BACKGROUND Little is known about the safety and efficacy of using two or more biologics for the treatment of immune-mediated diseases,including Crohn’s disease(CD).CASE SUMMARY This case report and narrative review demonstrate the potential safety of dual biologic therapy(DBT)in a 45-year-old female with two separate immunemediated diseases.She had a history of multiple sclerosis for which she was receiving treatment with ocrelizumab,and she had been recently diagnosed with CD after presenting with diarrhoea.The CD diagnosis was confirmed radiologically,endoscopically,histologically,and biochemically.The patient received treatment with vedolizumab,a gut-specific inhibitor of theα4β7 integrin on leukocytes.No adverse reactions were observed for the duration of treatment.The safety of ocrelizumab and vedolizumab for the treatment of different immune-mediated diseases was demonstrated.CONCLUSION DBT may be a safe and effective option for the treatment of refractory disease or multiple immunemediated diseases.Newer biologics,which have improved safety profiles and gut specificity,may provide promising avenues for treatment.However,caution must be exercised in the appropriate selection of biologics given their inherent immunosuppressive properties,side effects,and efficacy profiles.Current evidence suggests that biologic therapy is not associated with a worse prognosis in patients with coronavirus disease 2019,but treatment decisions should be made in a multidisciplinary setting.Further research from controlled trials is needed to better understand the safety profile of DBT in CD.The immunopathological mechanisms underlying DBT also remain to be clarified.

Surgical cystogastrostomy: Is it still worthwhile?

引用

World Journal of Gastroenterology 2024年第17期30卷 2298-2301页

作者： Kin Pan au Kenneth Siu Ho Chok Department of Surgery Queen Mary HospitalThe University of Hong KongHong Kong 999077China Department of Surgery The Chinese University of Hong KongHong Kong 999077China

The article by Ker et al explores the treatment of peripancreatic fluid collection(PFC).The use of percutaneous drainage,endoscopy,and surgery for managing PFC are discussed.Percutaneous drainage is noted for its low risk profile,while endoscopic cystogastrostomy is more effective due to the wider orifice of the metallic stent.Surgical cystogastrostomy is a definitive treatment with a reduced need for reintervention,especially for cases with extensive collections and significant necrosis.The choice of treatment modality should be tailored to individual patient characteristics and disease factors,considering the expertise available.

Minimum temperatures have remarkable impacts on tree growth at high-elevation sites on the Tibetan Plateau,but the shortage of long-term and high-resolution paleoclimate records inhibits understanding of recent minimum temperature anomalies.In this study,a warm season(April–September)reconstruction is presented for the past 467 years(1550–2016)based on Sabina tibetica ring-width chronology on the Lianbaoyeze Mountain of the central eastern Tibetan Plateau.Eight warm periods and eight cold periods were identified.Long-term minimum temperature variations revealed a high degree of coherence with nearby reconstructions.Spatial correlations between our reconstruction and global sea surface temperatures suggest that warm season minimum temperature anomalies in the central eastern Tibetan Plateau were strongly influenced by large-scale ocean atmospheric circulations,such as the El Ni?o-Southern Oscillation and the Atlantic Multidecadal Oscillation.

Journal of Forestry Research 2024年第1期35卷 72-82页

作者： Teng Li Jianfeng Peng Tsun Fung au Jingru Li Jinbao Li Yue Zhang School of Geography and Remote Sensing Guangzhou UniversityGuangzhou 510006People’s Republic of China College of Geography and Environmental Science Henan UniversityKaifeng 475004People’s Republic of China Institute for Global Change Biology School for Environment and SustainabilityUniversity of MichiganAnn ArborMIUSA Department of Ecology and Evolutionary Biology University of MichiganAnn ArborMIUSA Department of Geography University of Hong KongHong Kong SARPeople’s Republic of China HKU Shenzhen Institute of Research and Innovation Shenzhen 518057People’s Republic of China

Tree-ring chronologies were developed for Sabina saltuaria and Abies faxoniana in mixed forests in the Qionglai Mountains of the eastern Tibetan Plateau.Climate-growth relationship analysis indicated that the two co-exist-ing species reponded similarly to climate factors,although S.saltuaria was more sensitive than A.faxoniana.The strong-est correlation was between S.saltuaria chronology and regional mean temperatures from June to November.Based on this relationship,a regional mean temperature from June to November for the period 1605-2016 was constructed.Reconstruction explained 37.3%of the temperature variance during th period 1961-2016.Six major warm periods and five major cold periods were identified.Spectral analysis detected significant interannual and multi-decadal cycles.Reconstruction also revealed the influence of the Atlantic Multi-decadal Oscillation,confirming its importance on climate change on the eastern Tibetan Plateau.

