Vaping linked to serious lung disease

A new study has found vaping more than doubles the risk of serious lung disease.
A longitudinal study published by Oxford University has found people who vape, even without a history of smoking, are 2.29 times as likely to develop chronic obstructive pulmonary disease (COPD).
Respiratory physician Dr Stuart Jones said it was one of the first studies to truly spell out the long term risks of vaping.
"The important part with this is, with a lot of the previous studies a lot of the vape users had been previous smokers and the data wasn't so clear, whereas in this study the vapers had only ever been vapers," he said.
"So this is the first major study to show quite clearly that vaping alone causes COPD."
Other studies have found smokers are three to five times as likely to develop COPD, meaning vaping remained a safer alternative to smoking.
"The rate of COPD diagnosis was higher in people who were smoking than vaping, so it's still not as risky ... but there's clear long-term negative effects," Dr Jones said.
But the most significant finding was that dual users of cigarettes and vapes had a higher risk than even those who exclusively smoked cigarettes.
"The biggest problem is in people who choose to dual use, so in other words they're smoking and vaping ... they had the highest risk of all, and it's because smoking and vaping damage the airway in slightly different ways, so if you combine the two you double up," he said.
"I think the message is simple: If you don't smoke, don't start vaping. If you're vaping, don't keep smoking."

‘Long overdue' unpaid holiday pay processed
A nine-year wait for more than $40 million in unpaid holiday pay for Te Whatu Ora Health New Zealand southern district staff is over. Yesterday, about $41 million in Holidays Act remediation payments were processed for 5900 current southern district staff. HNZ Te Waipounamu regional deputy chief executive Martin Keogh acknowledged it had been a drawn-out process. Martin Keogh. PHOTO: ODT FILES "We have made significant progress in the remediation project with around two-thirds of our current Health New Zealand employees now having received the money they are owed. "I want to acknowledge the patience of our staff who have been waiting for their payment and also recognise the huge work from our payroll teams, both nationally and in the regions, who have worked tirelessly on this programme." New Zealand Nurses' Organisation (NZNO) president Anne Daniels was pleased the wait was over. "NZNO acknowledges the Holidays Act remediation payment to its Te Whatu Ora southern members, but it has been long overdue. "These are payments owed to nurses since 2016. "Payments have been budgeted for by the government and there is a payment schedule in place." The issue has become protracted — at least seven other health districts (Tairāwhiti, Waikato, Canterbury/West Coast, Whanganui, Mid Central, Bay of Plenty and Lakes) are yet to be sorted. The payment meant over 75% of payrolls nationally had been rectified, Mr Keogh said. Anne Daniels. PHOTO: ODT FILES "This means those payrolls are now compliant with the Act and staff are being paid correctly for their holidays in a nationally consistent way. "Nationally we have about 90,000 current employees plus 130,000 former employees covered by the Holidays Act remediation project, for the period from May 1, 2010, to the present day." Southern district is the s 17th payroll nationally to have Holidays Act remediation payments processed to current staff, with Auckland, Counties Manukau, Waitematā, Taranaki, Wairarapa, Nelson Marlborough, Hutt Valley, Capital Coast and four former shared services completed, and a partial payment made in Bay of Plenty, Te Tai Tokerau, Hawke's Bay and South Canterbury. The payment to southern district staff takes the total amount paid so far nationally to over $491.1m across 65,562 current employees, Ms Daniels said. "Nurses have been frustrated by the years-long delays in getting paid what they are owed. "Paying staff correctly for the work they perform is a minimum expectation of any employer. "NZNO continues to work on issues with Te Whatu Ora such as how to ensure members who work in multiple roles receive their correct entitlement."

