I’m going to kick off this Doc Gumshoe missive with a little bit of undoubtedly excellent news, albeit information that’s not more likely to have an effect on many voters of Gumshoe Nation. In a nutshell, it’s this: on September twenty sixth, the FDA permitted the primary new drug to deal with schizophrenia in additional than 30 years. The drug is Cobenfy (xanomeline/trospium chloride, a fixed-dose mixture medicine. It was initially developed by Lilly (LLY), which bought the license to Karuna Therapeutics. Karuna has since been acquired by Bristol Myers Squibb (BMY).
Dr Tiffany Farchione, director of the FDA’s Division of Psychiatry, mentioned “This drug takes the primary new strategy to schizophrenia therapy in a long time. This approval affords a brand new different to the antipsychotic medicines folks with schizophrenia have beforehand been prescribed. Schizophrenia is a number one reason behind incapacity worldwide. It’s a extreme, power psychological sickness that’s usually damaging to an individual’s high quality of life.”
For a lot of a long time, therapy of schizophrenia relied on blocking dopamine receptors. Widespread dopamine receptor blockers embody Thorazine (chlorpromazine), Prolixin (fluphenazine), and Haldol (haloperidol). These have been round a very long time. For instance, Thorazine obtained its FDA approval in 1954.
Blocking dopamine receptors has advantages in addition to drawbacks. It reduces signs like hallucinations and paranoia to a degree that sufferers discover livable. However dopamine receptor blockers continuously end in important weight acquire, such that sufferers taking these medicine are inclined to have greater charges of cardiac ailments, leading to lowered life expectancy. And plenty of sufferers have discontinued taking these just because these medicine made them really feel sluggish and unmotivated.
Cobenfy has an impact on dopamine ranges, however its principal goal is one other neurotransmitter, acetylcholine.
About 25 years in the past, the muscarinic acetylcholine receptor agonist xanomeline (which is likely one of the two compounds in Cobenfy) was reported to cut back psychotic signs and enhance cognition in sufferers with Alzheimer’s illness. The antipsychotic and procognitive properties of xanomeline had been subsequently confirmed in a small research of acutely psychotic sufferers with power schizophrenia.
The origins of the phrase “schizophrenia” counsel that the important dysfunction is a mind whose totally different capabilities are basically disjointed – basically a “break up thoughts.”
In accordance with the Nationwide Institute of Psychological Well being, schizophrenia is a psychological dysfunction characterised by disruptions in thought processes, perceptions, emotional responsiveness, and social interactions. Though the course of schizophrenia varies amongst people, schizophrenia is usually persistent and might be each extreme and disabling.
Schizophrenia is comparatively unusual. Within the US, it impacts between 0.25 and 0.75% of the inhabitants. Nonetheless, it’s a disproportionately costly situation. The monetary burden of schizophrenia consists of the direct value of healthcare, which frequently entails life-long institutionalization, but in addition prices comparable to misplaced productiveness, involvement with the prison justice system, and social providers.
Signs of schizophrenia embody psychotic signs comparable to hallucinations, delusions, and thought dysfunction (uncommon methods of pondering), in addition to lowered expression of feelings, lowered motivation to perform objectives, issue in social relationships, motor impairment, and cognitive impairment.
The proof supporting Cobenfy as a therapy for schizophrenia is, thus far, somewhat sparse. There have been solely three managed trials of the drug, and every trial lasted solely 5 weeks. In these trials, Cobenfy lowered the signs of schizophrenia to a manageable degree, with out producing the unwanted side effects linked with dopamine receptor blockers comparable to cardiac illness or weight acquire. BMY launched outcomes of long-term observational research of Cobenfy, during which sufferers didn’t expertise metabolic adjustments or motion issues comparable to affected sufferers taking different medicine to manage schizophrenia.
Pharmaceutical firms are enthusiastic concerning the Cobenfy outcomes, and are engaged on comparable medicines which might be efficient in treating such circumstances as bipolar dysfunction, autism, and Alzheimer’s illness.
BMY has set the wholesale value of Cobenfy at about $22,500 per 12 months. It’s anticipated to generate revenues between $3 billion and $5 billion per 12 months.
