Anyone ever done a 'community project bingo card'? Don't think people have any idea how broken the system is and how much social work type stuff small, poorly funded local organisations like us have to do. This week I have spent hours talking with hospital, police, post office and train station staff, council, housing team, GP surgery to track down a missing person and get them the help they need. Hopefully all sorted now .. absolutely none of this is my job but we have the local connections to do it. For those of you wondering where social services fits in, I could not get hold of social services at all.. was on hold for an hour and gave up. Please vote to get #ToriesOut on Thursday! #BrokenSystem#ToriesOutNow#CommunitySupport#ge2024uk#election2024
If you are able to financially afford to donate to good causes.. please look around and see who is doing community work in your area. I guarantee all of them are doing similar #SocialWork#Crisis stuff to us and struggling with funding. One-off or monthly #donations via online sites will all include #GiftAid if donors are UK tax payers so your money goes a lot further and regular income is hugely important for all of us. Here is our page on #LocalGiving but if you are donating on any of these.. watch out..most of these sites add an 'optional' fee which you can change to 0 if you want! #MutualAid#MutualAidRequesthttps://localgiving.org/charity/settlecommunityandbusinesshub
Hepatitis C is a global public health threat, affecting 56 million people worldwide. The World Health Organization has committed to eliminating hepatitis C by 2030. Although new treatments have revolutionised the treatment and care of people with hepatitis C, treatment uptake has slowed in recent years, drawing attention to the need for innovative approaches to reach elimination targets. One approach involves using existing notifiable disease data to contact people previously diagnosed with hepatitis C. Within these disease surveillance systems, however, competing tensions exist, including protecting individual rights to privacy and autonomy, and broader public health goals. We explore these issues using hepatitis C and Australia’s legislative and regulatory frameworks as a case study. We examine emerging uses of notification data to contact people not yet treated, and describe some of the ethical dilemmas associated with the use and non-use of this data and the protections that exist to preserve individual rights and public health. We reveal weaknesses in rights protections and processes under Australian public health and human rights legislation and argue for consultation with and involvement of affected communities in policy and intervention design before notification data is used to increase hepatitis C treatment coverage.
The post The Application of Australian Rights Protections to the Use of Hepatitis C Notification Data to Engage People ‘Lost to Follow Up’ was curated by information for practice.

A recent study has unveiled new insights into the neural mechanisms underlying treatment-resistant depression. By recording stereotactic electroencephalography signals (sEEG) from patients’ brains, the team identified specific abnormalities in how depressed individual process emotional information. This study, published in Nature Mental Health, provides a promising step towards understanding and potentially treating this challenging condition.
Depression is a common but serious mental health disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. It affects millions of people worldwide and can significantly impair one’s ability to function at work, school, and in personal relationships.
While many individuals with depression respond well to standard treatments, such as medication and psychotherapy, a significant subset of patients do not experience sufficient relief from these approaches. This condition is known as treatment-resistant depression. It is defined as the failure to respond to at least two different antidepressant treatments administered at adequate doses and durations.
The new study conducted by the researchers at Baylor College of Medicine aimed to explore the neural basis of an emotion-processing bias observed in individuals with depression. This bias leads to a stronger response to negative information compared to positive information, which exacerbates depressive symptoms. Understanding the neural mechanisms behind this bias is crucial for developing targeted interventions that can better address the unique challenges of treatment-resistant depression.
“There has been a big question in the field about whether there was a physiological abnormality we could measure related to depression, as people had historically thought of it as a disorder of the ‘mind’ rather than one of the ‘brain’ and its cells. In this study, we were able to capture very sensitive data from awake, behaving human subjects that demonstrate a physiological basis for treatment-resistant depression,” said study authors Kelly Bijanki, an associate professor, and Xiaoxu Fan, a postdoctoral fellow.
For the study, sEEG electrodes were implanted in specific regions of the participants’ brains, particularly the amygdala and prefrontal cortex (PFC). These regions were chosen due to their known roles in emotion processing and regulation. The electrodes provided high spatial and temporal resolution recordings of brain activity, allowing the researchers to observe detailed neural responses to emotional stimuli.
