Blood Test For Chronic Fatigue Syndrome
A novel test pairing a laser spectroscopic cell analysis with artificial intelligence capably distinguishes individuals with myalgic encephalomyelitis/chronic fatigue syndrome, ME/CFS, from healthy persons in 91% of cases. British researchers at the University of Oxford studied 61 ME/CFS patients comparing them with 37 healthy controls. After a blood draw, the mononuclear cells of each were studied using single cell Raman spectroscopy to quantitate levels of the amino acids, lipids, cholesterol, glycogen, and glucose within the cells. Number crunching using linear discriminant analysis clearly distinguished ME/CFS patients from normals as well as sorting the ME/CFS patients into those with mild, moderate, and severe disease in 84% of cases.
For years, the high variability of ME/CFS symptoms led some clinicians to be skeptical about the existence of this disorder. Most medical teams now accept the existence of myalgic encephalomyelitis/chronic fatigue syndrome as a real disorder, and this test technique may serve to be identify those who suffer from it.

Extreme Heat During Pregnancy Is Dangerous
During pregnancy, exposure to extreme heat bumps up the risk of severe maternal complications some 27%. California public health researchers led by those at UC-Irvine studied 403,602 pregnancies in women with an average age of 30 years over a 10 year period preceding CoVid. Exposures to hot weather were categorized by intensity of the heat as well as the duration of the exposures.
Exposures of pregnant women to excessive heat above the 80th percentile in terms of severity and duration at any time during pregnancy were associated with those 27% higher risks of severe gestational complications. The risk of problems rose from 32% to 239% as daily maximal temperatures rose from the 75th percentile to the 95th percentile and the exposure durations rose from 2 to 4 days.
With climate change driving ever more frequent heat waves, women considering childbearing must plan for access to fresh, clean, and cool air.

Insomnia Drug May Ease Opioid Withdrawal
From California’s famed Scripps Research Institute comes a study suggesting that a class of insomnia medications may help stunt the symptoms of narcotic withdrawal as well as inhibit drug-seeking behaviors. This preclinical study exposed oxycodone-addicted rats to an experimental dual orexin receptor antagonist drug, DORA-12, which is pharmacologically similar to the FDA approved insomnia medication suvorexant, Merck’s Belsomra.
During a 2 week period following removal of narcotic access, those animals receiving DORA-12 failed to exhibit typical opioid withdrawal symptoms manifest by escalated physical activity as well as increased food and water intake. When given cues to seek more narcotics, the animals on DORA-12 failed to do so. The controls receiving no DORA-12 continued to go through withdrawal.
These results are promising and may spark human studies of dual orexin receptor antagonist drugs such as suvorexant as aids to speed opioid withdrawal and improve its success rates.

Implantable Microsensor Monitors Brain Cancer Chemotherapy Effectiveness
A micro-multichannel syringe carrying a variety of chemotherapeutic agents and implantable into a tumor can help predict the effectiveness of these agents once that tumor is surgically removed. Neurosurgeons and radiologists at Boston’s Brigham and Women’s hospital in collaboration with MIT bioengineers have developed and tested a biocompatible intratumor micro-implant, 6 X 0.7 millimeters, capable of releasing nano-doses of anti-cancer drugs within the tumor. The device delivers these tiny drug doses in spatially discrete zones permitting later analysis of each drug’s effectiveness following tumor resections.
The investigators carried out a preliminary proof-of-concept study of the device on 6 patients, five with glioblastomas and one with an astrocytoma. Each patient received 2 devices at the beginning of their operation which remained in place for 2 to 2.5 hours during tumor removal. A series of 9 drugs were testeed in the study.
The analysis demonstrated that: implantation of these devices was well-tolerated; drug release was consistent; and tumor specimens could be effectively analyzed for drug effect.
Subsequent, larger studies are planned to confirm these findings. In addition, plans are underway to implant these tiny devices into brain tumors non-invasively 72 hours prior to the open surgery in order to observe additional chemotherapeutic effects on the cancer cells.

