Assessing Neutrophil-to-Lymphocyte Ratio as a Nutritional Indicator in Community-Dwelling Older Adults.

BACKGROUND: In an aging population, there is an increasing need for easily accessible nutritional markers. AIMS: To determine whether the neutrophil-to-lymphocyte ratio (NLR) can serve as an effective nutritional indicator compared to the Mini-Nutritional Assessment Short Form (MNA-SF) or other common markers such as albumin and body mass index (BMI). METHODS: Data were obtained from the SABE study in Ecuador, which included participants aged 60 years or older. This cross-sectional study collected comprehensive data, including demographics, health-related factors, and physical assessments. Neutrophil and lymphocyte counts were measured by complete blood count. Nutritional status was assessed by MNA-SF, and BMI was calculated. Several physical tests were performed to evaluate the participants' functional status. Confounding variables such as age, sex, and comorbidities were considered. RESULTS: The final sample consisted of 1790 subjects (48.9% male). The overall median age was 68 years (IQR 64,76). BMI and lymphocytes were higher in females, while NLR was higher in males. MNA-SF showed a negative association with NLR. Similarly, lymphocyte count shows a positive association with MNA-SF. Physical tests, such as the Romberg test and the Five Times Sit-to-Stand test, also showed correlations with NLR and lymphocyte count, respectively. CONCLUSION: The study results suggest a significant relationship between NLR and lymphocytes, and nutritional status. The correlation with albumin is stronger with NLR than with BMI. The simplicity and affordability of NLR may make it suitable for routine use in several medical fields, improving our understanding of the complex relationship between nutrition, inflammation, and overall health.

Neutrophil-to-lymphocyte ratio and lymphocyte count as an alternative to body mass index for screening malnutrition in older adults living in the community.

PURPOSE: Accurate height and weight measurement can be challenging in older adults and complicates nutritional status assessment. Other parameters like the neutrophil-to-lymphocyte ratio (NLR) and the lymphocyte count (LC) could be an option to these measurements. We aimed to test these variables as subrogates of body mass index (BMI) or calf-circumference (CC) for malnutrition screening in community-dwelling older adults. METHODS: This is a secondary analysis from the Salud, Bienestar y Envejecimiento (SABE) survey from Ecuador (2009). Includes data on demographics, health-related factors, physical assessments, and complete blood count, allowing to calculate NLR and LC to be used as part of the Mini Nutritional Assessment (MNA), instead of the BMI. Consequently, 4 models were included: standard MNA, MNA-CC, MNA-NLR and MNA-LC. Finally, age, sex, and comorbidities were considered as confounding variables. RESULTS: In our analysis of 1,663 subjects, 50.81% were women. Positive correlations with standard MNA were found for MNA-NLR (Estimate = 0.654, p < 0.001) MNA-CC (Estimate = 0.875, p value < 0.001) and MNA-LC (Estimate = 0.679, p < 0.001). Bland-Altman plots showed the smallest bias in MNA-CC. Linear association models revealed varying associations between MNA variants and different parameters, being MNA-NLR strongly associated with all of them (e.g. Estimate = 0.014, p = 0.001 for albumin), except BMI. CONCLUSION: The newly proposed model classified a greater number of subjects at risk of malnutrition and fewer with normal nutrition compared to the standard MNA. Additionally, it demonstrated a strong correlation and concordance with the standard MNA. This suggests that hematological parameters may offer an accurate alternative and important insights into malnutrition.

Relationships between training dose and record power outputs in professional road cyclists: insights and threats to validity.

