Clinical development has progressed through phase 2 trials in adults with obesity and type 2 diabetes, with phase 3 programs reported as ongoing. Reported outcomes include reductions in body weight and improvements in glycemic measures over defined treatment periods. Whether these effects translate into durable benefits after treatment ends remains an open question. Long-term safety data across broad populations are not yet complete, and regulatory decisions have not been announced.
Retatrutide is an investigational synthetic peptide engineered to activate three distinct hormone receptors within a single molecule. It targets the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor simultaneously. This triagonist design distinguishes it from earlier incretin-based compounds that act on one or two of these pathways. Structural modifications relative to native gut hormones extend its residence time in circulation. The molecule remains under clinical evaluation and is not approved for any indication.
Receptor activation produces downstream effects that differ by tissue. GLP-1 receptor signaling influences appetite regulation and insulin secretion in a glucose-dependent manner. GIP receptor activity contributes to metabolic handling of nutrients and may modulate adipose tissue. Glucagon receptor engagement raises energy expenditure and promotes hepatic lipid turnover, though the balance among these actions in humans is still being characterized. Preclinical models showed reductions in body weight and improved glycemic markers.
Identification and purity assessment rely on established analytical techniques. Reverse-phase high-performance liquid chromatography separates the compound from related impurities and degradation products. Mass spectrometry confirms molecular identity and detects modifications that change the expected mass. Additional methods such as amino acid analysis or capillary electrophoresis may be used for verification. Small differences in sample preparation can influence results, so procedures are usually controlled and documented in detail. Consistency between runs supports confidence in reported values.
Stability studies examine how the molecule changes under defined conditions of temperature, humidity, and light exposure over time. Results are used to set storage recommendations and shelf-life limits. In practice, lyophilized peptide material is often stored at low temperatures to slow degradation, while reconstituted solutions are handled more carefully because they are generally less stable. Reported stability data apply to specific formulations and conditions, so extrapolation to other preparations requires caution.

Several questions about the compound remain unresolved. The durability of weight reduction after treatment stops, the frequency of gastrointestinal side effects, and the long-term cardiovascular profile are topics of ongoing study. Regulatory submissions and phase 3 trial outcomes have not been fully reported in the public literature. Because most available data come from controlled trials rather than general-population use, conclusions about effectiveness outside study settings are provisional. The distinction between established findings and open questions matters when interpreting early coverage of the drug.
Retatrutide is an investigational peptide developed by a pharmaceutical company as a multi-receptor agonist for treating obesity and type 2 diabetes. The compound emerged from research into gut-hormone analogues that act on several receptors simultaneously rather than on a single target. Early preclinical work examined how combined activity at three distinct receptors might produce greater metabolic effects than single-receptor compounds. Published phase 2 results have described substantial reductions in body weight among participants, although the compound remains unapproved in most jurisdictions as of the mid-2020s.
Interpretation depends on study phase and duration. Phase 2 programs are powered for weight and safety signals, not for cardiovascular or renal outcomes, which require event-driven designs. Gastrointestinal events such as nausea, diarrhea, vomiting, and constipation are the most frequently reported adverse effects and tend to cluster around dose escalation. Small increases in heart rate have been described. Because follow-up after treatment discontinuation is limited, questions about weight regain and durability are open rather than answered.
Trial reports for this compound rely on a small set of repeated measures. Body weight is normally expressed as percent change from baseline at a fixed week, with absolute kilograms given secondarily. Glycemic endpoints include HbA1c, fasting glucose, and, in some protocols, continuous glucose monitoring summaries. Imaging endpoints such as MRI-derived proton density fat fraction quantify liver fat. Standardization matters because a percent change and a categorical responder analysis can tell different stories about the same dataset.
== Reception == The review-aggregator website Rotten Tomatoes reported a 100% approval rating based on 36 critic reviews. According to the website's critics' consensus: "Tackling emotionally mature themes with an ingeniously zany sense of humor, Raphael Bob-Waksberg's Long Story Short welcomes viewers into a highly specific—and extremely relatable—family unit". Metacritic, which uses a weighted average, gave a score of 89 out of 100 based on 17 critics, indicating "universal acclaim". Jenna Scherer of The A.V. Club gave the show's first season a rating of A− and wrote: "The series is all about how people change over the years—and the fact that, no matter how far you run, the past always returns to haunt the present". Reviewing the series' first season for The Guardian, Stuart Heritage gave a rating of 4/5, saying it "reminds us that everything is an echo of what came before. This is a testament to Bob-Waksberg's writing. This level of granular, non-linear character development must have been a feat to construct, and yet it feels effortless."
==== Partial re-escalation ==== In February, Frederiksen warned that Trump was still "very serious" about acquiring Greenland. On 21 February, Trump announced that he was sending a "hospital boat" to Greenland, claiming that many Greenlanders were sick and not receiving care. Earlier in the day, the Danish military had announced the evacuation of a crew member from an American submarine for a medical emergency. It is unknown if Trump was getting confused with that incident or was referring to something else. Trump's announcement drew widespread ridicule, with Prime Minister Nielsen saying "It's a no thank you from here" and many noting Greenland (and the Danish Realm) has nationalised healthcare, unlike the United States. On 8 April, during the 2026 Iran war, Trump posted on Truth Social about NATO allies "not being there" to join the war effort when the US "needed" them, referencing Greenland and referring to it as "that big, poorly run, piece of ice". On 7 July, during the 2026 Ankara NATO summit, Trump reiterated that the United States should have control of Greenland. Denmark rejected the proposal, with Prime Minister Mette Frederiksen reaffirming that Greenland was not for sale and that its sovereignty must be respected.

