Fall Mushroom Foray in the Wasatch Mountains!

 

Here it is again… fall mushroom season in Utah!

This foray was to the Wasatch Front in early September. Even at 8,000’, it was pretty warm out, and I wondered if we would find anything.  Dry grasses and forbs crunch-crunched underfoot in an un-promising manner.

Then my footsteps fell silent as I approached a small stream. This moist micro-habitat, it turned out, was full of mushrooms! Great find!

Here’s some Cortinarius mushrooms, members of a very large genus which is identifiable by weblike remnants of a cortina on their stems. The cortina is a delicate structure that covers the gills, coming away as the mushroom matures. In the third picture below, a bit of cortina can be seen, still connecting stipe to cap.

 

Fungi are just about the only organisms that can decompose lignin, a key component of wood. If not for the vast amount of lignin-digesting fungi that inhabit the woods, we would be awash in dead and down logs in perpetuum. Chunky “brown rot”, below, is left behind by organisms that only consume cellulose. “White rot” fungus consumes both lignin and cellulose, leaving a pale residue.

Brown rot

White rot

 

Here is Lacterius deliciosa. The lacterius genus oozes white “milk” from their gills when damaged. In this case, deliciosa is a misnomer- this mushroom will make you sick.

 

Below is Sarcodon – the shingled hedgehog. An easy-to-recognize edible mushroom with a unique musky, minty odor. Some like it and some don’t. They are better young, becoming bitter when older. The hedgehog has teeth instead of gills or a polypore structure.

 

Below is a picture of Cryptospore fungus on a tree trunk. Beetles crawl into the fungal case to feed, and are covered in spores, which they carry to a new tree.

 

On the overhanging banks of the stream, hiding amongst mosses, were charming little bright orange Scutellinia scutelata “eyelash mushrooms”. Under a magnifying glass, these tiny orange cups are fringed by eyelash-like hairs.

 

Porcini bolete- the Utah state mushroom is a large, choice edible! It can be recognized by its polypore underside, reticulum on stem, and “penny bun” cap. It is mycorrhizal, often found under younger spruce trees.

 

The bolete was followed by a couple of rare finds: elven saddles! Top photo is a white one, and the black one in the lower photos may be a new species.

Fringe Ecosystems: Ghost Grass and the Sonoran Desert

"One day, Ghost Grass will cover everything, and that's the way the world will end"

-Ser Jorah Mormont, quoting a Dothraki legend, Game of Thrones. 

 On a recent hike through the Sonoran desert, the warm air and fantastic shapes of the cactus around me made it easy to imagine I was diving on a tropical reef. At the same time, I had a strange feeling I was in Africa. Numerous acacia trees created classic Africa skyline sillouettes, and beneath them waved a sea of amber grass. The grass was fully cured, the air was 110 degrees, and monsoonal lightning storms were approaching. Minus the cactus, it looked just like West Africa during the harmattan/fire season.

 But, unlike many Sahel ecosystems, the Sonoran Desert is not fire adapted. It seemed like this impossibly combustible cocktail should have done in the slow-growing saguaros and other cacti long ago. Some research proved the resemblance to Africa wasn't coincidental; African and Mediterranean fire-adapted grasses have invaded the Sonoran Desert, threatening ecological catastrophe. 

 The real-world equivalent of Game of Throne's Dothraki Ghost Grass consists of a sinister trio: Cheat Grass, Buffle Grass, and Red Brome. For Western Deserts, the 19th-century introduction of these old-world grasses was, arguably, the most ecologically consequential event since the last Glacial Period.

 Adapted to Mediterranean and African conditions, inluding drought and wildfire, these grasses outcompete American species, such as sage and native bunchgrass. Cheatgrass, Red Brome, and Buffel grass create soil characteristics unfavorable for native desert plants. Drying out early into continous fuel bed, they carry wildfire across desert landscapes, where plant spacing used to prevent fire from spreading. Invasive grasses have spread throughout the West, from Texas to California, and the Dakotas to Arizona. Below, a field of invasive red brome fills in the spaces between saguaros.

