“…Interestingly, Malloy et al did not find any side-to-side difference for gluteus medius muscle CSA, an extremely important muscle for frontal-plane hip and pelvic stability during walking. 36 A possible explanation for this might be that sex-specific differences for gluteus medius CSA asymmetry, as found in the current study, could have masked significant muscle atrophy. However, the sample size in the study of Malloy et al was relatively small (n = 50) with an imbalanced sex distribution (64% of women), which could have invalidated the comparison between men and women.…”

“…Muscle atrophy was quantified as the side-to-side percentage asymmetry (hereafter, CSA asymmetry) in single-muscle CSA, calculated as follows: (uninvolved hip – involved hip)/uninvolved hip × 100. For CSA asymmetry, the 10 muscles were also semiarbitrarily grouped according to their primary or secondary function 36 : hip flexors (iliopsoas, tensor fasciae latae, sartorius), hip extensors (gluteus maximus), hip abductors (gluteus medius and minimus), hip adductors (pectineus), and hip external rotators (piriformis, obturator externus, and quadratus femoris). The absolute CSA of each muscle contributing to a given function (eg, gluteus medius and minimus for hip abduction) was summed to provide a total absolute CSA by side.…”

Background: Patients with femoroacetabular impingement syndrome (FAIS) show sex-specific differences in hip muscle function, hip morphology, and symptoms. Possible differences in hip muscle characteristics between men and women with FAIS are unknown. Purpose: To compare hip muscle cross-sectional area (CSA) and fatty infiltration between men and women with FAIS and investigate possible associations with patient-reported outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively analyzed preoperative axial pelvic magnetic resonance imaging scans of 104 patients (54 women) who underwent hip surgery for FAIS. The main outcome measures were side-to-side percentage asymmetry in hip muscle CSA and involved-side fatty infiltration as measured with the Goutallier scale for a total of 10 hip muscles. Patient-reported outcomes included duration of hip symptoms, iHOT-12 (12-item International Hip Outcome Tool), and Hip Sports Activity Scale. Results: Women showed larger hip abductor muscle CSA asymmetry than men ( P = .018), particularly for the gluteus medius ( P = .049), while men exhibited more fatty streaks (grade 1) in the gluteus medius ( P = .015) than women. Duration of symptoms was associated only with fatty infiltration of obturator externus in men ( r S = –0.55, P = .018). iHOT-12 was associated with CSA asymmetry of the gluteus minimus ( r = –0.41, P = .011) and iliopsoas ( r = –0.36, P = .028) in men and with piriformis fatty infiltration ( r S = –0.56, P = .030) in women. The Hip Sports Activity Scale was associated with iliopsoas CSA asymmetry ( r S = 0.32, P = .026) and with fatty infiltration of the tensor fasciae latae ( r S = –0.45, P = .046) and obturator externus ( r S = –0.50, P = .023) in women. Conclusion: Patients with FAIS demonstrated few sex-specific quantitative and qualitative alterations of hip muscles. Women showed greater hip abductor muscle atrophy than men, particularly for the gluteus medius, while men showed a higher degree of fatty infiltration in this same muscle. The duration of hip symptoms was not associated with muscle atrophy. Patient-reported hip pain/function and sport activity level were only moderately associated with isolated muscular variables.

“…Several other coronavirus vaccines have been approved since, and some countries have approved mass vaccination while others have decided to move more cautiously, approving new vaccines for limited or emergency use only. 63 There are still many pending questions. These unknowns include, inter alia, whether or not the vaccine prevents viral transmission, how the vaccine affects different groups, as well as the vaccine's long-term safety profile.…”

Public health decisions in the COVID-19 pandemic require more than ‘follow the science’

Although empirical evidence may provide a much desired sense of certainty amidst a pandemic characterised by uncertainty, the vast gamut of available COVID-19 data, including misinformation, has instead increased confusion and distrust in authorities’ decisions. One key lesson we have been gradually learning from the COVID-19 pandemic is that the availability of empirical data and scientific evidence alone do not automatically lead to good decisions. Good decision-making in public health policy, this paper argues, does depend on the availability of reliable data and rigorous analyses, but depends above all on sound ethical reasoning that ascribes value and normative judgement to empirical facts.
