Cognitive Functioning of Unaffected First‑degree Relatives of Individuals With Late‑onset Alzheimer's Disease: A Systematic Literature Review and Meta‑analysis
First-degree relatives of individuals with late-onset Alzheimer's disease (LOAD) are at increased risk for developing dementia,
yet the associations between family history of LOAD and cognitive dysfunction remain unclear. In this quantitative
review, we provide the first meta-analysis on the cognitive profile of unaffected first-degree blood relatives of LOAD-affected
individuals compared to controls without a family history of LOAD. A systematic literature search was conducted in PsycINFO,
PubMed /MEDLINE, and Scopus. We fitted a three-level structural equation modeling meta-analysis to control for
non-independent effect sizes. Heterogeneity and risk of publication bias were also investigated. Thirty-four studies enabled
us to estimate 218 effect sizes across several cognitive domains. Overall, first-degree relatives (n = 4,086, mean age = 57.40,
SD = 4.71) showed significantly inferior cognitive performance (Hedges’ g = -0.16; 95% CI, -0.25 to -0.08; p < .001) compared
to controls (n = 2,388, mean age = 58.43, SD = 5.69). Specifically, controls outperformed first-degree relatives in language,
visuospatial and verbal long-term memory, executive functions, verbal short-term memory, and verbal IQ. Among the
first-degree relatives, APOE ɛ4 carriership was associated with more significant dysfunction in cognition (g = -0.24; 95%
CI, -0.38 to -0.11; p < .001) compared to non-carriers (g = -0.14; 95% CI, -0.28 to -0.01; p = .04). Cognitive test type was
significantly associated with between-group differences, accounting for 65% (R2
3 = .6499) of the effect size heterogeneity
in the fitted regression model. No evidence of publication bias was found. The current findings provide support for mild but
robust cognitive dysfunction in first-degree relatives of LOAD-affected individuals that appears to be moderated by cognitive
domain, cognitive test type, and APOE ɛ4.University of Otago Doctoral Scholarshi

Comparison of knee sonography and pressure pain threshold after anterior cruciate ligament reconstruction with quadriceps tendon versus hamstring tendon autografts in soccer players
Objective: The aim of this study was to compare the pressure pain threshold and muscle architecture
after an anatomic single bundle reconstruction with quadriceps tendon and hamstring tendon autografts
of the anterior cruciate ligament in competitive soccer players. We hypothesized that both procedures
will obtain similar outcomes.
Methods: Fifty-one participants were enrolled in this secondary analysis of a randomized controlled trial
and were categorised into two groups: quadriceps tendon (QT) group (23 men and 3 women; mean age
18.7 ± 3.6; BMI 23.0 ± 2.2) or hamstring tendon (HT) group (16 men and 9 women; mean age 19.2 ± 3.6
BMI 23.5 ± 3.5). Both groups followed the same rehabilitation staged protocol. Pressure pain threshold
(PPT), as a measure of perceived pain, was obtained in several points of quadriceps and hamstring
muscles. Ultrasound imaging measurements were obtained in quadriceps tendon and knee cartilage
thickness. Four measurements were taken in this study: baseline, 1, 3, 6, and 12 months after the anterior
cruciate ligament (ACL) reconstruction.
Results: The analysis of PPT did not find significant differences in both groups x interaction time in the
points evaluated: epicondyle (QT = 421.1 ± 184.1 vs HT = 384.7 ± 154.1 kPa), vastus lateralis
(QT = 576.2 ± 221.3 vs HT = 560.1 ± 167.7 kPa), vastus medialis (QT = 544.7 ± 198.8 vs
HT = 541.1.1 ± 181.77 kPa), patellar tendon (QT = 626.3 ± 221.1 vs HT = 665.0 ± 205.5 kPa), QT
(QT = 651.1 ± 276.9 vs HT = 660.0 ± 195.2 kPa).
(QT = 667.8 ± 284.7 vs HT = 648.2 ± 193.4 kPa) injured knee (all P > 0.05). The results of ultrasound
imaging did not show significant differences in both groups interaction time in the thickness of the QT
(QT = 9.9 ± 2.4 vs HT = 9.4 ± 1.7 kPa) and patellar cartilage (QT = 3.2 ± 0.6 vs HT = 3.2 ± 0.4 kPa)
(P > 0.05).
Conclusion: A QT autograft produces similar results to a HT autograft in ACL reconstructions in terms of
pressure pain threshold and ultrasound muscle architecture during the 1-year follow-up.