Diet Drug Treats Both Forms of Diabetes
Semaglutide, the current “it” drug for weight loss, that was initially approved for management of non-insulin requiring diabetes, type 2 diabetes, cuts and even eliminates the need for insulin injections by type 1 diabetics. This small University of Buffalo study was just published in the New England Journal of Medicine.
Endocrinologists there studied 10 recently diagnosed diabetes type 1 patients. Each person was begun on injectable insulin both over the day and at mealtimes but was also given semaglutide. Over a 90 day period during which the semaglutide dose was increased, all were able to eliminate insulin for meals. Over 6 months, 7 of the 10 eliminated the need for any insulin. During the study, the mean HbA1c of the group fell from 11.7 to 5.7. Normal is less than 7
These incredible findings, if confirmed in a larger, randomized, double-blinded study, could revolutionize the management of so-called insulin-dependent diabetes. Stay tuned.

Exercise Could Blunt Alzheimer’s Disease
A new study from Harvard’s Mass General Hospital suggests how the exercise-induced hormone irisin is able to reduce brain levels of the amyloid deposits that are the hallmark of Alzheimer’s dementia. Investigators at the hospital’s Genetics and Aging Unit studied the process in their own ground-breaking Alzheimer’s Disease model using a 3D cell human brain cell culture.
They discovered that the addition to the brain cells of the hormone irisin, normally produced in active muscles, boosts the astrocyte production of the enzyme neprilysin which, in turn, dissolves the chemical hallmark of Alzheimer’s, amyloid. Astrocytes are star-shaped cells with many functions including control of the blood-brain barrier and helping to repair the brain and spinal cord after trauma.
If these findings are confirmed in clinical settings, they could serve the basis for more effective Alzheimer’s Disease therapy. Meanwhile, it’s another reason to keep your body super-active at any stage of life.

Flash Therapy During Sleep May Curb Jet Lag
An hour of flashing light therapy helps reset your biological clock. Stanford psychiatrists report this preliminary yet promising finding after their study of 10 healthy 25 year old volunteers. Each subject took part in two 36 hour sleep lab stays. During one, there was exposure to one hour of repetitive flashing light during the non-REM sleep phase when the brain’s circadian pacemaker in the hypothalamus is most sensitive to light signals without any sleep disturbance. During a second, the control, the subject wore the same flash goggles, but no light therapy was delivered. The result: one hour of flashing light can shift the brain’s biological clock up to 6 hours though there was wide variability with most subjects enjoying a shift of about 68 minutes. This technique could be simplified and commercialized to help you bet jet lag……someday soon.

A tiny implant can detect the temperature changes characteristic of a transplanted organ’s rejection some 3 weeks earlier than conventional signs. Northwestern University nephrologists and bioengineers report that their ultra-thin temperature sensor, smaller than your pinky fingernail and the depth of a hair, placed under a kidney’s capsule layer and attached to an adjacent tiny electronic pack powered by a miniature battery, capably transmits changes in the organ’s internal temperatures to a smartphone via Bluetooth. Animal studies demonstrate that this implant effectively signals organ rejection far faster and more reliably than the traditional blood testing routines. The device is easily implanted during the transplant surgery, and will be tested in humans…….someday soon.

BUSINESS OF HEALTH
3D Printed Medications Customize Dosing
Texas A&M pharmacologists have perfected a method for 3D printing medications with precise dosages in child-friendly shapes and flavors. This technology permits the fabrication of pills that deliver just the proper amount of a drug that works most effectively and safely within a narrow dosing range. Currently, to deliver such doses, adult-sized pills must be crushed and dissolved in liquids in a process called compounding that may cause a deterioration in drug potency. Though 3D pill printing isn’t new, the Texas team has developed a process that eliminates the use of solvents that often shorten shelf life. First creating a drug powder, they mix in a biocompatible polymer, a coloring, and a flavoring before the mix is introduced into the heated print chamber. The tablets are finished with a laser, and studies are now underway to modify this final finishing to create timed release of the contained medication.

Toronto Company Perfects Plant-based Salmon
The Canadian startup, New School Foods, has perfected a plant-based salmon that looks, cooks, flakes, and tastes like the real thing all without any hooks, lines, or sinkers. Though the product is only now available in a beta-test form, it is created with proprietary processes that create aligned muscle fibers, connective tissues, and other components. Beginning “raw,” the pseudo-salmon is cookable, and its omega 3 fatty acids impart the taste of wild salmon. This product, when available, will join the ranks of “Impossible,” “Beyond,” and other-branded meats and dairy alternatives.
