overall Misinformation score was 2.8 (interquartile range 2.2-3.5). The median DISCERN score recorded for question 16 was 5 (interquartile range 3-5). CONCLUSIONS: YouTube™ is a fast and open-access source for mass information. The overall quality of the testicular cancer contents provided is sadly unsatisfactory, in the present likewise in the past. However, YouTube™ videos mentioning treatment options showed higher quality content, than the remaining one. Nevertheless, all the videos analyzed underestimated the testicular cancer effects on fertility. Nowadays, YouTube™ cannot be recommended as a reliable source of information on testicular cancer.

Brainstem involvement and respiratory failure in COVID-19.

Respiratory failure is the most worrisome problem of COVID-19. Patients may develop severe pneumonia requiring invasive mechanical ventilation and a significant proportion of them dies. It has been suggested that brainstem might play a role in severe respiratory failure of COVID-19 patients. We described three COVID-19 patients in ICU at Federico II Hospital in Naples that, although had recovered from pneumonia, could not be weaned from invasive mechanical ventilation. Our clinical evaluation was consistent with an involvement of the brainstem and especially of respiratory centre thus possibly explaining the weaning failure in patients that were awake and had recovered from lung involvement. Our data, though limited, indicate that brainstem involvement may play a role in respiratory failure and perhaps in the high death rate of COVID-19 patients. Moreover, the weaning failure from mechanical ventilation due to central respiratory drive depression might underlie the unusual long stay in ICU reported for COVID-19 patients.

Obstetric Admissions in ICU in a Tertiary Care Center: A 5-Years Retrospective Study.

BACKGROUND AND AIM: Obstetric patients admitted to intensive care unit (ICU) represent a challenge to physicians. The purpose of this study is to evaluate the incidence, characteristics, and mortality of pregnant and postpartum patients requiring ICU admission. MATERIALS AND METHODS: A retrospective cohort study was performed between January 2008 and December 2013 at the University Hospital Federico II of Naples including pregnant and puerperal women until the 42nd day of postpartum and admitted to ICU. RESULTS: Patients admitted with an obstetric diagnosis had a higher incidence of at least one previous cesarean section, were treated more with hysterectomy, had an increasing incidence of hemodynamic instability, had more postpartum admission, had a higher TISS-28 score, and required more endotracheal intubation than patients admitted with non-obstetrics diagnosis. CONCLUSION: A shared approach including a close collaboration between ICU and obstetric ward may be useful to reduce ICU admission and to improve maternal and foetal outcomes.

Comparison between surgical and percutaneous tracheostomy effects on procalcitonin kinetics in critically ill patients.

Available evidence from randomized controlled trials including adult critically ill patients tends to show that percutaneous dilatational tracheostomy (PDT) techniques are performed faster and reduce stoma inflammation and infection but are associated with increased technical difficulties compared with surgical tracheostomy (ST). A recent meta-analysis found that PDT was superior to reduce risk of periprocedural stoma inflammation and infection compared with ST. WE found no differences in procalcitonin, C-reactive protein, SOFA, and SAPS II between critically ill patients with ST or PDT.

Pregnant Patients with COVID-19 Admitted to an ICU: A Comparison with a Historical Cohort of Critical Pregnant Patients without COVID-19.

AIM OF THE STUDY: Maternal mortality and ICU admissions have increased during the COVID-19 pandemic. We reported a case-series of pregnant patients with COVID-19 admitted to an ICU and we compared them with a historical cohort of pregnant patients admitted to an ICU without COVID-19. METHODS: We included all pregnant patients with laboratory-confirmed COVID-19 infection admitted to our ICU in 2021. As a historical control group, we included all pregnant women who were admitted to our ICU between 1 January 2008 and 31 December 2013. RESULTS: In 2021, 11 pregnant patients (pts) with COVID-19 were admitted to an ICU, representing 2.87% of ICU admissions. We found that pregnant patients with COVID-19 (1) had a higher BMI (34.6 vs. 28.8, p = 0.04) and a lower gestational age (30.6 vs. 34 weeks, p = 0.03), (2) were mainly admitted for respiratory failure (100% vs. 2.7%; p = 0.001) and (3) required more days of invasive and non-invasive ventilations (54.5% vs. 5.2%, p = 0.002), a longer duration of stay at the ICU (21.9 vs. 4.8 days, p < 0.0001) and had a higher mortality rate (27.3% vs. 0%, p = 0.0192). CONCLUSIONS: Pregnant patients with COVID-19 represent a challenge for ICU physicians due to their different characteristics and outcomes when compared to pregnant patients without COVID-19.