Myofascial Induction Therapy Improves the Sequelae of Medical Treatment in Head and Neck Cancer Survivors: A Single-Blind, Placebo-Controlled, Randomized Cross-Over Study
Head and neck cancer (HNC) is the sixth most common cancer worldwide. Yet, less than
60% of HNC survivors receive adequate therapy for treatment-related sequelae. The objective of this
study was to determine the efficacy of myofascial induction therapy (MIT) in improving cervical and
shoulder pain and range of motion, maximal mouth opening, and cervical muscle function in HNC
survivors. This crossover, blinded, placebo-controlled study involved 22 HNC survivors (average
age 56.55 ± 12.71) of which 13 were males (59.1%) who received, in a crossover fashion, both a single
30-min session of MIT in the form of manual unwinding and simulated pulsed shortwave therapy
(placebo), with a 4-week washout interval between the two. Cervical and shoulder pain (visual
analogue scale) and range of motion (cervical range of motion device and goniometer), maximum
mouth opening (digital caliper), and cervical muscle function (deep cervical flexor endurance test)
were measured before and after the treatment and placebo sessions. A single session of MIT improved
cervical and affected side shoulder pain, cervical range of motion, maximum mouth opening, and
cervical muscle function. The associated effect sizes ranged from moderate to large. The present
study suggests that MIT, in the form of manual unwinding, improves cervical (−3.91 ± 2.77) and
affected-side shoulder (−3.64 ± 3.1) pain, cervical range of motion (flexion: 8.41 ± 8.26 deg; extension:
12.23 ± 6.55; affected-side rotation: 14.27 ± 11.05; unaffected-side rotation: 11.73 ± 8.65; affectedside lateroflexion: 7.95 ± 5.1; unaffected-side lateroflexion: 9.55 ± 6.6), maximum mouth opening
(3.36 ± 3.4 mm), and cervical muscle function (8.09 ± 6.96 s) in HNC survivors.European Regional Development Fund (ERDF) and the

Association between Physiological and Subjective Aspects of Pain and Disability in Post-Stroke Patients with Shoulder Pain: A Cross-Sectional Study
Background: Patients often experience pain as a result of a stroke. However, the mechanism
of this pain remains uncertain. Our aim was to investigate the relationship between pressure pain
thresholds (PPTs) and disability pain in patients with hemiplegic shoulder pain (HSP). Methods:
Twenty-six post-stroke patients (age 53.35 +/- 13.09 years) and healthy controls (54.35 +/- 12.37 years)
participated. We investigated spontaneous shoulder pain, disability pain perception through the
shoulder pain and disability index (SPADI), and the PPTs over joint C5–C6, upper trapezius, deltoid,
epicondyle, second metacarpal, and tibialis anterior, bilaterally. Results: The analysis of variance
(ANOVA) showed significant differences in pain between groups (p < 0.001) and differences in the
SPADI (p < 0.001) between groups but not between sides for PPTs over deltoid (group: p = 0.007;
side: p = 0.750), epicondyle (group: p = 0.001; side: p = 0.848), and tibialis anterior (group: p < 0.001;
side: p = 0.932). Pain in the affected arm was negatively associated with PPTs over the affected
epicondyle (p = 0.003) and affected tibialis anterior (p = 0.009). Pain (SPADI) appeared negatively
correlated with PPTs over the affected epicondyle (p = 0.047), and disability (SPADI) was negatively
associated with PPTs over the affected tibialis anterior (p = 0.041). Conclusions: Post-stroke patients
showed a relationship between widespread pressure pain hypersensitivity with lower PPT levels and
pain disability perception, suggesting a central sensitization mediated by bilateral and symmetric
pain patterns

A Web-Based Exercise System (e-CuidateChemo) to Counter the Side Effects of Chemotherapy in Patients With Breast Cancer: Randomized Controlled Trial
Background: Breast cancer patients have to face a high-risk state during chemotherapy, which involves deterioration of their
health including extensive physical deterioration. Face-to-face physical exercise programs have presented low adherence rates
during medical treatment, and telehealth systems could improve these adherence rates.
Objective: This study aimed to evaluate the effectiveness of a Web-based exercise program (e-CuidateChemo) to mitigate the
side effects of chemotherapy on the physical being, anthropometric aspects, and body composition. Results: Functional capacity improved significantly in the e-CuidateChemo group compared to the control group (6-minute
walk test: 62.07 [SD 130.09] m versus –26.34 [SD 82.21] m; 6-minute walk test % distance predicted: 10.81% [SD 22.69%] m
versus –4.60% [SD 14.58%]; between-group effect: P=.015 for both). The intervention group also showed significantly improved
secondary outcomes such as between-group effects for abdominal (24.93 [SD 26.83] s vs –18.59 [SD 38.69] s), back (12.45 [SD
10.20] kg vs 1.39 [10.72] kg), and lower body (–2.82 [SD 3.75] s vs 1.26 [SD 2.84] s) strength; all P<.001 compared to the control
group.
Conclusions: This paper showed that a Web-based exercise program was effective in reversing the detriment in functional
capacity and strength due to chemotherapy.The study was funded by a research project grant from the Andalusian Health Service, Junta de Andalucia, call for subsidies for