Eisai and Eli Lilly conceal circumstances of mind accidents linked to their Alzheimer’s medicine
Clearly, these are genuinely dreadful information objects. The medicine in query are Eisai’s Leqembi (lecanemab) and Eli Lilly’s Kisunia (donanemab). The NY Instances lately devoted greater than a full web page to this case, describing a number of circumstances during which sufferers taking these medicine skilled mind accidents, which might have been anticipated based mostly on their genetic profiles.
In 2021, Eisai put out a name for volunteers to take part in a scientific trial of their experimental drug lecanemab (then referred to as BAN2401) for the therapy of Alzheimer’s illness. Practically 2,000 individuals answered the decision. Eisai sought particularly to incorporate people whose genetic profiles made them particularly prone to develop Alzheimer’s. However these identical people had been extra prone to mind bleeding or swelling in the event that they obtained the drug.
Eisai made a public assertion that each one volunteers can be given a genetic take a look at to determine the precise people who had been at specific danger for mind accidents. Nonetheless, Eisai didn’t inform these trial volunteers that they had been at particularly excessive danger of experiencing these mind accidents. It has been revealed {that a} whole of 274 volunteers joined the trial unaware that they had been at elevated danger. Two of those volunteers died of their mind accidents, and greater than 100 others skilled mind bleeding or swelling.
On July 6, 2023, the FDA granted accelerated approval to Leqembi/lecanemab for the therapy of Alzheimer’s, noting that its modest profit outweighed its dangers. The advantages of Leqembi/lecanemab for the therapy of Alzheimer’s are certainly modest. Remedy with the drug slows cognitive decline for just a few months solely.
The same state of affairs has emerged with regard to Eli Lilly’s anti-Alzheimer’s drug Kisunia (donanemab). Lilly selected to not inform 289 volunteers in a scientific trial of donanemab that their genetic profiles made them particularly weak to mind accidents. A few quarter of volunteers within the Kisunia trials skilled mind swelling or bleeding.
The FDA granted approval to Kisunia virtually precisely a 12 months after Leqembi’s FDA blessing – July 2, 2024.
In each the Leqembi and Kisunia trials, volunteers first needed to signal consent varieties that mentioned that individuals with sure genetic traits confronted greater dangers of mind accidents from receiving the medicine, and that members within the trial can be given genetic checks for these traits. However they had been instructed that they might not be told as to the outcomes.
Basically, the volunteers in these trials had been anticipated to go forward and take part within the trials with out realizing whether or not they had been at elevated danger for mind harm. The folks conducting the trial would know, however the trial topics wouldn’t know.
Each Leqembi/lecanemab and Kisunia/donanemab are BACE inhibitors (beta-site amyloid precursor protein cleaving enzyme inhibitors), that means that they aim amyloid beta, a type of plaque that clogs mind connections. The unlucky Aduhelm/aducanumab (from Biogen), which was taken off the market because of its poor efficiency in addition to the tendency to end in mind bleeds, can be a BACE inhibitor.
Mind bleeding and mind swelling is very prevalent in individuals with the APOE4 gene. About 40% of people with two copies of the gene skilled mind bleeding, and about 35% skilled mind swelling. This gene is very correlated with Alzheimer’s illness. Individuals with one copy of APOE4 have double or triple the chance of growing Alzheimer’s illness, whereas folks with two copies have an eight- to twelvefold enhance in danger.
It ought to be identified that the profit these BACE inhibitors ship is minimal. It slows the onset of dementia in sure Alzheimer’s sufferers for lower than a 12 months earlier than the illness resumes its harmful course.
The annual value of Leqembi/lecanemab is $26,500. For Kisunia/donanemab it’s $32,000. Evidently, neither Eisai nor Lilly wish to allow unlucky particulars, such because the frequency of mind bleeds, to intrude with their gross sales prospects.
A drug-free nasal spray could protect in opposition to respiratory infections
The nasal spray we’re discussing is a gel-like spray formulated with out lively pharmaceutical elements. It has but to be examined in people, however the researchers say it created a protecting coating that lasted for as much as eight hours within the nasal cavities of mice. If the spray’s security and efficacy are confirmed in people, the analysis crew mentioned the strategy might play an vital function in lowering respiratory ailments and safeguarding public well being in opposition to new threats.
