Factors influencing midwives' intentions to facilitate normal physiological birth: A qualitative study

BACKGROUND

Whilst most women desire to birth vaginally, research highlights reducing rates of normal physiological birth worldwide. Previous studies have focussed largely on clinical practices associated with vaginal birth however health care professionals' intentions are also known to effect behaviour; a factor not well understood within the context of midwifery and normal physiological birth.

QUESTION/AIM

To explore factors influencing midwives' intentions to facilitate normal physiological birth.

METHODS

A qualitative study using individual interviews was conducted. The Theory of Planned Behaviour was used to develop a semi-structured interview guide to gather perceptions, thoughts, knowledge, and experience of normal physiological birth from participants. Data were analysed thematically within the theoretical constructs: attitudes, subjective norms, and perceived behavioural control.

FINDINGS

Fourteen midwives from various practice settings, models, and locations in Australia were interviewed. Major factors influencing midwives' intentions to facilitate normal physiological birth were influenced by workplace culture, values and influence of leaders, the need to prioritise collaborative interdisciplinary relationships and support autonomy in midwifery.

DISCUSSION

Factors influencing the midwives' intentions of facilitating normal physiological birth were multifaceted. Some influences are more obvious and observable through practice, while others were rooted in underlying beliefs and attitudes that were hidden in the subconscious of those involved. However, all contributing influences ultimately shape midwives' intentions and the way in which they facilitate normal physiological birth.

CONCLUSIONS

Midwives intend to support normal physiological birth; however multiple factors influence their intentions over time. Prioritising collaborative interdisciplinary relationships and supporting autonomy in midwifery could address known barriers.

A Full Bladder Is Not Needed for the Male Stress Incontinence Grading Scale

INTRODUCTION

Our objectives were to evaluate the Male Stress Incontinence Grading Scale to stratify male patients with stress urinary incontinence for either artificial urinary sphincter or sling using a standing cough test and determine if an emptier bladder at the time of assessment carries increased risk of treatment failure.

METHODS

Retrospective chart review of male patients undergoing sling and artificial urinary sphincter placement. The standing cough test score and bladder scan results were documented at initial evaluation.

RESULTS

Forty patients underwent sling and 43 underwent naïve artificial sphincter placement. Median follow-up was 7.11 months. Thirty-six/forty slings had complete incontinence resolution or reduction to a safety pad vs 40/43 after sphincter (90% vs 93%, P = .62). Four sling patients (10%) had persistence or recurrence of incontinence. Cough test scores were similar between sling failure (67% grade 0, 33% grade 1) and success groups (83% grade 0, 3% grade 1, 14% grade 2). Bladder scan mean was 18.5 cc in the sling failure (SD 21.1) and 38.0 cc in the success groups (38.3), with 32% of success patients having bladder scans of 0 cc, and 63% of < 50 cc. Mean for sphincter patients was 45 cc (56.9). Ten patients with scan = 0 and 7 patients with scans < 30 cc demonstrated grade 4 incontinence.

CONCLUSIONS

Cough test is a noninvasive, reliable tool to assess stress urinary incontinence severity. Our data suggest it is reliable even when bladders are nearly empty and can effectively stratify patients for sling vs artificial urinary sphincter with a high rate of success.

Child health nurses' perceptions of the Family Community-based Assistance Resourcing and Education program in contemporary practice: a qualitative study

BACKGROUND

The Family Community-based Assistance Resourcing and Education Program (FCP) is a nurse home visiting program that was introduced in Queensland two decades ago to redress health inequalities for infants from families experiencing specific social stressors. Locally adapted versions of this home visiting program are still in use, but have not been evaluated. This study examined child health nurse perceptions of the adapted FCP in one regional Queensland health service.

METHODS

A qualitative descriptive exploratory study using two focus groups (conducted May 2019) with Child Health Nurses who delivered the FCP was conducted. Transcripts of digital recordings were analysed using Braun and Clarke's (2006) six-step framework for guided thematic analysis.

RESULTS

A total of 16 Child Health Nurses participated in the study, with a mean of 10years' experience with the program. Data analysis generated 12 themes organised under three domains: 'Establishing the relationship with families', 'What works in practice' and 'We could do it better'. Participants cited flexibility, expert input and in-home delivery as key program benefits. However, narrow eligibility criteria, poor screening for perinatal anxiety and resourcing constraints were identified as limitations.

