Summary:

This short but complex book assesses the many, current risks to all life on earth and considers some avenues for repair that may provide hope for the future. E. O. Wilson, a distinguished scientist, describes how all life on earth is inter-related. With a long view to the past and a wide view of the present—from microscopic creatures to humans—Wilson praises our planet’s biodiversity and warns of the dangers that may cause it to collapse; these dangers are human-related. Humans are an apex predator, smarter than all other creatures, but we are also too numerous, using too many resources, and causing various pollutions, including global warming. The health of the world and the health of all its creatures—humans included— are, for better or worse, interlinked forever.   
A Prologue warns that we are playing an “end-game” with the earth. To avoid a point of no return from mass extinctions, Wilson proposes a bold plan of setting aside one-half of the earth in reserve in order to stabilize the survival of humans.  

Part I, “The Problem,” describes the damage to our planet, on a par with the Yucatan asteroid 65 millions years ago, the so-called Fifth Extinction. We live in a narrow biosphere threatened by dying species, invasive species, collapse of interdependency, pollution of air, land, and water, loss of the commons, overhunting, human population growth, and outright habitat destruction (including the many impacts of climate change). He states, “the Sixth Extinction is under way” and “human activity is its driving force” (p. 55).   

Average time for recovery from each of the five previous extinctions is 10 million years. 

Self-centered humans do not understand the vast complexity of nature, including the many species not yet studied. He imagines far-distant geologists observing, “What a terrible time it was for people, and for the rest of life” (p. 9).  

Part II, “The Real Living World,” criticizes some conservationists who see nature in service to humans. Wilson says we are not owners of nature but stewards. He describes the abundant life of the Great Smoky Mountains National Park and a typical seashore as well as the extinction of the Ivory-Billed Woodpecker. Wilson contacted “eighteen of the world’s senior naturalists,” asking for suggestions for the “best reserves” to shelter “plants, animals, and microorganisms” (p. 135). Fifteen pages lovingly describe their recommendations of 33 places around the world. He concludes that “a great deal of Earth’s biodiversity can still be saved!” (p. 136).  

Part III, “The Solution” states, “The only solution to the Sixth Extinction is to increase the area of inviolable natural reserves to half the surface of the Earth or greater” (p. 167). Wilson reviews crises of water and food, and he warns against “self-inflicted disaster” that could wipe out most species by the end of this century. He provides two examples of restoration projects, the long-leaf pine lands in Florida and Gorongosa National Park in Mozambique. He believes the population bulge to ten billion people will be temporary.            

Wilson rejects geo-engineering of the oceans or the atmosphere as well as a proposed use of a passing asteroid. He argues that synthetic biology has promise for improving our brains for moral reasoning and ecological understanding. We need altruism (all working for all) and biophilia (deep love of nature).

In 1942, Beth Pierce was completing her internship in the new discipline of occupational therapy in a Baltimore hospital where she meets Jim, a conscientious objector who is training to become a medic. They share a love of poetry and the arts. He goes off to war and serves in the foxholes and trenches of the dreadful conditions at the front. She stays in North America serving in rehabilitation with the war wounded – young men damaged physically and mentally from the great trauma. Until 1945, they exchange a remarkable series of letters that describe the war, their parallel work with the war wounded, their hopes for the future, and gratitude for each other’s thoughts. The letters always close with “Please write.”

Summary:

The aim of these reflections on uncertainty in medicine is not to discredit evidence-based medicine or to incite suspicion of the careful and caring processes by which most clinicians arrive at the advice they give.  Rather it is to change conversations among practitioners and between them and their patients in such a way as to raise everyone’s tolerance for the inevitable ambiguities and uncertainties we live with.  If the public were more aware of the basic rules of mathematical probabilities, how statisticians understand the term “significance,” and of how much changes when one new variable is taken into account—when a new medication with multiple possible side-effects is added to the mix, for instance—they might, Hatch argues, be less inclined to insist on specific predictions.  He goes on to suggest that there is something to be gained from the challenge of living without the solid ground of assurances.  When we recognize the need to make decisions with incomplete information (a condition that seems, after all, to be our common lot) we may refocus on the moment we’re in and see its peculiar possibilities. Changing the conversation requires a critical look at medical education which, Hatch observes, “measures a certain type of knowledge essential to medical practice, but it consequently engenders a conception of medicine best described as overly certain . . . .”