Testing short-term (4-8 weeks) correlations between training dose and performance in professional road cyclists can help improve their training and performance. Multilevel mixed-modeling was used to correlate training dose (Time, Edwards' Trimp-eTRIMP, Training Stress Score-TSS, time spent in power output zones-Z1, Z2, Z3, Polarization Index-PI) and Record Power Output (RPO) over 1 minute (RPO1), 5 (RPO5), 20 (RPO20), and 40 minutes (RPO40) across four different time periods: training dose of the previous month with RPOs of the subsequent month (Monthly-analysis); training dose of the 8 weeks preceding All, Grand tours, One-day races with RPOs of these races. In Monthly-analysis, small positive relationships between all the training dose parameters, except for PI, and RPO1, RPO5, RPO20, RPO40 were found (p ≤ 0.001). In Grand tours analysis, Z3 showed a positive association with RPO40 (r: 0.45; p = 0.007, moderate) and was positively related to RPO1 and RPO5 (r between 0.32 and 0.34; p = 0.053-0.059, moderate). PI was small positively related to RPO1 (r = 0.29, p = 0.076, small). In One-day races analysis, eTRIMP was positively related to RPO5 (r = 0.30, p = 0.035, moderate), Z1 negatively related to RPO40 (r = -0.31, p = 0.031, moderate), PI positively related to RPO5 (r = 0.24, p = 0.068, small) and Z2 was negatively related to RPO20 (r = -0.29, p = 0.051, small). A certain degree of responsiveness to training dose exists in professional road cyclists. To improve RPOs an appropriate preparation pattern seems to be increasing high intensity training for Grand Tours and fostering high intensity and overall training load (eTRIMP and TSS) in a more polarized-fashion for one-day races. Systematic and precise data collection during training and racing is highly advocated.

Relationships Between Internal and External Load Measures and Fitness Level Changes in Professional Soccer Players.

Purpose: Understanding the dose-response relationship between internal and external training load with changes in aerobic fitness and intermittent running capacity, during different periods of the season, may help in optimizing training process. The aim of the present study was to investigate the dose-response relationships between load measures and changes in aerobic fitness and intermittent running capacity among a large cohort of professional soccer players. Methods: Training load, aerobic fitness and intermittent running capacity of 52 male adult professional players from 3 elite teams were monitored across an entire season and analyzed employing linear mixed models, with a significance level set at p≤0.05. Results: Relationships between load measures (training and match duration, sRPE-TL, total distance, high and very high-speed running distances) and changes in physical qualities were stronger during the preparation period (PREP) for both aerobic fitness (d= 0.48 to 0.76, p<0.031) and intermittent running capacity (d= 0.46 to 1.89, p<0.046). The magnitude of the relationships reduced during the first competitive period (d= 0.43 to 0.56) and the relationships became trivial in the second competitive period (d= 0.06 to 0.41, p= 0.063 to 0.846). Conclusion: The moderate to large relationships found between all measures of load and changes in physical capacities suggest that training prescription during the PREP was effective in improving players' fitness. During the competitive phase small changes in aerobic and intermittent running capacities were found, highlighting that coaching staff pursue different aims during the competitive period, such as technical and tactical training and recovery.       .

Peripheral muscle function during repeated changes of direction in professional soccer players.

PURPOSES: To evaluate peripheral muscle function of the knee extensors during repeated changes of direction in professional soccer players by examining differences between competitive levels, periods of the season and playing positions, and to investigate the relationships between peripheral muscle function and physical activities during matches. METHODS: Knee extensor peripheral muscle function (twitch peak torque, PT) of 593 male soccer players from 13 European professional clubs competing at 3 different levels was evaluated 4 times during the season. The main outcomes were PTmax (maximal PT, muscle contractility), MPmax (maximal metabolic power exercise intensity) and PTdec (PT decline, muscle fatigability) obtained during intermittent runs of increasing intensity with multiple changes of direction interspersed with electrically evoked contractions. Relative total and sprint distances covered during a whole match and during short intervals were quantified from a sub-sample. RESULTS: PTmax and MPmax were higher for first than for second division (p < 0.047; d = 0.15-0.23) and Under-19 players (p < 0.007; d = 0.17-0.25). MPmax was lower (p < 0.016; d = 0.23-0.32) and PTdec was higher (p < 0.004; d = 0.26-0.39) in the pre-season compared to all the other time points. MPmax was higher for fullbacks than attackers and defenders (p < 0.041; d = 0.20-0.22). PTdec was higher for defenders than fullbacks, midfielders and wings (p < 0.029; d = 0.21-0.28). PTmax was associated with whole-match relative total distance (p = 0.004; d = 0.26). PTdec was associated with whole-match relative total distance and relative short-interval sprint distance (p < 0.050; d = 0.18-0.22). CONCLUSION: The ability to sustain repeated change of direction efforts at high intensities while preserving peripheral muscle function should be considered an important determinant of soccer physical performance.