CONCLUSIONS

This study is the first to measure Child Health Nurses' perceptions of an adapted FCP. It sheds light on their 'practice wisdom', including the program's ability to meet the needs of families with social vulnerabilities. The study supports prior calls for home visiting programs to be evaluated against clearly stated program intentions. Participant insights have been shared to inform practice and program implementation both locally and as part of Queensland's First 2000Days health service delivery reform agenda.

Factors associated with spontaneous vaginal birth in nulliparous women: A descriptive systematic review

PROBLEM

Spontaneous vaginal birth (SVB) rates for nulliparous women are declining internationally.

BACKGROUND

There is inadequate understanding of factors affecting this trend overall and limited large-scale responses to improve women's opportunity to birth spontaneously.

AIM

To undertake a descriptive systematic review identifying factors associated with spontaneous vaginal birth at term, in nulliparous women with a singleton pregnancy.

METHODS

Quantitative studies of all designs, of nulliparous women with a singleton pregnancy and cephalic presentation, who experienced a SVB at term were included. Nine databases were searched (inception to October 2022). Two reviewers undertook quality appraisal; Randomised Controlled Trials (RCTs) with high risk of bias (ROB 2.0) and other designs with (QATSDD) scoring ≤ 50% were excluded.

FINDINGS

Data were abstracted from 90 studies (32 RCTs, 39 cohort, 9 cross-sectional, 4 prevalence, 5 case control, 1 quasi-experimental). SVB rates varied (13%-99%). Modifiable factors associated with SVB included addressing fear of childbirth, low impact antenatal exercise, maternal positioning during second-stage labour and midwifery led care. Complexities arising during pregnancy and regional analgesia were shown to decrease SVB and other interventions, such as routine induction of labour were equivocal.

DISCUSSION

Antenatal preparation (low impact exercise, childbirth education, addressing fear of childbirth) may increase SVB, as does midwifery continuity-of-care. Intrapartum strategies to optimise labour progression emerged as promising areas for further research.

CONCLUSION

Declining SVB rates may be improved through multi-factorial approaches inclusive of maternal, fetal and clinical care domains. However, the variability of SVB rates testifies to the complexity of the issue.

Adaptations of an Effective Evidence-Based Pediatric Weight Management Intervention

Current childhood obesity treatment programs do not address medically underserved populations or settings where all members of an interdisciplinary team may not exist-either within one organization or within the community. In this paper, we describe the use of a community-academic partnership to iteratively adapt Epstein's Traffic Light Diet (TLD), into Building Healthy Families (BHF), a community-placed evidence-based pediatric weight management intervention (PWMI) and evaluate its effectiveness in reducing BMI z scores. Nine cohorts of families completed BHF. Participants included children aged 6-12 years with obesity (M = 9.46, SD = 1.74). The Framework for Reporting Adaptations and Modifications-Expanded guided our classification of modifications across BHF cohorts. Using the FRAME reporting structure, the changes that were documented were (1) planned and occurred pre-implementation, (2) based on decisions from local stakeholders (e.g., school administrator, members of the implementation team), and (3) specific to changes in content and context-with a focus on implementation and potential for local scale-up. The nature of the adaptations included adding elements (whole of family approach), removing elements (calorie counting), and substituting elements (steps for minutes of physical activity). Across 9 cohorts, 84 families initiated the BHF program, 69 families successfully completed the 12-week program, and 45 families returned for 6-month follow-up assessments. Results indicated that the BMI z score in children was reduced by 0.31 ± 0.17 at 6 months across all cohorts. Reduction in BMI z score ranged from 0.41 in cohort 4 to 0.13 in cohort 5. Iterative adaptations to BHF were completed to improve the fit of BHF to the setting and participants and have contributed to a sustained community PWMI that adheres to the underlying principles and core elements of other evidence-based PWMIs. Monitoring adaptations and related changes to outcomes can play a role in long-term sustainability and effectiveness.

The implementation of interprofessional education: a scoping review

INTRODUCTION

Implementation of interprofessional education (IPE) is recognised as challenging, and well-designed programs can have differing levels of success depending on implementation quality. The aim of this review was to summarise the evidence for implementation of IPE, and identify challenges and key lessons to guide faculty in IPE implementation.

METHODS

Five stage scoping review of methodological characteristics, implementation components, challenges and key lessons in primary studies in IPE. Thematic analysis using a framework of micro (teaching), meso (institutional), and macro (systemic) level education factors was used to synthesise challenges and key lessons.

