During Coronavirus disease 2019 (COVID-19) pandemic a reduction in ST-elevation acute myocardial infarction with an increase in in-hospital mortality has been observed. In our region the pandemic temporal trend was sinusoidal with peaks and valleys. A first outbreak was in March 2020, a reduction in May 2020 and a second outbreak in November 2020.

Our hospital was reorganized as one of the 13 Macro-Hubs identified in Lombardy and we retrospectively analysed consecutive STEMI patients hospitalized in the three different phases of COVID-19 pandemic.

We did not register any difference in the number of STEMI hospitalized in the three phases. At multivariate analysis for the entire population COVID-19 infection was the strongest independent predictor of in-hospital mortality. Focusing on COVID-19 patients they experienced a 5-time increased incidence of in-hospital mortality (COVID-19
vs COVID-19
, 47.1% vs 8.6%; p < 0.0001) mainly driven by a higher incidence of respiratory complications (COVID-19
vs COVID-19
, 41.2% vs 6.2%; p < 0.0001) with a similar incidence of cardiac death.

Among STEMI admitted during different phases of pandemic, this study found an increased mortality in patients affected by COVID-19; the co-presence of COVID-19 infection leads to an increase of mortality mostly related to respiratory complications. Interestingly the different incidence in the general population of COVID-19 did not influence the incidence of STEMI.

In conclusion our data suggest the crucial need for an early and precise diagnosis of COVID-19 infection in STEMI to establish a correct management of these very high-risk patients.

The optimal management for Achilles tendon (AT) ruptures is controversial and still continues to encourage debate. Conventionally, operative repair was favoured secondary to its lower rates of re-rupture, however in more recent years, we have seen promising results and a reduction in complications with conservative management. One reason for this improvement may be due to the introduction of a functional weight-bearing orthosis, however, results for complete AT ruptures is still unclear. This study aims to evaluate the functional outcomes of early weight bearing in a functional orthosis for conservatively managed, complete AT ruptures.

This study was done at East Kent Hospital University Foundation Trust in between 2019-2020. In this prospective study, we have analysed data from 41 patients with US diagnosed compete AT ruptures, with a gap less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protoca functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. However, a multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome.

We report a case of Russell's viper bite in an otherwise healthy 55-y-old woman who presented to a hospital in south India with established clinical features of systemic and local envenomation, including coagulation failure, without any neurologic manifestations on admission. She reported simple VH on the third day, which abruptly stopped on the fifth day without any specific medications. Clinical, laboratory, imaging, and electrophysiological studies did not reveal any neuropsychiatric disorders. Including this case, only 5 cases of VH are documented in the literature, 2 following cobra and viper bites and 1 after a sea snake bite. Two cases were reported from Australia and 1 each from the United States, Iran, and India.Flood conditions present dangers for canoe camping, with the highest risk for injury or death related to water submersion of paddlers. Other hazards can exist at high water stages as well. This essay discusses preparation for risks associated with canoe travel during record flood conditions in Alabama's Mobile-Tensaw River Delta. It examines the unique aspects of paddling through submerged forests, route detours necessitated by flooding, potential encounters with dangerous wildlife, and the case of a stinging ant attack on a paddler who unexpectedly comes in contact with a displaced ant colony.
Historically, copperhead snake (Agkistrodon contortrix) envenomations were not treated with antivenom owing to related adverse events and little benefit. However, recent studies have shown improved outcomes with antivenom use. We hypothesized that the frequency of antivenom use for copperhead envenomation in Ohio has increased as benefits of administration became more widely known.

All copperhead snakebites reported to the Ohio poison control centers from 2006 through 2016 were compiled. Antivenom use, bite severity, and disposition were abstracted. A nonparametric test for trend was used to evaluate changes over time for the number of patients treated with antivenom and patient disposition. Logistic regression was used to assess the odds of admission vs discharge with antivenom administration, bite severity, age, and sex as independent variables.

Ninety-eight patients reported copperhead snakebites to the poison control centers. The test of trend showed no change in the proportion of patients treated w, but may lead to an increase in hospital admissions.
Studies show that 40 to 60% of long-distance hikers on the Appalachian Trail experience musculoskeletal (MSK) injuries, but these studies are over a decade old. The increasing popularity of hiking and injury prevention advances warrant re-evaluation of injury patterns. We sought to determine the frequency of self-reported MSK injuries in long-distance hikers on the Appalachian Trail and associations with prehike conditioning and on-trail injury prevention strategies.

