Deciphering the Complexity: Addressing Recurrent Hamstring Injury in a Long-Distance Female Athlete.

Hamstring muscle injuries are prevalent in sports, presenting substantial hurdles for athletes and teams due to their high recurrence rates and prolonged recovery periods. The biceps femoris (BF) muscle is frequently implicated in these injuries, with notably high recurrence rates, particularly at the distal musculotendinous T-junction (DMTJ), where half of BF reinjuries occur. This paper presents a case study of a 31-year-old female long-distance athlete with a history of DMTJ rupture, shedding light on the intricacies associated with hamstring injuries. The case underscores the challenges in accurately interpreting imaging findings, reinforcing the need for clinical-imaging correlation and exploration of lesion mechanisms to achieve an accurate diagnosis, optimize outcomes, and facilitate a safe return to sport.

Surviving critical COVID-19: How functionality, physical, mental and cognitive outcomes evolve?

PURPOSE: To analyze the long-term consequences of critical COVID-19, regarding physical, mental, cognitive and functional impairments, and to describe its evolution through time. METHODS: Prospective cohort study, with consecutive inclusion of patients admitted due to SARS-CoV-2 to intensive care units(ICU) of a tertiary-care center, between May/2020 and September/2021. All included patients were included in Physical and Rehabilitation Medicine(PRM) inpatient programs during ICU stay. Eligible patients were evaluated on PRM appointments 6 and 12 months after ICU discharge. In each visit, physical examination and a predefined set of scales were applied, aiming to comprehensively evaluate the three domains (physical, mental and cognitive) of post-intensive care syndrome and the patients' functionality. Statistical analysis encompassed descriptive and univariate analysis. RESULTS: A total of 42 patients were included: 66.7% males, mean age of 62 yo. In the physical domain, 6 months after ICU discharge, there was a significant reduction in quality of life (p-value = 0.034), muscle strength (p-value = 0.002), gait ability (p-value<0.001) and balance (p-values<0.001) and increased fatigue levels (p-value = 0.009), in comparison with reference values. Yet, a significative positive evolution was observed in all referred subdomains (p-values<0.05). Nevertheless, 12 months after discharge, muscle strength (p-value = 0.001), gait (p-value<0.001) and balance (p-value<0.001) were still significantly compromised. Regarding the mental domain, both at 6 and 12 months after discharge, the levels of anxiety and depression were significantly increased (p-values<0.001). Nonetheless, a positive evolution was also found (p-values<0.02). Cognitive performance was significantly impaired in comparison with reference values, both at 6 and 12 months (p-value<0.001). Yet, a global improvement was also depicted (p-value = 0.003). Six months after ICU discharge, 54.8% were autonomous in activities of daily living, a value that improved to 74.0% in the subsequent 6 months (p-value = 0.002). CONCLUSION: Critical COVID-19 survivors present significant physical, mental and cognitive impairments 6 and 12 months after ICU discharge, despite their positive evolution through time.

The PRINCOVID Retrospective Study: A Predictive Model of Pressure Injuries for Critical COVID-19 Patients.

OBJECTIVE: The aim of the study is to characterize pressure injuries, identify risk factors, and develop a predictive model for pressure injuries at intensive care unit admission for critical COVID-19 patients. DESIGN: This study was a retrospective analysis of a consecutive sample of patients admitted to intensive care unit between May 2020 and September 2021. Inclusion criteria encompassed the diagnosis of acute respiratory distress syndrome due to SARS-CoV-2, requiring invasive mechanical ventilation more than 48 hrs. The following predictors were evaluated: sociodemographic characteristics, comorbidities, as well as clinical and laboratory findings at intensive care unit admission. The primary outcome was the presence of pressure injuries. RESULTS: Two hundred five patients were included, mostly males (73%) with a mean age of 62 yrs. Pressure injury prevalence was 58%. On multivariable analysis, male sex, hypertension, hemoglobin, and albumin at intensive care unit admission were independently associated with pressure injuries, constituting the PRINCOVID model. The model reached an area under the receiver operating characteristic curve of 0.71, surpassing the Braden scale ( P = 0.0015). The PRINCOVID score ranges from 0 to 15, with two risk groups: "at risk"(≤7 points) and "high risk"(>7 points). CONCLUSIONS: This study proposes PRINCOVID as a multivariable model for developing pressure injuries in critical COVID-19 patients. Based on four parameters (sex, hypertension, hemoglobin, and albumin at intensive care unit admission), this model fairly predicts the development of pressure injuries. The PRINCOVID score allows patients' classification into two groups, facilitating early identification of high-risk patients.

What is the impact of previous cerebrovascular disease on critical COVID-19 patients' mortality? A prospective cohort study.

OBJECTIVES: We aimed to evaluate the effect of previous cerebrovascular disease (CVD) on mortality rates of critically ill COVID-19 patients. MATERIALS & METHODS: A prospective cohort study was performed between May/2020 and May/2021, at a tertiary-care-center. We consecutively included adult patients admitted to intensive care units (ICU) having as primary diagnosis Acute Respiratory Distress Syndrome due to SARS-CoV-2, requiring invasive mechanical ventilation for >48 h. We considered as exposure the diagnosis of previous CVD and as main outcome the in-ICU mortality. RESULTS: The study sample included 178 patients: 74.2% were males, with a mean age of 63 ± 12.4 years-old(yo). Previous CVD was documented in 17 patients (9.6%). During the study period, the mortality rate at ICU was of 33.1% (n = 59). The proportion of mortality at ICU was higher in patients with prior CVD (58.8% vs 30.4%; p = 0.02). Also, older patients (66 ± 11.4 yo vs. 62 ± 12.7 yo, p = 0.04) and those with higher score at SAPSII at ICU admission (47.8 ± 15.4 vs. 40.7 ± 15.9; p = 0.01) had a higher ICU deathrate. Patients with previous CVD had a 2.70 (95%CI = 1.36-5.39) higher likelihood of dying compared to those who had no previous CVD. After adjustment (for gender, age, SAPSII and total length of stay), multivariate Cox analysis revealed that previous CVD remained a strong predictor for in-ICU death in critically ill COVID-19 patients (HR = 2.51; 95%CI = 1.15-5.51). CONCLUSIONS: Previous CVD was significantly associated to higher mortality in critical COVID-19 patients. We suggest that, in patients with previous CVD, prioritization of vaccination strategies should be implemented alongst with higher surveillance when infected with SARS-CoV-2.