RESULTS

Twenty-seven primary studies were included in this review. Studies were predominantly descriptive in design and implementation components inconsistently reported. IPE was mostly integrated into curricula, optional, involved group learning, and used combinations of interactive and didactic approaches. Micro level implementation factors (socialisation issues, learning context, and faculty development), meso level implementation factors (leadership and resources, administrative processes), and macro level implementation factors (education system, government policies, social and cultural values) were extrapolated. Sustainability was identified as an additional factor in IPE implementation.

CONCLUSION

Lack of complete detailed reporting limits evidence of IPE implementation, however, this review highlighted challenges and yielded key lessons to guide faculty in the implementation of IPE.

Nurturing our new midwives: A qualitative enquiry of mentor's experiences of supporting new graduate midwives working in continuity of care models

PROBLEM

Limited opportunity exists for new graduates in Australia to be employed in continuity of care midwifery models.

AIM

To explore the perspectives of midwifery mentors supporting new graduate midwives employed in continuity of care models.

METHODS

An interpretive, qualitative study was conducted. Semi-structured interviews and focus groups with senior midwifery staff who mentored new graduate midwives during their transition to practice within a continuity of care model were undertaken. Digitally recorded and transcribed verbatim, data were thematically analysed. Data collection ceased once theoretical saturation had been achieved. NVIVO software was used to assist with coding and data management.

FINDINGS

Twelve mentors participated. Mentors provided valuable feedback to optimise the supportive mechanisms to enable the success of the rotation of new graduate midwives in continuity of care models during their transition to practice period. Three key themes were constructed, including: Getting it right in the first place; Nurturing our new midwives; and The cultural void.

DISCUSSION

Consistent with the wider literature, effective implementation, sound support structures and wider acceptance of new graduate midwives transitioning to practice within continuity of care models is crucial to its success and sustainability.

CONCLUSION

Mentors are responsible to nurture, respect and guide new midwives through this crucial period, as they transition from midwifery student to registered midwife. Mentors believe in the transition of new graduate midwives in continuity of care models.

Quel impact des évolutions du circuit du médicament sur l’activité de dispensation durant la permanence pharmaceutique ?

INTRODUCTION

Pharmaceutical permanence (PP), outside the working hours of an in-house pharmacy (PUI), allows to guarantee the continuity of care in health-care institutions. A retrospective review of urgent drug dispensing was carried out in the light of changes in the drug circuit.

MATERIALS AND METHOD

The analysis of drug dispensations was performed over a period from 2011 to 2019. The average number of drugs dispensed per shift, annual dispensations, and their variation by day of the week were studied. The increase is statistically significant and is found on both weekdays and weekends. Each drug was identified according to its Anatomical Therapeutic Chemical (ATC) classification. Data on the activities of our institution (number of hospitalizations, average length of stay) were also collected.

RESULTS

In 2011, an average of 36 medications were dispensed per on-call period, compared with 77 in 2019 (a doubling of activity). The increase is statistically significant and is found on both weekdays and weekends. Neurological drugs and anti-infectives represent on average 43 % of the drugs dispensed. At the same time, there was a decrease in average length of stay and an increase in hospitalizations (-10 % and +16 % respectively).

DISCUSSION

The increase in the average number of medications dispensed per shift is notable. It reflects a strong and gradual increase in activity, which was increased when the full vacuum cabinets (FVCs) were introduced, which improved the quality and safety of the pharmaceutical circuit. The revision of the allocations and the information of prescribers on the drug circuit will optimize the activity and refocus it on the pharmaceutical analysis of urgent needs.

Rhino-orbito-cerebral mucormycosis: patient characteristics in pre-COVID-19 and COVID-19 period

Background: Rhino-orbito-cerebral-mucormycosis (ROCM), a rare and potentially fatal disease was seen in increasing numbers during the COVID-19 pandemic. This study describes and compares the patient characteristics and outcomes in COVID-19 associated mucormycosis (CAM) and non-COVID-19 mucormycosis (non-CAM). Methodology: CAM patients (24 cases) were recruited from the COVID-19 period and non-CAM (24 controls) from the pre-COVID-19 period. Clinical data of the CAM group was collected retrospectively with 3 month outcomes prospectively. The non-CAM group data was collected retrospectively. Patient characteristics were compared and risk factors for mortality in ROCM were assessed. Results: Orbital symptoms [altered vision, restricted eye movements, ptosis] and intracranial involvement were higher in CAM patients on presentation. Similarly, the radiological involvement of orbit (orbital apex, superior orbital fissure) and intracranial cavity (intracranial thrombosis, cavernous sinus) was also higher in CAM patients. Newly detected diabetes was found only in CAM patients (29.2%). Although univariate analysis suggested an increased mortality risk in ROCM patients with orbital involvement, the multivariate analysis showed no increased risk with any of the parameters assessed, including COVID-19 positivity. Conclusions: Compared to the non-CAM, the disease presentation was severe in CAM with higher frequency of orbital and intracranial involvement. However, with early detection and treatment, the short term survival was comparable in both groups.

