BackgroundPatients with hepatocellular carcinoma (HCC) often face symptom distress, treatment decision-making, demands for family support, communication needs, and financial concerns during early hospitalization. This study examined factors associated with unmet psychological care needs and developed a risk prediction model, guided by the Neuman Systems Model, to support early nursing stratification.MethodsThis single-center retrospective study included 345 adults with HCC admitted between January 2020 and December 2024. Unmet psychological care needs were defined as a score of ≥3 on any item in the psychological domain of the Chinese Supportive Care Needs Survey Short Form-34 (SCNS-SF34) within 24–48 h after admission. Candidate predictors were classified as intrapersonal, interpersonal, or extrapersonal stressors. After outcome stratification, the cohort was randomly divided into training and validation sets (7:3). Multiple imputation, least absolute shrinkage and selection operator (LASSO) selection across 20 imputed datasets, and multivariable logistic regression were used to develop the nomogram. Discrimination, calibration, decision curve analysis, bootstrap internal validation, and sensitivity analyses were evaluated.ResultsUnmet psychological care needs were identified in 205 patients (59.4%). The final model retained pain numeric rating scale (NRS) score, sleep disturbance, Patient Health Questionnaire-9 (PHQ-9) score, Generalized Anxiety Disorder-7 (GAD-7) score, family support, cooperation in physician-patient communication, and perceived economic burden. Higher pain scores, sleep disturbance, higher depressive and anxiety symptom scores, poor family support, poor cooperation in physician-patient communication, and heavy perceived economic burden were independently associated with unmet psychological care needs. The areas under the receiver operating characteristic curves (AUCs) were 0.851 in the training set and 0.829 in the validation set; the bootstrap-corrected AUC was 0.836. Calibration-in-the-large, calibration slope, Brier scores, and decision curve analysis indicated acceptable apparent and internal-validation performance. Sensitivity analyses excluding PHQ-9 and GAD-7 and applying a stricter outcome definition showed consistent directions of association for the principal predictors.ConclusionsUnmet psychological care needs were common within 24–48 h after admission among patients with HCC. The internally validated nomogram may support early risk stratification, symptom management, psychosocial screening, family involvement, communication optimization, and referral to medical social work services. Independent external validation is required before routine clinical implementation.
The ECHO study: compassion-focused therapy for young voice hearers and their caregivers. A pilot study
BackgroundVoice hearing can occur in healthy people without a trigger, be caused by a traumatic event, or occur as part of a psychiatric disorder. There are still many gaps in our understanding of voice hearing, and research in this field can be challenging, maybe because it is associated with shame and stigma. Those who experience distress by voice hearing could benefit from a treatment, aimed directly at that. The ECHO manualized treatment is based on the principles of compassion-focused therapy (CFT).MethodsTreatment will take place on several different psychiatric hospitals in the Region of Southern Denmark. Treatment consists of a 10-session, manualized CFT for voice hearing. Caregivers participate in half of the sessions, and a recording of the voice content is made, which the caregivers are encouraged to listen to. The study is designed as a prospective single-arm pre–post intervention study using a mirror-image approach, in which participants serve as their own controls over time. The intervention group consists of (N = 60) voice-hearing adolescents aged 13–18 years. Additionally, a clinical comparison group (who also receive the intervention) of (N = 20) individuals aged 18–20 years with first-episode schizophrenia and voice hearing is included for descriptive and exploratory analyses. Data are collected 3 months prior to CFT treatment, immediately before the start of treatment, immediately after treatment is completed, and at 1 month follow-up. Data will be centered around social cognition, perceived social safeness, social connectedness, general well being, auditory hallucinations and compassion.DiscussionThe ECHO study addresses the wellbeing and thriving of an overlooked group of young people. The results of this study will provide information about who the voice hearers are, what challenges they face, and how they perceive them. The results will also provide information about the feasibility and efficacy of the treatment manual and, thus, its potential further implementability. Caregivers participate in half of the sessions, to facilitate a common language about mental states and voice hearing. To support their understanding, a recording of the voice content is made and the caregivers are encouraged to listen to it. We suggest that when caregivers understand the young voice hearers’ experiences, they can adjust their expectations and approach accordingly. We also suggest that by sharing the voice content, the young voice hearer will feel less isolated.Study protocol registrationhttps://clinicaltrials.gov/study/NCT07314515, identifier NCT07314515.

Sperm donors need limits, says a European fertility group
Ties van der Meer doesn’t know how many siblings he has.
The 47-year-old was conceived at a private fertility clinic in the Netherlands using sperm provided by an anonymous donor. After the Netherlands banned anonymous donation in 2004, the doctor who ran the clinic destroyed records that might have identified those donors, he says.
He describes the situation as “problematic.” Children have a right to know their biological parents, he says. While he did ultimately track down one sibling, who helped him identify his father along with other genetic relatives, he may have others he’ll never find.
Other donor-conceived people who have been able to track down siblings have found they have tens or even hundreds of them. One donor-conceived woman who found 25 half-siblings over the course of seven years told the Guardian, “It does make you feel a bit mass-produced.”
We need international limits on the number of children a single donor can contribute to, a European fertility organization argued yesterday. At a conference in London, members laid out plans to start with a Europe-wide limit.