The study included 12 epilepsy patients and 5 patients diagnosed with treatment-resistant depression. The epilepsy patients served as a control group since they were already undergoing stereotactic electroencephalography (sEEG) monitoring for seizure localization. The treatment-resistant depression patients had not responded to at least four different antidepressant treatments and were recruited as part of an early feasibility trial.
Participants were asked to rate the emotional intensity of human face photographs displaying various expressions, ranging from very sad to very happy. This task was designed to evoke and measure their neural responses to both positive and negative emotional stimuli. The emotional intensity ratings were recorded using a computer interface, ensuring precise synchronization with the brain activity data captured by the sEEG electrodes.
The researchers found that individuals with treatment-resistant depression exhibited a heightened and prolonged response in the amygdala when viewing sad faces compared to the control group. This increased activity began around 300 milliseconds after the sad faces were presented, indicating an overactive bottom-up processing system.
The treatment-resistant depression group also showed a reduced amygdala response to happy faces at a later stage (around 600 milliseconds). This finding suggests a diminished ability to process positive emotional stimuli, which may play a role in the persistent low mood characteristic of depression.
The researchers observed increased alpha-band power in the prefrontal cortex of the treatment-resistant depression patients during the late stage of processing happy faces. Alpha-band power is thought to reflect inhibitory processes in the brain.
Additionally, there was enhanced alpha-band synchrony between the prefrontal cortex and the amygdala, indicating stronger top-down regulation of the amygdala by the prefrontal cortex in these patients. This suggests that the prefrontal cortex may excessively inhibit the amygdala, contributing to the reduced emotional response to positive stimuli.
“sEEG can provide data with high temporal resolution and reliable anatomical precision of signal sources,” Bijanki and Fan told PsyPost. “With the help of sEEG, our results clearly revealed that different neural mechanisms are responsible for the biased negative and positive emotion processing in TRD patients.
The study also explored the effects of deep brain stimulation on neural responses in treatment-resistant depression patients. After deep brain stimulation was administered to the subcallosal cingulate and ventral capsule/ventral striatum regions, the neural responses to emotional stimuli in the patients showed significant changes.
The amygdala response to both sad and happy faces increased, and the alpha-band power in the prefrontal cortex decreased during happy-face processing. Furthermore, the alpha-band synchrony between the prefrontal cortex and the amygdala during happy-face processing was reduced, bringing the neural activity patterns closer to those observed in the control group.
“Treatment-resistant depression has a signature in the firing pattern of neurons in the brain, especially during an emotional task,” Bijanki and Fan explained. “We see the brain being perhaps overly sensitive to negative emotional information in depression patients, and we see evidence of increased top-down inhibition from a moderating brain region that may explain the abnormality. Further, we see after therapeutic brain stimulation, this pattern is normalized. We hope with further study this signal may help clarify the mechanism of depression and suggest new potential treatments.”
The small sample size limits the ability to generalize the findings. Additionally, using epilepsy patients as controls, who may have varying levels of depressive symptoms themselves, might affect the comparison. Future research should aim to include larger and more diverse samples to validate these findings.
The researchers also plan to explore how these neural markers can be used to evaluate the effectiveness of depression treatments. “We hope to use the biased emotional processing signature as a biomarker to evaluate the effects of depression treatments and as an indicator of the severity of depression symptoms in future patients,” the researchers said.

I don't think most people realise how much unofficial #SocialWork type stuff all #community projects end up doing these days. Rural services are dire or non existent, the job centre hounds everyone and woe betide you if you can't use internet to update your universal credit journal. I'm about to take food and drink supplies to a local rough sleeper who lives under a bridge. He is being told he must go to the job centre (a mere 16 miles away) in spite of having a sick note saying he has suspected advanced cancer and is really unwell. It will be me or one of our volunteers taking him to Job Centre and also to hospital (25 miles away) for a scan on Friday if he is willing to go. Sigh..
