Flikke, Colonel Julia

.42-3-13: Julia Flikke, Army Nurse Corps, 1st female Colonel in USA - HiPo > .

Flikke (1879-1965) was born in rural Wisconsin, but moved to Chicago following the death of her husband from tuberculosis in 1911. Here she trained at the Augustana Hospital School of Nursing, returning a few years later as assistant superintendent after post-graduate study at Columbia University’s Teachers College in New York.

Flikke enrolled in the Army Nurse Corps in March 1918, and traveled to France where she served as chief nurse. After a short period in the United States after the war, she completed tours of duty in places such as the Philippines and China before spending a number of years at the Walter Reed Hospital in Washington D.C. where she was promoted to the rank of captain and appointed Assistant Superintendent of the Army Nurse Corps.

In 1937 Flikke succeeded the highly respected Julia Stimson as Superintendent, and was promoted to the rank of major. This was the highest rank available to women at the time, although it was much lower than the men who headed up other parts of the Army.

As the advent of the Second World War saw the United States Army expand at a swift pace, Flikke oversaw the growth for the ANC from around 700 nurses in 1940 to tens of thousands by 1943. It was during this period that the government passed Public Law 828, which authorized commissions up to the rank of colonel for Army nurses.

Three months later, on 13 March 1942, Flikke became the first woman in the United States Army to hold the rank of colonel. Although her rating was only temporary, it marked in important step towards the Army-Navy Nurse Act of 1947 that made such appointments permanent.

Julia Otteson Flikke (March 16, 1879 in Viroqua, Wisconsin – February 23, 1965) was an American nurse. Her service to the United States Army Nurse Corps spanned both world wars and included overseas assignments in the Philippines and China. In 1927, she was appointed Assistant Superintendent of the ANC and was promoted to the relative rank of captain. In 1937, she succeeded Julia Stimson as Superintendent with the relative rank of major. She was the last superintendent to hold the office before the statutory limitation of four years was placed on the tenure. She was also the first woman to hold the rank of full colonel in the Army. Although the rating was temporary then (1942), it marked a step forward to granting of full military rank and privileges in 1947. She retired [age 65] due to disability in June 1943.

Julia O. Flikke was born in Viroqua, Wisconsin, on March 16, 1879. She would receive her early education there. Flikke married in 1901, but her husband died ten years later. The following year, she entered the School of Nursing of the Augustana Hospital in Chicago. She graduated in 1915, and, after several months of postgraduate education, Flikke accepted a post as assistant principal of her old school. She would stay there until entering the United States Army Nurse Corps on March 11, 1918, and (after being promoted to chief nurse) serving in Lakewood Township, New Jersey as well as Staten Island. Flick moved to Base Camp No. 11, in France in 1918, serving in several hospitals before returning to the United States in 1919. She first worked at Camp Upton, and subsequently travelled around the country, before setting in Walter Reed General Hospital, where she would work for twelve years.

Vlad the Despoiler


[edited for emphasis] Putin’s Long War Against American Science: A decade of health DISinformation promoted by President Vladimir Putin of Russia has sown wide confusion, hurt major institutions and encouraged the spread of deadly illnesses.

"On Feb. 3, soon after the World Health Organization declared the coronavirus to be a global health emergency, an obscure Twitter account in Moscow began retweeting an American blog. It said the pathogen was a germ weapon designed to incapacitate and kill. The headline called the evidence “irrefutable” even though top scientists had already debunked that claim and declared the novel virus to be natural.

As the pandemic has swept the globe, it has been accompanied by a dangerous surge of false information — an “infodemic,” according to the World Health Organization. Analysts say that President Vladimir V. Putin of Russia has played a principal role in the spread of false information as part of his wider effort to discredit the West and destroy his enemies from within. [DISinformation trolls are running rampant on a recent Washington Post video about hydroxychloroquine and COVID-19. Hell only know how many poorly-educated, anti-authority authoritarian [sic] Americans are credulous enough to believe the LIES.]

The House, the Senate and the nation’s intelligence agencies have typically focused on election meddling in their examinations of Putin’s long campaign. But the repercussions are wider. ... Putin has spread DISinformation on issues of personal health for more than a decade.

His agents have repeatedly planted and spread the idea conspiracy theory that viral epidemics — including flu outbreaks, Ebola and now the coronavirus — were sown by American scientists. The DISinformers have also sought to undermine faith in the safety of vaccines [resulting in the deaths of children], a triumph of public health [destruction] that Putin himself promotes at home.

