To compare the effect of invasive continuous positive airway pressure (CPAP), pressure-controlled ventilation (PCV) with positive end-expiratory pressure (PEEP) and spontaneous breathing (SB) on PaO

, PaCO

and arterial to central venous oxygen content difference (CaO

-CcvO

) in healthy anaesthetized dogs.

Prospective randomized crossover study.

A group of 15 adult male dogs undergoing elective orchidectomy.

Dogs were anaesthetized [buprenorphine, medetomidine, propofol and isoflurane in an air oxygen (FiO

= 0.5)]. All ventilatory treatments (CPAP 4 cmH

O; PCV 10 cmH

O driving pressure; PEEP, 4 cmH

O; respiratory rate of 10 breaths minute

and inspiratory-to-expiratory ratio of 12; SB no pressure applied) were applied in a randomized order during the same anaesthetic. Arterial and central venous blood samples were collected immediately before the start and at 20 minutes after each treatment. Data were compared using a general linear mixed model (p < 0.05).

Median PaO

was significantly ation and CO2 elimination. Greater oxygen extraction occurred with PCV than with CPAP and SB, offsetting its advantage of improved arterial oxygenation. The benefit of invasive CPAP over SB in the healthy anaesthetized dog remains uncertain.Acoustic holograms can encode complex wavefronts to compensate the aberrations of a therapeutical ultrasound beam propagating through heterogeneous tissues such as the skull, and simultaneously, they can generate diffraction-limited acoustic images, that is, arbitrary shaped focal spots. In this work, we numerically study the performance of acoustic holograms focusing at the thalamic nuclei when the source is located at the temporal bone window. The temporal window is the thinnest area of the lateral skull and it is mainly hairless, so it is a desirable area through which to transmit ultrasonic waves to the deep brain. However, in targeting from this area the bilateral thalamic nuclei are not aligned with the elongated focal spots of conventional focused transducers, and in addition, skull aberrations can distort the focal spot. We found that by using patient-specific holographic lenses coupled to a single-element 650-kHz-frequency 65-mm-aperture source, the focal spot can be sharply adapted to the thalamic nuclei in a bilateral way while skull aberrations are mitigated. Furthermore, the performance of these holograms was studied under misalignment errors between the source and the skull, concluding that for misalignments up to 5°, acoustic images are correctly restored. This work paves the way to designing clinical applications of transcranial ultrasound such as blood-brain barrier opening for drug delivery or deep-brain neuromodulation using this low-cost and personalized technology, presenting desirable aspects for long-term treatments because the patient's head does not need to be shaved completely and skull heating is low.

This study analyzed the respective advantages and disadvantages by comparing volumetric modulated arc therapy (VMAT) and intensity modulated radiotherapy (IMRT) on the dose distribution and position verification distribution characteristics in esophageal cancer radiotherapy, in order to provide the reference for the clinical radiotherapy technology optimization of esophageal cancer.

A total of 56 cases of patients with esophageal cancer were selected and applied to the Pinnacle three-dimensional radiation treatment planning system (TPS), in order to design a VMAT plan and IMRT plan under the guidance of image-guided radiotherapy (IGRT). The dosimetry and position verification difference were compared between the two groups.

Revealed that the target dose distribution of the VMAT plan and IMRT plan meets the requirements in clinical dosimetry for all 56 patients in this study. Under the premise of similar target coverage, the conformal index (CI) of the VMAT plan, homogeneity index (HI), target volume, BODY-PTV radiated volume and spinal cord D

, bilateral lung V5, V20 and mean lung dose (MLD), monitor unit (MU) and treatment time (TT), as well as position verification and others, were obviously superior to those in the IMRT plan; and the difference was statistically significant.

CBCT guided VMAT is a potential effective treatment for esophageal cancer and may be more effective and safer than IMRT.

The study aimed to evaluate the impact of sarcopenia on short- and long-term outcomes for laparoscopic colorectal cancer surgery.

Study participants were 209 patients who underwent laparoscopic surgery for any stage of colorectal cancer between 2016 and 2017. Skeletal muscle indices were calculated with preoperative computed tomography. Patients were divided into sarcopenic and non-sarcopenic groups based on index cut-off values and variables were compared.

The prevalence of sarcopenia was 41.1%. Sarcopenic patients experienced shorter operative times and a lower incidence of surgical site infections; however, the incidence of severe postoperative complications and readmission were increased for this group. Although the 3-year disease-free survival rate was not statistically different between groups, sarcopenic patients had a significantly worse 3-year overall survival rate compared with than the non-sarcopenic group.

Sarcopenia has both favorable and unfavorable effects on patients who underwent laparoscopic colorectal cancer surgery.

The objective of this study was to identify response patterns related to sexual well-being following breast operations in the Japanese population.