The nostril is a typical passage into the physique for a lot of viruses and micro organism. Most respiratory infections, comparable to flu and COVID, are transmitted when an individual inhales tiny droplets of fluid that carry the pathogen. As soon as they get contained in the nostril, the viral or bacterial particles contained in the droplets infect the cells that line the nasal cavity. These pathogens replicate and journey additional down the respiratory tract of the contaminated particular person, generally reaching the lungs, the place they will trigger bronchitis and pneumonia. Pathogens will also be launched again into the air when an contaminated individual sneezes, coughs, laughs, sings, talks, and even simply breathes out and in.
Present nasal sprays provide restricted safety in opposition to respiratory pathogens as a result of they’ve a single mechanism of safety. They both neutralize pathogens or block their entry into the cells lining the nostril, they usually carry out each duties with restricted efficacy.
The projected new drug-free nasal spray was developed to dam germs in 3 ways — the spray varieties a gel-like matrix that enhances the seize of respiratory droplets, immobilizes the germs, blocking their transport into the nasal lining, and successfully neutralizes the germs, stopping an infection. The nasal spray, referred to as Pathogen Seize and Neutralizing Spray (PCANS), was developed with nonpharmaceutical elements already utilized in permitted nasal sprays or listed within the FDA’s Typically Acknowledged as Secure (GRAS) record.
The researchers designed the formulation and studied its means to seize respiratory droplets in a 3D-printed duplicate of the human nasal passages. The experiments confirmed that when administered into the nasal cavity mannequin, the spray captured twice as many droplets as naturally occurring mucus produced as a part of the physique’s innate protection system.
The researchers examined the spray’s protecting results in opposition to a pressure of influenza in mice. The spray was quickly activated following administration into the nostril and lasted as much as eight hours. A single dose might successfully block an infection from an influenza virus at 25 occasions the deadly dose of the virus. Which means the spray was able to averting an infection even when animals had been uncovered to a heavy load of the virus. In accordance with the investigators, virus ranges within the lungs of pretreated animals had been lowered by practically 100% %, in contrast with virus ranges within the lungs of nontreated animals.
The nasal spray was developed by Harvard Medical Faculty researchers working with Brigham and Ladies’s Hospital. The data above got here from a Harvard Medical Faculty launch.
It will be anticipated that the builders of the nasal spray can be extremely captivated with its advantages. Doc Gumshoe’s skeptical flip of thoughts poses a query: even when this superb drug-free nasal spray completed in human topics outcomes similar to these in mice, would strange people be more likely to routinely spray a gel coating into their nasal passages to guard themselves in opposition to pathogens? People who had continuously skilled higher respiratory ailments, or who had been warned that they had been at elevated danger for higher respiratory ailments would possibly use this gadget. Such individuals would possibly take up the behavior of a each day dose of this nostril spray, kind of as a routine follow, like brushing their tooth. I emphasize the phrase “would possibly” in that sentence. It will rely, to a substantial diploma, on what the nostril spray felt like once you press the button or squeeze the tube. Extra considerably, it will rely upon whether or not these people perceived precise enchancment: did spraying gel of their noses really end in fewer circumstances of colds or the flu?
At this second, the protecting nasal spray is a good distance from the scientific trials that might be essential to fulfill the FDA and get the nasal spray permitted as a medical gadget. Designing scientific trials themselves can be a problem. The trial would wish to enlist voluntary topics, a few of whom can be spraying a placebo of their noses. Then, as a way to confirm the efficacy of the nasal spray in stopping an infection, the themes – together with these within the placebo arm – must be uncovered to pathogens, as a way to confirm that the nasal spray lowered an infection. Due to this fact, some trial topics would undoubtedly expertise precise infections. Primarily based on the experimental proof that the gel captured twice as many respiratory droplets as naturally occurring mucus, those that obtained the true nasal spray would presumably expertise infections at half the speed, however they might be uncovered to infectious viruses and micro organism, and if the an infection price matched that within the mice, maybe half of the themes would really get sick. And the an infection price within the placebo group can be twice as excessive.
There could also be methods round this, however it strikes this observer as an extended, lengthy shot.
Attempting to make sense of lengthy COVID
Sure, COVID 19 continues to be with us, though a lot much less of a menace. The latest figures for deaths, hospitalizations, emergency division visits, and constructive checks are means, means down. There have been 444 deaths within the US because of COVID in the course of the week ending November 3. This was about 1.0% of all of the deaths within the US at that time. And solely 0.5% of the emergency division visits had been because of COVID. Listed below are some mortality figures going again to the beginning of the epidemic to supply some perspective concerning the present state.