Moscow’s aim, experts say, is to portray American officials as downplaying the health alarms and thus posing serious threats to public safety."
...
"The Russian president has waged his long campaign by means of open media, secretive trolls and shadowy blogs that regularly cast American health officials as patronizing frauds. Of late, new stealth and sophistication have made his handiwork harder to see, track and fight.

Even so, the State Department recently accused Russia of using thousands of social media accounts to spread coronavirus DISinformation — including a conspiracy theory that the United States engineered the deadly pandemic."
...
"Because public interest in wellness and longevity runs high, health DISinformation can have a disproportionally large social impact. Experts fear that it will foster public cynicism that erodes Washington’s influence as well as the core democratic value of relying on demonstrable facts as a basis for decision-making."

MoH - Ministry of Health, 1919-1968

The recruitment of men to fight in WW1 highlighted the poor health of many of those who enlisted. By the 1910s, public health services were provided through a system of charitable voluntary hospitals and workhouses. Some were administered under the Poor Law through the Local Government Board. In April 1917 Lord Rhondda, President of the Local Government Board, proposed to Lloyd George's Cabinet that a Ministry of Health should take over the functions of the Board and Poor Law administration. The Government's Reconstruction Committee, set up to oversee the rebuilding of the nation after the war, approved of this proposal. Later in the same year in a lecture given at the Royal Institute of Public Health, Major Waldorf Astor MP confirmed the need for one central health department. In 1919 the Government passed an Act which established a Ministry of Health to exercise powers with respect to public health in England and Wales and to promote the health of the people.

The first body which could be called a department of government was the Ministry of Health, created through the Ministry of Health Act 1919, consolidating under a single authority the medical and public health functions of central government. This Act of Parliament established for the first time in the United Kingdom a Minister of Health. It also established the Consultative Council on National Health Insurance, the Consultative Council on Medical and Allied Services, the Consultative Council on Local Health Administration and the Consultative Council on General Health Questions. Separate provision was made for consultative arrangements in Wales and ireland. Christopher Addison was the first minister appointed.

The Ministry of Health, following its creation in 1919, took on the powers and duties of the health functions of the government, which were previously fragmented across departments, most notably from the following:
The principal purpose of the new ministry was to consolidate under a single authority the medical and public health functions of the central government and the co-ordination and supervision of local health services in England and Wales. Revisions to the administration came throughout the 20th century; notably, the co-ordination of local medical services was greatly extended in connection with emergency and wartime services from 1938 to 1945, and these developments culminated in the establishment of the National Health Service (NHS) in 1948. 

In 1968, the Ministry of Health was dissolved and its functions transferred (along with those of the similarly dissolved Ministry of Social Security) to the newly created Department of Health and Social Security (DHSS). In 1988, these functions were split back into two government departments, forming the Department of Social Security (DSS) and the Department of Health.

After the 2018 British cabinet reshuffle, the department was renamed the Department of Health and Social Care.

Until 2017, the department was located in Richmond House, Whitehall

In November 2017, the department's headquarters and ministerial offices were moved to 39 Victoria Street, London. Its other principal offices are Skipton House (Elephant and Castle), Wellington House near Waterloo station and Quarry House in Leeds. Wellington House is now mainly occupied by staff from the department's arms-length bodies. New King's Beam House near Blackfriars Bridge was formerly a Department of Health office prior to the expiry of its lease in October 2011. Alexander Fleming House and Hannibal House were previously used by the department. The archives are at Nelson, Lancashire.

Keynes, Geoffrey - St Bart's

Sir Geoffrey Langdon Keynes (25 March 1887, – 5 July 1982) was an English surgeon and author. He began his career as a medic in World War I, before becoming a doctor at St. Bartholomew's Hospital in London, where he made notable innovations in the fields of blood transfusion and breast cancer surgery. Keynes was also a publishing scholar and bibliographer of English literature and English medical history, focussing primarily on William Blake and William Harvey.

Geoffrey Keynes delayed his medical education in order to serve in World War I, where he served as a Lieutenant in the Royal Army Medical Corps and then worked as a consultant surgeon, becoming an expert in blood transfusion. His experience in the First World War led him to publish Blood Transfusion, the first book on the subject written by a British author. Keynes also founded the London Blood Transfusion Service with P. L. Oliver. Keynes was deeply affected by the brutality and gore that he witnessed in the field, which may have influenced his dislike for radical surgery later in his career.

After returning from World War 1, Keynes began working full-time at St. Bartholomew's Hospital in London, where he worked under George Gask and Sir Thomas Dunhill. Keynes used his influence as an assistant surgeon to advocate for limited surgery instead of the invasive radical mastectomy. Frustrated with the mortality rate and gruesomeness of the radical mastectomy, Keynes experimented by inserting fifty milligrams of radium in a patient's tumor. He later observed that, "The ulcer rapidly healed ... and the whole mass became smaller, softer and less fixed."