The NPS publishes the guide, seen below, to identifying and eradicating Red Brome. The eradication options (hand-pulling bunches of grass, or five years of annual herbicide application) may work for individual homeowners. Unfortunately, the idea of implementing these on a large-enough scale to protect the vast stretches of Sonoran Desert which have been invaded by Red Brome is laughable.

Arizona and New Mexico are home to the southern fringe of many landscapes, including Ponderosa Forests, Pinyon-Juniper forests, and the Sonoran Desert. These fringe forests represent species inhabiting the southern end of their range- a range that is shifting northwards due to climate change. These days, the unhappy theme of each of my wildfire assignments here seems to be the complete destruction- by fire- of fringe ecosystems that were already stressed by climate change, pollution, and overgrowth, and competition with invasives. Natural forest succession cycles and climactic range shifts occur at too rapid a pace for nature's coping mechanisms to keep up. A forest that used to burn in a mosaic of 5-acre fires over 100 years burns today in a single, 500,000-acre blaze. No refuges for wildlife are left, the soil is baked to clay. When the rains return, no animals remain to greet it from unburned refuges, no green islands of trees are left to reseed the soil. Without roots to retain it in place, the soil is washed away into vast, destructive debris flows. 

 Fringe forests convert to fields of brush, deserts to fields of Ghost Grasses- and fire is the final catalyst.

Ukraine: Jogging in Circles and Red Viburnum Tea

Staying fit during winter in the Eastern half of Ukraine can be challenging. Fortunately I've worked out a combination of pilates and jogging around a UXO- and stray-dog-free circuit. Twenty laps equals two miles. The background noise of local air defense artillery at work has become easy to ignore. 

Winter is setting in in earnest; after a cold run, its a good time for a cup of vitamin-C rich Red Viburnum Tea. Crushed viburnum berries and honey are a traditional remedy for colds in Ukraine. The berries can also be eaten raw in small quantities or made into jams and pies. For example, the viburnum genus is large and widespread. New-world viburnums, also known as high-bush cranberries, were used by Native Americans as a vitamin-C-rich winter food.

Pensions are very small in Ukraine, so it's extremely common for pensioners to set up small tables on the sidewalk in town to sell home-grown produce. This time of year, a grandmother might sell butternut squash, jam, or jars of pickled vegetables. Some folks spend all afternoon sitting out in the cold, just to sell a few bunches of Red Viburnum berries. When in town, I try to buy from pensioners and small shopkeepers, rather than line the pockets of supermarket-owning "mini-oligarchs".

Viburnum is not just a common hedgerow bush here; it's a national symbol of Ukraine. "Chervona Kalina" ("Red Viburnum") is an old Ukrainian folk song (lyrics below). Its first stage performance occurred in the 1914 Stepan Charnetsky play "Sun of Ruin". Popularized by the play, it became the anthem of the Ukrainian Sich Rifleman unit, which fought for Austria-Hungary. In 1944, Chervona Kalina was made into an arrangement by Ukraine National Chorus director Oleksander Koshets. Koshets made "Carol of the Bells" famous in the US, during the Chorus's post-WWI world tours. The tours were intended to promote Ukrainian culture and garner support for the Ukrainian Independence cause, after the Bolshevik invasion. 

Chervona Kalina has been extremely popular with Ukrainian soldiers, both during WWII and the current war. It is effectively a second national anthem for modern Ukraine.

Here is a youtube link to a 2022 version performed by Pink Floyd Chervona Kalina, with Pink Floyd  

Chervona Kalina, lyrics:

In the meadow, a red kalyna

In the meadow, there a red kalyna, has bent down low ,

For some reason, our glorious Ukraine, has been worried so.

And we'll take that red kalyna and we will raise it up,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

And we'll take that red kalyna and we will raise it up,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

 

Do not bend low, Oh red kalyna, You have a white flower.

Do not worry, glorious Ukraine, You have a free people.

And we'll take that red kalyna and will raise it up,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

And we'll take that red kalyna and will raise it up,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

 

Marching forward, our fellow volunteers, into a bloody fray,

For to free, our brother - Ukrainians, from hostile chains.