Symptoms of depression in parents after discharge from NICU associated with family-centred care

Aims

The aim of this study was to examine the potential association of family‐centred care as perceived by parents during a NICU stay with parents’ depressive symptoms at discharge and at 4 months corrected for infant age.

Design

A longitudinal, multicentre cohort study was conducted from 2018 to 2020 in 23 NICUs across 15 countries.

Methods

Parents (n = 635 mothers, n = 466, fathers) of infants (n = 739) born before 35 weeks of gestation and admitted to the participating NICUs were enrolled to the study during the first weeks of their infants’ hospitalizations. They responded to Digi‐FCC daily text messages inquiring about their perception of family‐centred care provided by NICU staff. In addition, they completed a questionnaire assessing their overall perception of family‐centred care at discharge. Parents’ depressive symptoms were measured by the Edinburgh Postnatal Depression Scale at discharge and again after discharge when their infants were at 4 months corrected for age.

Results

The mothers’ and the fathers’ perceptions of family‐centred care were associated with their depressive symptoms at discharge and at 4 months corrected age, controlling for gestational age, multiple birth, parent education and relationship status. Parents’ participation in infant care, care‐related decisions and emotional support provided to parents by staff explained the variation in the parents’ perceptions of family‐centred care. The factors facilitating the implementation of family‐centred care included unlimited access to the unit for the parents and for their significant others, as well as amenities for parents.

Conclusions

Our study shows that family‐centred NICU care associates with parents’ depressive symptoms after a NICU stay.

Impact

Depression is common in parents of preterm infants. The provision of family‐centred care may protect the mental well‐being of parents of preterm infants.

1395 The Influence of Shortened Antimicrobial Courses in Surgical Management of Mid 1/3rd Facial Fractures

Aim

Antimicrobial resistance (AMR) is an increasing issue posing a grave threat to global public health. A prospective pilot study within our OMFS unit investigated the effects a shortened course of perioperative antimicrobial cover had on infective post-operative complications in patients who had surgical management of mid 1/3rd facial fractures.

Method

As per the World Health Organisation (WHO) global action plan on antimicrobial resistance, with our microbiology team we developed and implemented a shortened antimicrobial protocol for use in the surgical management of mid 1/3rd facial fractures. Following protocol implementation, the records of 55 patients who underwent surgery for their mid 1/3 facial fractures between May 2019 and May 2020 were reviewed.

Results

Of 55 patients who underwent surgical management of mid 1/3rd facial fractures 28/55 (50.9%) were prescribed a shortened course of perioperative antimicrobials depending on whether an intra or extra oral surgical approach was used, whilst 27/55 (49.1%) were prescribed a longer course of antimicrobials. Of those given a shortened course of antimicrobials 1/28 (3.6%) experienced infective post-operative complications. Conversely 4/27 (14.8%) of those given a longer course of antibiotics experienced infective post-operative complications.

Conclusions

This data supports growing evidence that shorter courses of antimicrobials are appropriate in the surgical management of facial fractures. As OMFS surgeons we can utilise evidence-based medicine to provide optimal surgical care whilst simultaneously contributing to healthcare professionals’ obligations to tackle the increasing challenge of antimicrobial resistance.