Keynes pursued his new idea through a number of trials, observing the effectiveness of injecting radium chloride into breast cancer tumors compared with the effectiveness of the radical mastectomy. The promising results of these trials led Keynes to be cautiously optimistic, writing in 1927 that the "extension of [an] operation beyond a local removal might sometimes be unnecessary." Keynes' outlook was considered a radical break from the medical consensus at the time. Keynes wrote in his autobiography that his work with radium "was regarded with some interest by American surgeons," but that the concept of a limited mastectomy failed to gain significant traction in the medical community at the time. His doubts regarding the radical mastectomy were vindicated some fifty years later, when innovators like Bernard Fisher and others revisited his data and pursued what became known as a lumpectomy. Limited surgeries, like the lumpectomy, accompanied by radiation are now the status quo in breast cancer treatment.

Keynes also a pioneer in the treatment of myasthenia gravis. Much like with breast cancer, the medical community knew very little about how to treat the disease at the time. Keynes pioneered the removal of the Thymus Gland, which is now the norm in treatment of myasthenia gravis.

Keynes enlisted to be a consulting surgeon to the Royal Air Force at the outbreak of World War II. In 1944 he was promoted to the rank of acting air vice-marshal.

Physalis alkekengi - Chinese lantern

Physalis alkekengi (bladder cherry, Chinese lantern, Japanese-lantern, strawberry groundcherry, or winter cherry.

The dried fruit of P. alkekengi is called the golden flower in the Unani system of medicine, and used as a diuretic, antiseptic, liver corrective, and sedative. Like a number of other species in the genus Physalis, it contains a wide variety of physalins. When isolated from the plant, these have antibacterial and leishmanicidal activities in vitro.

Galium aparine, with many common names including cleavers, clivers, goosegrass, catchweed, stickyweed, robin-run-the-hedge, sticky willy, sticky willow, velcro weed, and grip grass, is a herbaceous annual plant of the family Rubiaceae.

Poultices and washes made from cleavers were traditionally used to treat a variety of skin ailments, light wounds and burns. As a pulp, it has been used to relieve poisonous bites and stings. To make a poultice, the entire plant is used, and applied directly to the affected area
https://en.wikipedia.org/wiki/Galium_aparine

Digitalis purpurea (foxglove, common foxglove, purple foxglove or lady's glove) is a species of flowering plant in the genus Digitalis, in the family Plantaginaceae, native and widespread throughout most of temperate Europe. It is also naturalised in parts of North America and some other temperate regions. The plants are well known as the original source of the heart medicine digoxin (also called digitalis or digitalin).

Medicinal plant uses during World War II

By 1941, The Ministry of Health established a Vegetable Drugs Committee at Kew that published guides for herb collectors in the various rural counties. These provided specific instructions about what to collect and how to dry, bundle, and deliver the collections. Hedgerows, the dense natural hedges that define property boundaries, were particularly diverse habitats for both native and naturalized medicinal herbs. Women’s Institutes and Boy Scouts worked locally to provide reliable information on plant identification and collection.

The most essential plants included diuretics (broom, Cytisus scoparius, and foxglove, Digitalis purpurea), vermifuges (male fern, Dryopteris felix-mas), and treatments for gout (autumn crocus, Colchicum autumnale) and influenza (elder, Sambucus nigra).

Among the most important herbs was foxglove (Digitalis purpurea), which was used to regulate heartbeat and save lives in cases of congestive heart failure. Of course, the cardiac glycosides in foxglove degrade if the plants are not handled with care; a pamphlet from Kew advised that collectors spread the plants on drying racks (lace curtains tacked to wooden frames) and then dry the plants in a coke-heated shed at 90-100 degrees Fahrenheit.

Given the sustained attacks against England that began in September 1940, it is not surprising that the Vegetable Drug Committee included valerian (Valeriana officinalis), long valued for its sedative properties, on the list of most essential plants for collection and use.

Collectors also gathered deadly nightshade (Atropa belladonna, the source of belladonna), autumn crocus (Colchicum autumnale, a treatment for gout), and valerian (Valeriana officinalis, a sedative). Other useful plants included wild thyme (Thymus polytrichus, an antiseptic), burdock (Arctium spp., a diuretic), colt’s-foot (Tussilago farfara, a demulcent), and black horehound (Ballota nigra, a treatment for spasms and worm infections). As in World War I, peat moss (Sphagnum spp.) was harvested from bogs to use as an absorbent sterile wound dressing; its naturally acidic pH inhibits bacterial growth and helps to prevent infection.