And we, our brother - Ukrainians, we will then liberate,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

And we, our brother - Ukrainians, we will then liberate,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

 

In the field, of early spring wheat, there's a golden furrow,

Then began, the Ukrainian riflemen to, engage the enemy,

And we'll take, that precious, early wheat and will gather it,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

And we'll take, that precious, early wheat and will gather it,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

 

When the stormy winds blow forth from the wide steppes,

They will glorify, through out Ukraine, the Sich riflemen.

And we'll take the glory of the riflemen preserving it,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

And we'll take the glory of the riflemen preserving it,

And we, our glorious Ukraine, shall, hey - hey, cheer up - and rejoice!

Ukraine: How Long can a Tourniquet be left in place before the limb must be amputated?

Prospects for limb salvage after tourniquet placement has become a crucial matter for thousands of soldiers and their surgeons in the Ukraine war. Near-peer fighting conditions and lack of air superiority can create extended evacuation times for casualties. Drone threats to moving vehicles have become so pervasive that, in many areas, the last few miles up to the zero line area only traversable on foot. Beyond this zone, mud, bombing damage, UXOs, and the impossibility of road maintenance make vehicle evacuation slow and bumpy. Patients must often wait for nightfall to evacuate, and dawn-dusk day length at the height of summer on the Eastern Front is 17 hours. Today, almost two years into the war, high attrition rates amongst experienced frontline medics means loss of TCCC tourniquet conversion knowledge along the frontline. 

For medics and doctors in forward casualty collection and stabilization points, who are receiving tourniqueted patients after prolonged evacuations from a near-peer conflict area, assessing patient candidacy for tourniquet conversion (i.e. removal and replacement with a simple pressure dressing) or movement of tourniquet to a more distal location is a critical outcome-changing skill. Just as important as assessing limb salvageability is 1) readiness to manage acute complications such as acidosis and dysrhythmias, and 2) ensuring that timely transfer to higher-level care is available for potential medium-term complications, such as compartment syndrome and acute renal failure. 

Current TCCC guidance assumes that limb salvage becomes highly unlikely 6 hours or more after tourniquet placement. However, this guidance is unavoidably based on the extremely limited data pool available to date. Limb salvage after tourniquet placement is a young and weak science, which stands to benefit greatly from case reporting and retrospective studies originating from the Ukrainian conflict. If we look only at the small pool of my personal experience as a paramedic in Ukraine, several case examples of physician-directed conversions of tourniquets in place for over 6 hours have been performed, or given post-conversion management, by either myself or my immediate colleagues. Clearly, amputating every limb that has been touniqueted for more than 6 hours would result in unnecessary negative life impacts for patients.

Current tourniquet science is based on animal studies done in controlled environments, and a very small number of human case reports. Tourniquets are widely used in routine surgeries, but tourniquet use in traumatic wartime injuries is a completely different animal. The reality of warfare adds in a number of important and unforeseen variables, which defy efforts to cleanly categorize patients as <6 hours vs >6 hours:

1) initial tourniquet placement is likely to occur under extreme conditions. Often, the soldier placing the tourniquet has minimal medical training, may be physically and/or mentally exhausted (many Ukrainian soldiers have been deployed for nearly 2 years with little or no leave). He or she may be receiving fire and/or returning fire, and may be working in conditions of darkness, loud noise, and confusion. The soldier placing the tourniquet may have reduced fine motor control due to cold, exhaustion, or adrenaline, or may be injured themselves. Weather and fighting conditions may have led to heat exhaustion, dehydration, nutritional deficits, soaked clothing, icy gear, numb fingers, or cold injuries of feet and hands, and rapid assessment and tourniquet placement and/or other bleeding control measures may have to be performed over/through multiple layers of clothing and body armor. Tourniquet availability on the frontlines is limited and likely to consist of a mish-mash of tourniquet brands and styles. These factors often conspire to create "partial-tourniqueted" patients. Tourniquets may be tightened enough to slow, but not fully stop, bleeding and limb perfusion. Venous and capillary return may be cut off, without halting arterial inflow. 