The Appalachian Trail Conservancy surveys registered hikers annually. Our orthopedic team added 10 questions specific to MSK injury, training, and equipment to the 2018 to 2019 electronic, cross-sectional Appalachian Trail Conservancy survey. Descriptive statistics and frequencies were calculated. Categorical variables were compared using χ
analysis. Correlations were performed for associations between training and gear and MSK injury. Logistic regression assessed the effect of training on MSK injury. Statistical significance was set at P<0.05.

Of 1295 respondents (52% response rate), 61% (n=791) reported MSK complaints; 28% (n=363) reported overuse/chronic MSK injuries, and 18% (n=238) reported acute injuries. MSK complaints resulted in 11% (n=147) stopping their hike. Respondents who did not train (13%, n=168) were significantly more likely to report an MSK injury (odds ratio 2.82; 95% CI 1.92-4.24; P<0.001). Strength training, stretch/yoga, and endurance training were associated with less injury (all P<0.001). Stabilizing footwear and poles/sticks were associated with fewer MSK complaints (all P<0.001).

Prehike training and hiking gear correlate with fewer injuries. Further research is warranted to elucidate whether promoting injury prevention strategies can reduce MSK injuries among long-distance hikers.

To construct a machine learning (ML)-based model for estimating the alignment curve (AC) curvature in orthokeratology lens fitting for vision shaping treatment (VST), which can minimize the number of lens trials, improving efficiency while maintaining accuracy, with regards to its improvement over a previous calculation method.

Data were retrospectively collected from the clinical case files of 1271 myopic subjects (1271 right eyes). The AC curvatures calculated with a previously published algorithm were used as the target data sets. mTOR inhibition Four kinds of machine learning algorithms were implemented in the experimental analyses to predict the targeted AC curvatures robust linear regression models, support vector machine (SVM) regression models with linear kernel functions, bagging decision trees, and Gaussian processes. The previously published calculation method and the novel machine learning method were then compared to assess the final parameters of ordered lenses.

The linear SVM and Gaussian process machineal lenses, which is especially useful during pandemics, such as that for COVID-19.
Pre-operative biliary bacterial colonisation (bacterobilia) is considered a risk factor for infectious complications after pancreaticoduodenectomy (PD). This study aimed to investigate the role of the PD biliary microbiome grown in the development of post-PD complications.

In a retrospective study of 162 consecutive patients undergoing PD (2008-2018), intra-operative bile cultures were analyzed and sensitivities compared to pre-anesthetic antibiotics and thirty-day post-surgery complications.

Bacterobilia was present in 136 patients (84%). Most bile cultures grew bacteria resistant to pre-operative antibiotics (n=112, 82%). Patients with bacterobilia had significantly higher rates of major complication than patients without (P=0.017), as well as higher rates of surgical-site infections (SSI) (P=0.010). Patients with negative bile cultures (n=26) had significantly lower rates of major complication and SSI than those growing sensitive (n=24) or non-sensitive (n=112) bacteria (major complication P=0.029 and SSI P=0.011).

Positive bile cultures were associated with a higher incidence of major complications and SSI. Patients with sterile bile cultures had the lowest risk of post-operative complications and efforts to reduce rates of bacterobilia, such as limitation of biliary instrumentation, should be considered. Sensitivity to antibiotics had no effect upon the rate of post-operative complications, but this may reflect low cohort numbers.

Institutional human subjects committee approval was obtained prior to initiating this study. This study is a retrospective case series of 58 dancers and 63 ankles who underwent FHL tenolysis/tenosynovectomy via an open posteromedial approach by a single surgeon between 1993 and 2017. All patients were interviewed and charts reviewed. Collected variables included preoperative and postoperative pain levels, time to return to dance, and subjective satisfaction with the procedure. Age, primary dance form, and level of dance were determined. Mean preoperative pain level decreased significantly postoperatively. Mean time to return to dance was 7.1 weeks. There was a 98% (62/63) return to dance at some level while 97% (61/63) of patients returned to dance symptom-free. There were no neurovascular or other major complications. Minor complications included stiffness at follow-up (6.