Mental toughness and self-efficacy of elite ultra-marathon runners

Minimal research has examined psychological processes underpinning ultra-marathon runners' performance. This study examined the relationships between mental toughness and self-efficacy with performance in an elite sample of ultra-marathon runners competing in the 2019 Hawaiian Ultra Running Team's Trail 100-mile endurance run (HURT100). The Mental Toughness Questionnaire (SMTQ) and the Endurance Sport Self-Efficacy Scale (ESSES) were completed by 56 elite ultra-marathon runners in the HURT100 (38 males, 18 females; Mage = 38.86 years, SDage = 9.23). Findings revealed mental toughness and self-efficacy are highly related constructs (r(54) = 0.72, p < 0.001). Mental toughness and self-efficacy did not significantly relate to ultra-marathon performance (mental toughness and self-efficacy with Ultra-Trail World Tour (UTWT) rank F(2, 53) = 0.738, p = 0.483; mental toughness and self-efficacy with likelihood would finish the HURT100 χ2 = 0.56, p = 0.756; mental toughness and self-efficacy with HURT100 placing and time F(2, 53) = 1.738, p = 0.186 and F(2, 30) = 2.046, p = 0.147, respectively). However, participants had significantly and meaningfully higher mental toughness (M = 45.42, SD = 4.26, medium and large effect sizes) than athletes from other sports previously published. Our interpretation is that these results taken in conjunction, suggest a threshold of mental toughness that performers require to be of the standard needed to be able to prepare for and compete in elite ultra-marathon events such as the HURT100; once this mental toughness threshold is met, other factors are likely to be more influential in determining elite level ultra-marathon performance.

Prevalence and Visual Outcomes of Cataract Surgery in Rural South India: A Cross-Sectional Study

PURPOSE

To determine the prevalence of cataract surgery and postoperative vision-related outcomes, especially with respect to sex, socioeconomic status (SES) and site of first contact with eye care, in a rural area of South India.

METHODS

In a population-based cross-sectional survey of 5530 individuals aged 50 years or older from 10 villages selected by cluster sampling, individuals who had undergone cataract surgery in one or both eyes were identified. Consenting participants were administered a questionnaire, underwent vision assessment and ophthalmic examination. Outcomes were classified as good if visual acuity of the operated eye was 6/18 or better, fair if worse than 6/18 but better than or equal to 6/60, and poor if worse than 6/60.

RESULTS

Prevalence of cataract surgery in this age group (771 persons) was 13.9% (95% confidence interval, CI, 13.0-14.9%). In the 1112 eyes of 749 persons studied, at presentation, 53.1% (95% CI 50.1-56.1%) of operated eyes had good, 38.1% (95% CI 35.2-41.0%) had fair, and 8.8% (95% CI 7.1-10.5%) had poor outcomes. With pinhole, 75.2% (95% CI 72.6-77.8%) had good, 17.2% (95% CI 14.9-19.5%) had fair, and 7.4% (95% CI 5.8-9.0%) had poor outcomes. In 76.3% of eyes with fair and poor presenting outcomes we detected an avoidable cause for the suboptimal visual acuity. Place of surgery and duration since surgery of 3 years or more were risk factors for blindness, while SES, sex and site of first eye care contact were not.

CONCLUSION

The high prevalence of avoidable causes of visual impairment in this rural setting indicates the scope for preventive strategies.

The impact of remote ischemic preconditioning on cardiac biomarker and functional response to endurance exercise

Remote ischemic preconditioning (RIPC; repeated short reversible periods of ischemia) protects the heart against subsequent ischemic injury. We explored whether RIPC can attenuate post-exercise changes in cardiac troponin T (cTnT) and cardiac function in healthy individuals. In a randomized, crossover design, 14 participants completed 1-h cycling time trials (TT) on two separate visits; preceded by RIPC (arms/legs, 4 × 5-min 220 mmHg), or SHAM-RIPC (20 mmHg). Venous blood was sampled before and 0-, 1-, and 3-h post-exercise to assess high sensitivity (hs-)cTnT and brain natriuretic peptide (NT-proBNP). Echocardiograms were performed at the same time points to assess left and right ventricular systolic (ejection fraction; EF and right ventricular fractional area change; RVFAC, respectively) and diastolic (early transmitral flow velocities; E) function. Baseline hs-cTnT was not different between RIPC and SHAM. Post-exercise hs-cTnT levels were consistently lower following RIPC (18 ± 3 vs 21 ± 3; 19 ± 3 vs 23 ± 3; and 20 ± 2 vs 25 ± 2 ng/L at 0, 1 and 3-h post-exercise, respectively; P < 0.05). There was no main effect of time, trial, or interaction for NT-proBNP and left ventricular EF or RVFAC (all P < 0.05). A main effect of time was evident for E which transiently declined immediately after exercise to a similar level in both trials (0.85 ± 0.04 vs 0.74 ± 0.04 m/s, respectively; P < 0.05). In summary, RIPC was associated with lower hs-cTnT levels after exercise but there was no independent effect of RIPC for NT-proBNP or LV systolic and diastolic function. The lower hs-cTnT levels after RIPC suggests that further research should evaluate the role of ischemia in exercise-induced elevation in hs-cTnT.

