For the chief surgeon, local pain or dullness (p = 0.603) and eyestrain (p = 0.086) were similar between the LESS-A and CLA procedures. The scopists and assistant surgeons in the LESS-A group did not suffer local pain or dullness (p = 0.793 and p = 0.240, respectively). They did, however, suffer more eyestrain than those in the CLA group (p = 0.001 and p = 0.001, respectively).

Although LESS-A is generally considered to be a technically difficult procedure, the results of this study demonstrate that the feelings of physical fatigue are roughly equivalent between LESS-A and CLA procedures.

Re-operations within 30days after lower gastrointestinal tract surgery are associated to high morbidity and mortality. Laparoscopic approach has been reported as feasible and safe in selected patients, but comparative data to laparotomy are scarce. Birinapant The aim of this study was to review our experience in laparoscopic re-operations and compare it to laparotomy.

From January 2012 to December 2016, patients undergoing a re-operation within one month after lower gastrointestinal tract surgery were included and divided into laparoscopy and laparotomy groups. The primary endpoint was successful re-operation, defined as recovery without any of the following conversion to laparotomy, need of further invasive treatments or death. Secondary outcomes were the length of hospital stay and 30-day morbidity and mortality. Demographic, clinical and surgical characteristics were collected and analyzed.

Out of 114 patients who underwent a re-operation, 71 met the inclusion criteria. Thirty (42%) patients underwent laparoscopy and 41 (58%) laparotomy. Thirty (42%) patients were male and median age was 72.0years-old. The initial operation was elective in 24 (34%) patients, and 50% of the initial operations were colorectal resections in both groups. Multivariate analyses showed that type of approach did not affect the re-operation success rate. Laparotomy was an independent predictor of prolonged hospital stay (OR 3.582, 95%CI 1.191-10.776, p = 0.023) and mortality (OR 13.123, 95%CI 1.301-131.579, p = 0.029).

Re-operations within 30days after lower gastrointestinal tract surgery may be safe in selected patients, as effective as laparotomy, and associated with shorter hospital stay and lower mortality rates.

Management of inflammatory bowel disease (IBD) has changed considerably over recent years, which has coincided with increased subspecialisation amongst general surgeons. This study evaluated the demographics and outcomes of patients with IBD undergoing bowel resection and assessed for the potential impact of surgical subspecialisation.

Patient demographic, operative and outcome data were collected for patients undergoing a bowel resection secondary to IBD, admitted acutely to NHS trusts in the North of England between 2002 and 2016. The primary outcome of interest was 30-day post-operative mortality, with secondary outcomes length of stay, stoma and anastomosis rates.

A total of 913 patients were included in the study cohort. A reduction in the number of resections was noted over time (2002-2006 361 vs. 2012-2016 262). No change was observed for 30-day mortality over the study period (3.9%, p = 0.233). Length of stay was also unchanged (p = 0.949). Laparoscopic surgery was increasingly utilised (0.6% vs. 17.2%, p < 0.001) in recent years, and by colorectal subspecialists (p = 0.003). More patients were managed by a colorectal consultant latterly (2002-2006 45.4% vs. 2012-2016 63.7%, p < 0.001). There was no difference between colorectal and other subspecialists in mortality (p = 0.156), length of stay (p = 0.201), stoma (p = 0.629) or anastomosis (p = 0.659) rates, including following multivariable adjustment.

The study demonstrated a significant reduction in the number of resections over time, increased utilisation of a laparoscopic approach and a shift towards the care of IBD surgical patients being by a colorectal subspecialist. However, these changes do not correspond with improved surgical outcomes.