Week ending 09/14/2024 – 563 deaths because of COVID
Week ending 08/31/2024 – 663 deaths because of COVID
Week ending 05/18/2024 – 336 deaths because of COVID
Week ending 01/27/2024 – 2,131 deaths because of COVID
Week ending 01/17/2023 – 3,870 deaths because of COVID
Week ending 01/15/2022 – 19,078 deaths because of COVID
Week ending 01/19/2021 – 25,974 deaths because of COVID
The parade of variants continues. Presently, the dominant variant nationwide is KP.3.1.1, which accounts for 52% of circumstances, adopted by XEC, with 28% of circumstances, and MC.1, with 6% of circumstances. The unique Omicron variant has been changed by subvariants, together with LB.1, KP.2, and KP.3. As I’ve tediously famous, because the virus mutates, essentially the most “profitable” variants – profitable by way of their very own survival as a viral species – are the variants that allow the human illness sufferer to outlive and move the virus on to different. A virus that kills its victims shortly is doomed to extinction.
All in all, COVID as an acute an infection is receding. However what continues to have an effect on a number of folks, and trigger quite a lot of concern to the healthcare group, is lengthy COVID, which continues to be a puzzle. Lengthy COVID signs are much like the signs of an acute COVID an infection. Generally reported lengthy COVID signs included fatigue, mind fog, muscle ache, joint ache, again ache, headache, sleep disturbance, lack of scent or style, and gastrointestinal signs.
The CDC’s criterion for lengthy COVID is that the virus that causes COVID-19 is “current for a minimum of three months as a steady, relapsing and remitting, or progressive illness state that impacts a number of organ methods.”
In accordance with the CDC, estimates of the prevalence of lengthy COVID differ because of totally different research standards, signs investigated, affected person populations, and timing of when signs are assessed. In 2022, 6.9% of adults and 1.3% of youngsters (roughly 17 million and 1 million, respectively) in america reported ever experiencing lengthy COVID. The latest figures I might discover, dated February fifteenth of this 12 months, ranged from 1.9% within the US Virgin Islands to 10.6% in West Virginia. These are clearly outliers; general, the prevalence remained on the identical degree because it had been in 2022.
I ought to add right here that an AI-enabled strategy, developed by Mass Basic Brigham, means that lengthy COVID prevalence is way greater – about 22%. The algorithm used was developed by drawing nameless affected person information from the scientific data of practically 300,000 sufferers throughout 14 hospitals and 20 group well being facilities within the Mass Basic Brigham system. That algorithm might determine extra individuals who ought to be receiving take care of this debilitating situation.
Whereas lengthy COVID can happen in anybody who will get the coronavirus an infection, some folks or teams of individuals are at greater danger of growing lengthy COVID. These embody girls, folks with underlying circumstances, individuals who skilled extra extreme outcomes of COVID-19, and other people of Hispanic ethnicity. Roughly 1 in 4 adults with lengthy COVID reported experiencing important limitations of their each day exercise.
A research performed by a crew of researchers at Brigham and Ladies’s Hospital centered particularly on lengthy COVID. Researchers discovered folks with wide-ranging lengthy COVID signs had been twice as more likely to have SARS-CoV-2 proteins of their blood, in comparison with these with out lengthy COVID signs.
The crew discovered that 43% of these with lengthy COVID signs affecting three main methods within the physique – the cardiovascular, digestive, and respiratory methods – examined constructive for COVID viral proteins inside 1 to 14 months of their preliminary constructive COVID take a look at. However solely 21% of those that didn’t report any lengthy COVID signs examined constructive for the COVID virus on this identical interval.
The hope expressed by the researchers is that by figuring out a subset of people that have a reservoir of the coronavirus of their our bodies, it might be doable to deal with these individuals with efficient antivirals to alleviate their signs.
The research analyzed 1,569 blood samples collected from 706 people, together with 392 members from the Nationwide Institutes of Well being-supported Researching COVID to Improve Restoration (RECOVER) Initiative, who had beforehand examined constructive for a COVID an infection. Utilizing SIMOA, an ultrasensitive take a look at for detecting single molecules, researchers seemed for complete and partial proteins from the SARS-CoV-2 virus. Additionally they analyzed information from the members’ lengthy COVID signs, utilizing digital medical chart data or surveys that had been gathered concurrently the blood samples had been taken.
