Addressing Primary Care Needs of Cancer Survivors: The Primary Care Engaged Research for Cancer Survivorship Care (PERCS) Initiative

Primary care clinicians are ideally suited to provide comprehensive, whole-person survivorship care for cancer survivors that focuses on managing co-occurring chronic conditions and mitigating risks related to the cancer and long-term effects of the disease and its treatment. It is therefore critical to develop and test innovative strategies to support primary care practices in delivering high-quality survivorship care. The National Cancer Institute–funded Primary Care Engaged Research for Cancer Survivorship Care (PERCS) initiative encompasses 4 randomized controlled trials funded by…

Breastfeeding Should Not Be a Privilege

In this essay, the author highlights her difficult journey to breastfeed her son, discussing the physical, mental, monetary, and temporal difficulties faced by those who desire to breastfeed and offering recommendations for clinicians and society to make breastfeeding more attainable. Despite knowing breastfeeding can improve outcomes, even the author, a privileged and highly informed obstetrician and gynecologist, nearly could not afford the multiple, varied costs to breastfeed. Breastfeeding should not be a privilege, but an option accessible to all our patients.

Navigating Invisible Complexities in Rural Practice

Working in a rural primary health center in India taught me lessons that medical training never covered. Patients arrived with ordinary complaints, but beneath them were unspoken burdens shaped by gender, belief, poverty, and hierarchy. Over time, I discovered that cultural humility, learning to listen, and reflecting on my own limits became my most reliable tools. Although these experiences unfolded in a remote setting, the lessons hold meaning for clinical practice anywhere. In medicine, healing often begins where diagnosis and treatment end. Sometimes the most radical act is presence…

Where We Learn to Doctor: Rural Practice as Essential Medical Education

Rural medicine is often viewed as a professional compromise, yet it offers some of the most formative clinical training available. It teaches physicians to thrive in discomfort—whether the discomfort is limited medical resources, broad responsibility, geographic isolation, or patients’ economic barriers. That discomfort is what shapes physicians into more resilient, resourceful, and empathetic clinicians. Experiences across rural and remote regions demonstrate how limited access to technology and subspecialists sharpens diagnostic reasoning, strengthens reliance on physical examination, and…

When Routine Care Changes a Life

On a rare day off from my duties as an ophthalmology resident, I wandered into a neighborhood bookstore and was recognized by a woman I had treated for optic neuritis in the emergency department. I didn’t remember her, but she remembered everything. In that gap—between my routine and her life-altering night—I heard what the emergency department often muffles: how ordinary work for me can be extraordinary to the person living it. The piece follows our brief conversation to ask a simple question: how can I carry less and notice more, honoring meaning without slowing the work that must go on?

Death by Rousui in Japan: Rethinking Death, Diagnosis, and Care in an Aging Society

In Japan, death from old age— rousui —is officially recognized on death certificates and is now the third leading cause of death. Rousui describes a gradual decline in physiological function leading to death without a specific underlying disease. As a family physician, my first diagnosis of rousui occurred two decades ago, for a woman in her 90s whose decline was slow, multidimensional, and free of reversible causes. While culturally accepted, rousui remains undefined in clinical terms, creating uncertainty in diagnosis and care. This ambiguity influences end-of-life decision making, sometimes…

Differences in tuberculosis prevalence by sex in low- and middle-income countries over 1993–2025: A systematic review and meta-analysis

by Nicole A. Swartwood, Nanki Singh, Seyed Alireza Mortazavi, Melike Hazal Can, Hening Cui, Do Kyung Ryuk, Peter MacPherson, Katherine C. Horton, Nicolas A. Menzies Background Global and national initiatives to combat tuberculosis (TB) have expanded over recent years. Despite this, the TB burden remains high in some population groups, with men recognized as having elevated TB risks. Summary measures of sex differences in TB prevalence were last estimated in 2016. Since then, many additional prevalence surveys have been conducted, including in the highest TB burden countries. We conducted a…

U = U for all: Advancing equity in HIV prevention

by Thiago S. Torres, Paula M. Luz Suppression of HIV with antiretrovirals eliminates HIV transmission risk, summarized as Undetectable = Untransmittable (U = U). However, U = U literacy remains unevenly understood and shared, and stigmas persist. Equitable and accurate awareness of U = U requires culturally tailored interventions, improved provider education, and supportive policy environments beyond biomedical evidence alone.

Semaglutide-associated risk of nonarteritic anterior ischemic optic neuropathy in patients with type 2 diabetes: A systematic review and meta-analysis of observational studies

by Jędrzej Chrzanowski, Magdalena Walicka, Jacek Burzyński, Małgorzata Zaraś, Arkadiusz Michalak, Wojciech Fendler Background Semaglutide, a glucagon-like peptide-1 receptor agonist, is widely used for the management of type 2 diabetes (T2DM). Recent case reports have raised concerns about a potential association between semaglutide use and the development of nonarteritic anterior ischemic optic neuropathy (NAION), a rare but vision-threatening condition. We aimed to evaluate whether semaglutide use is associated with an increased risk of NAION in patients with T2DM. Methods and findings We…

by Jelisaveta Džigurski, Märt Möls, Kristi Läll, Hannah Currant, Mall Eltermaa, Estonian Biobank Research Team , Reedik Mägi, Lili Milani, Triin Laisk Background Hormonal contraceptives (HCs) are widely used and have well-documented population-level statistics. Previous studies with short follow-ups have focussed on individual HC use and side effects. However, the same aspects over longer periods, HC formulation switching, and the impact of genetic factors on HC side effects remain understudied due to the limited availability of suitable datasets. We investigated whether the Estonian Biobank…

Connected or chained by social media? Child and adolescent mental health in a digital era

by Silja Kosola Social media has evolved from connection to compulsion, disproportionately harming children and adolescents. Addictive designs together with developmental vulnerability fuel mental health risks and highlight the urgent need for stricter age limits and stronger protections. In this Perspective, Silja Kosola outlines how social media disproportionately harms child and adolescent mental health, and argues that while recent policy changes aimed at protecting youth from social media are welcome, stricter age limits and greater accountability of social media companies are needed.
