Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia)

Epidemiology, practice of ventilation and outcome for patients at increased risk of postoperative pulmonary complications

BACKGROUND Limited information exists about the epidemiology and outcome of surgical patients at increased risk of postoperative pulmonary complications (PPCs), and how intraoperative ventilation was managed in these patients. OBJECTIVES To determine the incidence of surgical patients at increased risk of PPCs, and to compare the intraoperative ventilation management and postoperative outcomes with patients at low risk of PPCs. DESIGN This was a prospective international 1-week observational study using the ‘Assess Respiratory Risk in Surgical Patients in Catalonia risk score’ (ARISCAT score) for PPC for risk stratification. PATIENTS AND SETTING Adult patients requiring intraoperative ventilation during general anaesthesia for surgery in 146 hospitals across 29 countries. MAIN OUTCOME MEASURES The primary outcome was the incidence of patients at increased risk of PPCs based on the ARISCAT score. Secondary outcomes included intraoperative ventilatory management and clinical outcomes. RESULTS A total of 9864 patients fulfilled the inclusion criteria. The incidence of patients at increased risk was 28.4%. The most frequently chosen tidal volume (VT) size was 500 ml, or 7 to 9 ml kg1 predicted body weight, slightly lower in patients at increased risk of PPCs. Levels of positive end-expiratory pressure (PEEP) were slightly higher in patients at increased risk of PPCs, with 14.3% receiving more than 5 cmH2O PEEP compared with 7.6% in patients at low risk of PPCs (P < 0.001). Patients with a predicted preoperative increased risk of PPCs developed PPCs more frequently: 19 versus 7%, relative risk (RR) 3.16 (95% confidence interval 2.76 to 3.61), P < 0.001) and had longer hospital stays. The only ventilatory factor associated with the occurrence of PPCs was the peak pressure. CONCLUSION The incidence of patients with a predicted increased risk of PPCs is high. A large proportion of patients receive high VT and low PEEP levels. PPCs occur frequently in patients at increased risk, with worse clinical outcome

The burden of disease in Greece, health loss, risk factors, and health financing, 2000–16:an analysis of the Global Burden of Disease Study 2016

Background: Following the economic crisis in Greece in 2010, the country's ongoing austerity measures include a substantial contraction of health-care expenditure, with reports of subsequent negative health consequences. A comprehensive evaluation of mortality and morbidity is required to understand the current challenges of public health in Greece. Methods: We used the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 to describe the patterns of death and disability among those living in Greece from 2000 to 2010 (pre-austerity) and 2010 to 2016 (post-austerity), and compared trends in health outcomes and health expenditure to those in Cyprus and western Europe. We estimated all-cause mortality from vital registration data, and we calculated cause-specific deaths and years of life lost. Age-standardised mortality rates were compared using the annualised rate of change (ARC). Mortality risk factors were assessed using a comparative risk assessment framework for 84 risk factors and clusters to calculative summary exposure values and population attributable fraction statistics. We assessed the association between trends in total, government, out-of-pocket, and prepaid public health expenditure and all-cause mortality with a segmented correlation analysis

Anesthetic management of mosaic Turner&apos;s syndrome posted for elective cesarean delivery after spontaneous pregnancy

Turner&apos;s syndrome, one of the most common sex chromosome abnormalities in females, is caused by loss of part or all of an X chromosome. We report a case of mosaic Turner&apos;s syndrome, posted for elective cesarean delivery under low-dose sequential combined spinal-epidural anesthesia. The unique features of this case were the combination of an anticipated difficult airway and both short stature and scoliosis in the lumbar region. A titrated combined spinal-epidural technique was performed in order to avoid hemodynamic instability, which could have been exacerbated in the presence of cardiovascular deformities that accompany this syndrome in many cases. The patient was managed successfully under regional anesthesia, which is generally a preferred technique to general anesthesia, to avoid sympathetic stimulation during intubation and emergence. Further, this technique may avoid potential complications associated with difficult airway management. © 2017 Elsevier Lt

Role of critical care units in the management of obstetric patients (Review)

Pregnancy is considered a natural process for the majority of women. However, a limited proportion of pregnancies and deliveries can present with a broad variety of complications that may require admission to a Critical Care Unit (CCU). In the present review, the indications of admission of obstetrical and postpartum patients to CCUs were critically evaluated with a particular focus on the management of their complications. The management of critically ill obstetric patients remains challenging due to the physiological changes that occur during pregnancy, pregnancy-related diseases and the need to carefully consider the well-being of the fetus before any intervention can be recom-mended/performed. Indications for admission to CCUs include both obstetric and non-obstetric conditions that may require continuous monitoring and further interventions. Hypertensive disorders of pregnancy and mass hemorrhage are amongst the most common causes of admission to CCUs in pregnant and postpartum women. The establishment of a diagnostic and care algorithm based on the contribution of a multidisciplinary team is of critical importance to aid in the determination of which patients will require intensive care, and to assist in deciding what type of critical care each critically ill patients receives. © 2021, Spandidos Publications.