2) Due to frontline conditions, time of original placement of tourniquets is frequently estimated, or missing altogether.

3) Environmental conditions and threats during evacuation may necessitate rapid movement and rough handling of the patient, which may lead to tourniquet loosening or temporary dislodgement. Poorly made or re-used tourniquets may stretch over time or fail, lead to placement of multiple tourniquets, and intermittent periods of reperfusion or partial reperfusion. 

4) Intentional attempts at tourniquet conversion may be made in the field. Due to fighting conditions, these field attempts may or may not be accurately recorded in the documentation that reaches field hospitals. Patient evacuation routes shift frequently, and patients may pass through multiple patient care teams, comprised of a cast of medical providers that shifts daily.

5) The tourniqueted limb may be subjected to a variety of physiological and environmental conditions, including varying levels of external cooling, varying states of patient blood loss and shock, and varying levels of resuscitative care received.

Due to these variables, Ukrainian doctors cannot rely on hard-and-fast rules such as the 6-hour tourniquet rule. Many tourniquets were placed with good intent, but were never necessary in the first place. Doctors are often forced to decide, based on clinical observations and professional experience, whether tourniquet removal is in the patient's best interest. Does the probability of limb salvage outweigh potential systemic risks to patients? Objective numerical values from blood testing can inform these decisions, if lab services are available. But more often, the critical time for this decision occurs at minimally-equipped forward field treatment points, and thus it must be made based on time of injury, exposure to weather, limb skin color and temperature, injury patterns, and overall patient presentation. 

Here is an interesting case report from Kragh et al, published in Orthopedic Trauma in 2007, which represents the realities of tourniquet placement in conflicts, as well as variability in limb salvage times. The patient, an American helicopter pilot in Afghanistan, was shot in the hand and received RPG shrapnel to one leg. Hemorrhage from the hand was stopped 1 hour after injury by a combination of one purpose-built and one improvised tourniquet. Bleeding recurred 6 hours after injury, and was stopped by tightening the tourniquet. The pilot lay in a snowdrift, with temperatures at -15C, for a half-day after injury. After that, he was insulated by blankets made from cut-out aircraft insulation. Evacuation was delayed due to an ongoing firefight, mountainous terrain, and inclement weather. The patient arrived at a forward surgical facility after 16 hours of continuous tourniquet placement. He had severe soft tissue loss, irreparable radial artery damage, and compartment syndrome. He underwent surgical debridement and irrigation, radial artery ligation, and 3 dorsal + 2 ventral hand fasciotomies, and the operating surgeon deemed hand preservation was questionable. Repeated surgical debridement and irrigation took place over the next month, first at Landstuhl, Germany, then at Walter Reed, before primary wound closure was accomplished. Several more surgeries and physical therapy followed, to correct pain and stiffness. By three years after injury, the patient had recovered sufficiently to use the hand for activities of daily living, and to return to piloting Chinook helicopters.

Nacreous Cloud Pics

More on nacreous clouds and pics taken during Winfly by my trusty little Olympus, which has survived mild freezing 3 times now! (think you'll like this, dad)

As explained during a sunday science lecture by Dr Terry Deschler, atmospheric scientist, nacreous clouds are formed of very small particles like chlorine which refract light very effectively. The angle of refraction is very localized so the brilliant colors in the clouds are constantly changing minute to minute as air currents flow through. Many of these are lenticular clouds- formed by a standing wave of cold air rising up over mountainous terrain. Air must be very cold to form nacreous clouds, so they're generally only seen at very high altitudes over mountains during cold times of the year when there's low-angle sunlight.

The chlorine in the clouds is actually breaking down ozone as we watch- chlorine combines with 03 to form ClO and O2, then ClO interacts further with O3 to form Cl and O2. Thus the chlorine is recycled in the equation and oxygen is formed from the breakdown of ozone.