Secretary Wallace explained that these missiles were sent to Ukraine "to mitigate a situation where we (the UK) can't provide combat fighters." The US ambassador to South Africa Reuben Brigety accused the country of supplying weapons to Russia despite its professed neutrality in the war in Ukraine, claiming that the Russian ship Lady R was loaded with ammunition and arms at Naval Base Simon's Town in Cape Town on 6–8 December 2022. The office of President Cyril Ramaphosa expressed disappointment over the claims and said no evidence had been provided to support them. An independent inquiry later confirmed Ramaphos's claims, while the South African Foreign Ministry said Brigety "apologized unreservedly" for his remarks. A Russian court convicted 60-year old Saint Petersburg pensioner Irina Tsybaneva for desecrating the graves of President Vladimir Putin's parents at Serafimovskoe Cemetery. Tsybaneva, who was given a two-year suspended sentence, left a note at the Putin family plot referring to him as a "maniac", a "murderer" and a "monster" after claiming to have been "overwhelmed by fear" after watching news of the invasion of Ukraine. A military court sentenced history teacher Nikita Tushkanov of Komi Republic to five and a half years in prison for justifying "terrorism" and "discrediting" the Russian army after calling the Crimean Bridge explosion a "birthday present" for Putin in a social media post in October 2022.
=== Infection === Infection will complicate healing of surgical wounds and is commonly observed. Most infections are present within the first 30 days after surgery. Surgical wounds can become infected by bacteria, regardless if the bacteria is already present on the patient's skin or if the bacteria is spread to the patient due to contact with infected individuals. Wound infections can be superficial (skin only), deep (muscle and tissue), or spread to the organ or space where the surgery occurred. Recent studies have established that infection after surgery can occur after several years post surgery, and these infection rates are not recorded due to loss in patient follow up, hard to access record of previous surgery, visiting a new surgeon, lack of requirement from national registries etc.

Integrin alpha-11 is a protein that, in humans, is encoded by the ITGA11 gene. This gene encodes an alpha integrin. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This protein contains an I domain, is expressed in muscle tissue, dimerizes with beta 1 integrin in vitro, and appears to bind collagen in this form. Therefore, the protein may be involved in attaching muscle tissue to the extracellular matrix. Alternative transcriptional splice variants have been found for this gene, but their biological validity is not determined. According to one study, ITGA11 expression is increased in the anterior stroma of corneal buttons excised from the eyes affected by keratoconus. Another study showed that ITGA11 is overexpressed in myofibroblasts in different human fibrotic diseases, including liver cirrhosis, renal fibrosis, and lung fibrosis tissues. ITGA11 has also been found to be upregulated in the tumor stroma of pancreatic ductal adenocarcinoma. Knocking down of ITGA11 in human pancreatic stellate cells led to the inhibition of their differentiation into myofibroblasts and paracrine effect on tumor cells.
The kanji phrase 銀杏 ginkyō meaning 'silver apricot' had been attested in Chinese herbology literature such as 日用本草 (Daily Use Materia Medica) (1329) and Compendium of Materia Medica 本草綱目 published in 1578; 銀杏 was particular terminology used during the Song dynasty for tributary reasons in place of the then contemporary 鴨脚 ("duckfeet", from its leaves) in northeast China where it commonly grew. The older Chinese name for this plant is 銀果, meaning "silver fruit", pronounced yínguǒ in Mandarin or ngan-gwo in Cantonese, the current commonly used names are 白果 (bái guǒ) meaning 'white fruit'. Despite its spelling based on this complicated etymology, "ginkgo" is usually pronounced , which has given rise to the common alternative spelling "gingko". The spelling pronunciation is also documented in some dictionaries.

It is a synthetic peptide triagonist that engages GIP, GLP-1, and glucagon receptors. Investigational compounds in this class are studied for metabolic conditions rather than for a single organ system.
No regulatory agency has approved it for any indication. It remains an investigational product studied within controlled clinical trial programs.
A dual agonist engages two receptor targets, typically GIP and GLP-1. A triagonist adds glucagon receptor activity, which is intended to influence energy expenditure alongside appetite and glucose handling.
Reverse-phase liquid chromatography and mass spectrometry are the most common techniques. Chromatography assesses purity, while mass spectrometry confirms molecular identity. Additional methods may be applied when higher confidence is required.