Pearls of meta-analyses and systematic review in scientific evidence

引用

World Journal of Clinical Cases 2024年第16期12卷 2701-2703页

作者： Sunny Chi Lik au Department of Ophthalmology Tung Wah Eastern HospitalHong KongChina

Scientific evidence develops bit by bit from case reports,case series;to larger casecontrol,case-cohort;and further escalate to randomized controlled trials.This echoed the importance of continue publishing World journal of Clinical Cases,where novel and advancing discoveries start from a single case.In contrast,at the other end of the realm of evidence synthesis,systematic review and meta-analysis represent distinct yet interconnected processes.Butorphanol in epidural labor analgesia has long been studied since 1989,and with 70 publications from MEDLINE searches.However,there was no meta-analysis,nor any systematic review published so far.The latest in-press article published by Tang et al.on the protocol for the systematic review and meta-analysis on the safety and effectiveness of butorphanol in epidural labor analgesia is encouraging.We believe the findings of this study will be valuable for clinical practice as well as for future research.

Neuronal trafficking as a key to functional recovery in immune-mediated neuropathies

引用

Neural Regeneration Research 2024年第11期19卷 2331-2332页

作者： Felix Kohle michael Schroeter Department of Neurology University of Cologne and University Hospital CologneCologneGermany

Immune-mediated neuropathies are rare diseases of the peripheral nervous system(PNS),substantially affecting patients’functionality and quality of life.They are amenable to immunomodulatory treatments,which in many cases stabilize disease progression,but long-term deficits persist in many patients.Such long-term deficits are particularly observed in monophasic autoimmune neuropathies like Guillain-Barrésyndrome and also in chronic variants,e.g.,chronic inflammatory demyelinating neuropathy(Fadia et al.,2019).

It is a pleasure to write a commentary on the work of Dr.Hannah Rice and colleagues,l who have advanced our understanding of how the mechanical loading environment of the tibia changes as a function of running grade and speed.It is important that we understand how the tibia is loaded during conditions that an individual is likely to encounter when running as it is these internal loads which we believe are responsible for the development of bone-stress injuries.

Transcranial photobiomodulation for the brain: a wide range of clinical applications

引用

Neural Regeneration Research 2024年第3期19卷 483-484页

作者： michael R.Hamblin Laser Research Centre Faculty of Health ScienceUniversity of Johannesburg-Doornfontein CampusDoornfonteinSouth Africa

Photobiomodulation therapy(PBMT)is a rapidly growing approach to the healing,stimulation,protection,and regeneration of many human organs and tissue types.PBMT started in the 1960s as low-level laser therapy for wound healing,but since then the introduction of light-emitting diodes(LEDs)has dramatically increased the number of applications and reports of positive results.PBMT generally uses red(620-700 nm)and/or near-infrared(780-1270 nm)wavelengths of light at an intensity that causes no tissue heating,and its activity is based on well-established biological and cellular mechanisms(de Freitas and Hamblin,2016).While laser therapists continue to use various types of laser in their office practice,LEDs are ideally suited for home use devices because they are completely safe and without any known significant adverse effects.Among the various body parts on which PBMT has been shown to exert beneficial effects,the brain stands out as perhaps the most promising overall.PBMT has been shown to reduce neuroinflammation,while increasing mitochondrial function,oxygen consumption,and blood flow within the brain(Hamblin,2016).Moreover,PBMT can stimulate the processes of synaptogenesis,neurogenesis,and neuroplasticity thus helping the brain to heal itself.

Hepatobiliary & Pancreatic Diseases International 2024年第1期23卷 103-105页

作者： A michael Devane Christine MG Schammel Department of Radiology Prisma Health UpstateGreenvilleUSA Department of Pathology Prisma Health UpstateGreenvilleUSA

To the Editor:Biliary stricture formation at the bilioenteric anastomosis is an infrequent complication(2%-3%)after pancreaticoduodenectomy;the average presentation is within 13-14 months(range from 1 month to 9 years)after surgery[1,2].While the etiology is unknown,development of biliary stricture has shown to be more likely if a bile leak occurs in the postoperative period[3,4]and with younger patients[5].