Atmospheric chlorine comes from natural reservoirs such as acid clouds in the atmosphere. (Interestingly high-flying fighter jets experience etching of glass and metal due to atmospheric acid, and many commercial airliners needed scarred windows replaced in the months after the eruption of Mt Pinatubo released sulfuric acid into the atmosphere). The breakdown of CFCs has added to Earth's natural reservoirs of atmospheric chlorine and resulted in the ozone hole in the Southern Hemisphere. There is actually more chlorine in the skies over equatorial latitudes, but the chemical processes which break down ozone occur at high latitude. Ozone is produced naturally by O2 interacting with the solar winds. Therefore banning of CFCs means eventually the excess chlorine will be naturally cycled out and the ozone layer should reseal, but this will take several generations.

In the meanwhile we enjoy a beautiful pheonomenon with disturbing implications behind it.

TB and the Ukraine War

Not only does the current Russia-Ukraine pose unique risks of regional and global military escalation, it is also creating historic levels of population displacement and military mobilization of convicts, in one of the world's foremost multi-drug-resistant tuberculosis hotspots.

TB, or "consumption" is an ancient disease, closely associated with malnutrition and overcrowding. It is the disease that killed Chekhov, Chopin, Emily Bronte, Orwell, Kafka, Keats, Thoreau, and many others at the height of their creative years.

TB is caused by the bacteria 'Mycobacterium tuberculosis'. Mycobacteria have evolved a waxy coating which allows them to survive and reproduce inside macrophages, thus evading our immune system's first line of defense. Tuberculosis can remain latent within the body for many years, becoming active once the immune system is sufficiently weakened by factors such as malnutrition, diabetes, HIV, or smoking. A patient with latent TB has a 5-10% lifetime chance of developing active TB. Classic symptoms of active pulmonary TB include night sweats, weight loss, and a cough that produces blood-tinged sputum. Untreated, pulmonary TB eventually destroys the lungs in a "swiss cheese" pattern, and leads to patient death. TB bacteria may also disseminate throughout the body, creating a variety of symptoms, such as cutaneous nodules, engorged lymph nodes (scrofula), meningitis, and an array of internal organ problems. 

TB is the world's top infectious disease killer, and fully 1/4 of the world population currently carries latent tuberculosis. Infection rates vary locally, ranging from as low as 3% in some developed countries, to 90%+ in parts of Africa. Only patients with active TB can pass the bacteria on to others, and may infect 15 other individuals per year. Conflict and other social disruption events can have a major impact on spread. Firstly, conflict subjects individuals to physical hardships, such as poor nutrition, inadequate housing, and exposure to other infectious diseases. Second, conflicts displace populations, and lead to overcrowding, poor sanitation, and breakdown of healthcare systems. Studies suggest that war increases annual TB incidence up by up to 20%. The 2022 Russian invasion of Ukraine has resulted in the fastest mass refugee migration since WWII. In 2022, the world-wide number of displaced persons hit a new record of over 100 million souls.

Social disruptions do not have to be conflict-based to facilitate the spread of TB. Russia and other former USSR members have the developed world's highest TB rates, due to social disruptions that occurred during the decade after the fall of the USSR. The 1990's reversed a huge amount of Soviet progress on TB control, which had been achieved via xray detection, isolation, and treatment in sanitariums. Infection rates in Russia fell from 1910 levels of 400/100,000, down to a rate of 17.3/100,000 (in men) and 1.9/100,000 (in women) in 1990. But post-Soviet poverty and healthcare system collapse caused Russian TB rates to double between 1991-1998. During the same time period, incarceration rates tripled in most post-Soviet states. By the late 1990's, TB had become a raging epidemic within the overcrowded Russian prison system, with prisoner infection rates averaging 4,000/100.0000, and in some regions reaching 7,000/100.000.

Mycobacterium tuberculosis's ability to hide from the immune system means that treatment regimes, even for cases that are susceptible to first-line antibiotics, are lengthy. If, due to treatment costs, disruptions in health services, or poor patient education, a patient stops treatment early, evolutionary forces favor the growth of antiobiotic-resistant bacteria within that patient's body. This resistant bacteria can then be passed on to others, garnering new opportunities, with each unsuccessful treatment course, to become resistant to additional medications. The result is multi-drug-resistant TB, or "MDR-TB"- one of today's major public health challenges. Treatment regimes for MDR-TB last up to two years, may cause uncomfortable side effects, and have a significant failure rate. To reduce risk of MDR-TB, DOTS, or Directly Observed Treatment, has become the gold standard for TB treatment worldwide.

