This randomized controlled trial tested the effectiveness of the probiotic Bifidobacterium breve BBG-001 in reducing necrotizing enterocolitis, late-onset sepsis, and death in very preterm infants. The trial recruited 1315 infants from 24 hospitals in the UK who were randomly assigned to receive either the probiotic or placebo within 48 hours of birth. The results showed no evidence of benefit for the probiotic intervention in reducing the three primary outcomes of necrotizing enterocolitis, sepsis over 72 hours, or death before hospital discharge. This large, well-designed trial does not support the routine use of this probiotic for very preterm infants.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
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

2. Article to be discussed
Bifi dobacterium breve BBG-001 in very preterm
infants: a randomised controlled phase 3 trial
Kate Costeloe, Pollyanna Hardy, Edmund
Juszczak, Mark Wilks, Michael R Millar, on
behalf of The Probiotics in Preterm Infants Study
Collaborative Group
Published Online November 25, 2015 in
www.thelancet.com
3. Background –What is known?
Probiotics may reduce necrotising enterocolitis and
late-onset sepsis after preterm birth.
However, there has been concern about the rigour
and generalisability of some trials and there is no
agreement about whether or not they should be
used routinely.
4. Lacunae in previous studies
A small number of trials of probiotic in preterm
infants have been performed and the analysis
suggested reduced necrotising enterocolitis and
death, but with no effect on sepsis.
5. NEC in a Glance.
Most serious GI disease of the preterm infant.
Prematurity is the single greatest risk factor.
Approx 10% infants with NEC term.
Pathogenesis is Multifactorial.
Formula feed increases the risk of NEC.
Pneumatosis Coli : Rare & more benign form of NEC
6. BELL Staging for NEC
Stage 1 (Suspected) : Includes clinical signs & symptoms and
nondiagnostic radiographs.
Stage 2 (Definite) : Includes clinical and laboratory signs and
pneumatosis intestinalis and/or portal venous gas on radiographs.
a.Mildly ill
b. Moderately ill with toxicity
Stage 3 (Advanced) : Includes more severe clinical signs and
laboratory abnormalities,Pneumatosis intestinalis, and /or potal
venous gas on radiographs.
a) Critically ill & impending intestinal perforation.
b) Critically ill with pneumoperitoneum.
7. Objective
To test the effectiveness of the probiotic
Bifi dobacterium breve BBG-001 to reduce
necrotising enterocolitis, late-onset sepsis, and
death in preterm infants.
8. Setting
Multicentre randomised controlled phase 3 study,
recruiting infants born between 23 and 30 weeks’
gestational age within 48 h of birth from 24 hospitals
within 60 miles of London in Southeast England.
Between July 1, 2010, and July 31, 2013.
9. Sample Size
A total of 1315 infants were recruited.
Of the total infants selected, 654 were allocated to
probiotic and 661 to placebo.
Five infants had consent withdrawn after
randomisation, thus 650 were analysed in the
probiotic group and 660 in the placebo group
11. Randomisation & Masking
Procedure completed within 48hrs of birth.
Randomly assigned.
Parents, clinicians and outcome assessors were
masked to the treatment allocation.
12. Research in context
This is the first trial systematically to study stool
colonisation in both groups of the trial and to
emphasise both the incomplete colonisation in the
active and the high cross colonisation in the placebo
group.
13. Treatment For
The hypothesis supporting the use of probiotic
bacteria to prevent necrotising enterocolitis and
sepsis is that their administration to the preterm
infant will encourage gut microbiota resembling that
of the term infant, strengthen intestinal barrier
function, and, thereby, protect the infant.
14. Parameters
3 primary outcomes were checked:
1) Any episode of necrotising enterocolitis Bell
stage 2 or 3;
2) Sepsis ( blood culture positive) more than 72 hrs
after birth.
3) Death before discharge from hospital.
17. Analysis of stool culture and PCR results on stools collected
at 2 weeks’ postnatal and 36 weeks’
postmenstrual age
18. Conclusion
There is no evidence of benefit for this intervention
in this population; this result does not support
the routine use of B breve BBG-001 for
prevention of necrotising enterocolitis and late-
onset sepis in very preterm infants.
19. Checklist
Parameter Y/N
Randomization proper
Groups comparable
Other treatment similar
All patients analyzed/ Follow up proper
Blinding proper
Results presented appropriately
Applicability to our practice
•Our patients similar?
•Treatment feasible?
20. Strength
The strengths of this trial are three-fold:
1) First, its size, which combined with the reported
rates of necrotising enterocolitis and sepsis, provide
it with statistical power to give clear answers;
2) The combination of early recruitment, broad
eligibility criteria, and early commencement of the
intervention.
3) Reporting of probiotic stool colonisation rates that
inform the interpretation of the findings.
21. Implication to Practice
The importance of the microbiome in the complex
pathogenesis of necrotising enterocolitis is widely
accepted.
As understanding progresses so the rationale for the
choice of probiotics that might have a therapeutic
role either alone or in combination, and of which
infants might benefit, should strengthen.
The evidence from this trial does not support the
routine administration of probiotics to the preterm
infant.