Summary:

In this volume, Gonzalez-Crussi trains his sights on medical history, applying his lyrical writing skills to essays that he hopes will help preserve the humanistic core of the medical profession. Because of its brevity (250 pages), he apologizes for its focus on "Western medicine since the inception of the scientific method"(p.xi), but does note that he acknowledges "the continuity between ancient and modern medicine...[and] the contributions of the Orient, and of epochs predating the dominance of the rational spirit" (p.xi).What distinguishes this volume beyond the writing is the thematic organization. It begins with the Rise of Anatomy and Surgery, but then moves to Vitalism and Mechanism, The Mystery of Procreation,  and Pestilence and Mankind, before finishing with a look at Concepts of Disease, The Diagnostic Process and Therapy (including a brief focus on psychiatry). In the last section, Some Concluding Thoughts, Gonzalez-Crussi returns to his motivations for writing this short history, citing the mixed blessings of scientific progress whose gains, for example, are offset by those who "appear to try to 'medicalize' every aspect of human life" (p.210).

Summary:

This is the third book in a series on the history of medicine and medical education by Kenneth M. Ludmerer, a practicing physician and historian of medicine at Washington University of St. Louis. The first, Learning to Heal: The Development of American Medical Education, published in 1985, dealt with the history of medical schools and medical education in the US from their origins in the 19th century to the late 20th century. In 1999 he published Time to Heal: Medical Education from 1900 to the Era of Managed Care. This book, Let Me Heal: The Opportunity to Preserve Excellence in American Medicine, published in 2015, is a sweeping history of graduate medical education in the United States from its inception to the current day.

In 13 chapters and 431 pages (334 pages of text, 97 of reference and index), Ludmerer traces the residency from early apprenticeship days to its metamorphosis (at Johns Hopkins, of which he is a justly proud medical school alumnus) into the embryonic form of what we now call an internship and residency. Giants like “The Four Doctors” (to use the title of John Singer Sargent’s famous portrait of William S. Halsted, William Osler, Howard A. Kelly and William H. Welch - but known simply as “The Big Four” at Hopkins) were the godfathers of the American postgraduate medical model which emphasized clinical science, teaching, patient care and research. The rise of acute care teaching hospitals as the venue of postgraduate medical education, and not the medical school or university, is an interesting story and one which Ludmerer tells in great detail over a number of chapters. It is one replete with predictable turf wars, professional turmoil and politics, and societal change in all aspects of the 20th century. This last phenomenon receives its due attention in every chapter but is dissected in meticulous detail in the final chapters dealing with the Libby Zion case, duty hours and the increasing role of the Accreditation Council for Graduate Medical Education (ACGME) in postgraduate medical education.

Beginning in the 1930’s, American medicine grew increasingly specialized and, in the ensuing decades, subspecialized, much to the consternation of pre-WW II general practitioners who, suddenly and for the first time, found themselves in the minority, in numbers and in influence, of their own profession. Concomitant with the phenomenon of specialization was the imprimatur by academic medicine of the structured, sanctioned residency as the sole route to specialty practice with, of course, the birth of associated accrediting agencies. Along with the move, physically, academically and politically, of postgraduate medical education to acute care teaching hospitals, the control of this education moved from medical schools to the profession at large.

Ludmerer deftly describes the “era of abundance”, the salad days of postgraduate medical education in the 1950’s and 1960’s when giants still made rounds on the floors of postgraduate medical venues; funds were plentiful; outside criticism was an as yet unborn bête noir; and social, economic and governmental curbs were only a tiny distant cloud in an otherwise blue sky. Ludmerer is correct in attributing much of medicine’s professional and social hegemony as well as its transient immunity to criticism in this era to the following evident successes of medicine: antibiotics; initial inroads into antineoplastic therapies; startling technological innovations in imaging; a burgeoning spate of life-saving vaccines; and spectacular advances in surgery, especially pediatric, cardiothoracic and transplant. Fatal diseases of the 1930’s and 1940’s were now often cured in days and of historical interest only.

