1) A study found that recreational athletes who drank a flavored ice slurry (-1°C) before running on a treadmill in hot conditions (34°C) could run for an average of 50 minutes until exhaustion, 9 minutes longer than those who drank cold water (4°C).
2) The ice slurry lowered athletes' core body temperature more before exercise compared to cold water, allowing them to store and dissipate more heat during running.
3) While the effects were short-lived and may not last for longer endurance events, ice slurries provide an easy, practical pre-cooling method to improve performance in hot conditions for sports like tennis or 5K races.
Cold water inmersion reduces anaerobic performanceFernando Farias
Many athletes compete in multiple events on the
same day such as heats and semifinals or round
robin competitions. Under these circumstances,
effective recovery is essential to ensure optimal
performance in a subsequent event or match. A
variety of recovery techniques exist including
cryotherapy (cold water immersion/ice baths,
ice massage, ice packs), whirlpool therapy, mas-
sage and contrast therapy.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Ice Slurry Ingestion Increases Core Temperature Capacity and
Running Time in the Heat
SIEGEL, RODNEY; MATÉ, JOSEPH; BREARLEY, MATT B.;
WATSON, GREIG; NOSAKA, KAZUNORI; LAURSEN, PAUL B.
Abstract
Purpose: To investigate the effect of ice slurry ingestion on
thermoregulatory responses and submaximal running time in the
heat.
Methods: On two separate occasions, in a counterbalanced order,
10 males ingested 7.5 g·kg−1 of either ice slurry (−1°C) or cold
water (4°C) before running to exhaustion at their first
ventilatory threshold in a hot environment (34.0°C ± 0.2°C, 54.9%
± 5.9% relative humidity). Rectal and skin temperatures, HR,
sweating rate, and ratings of thermal sensation and perceived
exertion were measured.
Results: Running time was longer (P = 0.001) after ice slurry (50.2
± 8.5 min) versus cold water (40.7 ± 7.2 min) ingestion. Before
running, rectal temperature dropped 0.66°C ± 0.14°C after ice
slurry ingestion compared with 0.25°C ± 0.09°C (P = 0.001) with
cold water and remained lower for the first 30 min of exercise.
At exhaustion, however, rectal temperature was higher (P =
0.001) with ice slurry (39.36°C ± 0.41°C) versus cold water
ingestion (39.05°C ± 0.37°C). During exercise, mean skin
temperature was similar between conditions (P = 0.992), as was
2. HR (P = 0.122) and sweat rate (P = 0.242). After ice slurry
ingestion, subjects stored more heat during exercise (100.10 ±
25.00 vs 78.93 ± 20.52 W·m−2, P = 0.005), and mean ratings of
thermal sensation (P = 0.001) and perceived exertion (P = 0.022)
were lower.
Conclusions: Compared with cold water, ice slurry ingestion
lowered preexercise rectal temperature, increased submaximal
endurance running time in the heat (+19% ± 6%), and allowed
rectal temperature to become higher at exhaustion. As such, ice
slurry ingestion may be an effective and practical precooling
maneuver for athletes competing in hot environments.

To Beat the Heat, Drink a Slushie First
Robert Dant
By GINA KOLATA
It’s no surprise that it’s hard to exercise on a hot day. You go
slower. An easy workout is grueling. You have no endurance.
Well
The reasons are also no surprise. Blood is directed to the skin for
cooling, which means it is diverted from working muscles. The
hotter it is, and the harder the effort, the harder exercise
becomes. Eventually, you slow down or stop, unable to go on.
Exercise physiologists debate why. It could be that muscles are
starved for blood. It could be that the brain gets too hot. It
could be that the heart eventually can’t beat fast enough to
satisfy all the demands for blood. But even without knowing why,
3. researchers have found they can delay the time to utter
exhaustion by getting people a bit chilled before they start.
So companies sell devices, like cooling vests to wear before
exercise, or even portable cold baths for prerace immersion.
Researchers have tested methods like having athletes swim for
an hour in cold water or sit in a cold room or stand in a cold
shower. No matter what the method, companies and researchers
report a precooling effect.
