Autopsy diagnosis of acupuncture-induced bilateral tension pneumothorax using whole-body postmortem computed tomography: A case report

Effectiveness of acupuncture for irritable bowel syndrome: Protocol for a scoping review of systematic reviews and meta-analyses

BACKGROUND

Irritable bowel syndrome (IBS) is a common functional bowel disorder. Many systematic reviews/meta-analyses indicate that acupuncture and related therapies are effective for IBS. However, the robustness of the results in the systematic reviews and meta-analyses has not been evaluated. This scoping review aims to ascertain the credibility of current evidence of acupuncture therapy for IBS, to provide clinical research investigators with reliable information.

METHODS

Searches of China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), China Biology Medicine disc (CBMdisc), and Wanfang Database since the establishment of the database to February 2022. Study selection and data extraction will be conducted by 2 reviewers, and the quality will be assessed by 2 trained reviewers. We will use Assessment of Multiple Systematic Reviews-2 (AMSTAR2) for methodological quality assessment, Preferred Reporting Items for Systematic Reviews and Meta-Analyses for report quality assessment, Grading of Recommendations, Assessment, Development, and Evaluation for the quality of evidence assessment, and the Risk of Bias in Systematic Reviews for the bias assessment.

RESULTS

The results will be published in a peer-reviewed journal.

TRIAL REGISTRATION NUMBER

INPLASY202210117.

CONCLUSION

This scoping review will provide comprehensive evidence of acupuncture for patients with irritable bowel syndrome.

ETHICS AND DISSEMINATION

This scoping review does not require ethical approval as it is a secondary assessment of available literature.

Fatal bilateral pneumothoraces after electroacupuncture treatment: A case report and literature review

Acupuncture is practiced as a complementary medicine worldwide. Although it is considered a safe practice, pneumothorax is one of its most common serious complications. However, there have been few reports of deaths due to pneumothorax after acupuncture treatment, especially focused on electroacupuncture. We report an autopsy case of a man in his 60s who went into cardiopulmonary arrest and died immediately after receiving electroacupuncture. Postmortem computed tomography (PMCT) showed bilateral pneumothoraces, as well as the presence of numerous gold threads embedded subcutaneously. An autopsy revealed two ecchymoses in the right thoracic cavity and a pinhole injury on the lower lobe of the right lung, suggesting that the needles had penetrated the lung. There were marked emphysematous changes in the lung, suggesting that rupture of bullae might also have contributed to bilateral pneumothoraces and fatal outcome. The acupuncture needles may have been drawn deeper into the body than at the time of insertion due to electrical pulses and muscle contraction, indicating the need for careful determination of treatment indications and technical safety measures, such as fail-safe mechanisms. This is the first case report of fatal bilateral pneumothoraces after electroacupuncture reported in the English literature. This case sheds light on the safety of electroacupuncture and the need for special care when administering it to patients with pulmonary disease who may be at a higher risk of pneumothorax. This is also the first report of three-dimensional reconstructed PMCT images showing the whole-body distribution of embedded gold acupuncture threads, which is unusual.

The study protocol for a randomized, controlled trial of acupuncture versus a sham procedure versus standard care alone for the treatment of delirium in acutely hospitalized older adults with a medical illness

BACKGROUND

Many hospitalized older adults experience delirium, but treatment options are limited. Acupuncture has been shown to improve cognitive function and reduce agitation in dementia. We hypothesize that acupuncture, when compared with a sham intervention, will reduce the duration and severity of delirium, normalize delirium biomarkers, and improve clinical outcomes related to delirium in acutely hospitalized older adults with a medical illness.

METHODS

This three-arm, prospective, randomized, clinical trial will evaluate adults aged over 65 years who are acutely hospitalized to an internal-medicine ward and diagnosed with delirium or subsyndromal delirium. The 288 patients (96 in each of three groups) will be randomly allocated to receive either daily true acupuncture with usual care, a daily sham procedure with usual care, or usual care only in a 1:1:1 distribution for up to one week or until the patient is delirium-free for over 48 h. Other delirium and clinical interventions will remain unchanged. Delirium will be diagnosed using DSM-5 criteria and its severity will be assessed using the long Confusion Assessment Method Severity (CAM-S) tool.

OUTCOMES

The primary study outcome will be the daily CAM-S score over 7 days between the three groups. Secondary outcomes will include time to first resolution of the delirium (over 7 days), the proportion of days spent delirium-free, daily antipsychotic use, daily pain scores, sleep quality, morning serum cortisol and T3 levels, and midnight urinary cortisol/creatinine ratio, all determined twice a week, and delirium-related complications. Hospital mortality, duration of hospital stay and functional status at discharge will also be compared between the three groups. Adverse events potentially related to acupuncture will be evaluated daily. The cost-effectiveness of acupuncture will be estimated.

CONCLUSION

This novel randomized study will evaluate both the specific and the non-specific effects of acupuncture on delirium, and related outcomes, and its safety. Potential mechanism(s) of action for acupuncture in reducing delirium will be explored and healthcare-related costs estimated. Positive study results may prove pivotal in facilitating a multimodal, non-pharmacologic, integrative approach to delirium treatment among older, medical inpatients.