Patient-reported outcomes were analyzed at 1 year and 5 years after breast operations, including breast reconstruction, for Japanese women at a single center, with a focus on "Sexual well-being" in BREAST-Q. Response analysis and multiple regression analysis were performed. The scores at years 1 and 5 were also compared across three types of operation mastectomy only, TE/Imp, and DIEP.

The response rate for Sexual well-being on BREAST-Q in the prospective cohort of patients with breast cancer dropped from 60.0% in postoperative year 1-34.3% in year 5. The mean score for Sexual well-being increased from 32 (year 1) to 38 (year 5). There were significant differences between respondents and non-respondents in age at year 1 (P=0.007) and for mastectomy only (P=0.01) and TE/Imp (P=0.03) at year 5. In regression analysis, only DIEP was positively associated with Sexual well-being at year 1 (p<0.001) and there were no significant factors at year 5. Among the operative procedures, scores after DIEP were significantly better than those after mastectomy only at year 1 (p<0.001), but there was no difference at year 5. There were no significant changes from year 1 to year 5 for each operation.

A low response rate for Sexual well-being on BREAST-Q was found in Japanese women at 5 years postoperatively. This suggests the need for development of a modified evaluative scale that avoids nonresponse bias and considers ethnic differences.

Therefore, we firstly carried out this meta-analysis aiming to explore the association. We performed a comprehensive literature search online, including PubMed, Embase and Web of Science. We selected deaths at 5 years and hazard ratio (HR) with 95% (CI) to perform the meta-analysis with Review Manager 5.3, predicting value of clinic-pathological features in NSM also been analyzed. A total of 7 studies were finally enrolled in this study. NSM, defined by either JSED criterion or anatomical compartment criterion, neither showed significant prognostic value on OS of esophageal cancer (P = 0.64), (P = 0.24). Subgroup analysis of JSED criterion, NSM was not a prognostic factor in solitary node metastasis patients (P = 0.39), whereas NSM demonstrated a poor prognostic factor (P = 0.01) for ESCC. Subgroup analysis according to anatomical criterion, NSM was a favorable factor for OS in middle thoracic ESCC (P = 0.003). Pathological N1 status was found to be a risk factor for NSM (P less then 0.00001) according to JSED criterion and middle thoracic ESCC was identified as a predictor for NSM (P = 0.0003) according to anatomical compartment criterion. According to JSED criterion, NSM demonstrated poor prognosis on ESCC and N1 status was a risk factor for NSM. Concerning the anatomical compartment criterion, a favorable prognosis of NSM was found in middle thoracic ESCC and NSM was prone to occur in middle thoracic ESCC. (1S,3R)-RSL3 CRD42021219333.

It is unclear whether changes in beverage price and sales after beverage tax implementation can be sustained long term. This study aims to quantify the changes in beverage prices and sales in large retailers 2 years after the implementation of the 1.5 cents per ounce Philadelphia beverage tax.

Data on price and volume sales of beverages and potential food substitutes were collected from 109 supermarkets, 45 mass merchandizers, and 350 pharmacies in Philadelphia, Baltimore (control), and Pennsylvania ZIP codes bordering Philadelphia (to investigate potential cross-border shopping for tax avoidance). Difference-in-differences analyses compared beverage prices and volume sales in the year before tax implementation (2016) to 2 years after (2018). Data were analyzed in 2020-2021.

Difference-in-differences analyses found that after tax implementation, taxed beverage prices in Philadelphia increased by 1.02 cents per ounce (95% CI=0.94, 1.11; 68% pass through), and taxed beverage volume sales in stores decreasn.

Cubital tunnel syndrome is the second most common upper-extremity compressive neuropathy, and persistent symptoms can necessitate operative treatment. Surgical options include simple decompression and ulnar nerve transposition. The cause of wound dehiscence after surgery is not well known, and the factors leading to the development of these complications have not been previously described.

Patients undergoing ulnar nerve surgery from January 1, 2016, to December 31, 2019, were retrospectively evaluated for the development of wound dehiscence within 3 months of surgery. There were 295 patients identified who underwent transposition and 1,106 patients who underwent simple decompression. Patient demographics and past medical history were collected to evaluate the risk factors for the development of wound dehiscence.

The overall rate of wound dehiscence following surgery was 2.5%. In the simple decompression group, the rate of wound dehiscence was 2.7% (30/1,106), which occurred a mean of 21 days (range, 2-generally be treated by allowing healing by secondary intention.

Therapeutic IV.

Therapeutic IV.This review represents our summary of what makes a great collaboration between a surgeon and a scientist. At first, with no perspective, such a collaboration seems easy and natural. But as time goes on, with more perspective, you realize how special it is. Now, in our 60s, with approximately 35 years of collaboration and 75 coauthored papers (most of them in The Journal of Hand Surgery), we are thankful and humbled for this tremendously fruitful and, importantly, enjoyable collaboration. We are not so foolish to think that we made this great collaboration-it was a gift. However, we now recognize many characteristics that make it great and have developed the following 10 tips.