Today many countries, including the UK, have banned anonymous egg and sperm donation. But anonymity can’t be guaranteed even in places where it is technically allowed. Genetic tests offered by companies like Ancestry and 23andMe, along with genetic registries, have made it much easier for donor-conceived people to find parents and siblings who share their genes.
And because sperm can be frozen and stored for years before it is eventually used, the current set-up can result in situations where donor-conceived people discover the identity of a genetic parent only after the person’s death. They might also find that they have siblings of very different ages, all around the world.
Some people are finding hundreds of siblings. Sperm from Jonathan Meijer, a Dutch man who began donating in 2007, was used to conceive between 550 and 600 children. (Stichting Donorkind, a foundation and advocacy group for donor-conceived people that’s chaired by van der Meer, took him to court, and he was ordered to stop donating in 2023.)
Stories like these can be distressing for donor-conceived people. And there are other reasons why limits are considered important. The offspring of a prolific donor might be at risk of unknowingly forming romantic or sexual relationships, for instance. And some people are concerned that a donor with a harmful genetic mutation might pass that down to many children.
This is unlikely, given the level of screening that most donors undergo. But it has happened. A man who donated his sperm to a sperm bank in Denmark was found to have a genetic mutation that significantly increased the risk of multiple cancers. But his sperm had already been used to conceive at least 197 children across Europe. Some of those children developed cancer. Some died.
Many countries already have legal limits for donors. In Malta and Cyprus, for example, both egg and sperm donors are allowed to contribute to the birth of just a single child, according to data presented at the European Society of Human Reproduction and Embryology (ESHRE) meeting in London on July 8.
Other countries set limits based on the number of families a single donor can contribute to, allowing recipients to have children who share a genetic link. In the UK, that limit is set at 10 families per donor.
But these limits are difficult to enforce, partly because donated gametes don’t necessarily stay in their original country. In Denmark, the national limit is set at 12 families. But the country is a major exporter of sperm. In the UK, for example, more than half of sperm donations in 2020 were imported—with most of those coming from either Denmark or the US.
“The only thing that really makes sense is a transnational limit,” Jackson Kirkman-Brown, a professor of reproductive biology at the University of Birmingham, said at the meeting.
Kirkman-Brown and his colleagues have spent months putting together a document that represents ESHRE’s position on these limits. After consulting with fertility specialists, clinics, sperm and egg banks, donors, and donor-conceived people, the team has developed a plan to start with a Europe-wide limit on sperm and egg donations.
ESHRE is calling on sperm and egg banks, as well as fertility clinics, to respect an initial limit of 50 families per donor. That’s still very high, according to a handful of people I spoke to at the meeting. But at least it’s a start.
Europe should move toward setting limits at 15 families per donor, Kirkman-Brown said. “We may find that 15 is also too high,” says Vasanti Jadva, who studies the psychological well-being of people conceived using donated eggs, sperm, and embryos at City St George’s in London. “We still don’t know what the right number is.”
It will be difficult to enforce these limits, too. And if they end up limiting the supply of donor sperm, there’s a chance that some people will turn to unregulated sperm donations from people who do not undergo health screening. Unregulated donations can lead to other problems for prospective parents, including the possibility that donors will seek parental rights over the children conceived using their sperm.
And it will be even harder to establish international limits. When I asked the American Society of Reproductive Medicine for its thoughts on ESHRE’s proposed limits, a representative directed me to a guidance document saying “it has been suggested” that for a population of 800,000, single donors should be limited to “no more than 25 births” in order to avoid the risk that relatives will have children together. (Considering the US has a population of over 340 million, the total figure could be pretty high, but many sperm banks opt to limit the number of families contributed to by a single donor at around 25.)
van der Meer thinks that even a limit of five families from a single donor would be high. International donation makes it even harder for donor-conceived people to connect with genetic relatives, so the limit for international contributions should be set at two families, he says.
Still, he thinks ESHRE’s suggested limit is a “positive first step.” Van der Meer has managed to track down a sibling, his father, and nephews, aunts, and uncles. He hopes that future policies respect the rights of donor-conceived children to know, and be in contact with, their genetic relatives.
“But,” he says, “you have to start somewhere.”

Opinion: The primary care crisis paradox
In March, the Medicare Payment Advisory Commission (MedPAC) released its annual report to Congress on Medicare payment policy. The data related to physician payment are clear: By every metric we track, primary care in America is succeeding, and it has been for years. Nearly all Medicare beneficiaries have a primary care provider (PCP). Over three-quarters can see their PCP within two weeks. Patients in rural environments have less trouble finding a PCP and even shorter wait times. Services and spending on evaluation and management codes are increasing, and compensation among PCPs is rising faster than the rest of the field.
Yet this runs counter to the pervasive narrative that investing more in primary care is the key to solving the American health care crisis.
New York boys club has a time-tested recipe to protect members’ mental health
NEW YORK — A couple of years ago, a reporter approached the Boys’ Club of New York looking to interview some of its middle-schoolers for a story about the mental health crisis in boys.
It’s easy to see why. Many of the about 2,500 boys who participate in the 150-year-old organization’s after-school and weekend activities come from disadvantaged socioeconomic backgrounds, often living in single-parent households or facing the threat of immigration enforcement. With limited access to academic and developmental support, the risk factors are plentiful.
