Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous disorder and Sluggish Cognitive Tempo (SCT) might be a second inattention disorder that might be even affected by different attention pathways. SCT is characterized by daydreaming, mental confusion, staring blankly and hypoactivity. In the present study, we evaluated 5 common variants (rs6265, rs3746544, rs1051312, rs133946 and rs133945) located in 3 candidate genes (

,

and

) that are known to take part in synaptic plasticity and neurotransmitter transmission.

We tested the effects of these variants on neuropsychological findings assessed by a computer-based neuropsychological test battery in children with inattention symptoms (SCT and/or ADHD).

BDNF (rs6265), SNAP25 (rs3746544 and rs1051312) and SYN III (rs133946 and rs133945) polymorphisms were associated with variable cognitive measures.

gene (rs6265) polymorphism Metallele carriers and

gene (rs3746544) T allele carriers had an association with the attention domain.

gene (rs1051312) C allele carriers were only associated with reaction time scores. Cognitive flexibility, which is one of the key components of executive function evaluation and shifting attention test scores were associated with

(rs6265) Metallele and

(rs133946) gene G allele.

(rs133945) gene C allele carriers had an association with verbal memory correct hit scores.

We assessed guilt 3 times a day over a 2-week period via ecological momentary assessment (EMA) technology in 102 children recruited from the community, outpatient, and inpatient settings. The average age of children was 10.95 y.o. (SD = 2.26, range 8-16) and the majority were male (54.9%) and White (76.5%). We found that the real-world guilt during a two-week EMA period was higher among youth with greater suicidal ideation severity in the past six months. Moreover, there was a significant moderating effect of sex and age on this association, such that the association between suicidal ideation severity and guilt was particularly strong among females compared to males and youth who were 10 years old or older. The findings were maintained when we adjusted for the relevant demographic and clinical characteristics, including age, minority status, parental income, EMA response rate, and current internalising symptoms. These preliminary findings highlight the clinical relevance of assessing and targeting feelings of guilt in the day-to-day lives of youth, particularly for females and older youth.

In 2020, the COVID-19 pandemic forced global lockdowns. Herein, we examine the effect of a lockdown exercise programme in a case-study of youth Australian A-league academy football players.

Fifty-five u13-u15 age-grade players were provided with a 110 minute exercise programme including technical, tactical, cardiovascular and muscle strengthening exercises to perform 4 per week at home during the 10-week COVID-19 lockdown.

Pre/Post lockdown, maximum aerobic speed was determined via the 30-15 intermittent fitness test (IFT). Exercise compliance was high (78.5% CI72.2-83.8) with an average of 3.15 sessions completed each week. All time-loss (TL) and medical attention (MA) injuries were recorded. Pre/Post lockdown, no difference in the mean incidence or burden of total time-loss (TL), match TL, training TL or medical attention (MA) injuries or injury rate ratio (1.21CI0.85-2.74) was observed. Similarly, no difference was observed in any injury incidence or burden data or the injury rate ratio (1.53CI0.85-2.74) when comparing the 9-week period prior to lockdown with the first 9weeks post lockdown (9v9 only). A 9.6% (p=<0.01) increase was also observed in Pre/Post 30-15 IFT composite scores (18.7CI 18.3-19.1 to 20.5CI20-21).

In this case study, compliance to the home-based exercise programme was high and no increase in injury was apparent. These findings must however be considered alongside the limitations associated within this case-study.