Like all salad days, those of medicine eventually succumbed to new historical forces: foreign medical graduates in the workplace; the ever-growing financial burden of the residency; and economic pressures like Medicare and its associated regulation. There were other factors, too: professional and societal expectations of standardization and quality care; the explosion in subspecialties; the horrid wastefulness of unnecessary diagnostic tests and therapies borne of an earlier undisciplined abundance; the supercession of the intimate primary physician-patient relationship by the fragmented care of specialists and the rising supremacy of technology over personalized histories and careful physical examinations (why percuss the abdomen when you can get a CAT scan?). Dissatisfaction amongst residents is a dominant theme Ludmerer rightly raises early and often: the conflict and tension between education and service, between reasonable work and “scut”, between being a student and a worker (at times, quite a lowly one).

”High throughput” - the much more rapid turnaround time between admission to an hospital and discharge - has radically changed forever the entire nature of postgraduate medical education, and not for the better in the eyes of the author and of this reviewer, who were fellow residents a lifetime ago at Washington University in St. Louis. This decreased length of stay, a result of the remarkable improvements in diagnosis and therapy mentioned above, meant that the working life of providers (attending physicians, residents, physician assistants and nurses) was in high gear from admission to discharge, thereby increasing tension, likelihood for error and, exponentially, the workload for the resident while simultaneously and irrevocably damaging the possibility of a meaningful, careful provider-patient relationship (like a friendship, of which it is a subspecies, such relationships can not be rushed) and decreasing opportunities for learning. Medicare; changing patient populations; societal and professional disgruntlement; the Libby Zion mess and the ensuing cascade of regulations from all sides, but most especially the ACGME - all receive careful and systematic treatment in the final chapters of this monograph.

Ludmerer ends with a chapter listing what he sees as opportunities for achieving (or re-achieving) excellence. Indeed, he has made it the book’s subtitle. They are the following: a plea for the ACGME to revise its 2011 duty-hour regulations; an equally earnest hope that interns and residents will soon realize a more manageable patient load; a related wish for academic medicine to decrease the unfortunate occurrence of economic exploitation of house officers; a suggestion that this annotator shares, i.e., that the process of supervision, improved (but inadequately) with recent ACGME requirements, be further strengthened; and a hope that medical schools will restore teaching to the central place in the institutional value system it used to enjoy. Ludmerer issues a call for the more vigorous promotion of “an agenda of safety and quality in patient care” (page 312) and suggests that the education of residents be expanded to include venues outside in-patient sites. Elsewhere in the book, he also expresses the expectation that the inclusion into clinical teaching of private patients alongside “ward” patients, more feasible with recent improvements in the re-imbursement of medical care, be routine and maximized to the enjoyment and benefit of all concerned.

Summary:

Jonathan Franzen tells the story of his father’s slow and inexorable decline from Alzheimer’s disease. His story is a familiar one, and one that millions of people can now tell: at first the initial odd behaviors and memory failures attributed to various causes other than dementia, then the diagnosis and medical interventions to stem the inevitable, and finally the inevitable. While Franzen also describes the toll his father’s dementia exacts on the immediate family—as well as some truths it uncovers about his parents’ marriage—he does not put a significant emphasis on family effects.  

Interwoven in Franzen’s recounting of his father’s plight are a few digressions on Alzheimer’s disease. In one he wonders, as many others have, about whether Alzheimer’s disease is more a medicalization of certain behaviors than the result of brain pathology, or otherwise just “ordinary mental illness being trendily misdiagnosed as Alzheimer’s.” (p. 19) In others, he briefly summarizes the well-known theory involving plaques and neurofibril tangles as a cause of Alzheimer’s, and thoughts on how memories form and work in the brain. In yet one other digression, Franzen reminds us that Alzheimer’s disease as originally described in 1906 was a rare type of dementia characterized by early onset in middle age and rapid progression. He further notes that it was not until the latter part of the 20th century when Alzheimer’s disease was tagged as the fifth leading cause of death and the disease of the century, and only through the efforts of a coalition comprising clinical scientists, politicians, and patient advocates.