Videolaryngoscopy versus Fiberoptic Bronchoscopy for Awake Tracheal Intubation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: In recent years, videolaryngoscopy has increasingly been utilized as an alternative to fiberoptic bronchoscopy in awake intubation. Nonetheless, it remains uncertain whether videolaryngoscopy represents a viable substitute for fiberoptic bronchoscopy. We conducted this systematic review with a meta-analysis to compare videolaryngoscopy and fiberoptic bronchoscopy for awake intubation. Methods: We systematically searched for all randomized controlled trials (RCTs) comparing videolaryngoscopy and fiberoptic bronchoscopy for awake intubation. The Cochrane Central Register of Controlled Trials (CENTRAL), Embase, and MEDLINE were systematically queried through August 2023. Our primary outcome measure was the duration of intubation. Secondary outcomes encompassed the rate of successful intubation on the initial attempt, failed intubation, patient-reported satisfaction, and any complications or adverse events potentially stemming from the intubation procedure. The Cochrane Risk of Bias Tool for RCTs was employed to evaluate all studies for evidence of bias. The GRADE approach was utilized to gauge the certainty of the evidence. Results: Eleven trials involving 873 patients were ultimately included in our review for data extraction. Meta-analysis demonstrated that videolaryngoscopy decreased the duration of intubation compared to fiberoptic bronchoscopy (SMD -1.9671 [95% CI: -2.7794 to -1.1548] p < 0.0001), a finding corroborated in subgroup analysis by the type of videolaryngoscope (SMD -2.5027 [95% CI: -4.8733 to -0.1322] p = 0.0385). Additionally, videolaryngoscopy marginally lowered the risk of experiencing a saturation below 90% during the procedure (RR -0.7040 [95% CI: -1.4038 to -0.0043] p = 0.0486). No statistically significant disparities were observed between the two techniques in terms of failed intubation, initial successful intubation attempt, or sore throat/hoarseness. With regard to patient-reported satisfaction, a pooled analysis was precluded due to the variability in evaluation methods employed across the trials to assess this outcome. Lastly, trial sequential analysis (TSA) conducted for intubation time (primary outcome) affirmed the conclusiveness of this evidence; TSA performed for secondary outcomes failed to yield conclusive evidence, indicating the necessity for further trials. Conclusions: Videolaryngoscopy for awake tracheal intubation diminishes intubation time and the risk of experiencing a saturation below 90% compared to fiberoptic bronchoscopy.

The Effects of the Pericapsular Nerve Group Block on Postoperative Pain in Patients with Hip Fracture: A Multicenter Study.

BACKGROUND: An adequate early mobilization followed by an effective and pain-free rehabilitation are critical for clinical and functional recovery after hip and proximal femur fracture. A multimodal approach is always recommended so as to reduce the administered dose of analgesics, drug interactions, and possible side effects. Peripheral nerve blocks should always be considered in addition to spinal or general anesthesia to prolong postoperative analgesia. The pericapsular nerve group (PENG) block appears to be a less invasive and more effective analgesia technique compared to other methods. METHODS: We conducted multicenter retrospective clinical research, including 98 patients with proximal femur fracture undergoing osteosynthesis surgery within 48 h of occurrence of the fracture. Thirty minutes before performing spinal anesthesia, 49 patients underwent a femoral nerve (FN) block plus a lateral femoral cutaneous nerve (LCFN) block, and the other 49 patients received a PENG block. A non-parametric Wilcoxon-Mann-Whitney (α = 0.05) test was performed to evaluate the difference in resting and dynamic numerical rating scale (NRS) at 30 min, 6 h, 12 h, and 24 h. RESULTS: the PENG block administration was more effective in reducing pain intensity compared to the FN block in association with the LFCN block, as seen in the resting and dynamic NRS at thirty minutes and 12 h follow-up. CONCLUSION: the PENG block was more effective in reducing pain intensity than the femoral nerve block associated with the lateral femoral cutaneous nerve block in patients with proximal femur fracture undergoing to osteosynthesis.

Potential Role of Focal Microvibration (Equistasi®) in the Management of Chronic Pain: A Pilot Study.

INTRODUCTION: Chronic pain is one of the leading causes of medical consultation with a dramatic psychophysical and socioeconomic impact. Focal microvibration (Equistasi®) is a revolutionary technology that converts the thermal energy of the skin into vibration. Equistasi® was shown to be effective in the treatment of gait and balance dysfunction in many pathological conditions such as Parkinson's disease and multiple sclerosis. Our aim was to explore the efficacy of focal microvibration in the management of chronic pain. METHODS: We randomized 60 patients with pain of different origin into two groups: an experimental group (group E) treated with Equistasi, and a control group (group C) treated with standard pharmacological therapy. Pain, disability, and working capacity were evaluated by Brief Pain Inventory (BPI), Oswestry Disability Index (ODI), and Work Ability Index (WAI) at the baseline and after 7 (T7), 15 (T15), 30 (T30), 60 (T60), and 90 (T90) days. RESULTS: According to BPI, average and worst pain in the last 24 h significantly decreased in group E at T15 and this result persisted up to T90; pain interference on general activity, mood, waling ability, normal work, relations with other people, sleep, and enjoyment of life decreased in group E with a significant improvement from T15. Lifting activity and work ability in relation to demands also significantly improved in group E. No significant changes in BPI, ODI, and WAI scores were recorded in group C during the follow-up. CONCLUSIONS: Focal microvibration can be an effective tool for managing chronic pain in combination with other therapies.