Impact of COVID-19 Lockdown on Serie A Soccer Players' Physical Qualities.

In March 2020, the COVID-19 pandemic forced most activities in Italy, including soccer, to cease. During lockdown, players could only train at home, with limited evidence regarding the effect of this period. Therefore, this study aimed to investigate the effect of COVID-19 lockdown on professional soccer players' physical performance. Aerobic fitness and vertical jump were assessed before and after four periods in two different seasons: COVID-19 lockdown, competitive period before lockdown, competitive period and summer break of the 2016-2017 season. Linear mixed models were used to examine within-period changes and between-period differences in changes observed during COVID-19 lockdown and the three other periods. Within-period changes in aerobic fitness showed a significant improvement following COVID-19 lockdown (p<0.001) and a significant decline during summer break (p<0.001). Between-period differences were significant in the comparison of COVID-19 lockdown with both the competitive 2019-2020 season (p<0.01) and summer break (p<0.001). For the vertical jump, only the between-period comparison revealed significant differences as the changes associated with COVID-19 lockdown were worse than those of the two competitive periods, for both absolute (p<0.05; p<0.001) and relative peak power (p<0.01; p<0.001). Home-based training during lockdown was effective to improve aerobic fitness, although it did not allow players to maintain their competitive period's power levels.

Impact of COVID-19 lockdown on professional soccer players' match physical activities.

AIM: 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. METHODS: 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. RESULTS: TD and VHS during POST were lower than the two other competitive periods (p < 0.001, d small-moderate). SPR did not show differences between periods (p > 0.636). ACC and DEC during POST were lower than PRE2 (p < 0.015, d small). Declines in most 15-min intervals after lockdown were observed in TD and VHS. CONCLUSIONS: 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.

Influence of ball possession and playing position on the physical demands encountered during professional basketball games.

Understanding the game demands encountered in basketball provides useful insight for developing specific, individualized and team-based training sessions. This study quantified and compared the game activity demands encountered by basketball players of different playing positions: i) strictly when in possession of the ball and ii) overall during live playing time (irrespective of ball possession). The activity demands encountered by 44 (22 guards, 14 forwards, 8 centres) adult, professional, male basketball players were assessed across 10 official games. Time-motion analysis was used to determine the frequency and proportion (%) of playing time performing recovery (REC), low- (LIA), moderate- (MIA), and high- (HIA) intensity activities. Linear mixed models were constructed to examine differences in dependent variables between playing positions, accounting for repeated measures. Guards, forwards, and centres spent 11.9±5.9%, 3.5±1.3%, and 2.9±1.1% of live playing time in possession of the ball, respectively. Guards performed more activities at all intensities (total movements, REC, LIA, MIA, and HIA) than forwards (P < 0.05) and centres (P < 0.05) when in possession of the ball. The proportion of time spent performing HIA in possession of the ball was greater for forwards (P = 0.001) and centres (P = 0.001) than guards. During live playing time overall across games, centres performed more HIA per minute (P = 0.049) and spent a greater proportion of time performing HIA (P = 0.047) than guards. Activities performed when in possession of the ball and during live playing time across basketball games are affected by playing position. These data highlight the need to develop position-specific training drills, particularly with ball possession.

We also found significant differences in presentation symptoms according to whether patients were on palliative care or otherwise

Watch the weathercock: changes in re-staging 18F-FDG PET/CT scan predict the probability of relapse in locally advanced non-small cell lung cancer

Introduction. Induction treatment is be coming the gold standard for locally advanced non-small cell lung cancers (LA-NSCLC). In contrast to baseline positron emission/computed tomography scan (PET/CT scan), re-staging PET/CT scan has been poorly studied in LA-NSCLC. Materials and methods. We retrospectively explored the efficacy of re-staging PET/CT scan to diagnose response and to predict disease-free survival (DFS) in 55 induction-treated LA-NSCLC further treated with curative surgery or radiation but not with adjuvant therapy. Results. Re-staging N status by PET/CT scan significantly correlated with pathological N status. Radiological or metabolic response in the re-staging PET/CT scan was associated with a significantly better DFS, which decreased from 25.8 to 19.3, to 11.2, and to 9.4 months in cN0, cN1, cN2, and cN3 patients, respectively. Conclusion. Re-staging PET/CT scan helps to define response and consolidation treatment in induction-treated LA-NSCLC and predicts DFS. Further extended studies should confirm our results (AU)

Little things make big things happen: angiolymphatic invasion and tumor necrosis prognosticate the outcome of locally advanced non-small cell lung cancer treated with a prior induction therapy.