A clinicopathologic analysis of 88 lung resections of suspected metastatic carcinomas with proven primaries

BACKGROUND

The lung is the most common site for metastatic carcinomas. Very few studies have comprehensively analyzed all pulmonary resections for metastatic carcinomas.

AIMS AND OBJECTIVES

To analyze all lung resections for suspected metastatic carcinomas accrued over 10 years to evaluate: (i). The most frequent primary site,(ii). The interval between primary tumor diagnosis and lung metastases, and (iii). The proportion of inadvertently resected benign lesions, clinicoradiologically mistaken for metastatic deposits.

MATERIALS AND METHODS

Between 2002 and 2011, 88 pulmonary metastasectomies were done for suspected metastatic carcinomas, which form the basis of this study.

RESULTS

In 81 of 88 cases (92%) the diagnosis of metastatic carcinoma was histologically confirmed, whereas 7 cases (8%) were non-neoplastic. The mean interval between primary tumor and metastases was 2.5 years. The primary sites were colorectum (30; 37%), kidney and breast (14; 17.3% each), cervix (9; 10%), salivary gland carcinoma (3), thyroid carcinoma (2), squamous carcinoma (2, one each of mandible and larynx), papillary urothelial carcinoma (2), hepatocellular carcinoma (1), endometrioid adenocarcinoma (1), carcinosarcoma of endometrium (1), adrenocortical carcinoma (1), and neuroendocrine carcinoma (1). The 7 non-neoplastic lesions (8%) histologically revealed tuberculosis (4), bronchopneumonia (2), and aspergillosis (1).

CONCLUSIONS

Almost three fourths (71.6%) of the metastatic pulmonary resections comprised primaries from colorectum, breast and kidney. The interval between primary tumor and metastases ranged from zero months to 10 years (mean 2.5 years). Tuberculosis was the most common histologic diagnosis among the 8% of the non-neoplastic lesions, which were mistaken for metastatic carcinoma on clinical evaluation.

Regional and global left ventricular function following a simulated 5 km race in sports-trained adolescents

The effects of a short, high-intensity bout of exercise on cardiac systolic and diastolic function are not well understood in adolescent athletes. Consequently, the aims of the study were to evaluate global left ventricular (LV) systolic and diastolic function, as well as segmental wall motion responses (cardiac strain), prior to as well as 45 and 225 min following a simulated 5 km cross-country race. Twenty trained, adolescent males (age: 15.2 ± 0.7 years) volunteered for exercise testing. LV fractional shortening and the ratio of early (E) and late (A) peak flow velocities reflected global systolic and diastolic function, respectively. Peak longitudinal mitral annular septal tissue velocities were also determined during systole and diastole. Longitudinal strain (ε) and strain rates were determined across the LV. LV fractional shortening was significantly (P < 0.05) higher at 225 min post-race (37.6 ± 5.8%) compared to pre-race (34.5 ± 4.7%) and 45 min post-race (34.9 ± 5.4 %). This difference was abolished after adjusting for post-race heart rates. There was a significant (P < 0.05) decrease in the E:A ratio at both 45 min (2.04 ± 0.57) and 225 min post-race (2.20 ± 0.66) compared to the pre-race value (2.80 ± 0.68). When these data were adjusted for post-race heart rates, these pre-post-race differences in E:A ratio were abolished. There were no significant alterations in either tissue Doppler velocities or longitudinal ε. The evidence suggests that a 5 km race does not lead to any significant post-exercise attenuation in global or regional LV systolic and diastolic function in trained adolescents.

Seasonal changes in multiple indices of body composition in professional football players

We examined the seasonal variability of indicators of adiposity and generic and population-specific equations of estimating body fat in professional football players. Anthropometric data of 35 outfield players (age, 20±4 years; stature, 1.82±0.06 m; body mass 77.1±7.3 kg) were collected over a playing season. There were a significant main effects for time for all indicators (p<0.001). Post hoc analysis revealed significant changes in body composition between July and mid-August (∑4SF-DW: 1.6 mm, p<0.001; ∑4SF-R: 2.4 mm, p=0.002; ∑5SF: 2.0 mm, p<0.002; ∑8SF: 3.8 mm, p=0.001; Reilly et al.: 0.4%, p=0.001; Durnin and Wormsley: 0.7%, p<0.001). Although all indicators were sensitive to detect small changes in body composition between training mesocycles, we advocate the use of the sum of 4 skinfolds by Reilly et al. to monitor changes in body composition in professional football players; if an estimate of percent body fat is required, the population-specific equation by Reilly et al. may be utilised.