Researchers identified that it’s doable {that a} persistent an infection explains some however not the entire lengthy COVID signs. If that is so, testing and therapy might help in figuring out sufferers who could profit from different remedies.
One of many questions raised by the research is why greater than half of sufferers with wide-ranging lengthy COVID signs examined unfavourable for persistent viral proteins.
Dr David Walt, principal investigator on the research noticed that the discovering famous above suggests there may be probably multiple reason behind lengthy COVID. For instance, one other doable reason behind lengthy COVID signs might be that the virus harms the immune system, such that immune dysfunction continues after the virus is cleared.
Dr Walt and his crew are at present conducting follow-up research to raised perceive whether or not an ongoing an infection is behind some folks’s lengthy COVID signs. They’re analyzing blood samples and symptom information in bigger teams of sufferers, together with folks of vast age ranges and people with compromised immune signs. It will be vital to determine people who usually tend to have persistent virus of their our bodies, resulting in lengthy COVID.
The coronavirus inflicting COVID isn’t distinctive in staying within the physique and inflicting ongoing signs months after the preliminary acute an infection. Animal research have discovered Ebola and Zika proteins in tissues post-infection and these viruses have additionally been related to post-infection sickness.
My tackle this matter is that, whereas acute COVID infections are a lot much less frequent and infrequently trigger critical sickness or dying, they will and do result in lengthy COVID, which is an end result to be assiduously prevented. Due to this fact, cautious people (my spouse and myself) proceed to put on masks in some public locations, together with the road on the pharmacy to choose up our medicines and medical amenities.
Who is aware of when – if ever! – it’ll actually and actually be over.
A Division of Power regulation might drastically change our gentle bulbs
That regulation might have a big adversarial impact on the well being of many individuals within the US, particularly epileptics and migraineurs.
The regulation is scheduled to take impact in July 2028, and it’s centered totally on vitality effectivity, as one would anticipate of a regulation coming from the Division of Power. The related assertion is as follows:
“The adopted requirements, that are expressed in minimal lumens (“lm”) output per watt (“W”) of a lamp or lamp efficacy (“lm/W”). These requirements apply to all merchandise manufactured in, or imported into, america beginning on July 25, 2028.”
At current, the one gentle bulbs (“lamps,” within the official DOE parlance) that might meet these requirements are the LEDs that emit gentle within the 460 – 495 nm (nanometer) vary. A nanometer, by the way in which, is a billionth of a meter. Gentle in that vary is emphatically on the blue finish of the spectrum, ranging into the ultraviolet.
However gentle at that frequency has clear and distinct points. Within the night, it messes up our circadian rhythms. Our mind thinks it’s nonetheless broad daylight, undoubtedly not time to fall asleep. Blue gentle suppresses the manufacturing of melatonin, which helps us fall asleep and keep asleep. We’ve all been instructed that staring into our pc screens or watching tv within the half-hour or so earlier than bedtime is a really dangerous concept, as a result of the blue gentle will make it tougher to get an excellent night time’s sleep.
Past the circadian rhythm concern that impacts us all, blue LED gentle is a serious public well being concern for epileptics and migraineurs, lots of whom are extraordinarily delicate to the standard of sunshine and easily can’t tolerate blue LED gentle. Yellow and white LEDs, though problematic, are extra acceptable, however the LEDs on the blue finish of the spectrum are past what these individuals can tolerate.
For these people, even temporary publicity to unnatural gentle, significantly on the blue finish of the spectrum, can set off epileptic seizures and migraine complications. And a migraine is way more and far worse than a nasty headache. Along with the pounding ache, a migraine can convey on different signs, comparable to extreme nausea and vomiting, in addition to excessive sensitivity to any gentle, such that the migraineur must shelter in a darkish room.
The prevalence of migraines within the US inhabitants is surprisingly excessive – virtually 10% of males and about 21% of girls report migraines or exceptionally extreme complications throughout a three-month interval.
What we want is gentle whose frequencies are extra evenly distributed over the seen spectrum, not concentrated on the blue finish. Sure, broader spectrum gentle bulbs are much less vitality environment friendly, however they’re more healthy and far, way more nice.
It’s value stating that we people, together with all different creatures whether or not animal or vegetable, developed with incandescent gentle, and I don’t imply Edison gentle bulbs. The solar and all the celebs in our cosmos emit incandescent gentle, as do candles and torches and cooking fires. Incandescence is gentle produced by any sizzling or burning matter.