Pencil-point needle bevel direction influences ED50 of isobaric ropivacaine with fentanyl in spinal anesthesia for cesarean delivery: A prospective, double-blind sequential allocation study

Background: There is little evidence on the influence of bevel direction of a pencil-point needle on the median effective dose (ED50) of isobaric ropivacaine and fentanyl in spinal anesthesia for cesarean delivery. Methods: In this prospective, double-blind, sequential allocation study, 82 parturients scheduled for elective cesarean delivery under combined spinal-epidural anesthesia were included. We sought to determine the median effective dose of intrathecal 0.75% isobaric ropivacaine plus fentanyl 15 lg with two different bevel directions of a 26-gauge Whitacre needle using up-down sequential allocation. Parturients were randomly allocated to either Group Ce (needle aperture oriented in a cephalad direction) or Group Ca (aperture directed caudally). The initial dose was 0.75% ropivacaine 11.25 mg plus fentanyl 15 lg in both groups. Each dose was classified as effective if, after 15 min and during the next 60 min, there was inability to appreciate pin-prick as sharp at T4, a visual analogue pain score &lt;2 and no requirement for an epidural rescue bolus. Results: Eighty patients were included in the analysis. The ED50 in group Ca was significantly higher (13.09 mg, 95% CI 12.19-14.00) than in group Ce (10.10 mg, 95% CI 9.54-10.65, P &lt;0.001). Conclusion: The orientation of the distal aperture of a 26-gauge Whitacre needle during induction of spinal anesthesia for cesarean delivery influences the ED50 of 0.75% ropivacaine.

Local analgesic effect of pethidine infiltrated intrafascially after total abdominal hysterectomy: A randomized, double-blind study

Objective: Surgical-site infiltration with local anesthetics is a key component of multimodal analgesia regimen for adequate postoperative pain management. This randomized, double-blind study was designed to evaluate the local analgesic efficacy of pethidine in patients undergoing total abdominal hysterectomy (TAH) through a Pfannenstiel incision. Materials and Methods: Patients were randomized into two groups. The first group received wound infiltration (WI) with 0.5 mg/kg pethidine, diluted in 15 ml normal saline, and injected in the fascial layer at the end of surgery, combined with a simultaneous intramuscular (IM) injection of 2.5 ml normal saline (WI group). The second group received WI with 15 ml normal saline combined with an IM injection of 0.5 mg/kg pethidine and diluted in 2.5 ml normal saline (IM group). All patients received general anesthesia following a standardized anesthetic protocol. Study end points were 24-h total morphine consumption and pain scores based on a visual analog scale (VAS) at rest and on coughing at 1, 3, 6, and 24 postoperative h, as well as sedation scores observed using a 0-10 numeric rating scale. Adverse effects from morphine uptake, such as nausea, vomiting, and the need for rescue antiemetics, were recorded as well. Results: Postoperative VAS assessments showed no statistically significant advantage between WI and IM method, while the total (24h) consumption of morphine was lower in the IM, compared to the WI group (27.2%). The latter demonstrated a consistently higher median sedation score at all assessed time points after the operation (P &lt; 0.05); however, it was significantly different only at the 6 h time point. Conclusions: Local WI with pethidine after TAH did not reduce the total morphine consumption for the first 24 h postoperatively. Morphine consumption was lower in the IM group, compared to the WI group. Further studies are needed to assess the effectiveness of pethidine as a local anesthetic agent. © 2018 Journal of Natural Science, Biology and Medicine | Published by Wolters Kluwer - Medknow

Deep neuromuscular blockade in gynecological laparoscopic surgery: A review

Minimally invasive surgery has achieved remarkable progress during the last three decades in the field of operative gynecology. The intrinsic advantages of laparoscopy i.e. shorter operative time, less abdominal trauma, faster recovery and shorter hospitalization, combined with new advances in instrumentation, energy sources, and operative techniques, contributed to this shift towards laparoscopy for the operative management of a variety of gynecological conditions. One of the most important prerequisites for an effective and complications- free laparoscopic operation is the need to constantly maintain a good operative field. Concomitant advances in the area of anesthesia, like the use of objective neuromuscular monitoring and the introduction of new reversal agents have allowed clinicians to apply deep neuromuscular blockade (NMB) during laparoscopic operations with markedly reduced postoperative residual curarization. This evolution appears to contribute significantly to the establishment of a good operative field, especially during advanced and lengthy laparoscopic procedures, maintaining optimal conditions even when low-pressure laparoscopy (eight mmHg) is performed. The aim of this review is to present the principles of deep NMB and examine the possible benefits of its use during laparoscopy
