Remimazolam has been suggested to improve the maintenance of hemodynamic stability when compared with other agents used for general anesthesia. This study aimed to compare the effects of remimazolam and sevoflurane anesthesia on hemodynamic stability in patients undergoing robotic gastrectomy. We retrospectively reviewed the electronic medical records of 199 patients who underwent robotic gastrectomy with sevoflurane (n = 135) or remimazolam (n = 64) anesthesia from January to November 2021. Propensity scores were used for 11 matching between the groups. The primary outcome was the difference in use of intraoperative vasopressors between groups. Secondary outcomes included differences in incidence and dose of vasopressors, as well as intraoperative hemodynamic variables, between groups. Remimazolam anesthesia was associated with a significantly less frequent use of ephedrine (odds ratio (OR) 0.13; 95% confidence interval (CI) 0.05-0.38, p < 0.001), phenylephrine (OR 0.12; 95% CI 0.04-0.40, p < 0.001), and any vasopressor (OR 0.06; 95% CI 0.02-0.25, p < 0.001) compared with sevoflurane anesthesia. Remimazolam anesthesia enables better maintenance of hemodynamic stability than sevoflurane anesthesia. Thus, remimazolam anesthesia may be beneficial for patients who are expected to experience hypotension due to the combined effects of CO2 pneumoperitoneum and the head-up position utilized during robotic gastrectomy.Inhaled nitric oxide (iNO) remains one of the treatment modalities in shock, and in addition to its vasoactive properties, iNO exerts immunomodulatory effects. We used a porcine model of endotoxemia with shock resuscitation (control) and additional treatment with iNO and a steroid (treatment group). After 20 h, bone marrow (BM), peripheral blood (PB), and bronchoalveolar lavage fluid (BALF) were collected to analyze the immunophenotype and mitochondrial membrane potential (Δφ) in three subsets of monocytes. In both groups, SLA-DR expression decreased twofold on the circulating CD14+CD163+ and CD14-CD163+ monocytes, while it did not change on the CD14+CD163+. Δφ increased only in the CD14-CD163+ subpopulation (0.8 vs. 2.0, p < 0.001). The analysis of compartment-specific alterations showed that nearly 100% of BALF CD14+CD163+ and CD14-CD163+ monocytes expressed SLA-DR, and it was higher compared to PB (32% and 20%, p < 0.0001) and BM (93% and 67%, p < 0.001, respectively) counterparts. BALF CD14+CD163+ had a threefold higher Δφ than PB and BM monocytes, while the Δφ of the other subsets was highest in PB monocytes. We confirmed the compartmentalization of the monocyte response during endotoxemic shock, which highlights the importance of studying tissue-resident cells in addition to their circulating counterparts. The iNO/steroid treatment did not further impair monocyte fitness.In this article, the effects of cross-section and pitch on the mechanical response of NiTi endodontic files is studied by means of finite element analyses. The study was conducted over a set of eight endodontic rotary files, whose geometry was obtained from combinations of two cross-sections (square and triangular) and four pitches. Each file was subjected to bending and torsional analyses, simulating the testing conditions indicated in the ISO 3630 Standard, in order to assess their stiffness and mechanical strength. The results indicate that endodontic files with a square cross-section have double the stiffness of those with triangular cross-sections, both in terms of bending and torsion. For both loading modes, endodontic files with a triangular cross-section can undergo larger deformations before overload failure than those with a square cross-section up to 20% more in bending and 40% in torsion. Moreover, under equivalent boundary conditions, endodontic files with triangular cross-sections present a higher fatigue life than those with square cross-sections up to more than 300% higher for small pitches. The effect of pitch on the stiffness and strength of the file is smaller than that of the cross-section shape, but smaller pitches could be beneficial when using a triangular cross-section, as they increase the bending flexibility, fatigue life, and torsion stiffness. These results suggest a clinical recommendation for the use of files with a triangular-shaped cross-section and a small pitch in order to minimize ledging and maximize fatigue life. Finally, in this study, we reveal the sensitivity of the orientation of files with respect to the bending direction, which must be taken into account when designing, reporting, and interpreting test results under such loading conditions.
The aim of this prospective study was to evaluate the efficacy and safety of Platelet Rich Plasma (PRP) injections in patients affected by knee osteoarthritis (KOA). An autologous blood product containing a high percentage of various growth factors (GFs), cytokines and modulating factors as PRP has shown promising results in achieving this goal.
One hundred and fifty-three patients (72 males, mean age 59.06 ± 8.78, range 40-81 years old) from January 2018 to January 2020 received three consecutive PRP injections and completed the follow ups. Western Ontario and McMaster University Osteoarthritis index (WOMAC), Knee society score (KSS) and Visual Analogic Scale (VAS) were evaluated before PRP injection (T0), one month (T1), three months (T2) and six months (T3) after the treatment. All patients underwent baseline and at 6 months MRI and X-ray evaluation.
