Self‑harm is an ‘act of self‑poisoning or self‑injury carried out by a person, irrespective of their motivation’. A history of self-harm is linked with suicide risk. A study in Pakistan found self-harm to be more common in young people with unemployment and interpersonal difficulties as common triggers. Expanding liaison psychiatry services leads to an earlier assessment of patients with self-harm.
To study the demographic and clinical variables of patients along with methods and precipitating factors of self-harm.
A retrospective chart review of patients presenting with self-harm seen as a part of liaison psychiatry from October 2018 to June 2021.
A total of 168 cases were seen of which 10 were excluded due to incomplete data. Of 158 cases gender split was roughly in the middle, with 49.4% males (n=78) and 50.6% females (n=80). The mean age of patients was 27.59 with a range of 12-70, 40.5% belonged to the age group of 20-29 (n=64) (Figure 1).
77.8% (n=123) had a past psychiatric history. The most common being depressive disorder 31.6% (n=50) and borderline personality disorder 30.4% (n=48). 35.4% of patients reportedly had previous attempts of self-harm. The most common methods being the use of sharp objects, rat-pill poisoning, and corrosive intake (Figure 2).
Conflicts with family and relationship difficulties were reported to be the most common precipitating factors.
Self-harm is a challenging and frequent presentation. Patients may present with diverse characteristics and varying needs. Hence physicians must be prepared for timely liaison and prompt management.

Geometric vertex decomposition and liaison are two frameworks that have been used to produce similar results about similar families of algebraic varieties. In this paper, we establish an explicit connection between these approaches. In particular, we show that each geometrically vertex decomposable ideal is linked by a sequence of elementary G-biliaisons of height 
$1$ to an ideal of indeterminates and, conversely, that every G-biliaison of a certain type gives rise to a geometric vertex decomposition. As a consequence, we can immediately conclude that several well-known families of ideals are glicci, including Schubert determinantal ideals, defining ideals of varieties of complexes and defining ideals of graded lower bound cluster algebras.
A central problem in liaison theory is to decide whether every arithmetically Cohen–Macaulay subscheme of projective 
$n$-space can be linked by a finite number of arithmetically Gorenstein schemes to a complete intersection. We show that this can indeed be achieved if the given scheme is also generically Gorenstein and we allow the links to take place in an 
$(n+ 1)$-dimensional projective space. For example, this result applies to all reduced arithmetically Cohen–Macaulay subschemes. We also show that every union of fat points in projective 3-space can be linked in the same space to a union of simple points in finitely many steps, and hence to a complete intersection in projective 4-space.