Inadequate periods of on-pitch football-specific training may underlie the increased injury incidence reported following restart in a non-peer reviewed report. Detraining effects from isolated training are expected, but existing models do not completely describe the unprecedented conditions imposed by COVID-19.Providing insight into specific neuromuscular qualities affected by extended absence of football-specific training, we share countermovement jump performance and kinetic data from an elite team's assessments pre and post 15 weeks of isolated training, and to contextualise these trends, off-season changes with no training.The isolated circuit resistance and aerobic interval training maintained jump height and Reactive Strength Indexmodified, but there were moderate magnitude (p = 0.01-0.04) changes in eccentric 'yielding' and landing 'loading' phase variables. These changes suggest a compromised initiation of countermovement deceleration, impact attenuation and altered coordination/motor control strategies or muscle-tendon properties. This analysis may have revealed kinetic markers specifically stimulated by football-specific training/competition, relevant to post-quarantine monitoring. Lower landing forces may reduce overuse injury risk, while yielding phase alterations suggest a negative effect on reactive performance, therefore the overall effect on vulnerability to injury is unclear.Background We assessed SARS-CoV-2 contamination of random surfaces in football training facilities in an environment with a high prevalence of infections.Methods In six clubs of the Qatar Stars League, surfaces of random locations (high-touch areas, ventilation systems, toilets, cleaning tools, freezers, pantries) in routinely cleaned training facilities, locker rooms, medical and administrative areas were swabbed for SARS-CoV-2. The swabs were screened for the presence of viral RNA using a SARS-CoV-2 qPCR Probe Assay.Results None of the 103 swabs reached a cycle threshold (cT) value ≤30 (strong viral presence, suggestive of potential surface transmission). Four samples showed cT values >30 and less then 35 (low quantity of virus) and 16 swabs returned a cT value ≥35 and less then 40 (inactive virus remnants). The remaining 83 samples were negative (cT value ≥40). Most samples with viral or viral remnant presence originated from high-touch areas.Conclusion We did not find evidence for potential surface transmission in football club facilities when routine cleaning procedures are in place despite the presence of infected subjects.Medical surveillance and risk mitigation protocols to reduce viral transmission have underpinned the return of elite football during the COVID-19 pandemic. learn more This article describes the evidence-informed approach and surveillance findings from the English Football League across a 9-week period at the end of the 2019-20 season. Protocols were devised by the lead EFL Medical Advisor with specialist occupational medicine input. Isolation requirements for cases and contacts were in-line with UK Government regulations, with external contact tracing conducted by local public health authorities. Quantitative PCR testing was conducted twice weekly and within 72 hours of fixtures. Forty-three individuals, including 18 players returned positive tests. No positive results were returned after week 5 (round 10). Our findings support those from other leagues that with appropriate compliance, elite football can continue safely during this pandemic. We recommend that protocols and compliance should be revised as necessary according to community prevalence and changes in viral transmission dynamics.

The COVID-19 pandemic forced the 2019-20 Italian Serie A competition to stop and players went into lockdown. During lockdown, players only trained at home, likely having a detrimental effect on players' physical fitness and capacity. This study investigated the effect of the COVID-19 lockdown on professional soccer players' match physical activities.

Match activities of 265 male professional soccer players were assessed in two periods prior to (PRE1 and PRE2) and one period following the lockdown (POST) using a video tracking system. Linear mixed models were used to examine differences between-periods in total (TD), very high-speed (VHS), sprint (SPR), high-acceleration (ACC) and high-deceleration (DEC) distances, considering full match data and data from six 15-min intervals.

TD and VHS during POST were lower than the two other competitive periods (p<0.001,

small-moderate). SPR did not show differences between periods (p>0.636). ACC and DEC during POST were lower than PRE2 (p<0.015,

small). Declines in most 15-min intervals after lockdown were observed in TD and VHS.

There were small differences in the temporal distribution of SPR, ACC and DEC at POST. After the COVID-19 lockdown, soccer players' higher-intensity running activities were similar to those of games played before the lockdown, but TD and VHS decreased, both considering the entire match and 15-min intervals. The temporal distribution of running activities was mostly stable throughout the season.

To describe high-level footballers' levels and changes in mental health and well-being throughout a 8-week period of lockdown and restricted training during the COVID-19 pandemic.

One-hundred and one players belonging to four teams (women's and men's, first and U19 teams) of the same Italian Serie A club participated in the study. Data were collected through an online questionnaire, and administered at 2, 3, 5, 7 and 9weeks after the start of the lockdown . Well-being, positive and negative affects measurements were examined.

Across the five measures, 36% of players reported clinical levels in depressive symptoms (scores ≤50) on at least one occasion. Thirteen percent of the players reported clinical levels on > 50% of the occasions. There was a decrease in depressive symptoms and negative affects over the period. No change was found in positive affects.

High number of players reportedclinical levels of depressive symptoms compared to what was found previously in high-level athletes. The number decrease during the 8-week period.