OBJECTIVES: Size, invasion of thoracic structures, and ipsilateral mediastinal lymph node involvement (pN2) are well-known prognostic factors that configure the staging of resectable, locally advanced non-small cell lung cancer (LA-NSCLC). The prognostic impact of angiolymphatic invasion (ALI) and tumor necrosis (TN) has been barely explored in LA-NSCLC treated with prior induction therapies. METHODS: We retrospectively reviewed 47 resected LA-NSCLCs treated with a prior platin-based chemotherapy or chemoradiation. The impact of ALI, TN, and other pathologic features on survival was analyzed. RESULTS: ALI was presented in 23.4% of cases and TN in 29.8%. Disease-free and overall survival decreased when ALI, TN, or pN2 was present. The incidence of ALI was lower in LA-NSCLC with a good response to induction. CONCLUSION: Our series is the first to report the prognostic impact of ALI and TN in induction-treated LA-NSCLC. The presence of ALI and TN should be included in the pathologic reports.

Age does not worsen the efficacy nor tolerance to combined induction therapies in locally advanced non-small cell lung cancer.

BACKGROUND: One third of non-small cell lung cancer (NSCLC) affects elderly patients in a locally advanced (LA) stage. Induction therapy followed by a curative approach is becoming the standard-of-care for LA-NSCLC. PATIENTS AND METHODS: We compared the efficacy and tolerance to induction chemotherapy or chemo-radiation followed by surgery or definitive radiotherapy in patients younger (N=64) and older (N=44) than 70 years with LA-NSCLC. RESULTS: Elderly patients trended towards having a worse baseline performance status, and presented a higher percentage of IIIB, and squamous tumors. Nevertheless, no significant differences in response rate, operability, or disease-free and overall survival were found between age groups in the whole series, nor in the sub-group of resected patients. Grade 3-4 toxicity tended to be lower in elderly patients. CONCLUSION: Age by itself did not significantly worsen either the efficacy or tolerance to combined induction and definitive treatment in patients with LA-NSCLC and Eastern Cooperative Oncology Group performance status 0-2.

Continued erlotinib maintenance and salvage radiation for solitary areas of disease progression: a usefull strategy in selected non-small cell lung cancers?

PURPOSE: Advanced non-small cell lung cancer (NSCLC) is a common and lethal malignancy that has rarely benefited from chemotherapy. Erlotinib is highly effective in NSCLC patients selected by clinical characteristics and/or the presence of epidermal growth factor receptor-sensitizing mutations. However, the way to delay or bypass erlotinib resistance is not systematically addressed. Different erlotinib-failure modes have been reported in NSCLC, and strategies to prolong erlotinib efficacy are perhaps adaptable to them. We report the feasibility and efficacy of continued erlotinib maintenance and local salvage radiation to overcome erlotinib resistances in selected NSCLC patients. PATIENTS AND METHODS: Thirty of 52 consecutive erlotinib-treated advanced NSCLC from the NYU Langone Medical Center and the Arnau de Vilanova Hospital of Lleida responded initially to erlotinib. Twenty-six patients eventually showed a generalized-progression to erlotinib, and four progressed in solitary tumor sites. These four patients were treated with continued erlotinib maintenance and local salvage radiation. RESULTS: The progression-free survival (PFS) was statistically similar in patients with oligo or generalized-progression to erlotinib. However, all four cases with solitary-progression did benefit from continued erlotinib maintenance and salvage radiation with 41-140 % prolongation of PFS. It was reflected in an improved overall survival when they were compared with patients with generalized-progression (76.4 vs. 19.9 months; p = 0.018). CONCLUSION: Continued erlotinib maintenance and local salvage radiation is feasible and could contribute to a better outcome in selected NSCLC patients with solitary-progression to erlotinib. Prospective randomized trials of this strategy are warranted (AU)