However, in post-Soviet states, corruption and economic woes interfered with successful TB programs. Physicians opposed DOTs, feeling that it threatened their already precarious livelihoods. TB medications were re-purposed and sold in markets by crooked pharmacists, or traded for other items by prisoners in treatment programs. Until fairly recently, antibiotics were widely available without prescription at pharmacies in both Russia and Ukraine. It was quite common to self-prescribe an inappropriate course of antibiotics, for example, for a viral cold infection. By 1998 20% of Russian prison cases were MDR-TB. As prisoners were released mid-treatment, this trend spread into the general population. Eastern Europe now accounts for the largest MDR-TB burden in the world. 

In recent years Russia, along with many former Soviet states, has resumed making progress on TB control. Between 2010-2020, Russian TB mortality halved, and general population infection rates fell to 45-50/100,000 (48% MDR-TB). WHO estimated 2021 TB incidence in Ukraine to be 71/100,000 (31% MDR-TB in new cases and 45% in relapse cases). In contrast, average 2021 TB incidence in the EU was 8.4/100,000 (33% MDR-TB). Thus, TB infection in refugee populations moving from Eastern to Western Europe is a major public health concern.

Despite progress within prisons, as well as amongst the general population, TB remains a major problem in Russian prisons. Russia has one the world's highest incarceration rates, with overcrowding and poor living conditions extremely common. A 2017 study estimated that 1 in 10 Russian prisoners have active TB, and that the majority of remaining prisoners have latent infections. A 2019 study found that Russia had the world's second-highest number of new active TB cases amongst prisoners (~13,000 cases, second only to 15,000 cases in Brazil). A 2-3 yr prison sentence leads almost inevitably to TB infection. 48% of Russian prison cases are multi-drug-resistant. Russia also has one of the highest rates in the world of "extensively drug-resistant TB", which is even more difficult to treat than MDR-TB. Russia's heavy reliance on convicts as soldiers, low health standards for enlistment, difficult frontline living conditions, unreliability of medication supplies, potential for injury or capture, and inter-mixing with and displacement of civilian populations all create a major risk for wartime transmission of TB, MDR-TB, and XDR-TB.

In the Ukraine war, post-Soviet health challenges are potentiated by the melange of convict soldiers, frontline conditions, and mass displacement of civilians. The result is a myriad of spread opportunities for the world's new diseases of disruption: MDR-TB, MDR wound infections, and potentially also novel respiratory viruses (think a new wartime COVID variant or a 1918-style influenza). 

Spread of MDR-TB is not the only concern. TB comes in a variety of strains. Interestingly, the prevalent strain in Russia is the "Beijing" type. The Beijing TB strain, first described in 1995, has unique proteins. These potentially make it more infectious and more resistant to treatments. A 2020 literature review of studies involving 7,000 patients found strong support for correlation between the Beijing strain and more unfavorable treatment outcomes. Despite global implementation of DOTS, TB incidence seems to be declining at only 1-2%/yr- far slower than math models predict. The reasons for this include prevalence of HIV coinfection, diabetes, malnutrition, drug resistance, crowding, and poor control infrastructure. Arguably, another reason is the spread of Bejing subtypes- which will also likely be further facilitated by the disruptions of the Ukraine war.     

There is hope on the horizon for TB control. A currently approved vaccine, the BCG TB vaccine, does not prevent TB, but it does serve to lessen risk of some severe forms of disseminated disease in children. Several vaccines designed to prevent pulmonary TB in all ages are currently under development. The most promising is M72. M72 was dropped by its original creator due to low profit potentials, but has recently been picked up by the Gates Foundation and has entered Phase III trials. M72 may be able to prevent pulmonary disease in 54% of infected adults. And for a disease that can take years to treat, and becomes active in 5-10% of patients, who go on to infect 15 other people per year, 54% prevention be a game-changing statistic.