Six genetic models viz., codominant (AA vs. AB, AA vs. BB and AB vs. BB), dominant (AA+AB vs. BB), completely over dominant (AA+BB vs. AB) and recessive (AA vs. AB+BB) were used to obtain standardized mean difference (SMD) between genotypes. Meta-analysis showed that the gene frequency of A allele (156 bp) was 0.60 (95% confidence interval (CI) 0.54, 0.65). In association analysis, cows with AB genotype [SMD = 0.65, 95% CI 0.00, 1.30] had significantly (P  less then  0.05) higher lactation milk yield (LMY) as compared to BB genotype, whereas AA and AB genotypes had similar trend. Likewise, AA + AB also had larger effect [SMD = 2.31, 95% CI 0.21, 4.10] on LMY as compared to BB. Cows with AB genotype had significantly lower age at first calving (AFC) with small effect [SMD (AA vs. AB) = 1.38, 95% CI 0.06, 2.70] and medium effect [SMD (AB vs. BB) =  - 3.83, 95% CI - 6.41, - 1.24] as compared to cows with AA and BB genotypes, respectively. This finding was confirmed under dominant and completely over dominant models. In case of fat%, AA genotype showed negative effect (SMD =  - 0.51, 95% CI - 0.84, - 0.17) under recessive model. It was concluded that the propagation of allele A is promising to help dairy farmers to improve the genetic quality of their dairy cows.
Microsurgical clipping of previously coiled intracranial aneurysms can be technically challenging. We present the case of a 48-year-old female with a partially coiled, previously ruptured giant middle cerebral artery aneurysm and the associated technical nuances.

We performed a successful coil extraction and clip reconstruction of this aneurysm using an ultrasonic aspirator and stacked fenestrated aneurysm clips.

Coil extraction and clip occlusion of previously coiled intracranial aneurysms is a complex and technically challenging procedure but can be performed safely and effectively when employed judiciously.

Conventional spinal navigation solutions have been criticized for having a negative impact on time in the operating room and workflow. AR navigation could potentially alleviate some of these concerns while retaining the benefits of navigated spine surgery. The objective of this study is to summarize the current evidence for using augmented reality (AR) navigation in spine surgery.

We performed a systematic review to explore the current evidence for using AR navigation in spine surgery. PubMed and Web of Science were searched from database inception to November 27, 2020, for data on the AR navigation solutions; the reported efficacy of the systems; and their impact on workflow, radiation, and cost-benefit relationships.

In this systematic review, 28 studies were included in the final analysis. The main findings were superior workflow and non-inferior accuracy when comparing AR to free-hand (FH) or conventional surgical navigation techniques. A limited number of studies indicated decreased use of radiation. There were no studies reporting mortality, morbidity, or cost-benefit relationships.

AR provides a meaningful addition to FH surgery and traditional navigation methods for spine surgery. However, the current evidence base is limited and prospective studies on clinical outcomes and cost-benefit relationships are needed.

Key hole surgery was recruited for MVD surgery since the maneuver is through the small space between the cerebellum and temporal/occipital bone. However, even small wounds can cause severe postoperative pain if there is significant tissue damage. Attention has been given to the size of the craniotomy rather than to the skin incision or soft tissues such as muscles.

Suboccipital muscle dissection focusing on splitting the splenius capitis muscle was presented. The dura was reapproximated without additional dissection to harvest a fascia graft.

Muscle injury should be minimized to alleviate postoperative pain.

Participants in this longitudinal study were recently diagnosed, predominately late stage, first primary cancer survivors (n = 48). Data collection involved a 30-day period of daily assessment. Data were analyzed using multilevel linear models. As in prior studies, none of the variables changed significantly over time (ps = .07 to .99). Based on the intraclass correlation coefficient, 51 to 75% of the variance in the daily assessment data are attributable to between-person differences. There was a positive relationship between social constraint and both general and cancer-specific distress (ps  less then  .05) and between social support and cancer-specific wellbeing (ps  less then  .001). In prospective models, higher than average general distress predicted higher social support the next day (p = .004) and higher than average cancer-specific wellbeing predicted more social constraint the next day (p = .01). The findings lend some support to the interdependence of social functioning and psychological functioning after cancer diagnosis.
To study the spatial retinal distribution of electroretinographic (ERG) responses that reflect signals in the L-/M-cone-opponent and luminance post-receptoral pathways.

ERG recordings to heterochromatic stimuli (sinusoidal counter-phase modulation of red and green LED light sources) were performed, while varying fractions of red and green modulation. Two temporal frequencies of the stimuli were employed 12Hz to record ERGs that reflect L-/M-cone-opponent signal and 36Hz for recording ERG signals sensitive to stimulus luminance. Stimuli were about 20° in diameter and projected on various retinal locations the fovea and four eccentricities (10°, 19°, 28° and 35°), each presented nasally, temporally, inferiorly and superiorly from the fovea.

The 36 Hz stimuli elicited responses that strongly varied with red fraction and were minimal at iso-luminance. Moreover, response phases changed abruptly at the minimum by 180°. In contrast, the responses to the 12 Hz stimuli had amplitudes and phases that changed more gradually with red fraction.