The problem is that none of the methods are easy, cheap and
practical. But now, a New Zealand endurance athlete and exercise
researcher says he has found a method that is. All you have to do
is drink an ice slurry, also known as a slushie, before exercising.
In a new study, he reports that young male recreational athletes
who drank a syrup-flavored ice slurry just before running on a
treadmill in hot room could keep going for an average of 50
minutes before they had to stop. When they drank only syrup-
flavored cold water, they could run for an average of 40 minutes.
There are limitations — the running test was indoors, so there
was no cooling effect from breezes on the skin. In those artificial
circumstances, precooling might have had more dramatic effects
than it would outdoors. And what athletes really want is to go
faster in a race, not run until they drop. But the study tested
endurance, not performance, which is typical of such research.
Still, exercise specialists say, the effect was pronounced. “It’s a
really interesting study, well done and carefully thought out,” said
Craig Crandell, an exercise physiologist at the University of
Texas Southwestern Medical Center, who studies the effects of
exercising in the heat.
4. The effect was short-lived, according to the senior investigator,
Paul Laursen, at the New Zealand Academy of Sport in Auckland
and a competitor who has raced in 13 Ironman triathlons (a 2.4-
mile swim followed by a 112-mile bike race followed by a
marathon-distance 26.2-mile run). It would not even begin to last
long enough to run a marathon or do a century (100-mile) bike ride,
for example. But it would be perfect for a sport like tennis or for
a 5- or 10-kilometer race or for team sports like soccer or
football, and it might give endurance athletes in longer events a
boost by letting them beat the heat, to a certain extent, for the
first 50 minutes or so.
Dr. Laursen said he thought of using ice slurries because they can
lower brain temperature in swine more effectively than cold
water. The swine studies were testing methods to cool the body
before surgery. Dr. Laursen reasoned that slurries might also
effectively cool the body before exercise. The advantage, he said,
is that they are even colder than ice — 30 degrees Fahrenheit —
an effect that occurs when sugary water is swirled with crushed
ice.
“It’s a neat idea,” said Scott Montain, an exercise researcher at
the United States Army Research Institute of Environmental
Medicine in Natick, Mass. “I wouldn’t have guessed slurries would
have that much of an effect.”
It’s not so clear why ice slurries or any other method work,
though. As Dr. Laursen notes in a review article, “The mechanisms
underlying the performance effects associated with precooling
are not yet completely understood.” One possibility, which Dr.
Laursen said might have explained the ice slurry results, was that
slurries lowered body temperature before the young men ran,
letting them run for a longer time before their bodies became
5. critically hot.
Dr. Montain is not sure. The men did not get that hot, he said. At
exhaustion, the mean body temperature of those who drank the
slurry and those who drank cold water was about 101 degrees.
He said the limiting factor might have been the men’s heart rates.
In both groups, exhaustion occurred when heart rates reached
about 185 beats per minute. Those who drank the slurry hit that
heart rate 10 minutes later than those who drank cold water. Dr.
Montain says the heart beats faster and faster, trying to get
blood to the skin, for cooling, and to the muscles for exercising,
until it just can’t keep up.
“The heart can’t send blood everywhere without the blood
pressure falling,” Dr. Montain said. “At some point, you can’t
maintain your blood pressure.” But, Dr. Montain said, what
mattered in the end was that the simple solution of drinking an
ice slurry worked. He might even try drinking a one himself if he’s
stuck racing in the heat, something he tries to avoid.
“I try to race when the weather is good,” Dr. Montain said. “I live
in Massachusetts, so I can choose.”
Dr. Crandall, in Dallas, might seem the ideal person to use a slurry
before a run. But he’s less interested.
“I just run for enjoyment,” he said. And if he drank a slurry with
its sugary syrup, he said, “all the calories I burned off would be
added back.” Dr. Laursen, though, is drinking slurries. He gets ice
cream headaches when he drinks them — everyone does, he said
— but he puts up with the pain. It’s worth it.
6. When he has a slurry before a grueling bout of exercise in the
heat, he said, “I feel so much better.”