The actual high quality of incandescent gentle sources, which can’t be matched by LEDs, is that it emits gentle all through your entire steady spectrum. LED producers could make gentle bulbs that mimic your entire spectrum, mixing diodes that emit radiation at a spread of factors, from the ultraviolet to the infrared. However irrespective of what number of diodes the LED comprises, it won’t be a steady spectrum like incandescent gentle. Elements of the spectrum will probably be lacking, and what we’re capable of see illuminated by LEDs won’t cowl your entire seen spectrum.
In Rockland, Maine, there may be an artwork museum, the Farnsworth, which homes a wonderful assortment of the works of Andrew Wyeth. The Wyeth work are illuminated by LEDs – all apart from one portray which is adjoining to a big window that allows the portray to be lit by daylight. The distinction between the LED-lit work and the one portray close to the window is big. The LED-lit work look drab as compared.
It is likely to be doable to make LEDs which are superior to those within the Farnsworth, however absence of your entire seen spectrum will probably be a deficit. I want to assume that sooner or later the Authorities, whether or not the Division of Power or the Division of Well being and Human Companies, will come to understand that gentle bulbs that span the seen spectrum are, a minimum of in some circumstances, a necessity.
Power-efficient gentle bulbs that emit a nice gentle that may be tolerated by epileptics and migraineurs and are sympathetic to the wants of our circadian rhythms ought to, I deeply hope, change into accessible nicely earlier than that dire date in 2028.
Temporary remark: is Lesstranol the reply to elevated ldl cholesterol?
An everyday reader and web good friend despatched a bit about this complement with the query “Is there something to this?”
My reply is a cautious “possibly.”
The commercial selling Lesstranol isn’t a wild overstatement. Right here is the principal assertion of Lesstranol’s worth:
“After a long time of treating hundreds of sufferers with unhealthy levels of cholesterol, I got here to the conclusion that there needed to be a better all-natural means to assist my sufferers assist their levels of cholesterol. After meticulous analysis, I recognized 1 all-natural key nutrient that helps preserve each regular ldl cholesterol and triglyceride ranges whereas selling optimum LDL/HDL stability and cardiovascular well being.
This key nutrient is Pink Yeast Rice. Historic Chinese language healers believed crimson yeast rice might promote good blood circulation. As we speak, trendy scientists know that it comprises monacolins, substances recognized to advertise regular levels of cholesterol. These monacolins cease the motion of the HMG-CoA reductase, an enzyme that helps make ldl cholesterol.”
Certainly, crimson yeast rice can have a helpful impact on levels of cholesterol. Right here’s what the Mayo Clinic says about it:
“Analysis exhibits that crimson yeast rice containing appreciable quantities of monacolin Ok can decrease your whole blood ldl cholesterol degree, your low-density lipoprotein (LDL, or “dangerous”) ldl cholesterol degree and your triglyceride degree.
Whereas the complement is mostly thought-about secure, it would carry the identical potential unwanted side effects as statin ldl cholesterol medicine.
Pink yeast rice may cost a little lower than a statin. Nonetheless, with a complement, there’s much less assurance relating to high quality and the way a lot lively ingredient is definitely within the product. Some crimson yeast merchandise would possibly comprise solely small quantities of monacolin Ok and doubtlessly have little impact on levels of cholesterol.”
And who is aware of how a lot of that monocolin Ok is within the Lesstranol complement. As has been continuously identified in these items, dietary supplements are totally unregulated. There isn’t any means of realizing what is definitely within the Lesstranol tablets. Talking for myself, if I had elevated ldl cholesterol (which, fortunately, I don’t!), I might comply with the recommendation of my doctor, which might probably level me to a statin.
* * * * * * * *
In previous Doc Gumshoe epistles, we have now mentioned elevated ldl cholesterol and methods of managing that situation, and likewise famous the introduction of recent statins. Is it maybe time to muster up an outline of that image? Please let me know!
I used to be solely capable of cowl just a few of the latest developments on this installment, so within the subsequent one I’ll choose up the place I left off and convey you extra bits and items.
Within the meantime, thanks for all feedback and benefit from the holidays, in addition to the non-holidays. Michael Jorrin (aka Doc Gumshoe).