Summary:

This memoir of a life in medicine takes the writer from St. Louis to a Navajo reservation to Central America to the east coast and from urban hospitals to ill-equipped rural clinics. It offers a wide range of reflections on encounters with patients that widen and deepen his sense of calling and  understanding of what it means to do healing work.  He learns to listen to tribal elders, to what children communicate without words, to worried parents, and to his own intuition while calling on all the skills he acquired in a rigorous medical education.  Always drawn to writing, Volck takes his writing work (and play) as seriously as his medical practice, and muses on the role of writing in the medical life as he goes along.

Summary:

Paul Kalanithi, diagnosed with stage IV metastatic lung cancer when he was a neurosurgery resident at Stanford University, was faced with a decision. Should he truncate his career in neurosurgery in order to become a writer - a career he had always envisioned for himself after completing a couple of decades of neurosurgery practice? Married to Lucy Kalanithi, an internist he had met in medical school, Paul’s career and future had looked bright and promising. But as he entered his final year of a seven-year residency, symptoms of excruciating back pain and significant weight loss began. Garbed in a hospital gown, he examines his own CT scan – this is how we meet Paul at the beginning of the Prologue. He then writes of the relatively brief period of misdiagnosis prior to the CT scan. With the initial negative plain x-rays, he is started on nonsteroidal anti-inflammatory drugs. But breakthrough pain and continued weight loss leads to the CT. Paul the physician understands the death sentence the images portend; Paul the patient is just beginning his journey. The diagnosis and treatment cause him to reassess his decisions about his life, to decide to father a child even though he knows he will never see the child grow up, and ultimately to write a memoir, essentially for his daughter.

Paul had graduated from Stanford with undergraduate and master’s degrees which reflected his dual love of literature and science. He combined these in a second master’s degree from Cambridge University in the history and philosophy of science and medicine before attending Yale for his medical degree. He and his wife return to California for residencies. The book is largely a blend of his dual interests: a deep and abiding love and faith in literature and how words can reveal truths, and a passion for the practice and science of neurosurgery. The rupture of fatal illness into his life interrupts his dogged trajectory towards an academic medical career, and, like all ruptures, confounds expectations and reorients priorities.

The book has five parts: a foreword by physician-writer Abraham Verghese, who notes the stunning prose Paul produced for an initial article in The New York Times and exhorts the reader to “Listen to Paul” (page xix); a brief prologue; two parts by Paul Kalanithi (Part I: In Perfect Health I Begin, and Part II: Cease Not till Death); and a stunning, heart-breaking epilogue by Lucy Kalanithi. In the epilogue, written with as many literary references and allusions as her husband’s writing includes, Lucy provides the reader with a gentle and loving portrait of her husband in his final days, reaffirms his joy in their daughter Cady, and chronicles how she kept her promise to her dying husband to shepherd his manuscript into print.

The bulk of the book is memoir – a childhood in Arizona and an aversion to pursuing a life in medicine due to his hard-working cardiologist-father, experiences at Stanford which eventually led him to reverse his decision to avoid a medical career, the stages of his medical career and caring for patients, and his devastating cancer. Though initially responsive to treatment—and indeed, the treatment enables him to complete his residency and decide to father a child with Lucy—the cancer is, as prognosticated from the diagnosis, fatal.

What makes this memoir so much more than an exercise in memory and a tribute to the herculean effort to write while sapped by cancer and its treatment, are the philosophical turns, the clear love of words and literature, and the poignancy of the writing. He begins reading fiction and nonfiction again: “I was searching for a vocabulary with which to make sense of death, to find a way to begin defining myself and inching forward again. The privilege of direct experience had led me away from literary and academic work, yet now I felt that to understand my own direct experiences, I would have to translate them back into language…I needed words to go forward.” (pp 148-9) Paul’s writing ends with what is arguably some of the most poetic prose ever written. He concludes by speaking directly to his infant daughter: “When you come to one of the many moments in life where you must give an account of yourself, provide a ledger of what you have been, and done, and meant to the world, do not, I pray, discount that you filled a dying man’s days with a sated joy, a joy unknown to me in all my prior years, a joy that does not hunger for more and more but rests, satisfied. In this time, right now, that is an enormous thing.” (p. 199)