A statistically significant VAS, KSS and WOMAC reduction emerged in the comparison between evaluations (
< 0.05), MRI demonstrated non-statistically significant improvement in cartilage thickness for both tibial plate and femoral plate (
= 0.46 and
= 0.33 respectively), and no radiographic changes could be seen in any patients.
PRP injection represents a valid conservative treatment to reduce pain, improve quality of life and functional scores even at midterm of 6 months follow-up.

Nevertheless, little research about the metabolic impact of achieving sustained virological response (SVR) is available in HCV/HIV co-infected patients. This research aimed to evaluate early anthropometric, lipid and liver parameters changes after achieving SVR 12 weeks after treatment (SVR12). A real-life retrospective descriptive before-after study assessed 128 DAA treatment episodes from 2015 to 2019 in HCV/HIV co-infected patients. Anthropometric parameters (weight, body mass index), lipid profile, genotype (GT) and viral load, liver data (basics laboratory necroinflammatory parameters and transient elastography (TE)) were collected before treatment with DAA (baseline), and when SVR12 was achieved. Significant increases (p < 0.01) were found in the early lipid profile, measured by LDLc (84.6 ± 35.0 vs. 108.6 ± 35.1 mg/dL) and total cholesterol (161.3 ± 41.0 vs. 183.3 ± 41.6 mg/dL). Significant changes (p < 0.05) were found in liver parameters, measured by ALT (58.2 ± 34.0 vs. 22.0 ± 16.0 U/L), bilirubin (0.8 ± 0.6 vs. 0.6 ± 0.5 mg/dL), albumin (4.2 ± 0.4 vs. 4.3 ± 0.3 g/dL) and liver stiffness (LS) (13.7 ± 13.3 vs. 11.8 ± 12.1 kPa). The main conclusions were that the use of DAA has an early negative impact on lipid metabolism. Achieving SVR12 against HCV leads to an early improvement in liver function and LS in HCV/HIV co-infected patients without interference with antiretroviral treatment (ART) and DAA. Short-term close lipid monitoring may be necessary when combining protease inhibitors. HCV-GT-3/HIV co-infected patients might require further close monitoring for residual fibrosis. These findings can be relevant for actual clinical practice.After the events of 9/11, many police-responders developed post-traumatic stress disorder (PTSD) and were potentially vulnerable to developing depression and/or anxiety; in addition, nearly half of police with probable PTSD had comorbid depression and anxiety. Having in mind that victims who experience the effects of terrorism are exposed to high levels of psychological damage, we thus aimed to determine how sequelae of a terrorist act directly and indirectly affect victims. Quantitative synthesis findings were concluded on the basis of 200 records that met the inclusion criteria out of a total of 650. We grouped the patients according to their level of exposure to the WTC terrorist attack on 11 September 2001. The Level I group included individuals who had experienced the traumatic event and/or those who had observed the attack. The Level II group consisted of rescuers and/or persons who cleaned up debris in the area after the attack. The Level III group comprised the victims' families. Our research enabled us to create a profile for those who were most vulnerable to mental disorders after the WTC terrorist attack. Patients who had survived the terrorist attack and/or those who had observed the incident exhibited fewer traumatic symptoms and a lower percentage of suicidal thoughts in comparison to individuals who had worked as rescuers or cleaning staff in the area after the attack. The number of symptoms rose along with increased contact time with the stressor. The dominant symptom was the triad of intrusion, avoidance, and hyperarousal. The findings may confirm the positive effect of protracted court cases in legal proceedings for compensation on the maintenance and development of psychopathology. Our research may contribute to a better understanding of the consequences of terrorism outcomes on the human psyche and be used in the development of standards for dealing with victims of terrorism's impact.The main symptoms of adenomyosis may adversely affect physical and mental health and quality of life (QOL). However, studies are few on this topic. This study evaluated the effect of adenomyosis on anxiety, depression, and QOL. Participants with adenomyosis (n = 90) or leiomyoma (n = 59) completed questionnaires, including the visual analog scale (VAS) for pain, Hospital Anxiety and Depression Scale (HADS), and Short Form (SF)-36. HADS anxiety and depression positive rates, physical (PCS) and mental (MCS) component summary scores, and eight subscale scores of SF-36 were compared between the two groups. Among patients with adenomyosis, the incidence of anxiety symptoms was 28.9% (control group, 10.2%; OR = 3.589, 95% CI 1.375-9.367), with 10% of patients showing moderate-to-severe symptoms. The incidence of depressive symptoms was 14.4% (control group, 3.4%; OR = 4.812, 95% CI 1.044-22.168). The case group had significantly lower PCS and MCS scores than the control group. In patients with adenomyosis, being employed (OR = 6.393, 95% CI 1.153-35.440) and perianal pain (OR = 25.419, 95% CI 2.504-258.024) were risk factors for anxiety, and perianal pain (OR = 15.208, 95% CI 3.050-75.836) was a risk factor for depression. Compared with leiomyoma, adenomyosis is associated with a higher risk of anxiety and depression, with a poorer QOL.