Vitamins were another wartime necessity; most of these metabolic compounds were discovered between 1920 and 1941, and they remained in the forefront of medical concern. Because home front shipments of citrus fruits were increasingly rare, research at Kew centered on rosehips as a rich source of vitamin C. Botanically speaking, a rosehip is the cup-shaped hypanthium that remains behind after a pollinated rose drops it petals. These are often red-pigmented, and they contain the small, seed-like fruit (achenes), which are dispersed by birds feeding on the hips.

For instance, various mints and tansy (all collected and used medicinally in England during the war) are antibiotic to pathogenic strains including Streptococcus and Staphylococcus. Why? The medicinal secondary compounds of plants often function against bacterial and fungal attack—especially in plant roots, where compounds tend to concentrate. I often wonder that if we continue to overuse antibiotics and antiseptics, we will again need medicinal herbs as pharmaceuticals—this time for their antibiotic properties.

NEOPRENE & NYLON
In 1931, DuPont started to manufacture neoprene, a synthetic rubber created by Carothers' lab. The research team then turned their efforts towards a synthetic fiber that could replace silk. Japan was the United States' main source of silk, and trade relations between the two countries were breaking apart.


By 1934, Wallace Carothers had made significant steps toward creating a synthetic silk by combining the chemicals amine, hexamethylene diamine and adipic acid to create a new fiber formed by the polymerizing process and known as a condensation reaction. In a condensation reaction, individual molecules join with water as a byproduct.

Wallace Carothers refined the process (since the water produced by the reaction was dripping back into the mixture and weakening the fibers) by adjusting the equipment so that the water was distilled and removed from the process making for stronger fibers.

A-Tish-Oo! (1941-2)

1941 A Tish Oo! > .
Better quality (without irritating tabs) - Internet Archive > .

A [February] 1941 British film about how coughs and sneezes spread diseases. Some masks that can be worn to help stop the spread of diseases are shown. Produced by Verity Films for the Ministry of Information.

Why Londoners in the blitz accepted face masks to prevent infection – unlike today’s objectors ojectionables .

"For the countless Londoners driven into communal shelters by nightly German air raids, personal space had become a luxury. This was particularly so for those who sought shelter in the London underground. For its perceived subterranean safety, by the blitz’s peak, some 150,000 citizens were sleeping in tube stations.

Though the dangers of close personal contact were not the only thing on the minds of concerned public health officials, preventing epidemic disease in the overcrowded spaces of the tube stations was a major concern. The mask emerged as a common-sense solution to the problem of thousands of shelterers suddenly using the tube’s damp, poorly ventilated spaces as their nightly abodes.

Eager to prevent an epidemic before it started, the Ministry of Health set up an advisory committee to investigate conditions in air-raid shelters, with special reference to health and hygiene. The official call for masks came in December 1940, two months into the blitz and just as flu season was getting underway, in a white paper that recommended their use alongside a raft of other preventive health measures. British scientists conscripted to the Medical Research Council’s Air Hygiene Unit were convinced: the “principle of wearing masks for protection against droplet infection” was a sound practice.

The Ministry of Health endorsed three types of mask: the standard gauze type (similar to today’s homemade masks); a cellophane screen (like today’s visors, but only covering the mouth and nose); and the commercially available “yashmak” (in the style of the Muslim veil), for the “fashion conscious”. The ministry ordered 500,000 masks to be distributed as needed in the event of an epidemic and commissioned an instructional leaflet for shelterers.

British newspapers publicised the government’s new policy. On February 5 1941, the Times reported that Sir William Jameson, the chief medical officer, had endorsed the new masks, and, more colourfully, Ritchie Calder, a journalist for the Daily Herald tried one out in public. “After ten minutes yesterday my anti-flu ‘windscreen’ ceased to be a source of ribald remarks,” he reported. “People round me became used to seeing me working in what looked like a transparent eye-shade which had slipped down my nose.”

Predicting that masks would become “as commonplace as horn-rim glasses”, Calder wrote that he could even blow his nose with his mask on. The only thing he couldn’t do “in comfort”, he reported, was “have a cigarette”.
Sharp contrast

A short propaganda film commissioned by the Ministry of Information and released in February 1941 also saw the mask message as self-evidently good sense. “If the shelter doctor or nurse gives you a mask,” the narrator exhorted, “well, wear it!”
.....
Despite protests to the contrary, the source of the COVID-19 mask controversy is not rooted in longstanding concerns about individual rights or British character. We need to look elsewhere to find its source: to the general breakdown in communication and trust between experts, the government and [wrong-wing] members of the public, that became a mainstay of contemporary life well after the blitz had passed and has been exacerbated by the pandemic."