Study reveals ‘rich tapestry' of cultures
Unlocking the first ancient genomes (aDNA) from Papua New Guinea and the Bismarck Archipelago has allowed Otago scientists to take a significant step forward in understanding the genetic diversity of the nation and those in the wider Pacific. It has helped bring clarity to the great migration of early Pacific pioneers, considered to be ancestors of many Pacific people, including Māori. Monica Tromp. PHOTO: ODT FILES Research co-author and University of Otago Southern Pacific Archaeological Research project manager Dr Monica Tromp said aDNA acted like "a time machine", revealing how people lived and interacted thousands of years ago, and how those connections still influence our world. By combining aDNA with dietary evidence and linguistics, the study revealed how the pre-colonial coastal communities were surprisingly genetically diverse from each other, and suggested many cultural groups did not intermarry for some time. The research revealed "Pacific Island cultures were far more diverse and complex than we ever imagined". "Rather than being one unified group, these ancient communities represented a rich tapestry of different cultures and peoples." New Guinea was settled more than 50,000 years ago, and served as a launch point for seafaring journeys into the wider Pacific. About 3300 years ago, the Lapita people — considered the earliest ancestors of many Pacific people, including Māori — settled in the Bismarck Archipelago, which became the cradle of the Lapita cultural complex. They were renowned for their intricate pottery and horticultural practices, and embarked on voyages that reached as far as Vanuatu, Tonga and Samoa. Rebecca Kinaston. PHOTO: ODT FILES Until now, the genomic legacy of these early Pacific pioneers had remained unexplored. Dr Tromp said one of the study's most striking findings was the presence of individuals with completely Papuan genetic signatures on the island of Watom, in the Bismarck Archipelago, where missionaries found the first Lapita-style pottery in the early 20th century. The individuals excavated on the island were all younger than evidence for the arrival of the Lapita Cultural Complex. "One of these individuals also displayed a rare case of cultural cranial modification, suggesting the co-occupation of the island by genetically and culturally different groups." Co-lead author and BioArch South director Dr Rebecca Kinaston said despite the co-occupation, it seemed the groups did not mix for a long time. The delay in intermarriage and the presence of people with Papuan ancestry might help answer a long-held question about whether the first settlers in the remote islands of Western Remote Oceania arrived unmixed, and mixed on the islands. The new findings supported the scenario. "Their ancestries started diverging 650 years ago, despite the absence of geographical borders."

Women's health advocate made ONZM
Celia Devenish Giddings. PHOTO: ODT FILES Fairlie woman Celia Devenish Giddings has been made an Officer of the New Zealand Order of Merit for services to women's health and education. Although working in Dunedin, Dr Devenish has lived with husband David Giddings on their Meadowslea farm for the past 45 years, commuting to work in Dunedin for 25 years, and prior to that to Timaru, Ashburton and Christchurch. The University of Otago School of Medicine teacher received the award in the King's Birthday Honours. Dr Devenish said she was "pleased" and "humbled" by the recognition, but had no plans to reduce her workload yet. In her 40 years as a doctor specialising in women's health issues, she has seen the environment change markedly. "Well, when I was a medical student in the UK and at Cambridge, I was fascinated by women's health and it was at a time when women's liberation was just beginning as a movement, I suppose, and people said, 'oh, you can't be an obstetrics and gynaecology services (OBG) specialist as a woman'. "There weren't any. So I said, 'well, I'll give it a go'." Dr Devenish has been a Fellow of the Royal Australian and New Zealand College of Obstetrics and Gynaecologists since 1981. She has held senior leadership roles including chairing the New Zealand Specialist International Medical Graduates Panel, serving as a member of the college council and board, and chairing the New Zealand governing committee Te Kahui Oranga o Nuku. She is a highly regarded teacher and mentor for undergraduates, midwives and registrars, working as senior lecturer and tutor at the University of Otago Dunedin School of Medicine since 1981. "I think women's health and teaching has changed dramatically. "When I first arrived in New Zealand, I was surprised to find I was the only specialist with a university appointment and academic interest to teach. "But because of that, I stayed and because I was asked to stay and promote women's health and women's perspectives, that's what I did. "I've done that for probably 45 years now." She said she loved nearly everything about teaching. "It's an amazing thing; seeing how excited the students are to think that they can be helpful to people and to understand what their needs are, what the women's needs are. "Options for medical students, especially women medical students, have grown a lot in the past 40 years," Dr Devenish said. "When I started at the medical school, about 10% of the student population were women. Now it's close to 60%." She also had a commitment to rural women because of living on a farm when she was not working. "And that means I understand the needs of women, whether it's from childbirth and need for transfer to access to care, which is so much more difficult when you have distance." While there was greater acceptance of women's health issues, Dr Devenish said the care on the ground was hampered by things such as long waiting lists. "But it's the most satisfying, exciting branch of medicine and health because it's a mixture of both meeting people from different cultures and needs and backgrounds and ethnicities. "It's an opportunity to provide medical advice as well as surgery. "So it's both a hands-on and a very holistic way of looking after people and families. "I hope never to give up teaching." — APL
